We summarize available information on Pacific walrus haulouts from available reports, interviews with coastal residents and aviators, and personal observations of the authors. We provide this in the form of a georeferenced database that may be queried and displayed with standard geographic information system and database management software. The database contains 150 records of Pacific walrus haulouts, with a summary of basic characteristics on maximum haulout size, age-sex composition, season of use, and decade of most recent use. Citations to reports are provided as a bibliographic database.

This dataset contains a select subset of Argos and GPS locations collected by satellite data collection systems from collared adult female polar bears that were instrumented in the southern Beaufort Sea between 1985-2015.

These data are a compilation of geographically widespread observations of premature mortality in Pacific salmon across their range in Alaska in 2019. Premature mortality observations primarily spanned an area of western and southcentral Alaska that is approximately one million km2 and included all five species of Pacific salmon. Observations were obtained and compiled in a single database from four sources including reports to a citizen science reporting network (LEONetwork.org), from Alaska Department of Fish and Game's Arctic-Yukon-Kuskokwim region by community members or staff, traditional media and social media, and directed emails by the lead author. Occasional observations of species other than Pacific salmon...

This dataset contains data from the use of bioelectrical impedance analysis and deuterium injection as methods to estimate the body composition of female polar bears in the southern Beaufort Sea subpopulation. Data are provided on bioelectrical impedance resistance measures, the enrichment level of deuterium oxide that was injected and measured in blood samples, and morphological measures.
