Harbor seals captured in April and May 2007 at three haul-out sites in the Pacific Northwest.

Note. Seal ID indicates female (Y) or male (B) followed by a number unique to that individual. Length represents the total number of days from tag deployment to tag failure for each animal. Standard locs per day is the mean number of filtered 1, 2 and 3 quality level locations per day for each seal. Maximum displacement is the greatest over-water distance traveled by each seal from the capture site and mean distance is the average distance between all standard locations for each seal and the capture site. Number of core areas is the number of distinct regions identified by the 50th percentile contours from kernel density estimates.
