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 to determine the position of each den, and estimated position uncertainty. Data were collected through standardized VHF aircraft surveys and satellite radio telemetry, field research activities in polar bear habitat, and anecdotal reports from other government agencies, coastal residents, and industry personnel. The polar bear maternal den records presented here supersede an earlier version of these data (Durner and others, 2010)

This dataset contains GPS and Argos locations collected by satellite-linked GPS receivers on collars attached to 5 adult female polar bears that were instrumented in the southern Beaufort Sea from April to October 2014. Three of these collars collected both GPS and Argos locations (TGW-4689H-3, Telonics Inc., Mesa, Arizona, USA), while 2 of these collars collected only GPS locations (Iridium Track M, Lotek Wireless Inc., Newmarket, Ontario, Canada).

This dataset is one table with GPS locations collected by satellite-linked GPS receivers on collars (Vertex Plus collar with camera option, Vectronic Aerospace GmbH, Berlin, Germany) attached to 20 polar bears that were instrumented on land near Churchill, Manitoba, Canada for 19 - 23 days in 2019, 2021, and 2022.

These data from satellite radio-collared adult female polar bears captured in the southern Beaufort Sea, 1985-2016 were used for testing the regional, seasonal and decadal efficacy of retrospective polar bear resource selection functions (RSF) developed for the Arctic basin and its peripheral seas (see Durner et al. 2009). The data includes the following: 1) a csv file of locations used to build a 99% minimum convex polygon study area; 2) a csv file of locations, that occurred within the study area, and were used to test RSFs; 3) a csv file of locations used to build seasonal kernel utilization distributions (95% and 50% contours) for periods 1985-1995, 1996-2006, and 2007-2016.

This data package includes 2 child items with location and activity data from adult female polar bears in the southern Beaufort Sea, April-October 2014. Child Item 1: "GPS and Argos Location Data from Adult Female Polar Bears (Ursus maritimus) in the Southern Beaufort Sea, April-October 2014" Child Item 2: "Tri-axial Accelerometer and Conductivity Sensor Data from Adult Female Polar Bears (Ursus maritimus) in the Southern Beaufort Sea, April-October 2014"

This data release contains two tables of information on polar bear distributions in the southern Beaufort Sea during spring, from 2001 to 2016. One table provides location (classified into 5 broad regions) of individual bears during the spring. The other table presents the aerial search effort by year and area.

This dataset contains archival logger data containing measures of tri-axial acceleration and conductivity for 6 female polar bears in the southern Beaufort Sea in April 2014-2016.
