Summary

This data reports on the approximate locations and methods of discovery of 530 polar bear (Ursus maritimus) maternal dens observed in the Beaufort and Chukchi seas and neighboring areas between 1910 and 2018, and archived partly by the U.S. Geological Survey, Alaska Science Center, and partly by the U.S. Fish and Wildlife Service, Marine Mammals Management, in Anchorage, Alaska. Data fields include a unique and permanent USGS identifier for each record, the year when the adult would have been expected to depart the den with young, an index of whether the maternal den was confirmed or probable, coordinates of the den, substrate that each den occurred on, the agency source of each record, method of discovery of each den, method used [...]

Purpose

The data were collected on maternal denning by polar bears that use the Beaufort and Chukchi seas. The data have been used to explain polar bear maternal denning including the distribution and timing of maternal denning, the choice of denning substrates (i.e., land versus sea ice), reproductive success, changes in maternal den distribution relative to sea ice change, and (in the case of terrestrial dens) map the land forms selected by bears for maternal denning. In general, the data have been used to explain polar bear ecology and to inform management agencies (e.g., the US Fish and Wildlife Service), however, these data are available for unrestricted use by the public. The polar bear maternal den records presented here supersede an earlier version of these data (Durner and others, 2010)
