Atlantic Seismic Airgun Protection Act This bill prohibits conducting geological or geophysical activities in support of oil, gas, or methane hydrate exploration and development on the Atlantic Outer Continental Shelf. Geological and geophysical activities for oil and gas exploration generally include deep penetration seismic airgun surveys, electromagnetic surveys, deep stratigraphic and shallow test drilling, and various remote-sensing methods. The geological and geophysical activities are described in a final programmatic environmental impact statement by the Bureau of Ocean Energy Management titled "Atlantic OCS Proposed Geological and Geophysical Activities, Mid-Atlantic and South Atlantic Planning Areas."
