Behavior Data from Female Polar Bears (Ursus maritimus) Instrumented in the Southern Beaufort Sea with Video Camera Collars by the USGS in April 2014-2016

공공데이터포털

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.

Measurement Data of Polar Bears Captured in the Chukchi and Southern Beaufort Seas, 1981-2017

공공데이터포털

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.

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"

Denning Behavior Classifications Using Temperature Sensor Data on Collars Deployed on Polar Bears in the Southern Beaufort Sea, 1986-2013

공공데이터포털

These data include two tables. The first is average daily temperatures received via satellite transmitting collars deployed on polar bears in the southern Beaufort Sea 1986-2013. The second is denning classifications for adult female polar bears in the southern Beaufort Sea using the temperature data. Denning was classified using a control chart-based algorithm applied to the temperature data received from the collars. This method was validated by comparisons with a previous study, direct observations during flights to track collared bears, and observations of females with newborn cubs the following spring. Further information is available in the methods.

Summer Activity Sensor Data from Collars Deployed on Female Polar Bears in the Chukchi Sea 1989 to 1995 and Southern Beaufort Sea 1989 to 2014

공공데이터포털

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.
