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 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 dataset includes accelerometer data collected on collars deployed on female polar bears in the southern Beaufort Sea from 2009-2016. The accelerometer was built in to collars by Telonics, Inc. and provides a single activity value of the number of seconds active per time interval of data collection. Data were collected every 15-30 minutes. GPS and ARGOs locations collected via collars were used to generate a CRAWL model, as referenced within the data set, of estimated locations that match the time frame of activity sensor data collection and are provided with this dataset. CRAWL data were also used to determine the habitat (land or sea ice) occupied by the bear at the end of the interval of activity data collection. Temperature data were used to identify denning behavior and activity during denning has been removed from this data set.

This data set is one table with observations of polar bears located during aerial surveys along the coast and barrier islands of the southern Beaufort Seas during fall, 2010-2013. Survey flights were conducted using A-Star B2 and Bell 206 helicopters at an average altitude of 300 feet AGL and an average speed of 50 miles per hour. Survey crews searched for polar bears using coastal and inland transects and over-flights of all coastal barrier islands.

This dataset contains time-linked behavior data derived from video camera collars on southern Beaufort Sea polar bears. Nine solitary female polar bears were equipped with video-camera collars (Exeye, LLC., Bristow, VA) for 8 - 11 days in April, 2014-2016.

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.
