Movements and diving of ringed seals (Phoca hispida) in Svalbard
Seven post-moulting ringed seals (Phoca hispida) were equipped with Satellite Linked Dive Recorders in Svalbard in July 1996 to determine if ringed seals conduct long-distance post-moulting feeding excursions, and to obtain details of their diving behaviour. The transmitters were programmed to trans...
