This shapefile is the official boundary of the Western Native Trout Initiative. The boundary was originally developed by the United States Fish and Wildlife Service and was updated in 2013 to reflect revisions from the Western Native Trout Initiative, a recognized Fish Habitat Partnership (FHP) of the National Fish Habitat Partnership.

This data set documents the dry mass energy density, distribution, and stomach contents of age-0 chum salmon (Oncorhynchus keta) captured in the Kuskokwim Bay estuary in May and June 2004. The analysis of this data was published in Burrill et al. 2018 (DOI :10.1007/s00300-018-2297-2.).
Alaska permafrost characterization: Borehole Nuclear Magnetic Resonance (NMR) data collected in 2021
Geophysical measurements were collected by the U.S. Geological Survey (USGS) at five sites in Interior Alaska in September 2021 for the purposes of imaging permafrost structure and quantifying variations in subsurface moisture content in relation to thaw features. Borehole nuclear magnetic resonance (NMR) data were collected at two sites in order to determine liquid water content at depth in shallow boreholes. NMR data were collected in a 2.25 m-deep borehole at the North Star golf course adjacent to one of the ERT profiles, and in another two 1.625 m-deep boreholes adjacent to Big Trail Lake where previous NMR measurements were made in 2019 and 2020.

This dataset contains X-ray diffraction (XRD) results for coal samples from the Usibelli Coal Mine and fly ash samples from the Atkinson Heat and Power Plant in Fairbanks, AK. Additionally, X-ray diffraction results from the solid phase residuals of leaching experiments with the same fly ash are reported. The leaching experiments were performed with either 18 mgea-ohm or simulated rainwater for up to 90 days and XRD was performed on solid phase residuals from sacrifical timepoints (1 hours, 2 days, 7 days, 14 days, 28 days, and 90 days).
This dataset consists of one table with annual counts from population plots of Black-legged Kittiwakes and Common Murres at two seabird nesting colonies on Gull and Chisik Islands in lower Cook Inlet, Alaska.
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 observations of the distribution of end-of-summer snow cover on approximately 3000 glaciers across Alaska and Northwest Canada. The data are provided as: (1) GeoTIFF rasters indicating the spatial extent of end-of-summer snow cover on each glacier's surface in each year (one raster per glacier per year), and (2) yearly tables with the equilibrium line altitude and the accumulation area ratio of the glaciers derived from the snow cover extent geotiffs. Snow cover was identified in Sentinel-2 imagery using a random forest algorithm trained with a manually-created validation dataset. A series of post-processing steps were used to infill missing data from terrain shadowing and cloud cover, and...
April through May (spring) and August through September (fall) locations for tule greater white-fronted geese (Anser albifrons elgasi) marked with GPS collars at Summer Lake Wildlife Area, OR in 2018 and 2019.

Locations occurring between September 11, 2020, and arrival at, or within 50 kilometers of the Summer Lake Wildlife Area stopover location also provided with elevation information and smoke concentrations derived from the experimental HRRR-Smoke model. Median predicted smoke concentrations extrapolated from ground level through 5,000 meters also provided. These data supports the following publication: Overton, C.T., Lorenz, A.A., James,...

The U.S. Geological Survey obtained measurements of channel geometry, flow velocity, and river discharge from five rivers in Alaska September 18–20, 2016, to support research on remote sensing of river discharge. The streamflow data were acquired from the Knik, Matanuska, Chena, and Salcha Rivers and Montana Creek using TeleDyne RD Instruments Acoustic Doppler Current Profilers (ADCPs), including the RioPro, StreamPro, and RiverRay models. The original *.mmt and *.pd0 format files are provided in this data release. This data release supports the following article: Legleiter, C.J., Kinzel, P.J., and Nelson, J.M., 2017, Remote measurement of river discharge using thermal particle image velocimetry (PIV) and various...
