Report: Seismic Tests on E. Coast Could Harm 140,000 Whales & Dolphins
"Nearly 140,000 whales and dolphins could be injured if the Obama administration allows energy companies to conduct seismic research aimed at identifying oil and gas along the Atlantic Coast, according to a new report issued Tuesday."
"The assessment by the conservation group Oceana shines a light on the potential casualties of seismic studies that energy companies use to map the ocean floor and the underground geology of a region.
Air guns used in the process send off pulses of sound that penetrate through the ocean and under the seafloor before bouncing back with clues about what lies below.
Along the way, Oceana said, the sound waves could devastate marine life, including some of the 500 critically endangered North Atlantic right whales estimated to still exist. Air gun blasts also could cause widespread whale displacement and disrupt loggerhead sea turtles along the Atlantic Coast, Oceana concluded."Source: FuelFix, 04/16/2013
