This legacy dataset includes digitized ground temperatures from four borehole sites in Utqiagvik, Alaska. The data were measured by scientists from the Naval Arctic Research Laboratory (NARL) on a weekly to biweekly frequency spanning 1950 to 1961. The datasets include ground temperatures at approximately 15-24 depth increments down to 60-110 ft (28-33 m) (with higher measurement...

This data release contains observational data from a breeding bird inventory using standardized point counts conducted during May-June 2005 in Kenai Fjords National Park (KEFJ), Alaska. It also includes a single survey conducted for owls on the night of 30 April 2005. Data tables include 1) survey route details, 2) survey point details, 3) survey habitat details at survey points, 4) bird...

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 grizzly bears (Ursus arctos) on the North Slope of Alaska, 2023. Child Item 1: "GPS Location Data from Grizzly Bears (Ursus arctos) Instrumented on the North Slope of Alaska, USA, 2023" Child Item 2:...

Samples from the Alaska Placer Concentrate Collection (APCC) were retrieved from the U.S. Geological Survey (USGS) National Geochemical Sample Archives and submitted for mineralogical analysis at the Colorado School of Mines. The APPC contains samples from placer mining operations throughout Alaska. The original collection contained approximately 5,000 samples that were collected by USGS...

This data release includes 3 child items with tracking data for caribou, a terrestrial mammal that ranges between the Alaska and Canada. Child Item 1: "GPS Tracking Data for Caribou (Rangifer tarandus granti) from the Denali Herd, Alaska, 2010-2018" Child Item 2: "GPS Tracking Data for Caribou (Rangifer tarandus granti) from the Fortymile Herd, Alaska, 1998-1999" Child Item 3: "GPS...

This data release comprises geochemical point analyses of magnetite by electron probe microanalyzer (EPMA) and sample imagery acquired by a combination of scanning electron, reflected light, and transmitted light microscopy. Analyzed elements include Fe, Ti, Al, Mn, Mg, V, Si, Ni, Cr, and Ca. Samples are from the Taurus porphyry Cu-Mo(-Au) deposit in the Yukon-Tanana upland of eastern...

This data release contains 54 (U-Th)/He dates acquired from detrital magnetite in stream sediments adjacent to the Taurus Porphyry Cu-Mo(-Au) deposit in eastern interior Alaska's Yukon-Tanana Upland. Measured parameters include Helium-4, Uranium-238, Thorium-232, measured grain geometry factors, and all associated analytical uncertainties. Final (U-Th)/He dates along with uncertainties...

This data release includes 2 child items with tracking data for Marbled murrelets tagged in Washington state and Alaska, 2008 and 2013. Child Item 1: "Argos Satellite Tracking Data for Marbled Murrelets (Brachyramphus marmoratus - Processed Data" -- Quality-controlled data collected from Argos satellite transmitters. Child Item 2: "Argos Satellite Tracking Data for Marbled Murrelets...

This dataset contains U-Pb isotopic data and associated ages of zircons within the lithologic framework of igneous, metaigneous, and metasedimentary rocks collected from the Seldovia quadrangle in southcentral Alaska. The samples were collected as part of geological mapping and research conducted from 2020 to 2023 and funded by the Mineral Resources Program of the U.S. Geological Survey...

Boreal Partners in Flight developed the Alaska Landbird Monitoring Survey (ALMS) primarily to monitor breeding populations of landbirds in the vast off-road areas of Alaska in conjunction with data collected from the roadside North American Breeding Bird Survey (BBS). ALMS is a collaborative program in which agencies and other entities conduct standardized surveys of breeding birds and...

Since 1993 the U.S. Geological Survey (USGS) has worked with the Alaska Department of Transportation and Public Facilities (ADOT&PF) to provide hydraulic assessments of scour for bridges throughout Alaska. As part of this effort, repeat channel cross section surveys, or channel soundings, have been collected at either the upstream or downstream side of bridges on an annual or as needed...

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.
