Metabolic Rate, Body Composition, and Blood Biochemistry Data from Polar Bears (Ursus maritimus) on Land, Western Hudson Bay, Canada, 2019-2022

This dataset is one table with time-linked behavior data derived from video camera collars on polar bears on land near Churchill, Manitoba, Canada. Eighteen polar bears were equipped with video-camera collars (Vertex Plus collar with camera option, Vectronic Aerospace GmbH, Berlin, Germany) for 19 - 23 days in 2019, 2021, and 2022.

Chemistry of Orange and Reference Streams in Northwestern Alaska

These data include water chemistry from headwater streams to large rivers that have recently turned orange and reference rivers that have not. These samples were collected in two national parks in Arctic Alaska: Kobuk Valley National Park, and Noatak National Preserve.

Selected Peak-Flow Special Conditions for USGS Streamgages in Alaska

This data package documents selected special conditions affecting the magnitude of peak flows at streamgages in Alaska. The data consist of a table of special conditions for selected peak flows and a table of data sources. This dataset resolves ambiguity introduced by historical variations in USGS National Water Information System (NWIS; peak-flow code assignment

Tracking Data for Bar-tailed Godwits (Limosa lapponica)

This metadata document describes the data contained in the "rawData" folder of this data package. This data package contains all data collected by the Argos System from 63 satellite transmitters attached to Bar-tailed Godwits on their breeding range in arctic and western Alaska, 2005-2010. Five data files are included in the "rawData" folder of this data package. Two data files (with identical con

Radiocarbon Data for Tree Ring Samples from Girdwood, Alaska

This dataset consists of sample details and radiocarbon age data of tree-ring samples collected near Girdwood, Alaska, and analyzed at the National Ocean Sciences Accelerator Mass Spectrometry Facility.

Molecular Detection and Characterization of Highly Pathogenic H5N1 Avian Influenza Viruses in Wild Birds Inhabiting Western Alaska Provides Evidence for Three Independent Viral Introductions

This data set describes three independent viral introductions of Highly pathogenic H5N1 avian influenza viruses into Alaska.

Geochemical Data from Selected Triassic Rock Samples in Northeastern Alaska

This set of data files contains analyses of samples representing Triassic units (Shublik and Ivishak Formations and Karen Creek Sandstone) in Alaska. The samples were collected from 20 outcrop localities in northeastern Alaska. The data set includes total organic carbon (TOC) and geochemical data from inductively coupled plasma-optical emission spectroscopy-mass spectroscopy (ICP-OES-MS) and porta

Harlequin Duck Genetic Data, North America, Greenland, and Iceland, 1952-2001

This data package is comprised of three tables with data from wintering Harlequin Ducks (Histrionicus histrionicus) from Alaska, British Columbia, Washington, Maine, Greenland, and Iceland. The first table contains available allele sizes for 7 microsatellite loci and mtDNA control region haplotypes. The second table contains the mtDNA control region sequences used to assign haplotypes. The third t

Tracking Data for Buff-breasted Sandpipers (Calidris subruficollis)

This metadata document describes the data contained in the "processedData" folder of this data package. This data package contains all data collected from 130 Argos and Argos-linked GPS satellite transmitters attached to Buff-breasted Sandpipers at breeding sites in Alaska, migratory stopovers in Texas, and wintering areas in Brazil, Argentina, and Uruguay, 2016-2018. The 130 deployed tags were co

Gene Transcription and Heat Shock Protein 70 Abundance in Juvenile Hatchery Reared Coho Salmon and Chinook Salmon during a Manipulative Thermal Experiment, Anchorage, Alaska 2020-2021

This dataset consists of two tables with the results from two manipulative thermal experiments with juvenile coho salmon (May 2021) and juvenile Chinook salmon (May 2020) and include 1) gene transcription results and heat shock protein 70 abundance in coho salmon and Chinook salmon and 2) water temperatures to which fish were exposed during the experiment.
