Data

These data comprise 505 unique geospatial raster datasets which describe persistent river ice (aufeis) occurrence within floodplains of select rivers and creeks in the 1002 Area of the Arctic National Wildlife Refuge in northern Alaska. Each raster is derived from a historical observation made by one of five Landsat satellites. Surface reflectance in the green and shortwave infrared...

This data release includes 4 child items with data regarding metabolic rate, body composition, diet, behavior, blood chemistry, stable isotope, tri-axial accelerometer, and GPS locations of polar bears (Ursus maritimus) on land, Western Hudson Bay, Canada, 2019-2022. Child Item 1: "GPS Location Data from Polar Bears (Ursus maritimus) Instrumented on Land, Western Hudson Bay, Canada, 2019...

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.

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 verifies the basis for assignment of peak-flow qualification codes in the USGS National Water Information System (NWIS; https://doi.org/10.5066/F7P55KJN)...

This data release includes 2 child items with tracking data for Bar-tailed Godwits. One of the subspecies, Limosa lapponica baueri, nests in Alaska and spends the nonbreeding season in New Zealand and eastern Australia whereas L.l.menzbieri nests in Siberia and spends the nonbreeding season in western Australia. Child Item 1: "Argos Satellite Tracking Data for Bar-tailed Godwits (Limosa...

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.

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

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 (Sfiµ1, Sfiµ4, Sfiµ9, Sfiµ10, Bcaµ10, Hhiµ2, Hhiµ5) and mtDNA control region haplotypes. The second table contains the mtDNA...

The goal of algaeClassify is to facilitate the analysis of taxonomic and functional trait data for phytoplankton.

This data package includes 2 child items with tracking data for Buff-breasted Sandpipers, a shorebird species that breeds only in Arctic Alaska and Canada, spending the winter in the grasslands of Brazil, Uruguay, and Argentina after a lengthy migration. Child Item 1: "Argos and GPS Satellite Tracking Data for Buff-breasted Sandpipers (Calidris subruficollis) - Processed Data" - Quality

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.
