This R script will run one replicate of one scenario used by Weiser (2021) to quantify biases in estimates of nest survival when nests are not found at the beginning of the nesting interval (age 0). The script simulates nest monitoring histories based on input parameters, applies models with or without an age effect to estimate daily survival rates, and calculates nest survival (to the...

The data release includes GIS data that map potential for tungsten skarn mineralization in permissive tracts in the Yukon-Tanana Uplands, Eastern Alaska, along with tables listing keywords and procedures used to produce the permissive tracts and score them for mineral potential.The GIS data are encapsulated in a file geodatabase called "AK_Wskarn_tract.gdb" and are also available in the...

These data are in six tables relating to surveys of eelgrass beds in three bays adjacent to Togiak National Wildlife Refuge, in southwestern Alaska. The tables provide environmental conditions, eelgrass abundance, distribution, and measurements used to estimate overall biomass.

These data are in six tables relating to surveys of eelgrass beds in Chignik Lagoon and Mud Bay, Alaska Peninsula-Becharof National Wildlife Refuges. The tables provide environmental conditions, eelgrass abundance, distribution, and measurements used to estimate overall biomass.

Field survey data of eelgrass distribution and abundance at Chignik Lagoon are available in a USGS Data Release: https://doi.org/10.5066/P9URZJYW Map data of eelgrass distribution from locations in Alaska (including Chignik Lagoon) are available in a USGS Data Release: https://doi.org/10.5066/P9WEK4JI

This data release contains the analytical results and evaluated source data files of geospatial analyses for identifying areas in Alaska that may be prospective for different types of lode gold deposits, including orogenic, reduced-intrusion-related, epithermal, and gold-bearing porphyry. The spatial analysis is based on queries of statewide source datasets of aeromagnetic surveys...

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...
