Fall Movements of Belugas (Delphinapterus leucas) with Satellite-linked Transmitters in Lancaster Sound, Jones Sound, and Northern Baffin Bay

Six adult belugas, Delphinapterus leucas, (2 males, 4 females) were instrumented with satellite-linked transmitters in Croker Bay, southeastern Devon Island in the Canadian High Arctic in mid-September 1995. Some days, the animals remained close to shore along the southeastern and eastern shoreline...
