Submarine Sonar Responsible for 400 Dolphin Deaths On Coast of West Africa?
Hundreds of dead dolphins washed up along the shore of a popular tourist destination on Zanzibar's northern coast, and scientists on Friday ruled out poisoning.More here.
It was not immediately clear what killed the estimated 400 dolphins, whose carcasses were strewn along a 2.5-mile stretch of Nungwi, said Narriman Jidawi, a marine biologist at the Institute of Marine Science in Zanzibar.
In the United States, experts were investigating the possibility that sonar from U.S. submarines could have been responsible for a similar incident in Marathon, Fla., where 68 deep-water dolphins stranded themselves in March 2005.
And U.S. scientists on Thursday said Navy sonar may have caused a group of whales to strand themselves in Hawaii in 2004.
A U.S. Navy task force patrols the East Africa coast as part of counterterrorism operations. A Navy official was not immediately available for comment, but the service rarely comments on the location of submarines at sea.

Our oceans campaigner Richard describes how important sound is to whales and dolphins, and how underwater noise pollution, particularly from powerful military sonar equipment, may be having a powerful negative impact on these amazing creatures, even to the extent of causing their deaths.
