U.S. Offshore Seismic Testing
Threatens Many Marine Species, Study Says
The proposed use of seismic air guns in the search for offshore oil and gas reserves along the U.S. East Coast could injure or kill nearly 140,000 marine animals
annually and disrupt the vital activities of other species, a new study says. The seismic testing, in which guns filled with compressed air are fired
repeatedly over deep-sea target areas to provide energy companies an image of the deposits below, would threaten marine species of all sizes, from tiny fish eggs to large whales, according to an analysis by the conservation group Oceana
. The group said that the powerful air gun blasts, which it describes as “100,000 times more intense than a jet engine,” could disturb the breathing, feeding, and mating habits for dolphins and whales and cause injury or death to endangered species such as the North Atlantic right whale. The analysis comes as the U.S. Interior Department’s Bureau of Ocean Energy Management completes an environmental study on the potential effects of seismic activities from Delaware to Florida. Oil industry officials point to other research that shows seismic testing is unlikely to threaten marine mammals.
