Military sonar has also been accused of causing wide-spread harm and death to sealife, and a case has been taken to the Supreme Court over that, but
in this specific instance, with the death of these 3,000 dolphins (after the earlier deaths of 600 in this same area), it's caused by the deep water
sonar from oil researchers.
NRDC: Lethal Sounds
The use of military sonar poses a deadly threat to whales and other marine mammals
But this contrasts sharply with how the Deep water sonar works - which is from an air gun towed at low speeds behind a survey ship and emit
high-intensity, low-frequency sound waves to find geological layers. It has been claimed it is 1,400 times louder than a jet engine underwater, and
compared to listening to dynamite for days on end.
The Bureau of Ocean Energy Management (the same guys that were guilty of accepting bribes in exchange for turning a blind eye to lax regulations in
the BP gulf oil spill) has even acknowledged how damaging this type of sonar is, asking oil explorers not to use it in the gulf during calving season
for young dolphins, but of course this was only a request. The company using the sonar in the gulf which has also resulted in dolphin deaths is Global
Geophysical Services Inc.
