This dataset includes measures collected on polar bears captured in the Chukchi and Beaufort Seas, 1981-2017 by the U.S. Geological Survey and U.S. Fish and Wildlife Service. Data collected include body length, body mass, axillary girth, skull width and tail lengths. Bears were also aged as described in the methods. For some bears, an adipose tissue sample was collected and percent lipid content was measured, percent body fat was measured via bioelectrical impedance analysis, and/or recent feeding behavior was assessed via gut palpitation or blood urea and creatinine levels, all of which are further described in the methods. Version History: First release: July 2020 Revised: October 2024 (ver. 2.0)

This data release contains all data collected by the Argos System from 28 satellite transmitters attached to Long-billed Curlews at breeding sites in Oregon, Nevada, and Montana. Five data files are included in the "Argos Raw Data" (Child Item 2) of this data release. Two data files (with identical content) contain the raw Argos DIAG (Diagnostic) data, one in the legacy verbose ASCII format and one in a tabular Comma Separate Value (CSV) format.

This metadata document describes the data contained in the "Argos Processed Data" (Child Item 1) of this data release. This data release contains all data collected by the Argos System from 921 satellite transmitters attached to adult Pacific walruses in the Bering and Chukchi Seas, in U.S. and Russian waters, 1988-2019. The raw data were processed to accomplish two goals: flag implausible location estimates and decode raw sensor data. Very few transmitters (n=5) also carried GPS receivers. Because the GPS locations were communicated through the Argos System, a time series of Argos (Doppler) tracking data for those 5 transmitters also exists and is included. Four Comma Separate Value (CSV) tables are included in...
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 metadata document describes the data contained in the "Argos Processed Data" (Child Item 1) of this data release. This data release contains all data collected by the Argos System from 17 satellite transmitters attached to Whooper Swans at a non-breeding site in Miyagi Prefecture, Japan, 2009. The raw data were processed to accomplish two goals: flag implausible location estimates and decode raw sensor data.

This project evaluated the potential impacts of storm surges and relative sea level rise on nesting geese and eider species that commonly breed on the Yukon-Kuskokwim Delta (Y-K Delta). Habitat suitability maps for breeding waterbirds were developed to identify current waterbird breeding habitat and distributions. Short-term climate change impacts were assessed by comparing nest densities in relation to magnitude of storms that occurred in the prior fall from 2000-2013. Additionally, nest densities were modeled using random forests in relation to the time-integrated flood index (e.g., a storm specific measure accounting for both water depth and duration of flooding) for four modeled storms (2005, 2006, 2009, and...

The Yukon-Kuskokwim Delta of Alaska is a globally important region for numerous avian species including millions of migrating and nesting waterbirds. Climate change effects such as sea level rise and increased storm frequency and intensity have the potential to impact waterbird populations and breeding habitat. In order to determine the potential impacts of these climate-mediated changes, we investigated both short-term and long-term impacts of storm surges to geese and eider species that commonly breed on the Yukon-Kuskokwim Delta.To do this, we used 29 years of ground-based surveys conducted as part of the U.S. Fish and Wildlife Service’s long-term waterbird monitoring program along with flood indices modeled...
