This data release comprises 4 datasets used to measure the field metabolic rate, body composition, foraging success, behavior, and movement patterns of 9 female polar bears on the sea ice of the Beaufort Sea in April, 2014-2016 as well as 1 dataset used to measure the energetic cost of resting in an adult female polar bear at the San Diego Zoo, San Diego, CA. Wild bears were dosed with and had their blood analyzed for oxygen-18 and deuterium concentrations, equipped with GPS-enabled satellite video camera collars with tri-axial accelerometers, and blood was measured for serum urea and creatinine levels. The bear at the San Diego Zoo had her oxygen consumption measured while resting in a metabolic chamber.
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.
