Northern fur seal foraging behavior and prey fields in the Bering Sea, Alaska during July-October 2006

These data were used by Kuhn et al. (2015) to investigate how conclusions about predator-prey relationships change with increasing temporal disparity between predator tracking periods and prey surveys. Northern fur seals (n = 20) from St. Paul Island (Alaska, USA) were equipped with satellite tracking transmitters and time-depth recorders from July to October 2006. Fur seal dive and movement metrics were examined in relation to the relative abundance of the fur seals’ primary prey, walleye pollock (Gadus chalcogrammus), reported from the annual eastern Bering Sea groundfish survey. Relationships between foraging behavior metrics and prey abundance were examined within the Bering shelf survey grid cells at three time scales: within 2 weeks of the prey survey, within 1 month, and over the northern fur seal reproductive season (>4 months).

These data were collected to determine how northern fur seals utilize habitat and prey resources so that impacts of anthropogenic and environmental influences on a population can be evaluated.

These data were used in the published analysis: Kuhn, C.E., Sterling, J.T., and T.K. Zeppelin. 2015. Linking northern fur seal behavior with prey distributions: the impact of temporal mismatch between predator studies and prey surveys. Animal Biotelemetry 3:26. doi:10.1186/s40317-015-0064-5.
