&lt;br /&gt;
With new technologies come new impacts. We will be looking at the unseen and hard to detect impact of our increasing use of “hidden” plastic - plastic that we can’t see, like microbeads, or that we don’t have a narrative of as polluting, such as 3D printed materials. We’ll be refining the DIY chemical tests that we developed at Piksel 2015, extending them from analysing the microplastics in fish to looking at fish market samples.  &lt;br /&gt;
&lt;br /&gt;
Over a 1+3 day workshop at S.Net, we’ll take the participants through a process of sample collection on a field trip onto the fish market, and an exploration of these newly developed DIY techniques, to understand better the presence of plastic in the marine environment around Bergen. &lt;br /&gt;
&lt;br /&gt;
The workshops will culminate with a Sushi Roulette afterparty, where through the presence of real and dummy sushi the participants are challenged to test their reactions to the thought of consuming plastics as food.&lt;br /&gt;

Ingested plastic transfers hazardous chemicals to fish and induces hepatic stress [http://www.nature.com/articles/srep03263]&amp;lt;br&amp;gt;&lt;br /&gt;
=== Microplastics in Norway ===&lt;br /&gt;
&#039;&#039;&#039;Distribution of microplastics in marine environments from Norwegian Env Agency&#039;&#039;&#039;&amp;lt;br&amp;gt;&lt;br /&gt;
http://www.miljodirektoratet.no/Documents/publikasjoner/M319/M319.pdf &amp;lt;br&amp;gt;&lt;br /&gt;
&amp;quot;The effects of microplastics on marine organisms are typically sub-lethal, such as reduced feeding and increased uptake of certain contaminants (e.g. polychlorinatedbiphenyls). Laboratory exposure to microplastics shows negative impact such as a reduction in the growth of marine worms and changes in gene regulation in fish.&amp;quot;&amp;lt;br&amp;gt;&lt;br /&gt;
&amp;quot;The significance of microplastic pollution on the safety of seafood is not known, although it is important to note that the concentrations determined in the farmed mussels and oysters are relatively small. If eating 250 g of blue mussels one will consume 90 particles, and 6 oysters of 100 g per the portion will contain around 50 particles54. Although, based upon the yearly consumption of shellfish in Europe the number increases to 11,000 particles person-1 year-1 54.&amp;quot;&amp;lt;br&amp;gt;&lt;br /&gt;
&amp;quot;Even though a large number of fish species have been examined to date, the spatial coverage of such studies is relatively poor with insufficient data to decipher any spatial trends. The number of microplastics found in the digestive system of fish is typically between 1 and 7.2 (Table 6). In the English Channel less dense polymers, such as polystyrene and LDPE (Table 2) were only found in pelagic feeding fish, however, less dense polymers where found in fish that fed in both pelagic and demersal waters. The plastics polymers found in the English channel are known to be used a lot in the fishing industry, which may be a possible source94.&amp;quot;&lt;br /&gt;
&amp;quot;there is considerable potential for bioaccumulation and trophic transfer of microplastics in food chains, such that higher predators, including human consumers of seafood products, may possibly be exposed to relatively high levels of micro plastics&amp;quot;&amp;lt;br&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Marine microplstic pollution in Norway&#039;&#039;&#039;&amp;lt;br&amp;gt; http://epanet.pbe.eea.europa.eu/.../microplastic-pollution-norway.../S2%205_Kjeldby.pdf&amp;lt;br&amp;gt;&lt;br /&gt;
&lt;br /&gt;
===Impact of Microplastics===&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Plastic poisons in the food chain&#039;&#039;&#039; &amp;lt;br&amp;gt;&lt;br /&gt;
http://www.i-sis.org.uk/Plastic_Poisons_in_the_Food_Chain.php&amp;lt;br&amp;gt;&lt;br /&gt;
Plastic wastes are not only physically harmful. They may be chemically harmful either because they are inherently toxic, or because they absorb other pollutants that are toxic. As pointed out in a recent review [6], microplastics can be ingested by suspension- filter- and deposit- feeders, detritivores and planktivores, all at the bottom of the food web. They may accumulate within the organisms, resulting in both physical and chemical damage. They can cause abrasions and blockages. And toxicity could arise from contaminants leaching from the microplastics such as monomers and plastic additives that are carcinogenic and/or endocrine disrupting. Moreover, microplastics can concentrate hydrophobic persistent organic pollutants (POPs) that have a greater affinity for the hydrophobic surface of plastics compared to seawater.  On account of their large surface area to volume ratio, microplastics can become heavily contaminated, at up to 6 orders of magnitude greater than ambient seawater in the case of waterborne POPs [7, 8].&amp;lt;br&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Ingested plastic transfers hazardous chemicals to fish and induces hepatic stress&#039;&#039;&#039;&amp;lt;br&amp;gt;&lt;br /&gt;
http://www.nature.com/articles/srep03263&amp;lt;br&amp;gt;&lt;br /&gt;
Plastic debris litters aquatic habitats globally, the majority of which is microscopic (&amp;lt; 1 mm), and is ingested by a large range of species. Risks associated with such small fragments come from the material itself and from chemical pollutants that sorb to it from surrounding water. Hazards associated with the complex mixture of plastic and accumulated pollutants are largely unknown. Here, we show that fish, exposed to a mixture of polyethylene with chemical pollutants sorbed from the marine environment, bioaccumulate these chemical pollutants and suffer liver toxicity and pathology. Fish fed virgin polyethylene fragments also show signs of stress, although less severe than fish fed marine polyethylene fragments. We provide baseline information regarding the bioaccumulation of chemicals and associated health effects from plastic ingestion in fish and demonstrate that future assessments should consider the complex mixture of the plastic material and their associated chemical pollutants.&amp;lt;br&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Environmentally relevant concentrations of microplastic particles influence larval fish ecology&#039;&#039;&#039;&amp;lt;br&amp;gt;&lt;br /&gt;
http://science.sciencemag.org/content/352/6290/1213&amp;lt;br&amp;gt;&lt;br /&gt;
The widespread occurrence and accumulation of plastic waste in the environment have become a growing global concern over the past decade. Although some marine organisms have been shown to ingest plastic, few studies have investigated the ecological effects of plastic waste on animals. Here we show that exposure to environmentally relevant concentrations of microplastic polystyrene particles (90 micrometers) inhibits hatching, decreases growth rates, and alters feeding preferences and innate behaviors of European perch (Perca fluviatilis) larvae. Furthermore, individuals exposed to microplastics do not respond to olfactory threat cues, which greatly increases predator-induced mortality rates. Our results demonstrate that microplastic particles operate both chemically and physically on larval fish performance and development.&amp;lt;br&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Microplastic ingestion by scleractinian corals&#039;&#039;&#039;&amp;lt;br&amp;gt;&lt;br /&gt;
http://link.springer.com/article/10.1007/s00227-015-2619-7&amp;lt;br&amp;gt;&lt;br /&gt;
We report for the first time the ingestion of microplastics by scleractinian corals, and the presence of microplastics in coral reef waters adjacent to inshore reefs on Australia’s Great Barrier Reef (GRE, 18°31′S 146°23′E). Analysis of samples from sub-surface plankton tows conducted in close proximity to inshore reefs on the central GBR revealed microplastics, similar to those used in marine paints and fishing floats, were present in low concentrations at all water sampling locations. Experimental feeding trials revealed that corals mistake microplastics for prey and can consume up to ~50 μg plastic cm−2 h−1, rates similar to their consumption of plankton and Artemia nauplii in experimental feeding assays. Ingested microplastics were found wrapped in mesenterial tissue within the coral gut cavity, suggesting that ingestion of high concentrations of microplastic debris could potentially impair the health of corals.&amp;lt;br&amp;gt;&lt;br /&gt;
&lt;br /&gt;
===Novel sources of Microplastics===&lt;br /&gt;
&#039;&#039;&#039;Hiking clothes create microplastic pollution in Svalbard&#039;&#039;&#039;&amp;lt;br&amp;gt;&lt;br /&gt;
http://svalbardposten.no/nyheter/turklar-skaper-trobbel-for-fjordlivet/19.6899&amp;lt;br&amp;gt;&lt;br /&gt;
 We are primarily filamentous plastic particles of different colors and types.These findings show that households in Svalbard in the Arctic contributes to the discharge of plastic waste, and perhaps to a greater extent than we like to think about, says oceanographer Jan H. Sundet IMR. &amp;lt;br&amp;gt;&lt;br /&gt;

&#039;&#039;&#039;Kat Austen&#039;&#039;&#039;&lt;br /&gt;
http://katausten.com http://worldflows.net.  &lt;br /&gt;
Kat F Austen is a succession of experiences and an assemblage of aspirations.  In the temporal melting-pot of her life so far she has produced work as an artist, an environmental scientist, a journalist, a writer and much in  between.&lt;br /&gt;
&lt;br /&gt;
As an artist Kat deals with themes of environment, social justice, communities and human relations to digital culture. She creates experiences, stories and playful installations, mixing fact and fiction closely, so troublesome. She wants to touch your heart, mind, soul, body. &lt;br /&gt;
&lt;br /&gt;
Kat is Artist in Residence at the Faculty of  Maths and Physical Sciences, University College London, and has been artist for LAStheatre, The Clipperton Project and Utter! Spoken word,  among others. She has exhibited widely, including at Museo Diego Rivera, Mexico City, Kulurbraueri, Berlin, Kreuzberg Pavillion, Berlin, The Crystal, London, Schwartz Gallery, London, Regenerate Gallery, London and Williams Art, Cambridge, among others. She has presented on interdisciplinary internationally and has run artistic workshops in Germany, the Netherlands, Italy and the UK. She is Head of  Research and Design at social enterprise  iilab, leading the Open  Droplet water sensor project, which was recently  included on the  Serpentine Gallery’s extinct.ly platform. With this project, she is focussing on co-design, physically evocative representations of data and community stewardship of water.&lt;br /&gt;
&lt;br /&gt;
Kat holds a PhD in chemistry from UCL and worked as a post-doctoral research associate at the University of Cambridge. Her writing has appeared in two book chapters, New Scientist, Nature, The Ecologist and The Guardian, and she consults widely on the intersection of science, art and technology, including as a Futureshaper for Forum for the Future, for the European Commission and UK water regulator Ofwat. &lt;br /&gt;
&lt;br /&gt;
The environment is Kat’s passion, and her interest is largely held by finding  intellectual, experiential and sensorial ways of understanding existence in all its complexity. Her work explores the interplay between acts at different levels - individual, collective, communal, municipal, state, national, international - in the context of a global, digitally-enabled society. The aesthetics in her artworks treads the line between naive and polished, messy and sleek, humorous and disjointed. For instance, she drowned a lot of tiny people in a bath to make a point about social media. Kat has a PADI open water diving license and also licence to be crew on the yacht.&lt;br /&gt;

&lt;br /&gt;
Since 2012. started a public work by displaying his inventions and innovations such as; &lt;br /&gt;
SRCE, B.O.C.A., MeBUMZ etc., in a variety of scientific and art exhibitions and cultural &lt;br /&gt;
events in Croatia and abroad. Also, started teaching as an informal educator in biotweaking areas of science. &lt;br /&gt;
&lt;br /&gt;
His work combines complex electronics and biotechnology, and he often uses artistic representation for the demystification of science and for bringing it closer to ordinary &lt;br /&gt;
citizens. &lt;br /&gt;
&lt;br /&gt;
In 2013. founded and started working as CEO &amp;amp; CSO of non-profit citizen’s Universal &lt;br /&gt;
Research Institute UR, where he also holds workshops, teaches and experiments.&lt;br /&gt;

===Impact of Microplastics===&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Plastic poisons in the food chain&#039;&#039;&#039; &amp;lt;br&amp;gt;&lt;br /&gt;
http://www.i-sis.org.uk/Plastic_Poisons_in_the_Food_Chain.php&amp;lt;br&amp;gt;&lt;br /&gt;
Plastic wastes are not only physically harmful. They may be chemically harmful either because they are inherently toxic, or because they absorb other pollutants that are toxic. As pointed out in a recent review [6], microplastics can be ingested by suspension- filter- and deposit- feeders, detritivores and planktivores, all at the bottom of the food web. They may accumulate within the organisms, resulting in both physical and chemical damage. They can cause abrasions and blockages. And toxicity could arise from contaminants leaching from the microplastics such as monomers and plastic additives that are carcinogenic and/or endocrine disrupting. Moreover, microplastics can concentrate hydrophobic persistent organic pollutants (POPs) that have a greater affinity for the hydrophobic surface of plastics compared to seawater.  On account of their large surface area to volume ratio, microplastics can become heavily contaminated, at up to 6 orders of magnitude greater than ambient seawater in the case of waterborne POPs [7, 8].&amp;lt;br&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Ingested plastic transfers hazardous chemicals to fish and induces hepatic stress&#039;&#039;&#039;&amp;lt;br&amp;gt;&lt;br /&gt;
http://www.nature.com/articles/srep03263&amp;lt;br&amp;gt;&lt;br /&gt;
Plastic debris litters aquatic habitats globally, the majority of which is microscopic (&amp;lt; 1 mm), and is ingested by a large range of species. Risks associated with such small fragments come from the material itself and from chemical pollutants that sorb to it from surrounding water. Hazards associated with the complex mixture of plastic and accumulated pollutants are largely unknown. Here, we show that fish, exposed to a mixture of polyethylene with chemical pollutants sorbed from the marine environment, bioaccumulate these chemical pollutants and suffer liver toxicity and pathology. Fish fed virgin polyethylene fragments also show signs of stress, although less severe than fish fed marine polyethylene fragments. We provide baseline information regarding the bioaccumulation of chemicals and associated health effects from plastic ingestion in fish and demonstrate that future assessments should consider the complex mixture of the plastic material and their associated chemical pollutants.&amp;lt;br&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Environmentally relevant concentrations of microplastic particles influence larval fish ecology&#039;&#039;&#039;&amp;lt;br&amp;gt;&lt;br /&gt;
http://science.sciencemag.org/content/352/6290/1213&amp;lt;br&amp;gt;&lt;br /&gt;
The widespread occurrence and accumulation of plastic waste in the environment have become a growing global concern over the past decade. Although some marine organisms have been shown to ingest plastic, few studies have investigated the ecological effects of plastic waste on animals. Here we show that exposure to environmentally relevant concentrations of microplastic polystyrene particles (90 micrometers) inhibits hatching, decreases growth rates, and alters feeding preferences and innate behaviors of European perch (Perca fluviatilis) larvae. Furthermore, individuals exposed to microplastics do not respond to olfactory threat cues, which greatly increases predator-induced mortality rates. Our results demonstrate that microplastic particles operate both chemically and physically on larval fish performance and development.&amp;lt;br&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Microplastic ingestion by scleractinian corals&#039;&#039;&#039;&amp;lt;br&amp;gt;&lt;br /&gt;
http://link.springer.com/article/10.1007/s00227-015-2619-7&amp;lt;br&amp;gt;&lt;br /&gt;
We report for the first time the ingestion of microplastics by scleractinian corals, and the presence of microplastics in coral reef waters adjacent to inshore reefs on Australia’s Great Barrier Reef (GRE, 18°31′S 146°23′E). Analysis of samples from sub-surface plankton tows conducted in close proximity to inshore reefs on the central GBR revealed microplastics, similar to those used in marine paints and fishing floats, were present in low concentrations at all water sampling locations. Experimental feeding trials revealed that corals mistake microplastics for prey and can consume up to ~50 μg plastic cm−2 h−1, rates similar to their consumption of plankton and Artemia nauplii in experimental feeding assays. Ingested microplastics were found wrapped in mesenterial tissue within the coral gut cavity, suggesting that ingestion of high concentrations of microplastic debris could potentially impair the health of corals.&amp;lt;br&amp;gt;&lt;br /&gt;
&lt;br /&gt;
===Novel sources of Microplastics===&lt;br /&gt;
&#039;&#039;&#039;Hiking clothes create microplastic pollution in Svalbard&#039;&#039;&#039;&amp;lt;br&amp;gt;&lt;br /&gt;
http://svalbardposten.no/nyheter/turklar-skaper-trobbel-for-fjordlivet/19.6899&amp;lt;br&amp;gt;&lt;br /&gt;
 We are primarily filamentous plastic particles of different colors and types.These findings show that households in Svalbard in the Arctic contributes to the discharge of plastic waste, and perhaps to a greater extent than we like to think about, says oceanographer Jan H. Sundet IMR. &amp;lt;br&amp;gt;&lt;br /&gt;

