Haulout behaviour of High Arctic harbour seals (Phoca vitulina vitulina) in Svalbard, Norway
Haulout behaviour of harbour seals, living atthe northern limit of their distributional range on Svalbard,Norway, was investigated from June to August2000 using a combination of low-tide counts performedduring boat surveys, hourly counts through 12- or 24-hcycles at specific haulout sites, and telem...
