...On November 28th, one month ago, Reuters reported that during a 3 day span 169 whales and dolphins beached themselves in Tasmania, an island of the southern coast of mainland Australia and in New Zealand. The cause for these beachings is not known, but Bob Brown, a senator in the Australian parliament, said "sound bombing" or seismic tests of ocean floors to test for oil and gas had been carried out near the sites of the Tasmanian beachings recently.
According to Jim Cummings of the Acoustic Ecology Institute, Seismic surveys utilizing airguns have been taking place in mineral-rich areas of the world’s oceans since 1968. Among the areas that have experienced the most intense survey activity are the North Sea, the Beaufort Sea (off Alaska’s North Slope), and the Gulf of Mexico; areas around Australia and South America are also current hot-spots of activity.
The impulses created by the release of air from arrays of up to 24 airguns create low frequency sound waves powerful enough to penetrate up to 40km below the seafloor. The “source level" of these sound waves is generally over 200dB (and often 230dB or more), roughly comparable to a sound of at least 140-170dB in air.
According to the Australian Conservation Foundation, these 200dB – 230dB shots from the airguns are fired every 10 seconds or so, from 10 meters below the surface, 24 hours a day, for 2 week periods of time, weather permitting.
These types of tests are known to affect whales and dolphins, whose acute hearing and use of sonar is very sensitive.