&#039;&#039;&#039;Kat Austen&#039;&#039;&#039;&lt;br /&gt;
http://katausten.com http://worldflows.net http://opendroplet.org.  &lt;br /&gt;
Kat F Austen is a succession of experiences and an assemblage of aspirations.  In the temporal melting-pot of her life so far she has produced work as an artist, an environmental scientist, a journalist, a writer and much in  between.&lt;br /&gt;
&lt;br /&gt;
As an artist Kat deals with themes of environment, social justice, communities and human relations to digital culture. She creates experiences, stories and playful installations, mixing fact and fiction closely, so troublesome. She wants to touch your heart, mind, soul, body. &lt;br /&gt;
&lt;br /&gt;
Kat is Artist in Residence at the Faculty of  Maths and Physical Sciences, University College London, and has been artist for LAStheatre, The Clipperton Project and Utter! Spoken word,  among others. She has exhibited widely, including at Museo Diego Rivera, Mexico City, Kulurbraueri, Berlin, Kreuzberg Pavillion, Berlin, The Crystal, London, Schwartz Gallery, London, Regenerate Gallery, London and Williams Art, Cambridge, among others. She has presented on interdisciplinary internationally and has run artistic workshops in Germany, the Netherlands, Italy and the UK. She is Head of  Research and Design at social enterprise  iilab, leading the Open  Droplet water sensor project, which was recently  included on the  Serpentine Gallery’s extinct.ly platform. With this project, she is focussing on co-design, physically evocative representations of data and community stewardship of water.&lt;br /&gt;
&lt;br /&gt;
Kat holds a PhD in chemistry from UCL and worked as a post-doctoral research associate at the University of Cambridge. Her writing has appeared in two book chapters, New Scientist, Nature, The Ecologist and The Guardian, and she consults widely on the intersection of science, art and technology, including as a Futureshaper for Forum for the Future, for the European Commission and UK water regulator Ofwat. &lt;br /&gt;
&lt;br /&gt;
The environment is Kat’s passion, and her interest is largely held by finding  intellectual, experiential and sensorial ways of understanding existence in all its complexity. Her work explores the interplay between acts at different levels - individual, collective, communal, municipal, state, national, international - in the context of a global, digitally-enabled society. The aesthetics in her artworks treads the line between naive and polished, messy and sleek, humorous and disjointed. For instance, she drowned a lot of tiny people in a bath to make a point about social media. Kat has a PADI open water diving license and also licence to be crew on the yacht.&lt;br /&gt;

&lt;br /&gt;
Since 2012. started a public work by displaying his inventions and innovations such as; &lt;br /&gt;
SRCE, B.O.C.A., MeBUMZ etc., in a variety of scientific and art exhibitions and cultural &lt;br /&gt;
events in Croatia and abroad. Also, started teaching as an informal educator in biotweaking areas of science. &lt;br /&gt;
&lt;br /&gt;
His work combines complex electronics and biotechnology, and he often uses artistic representation for the demystification of science and for bringing it closer to ordinary &lt;br /&gt;
citizens. &lt;br /&gt;
&lt;br /&gt;
In 2013. founded and started working as CEO &amp;amp; CSO of non-profit citizen’s Universal &lt;br /&gt;
Research Institute UR, where he also holds workshops, teaches and experiments.&lt;br /&gt;

Information from the DIY microplastic experimentation and conversations with researchers from Bergen&#039;s Marine Institute, alongside sound recordings from the hydrophone field trips, informed the design of a prototype Coral Empathy Device. The device obliterates the visual, employing sound, pressure, texture and smell to translate messages of anthropogenic marine intervention between the experience of coral in the Norwegian waters and the experience of humans on terra. Liquid to air, coral to human, the Coral Empathy Device prototype is an experiment in interspecies empathy.&lt;br /&gt;

Pikslo_deep_diving // Context &amp;amp; concept of the workshop / research:&lt;br /&gt;
&lt;br /&gt;
by Robertina Šebjanič (SI), Kat Austen (UK/D), Slavko Glamočanin(SI), Gjino Šutić (CRO)&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
When we look up to sky and look into the space and wonder about what is up there, we&lt;br /&gt;
&lt;br /&gt;
sometime forget, that there is a lot still also to explore on the planet we live.&lt;br /&gt;
&lt;br /&gt;
We know more about the space than we know about the world’s seas and oceans,&lt;br /&gt;
&lt;br /&gt;
especially about the sound perception underwater.&lt;br /&gt;
&lt;br /&gt;
People are not so aware of the vibrant underwater acoustic of sounds of the deepness of&lt;br /&gt;
&lt;br /&gt;
ocean, except for the crash of a wave against a land. Whales, shrimp, seals, dolphins, and a&lt;br /&gt;
&lt;br /&gt;
variety of other creatures of the deep live in a watery acoustical ­ sonic environment. The&lt;br /&gt;
&lt;br /&gt;
arrival of steamships and other human­made interventions into the ocean soundscape has&lt;br /&gt;
&lt;br /&gt;
contributed disturbing noise to this rich soundscape.&lt;br /&gt;
&lt;br /&gt;
The workshop / project encourage an inter­relationship between sound, nature, and&lt;br /&gt;
&lt;br /&gt;
society, as a starting point for the rethinking of the possible developed of nicer sonic&lt;br /&gt;
&lt;br /&gt;
environments for the animals living in the world&#039;s oceans and sea’s.&lt;br /&gt;
&lt;br /&gt;
The underwater sound pollution is the reality of recent development and industrialization&lt;br /&gt;
&lt;br /&gt;
reflecting on the sea.&lt;br /&gt;
&lt;br /&gt;
Especially the upper level of the seas ­ where there is most of the living in the seas and&lt;br /&gt;
&lt;br /&gt;
independent by the level of the sonic pollution in the sea. We would also try to research the&lt;br /&gt;
&lt;br /&gt;
deep sea level to understand what is happening there.&lt;br /&gt;
&lt;br /&gt;
World seas and oceans are presenting more than 70% of surface of Earth.&lt;br /&gt;
&lt;br /&gt;
97% of it is saltwater, 2% is fresh water in the form of ice and only the remaining 1% is&lt;br /&gt;
&lt;br /&gt;
drinking water, which is distributed around the planet very unevenly.&lt;br /&gt;
&lt;br /&gt;
The exploration of any ecosystem requires detailed study and observation. The ocean is the&lt;br /&gt;
&lt;br /&gt;
complex, challenging, and harsh environment on Earth and accessing it requires specially&lt;br /&gt;
&lt;br /&gt;
designed tools and technology. It has only been within the last 50 years that technology has&lt;br /&gt;
&lt;br /&gt;
advanced to the point that we can examine the ocean in a systematic, scientific, and non&lt;br /&gt;
&lt;br /&gt;
invasive way. Our ability to observe the ocean environment and its resident creatures has&lt;br /&gt;
&lt;br /&gt;
finally caught up with our imaginations and helping us to understand it also in the ways that&lt;br /&gt;
&lt;br /&gt;
we did not imagine them before.&lt;br /&gt;
&lt;br /&gt;
“&#039;&#039;Already back at the renaissance 1490 Leonardo da Vinci observed how the sound of ships&lt;br /&gt;
&lt;br /&gt;
travelled long distances underwater. The sound of ships in the 15th century included the&lt;br /&gt;
&lt;br /&gt;
noise of rudders and rigging, oars and the handling of cargo. Seafaring, while not in its&lt;br /&gt;
&lt;br /&gt;
infancy, was a “life driven” technology; the power of wind and human muscle generated the&lt;br /&gt;
&lt;br /&gt;
only anthropogenic noises in the sea. Over the next 400 years, acoustic technology at sea&lt;br /&gt;
&lt;br /&gt;
involved innovations such as underwater bells and whistling buoys on submerged rocks and&lt;br /&gt;
&lt;br /&gt;
reefs to warn navigators and captains away from marine hazards. With the advent of steam&lt;br /&gt;
&lt;br /&gt;
powered engines, the quality and level of noise began to shift dramatically. With the ability to&lt;br /&gt;
&lt;br /&gt;
navigate to, and develop the far reaches of the globe, the use of dynamite and diesel driven&lt;br /&gt;
&lt;br /&gt;
pile drivers began transforming the soundscape of coastal waters worldwide. Once the&lt;br /&gt;
&lt;br /&gt;
mechanization of seafaring and coastal civil engineering took hold, ocean noise began&lt;br /&gt;
&lt;br /&gt;
increasing exponentially&#039;&#039;” * (from the Soundscape The Journal of Acoustic Ecology​) and&lt;br /&gt;
&lt;br /&gt;
it started to overtake also the sound scape environment of the animals.&lt;br /&gt;

Marine Life&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
The sounds produced by marine animals are many and varied. Marine mammals, such as&lt;br /&gt;
&lt;br /&gt;
blue whales and harbor porpoise, produce sounds over a wide frequency range, from less&lt;br /&gt;
&lt;br /&gt;
than 10 Hz to over 100,000 Hz, depending on the species of marine mammal. Many fish,&lt;br /&gt;
&lt;br /&gt;
such as the oyster toadfish and plainfin midshipman, and some marine invertebrates, such&lt;br /&gt;
&lt;br /&gt;
as snapping shrimp, also produce sounds. Marine animals use sound to obtain detailed&lt;br /&gt;
&lt;br /&gt;
information about their surroundings. They rely on sound to communicate, navigate, and&lt;br /&gt;
&lt;br /&gt;
feed. Marine mammals, such as dolphins, use sound to locate and identify objects such as&lt;br /&gt;
&lt;br /&gt;
food, obstacles, and other whales. By emitting clicks, or short pulses of sound, and listening&lt;br /&gt;
&lt;br /&gt;
to the echo, dolphins can detect individual prey and navigate around objects underwater.&lt;br /&gt;

&#039;&#039;&#039;Salt-Water Fish Extinction Seen By 2048&#039;&#039;&#039;&lt;br /&gt;
The apocalypse has a new date: 2048.&lt;br /&gt;
&lt;br /&gt;
That&#039;s when the world&#039;s oceans will be empty of fish, predicts an international team of ecologists and economists. The cause: the disappearance of species due to overfishing, pollution, habitat loss, and climate change.&lt;br /&gt;
&lt;br /&gt;
The study by Boris Worm, PhD, of Dalhousie University in Halifax, Nova Scotia, -- with colleagues in the U.K., U.S., Sweden, and Panama -- was an effort to understand what this loss of ocean species might mean to the world.&lt;br /&gt;
&lt;br /&gt;
The researchers analyzed several different kinds of data. Even to these ecology-minded scientists, the results were an unpleasant surprise.&lt;br /&gt;

&#039;&#039;&#039;Cnidaria ­ jellyfish hearing under the water&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
At present there is still a dearth of research and understanding about how Cnidaria—with&lt;br /&gt;
&lt;br /&gt;
their ancient evolutionary history— actually perceive and adapt to their environment through&lt;br /&gt;
&lt;br /&gt;
acoustic energy and vibration, and how this has enabled them to survive over the eons&lt;br /&gt;
&lt;br /&gt;
despite their ‘simplicity.’&lt;br /&gt;
&lt;br /&gt;
Marine mammal calls can actually increase ambient noise levels by 20­25 underwater dB in&lt;br /&gt;
&lt;br /&gt;
some locations at certain times of year. Blue and fin whales produce low­frequency moans&lt;br /&gt;
&lt;br /&gt;
at frequencies of 10­25 Hz with estimated source levels of up to 190 underwater dB at 1 m.&lt;br /&gt;
&lt;br /&gt;
The ambient noise levels at frequencies of 17­20 Hz increase off coastal California during&lt;br /&gt;
&lt;br /&gt;
the fall and winter months due to blue and fin whale calls.&lt;br /&gt;

&#039;&#039;&#039;Animal Sound Perception and Production Modes&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
From the preceding it is clear that many sea animals use sound in a variety of ways. Some&lt;br /&gt;
&lt;br /&gt;
animals use sound passively, others actively. Passive use of sound occurs when the animal&lt;br /&gt;
&lt;br /&gt;
does not create the sound that it senses, but responds to environmental and ambient&lt;br /&gt;
&lt;br /&gt;
sounds. These uses include: 1. Detection of predators. 2. Location and detection of prey. 3.&lt;br /&gt;
&lt;br /&gt;
Proximity perception of co­species in school, raft or colony. 4. Navigation—either local or&lt;br /&gt;
&lt;br /&gt;
global. 5. Perception of changing environmental conditions such as seismic movement, tides&lt;br /&gt;
&lt;br /&gt;
and currents. 6. Detection of food sources and feeding of other animals. 7. “Acoustic&lt;br /&gt;
&lt;br /&gt;
illumination” akin to daylight vision. Active use of sound occurs when the animal creates a&lt;br /&gt;
&lt;br /&gt;
sound to interact with their environment or other animals in it. Active uses include: 1. Sonic&lt;br /&gt;
&lt;br /&gt;
communication with co­species for breeding. 2. Sonic communication with co­species for&lt;br /&gt;
&lt;br /&gt;
feeding, including notification and guidance of others to food sources. 3. Territorial and&lt;br /&gt;
&lt;br /&gt;
social relations. 4. Echolocation. 5. Stunning and apprehending prey. 6. Alarm calls used to&lt;br /&gt;
&lt;br /&gt;
notify other creatures of the approach of enemies. 7. Long distance navigation and mapping.&lt;br /&gt;
&lt;br /&gt;
8. Use of sound as a defense against predators. 9. Use of sound when seized by a predator&lt;br /&gt;
&lt;br /&gt;
(perhaps to startle the predator).&lt;br /&gt;

Some results of a four‐year experimental study of sound propagation in the Arctic are presented and interpreted. The duration, form, and intensity of waves received at distances up to 1400 km are explained using ray theory and modes, in which source characteristics, refraction, scattering at the ice surface, and bottom effects are important.&lt;br /&gt;

A BBC film crew has captured footage of killer whales working together to create waves to wash their vulnerable prey into the water.&lt;br /&gt;
The predators targeted a weddell seal that was resting on a small ice floe, sweeping it off the ice to where they could attack it.&lt;br /&gt;
Scientists who worked with the film crew said the footage revealed new insights into killer whale ecology.&lt;br /&gt;

&lt;br /&gt;
Information from the DIY microplastic experimentation and conversations with researchers from Bergen&#039;s Marine Institute, alongside sound recordings from the hydrophone field trips, informed the design of a prototype Coral Empathy Device. The device obliterates the visual, employing sound, pressure, texture and smell to translate messages of anthropogenic marine intervention between the experience of coral in the Norwegian waters and the experience of humans on terra. Liquid to air, coral to human, the Coral Empathy Device prototype is an experiment in interspecies empathy.&lt;br /&gt;

