of 108 days (range: 8 –332 days). Four seals emigrated from the NOW area. During all seasons, the seals that remained in the area spent about 90 % of the time in coastal (< 100 m deep) waters in the eastern parts of the NOW area. The total area visited by the seals during the open-water season ranged
