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