&lt;br /&gt;
&lt;br /&gt;
When we look up to sky and look into the space and wonder about what is up there, we&lt;br /&gt;
&lt;br /&gt;
sometime forget, that there is a lot still also to explore on the planet we live.&lt;br /&gt;
&lt;br /&gt;
We know more about the space than we know about the world’s seas and oceans,&lt;br /&gt;
&lt;br /&gt;
especially about the sound perception underwater.&lt;br /&gt;
&lt;br /&gt;
People are not so aware of the vibrant underwater acoustic of sounds of the deepness of&lt;br /&gt;
&lt;br /&gt;
ocean, except for the crash of a wave against a land. Whales, shrimp, seals, dolphins, and a&lt;br /&gt;
&lt;br /&gt;
variety of other creatures of the deep live in a watery acoustical ­ sonic environment. The&lt;br /&gt;
&lt;br /&gt;
arrival of steamships and other human­made interventions into the ocean soundscape has&lt;br /&gt;
&lt;br /&gt;
contributed disturbing noise to this rich soundscape.&lt;br /&gt;
&lt;br /&gt;
The workshop / project encourage an inter­relationship between sound, nature, and&lt;br /&gt;
&lt;br /&gt;
society, as a starting point for the rethinking of the possible developed of nicer sonic&lt;br /&gt;
&lt;br /&gt;
environments for the animals living in the world&#039;s oceans and sea’s.&lt;br /&gt;
&lt;br /&gt;
The underwater sound pollution is the reality of recent development and industrialization&lt;br /&gt;
&lt;br /&gt;
reflecting on the sea.&lt;br /&gt;
&lt;br /&gt;
Especially the upper level of the seas ­ where there is most of the living in the seas and&lt;br /&gt;
&lt;br /&gt;
independent by the level of the sonic pollution in the sea. We would also try to research the&lt;br /&gt;
&lt;br /&gt;
deep sea level to understand what is happening there.&lt;br /&gt;
&lt;br /&gt;
World seas and oceans are presenting more than 70% of surface of Earth.&lt;br /&gt;
&lt;br /&gt;
97% of it is saltwater, 2% is fresh water in the form of ice and only the remaining 1% is&lt;br /&gt;
&lt;br /&gt;
drinking water, which is distributed around the planet very unevenly.&lt;br /&gt;
&lt;br /&gt;
The exploration of any ecosystem requires detailed study and observation. The ocean is the&lt;br /&gt;
&lt;br /&gt;
complex, challenging, and harsh environment on Earth and accessing it requires specially&lt;br /&gt;
&lt;br /&gt;
designed tools and technology. It has only been within the last 50 years that technology has&lt;br /&gt;
&lt;br /&gt;
advanced to the point that we can examine the ocean in a systematic, scientific, and non&lt;br /&gt;
&lt;br /&gt;
invasive way. Our ability to observe the ocean environment and its resident creatures has&lt;br /&gt;
&lt;br /&gt;
finally caught up with our imaginations and helping us to understand it also in the ways that&lt;br /&gt;
&lt;br /&gt;
we did not imagine them before.&lt;br /&gt;
&lt;br /&gt;
“&#039;&#039;Already back at the renaissance 1490 Leonardo da Vinci observed how the sound of ships&lt;br /&gt;
&lt;br /&gt;
travelled long distances underwater. The sound of ships in the 15th century included the&lt;br /&gt;
&lt;br /&gt;
noise of rudders and rigging, oars and the handling of cargo. Seafaring, while not in its&lt;br /&gt;
&lt;br /&gt;
infancy, was a “life driven” technology; the power of wind and human muscle generated the&lt;br /&gt;
&lt;br /&gt;
only anthropogenic noises in the sea. Over the next 400 years, acoustic technology at sea&lt;br /&gt;
&lt;br /&gt;
involved innovations such as underwater bells and whistling buoys on submerged rocks and&lt;br /&gt;
&lt;br /&gt;
reefs to warn navigators and captains away from marine hazards. With the advent of steam&lt;br /&gt;
&lt;br /&gt;
powered engines, the quality and level of noise began to shift dramatically. With the ability to&lt;br /&gt;
&lt;br /&gt;
navigate to, and develop the far reaches of the globe, the use of dynamite and diesel driven&lt;br /&gt;
&lt;br /&gt;
pile drivers began transforming the soundscape of coastal waters worldwide. Once the&lt;br /&gt;
&lt;br /&gt;
mechanization of seafaring and coastal civil engineering took hold, ocean noise began&lt;br /&gt;
&lt;br /&gt;
increasing exponentially&#039;&#039;” * (from the Soundscape The Journal of Acoustic Ecology​) and&lt;br /&gt;
&lt;br /&gt;
it started to overtake also the sound scape environment of the animals.&lt;br /&gt;

Marine Life&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
The sounds produced by marine animals are many and varied. Marine mammals, such as&lt;br /&gt;
&lt;br /&gt;
blue whales and harbor porpoise, produce sounds over a wide frequency range, from less&lt;br /&gt;
&lt;br /&gt;
than 10 Hz to over 100,000 Hz, depending on the species of marine mammal. Many fish,&lt;br /&gt;
&lt;br /&gt;
such as the oyster toadfish and plainfin midshipman, and some marine invertebrates, such&lt;br /&gt;
&lt;br /&gt;
as snapping shrimp, also produce sounds. Marine animals use sound to obtain detailed&lt;br /&gt;
&lt;br /&gt;
information about their surroundings. They rely on sound to communicate, navigate, and&lt;br /&gt;
&lt;br /&gt;
feed. Marine mammals, such as dolphins, use sound to locate and identify objects such as&lt;br /&gt;
&lt;br /&gt;
food, obstacles, and other whales. By emitting clicks, or short pulses of sound, and listening&lt;br /&gt;
&lt;br /&gt;
to the echo, dolphins can detect individual prey and navigate around objects underwater.&lt;br /&gt;

&#039;&#039;&#039;Salt-Water Fish Extinction Seen By 2048&#039;&#039;&#039;&lt;br /&gt;
The apocalypse has a new date: 2048.&lt;br /&gt;
&lt;br /&gt;
That&#039;s when the world&#039;s oceans will be empty of fish, predicts an international team of ecologists and economists. The cause: the disappearance of species due to overfishing, pollution, habitat loss, and climate change.&lt;br /&gt;
&lt;br /&gt;
The study by Boris Worm, PhD, of Dalhousie University in Halifax, Nova Scotia, -- with colleagues in the U.K., U.S., Sweden, and Panama -- was an effort to understand what this loss of ocean species might mean to the world.&lt;br /&gt;
&lt;br /&gt;
The researchers analyzed several different kinds of data. Even to these ecology-minded scientists, the results were an unpleasant surprise.&lt;br /&gt;

&#039;&#039;&#039;Cnidaria ­ jellyfish hearing under the water&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
At present there is still a dearth of research and understanding about how Cnidaria—with&lt;br /&gt;
&lt;br /&gt;
their ancient evolutionary history— actually perceive and adapt to their environment through&lt;br /&gt;
&lt;br /&gt;
acoustic energy and vibration, and how this has enabled them to survive over the eons&lt;br /&gt;
&lt;br /&gt;
despite their ‘simplicity.’&lt;br /&gt;
&lt;br /&gt;
Marine mammal calls can actually increase ambient noise levels by 20­25 underwater dB in&lt;br /&gt;
&lt;br /&gt;
some locations at certain times of year. Blue and fin whales produce low­frequency moans&lt;br /&gt;
&lt;br /&gt;
at frequencies of 10­25 Hz with estimated source levels of up to 190 underwater dB at 1 m.&lt;br /&gt;
&lt;br /&gt;
The ambient noise levels at frequencies of 17­20 Hz increase off coastal California during&lt;br /&gt;
&lt;br /&gt;
the fall and winter months due to blue and fin whale calls.&lt;br /&gt;

&lt;br /&gt;
&#039;&#039;&#039;Animal Sound Perception and Production Modes&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
From the preceding it is clear that many sea animals use sound in a variety of ways. Some&lt;br /&gt;
&lt;br /&gt;
animals use sound passively, others actively. Passive use of sound occurs when the animal&lt;br /&gt;
&lt;br /&gt;
does not create the sound that it senses, but responds to environmental and ambient&lt;br /&gt;
&lt;br /&gt;
sounds. These uses include: 1. Detection of predators. 2. Location and detection of prey. 3.&lt;br /&gt;
&lt;br /&gt;
Proximity perception of co­species in school, raft or colony. 4. Navigation—either local or&lt;br /&gt;
&lt;br /&gt;
global. 5. Perception of changing environmental conditions such as seismic movement, tides&lt;br /&gt;
&lt;br /&gt;
and currents. 6. Detection of food sources and feeding of other animals. 7. “Acoustic&lt;br /&gt;
&lt;br /&gt;
illumination” akin to daylight vision. Active use of sound occurs when the animal creates a&lt;br /&gt;
&lt;br /&gt;
sound to interact with their environment or other animals in it. Active uses include: 1. Sonic&lt;br /&gt;
&lt;br /&gt;
communication with co­species for breeding. 2. Sonic communication with co­species for&lt;br /&gt;
&lt;br /&gt;
feeding, including notification and guidance of others to food sources. 3. Territorial and&lt;br /&gt;
&lt;br /&gt;
social relations. 4. Echolocation. 5. Stunning and apprehending prey. 6. Alarm calls used to&lt;br /&gt;
&lt;br /&gt;
notify other creatures of the approach of enemies. 7. Long distance navigation and mapping.&lt;br /&gt;
&lt;br /&gt;
8. Use of sound as a defense against predators. 9. Use of sound when seized by a predator&lt;br /&gt;
&lt;br /&gt;
(perhaps to startle the predator).&lt;br /&gt;

Some results of a four‐year experimental study of sound propagation in the Arctic are presented and interpreted. The duration, form, and intensity of waves received at distances up to 1400 km are explained using ray theory and modes, in which source characteristics, refraction, scattering at the ice surface, and bottom effects are important.&lt;br /&gt;

A BBC film crew has captured footage of killer whales working together to create waves to wash their vulnerable prey into the water.&lt;br /&gt;
The predators targeted a weddell seal that was resting on a small ice floe, sweeping it off the ice to where they could attack it.&lt;br /&gt;
Scientists who worked with the film crew said the footage revealed new insights into killer whale ecology.&lt;br /&gt;
The team filmed the sequence for the BBC documentary Frozen Planet&lt;br /&gt;

&lt;br /&gt;
Information from the DIY microplastic experimentation and conversations with researchers from Bergen&#039;s Marine Institute, alongside sound recordings from the hydrophone field trips, informed the design of a prototype Coral Empathy Device. The device obliterates the visual, employing sound, pressure, texture and smell to translate messages of anthropogenic marine intervention between the experience of coral in the Norwegian waters and the experience of humans on terra. Liquid to air, coral to human, the Coral Empathy Device prototype is an experiment in interspecies empathy. &lt;br /&gt;

&lt;br /&gt;
&lt;br /&gt;
When we look up to sky and look into the space and wonder about what is up there, we&lt;br /&gt;
&lt;br /&gt;
sometime forget, that there is a lot still also to explore on the planet we live.&lt;br /&gt;
&lt;br /&gt;
We know more about the space than we know about the world’s seas and oceans,&lt;br /&gt;
&lt;br /&gt;
especially about the sound perception underwater.&lt;br /&gt;
&lt;br /&gt;
People are not so aware of the vibrant underwater acoustic of sounds of the deepness of&lt;br /&gt;
&lt;br /&gt;
ocean, except for the crash of a wave against a land. Whales, shrimp, seals, dolphins, and a&lt;br /&gt;
&lt;br /&gt;
variety of other creatures of the deep live in a watery acoustical ­ sonic environment. The&lt;br /&gt;
&lt;br /&gt;
arrival of steamships and other human­made interventions into the ocean soundscape has&lt;br /&gt;
&lt;br /&gt;
contributed disturbing noise to this rich soundscape.&lt;br /&gt;
&lt;br /&gt;
The workshop / project encourage an inter­relationship between sound, nature, and&lt;br /&gt;
&lt;br /&gt;
society, as a starting point for the rethinking of the possible developed of nicer sonic&lt;br /&gt;
&lt;br /&gt;
environments for the animals living in the world&#039;s oceans and sea’s.&lt;br /&gt;
&lt;br /&gt;
The underwater sound pollution is the reality of recent development and industrialization&lt;br /&gt;
&lt;br /&gt;
reflecting on the sea.&lt;br /&gt;
&lt;br /&gt;
Especially the upper level of the seas ­ where there is most of the living in the seas and&lt;br /&gt;
&lt;br /&gt;
independent by the level of the sonic pollution in the sea. We would also try to research the&lt;br /&gt;
&lt;br /&gt;
deep sea level to understand what is happening there.&lt;br /&gt;
&lt;br /&gt;
World seas and oceans are presenting more than 70% of surface of Earth.&lt;br /&gt;
&lt;br /&gt;
97% of it is saltwater, 2% is fresh water in the form of ice and only the remaining 1% is&lt;br /&gt;
&lt;br /&gt;
drinking water, which is distributed around the planet very unevenly.&lt;br /&gt;
&lt;br /&gt;
The exploration of any ecosystem requires detailed study and observation. The ocean is the&lt;br /&gt;
&lt;br /&gt;
complex, challenging, and harsh environment on Earth and accessing it requires specially&lt;br /&gt;
&lt;br /&gt;
designed tools and technology. It has only been within the last 50 years that technology has&lt;br /&gt;
&lt;br /&gt;
advanced to the point that we can examine the ocean in a systematic, scientific, and non&lt;br /&gt;
&lt;br /&gt;
invasive way. Our ability to observe the ocean environment and its resident creatures has&lt;br /&gt;
&lt;br /&gt;
finally caught up with our imaginations and helping us to understand it also in the ways that&lt;br /&gt;
&lt;br /&gt;
we did not imagine them before.&lt;br /&gt;
&lt;br /&gt;
“&#039;&#039;Already back at the renaissance 1490 Leonardo da Vinci observed how the sound of ships&lt;br /&gt;
&lt;br /&gt;
travelled long distances underwater. The sound of ships in the 15th century included the&lt;br /&gt;
&lt;br /&gt;
noise of rudders and rigging, oars and the handling of cargo. Seafaring, while not in its&lt;br /&gt;
&lt;br /&gt;
infancy, was a “life driven” technology; the power of wind and human muscle generated the&lt;br /&gt;
&lt;br /&gt;
only anthropogenic noises in the sea. Over the next 400 years, acoustic technology at sea&lt;br /&gt;
&lt;br /&gt;
involved innovations such as underwater bells and whistling buoys on submerged rocks and&lt;br /&gt;
&lt;br /&gt;
reefs to warn navigators and captains away from marine hazards. With the advent of steam&lt;br /&gt;
&lt;br /&gt;
powered engines, the quality and level of noise began to shift dramatically. With the ability to&lt;br /&gt;
&lt;br /&gt;
navigate to, and develop the far reaches of the globe, the use of dynamite and diesel driven&lt;br /&gt;
&lt;br /&gt;
pile drivers began transforming the soundscape of coastal waters worldwide. Once the&lt;br /&gt;
&lt;br /&gt;
mechanization of seafaring and coastal civil engineering took hold, ocean noise began&lt;br /&gt;
&lt;br /&gt;
increasing exponentially&#039;&#039;” * (from the Soundscape The Journal of Acoustic Ecology​) and&lt;br /&gt;
&lt;br /&gt;
it started to overtake also the sound scape environment of the animals.&lt;br /&gt;

&lt;br /&gt;
The sounds produced by marine animals are many and varied. Marine mammals, such as&lt;br /&gt;
&lt;br /&gt;
blue whales and harbor porpoise, produce sounds over a wide frequency range, from less&lt;br /&gt;
&lt;br /&gt;
than 10 Hz to over 100,000 Hz, depending on the species of marine mammal. Many fish,&lt;br /&gt;
&lt;br /&gt;
such as the oyster toadfish and plainfin midshipman, and some marine invertebrates, such&lt;br /&gt;
&lt;br /&gt;
as snapping shrimp, also produce sounds. Marine animals use sound to obtain detailed&lt;br /&gt;
&lt;br /&gt;
information about their surroundings. They rely on sound to communicate, navigate, and&lt;br /&gt;
&lt;br /&gt;
feed. Marine mammals, such as dolphins, use sound to locate and identify objects such as&lt;br /&gt;
&lt;br /&gt;
food, obstacles, and other whales. By emitting clicks, or short pulses of sound, and listening&lt;br /&gt;
&lt;br /&gt;
to the echo, dolphins can detect individual prey and navigate around objects underwater.&lt;br /&gt;

&#039;&#039;&#039;Salt-Water Fish Extinction Seen By 2048&#039;&#039;&#039;&lt;br /&gt;
The apocalypse has a new date: 2048.&lt;br /&gt;
&lt;br /&gt;
That&#039;s when the world&#039;s oceans will be empty of fish, predicts an international team of ecologists and economists. The cause: the disappearance of species due to overfishing, pollution, habitat loss, and climate change.&lt;br /&gt;
&lt;br /&gt;
The study by Boris Worm, PhD, of Dalhousie University in Halifax, Nova Scotia, -- with colleagues in the U.K., U.S., Sweden, and Panama -- was an effort to understand what this loss of ocean species might mean to the world.&lt;br /&gt;
&lt;br /&gt;
The researchers analyzed several different kinds of data. Even to these ecology-minded scientists, the results were an unpleasant surprise.&lt;br /&gt;

&#039;&#039;&#039;Cnidaria ­ jellyfish hearing under the water&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
At present there is still a dearth of research and understanding about how Cnidaria—with&lt;br /&gt;
&lt;br /&gt;
their ancient evolutionary history— actually perceive and adapt to their environment through&lt;br /&gt;
&lt;br /&gt;
acoustic energy and vibration, and how this has enabled them to survive over the eons&lt;br /&gt;
&lt;br /&gt;
despite their ‘simplicity.’&lt;br /&gt;
&lt;br /&gt;
Marine mammal calls can actually increase ambient noise levels by 20­25 underwater dB in&lt;br /&gt;

some locations at certain times of year. Blue and fin whales produce low­frequency moans&lt;br /&gt;
&lt;br /&gt;
at frequencies of 10­25 Hz with estimated source levels of up to 190 underwater dB at 1 m.&lt;br /&gt;
&lt;br /&gt;
The ambient noise levels at frequencies of 17­20 Hz increase off coastal California during&lt;br /&gt;
&lt;br /&gt;
the fall and winter months due to blue and fin whale calls.&lt;br /&gt;

