GoM seismic blast rules relaxed

In the final weeks of President Donald Trump’s administration rules have been relaxed to allow the limited use of deep-penetration seismic blasts to search for oil and gas deposits at the bottom of the Gulf of Mexico. Seismic air gun survey technology has helped locate overlooked oil deposits, but its use can disorient or kill marine animals, from the largest, including whales and dolphins, to the microscopic ones that serve as the foundation of the GoM’s food web.
