Regional habitat utilization and time spent in eddies by adult female northern fur seals.

<p>For each satellite-tracked migratory seal, panel (A) shows number of hours spent in the Cape Blanco region (black, defined as 41.5°N to 44.5°N and east of 128.5°W), other portions of the California Current (dark gray), the Gulf of Alaska ecosystem (medium gray), and all other ecosystems (light gray). (B) The fraction of total female time spent within km of the center of mesoscale eddies as identified by Chelton et al. <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0101268#pone.0101268-Chelton1" target="_blank">[63]</a> in each ecosystem, where is each eddy's reported radial length scale. The first row displays results for the full dataset, while the second row shows results for only seals with a tracking duration >200 d.