&#039;&#039;&#039;Animal Sound Perception and Production Modes&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
From the preceding it is clear that many sea animals use sound in a variety of ways. Some&lt;br /&gt;
&lt;br /&gt;
animals use sound passively, others actively. Passive use of sound occurs when the animal&lt;br /&gt;
&lt;br /&gt;
does not create the sound that it senses, but responds to environmental and ambient&lt;br /&gt;
&lt;br /&gt;
sounds. These uses include: 1. Detection of predators. 2. Location and detection of prey. 3.&lt;br /&gt;
&lt;br /&gt;
Proximity perception of co­species in school, raft or colony. 4. Navigation—either local or&lt;br /&gt;
&lt;br /&gt;
global. 5. Perception of changing environmental conditions such as seismic movement, tides&lt;br /&gt;
&lt;br /&gt;
and currents. 6. Detection of food sources and feeding of other animals. 7. “Acoustic&lt;br /&gt;
&lt;br /&gt;
illumination” akin to daylight vision. Active use of sound occurs when the animal creates a&lt;br /&gt;
&lt;br /&gt;
sound to interact with their environment or other animals in it. Active uses include: 1. Sonic&lt;br /&gt;
&lt;br /&gt;
communication with co­species for breeding. 2. Sonic communication with co­species for&lt;br /&gt;
&lt;br /&gt;
feeding, including notification and guidance of others to food sources. 3. Territorial and&lt;br /&gt;
&lt;br /&gt;
social relations. 4. Echolocation. 5. Stunning and apprehending prey. 6. Alarm calls used to&lt;br /&gt;
&lt;br /&gt;
notify other creatures of the approach of enemies. 7. Long distance navigation and mapping.&lt;br /&gt;
&lt;br /&gt;
8. Use of sound as a defense against predators. 9. Use of sound when seized by a predator&lt;br /&gt;
&lt;br /&gt;
(perhaps to startle the predator).&lt;br /&gt;

by H. W. Marsh and R. H. Mellen&lt;br /&gt;
Some results of a four‐year experimental study of sound propagation in the Arctic are presented and interpreted. The duration, form, and intensity of waves received at distances up to 1400 km are explained using ray theory and modes, in which source characteristics, refraction, scattering at the ice surface, and bottom effects are important.&lt;br /&gt;

A recent study published in the journal Geology shared some surprising findings: the icy landscape of Svalbard, Norway was once home to an ancient tropical forest. A group of researchers from Cardiff University found fossilized tree stumps belonging to lycopsids, a tropical tree, during the course of field work in the area.&lt;br /&gt;

A BBC film crew has captured footage of killer whales working together to create waves to wash their vulnerable prey into the water.&lt;br /&gt;
The predators targeted a weddell seal that was resting on a small ice floe, sweeping it off the ice to where they could attack it.&lt;br /&gt;
Scientists who worked with the film crew said the footage revealed new insights into killer whale ecology.&lt;br /&gt;

&lt;br /&gt;
&lt;br /&gt;
When we look up to sky and look into the space and wonder about what is up there, we&lt;br /&gt;
&lt;br /&gt;
sometime forget, that there is a lot still also to explore on the planet we live.&lt;br /&gt;
&lt;br /&gt;
We know more about the space than we know about the world’s seas and oceans,&lt;br /&gt;
&lt;br /&gt;
especially about the sound perception underwater.&lt;br /&gt;
&lt;br /&gt;
People are not so aware of the vibrant underwater acoustic of sounds of the deepness of&lt;br /&gt;
&lt;br /&gt;
ocean, except for the crash of a wave against a land. Whales, shrimp, seals, dolphins, and a&lt;br /&gt;
&lt;br /&gt;
variety of other creatures of the deep live in a watery acoustical ­ sonic environment. The&lt;br /&gt;
&lt;br /&gt;
arrival of steamships and other human­made interventions into the ocean soundscape has&lt;br /&gt;
&lt;br /&gt;
contributed disturbing noise to this rich soundscape.&lt;br /&gt;
&lt;br /&gt;
The workshop / project encourage an inter­relationship between sound, nature, and&lt;br /&gt;
&lt;br /&gt;
society, as a starting point for the rethinking of the possible developed of nicer sonic&lt;br /&gt;
&lt;br /&gt;
environments for the animals living in the world&#039;s oceans and sea’s.&lt;br /&gt;
&lt;br /&gt;
The underwater sound pollution is the reality of recent development and industrialization&lt;br /&gt;
&lt;br /&gt;
reflecting on the sea.&lt;br /&gt;
&lt;br /&gt;
Especially the upper level of the seas ­ where there is most of the living in the seas and&lt;br /&gt;
&lt;br /&gt;
independent by the level of the sonic pollution in the sea. We would also try to research the&lt;br /&gt;
&lt;br /&gt;
deep sea level to understand what is happening there.&lt;br /&gt;
&lt;br /&gt;
World seas and oceans are presenting more than 70% of surface of Earth.&lt;br /&gt;
&lt;br /&gt;
97% of it is saltwater, 2% is fresh water in the form of ice and only the remaining 1% is&lt;br /&gt;
&lt;br /&gt;
drinking water, which is distributed around the planet very unevenly.&lt;br /&gt;
&lt;br /&gt;
The exploration of any ecosystem requires detailed study and observation. The ocean is the&lt;br /&gt;
&lt;br /&gt;
complex, challenging, and harsh environment on Earth and accessing it requires specially&lt;br /&gt;
&lt;br /&gt;
designed tools and technology. It has only been within the last 50 years that technology has&lt;br /&gt;
&lt;br /&gt;
advanced to the point that we can examine the ocean in a systematic, scientific, and non&lt;br /&gt;

invasive way. Our ability to observe the ocean environment and its resident creatures has&lt;br /&gt;
&lt;br /&gt;
finally caught up with our imaginations and helping us to understand it also in the ways that&lt;br /&gt;
&lt;br /&gt;
we did not imagine them before.&lt;br /&gt;
&lt;br /&gt;
“&#039;&#039;Already back at the renaissance 1490 Leonardo da Vinci observed how the sound of ships&lt;br /&gt;
&lt;br /&gt;
travelled long distances underwater. The sound of ships in the 15th century included the&lt;br /&gt;
&lt;br /&gt;
noise of rudders and rigging, oars and the handling of cargo. Seafaring, while not in its&lt;br /&gt;
&lt;br /&gt;
infancy, was a “life driven” technology; the power of wind and human muscle generated the&lt;br /&gt;
&lt;br /&gt;
only anthropogenic noises in the sea. Over the next 400 years, acoustic technology at sea&lt;br /&gt;

involved innovations such as underwater bells and whistling buoys on submerged rocks and&lt;br /&gt;
&lt;br /&gt;
reefs to warn navigators and captains away from marine hazards. With the advent of steam&lt;br /&gt;
&lt;br /&gt;
powered engines, the quality and level of noise began to shift dramatically. With the ability to&lt;br /&gt;
&lt;br /&gt;
navigate to, and develop the far reaches of the globe, the use of dynamite and diesel driven&lt;br /&gt;
&lt;br /&gt;
pile drivers began transforming the soundscape of coastal waters worldwide. Once the&lt;br /&gt;
&lt;br /&gt;
mechanization of seafaring and coastal civil engineering took hold, ocean noise began&lt;br /&gt;
&lt;br /&gt;
increasing exponentially&#039;&#039;” * (from the Soundscape The Journal of Acoustic Ecology​) and&lt;br /&gt;
&lt;br /&gt;
it started to overtake also the sound scape environment of the animals.&lt;br /&gt;

Marine Life&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
The sounds produced by marine animals are many and varied. Marine mammals, such as&lt;br /&gt;
&lt;br /&gt;
blue whales and harbor porpoise, produce sounds over a wide frequency range, from less&lt;br /&gt;
&lt;br /&gt;
than 10 Hz to over 100,000 Hz, depending on the species of marine mammal. Many fish,&lt;br /&gt;
&lt;br /&gt;
such as the oyster toadfish and plainfin midshipman, and some marine invertebrates, such&lt;br /&gt;
&lt;br /&gt;
as snapping shrimp, also produce sounds. Marine animals use sound to obtain detailed&lt;br /&gt;
&lt;br /&gt;
information about their surroundings. They rely on sound to communicate, navigate, and&lt;br /&gt;
&lt;br /&gt;
feed. Marine mammals, such as dolphins, use sound to locate and identify objects such as&lt;br /&gt;
&lt;br /&gt;
food, obstacles, and other whales. By emitting clicks, or short pulses of sound, and listening&lt;br /&gt;
&lt;br /&gt;
to the echo, dolphins can detect individual prey and navigate around objects underwater.&lt;br /&gt;

&#039;&#039;&#039;Salt-Water Fish Extinction Seen By 2048&#039;&#039;&#039;&lt;br /&gt;
The apocalypse has a new date: 2048.&lt;br /&gt;
&lt;br /&gt;
That&#039;s when the world&#039;s oceans will be empty of fish, predicts an international team of ecologists and economists. The cause: the disappearance of species due to overfishing, pollution, habitat loss, and climate change.&lt;br /&gt;
&lt;br /&gt;
The study by Boris Worm, PhD, of Dalhousie University in Halifax, Nova Scotia, -- with colleagues in the U.K., U.S., Sweden, and Panama -- was an effort to understand what this loss of ocean species might mean to the world.&lt;br /&gt;
&lt;br /&gt;
The researchers analyzed several different kinds of data. Even to these ecology-minded scientists, the results were an unpleasant surprise.&lt;br /&gt;

&#039;&#039;&#039;Cnidaria ­ jellyfish hearing under the water&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
At present there is still a dearth of research and understanding about how Cnidaria—with&lt;br /&gt;
&lt;br /&gt;
their ancient evolutionary history— actually perceive and adapt to their environment through&lt;br /&gt;
&lt;br /&gt;
acoustic energy and vibration, and how this has enabled them to survive over the eons&lt;br /&gt;
&lt;br /&gt;
despite their ‘simplicity.’&lt;br /&gt;
&lt;br /&gt;
Marine mammal calls can actually increase ambient noise levels by 20­25 underwater dB in&lt;br /&gt;
&lt;br /&gt;
some locations at certain times of year. Blue and fin whales produce low­frequency moans&lt;br /&gt;
&lt;br /&gt;
at frequencies of 10­25 Hz with estimated source levels of up to 190 underwater dB at 1 m.&lt;br /&gt;
&lt;br /&gt;
The ambient noise levels at frequencies of 17­20 Hz increase off coastal California during&lt;br /&gt;
&lt;br /&gt;
the fall and winter months due to blue and fin whale calls.&lt;br /&gt;

&#039;&#039;&#039;Animal Sound Perception and Production Modes&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
From the preceding it is clear that many sea animals use sound in a variety of ways. Some&lt;br /&gt;
&lt;br /&gt;
animals use sound passively, others actively. Passive use of sound occurs when the animal&lt;br /&gt;
&lt;br /&gt;
does not create the sound that it senses, but responds to environmental and ambient&lt;br /&gt;
&lt;br /&gt;
sounds. These uses include: 1. Detection of predators. 2. Location and detection of prey. 3.&lt;br /&gt;
&lt;br /&gt;
Proximity perception of co­species in school, raft or colony. 4. Navigation—either local or&lt;br /&gt;
&lt;br /&gt;
global. 5. Perception of changing environmental conditions such as seismic movement, tides&lt;br /&gt;
&lt;br /&gt;
and currents. 6. Detection of food sources and feeding of other animals. 7. “Acoustic&lt;br /&gt;
&lt;br /&gt;
illumination” akin to daylight vision. Active use of sound occurs when the animal creates a&lt;br /&gt;
&lt;br /&gt;
sound to interact with their environment or other animals in it. Active uses include: 1. Sonic&lt;br /&gt;
&lt;br /&gt;
communication with co­species for breeding. 2. Sonic communication with co­species for&lt;br /&gt;
&lt;br /&gt;
feeding, including notification and guidance of others to food sources. 3. Territorial and&lt;br /&gt;
&lt;br /&gt;
social relations. 4. Echolocation. 5. Stunning and apprehending prey. 6. Alarm calls used to&lt;br /&gt;
&lt;br /&gt;
notify other creatures of the approach of enemies. 7. Long distance navigation and mapping.&lt;br /&gt;
&lt;br /&gt;
8. Use of sound as a defense against predators. 9. Use of sound when seized by a predator&lt;br /&gt;
&lt;br /&gt;
(perhaps to startle the predator).&lt;br /&gt;

Some results of a four‐year experimental study of sound propagation in the Arctic are presented and interpreted. The duration, form, and intensity of waves received at distances up to 1400 km are explained using ray theory and modes, in which source characteristics, refraction, scattering at the ice surface, and bottom effects are important.&lt;br /&gt;

A BBC film crew has captured footage of killer whales working together to create waves to wash their vulnerable prey into the water.&lt;br /&gt;
The predators targeted a weddell seal that was resting on a small ice floe, sweeping it off the ice to where they could attack it.&lt;br /&gt;
Scientists who worked with the film crew said the footage revealed new insights into killer whale ecology.&lt;br /&gt;

When we look up to sky and look into the space and wonder about what is up there, we&lt;br /&gt;
&lt;br /&gt;
sometime forget, that there is a lot still also to explore on the planet we live.&lt;br /&gt;
&lt;br /&gt;
We know more about the space than we know about the world’s seas and oceans,&lt;br /&gt;
&lt;br /&gt;
especially about the sound perception underwater.&lt;br /&gt;
&lt;br /&gt;
People are not so aware of the vibrant underwater acoustic of sounds of the deepness of&lt;br /&gt;
&lt;br /&gt;
ocean, except for the crash of a wave against a land. Whales, shrimp, seals, dolphins, and a&lt;br /&gt;
&lt;br /&gt;
variety of other creatures of the deep live in a watery acoustical ­ sonic environment. The&lt;br /&gt;
&lt;br /&gt;
arrival of steamships and other human­made interventions into the ocean soundscape has&lt;br /&gt;
&lt;br /&gt;
contributed disturbing noise to this rich soundscape.&lt;br /&gt;
&lt;br /&gt;
The workshop / project encourage an inter­relationship between sound, nature, and&lt;br /&gt;
&lt;br /&gt;
society, as a starting point for the rethinking of the possible developed of nicer sonic&lt;br /&gt;
&lt;br /&gt;
environments for the animals living in the world&#039;s oceans and sea’s.&lt;br /&gt;
&lt;br /&gt;
The underwater sound pollution is the reality of recent development and industrialization&lt;br /&gt;
&lt;br /&gt;
reflecting on the sea.&lt;br /&gt;
&lt;br /&gt;
Especially the upper level of the seas ­ where there is most of the living in the seas and&lt;br /&gt;
&lt;br /&gt;
independent by the level of the sonic pollution in the sea. We would also try to research the&lt;br /&gt;
&lt;br /&gt;

World seas and oceans are presenting more than 70% of surface of Earth.&lt;br /&gt;
&lt;br /&gt;
97% of it is saltwater, 2% is fresh water in the form of ice and only the remaining 1% is&lt;br /&gt;
&lt;br /&gt;
drinking water, which is distributed around the planet very unevenly.&lt;br /&gt;
&lt;br /&gt;
The exploration of any ecosystem requires detailed study and observation. The ocean is the&lt;br /&gt;
&lt;br /&gt;
complex, challenging, and harsh environment on Earth and accessing it requires specially&lt;br /&gt;
&lt;br /&gt;
designed tools and technology. It has only been within the last 50 years that technology has&lt;br /&gt;
&lt;br /&gt;
advanced to the point that we can examine the ocean in a systematic, scientific, and non&lt;br /&gt;

invasive way. Our ability to observe the ocean environment and its resident creatures has&lt;br /&gt;
&lt;br /&gt;
finally caught up with our imaginations and helping us to understand it also in the ways that&lt;br /&gt;
&lt;br /&gt;
we did not imagine them before.&lt;br /&gt;
&lt;br /&gt;
“&#039;&#039;Already back at the renaissance 1490 Leonardo da Vinci observed how the sound of ships&lt;br /&gt;
&lt;br /&gt;
travelled long distances underwater. The sound of ships in the 15th century included the&lt;br /&gt;
&lt;br /&gt;
noise of rudders and rigging, oars and the handling of cargo. Seafaring, while not in its&lt;br /&gt;
&lt;br /&gt;
infancy, was a “life driven” technology; the power of wind and human muscle generated the&lt;br /&gt;
&lt;br /&gt;
only anthropogenic noises in the sea. Over the next 400 years, acoustic technology at sea&lt;br /&gt;
&lt;br /&gt;
involved innovations such as underwater bells and whistling buoys on submerged rocks and&lt;br /&gt;
&lt;br /&gt;
reefs to warn navigators and captains away from marine hazards. With the advent of steam&lt;br /&gt;
&lt;br /&gt;
powered engines, the quality and level of noise began to shift dramatically. With the ability to&lt;br /&gt;
&lt;br /&gt;
navigate to, and develop the far reaches of the globe, the use of dynamite and diesel driven&lt;br /&gt;
&lt;br /&gt;
pile drivers began transforming the soundscape of coastal waters worldwide. Once the&lt;br /&gt;
&lt;br /&gt;
mechanization of seafaring and coastal civil engineering took hold, ocean noise began&lt;br /&gt;
&lt;br /&gt;
increasing exponentially&#039;&#039;” * (from the Soundscape The Journal of Acoustic Ecology​) and&lt;br /&gt;
&lt;br /&gt;
it started to overtake also the sound scape environment of the animals.&lt;br /&gt;

