This dataset is one table with archival logger data containing measures of tri-axial acceleration and ambient temperature measured at 16 Hz in collars (Vertex Plus collar with camera option, Vectronic Aerospace GmbH, Berlin, Germany) attached to 12 grizzly bears that were instrumented on the North Slope of Alaska, USA, for 17 - 22 days in 2023.

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 dataset is one table with time-linked behavior data derived from video camera collars on polar bears on land near Churchill, Manitoba, Canada. Eighteen polar bears were equipped with video-camera collars (Vertex Plus collar with camera option, Vectronic Aerospace GmbH, Berlin, Germany) for 19 - 23 days in 2019, 2021, and 2022.

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.

This dataset includes measures collected on polar bears captured in the Chukchi and Beaufort Seas, 1981-2017 by the U.S. Geological Survey and U.S. Fish and Wildlife Service. Data collected include body length, body mass, axillary girth, skull width and tail lengths. Bears were also aged as described in the methods. For some bears, an adipose tissue sample was collected and percent lipid content was measured, percent body fat was measured via bioelectrical impedance analysis, and/or recent feeding behavior was assessed via gut palpitation or blood urea and creatinine levels, all of which are further described in the methods.

These are data collected from two types of activity sensors housed within collars deployed on female polar bears in the Chukchi and southern Beaufort Seas during the months of July through October between 1989 and 2014. Mercury tip-switches were deployed 1989 to 2009 and accelerometers were deployed 2009-2014. Activity sensor readings were related to habitats used by polar bears as described in the methods below.
