Southern Beaufort Sea Polar Bear Mark Recapture Data, 2000-2023

This dataset is one table with data collected and derived from polar bears sampled in Alaska from the Southern Beaufort Sea subpopulation during 2000-2023. Collected data includes individual identity, location of observation, observation type, estimated birth year, and demographic information. Data were collected from polar bears that were captured, remotely sampled using biopsy darts, non-invasively sampled using hair-snags, and observed but not sampled. The data will be used, in conjunction with similar data collected in Canada, to estimate the abundance of polar bears from the Southern Beaufort Sea and Northern Beaufort Sea subpopulations from 2001-2023.
