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.
