What will happen to marine life if the government allows seismic testing, using loud airgun blasts, to search for oil and gas deep beneath the seabed along the U.S. Atlantic coast in the next few years?
The answer may be foreshadowed by the scene in Peru, where earlier this year, hundreds of dolphin carcasses washed ashore along an 85-mile stretch of beach. While the science is not definitive, one expert, Dr. Yaipan-Llanos who has been investigating the cause of the dead dolphins and has conducted 30 necropsies, claims to have seen physiological impacts that resemble what would be expected from seismic testing for oil and gas.
Dr. Yaipan-Llanos found bubbles in the organs and tissues of the dolphin carcasses. These harmful bubbles may have been caused by the disruptive impacts of an intense sound source dislodging bubbles inside the animals or the rapid ascent of the animals toward the surface after being scared.
Alternatively, some have suggested that they could be caused by the natural breakdown of the animal’s body on the beach after death. However, the freshness of some of the carcasses sampled may rule out that theory. Another alarming finding is that the middle ears ...