Marine Life&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
The sounds produced by marine animals are many and varied. Marine mammals, such as&lt;br /&gt;
&lt;br /&gt;
blue whales and harbor porpoise, produce sounds over a wide frequency range, from less&lt;br /&gt;
&lt;br /&gt;
than 10 Hz to over 100,000 Hz, depending on the species of marine mammal. Many fish,&lt;br /&gt;
&lt;br /&gt;
such as the oyster toadfish and plainfin midshipman, and some marine invertebrates, such&lt;br /&gt;
&lt;br /&gt;
as snapping shrimp, also produce sounds. Marine animals use sound to obtain detailed&lt;br /&gt;
&lt;br /&gt;
information about their surroundings. They rely on sound to communicate, navigate, and&lt;br /&gt;
&lt;br /&gt;
feed. Marine mammals, such as dolphins, use sound to locate and identify objects such as&lt;br /&gt;
&lt;br /&gt;
food, obstacles, and other whales. By emitting clicks, or short pulses of sound, and listening&lt;br /&gt;
&lt;br /&gt;
to the echo, dolphins can detect individual prey and navigate around objects underwater.&lt;br /&gt;

&#039;&#039;&#039;Salt-Water Fish Extinction Seen By 2048&#039;&#039;&#039;&lt;br /&gt;
The apocalypse has a new date: 2048.&lt;br /&gt;
&lt;br /&gt;
That&#039;s when the world&#039;s oceans will be empty of fish, predicts an international team of ecologists and economists. The cause: the disappearance of species due to overfishing, pollution, habitat loss, and climate change.&lt;br /&gt;
&lt;br /&gt;
The study by Boris Worm, PhD, of Dalhousie University in Halifax, Nova Scotia, -- with colleagues in the U.K., U.S., Sweden, and Panama -- was an effort to understand what this loss of ocean species might mean to the world.&lt;br /&gt;
&lt;br /&gt;
The researchers analyzed several different kinds of data. Even to these ecology-minded scientists, the results were an unpleasant surprise.&lt;br /&gt;

&#039;&#039;&#039;Cnidaria ­ jellyfish hearing under the water&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
At present there is still a dearth of research and understanding about how Cnidaria—with&lt;br /&gt;
&lt;br /&gt;
their ancient evolutionary history— actually perceive and adapt to their environment through&lt;br /&gt;
&lt;br /&gt;
acoustic energy and vibration, and how this has enabled them to survive over the eons&lt;br /&gt;
&lt;br /&gt;
despite their ‘simplicity.’&lt;br /&gt;
&lt;br /&gt;
Marine mammal calls can actually increase ambient noise levels by 20­25 underwater dB in&lt;br /&gt;
&lt;br /&gt;
some locations at certain times of year. Blue and fin whales produce low­frequency moans&lt;br /&gt;
&lt;br /&gt;
at frequencies of 10­25 Hz with estimated source levels of up to 190 underwater dB at 1 m.&lt;br /&gt;
&lt;br /&gt;
The ambient noise levels at frequencies of 17­20 Hz increase off coastal California during&lt;br /&gt;
&lt;br /&gt;
the fall and winter months due to blue and fin whale calls.&lt;br /&gt;

&#039;&#039;&#039;Animal Sound Perception and Production Modes&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
From the preceding it is clear that many sea animals use sound in a variety of ways. Some&lt;br /&gt;
&lt;br /&gt;
animals use sound passively, others actively. Passive use of sound occurs when the animal&lt;br /&gt;
&lt;br /&gt;
does not create the sound that it senses, but responds to environmental and ambient&lt;br /&gt;
&lt;br /&gt;
sounds. These uses include: 1. Detection of predators. 2. Location and detection of prey. 3.&lt;br /&gt;
&lt;br /&gt;
Proximity perception of co­species in school, raft or colony. 4. Navigation—either local or&lt;br /&gt;
&lt;br /&gt;
global. 5. Perception of changing environmental conditions such as seismic movement, tides&lt;br /&gt;
&lt;br /&gt;
and currents. 6. Detection of food sources and feeding of other animals. 7. “Acoustic&lt;br /&gt;
&lt;br /&gt;
illumination” akin to daylight vision. Active use of sound occurs when the animal creates a&lt;br /&gt;
&lt;br /&gt;
sound to interact with their environment or other animals in it. Active uses include: 1. Sonic&lt;br /&gt;
&lt;br /&gt;
communication with co­species for breeding. 2. Sonic communication with co­species for&lt;br /&gt;
&lt;br /&gt;
feeding, including notification and guidance of others to food sources. 3. Territorial and&lt;br /&gt;
&lt;br /&gt;
social relations. 4. Echolocation. 5. Stunning and apprehending prey. 6. Alarm calls used to&lt;br /&gt;
&lt;br /&gt;
notify other creatures of the approach of enemies. 7. Long distance navigation and mapping.&lt;br /&gt;
&lt;br /&gt;
8. Use of sound as a defense against predators. 9. Use of sound when seized by a predator&lt;br /&gt;
&lt;br /&gt;
(perhaps to startle the predator).&lt;br /&gt;

Some results of a four‐year experimental study of sound propagation in the Arctic are presented and interpreted. The duration, form, and intensity of waves received at distances up to 1400 km are explained using ray theory and modes, in which source characteristics, refraction, scattering at the ice surface, and bottom effects are important.&lt;br /&gt;

A BBC film crew has captured footage of killer whales working together to create waves to wash their vulnerable prey into the water.&lt;br /&gt;
The predators targeted a weddell seal that was resting on a small ice floe, sweeping it off the ice to where they could attack it.&lt;br /&gt;
Scientists who worked with the film crew said the footage revealed new insights into killer whale ecology.&lt;br /&gt;

&lt;br /&gt;
&lt;br /&gt;
When we look up to sky and look into the space and wonder about what is up there, we&lt;br /&gt;
&lt;br /&gt;
sometime forget, that there is a lot still also to explore on the planet we live.&lt;br /&gt;
&lt;br /&gt;
We know more about the space than we know about the world’s seas and oceans,&lt;br /&gt;
&lt;br /&gt;
especially about the sound perception underwater.&lt;br /&gt;
&lt;br /&gt;
People are not so aware of the vibrant underwater acoustic of sounds of the deepness of&lt;br /&gt;
&lt;br /&gt;
ocean, except for the crash of a wave against a land. Whales, shrimp, seals, dolphins, and a&lt;br /&gt;
&lt;br /&gt;
variety of other creatures of the deep live in a watery acoustical ­ sonic environment. The&lt;br /&gt;
&lt;br /&gt;
arrival of steamships and other human­made interventions into the ocean soundscape has&lt;br /&gt;
&lt;br /&gt;
contributed disturbing noise to this rich soundscape.&lt;br /&gt;
&lt;br /&gt;
The workshop / project encourage an inter­relationship between sound, nature, and&lt;br /&gt;
&lt;br /&gt;
society, as a starting point for the rethinking of the possible developed of nicer sonic&lt;br /&gt;
&lt;br /&gt;
environments for the animals living in the world&#039;s oceans and sea’s.&lt;br /&gt;
&lt;br /&gt;
The underwater sound pollution is the reality of recent development and industrialization&lt;br /&gt;
&lt;br /&gt;
reflecting on the sea.&lt;br /&gt;
&lt;br /&gt;
Especially the upper level of the seas ­ where there is most of the living in the seas and&lt;br /&gt;
&lt;br /&gt;
independent by the level of the sonic pollution in the sea. We would also try to research the&lt;br /&gt;
&lt;br /&gt;
deep sea level to understand what is happening there.&lt;br /&gt;
&lt;br /&gt;
World seas and oceans are presenting more than 70% of surface of Earth.&lt;br /&gt;
&lt;br /&gt;
97% of it is saltwater, 2% is fresh water in the form of ice and only the remaining 1% is&lt;br /&gt;
&lt;br /&gt;
drinking water, which is distributed around the planet very unevenly.&lt;br /&gt;
&lt;br /&gt;
The exploration of any ecosystem requires detailed study and observation. The ocean is the&lt;br /&gt;
&lt;br /&gt;
complex, challenging, and harsh environment on Earth and accessing it requires specially&lt;br /&gt;
&lt;br /&gt;
designed tools and technology. It has only been within the last 50 years that technology has&lt;br /&gt;
&lt;br /&gt;
advanced to the point that we can examine the ocean in a systematic, scientific, and non&lt;br /&gt;

invasive way. Our ability to observe the ocean environment and its resident creatures has&lt;br /&gt;
&lt;br /&gt;
finally caught up with our imaginations and helping us to understand it also in the ways that&lt;br /&gt;
&lt;br /&gt;
we did not imagine them before.&lt;br /&gt;
&lt;br /&gt;
“&#039;&#039;Already back at the renaissance 1490 Leonardo da Vinci observed how the sound of ships&lt;br /&gt;
&lt;br /&gt;
travelled long distances underwater. The sound of ships in the 15th century included the&lt;br /&gt;
&lt;br /&gt;
noise of rudders and rigging, oars and the handling of cargo. Seafaring, while not in its&lt;br /&gt;
&lt;br /&gt;
infancy, was a “life driven” technology; the power of wind and human muscle generated the&lt;br /&gt;
&lt;br /&gt;
only anthropogenic noises in the sea. Over the next 400 years, acoustic technology at sea&lt;br /&gt;
&lt;br /&gt;
involved innovations such as underwater bells and whistling buoys on submerged rocks and&lt;br /&gt;
&lt;br /&gt;
reefs to warn navigators and captains away from marine hazards. With the advent of steam&lt;br /&gt;
&lt;br /&gt;
powered engines, the quality and level of noise began to shift dramatically. With the ability to&lt;br /&gt;
&lt;br /&gt;
navigate to, and develop the far reaches of the globe, the use of dynamite and diesel driven&lt;br /&gt;
&lt;br /&gt;
pile drivers began transforming the soundscape of coastal waters worldwide. Once the&lt;br /&gt;
&lt;br /&gt;
mechanization of seafaring and coastal civil engineering took hold, ocean noise began&lt;br /&gt;
&lt;br /&gt;
increasing exponentially&#039;&#039;” * (from the Soundscape The Journal of Acoustic Ecology​) and&lt;br /&gt;
&lt;br /&gt;
it started to overtake also the sound scape environment of the animals.&lt;br /&gt;

Marine Life&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
The sounds produced by marine animals are many and varied. Marine mammals, such as&lt;br /&gt;
&lt;br /&gt;
blue whales and harbor porpoise, produce sounds over a wide frequency range, from less&lt;br /&gt;
&lt;br /&gt;
than 10 Hz to over 100,000 Hz, depending on the species of marine mammal. Many fish,&lt;br /&gt;
&lt;br /&gt;
such as the oyster toadfish and plainfin midshipman, and some marine invertebrates, such&lt;br /&gt;
&lt;br /&gt;
as snapping shrimp, also produce sounds. Marine animals use sound to obtain detailed&lt;br /&gt;
&lt;br /&gt;
information about their surroundings. They rely on sound to communicate, navigate, and&lt;br /&gt;
&lt;br /&gt;
feed. Marine mammals, such as dolphins, use sound to locate and identify objects such as&lt;br /&gt;
&lt;br /&gt;
food, obstacles, and other whales. By emitting clicks, or short pulses of sound, and listening&lt;br /&gt;
&lt;br /&gt;
to the echo, dolphins can detect individual prey and navigate around objects underwater.&lt;br /&gt;

&#039;&#039;&#039;Salt-Water Fish Extinction Seen By 2048&#039;&#039;&#039;&lt;br /&gt;
The apocalypse has a new date: 2048.&lt;br /&gt;
&lt;br /&gt;
That&#039;s when the world&#039;s oceans will be empty of fish, predicts an international team of ecologists and economists. The cause: the disappearance of species due to overfishing, pollution, habitat loss, and climate change.&lt;br /&gt;
&lt;br /&gt;
The study by Boris Worm, PhD, of Dalhousie University in Halifax, Nova Scotia, -- with colleagues in the U.K., U.S., Sweden, and Panama -- was an effort to understand what this loss of ocean species might mean to the world.&lt;br /&gt;
&lt;br /&gt;
The researchers analyzed several different kinds of data. Even to these ecology-minded scientists, the results were an unpleasant surprise.&lt;br /&gt;

&#039;&#039;&#039;Cnidaria ­ jellyfish hearing under the water&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
At present there is still a dearth of research and understanding about how Cnidaria—with&lt;br /&gt;
&lt;br /&gt;
their ancient evolutionary history— actually perceive and adapt to their environment through&lt;br /&gt;
&lt;br /&gt;
acoustic energy and vibration, and how this has enabled them to survive over the eons&lt;br /&gt;
&lt;br /&gt;
despite their ‘simplicity.’&lt;br /&gt;
&lt;br /&gt;
Marine mammal calls can actually increase ambient noise levels by 20­25 underwater dB in&lt;br /&gt;
&lt;br /&gt;
some locations at certain times of year. Blue and fin whales produce low­frequency moans&lt;br /&gt;
&lt;br /&gt;
at frequencies of 10­25 Hz with estimated source levels of up to 190 underwater dB at 1 m.&lt;br /&gt;
&lt;br /&gt;
The ambient noise levels at frequencies of 17­20 Hz increase off coastal California during&lt;br /&gt;
&lt;br /&gt;
the fall and winter months due to blue and fin whale calls.&lt;br /&gt;

&#039;&#039;&#039;Animal Sound Perception and Production Modes&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
From the preceding it is clear that many sea animals use sound in a variety of ways. Some&lt;br /&gt;
&lt;br /&gt;
animals use sound passively, others actively. Passive use of sound occurs when the animal&lt;br /&gt;
&lt;br /&gt;
does not create the sound that it senses, but responds to environmental and ambient&lt;br /&gt;
&lt;br /&gt;
sounds. These uses include: 1. Detection of predators. 2. Location and detection of prey. 3.&lt;br /&gt;
&lt;br /&gt;
Proximity perception of co­species in school, raft or colony. 4. Navigation—either local or&lt;br /&gt;
&lt;br /&gt;
global. 5. Perception of changing environmental conditions such as seismic movement, tides&lt;br /&gt;
&lt;br /&gt;
and currents. 6. Detection of food sources and feeding of other animals. 7. “Acoustic&lt;br /&gt;
&lt;br /&gt;
illumination” akin to daylight vision. Active use of sound occurs when the animal creates a&lt;br /&gt;
&lt;br /&gt;
sound to interact with their environment or other animals in it. Active uses include: 1. Sonic&lt;br /&gt;
&lt;br /&gt;
communication with co­species for breeding. 2. Sonic communication with co­species for&lt;br /&gt;
&lt;br /&gt;
feeding, including notification and guidance of others to food sources. 3. Territorial and&lt;br /&gt;
&lt;br /&gt;
social relations. 4. Echolocation. 5. Stunning and apprehending prey. 6. Alarm calls used to&lt;br /&gt;
&lt;br /&gt;
notify other creatures of the approach of enemies. 7. Long distance navigation and mapping.&lt;br /&gt;
&lt;br /&gt;
8. Use of sound as a defense against predators. 9. Use of sound when seized by a predator&lt;br /&gt;
&lt;br /&gt;
(perhaps to startle the predator).&lt;br /&gt;

Some results of a four‐year experimental study of sound propagation in the Arctic are presented and interpreted. The duration, form, and intensity of waves received at distances up to 1400 km are explained using ray theory and modes, in which source characteristics, refraction, scattering at the ice surface, and bottom effects are important.&lt;br /&gt;

A BBC film crew has captured footage of killer whales working together to create waves to wash their vulnerable prey into the water.&lt;br /&gt;
The predators targeted a weddell seal that was resting on a small ice floe, sweeping it off the ice to where they could attack it.&lt;br /&gt;
Scientists who worked with the film crew said the footage revealed new insights into killer whale ecology.&lt;br /&gt;

