Underwater gliders will monitor North Atlantic right whales in the Gulf of St. Lawrence
The newest glider will carry a hydrophone, which can identify the calls of right whales and report their locations,,, “There is no one way to effectively determine where the whales are at any given moment when they are in the Gulf of St. Lawrence,” Fred Whoriskey said, “So we need to start blending our approaches.” Aerial surveillance is only good on sunny days with few waves, he said, adding that hydrophones mounted on fixed buoys have their limitations. “This year we are deploying gliders into the shipping channels,” he said. “They go down, listen and detect whale calls and come up to the surface periodically and broadcast information whether there are whales there or not.” >click to read< 11:25
