Scientists cast doubt on seismic testing environmental mitigations in N.L.’s offshore

Jack Lawson spent part of this past summer listening for whales around Newfoundland, using recorders moored underwater to track their movements and hear what man-made sounds they may encounter. “All you can hear 24 hours a day, for months on end, every 10 seconds is the boom of a seismic array going off at various distances from our acoustic receivers, and this has made it very hard for us to detect some species, The guns make it hard for Lawson and his team’s recorders, with the technology confusing the pulsing calls of right whales with seismic activity in the distance,  DFO scientists thought they’d recorded tens of thousands of instances of right whale calls in the Flemish Pass in 2019, Lawson said. “[But] when we actually went through and manually reviewed these, none of them turned out to be real.” >click to read< 10:41