&lt;br /&gt;
&lt;br /&gt;
When we look up to sky and look into the space and wonder about what is up there, we&lt;br /&gt;
&lt;br /&gt;
sometime forget, that there is a lot still also to explore on the planet we live.&lt;br /&gt;
&lt;br /&gt;
We know more about the space than we know about the world’s seas and oceans,&lt;br /&gt;
&lt;br /&gt;
especially about the sound perception underwater.&lt;br /&gt;
&lt;br /&gt;
People are not so aware of the vibrant underwater acoustic of sounds of the deepness of&lt;br /&gt;
&lt;br /&gt;
ocean, except for the crash of a wave against a land. Whales, shrimp, seals, dolphins, and a&lt;br /&gt;
&lt;br /&gt;
variety of other creatures of the deep live in a watery acoustical ­ sonic environment. The&lt;br /&gt;
&lt;br /&gt;
arrival of steamships and other human­made interventions into the ocean soundscape has&lt;br /&gt;
&lt;br /&gt;
contributed disturbing noise to this rich soundscape.&lt;br /&gt;
&lt;br /&gt;
The workshop / project encourage an inter­relationship between sound, nature, and&lt;br /&gt;
&lt;br /&gt;
society, as a starting point for the rethinking of the possible developed of nicer sonic&lt;br /&gt;
&lt;br /&gt;
environments for the animals living in the world&#039;s oceans and sea’s.&lt;br /&gt;
&lt;br /&gt;
The underwater sound pollution is the reality of recent development and industrialization&lt;br /&gt;
&lt;br /&gt;
reflecting on the sea.&lt;br /&gt;
&lt;br /&gt;
Especially the upper level of the seas ­ where there is most of the living in the seas and&lt;br /&gt;
&lt;br /&gt;
independent by the level of the sonic pollution in the sea. We would also try to research the&lt;br /&gt;
&lt;br /&gt;
deep sea level to understand what is happening there.&lt;br /&gt;
&lt;br /&gt;
World seas and oceans are presenting more than 70% of surface of Earth.&lt;br /&gt;
&lt;br /&gt;
97% of it is saltwater, 2% is fresh water in the form of ice and only the remaining 1% is&lt;br /&gt;
&lt;br /&gt;
drinking water, which is distributed around the planet very unevenly.&lt;br /&gt;
&lt;br /&gt;
The exploration of any ecosystem requires detailed study and observation. The ocean is the&lt;br /&gt;
&lt;br /&gt;
complex, challenging, and harsh environment on Earth and accessing it requires specially&lt;br /&gt;
&lt;br /&gt;
designed tools and technology. It has only been within the last 50 years that technology has&lt;br /&gt;
&lt;br /&gt;
advanced to the point that we can examine the ocean in a systematic, scientific, and non&lt;br /&gt;

invasive way. Our ability to observe the ocean environment and its resident creatures has&lt;br /&gt;
&lt;br /&gt;
finally caught up with our imaginations and helping us to understand it also in the ways that&lt;br /&gt;
&lt;br /&gt;
we did not imagine them before.&lt;br /&gt;
&lt;br /&gt;
“&#039;&#039;Already back at the renaissance 1490 Leonardo da Vinci observed how the sound of ships&lt;br /&gt;
&lt;br /&gt;
travelled long distances underwater. The sound of ships in the 15th century included the&lt;br /&gt;
&lt;br /&gt;
noise of rudders and rigging, oars and the handling of cargo. Seafaring, while not in its&lt;br /&gt;
&lt;br /&gt;
infancy, was a “life driven” technology; the power of wind and human muscle generated the&lt;br /&gt;
&lt;br /&gt;
only anthropogenic noises in the sea. Over the next 400 years, acoustic technology at sea&lt;br /&gt;
&lt;br /&gt;
involved innovations such as underwater bells and whistling buoys on submerged rocks and&lt;br /&gt;
&lt;br /&gt;
reefs to warn navigators and captains away from marine hazards. With the advent of steam&lt;br /&gt;
&lt;br /&gt;
powered engines, the quality and level of noise began to shift dramatically. With the ability to&lt;br /&gt;
&lt;br /&gt;
navigate to, and develop the far reaches of the globe, the use of dynamite and diesel driven&lt;br /&gt;
&lt;br /&gt;
pile drivers began transforming the soundscape of coastal waters worldwide. Once the&lt;br /&gt;
&lt;br /&gt;
mechanization of seafaring and coastal civil engineering took hold, ocean noise began&lt;br /&gt;
&lt;br /&gt;
increasing exponentially&#039;&#039;” * (from the Soundscape The Journal of Acoustic Ecology​) and&lt;br /&gt;
&lt;br /&gt;
it started to overtake also the sound scape environment of the animals.&lt;br /&gt;

Marine Life&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
The sounds produced by marine animals are many and varied. Marine mammals, such as&lt;br /&gt;
&lt;br /&gt;
blue whales and harbor porpoise, produce sounds over a wide frequency range, from less&lt;br /&gt;
&lt;br /&gt;
than 10 Hz to over 100,000 Hz, depending on the species of marine mammal. Many fish,&lt;br /&gt;
&lt;br /&gt;
such as the oyster toadfish and plainfin midshipman, and some marine invertebrates, such&lt;br /&gt;
&lt;br /&gt;
as snapping shrimp, also produce sounds. Marine animals use sound to obtain detailed&lt;br /&gt;
&lt;br /&gt;
information about their surroundings. They rely on sound to communicate, navigate, and&lt;br /&gt;
&lt;br /&gt;
feed. Marine mammals, such as dolphins, use sound to locate and identify objects such as&lt;br /&gt;
&lt;br /&gt;
food, obstacles, and other whales. By emitting clicks, or short pulses of sound, and listening&lt;br /&gt;
&lt;br /&gt;
to the echo, dolphins can detect individual prey and navigate around objects underwater.&lt;br /&gt;

&#039;&#039;&#039;Salt-Water Fish Extinction Seen By 2048&#039;&#039;&#039;&lt;br /&gt;
The apocalypse has a new date: 2048.&lt;br /&gt;
&lt;br /&gt;
That&#039;s when the world&#039;s oceans will be empty of fish, predicts an international team of ecologists and economists. The cause: the disappearance of species due to overfishing, pollution, habitat loss, and climate change.&lt;br /&gt;
&lt;br /&gt;
The study by Boris Worm, PhD, of Dalhousie University in Halifax, Nova Scotia, -- with colleagues in the U.K., U.S., Sweden, and Panama -- was an effort to understand what this loss of ocean species might mean to the world.&lt;br /&gt;
&lt;br /&gt;
The researchers analyzed several different kinds of data. Even to these ecology-minded scientists, the results were an unpleasant surprise.&lt;br /&gt;

&#039;&#039;&#039;Cnidaria ­ jellyfish hearing under the water&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
At present there is still a dearth of research and understanding about how Cnidaria—with&lt;br /&gt;
&lt;br /&gt;
their ancient evolutionary history— actually perceive and adapt to their environment through&lt;br /&gt;
&lt;br /&gt;
acoustic energy and vibration, and how this has enabled them to survive over the eons&lt;br /&gt;
&lt;br /&gt;
despite their ‘simplicity.’&lt;br /&gt;
&lt;br /&gt;
Marine mammal calls can actually increase ambient noise levels by 20­25 underwater dB in&lt;br /&gt;
&lt;br /&gt;
some locations at certain times of year. Blue and fin whales produce low­frequency moans&lt;br /&gt;
&lt;br /&gt;
at frequencies of 10­25 Hz with estimated source levels of up to 190 underwater dB at 1 m.&lt;br /&gt;
&lt;br /&gt;
The ambient noise levels at frequencies of 17­20 Hz increase off coastal California during&lt;br /&gt;
&lt;br /&gt;
the fall and winter months due to blue and fin whale calls.&lt;br /&gt;

&#039;&#039;&#039;Animal Sound Perception and Production Modes&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
From the preceding it is clear that many sea animals use sound in a variety of ways. Some&lt;br /&gt;
&lt;br /&gt;
animals use sound passively, others actively. Passive use of sound occurs when the animal&lt;br /&gt;
&lt;br /&gt;
does not create the sound that it senses, but responds to environmental and ambient&lt;br /&gt;
&lt;br /&gt;
sounds. These uses include: 1. Detection of predators. 2. Location and detection of prey. 3.&lt;br /&gt;
&lt;br /&gt;
Proximity perception of co­species in school, raft or colony. 4. Navigation—either local or&lt;br /&gt;
&lt;br /&gt;
global. 5. Perception of changing environmental conditions such as seismic movement, tides&lt;br /&gt;
&lt;br /&gt;
and currents. 6. Detection of food sources and feeding of other animals. 7. “Acoustic&lt;br /&gt;
&lt;br /&gt;
illumination” akin to daylight vision. Active use of sound occurs when the animal creates a&lt;br /&gt;
&lt;br /&gt;
sound to interact with their environment or other animals in it. Active uses include: 1. Sonic&lt;br /&gt;
&lt;br /&gt;
communication with co­species for breeding. 2. Sonic communication with co­species for&lt;br /&gt;
&lt;br /&gt;
feeding, including notification and guidance of others to food sources. 3. Territorial and&lt;br /&gt;
&lt;br /&gt;
social relations. 4. Echolocation. 5. Stunning and apprehending prey. 6. Alarm calls used to&lt;br /&gt;
&lt;br /&gt;
notify other creatures of the approach of enemies. 7. Long distance navigation and mapping.&lt;br /&gt;
&lt;br /&gt;
8. Use of sound as a defense against predators. 9. Use of sound when seized by a predator&lt;br /&gt;
&lt;br /&gt;
(perhaps to startle the predator).&lt;br /&gt;

Some results of a four‐year experimental study of sound propagation in the Arctic are presented and interpreted. The duration, form, and intensity of waves received at distances up to 1400 km are explained using ray theory and modes, in which source characteristics, refraction, scattering at the ice surface, and bottom effects are important.&lt;br /&gt;

&lt;br /&gt;
&lt;br /&gt;
When we look up to sky and look into the space and wonder about what is up there, we&lt;br /&gt;
&lt;br /&gt;
sometime forget, that there is a lot still also to explore on the planet we live.&lt;br /&gt;
&lt;br /&gt;
We know more about the space than we know about the world’s seas and oceans,&lt;br /&gt;
&lt;br /&gt;
especially about the sound perception underwater.&lt;br /&gt;
&lt;br /&gt;
People are not so aware of the vibrant underwater acoustic of sounds of the deepness of&lt;br /&gt;
&lt;br /&gt;
ocean, except for the crash of a wave against a land. Whales, shrimp, seals, dolphins, and a&lt;br /&gt;
&lt;br /&gt;
variety of other creatures of the deep live in a watery acoustical ­ sonic environment. The&lt;br /&gt;
&lt;br /&gt;
arrival of steamships and other human­made interventions into the ocean soundscape has&lt;br /&gt;
&lt;br /&gt;
contributed disturbing noise to this rich soundscape.&lt;br /&gt;
&lt;br /&gt;
The workshop / project encourage an inter­relationship between sound, nature, and&lt;br /&gt;
&lt;br /&gt;
society, as a starting point for the rethinking of the possible developed of nicer sonic&lt;br /&gt;
&lt;br /&gt;
environments for the animals living in the world&#039;s oceans and sea’s.&lt;br /&gt;
&lt;br /&gt;
The underwater sound pollution is the reality of recent development and industrialization&lt;br /&gt;
&lt;br /&gt;
reflecting on the sea.&lt;br /&gt;
&lt;br /&gt;
Especially the upper level of the seas ­ where there is most of the living in the seas and&lt;br /&gt;
&lt;br /&gt;
independent by the level of the sonic pollution in the sea. We would also try to research the&lt;br /&gt;
&lt;br /&gt;
deep sea level to understand what is happening there.&lt;br /&gt;
&lt;br /&gt;
World seas and oceans are presenting more than 70% of surface of Earth.&lt;br /&gt;
&lt;br /&gt;
97% of it is saltwater, 2% is fresh water in the form of ice and only the remaining 1% is&lt;br /&gt;
&lt;br /&gt;
drinking water, which is distributed around the planet very unevenly.&lt;br /&gt;
&lt;br /&gt;
The exploration of any ecosystem requires detailed study and observation. The ocean is the&lt;br /&gt;
&lt;br /&gt;
complex, challenging, and harsh environment on Earth and accessing it requires specially&lt;br /&gt;
&lt;br /&gt;
designed tools and technology. It has only been within the last 50 years that technology has&lt;br /&gt;
&lt;br /&gt;
advanced to the point that we can examine the ocean in a systematic, scientific, and non&lt;br /&gt;

invasive way. Our ability to observe the ocean environment and its resident creatures has&lt;br /&gt;
&lt;br /&gt;
finally caught up with our imaginations and helping us to understand it also in the ways that&lt;br /&gt;
&lt;br /&gt;
we did not imagine them before.&lt;br /&gt;
&lt;br /&gt;
“&#039;&#039;Already back at the renaissance 1490 Leonardo da Vinci observed how the sound of ships&lt;br /&gt;
&lt;br /&gt;
travelled long distances underwater. The sound of ships in the 15th century included the&lt;br /&gt;
&lt;br /&gt;
noise of rudders and rigging, oars and the handling of cargo. Seafaring, while not in its&lt;br /&gt;
&lt;br /&gt;
infancy, was a “life driven” technology; the power of wind and human muscle generated the&lt;br /&gt;
&lt;br /&gt;
only anthropogenic noises in the sea. Over the next 400 years, acoustic technology at sea&lt;br /&gt;
&lt;br /&gt;
involved innovations such as underwater bells and whistling buoys on submerged rocks and&lt;br /&gt;
&lt;br /&gt;
reefs to warn navigators and captains away from marine hazards. With the advent of steam&lt;br /&gt;
&lt;br /&gt;
powered engines, the quality and level of noise began to shift dramatically. With the ability to&lt;br /&gt;
&lt;br /&gt;
navigate to, and develop the far reaches of the globe, the use of dynamite and diesel driven&lt;br /&gt;
&lt;br /&gt;
pile drivers began transforming the soundscape of coastal waters worldwide. Once the&lt;br /&gt;
&lt;br /&gt;
mechanization of seafaring and coastal civil engineering took hold, ocean noise began&lt;br /&gt;
&lt;br /&gt;
increasing exponentially&#039;&#039;” * (from the Soundscape The Journal of Acoustic Ecology​) and&lt;br /&gt;
&lt;br /&gt;
it started to overtake also the sound scape environment of the animals.&lt;br /&gt;

Marine Life&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
The sounds produced by marine animals are many and varied. Marine mammals, such as&lt;br /&gt;
&lt;br /&gt;
blue whales and harbor porpoise, produce sounds over a wide frequency range, from less&lt;br /&gt;
&lt;br /&gt;
than 10 Hz to over 100,000 Hz, depending on the species of marine mammal. Many fish,&lt;br /&gt;
&lt;br /&gt;
such as the oyster toadfish and plainfin midshipman, and some marine invertebrates, such&lt;br /&gt;
&lt;br /&gt;
as snapping shrimp, also produce sounds. Marine animals use sound to obtain detailed&lt;br /&gt;
&lt;br /&gt;
information about their surroundings. They rely on sound to communicate, navigate, and&lt;br /&gt;
&lt;br /&gt;
feed. Marine mammals, such as dolphins, use sound to locate and identify objects such as&lt;br /&gt;
&lt;br /&gt;
food, obstacles, and other whales. By emitting clicks, or short pulses of sound, and listening&lt;br /&gt;
&lt;br /&gt;
to the echo, dolphins can detect individual prey and navigate around objects underwater.&lt;br /&gt;

&#039;&#039;&#039;Salt-Water Fish Extinction Seen By 2048&#039;&#039;&#039;&lt;br /&gt;
The apocalypse has a new date: 2048.&lt;br /&gt;
&lt;br /&gt;
That&#039;s when the world&#039;s oceans will be empty of fish, predicts an international team of ecologists and economists. The cause: the disappearance of species due to overfishing, pollution, habitat loss, and climate change.&lt;br /&gt;
&lt;br /&gt;
The study by Boris Worm, PhD, of Dalhousie University in Halifax, Nova Scotia, -- with colleagues in the U.K., U.S., Sweden, and Panama -- was an effort to understand what this loss of ocean species might mean to the world.&lt;br /&gt;
&lt;br /&gt;
The researchers analyzed several different kinds of data. Even to these ecology-minded scientists, the results were an unpleasant surprise.&lt;br /&gt;

