The Department of the Interior postponed a decision on whether to allow seismic airgun use in 300,000 square miles of ocean off the Atlantic coast. This is the third time Oceana has successfully helped delay the decision. The government’s estimates predict that seismic testing would disrupt critical behaviors like feeding, calving, and breeding for many marine creatures, including dolphins, whales, and loggerhead sea turtles. At least 138,500 dolphins and whales will be injured, or possibly killed, if airguns are allowed in the mid-Atlantic. Coastal fisheries in seven states would also be impacted, as airguns can lower catch rates between 40 and 80 percent.
