About DOSITS - Discovery of Sound in the Sea - 1 views

  •  
    "The Discovery of Sound in the Sea website will introduce you to the science and uses of Sound in the Sea. There are several major sections on the site such as The Science of Sound in the Sea, People and Sound in the Sea, and Animals and Sound in the Sea. You will find the site's Audio Gallery a fascinating place to visit where you can listen to underwater sounds created by marine animals, human activities, and natural phenomena such as lightning, earthquakes, and rain. Check out the Technology Gallery and discover a variety of equipment that uses sound to investigate the ocean. Watch video interviews with scientists that study how marine animals produce and hear sounds. Investigate how scientists use underwater acoustics to track ocean currents, identify potential obstacles, and quantify fish distributions. There are also resources for many specialized audiences, including teachers, students, the media, and decision makers."

Kristine Tjøgersen - Bioluminescence - 0 views

    "Thousands of species of fireflies all blink in different patterns, not only blinking in rhythms but simultaneously performing specific flight choreographies. The timing and pattern of their flashes are unique to each species. In Bioluminescence, I translated firefly behavior data from Prof. James E. Lloyd's Studies on the Flash Communication Systems of Photinus Fireflies into an orchestral piece. Rhythmic patterns of light and insect movement provide the material for both melodic and rhythmic figures. In biology, bioluminescence is the ability of living things to produce light through biochemical processes. Most bioluminescent organisms are found in the sea. The group of marine bioluminescent organisms includes fish, bacteria, and jellyfish. Some bioluminescent organisms, including fireflies and fungi, are found on land. Bioluminescence is used by creatures to make prey, defend themselves against predators, find mates, as well as for other vital activities. Recent studies show that the number of fireflies is declining. Light pollution from human-generated light disrupts insect courtship behavior because it can only occur in the dark. The artificial extension of daylight into the night disrupts the fireflies' dark-light cycles and thus their biological behavior."

Raviv Ganchrow: In the Company of Long Waves on Vimeo - 0 views

    "SONIC ACTS Festival - The Geologic Imagination Raviv Ganchrow: In the Company of Long Waves 1 March 2015 - Paradiso, Amsterdam, the Netherlands --- The saturated spectrum of infrasound suggests that toned-down sounds don't necessarily diminish. The lowest threshold of human hearing is also the upper register of an immense sonic territory that literally interfaces landmass with oceans and skies. Raviv Ganchrow introduces the theme of extensive acoustic waves in the context of his Long-Wave Synthesis project where marine oscillations, streaking meteors, calving glaciers, gas flares and nuclear explosions coexist; where sound become so heavy it's affected by gravity; and where oscillations slow down to such an extent that they spill over into weather."

    "Oceans are a sonic symphony. Sound is essential to the survival and prosperity of marine life. But man-made ocean noise is threatening this fragile world. Sonic Sea is about protecting life in our waters from the destructive effects of oceanic noise pollution."

The Antarctic and Arctic sounds rarely heard before - BBC News - 0 views

  •  
    "What do you hear when you think of the Arctic and Antarctic? "Singing" ice, a seal that sounds like it is in space, and a seismic airgun thundering like a bomb are some of the noises released by two marine acoustic labs. The project introduces the public to 50 rarely heard sounds recorded underwater in the polar regions. It highlights how noisy oceans are becoming due to increased human activity that also disrupts sea life."