&#039;&#039;&#039;Cnidaria ­ jellyfish hearing under the water&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
At present there is still a dearth of research and understanding about how Cnidaria—with&lt;br /&gt;
&lt;br /&gt;
their ancient evolutionary history— actually perceive and adapt to their environment through&lt;br /&gt;
&lt;br /&gt;
acoustic energy and vibration, and how this has enabled them to survive over the eons&lt;br /&gt;
&lt;br /&gt;
despite their ‘simplicity.’&lt;br /&gt;
&lt;br /&gt;
Marine mammal calls can actually increase ambient noise levels by 20­25 underwater dB in&lt;br /&gt;
&lt;br /&gt;
some locations at certain times of year. Blue and fin whales produce low­frequency moans&lt;br /&gt;
&lt;br /&gt;
at frequencies of 10­25 Hz with estimated source levels of up to 190 underwater dB at 1 m.&lt;br /&gt;
&lt;br /&gt;
The ambient noise levels at frequencies of 17­20 Hz increase off coastal California during&lt;br /&gt;
&lt;br /&gt;
the fall and winter months due to blue and fin whale calls.&lt;br /&gt;

&lt;br /&gt;
&#039;&#039;&#039;Animal Sound Perception and Production Modes&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
From the preceding it is clear that many sea animals use sound in a variety of ways. Some&lt;br /&gt;
&lt;br /&gt;
animals use sound passively, others actively. Passive use of sound occurs when the animal&lt;br /&gt;
&lt;br /&gt;
does not create the sound that it senses, but responds to environmental and ambient&lt;br /&gt;
&lt;br /&gt;
sounds. These uses include: 1. Detection of predators. 2. Location and detection of prey. 3.&lt;br /&gt;
&lt;br /&gt;
Proximity perception of co­species in school, raft or colony. 4. Navigation—either local or&lt;br /&gt;
&lt;br /&gt;
global. 5. Perception of changing environmental conditions such as seismic movement, tides&lt;br /&gt;
&lt;br /&gt;
and currents. 6. Detection of food sources and feeding of other animals. 7. “Acoustic&lt;br /&gt;
&lt;br /&gt;
illumination” akin to daylight vision. Active use of sound occurs when the animal creates a&lt;br /&gt;
&lt;br /&gt;
sound to interact with their environment or other animals in it. Active uses include: 1. Sonic&lt;br /&gt;
&lt;br /&gt;
communication with co­species for breeding. 2. Sonic communication with co­species for&lt;br /&gt;
&lt;br /&gt;
feeding, including notification and guidance of others to food sources. 3. Territorial and&lt;br /&gt;
&lt;br /&gt;
social relations. 4. Echolocation. 5. Stunning and apprehending prey. 6. Alarm calls used to&lt;br /&gt;
&lt;br /&gt;
notify other creatures of the approach of enemies. 7. Long distance navigation and mapping.&lt;br /&gt;
&lt;br /&gt;
8. Use of sound as a defense against predators. 9. Use of sound when seized by a predator&lt;br /&gt;
&lt;br /&gt;
(perhaps to startle the predator).&lt;br /&gt;

Some results of a four‐year experimental study of sound propagation in the Arctic are presented and interpreted. The duration, form, and intensity of waves received at distances up to 1400 km are explained using ray theory and modes, in which source characteristics, refraction, scattering at the ice surface, and bottom effects are important.&lt;br /&gt;

A BBC film crew has captured footage of killer whales working together to create waves to wash their vulnerable prey into the water.&lt;br /&gt;
The predators targeted a weddell seal that was resting on a small ice floe, sweeping it off the ice to where they could attack it.&lt;br /&gt;
Scientists who worked with the film crew said the footage revealed new insights into killer whale ecology.&lt;br /&gt;

&lt;br /&gt;
&lt;br /&gt;
When we look up to sky and look into the space and wonder about what is up there, we&lt;br /&gt;
&lt;br /&gt;
sometime forget, that there is a lot still also to explore on the planet we live.&lt;br /&gt;
&lt;br /&gt;
We know more about the space than we know about the world’s seas and oceans,&lt;br /&gt;
&lt;br /&gt;
especially about the sound perception underwater.&lt;br /&gt;
&lt;br /&gt;
People are not so aware of the vibrant underwater acoustic of sounds of the deepness of&lt;br /&gt;
&lt;br /&gt;
ocean, except for the crash of a wave against a land. Whales, shrimp, seals, dolphins, and a&lt;br /&gt;
&lt;br /&gt;
variety of other creatures of the deep live in a watery acoustical ­ sonic environment. The&lt;br /&gt;
&lt;br /&gt;
arrival of steamships and other human­made interventions into the ocean soundscape has&lt;br /&gt;
&lt;br /&gt;
contributed disturbing noise to this rich soundscape.&lt;br /&gt;
&lt;br /&gt;
The workshop / project encourage an inter­relationship between sound, nature, and&lt;br /&gt;
&lt;br /&gt;
society, as a starting point for the rethinking of the possible developed of nicer sonic&lt;br /&gt;
&lt;br /&gt;
environments for the animals living in the world&#039;s oceans and sea’s.&lt;br /&gt;
&lt;br /&gt;
The underwater sound pollution is the reality of recent development and industrialization&lt;br /&gt;
&lt;br /&gt;
reflecting on the sea.&lt;br /&gt;
&lt;br /&gt;
Especially the upper level of the seas ­ where there is most of the living in the seas and&lt;br /&gt;
&lt;br /&gt;
independent by the level of the sonic pollution in the sea. We would also try to research the&lt;br /&gt;
&lt;br /&gt;
deep sea level to understand what is happening there.&lt;br /&gt;
&lt;br /&gt;
World seas and oceans are presenting more than 70% of surface of Earth.&lt;br /&gt;
&lt;br /&gt;
97% of it is saltwater, 2% is fresh water in the form of ice and only the remaining 1% is&lt;br /&gt;
&lt;br /&gt;
drinking water, which is distributed around the planet very unevenly.&lt;br /&gt;
&lt;br /&gt;
The exploration of any ecosystem requires detailed study and observation. The ocean is the&lt;br /&gt;
&lt;br /&gt;
complex, challenging, and harsh environment on Earth and accessing it requires specially&lt;br /&gt;
&lt;br /&gt;
designed tools and technology. It has only been within the last 50 years that technology has&lt;br /&gt;
&lt;br /&gt;
advanced to the point that we can examine the ocean in a systematic, scientific, and non&lt;br /&gt;

invasive way. Our ability to observe the ocean environment and its resident creatures has&lt;br /&gt;
&lt;br /&gt;
finally caught up with our imaginations and helping us to understand it also in the ways that&lt;br /&gt;
&lt;br /&gt;
we did not imagine them before.&lt;br /&gt;
&lt;br /&gt;
“&#039;&#039;Already back at the renaissance 1490 Leonardo da Vinci observed how the sound of ships&lt;br /&gt;
&lt;br /&gt;
travelled long distances underwater. The sound of ships in the 15th century included the&lt;br /&gt;
&lt;br /&gt;
noise of rudders and rigging, oars and the handling of cargo. Seafaring, while not in its&lt;br /&gt;
&lt;br /&gt;
infancy, was a “life driven” technology; the power of wind and human muscle generated the&lt;br /&gt;
&lt;br /&gt;
only anthropogenic noises in the sea. Over the next 400 years, acoustic technology at sea&lt;br /&gt;
&lt;br /&gt;
involved innovations such as underwater bells and whistling buoys on submerged rocks and&lt;br /&gt;
&lt;br /&gt;
reefs to warn navigators and captains away from marine hazards. With the advent of steam&lt;br /&gt;
&lt;br /&gt;
powered engines, the quality and level of noise began to shift dramatically. With the ability to&lt;br /&gt;
&lt;br /&gt;
navigate to, and develop the far reaches of the globe, the use of dynamite and diesel driven&lt;br /&gt;
&lt;br /&gt;
pile drivers began transforming the soundscape of coastal waters worldwide. Once the&lt;br /&gt;
&lt;br /&gt;
mechanization of seafaring and coastal civil engineering took hold, ocean noise began&lt;br /&gt;
&lt;br /&gt;
increasing exponentially&#039;&#039;” * (from the Soundscape The Journal of Acoustic Ecology​) and&lt;br /&gt;

Marine Life&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
The sounds produced by marine animals are many and varied. Marine mammals, such as&lt;br /&gt;
&lt;br /&gt;
blue whales and harbor porpoise, produce sounds over a wide frequency range, from less&lt;br /&gt;
&lt;br /&gt;
than 10 Hz to over 100,000 Hz, depending on the species of marine mammal. Many fish,&lt;br /&gt;
&lt;br /&gt;
such as the oyster toadfish and plainfin midshipman, and some marine invertebrates, such&lt;br /&gt;
&lt;br /&gt;
as snapping shrimp, also produce sounds. Marine animals use sound to obtain detailed&lt;br /&gt;
&lt;br /&gt;
information about their surroundings. They rely on sound to communicate, navigate, and&lt;br /&gt;
&lt;br /&gt;
feed. Marine mammals, such as dolphins, use sound to locate and identify objects such as&lt;br /&gt;
&lt;br /&gt;
food, obstacles, and other whales. By emitting clicks, or short pulses of sound, and listening&lt;br /&gt;
&lt;br /&gt;
to the echo, dolphins can detect individual prey and navigate around objects underwater.&lt;br /&gt;

&#039;&#039;&#039;Salt-Water Fish Extinction Seen By 2048&#039;&#039;&#039;&lt;br /&gt;
The apocalypse has a new date: 2048.&lt;br /&gt;
&lt;br /&gt;
That&#039;s when the world&#039;s oceans will be empty of fish, predicts an international team of ecologists and economists. The cause: the disappearance of species due to overfishing, pollution, habitat loss, and climate change.&lt;br /&gt;
&lt;br /&gt;
The study by Boris Worm, PhD, of Dalhousie University in Halifax, Nova Scotia, -- with colleagues in the U.K., U.S., Sweden, and Panama -- was an effort to understand what this loss of ocean species might mean to the world.&lt;br /&gt;
&lt;br /&gt;
The researchers analyzed several different kinds of data. Even to these ecology-minded scientists, the results were an unpleasant surprise.&lt;br /&gt;

&#039;&#039;&#039;Cnidaria ­ jellyfish hearing under the water&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
At present there is still a dearth of research and understanding about how Cnidaria—with&lt;br /&gt;
&lt;br /&gt;
their ancient evolutionary history— actually perceive and adapt to their environment through&lt;br /&gt;
&lt;br /&gt;
acoustic energy and vibration, and how this has enabled them to survive over the eons&lt;br /&gt;
&lt;br /&gt;
despite their ‘simplicity.’&lt;br /&gt;
&lt;br /&gt;
Marine mammal calls can actually increase ambient noise levels by 20­25 underwater dB in&lt;br /&gt;
&lt;br /&gt;
some locations at certain times of year. Blue and fin whales produce low­frequency moans&lt;br /&gt;
&lt;br /&gt;
at frequencies of 10­25 Hz with estimated source levels of up to 190 underwater dB at 1 m.&lt;br /&gt;
&lt;br /&gt;
The ambient noise levels at frequencies of 17­20 Hz increase off coastal California during&lt;br /&gt;
&lt;br /&gt;
the fall and winter months due to blue and fin whale calls.&lt;br /&gt;

&lt;br /&gt;
&#039;&#039;&#039;Animal Sound Perception and Production Modes&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
From the preceding it is clear that many sea animals use sound in a variety of ways. Some&lt;br /&gt;
&lt;br /&gt;
animals use sound passively, others actively. Passive use of sound occurs when the animal&lt;br /&gt;
&lt;br /&gt;
does not create the sound that it senses, but responds to environmental and ambient&lt;br /&gt;
&lt;br /&gt;
sounds. These uses include: 1. Detection of predators. 2. Location and detection of prey. 3.&lt;br /&gt;
&lt;br /&gt;
Proximity perception of co­species in school, raft or colony. 4. Navigation—either local or&lt;br /&gt;
&lt;br /&gt;
global. 5. Perception of changing environmental conditions such as seismic movement, tides&lt;br /&gt;
&lt;br /&gt;
and currents. 6. Detection of food sources and feeding of other animals. 7. “Acoustic&lt;br /&gt;
&lt;br /&gt;
illumination” akin to daylight vision. Active use of sound occurs when the animal creates a&lt;br /&gt;
&lt;br /&gt;
sound to interact with their environment or other animals in it. Active uses include: 1. Sonic&lt;br /&gt;
&lt;br /&gt;
communication with co­species for breeding. 2. Sonic communication with co­species for&lt;br /&gt;
&lt;br /&gt;
feeding, including notification and guidance of others to food sources. 3. Territorial and&lt;br /&gt;
&lt;br /&gt;
social relations. 4. Echolocation. 5. Stunning and apprehending prey. 6. Alarm calls used to&lt;br /&gt;
&lt;br /&gt;
notify other creatures of the approach of enemies. 7. Long distance navigation and mapping.&lt;br /&gt;
&lt;br /&gt;
8. Use of sound as a defense against predators. 9. Use of sound when seized by a predator&lt;br /&gt;
&lt;br /&gt;
(perhaps to startle the predator).&lt;br /&gt;

Some results of a four‐year experimental study of sound propagation in the Arctic are presented and interpreted. The duration, form, and intensity of waves received at distances up to 1400 km are explained using ray theory and modes, in which source characteristics, refraction, scattering at the ice surface, and bottom effects are important.&lt;br /&gt;

A BBC film crew has captured footage of killer whales working together to create waves to wash their vulnerable prey into the water.&lt;br /&gt;
The predators targeted a weddell seal that was resting on a small ice floe, sweeping it off the ice to where they could attack it.&lt;br /&gt;
Scientists who worked with the film crew said the footage revealed new insights into killer whale ecology.&lt;br /&gt;

&lt;br /&gt;
When we look up to sky and look into the space and wonder about what is up there, we&lt;br /&gt;
&lt;br /&gt;
sometime forget, that there is a lot still also to explore on the planet we live.&lt;br /&gt;
&lt;br /&gt;
We know more about the space than we know about the world’s seas and oceans,&lt;br /&gt;
&lt;br /&gt;
especially about the sound perception underwater.&lt;br /&gt;
&lt;br /&gt;
People are not so aware of the vibrant underwater acoustic of sounds of the deepness of&lt;br /&gt;
&lt;br /&gt;
ocean, except for the crash of a wave against a land. Whales, shrimp, seals, dolphins, and a&lt;br /&gt;
&lt;br /&gt;
variety of other creatures of the deep live in a watery acoustical ­ sonic environment. The&lt;br /&gt;
&lt;br /&gt;
arrival of steamships and other human­made interventions into the ocean soundscape has&lt;br /&gt;
&lt;br /&gt;
contributed disturbing noise to this rich soundscape.&lt;br /&gt;
&lt;br /&gt;
The workshop / project encourage an inter­relationship between sound, nature, and&lt;br /&gt;
&lt;br /&gt;
society, as a starting point for the rethinking of the possible developed of nicer sonic&lt;br /&gt;
&lt;br /&gt;
environments for the animals living in the world&#039;s oceans and sea’s.&lt;br /&gt;
&lt;br /&gt;
The underwater sound pollution is the reality of recent development and industrialization&lt;br /&gt;
&lt;br /&gt;
reflecting on the sea.&lt;br /&gt;
&lt;br /&gt;
Especially the upper level of the seas ­ where there is most of the living in the seas and&lt;br /&gt;
&lt;br /&gt;
independent by the level of the sonic pollution in the sea. We would also try to research the&lt;br /&gt;
&lt;br /&gt;
deep sea level to understand what is happening there.&lt;br /&gt;
&lt;br /&gt;
World seas and oceans are presenting more than 70% of surface of Earth.&lt;br /&gt;
&lt;br /&gt;
97% of it is saltwater, 2% is fresh water in the form of ice and only the remaining 1% is&lt;br /&gt;
&lt;br /&gt;
drinking water, which is distributed around the planet very unevenly.&lt;br /&gt;
&lt;br /&gt;
The exploration of any ecosystem requires detailed study and observation. The ocean is the&lt;br /&gt;
&lt;br /&gt;
complex, challenging, and harsh environment on Earth and accessing it requires specially&lt;br /&gt;
&lt;br /&gt;
designed tools and technology. It has only been within the last 50 years that technology has&lt;br /&gt;
&lt;br /&gt;
advanced to the point that we can examine the ocean in a systematic, scientific, and non&lt;br /&gt;

invasive way. Our ability to observe the ocean environment and its resident creatures has&lt;br /&gt;
&lt;br /&gt;
finally caught up with our imaginations and helping us to understand it also in the ways that&lt;br /&gt;
&lt;br /&gt;
we did not imagine them before.&lt;br /&gt;
&lt;br /&gt;
“&#039;&#039;Already back at the renaissance 1490 Leonardo da Vinci observed how the sound of ships&lt;br /&gt;
&lt;br /&gt;
travelled long distances underwater. The sound of ships in the 15th century included the&lt;br /&gt;
&lt;br /&gt;
noise of rudders and rigging, oars and the handling of cargo. Seafaring, while not in its&lt;br /&gt;
&lt;br /&gt;
infancy, was a “life driven” technology; the power of wind and human muscle generated the&lt;br /&gt;
&lt;br /&gt;
only anthropogenic noises in the sea. Over the next 400 years, acoustic technology at sea&lt;br /&gt;
&lt;br /&gt;
involved innovations such as underwater bells and whistling buoys on submerged rocks and&lt;br /&gt;
&lt;br /&gt;
reefs to warn navigators and captains away from marine hazards. With the advent of steam&lt;br /&gt;
&lt;br /&gt;
powered engines, the quality and level of noise began to shift dramatically. With the ability to&lt;br /&gt;
&lt;br /&gt;
navigate to, and develop the far reaches of the globe, the use of dynamite and diesel driven&lt;br /&gt;
&lt;br /&gt;
pile drivers began transforming the soundscape of coastal waters worldwide. Once the&lt;br /&gt;
&lt;br /&gt;
mechanization of seafaring and coastal civil engineering took hold, ocean noise began&lt;br /&gt;
&lt;br /&gt;
increasing exponentially&#039;&#039;” * (from the Soundscape The Journal of Acoustic Ecology​) and&lt;br /&gt;
&lt;br /&gt;
it started to overtake also the sound scape environment of the animals.&lt;br /&gt;

