Deep Water Sonar Causing Thousands of Dolphin Deaths
In the face of capitalism's destructive and deadly technology, Dolphins don't have a chance.
Deep water sonar is killing dolphins by the thousands
In the past four weeks along a 135 km stretch of Peruvian coastline 615 dolphins have washed ashore, dead from the effects of ships using deep water sonar. In all, over 3000 dolphins have been found dead since the beginning of summer. At the Organization for the Conservation of Aquatic Animals (ORCA), Peru's leading marine mammal protective organization, scientists say that deep water sonar is the culprit in the mass deaths. Researchers have noticed that none of the dolphins bore marks of trauma on their bodies or showed any signs of poisoning. Instead, they found damage to the dolphins' middle ear bones, a sign of decompression syndrome, which produces a violent and painful death, according to Dr. Carlos Yaipen of ORCA. "An acoustic boom...disorients the animal and produces hemmorhages which cause the animal to end up dying on the beach."
Deep water sonar is employed in the shipping industry and by oil companies in search of undersea petroleum, and the sonar bursts cause damage to animals whose communication frequencies fall in the same range.
