Diving behaviour of adult male white whales (Delphinapterus leucas) in Svalbard, Norway
White whales (Delphinapterus leucas) in Svalbard remain near the coast much of the year, spending most of their time in front of tidewater glaciers. In this article, the diving behaviour of adult male white whales in Svalbard (N = 16) is presented based on satellite-relay data loggers that record ti...