Marine Life&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
The sounds produced by marine animals are many and varied. Marine mammals, such as&lt;br /&gt;
&lt;br /&gt;
blue whales and harbor porpoise, produce sounds over a wide frequency range, from less&lt;br /&gt;
&lt;br /&gt;
than 10 Hz to over 100,000 Hz, depending on the species of marine mammal. Many fish,&lt;br /&gt;
&lt;br /&gt;
such as the oyster toadfish and plainfin midshipman, and some marine invertebrates, such&lt;br /&gt;
&lt;br /&gt;
as snapping shrimp, also produce sounds. Marine animals use sound to obtain detailed&lt;br /&gt;
&lt;br /&gt;
information about their surroundings. They rely on sound to communicate, navigate, and&lt;br /&gt;
&lt;br /&gt;
feed. Marine mammals, such as dolphins, use sound to locate and identify objects such as&lt;br /&gt;
&lt;br /&gt;
food, obstacles, and other whales. By emitting clicks, or short pulses of sound, and listening&lt;br /&gt;
&lt;br /&gt;
to the echo, dolphins can detect individual prey and navigate around objects underwater.&lt;br /&gt;

&#039;&#039;&#039;Salt-Water Fish Extinction Seen By 2048&#039;&#039;&#039;&lt;br /&gt;
The apocalypse has a new date: 2048.&lt;br /&gt;
&lt;br /&gt;
That&#039;s when the world&#039;s oceans will be empty of fish, predicts an international team of ecologists and economists. The cause: the disappearance of species due to overfishing, pollution, habitat loss, and climate change.&lt;br /&gt;
&lt;br /&gt;
The study by Boris Worm, PhD, of Dalhousie University in Halifax, Nova Scotia, -- with colleagues in the U.K., U.S., Sweden, and Panama -- was an effort to understand what this loss of ocean species might mean to the world.&lt;br /&gt;
&lt;br /&gt;
The researchers analyzed several different kinds of data. Even to these ecology-minded scientists, the results were an unpleasant surprise.&lt;br /&gt;

&#039;&#039;&#039;Cnidaria ­ jellyfish hearing under the water&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
At present there is still a dearth of research and understanding about how Cnidaria—with&lt;br /&gt;
&lt;br /&gt;
their ancient evolutionary history— actually perceive and adapt to their environment through&lt;br /&gt;
&lt;br /&gt;
acoustic energy and vibration, and how this has enabled them to survive over the eons&lt;br /&gt;
&lt;br /&gt;
despite their ‘simplicity.’&lt;br /&gt;
&lt;br /&gt;
Marine mammal calls can actually increase ambient noise levels by 20­25 underwater dB in&lt;br /&gt;
&lt;br /&gt;
some locations at certain times of year. Blue and fin whales produce low­frequency moans&lt;br /&gt;
&lt;br /&gt;
at frequencies of 10­25 Hz with estimated source levels of up to 190 underwater dB at 1 m.&lt;br /&gt;
&lt;br /&gt;
The ambient noise levels at frequencies of 17­20 Hz increase off coastal California during&lt;br /&gt;
&lt;br /&gt;
the fall and winter months due to blue and fin whale calls.&lt;br /&gt;

&lt;br /&gt;
&#039;&#039;&#039;Animal Sound Perception and Production Modes&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
From the preceding it is clear that many sea animals use sound in a variety of ways. Some&lt;br /&gt;
&lt;br /&gt;
animals use sound passively, others actively. Passive use of sound occurs when the animal&lt;br /&gt;
&lt;br /&gt;
does not create the sound that it senses, but responds to environmental and ambient&lt;br /&gt;
&lt;br /&gt;
sounds. These uses include: 1. Detection of predators. 2. Location and detection of prey. 3.&lt;br /&gt;
&lt;br /&gt;
Proximity perception of co­species in school, raft or colony. 4. Navigation—either local or&lt;br /&gt;
&lt;br /&gt;
global. 5. Perception of changing environmental conditions such as seismic movement, tides&lt;br /&gt;
&lt;br /&gt;
and currents. 6. Detection of food sources and feeding of other animals. 7. “Acoustic&lt;br /&gt;
&lt;br /&gt;
illumination” akin to daylight vision. Active use of sound occurs when the animal creates a&lt;br /&gt;
&lt;br /&gt;
sound to interact with their environment or other animals in it. Active uses include: 1. Sonic&lt;br /&gt;
&lt;br /&gt;
communication with co­species for breeding. 2. Sonic communication with co­species for&lt;br /&gt;
&lt;br /&gt;
feeding, including notification and guidance of others to food sources. 3. Territorial and&lt;br /&gt;
&lt;br /&gt;
social relations. 4. Echolocation. 5. Stunning and apprehending prey. 6. Alarm calls used to&lt;br /&gt;
&lt;br /&gt;
notify other creatures of the approach of enemies. 7. Long distance navigation and mapping.&lt;br /&gt;
&lt;br /&gt;
8. Use of sound as a defense against predators. 9. Use of sound when seized by a predator&lt;br /&gt;
&lt;br /&gt;
(perhaps to startle the predator).&lt;br /&gt;

Some results of a four‐year experimental study of sound propagation in the Arctic are presented and interpreted. The duration, form, and intensity of waves received at distances up to 1400 km are explained using ray theory and modes, in which source characteristics, refraction, scattering at the ice surface, and bottom effects are important.&lt;br /&gt;

A BBC film crew has captured footage of killer whales working together to create waves to wash their vulnerable prey into the water.&lt;br /&gt;
The predators targeted a weddell seal that was resting on a small ice floe, sweeping it off the ice to where they could attack it.&lt;br /&gt;
Scientists who worked with the film crew said the footage revealed new insights into killer whale ecology.&lt;br /&gt;

&lt;br /&gt;
&lt;br /&gt;
When we look up to sky and look into the space and wonder about what is up there, we&lt;br /&gt;
&lt;br /&gt;
sometime forget, that there is a lot still also to explore on the planet we live.&lt;br /&gt;
&lt;br /&gt;
We know more about the space than we know about the world’s seas and oceans,&lt;br /&gt;
&lt;br /&gt;
especially about the sound perception underwater.&lt;br /&gt;
&lt;br /&gt;
People are not so aware of the vibrant underwater acoustic of sounds of the deepness of&lt;br /&gt;
&lt;br /&gt;
ocean, except for the crash of a wave against a land. Whales, shrimp, seals, dolphins, and a&lt;br /&gt;
&lt;br /&gt;
variety of other creatures of the deep live in a watery acoustical ­ sonic environment. The&lt;br /&gt;
&lt;br /&gt;
arrival of steamships and other human­made interventions into the ocean soundscape has&lt;br /&gt;
&lt;br /&gt;
contributed disturbing noise to this rich soundscape.&lt;br /&gt;
&lt;br /&gt;
The workshop / project encourage an inter­relationship between sound, nature, and&lt;br /&gt;
&lt;br /&gt;
society, as a starting point for the rethinking of the possible developed of nicer sonic&lt;br /&gt;
&lt;br /&gt;
environments for the animals living in the world&#039;s oceans and sea’s.&lt;br /&gt;
&lt;br /&gt;
The underwater sound pollution is the reality of recent development and industrialization&lt;br /&gt;
&lt;br /&gt;
reflecting on the sea.&lt;br /&gt;
&lt;br /&gt;
Especially the upper level of the seas ­ where there is most of the living in the seas and&lt;br /&gt;
&lt;br /&gt;
independent by the level of the sonic pollution in the sea. We would also try to research the&lt;br /&gt;
&lt;br /&gt;
deep sea level to understand what is happening there.&lt;br /&gt;
&lt;br /&gt;
World seas and oceans are presenting more than 70% of surface of Earth.&lt;br /&gt;
&lt;br /&gt;
97% of it is saltwater, 2% is fresh water in the form of ice and only the remaining 1% is&lt;br /&gt;
&lt;br /&gt;
drinking water, which is distributed around the planet very unevenly.&lt;br /&gt;
&lt;br /&gt;
The exploration of any ecosystem requires detailed study and observation. The ocean is the&lt;br /&gt;
&lt;br /&gt;
complex, challenging, and harsh environment on Earth and accessing it requires specially&lt;br /&gt;
&lt;br /&gt;
designed tools and technology. It has only been within the last 50 years that technology has&lt;br /&gt;
&lt;br /&gt;
advanced to the point that we can examine the ocean in a systematic, scientific, and non&lt;br /&gt;

invasive way. Our ability to observe the ocean environment and its resident creatures has&lt;br /&gt;
&lt;br /&gt;
finally caught up with our imaginations and helping us to understand it also in the ways that&lt;br /&gt;
&lt;br /&gt;
we did not imagine them before.&lt;br /&gt;
&lt;br /&gt;
“&#039;&#039;Already back at the renaissance 1490 Leonardo da Vinci observed how the sound of ships&lt;br /&gt;
&lt;br /&gt;
travelled long distances underwater. The sound of ships in the 15th century included the&lt;br /&gt;
&lt;br /&gt;
noise of rudders and rigging, oars and the handling of cargo. Seafaring, while not in its&lt;br /&gt;
&lt;br /&gt;
infancy, was a “life driven” technology; the power of wind and human muscle generated the&lt;br /&gt;
&lt;br /&gt;
only anthropogenic noises in the sea. Over the next 400 years, acoustic technology at sea&lt;br /&gt;
&lt;br /&gt;
involved innovations such as underwater bells and whistling buoys on submerged rocks and&lt;br /&gt;
&lt;br /&gt;
reefs to warn navigators and captains away from marine hazards. With the advent of steam&lt;br /&gt;
&lt;br /&gt;
powered engines, the quality and level of noise began to shift dramatically. With the ability to&lt;br /&gt;
&lt;br /&gt;
navigate to, and develop the far reaches of the globe, the use of dynamite and diesel driven&lt;br /&gt;
&lt;br /&gt;
pile drivers began transforming the soundscape of coastal waters worldwide. Once the&lt;br /&gt;
&lt;br /&gt;
mechanization of seafaring and coastal civil engineering took hold, ocean noise began&lt;br /&gt;
&lt;br /&gt;
increasing exponentially&#039;&#039;” * (from the Soundscape The Journal of Acoustic Ecology​) and&lt;br /&gt;
&lt;br /&gt;

Marine Life&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
The sounds produced by marine animals are many and varied. Marine mammals, such as&lt;br /&gt;
&lt;br /&gt;
blue whales and harbor porpoise, produce sounds over a wide frequency range, from less&lt;br /&gt;
&lt;br /&gt;
than 10 Hz to over 100,000 Hz, depending on the species of marine mammal. Many fish,&lt;br /&gt;
&lt;br /&gt;
such as the oyster toadfish and plainfin midshipman, and some marine invertebrates, such&lt;br /&gt;
&lt;br /&gt;
as snapping shrimp, also produce sounds. Marine animals use sound to obtain detailed&lt;br /&gt;
&lt;br /&gt;
information about their surroundings. They rely on sound to communicate, navigate, and&lt;br /&gt;
&lt;br /&gt;
feed. Marine mammals, such as dolphins, use sound to locate and identify objects such as&lt;br /&gt;
&lt;br /&gt;
food, obstacles, and other whales. By emitting clicks, or short pulses of sound, and listening&lt;br /&gt;
&lt;br /&gt;
to the echo, dolphins can detect individual prey and navigate around objects underwater.&lt;br /&gt;

&#039;&#039;&#039;Salt-Water Fish Extinction Seen By 2048&#039;&#039;&#039;&lt;br /&gt;
The apocalypse has a new date: 2048.&lt;br /&gt;
&lt;br /&gt;
That&#039;s when the world&#039;s oceans will be empty of fish, predicts an international team of ecologists and economists. The cause: the disappearance of species due to overfishing, pollution, habitat loss, and climate change.&lt;br /&gt;
&lt;br /&gt;
The study by Boris Worm, PhD, of Dalhousie University in Halifax, Nova Scotia, -- with colleagues in the U.K., U.S., Sweden, and Panama -- was an effort to understand what this loss of ocean species might mean to the world.&lt;br /&gt;
&lt;br /&gt;
The researchers analyzed several different kinds of data. Even to these ecology-minded scientists, the results were an unpleasant surprise.&lt;br /&gt;

&#039;&#039;&#039;Cnidaria ­ jellyfish hearing under the water&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
At present there is still a dearth of research and understanding about how Cnidaria—with&lt;br /&gt;
&lt;br /&gt;
their ancient evolutionary history— actually perceive and adapt to their environment through&lt;br /&gt;
&lt;br /&gt;
acoustic energy and vibration, and how this has enabled them to survive over the eons&lt;br /&gt;
&lt;br /&gt;
despite their ‘simplicity.’&lt;br /&gt;
&lt;br /&gt;
Marine mammal calls can actually increase ambient noise levels by 20­25 underwater dB in&lt;br /&gt;
&lt;br /&gt;
some locations at certain times of year. Blue and fin whales produce low­frequency moans&lt;br /&gt;
&lt;br /&gt;
at frequencies of 10­25 Hz with estimated source levels of up to 190 underwater dB at 1 m.&lt;br /&gt;
&lt;br /&gt;
The ambient noise levels at frequencies of 17­20 Hz increase off coastal California during&lt;br /&gt;
&lt;br /&gt;
the fall and winter months due to blue and fin whale calls.&lt;br /&gt;

&#039;&#039;&#039;Animal Sound Perception and Production Modes&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
From the preceding it is clear that many sea animals use sound in a variety of ways. Some&lt;br /&gt;
&lt;br /&gt;
animals use sound passively, others actively. Passive use of sound occurs when the animal&lt;br /&gt;
&lt;br /&gt;
does not create the sound that it senses, but responds to environmental and ambient&lt;br /&gt;
&lt;br /&gt;
sounds. These uses include: 1. Detection of predators. 2. Location and detection of prey. 3.&lt;br /&gt;
&lt;br /&gt;
Proximity perception of co­species in school, raft or colony. 4. Navigation—either local or&lt;br /&gt;
&lt;br /&gt;
global. 5. Perception of changing environmental conditions such as seismic movement, tides&lt;br /&gt;
&lt;br /&gt;
and currents. 6. Detection of food sources and feeding of other animals. 7. “Acoustic&lt;br /&gt;
&lt;br /&gt;
illumination” akin to daylight vision. Active use of sound occurs when the animal creates a&lt;br /&gt;
&lt;br /&gt;
sound to interact with their environment or other animals in it. Active uses include: 1. Sonic&lt;br /&gt;
&lt;br /&gt;
communication with co­species for breeding. 2. Sonic communication with co­species for&lt;br /&gt;
&lt;br /&gt;
feeding, including notification and guidance of others to food sources. 3. Territorial and&lt;br /&gt;
&lt;br /&gt;
social relations. 4. Echolocation. 5. Stunning and apprehending prey. 6. Alarm calls used to&lt;br /&gt;
&lt;br /&gt;
notify other creatures of the approach of enemies. 7. Long distance navigation and mapping.&lt;br /&gt;
&lt;br /&gt;
8. Use of sound as a defense against predators. 9. Use of sound when seized by a predator&lt;br /&gt;
&lt;br /&gt;
(perhaps to startle the predator).&lt;br /&gt;

Some results of a four‐year experimental study of sound propagation in the Arctic are presented and interpreted. The duration, form, and intensity of waves received at distances up to 1400 km are explained using ray theory and modes, in which source characteristics, refraction, scattering at the ice surface, and bottom effects are important.&lt;br /&gt;
