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.

This dataset is one table with results of tests to determine exposure of Chukchi Sea polar bears to a suite of pathogens. Results are serological tests for antibodies and tests of fecal samples for presence of parasites. Serologic assays were conducted for Toxoplasma gondii, Neospora caninum, Francisella tularensis, Coxiella burnetii, Leptospira spp., Brucella canis, Brucella abortus/suis, and canine distemper virus. Parasitology analyses were conducted for presence of Giardia cysts and Cryptospiridium oocysts in fecal samples. Polar bears were sampled on sea ice in the Chukchi Sea between mid-March and early May 1987-1994 and 2008-2017. The dataset includes relevant information about the bears that were captured...
