Estimated Post-Emergence Period for Denning Polar Bears of the Chukchi and Beaufort Seas

Data Download [22KB] | Metadata | AK Science Portal | Project Site | Date Range: 1985 - 2017

These data are estimates of den emergence date, den site departure dates, and duration at den sites as well as post-emergence observations for female polar bears sampled in the southern Beaufort Sea subpopulation 1985-2016 and the Chukchi Sea subpopulation 2008-2017. The data were used to better understand the importance of time spent at the den site post-emergence. Emergence dates and departure dates were determined using collar temperature sensor data.
