Data

These data are in one table with measures of the external morphology and internal organ and muscle groups collected from Bar-tailed Godwits.

This dataset contains rasters and polygon shapefiles related to predicted resource use of the Porcupine Caribou Herd (PCH) during the calving (26 May-10 June) and post-calving (11-30 June) seasons in Alaska and the Yukon Territory. Resource selection was analyzed for each season using random forest models, which compared female caribou GPS collar locations (2012-2018) to available...

This data release includes 2 child items with tracking data for Whooper Swans, a Eurasian species that closely resembles Trumpeter Swanw in North America. Child Item 1: "Argos Satellite Tracking Data for Whooper Swans (Cygnus cygnus) - Processed Data" -- Quality-controlled data collected from Argos satellite transmitters. Child Item 2: "Argos Satellite Tracking Data for Whooper Swans...

This data release includes 2 child items with tracking data for Kittlitz's Murrelets, a rare seabird species that nests solitarily on the ground in barren, often alpine areas near the North Pacific and Bering Sea. Child Item 1: "Argos Satellite Tracking Data for Kittlitz's Murrelets (Brachyramphus brevirostris) - Processed Data" -- Quality-controlled data collected from Argos satellite

This data are a single table of nest records from a multi-year study of Pacific Common Eider (Somateria mollissima v-nigrum) biology that was conducted along the lower Kashunuk River, Kigigak Island, and the mouth of the Tutakoke River on the Yukon-Kuskokwim Delta from 1991-2004.

This dataset includes morphometric measurements and pregnancy / dependency status from sea otters captured or collected (experimental harvests or recovered after the Exxon Valdez Oil Spill) in Alaska, 1947-2019 by the U.S. Geological Survey (USGS) and the U.S. Fish and Wildlife Service (USFWS). Data collected include total body length, tail length, body mass, axillary girth, paw width...

This data release contains the analytical results and the evaluated source data files of a geospatial analysis for identifying areas in Alaska that may have potential for sediment-hosted Pb-Zn (lead-zinc) deposits. The spatial analysis is based on queries of statewide source datasets Alaska Geochemical Database (AGDB3), Alaska Resource Data File (ARDF), and Alaska Geologic Map (SIM3340)...

This data release includes 2 child items with tracking data for Whimbrels, a shorebird found throughout tundra and boreal habitats of Alaska during the summer and winters along the coasts of the continental U.S., and central and South America. Child Item 1: "Argos Satellite Tracking Data for Whimbrels (Numenius phaeopus) - Processed Data" -- Quality-controlled data collected from Argos...

This dataset provides information on the identity and number of insects that emerged from thaw pond basins on the central Arctic Coastal Plain, Alaska, during the summer growing season in 2012 and 2013. Collections were made using passive floating emergence traps in pond centers and margins from four types of ponds: low centered polygons, troughs, small coalescent, and large coalescent...

This data release is composed of three crustal (as opposed to subduction zone) geologic input datasets for the 2023 Alaska update to the U.S. National Seismic Hazard Model (NSHM): 1) fault section vector line data, 2) fault zone vector polygon data, and 3) accompanying earthquake geology attributes.

This dataset provides a detailed (1:10,000) digital map of fault and fold traces in Alaska, USA based on features identified in the freely available ArcticDEM 3.0. The fault traces represented in this dataset either revise the location and accuracy of known active faults or folds archived in the USGS Quaternary Fault and Fold Database, or represent the surface traces of active structures...

This data release includes 1 child item with tracking data for Greater White-fronted Geese, a species that nests in coastal areas of western and northern Alaska and winters across a broad area of North America along the Pacific and Central flyways. Child Item 1: "VHF Tracking Data for Pacific Flyway Greater White-Fronted Geese (Anser albifrons), 1987-1991" -- VHF tracking data for...
