Data

This data release provides a vector geospatial shapefile of river and creek segments within Dolly Varden (Salvelinus malma) habitat in the Noatak River drainage (DeCicco 1985) classified for metal impairment between 1986 and 2024. The impairment classifications were based on visual inspection of Landsat and Sentinel satellite imagery. Also provided are the satellite images (as raster...

Geologic map geodatabase depicting the surficial geology of the central Brooks Range, Alaska. Including the 250k quadrangles of Ambler River, Bettles, Chandalar, Chandler Lake, Hughes, Howard Pass, Killik River, Phillip Smith Mountains, Survey Pass, and Wiseman. Database tables include geologic linework and geologic units.

This dataset provides information on aquatic invertebrate composition from ponds (n = 16; surface area 0.02 km2) and lakes (n =16, surface area > 0.10 km2) on the central Arctic Coastal Plain of Alaska. Ponds and lakes were selected for sampling as part of a larger study of Arctic water body food webs. Details on the study area and findings are published in Laske et al. 2018 and Laske et...

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 results from three stratigraphic sections of the Hue Shale located in and adjacent to the Arctic National Wildlife Refuge in northeastern Alaska. Sample heights were measured with a tape measure in continuous successions. Zircon grains from volcanic ashes were analyzed via laser ablation at the University of California, Santa Barbara (UCSB) using a Photon Machines...

This dataset consists of one table containing whole-rock geochemistry data for 251 igneous, metamorphic, and mineralized (metasomatic) rocks from various locations across Alaska in support of mineral assessments of critical minerals and transboundary watersheds. The samples were collected mainly between 2019 and 2023, and all materials were analyzed by ALS Global, between 2019 and 2023...

This data release contains input data and results for an investigation of special conditions for peak streamflow and extreme floods for USGS streamgages in Alaska. Special conditions can include data-collection conditions, basin conditions, flood-generating mechanisms, or other information and can be critical for informing hydrologic analyses such as flood frequency analysis. The dataset...

This data package contains 1) field data and 2) predicted distributions of three species of boreal-nesting birds in interior Alaska: Lesser Yellowlegs (Tringa flavipes), Olive-sided Flycatcher (Contopus cooperi), and Rusty Blackbird (Euphagus carolinus). The data are compiled from several monitoring programs: Alaska Landbird Monitoring Survey, Alaska Off-road Point-count Program, Susitna...

This data release contains one table with gene transcription results from muscle samples collected from fish occupying freshwater in various Alaskan watersheds. Heat shock protein 70 (HSP70) results from fish included in this data release are published in a separate data release available at https://doi.org/10.5066/P13ZYKWR.

This data release includes one table of nuclear microsatellite genotypes and mitochondrial DNA haplotypes from the cytochrome b region in King Eider. This information was used to determine levels of population genetic differentiation among breeding and wintering sites of King Eiders (Somateria fischeri).

These data are in four tables relating to complete blood count (CBC), biochemistry, blood gas analysis, corticosterone, serum protein electrophoresis, and sample attribute data of adult Pacific (Gavia pacifica) and Red-throated Loons (G. stellata) breeding in northern Alaska in 2023.

These data are in one table relating to the selenium concentration (μg/g) in whole blood of adult female emperor geese (Anser canagicus) sampled on the Yukon-Kuskokwim Delta, Alaska in June 2017.
