Data

The Alaska Forage Fish Database (AFFD) is a consolidation of survey data from multiple agencies that were sampled via fishing gear and predator diets. The spatial coverage includes the Gulf of Alaska, Bering Sea, Aleutian Islands, Chukchi Sea, and Beaufort Sea. Fish species within the database include Pacific sand lance, Pacific capelin, Pacific herring, juvenile walleye pollock and...

This data package is comprised of one table with genetic data from Brant (Branta bernicla). Data include sampling location and allele sizes of 14 microsatellite loci.

This data package includes 17,014 pairs of raster geotiffs. Each pair is made up of two geotiff rasters derived from historical observations from Landsat satellites (04-09) over the Yukon, Kuskokwim, and Tanana rivers in Alaska. One raster reports estimated mid-day water surface temperature (ST) in degrees Celsius (deg_Cc). The second raster reports the surface temperature quality...

The Alaska Resource Data File (ARDF) is a database of mines, prospects, and mineral occurrences in Alaska. It contains information compiled from published and unpublished sources from industry, U.S. Bureau of Mines (BOM), U.S. Geological Survey (USGS), and other government and private sources. ARDF is not a mining claims database.

This dataset consists of sample descriptions and radiocarbon age data from coastal environments on Montague Island, Alaska, analyzed at the National Ocean Sciences Accelerator Mass Spectrometry Facility.

This dataset contains taxonomic information, counts, and lengths of macroinvertebrates collected from rivers in northwest Alaska using drift and kick nets during summer and fall 2015-2019.

These data are in three tables each reporting estimated iron mineralization within stream reaches from three arctic rivers in northwestern Alaska on select days between July-August, 1985-2022. The relative magnitude of iron mineralization was measured using a remotely sensed iron index calculated from available Level 2, Collection 2, Tier 1 Landsat Surface Reflectance products derived by...

This data package contains digital images, survey location logs and a summary tabulation from carcass survey conducted at walrus haulouts in Alaska. A summary of image collection times is provided as a tabular file.

These data were part of a pilot tracking study of three adult female caribou from the Fortymile Herd in Alaska. The dataset is comprised of two comma separated values (.csv) files. Data includes: 1) processed (i.e., erroneous locations removed) GPS locations for caribou, received once per hour for 6 months (October 1998 to April 1999), and 2) spatial, temporal, and biological attributes...

This data release includes 2 child items with tracking data for Long-billed Curlews, a shorebird species that nests in deserts and grasslands of central and western North America and spends the nonbreeding season in agriculture fields and pastures or along coastlines in California, Texas, and Mexico. Child Item 1: "Argos Satellite Tracking Data for Long-billed Curlews (Numenius...

These data include water chemistry from springs, streams, rivers, and shallow groundwater collected in the Arctic National Wildlife Refuge in northern Alaska. Chemical analyses were performed for hydrochemical parameters including field parameters, major ions, nutrients, metals, stable isotopes of water, and tritium, as well as for dissolved gases useful for determining the timescale...

These data consist of the fatty acid composition (percent of mass) of adipose tissue samples from polar bears in Alaska's southern Beaufort Sea. Fat biopsy samples were collected from polar bears that were either captured or biopsy darted along the north coast of Alaska or on offshore ice during March, April, or May from 2004 to 2016. The data also include an identification code unique...
