The U.S. Bureau of Ocean Energy Management decided Friday to turn aside six applications for permits that would allow seismic testing for fossil fuel deposits beneath the Atlantic Ocean.
BOEM, an agency of the U.S. Department of Interior, specifically cited the possibility that sonic harm might come to ocean animals as a reason for its action.
“In the present circumstances and guided by an abundance of caution, we believe that the value of obtaining the geophysical and geological information from new airgun seismic surveys in the Atlantic does not outweigh the potential risks of those surveys’ acoustic pulse impacts on marine life,” the agency’s director, Abigail Ross Hopper, said in a statement.
BOEM also pointed to the recently-finalized 2017-2022 plan for leasing mineral deposits on the nation’s outer continental shelf. That plan excludes the two regions in the Atlantic Ocean in which the seismic testing would occur.
The applicants denied permits for geological and geophysical testing included TGS, GX Technology Corp., WesternGeco LLC, CGG Services (US), Inc., Spectrum Geo, Inc., and PGS. All six entities primarily serve the oil and gas industry by assisting with exploration activities.
Geological and geophysical surveys using airguns are performed because they assist fossil fuel exploration firms to determine an area’s stratigraphy, variety and location of rocks, and geologic structure.
Airguns allow observation to a depth of several thousand meters below the ocean floor. They explode from a position behind an exploration vessel every 10-15 seconds.
BOEM had previously consulted with the National Oceanic & Atmospheric Administration, as required by the Endangered Species Act, during the course of preparing an environmental impact statement on its Atlantic seismic surveying permit program. There are several marine species in the area in which the seismic surveys would have been conducted that are on the federal list of threatened and endangered species.
“Sonic blasting causes tremendous harm to endangered whales and fish,” Michael Jasny, the director of the Marine Mammal Protection Project at Natural Resources Defense Council, said.
Jasny went on to explain that use of seismic airguns “is known to disrupt foraging and other vital behaviors in endangered whales, displace fish, and harm commercial fisheries over vast areas of the ocean.”
BOEM had previously estimated that issuance of the six permits would result in millions of incidents of harassment of whales and dolphins during a five-year period. In the case of sperm whales, it is possible that hundreds of individuals could lose their ability to hunt, navigate in the ocean, and communicate with others in the species if the seismic surveys proceeded.
BOEM has acknowledged that the airguns can cause hearing loss and death in whales and fish.
