Data

This dataset provides walrus haulout group outlines, systematic grids cast over the outlines, and digitized points at the centroids of the individual walruses identified inside a randomly selected subset of grid cells. These data are based on visual interpretation of unpublished imagery from 26 aerial surveys by an Unoccupied Aerial System (UAS) operated by the U.S. Geological Survey, Alaska Scien

These data are in one table of variables that potentially influenced the immediate post-release survival of spectacled eiders (Somateria fischeri) from the Colville River Delta, Alaska marked with coelomically implanted satellite transmitters with percutaneous antennae in 2010 and 2011.

This is a single table containing measures of the amount of fat and meat consumed by 4 adult female and 5 adult male polar bears in U.S. zoos when provided both food sources ad libitum for 12-14 days. Trial length was intended to be 14 days, but trial dietary items ran out for two bears prior to the end of the trial (i.e., at 12 and 13 days instead of 14 days). The data set includes the weight of

These data represent estimates of den entrance and exit dates for female polar bears in the southern Beaufort and Chukchi Seas based on temperature sensor data obtained from satellite collars. An algorithm described in Olson et al. (2017) was used to determine whether the female entered a den and further analyses using temperature data as described in Olson et al. (2017) were used to assess den en

This data release contains one table which includes the concentration of cortisol from polar bear (Ursus maritimus) hair and morphometric data from some of the captured bears. We assayed concentration of cortisol in hair (HCC) from polar bears captured in the Alaska Beaufort, Bering and Chukchi seas during 1983-1989 and 2004-2016. Fields include the individual polar bear identifier (bearID), the d

Data for 819 pan concentrated stream-sediment samples, nonmagnetic heavy-mineral concentrate (HMC) samples, and chemical data for 93 of HMC samples is presented in data file geology_mineralogy_geochemistry_TaylorMtns_Alaska_Wang.csv. The samples were collected in 2004-2008 as part of a reconnaissance geochemical geological survey of drainage basins mostly in the Taylor Mountains 1:250,000-scale qu

This data set provides capture information and body size measurements of adult and gosling Greater White-fronted Geese captured at three study sites on the Arctic Coastal Plain of Alaska, 2012-2014.

This data set includes 15-minute interval data on stream temperature, stage, and discharge from an upstream and downstream gaging location on West Twin Creek, a first-order tributary to Nome Creek in the White Mountains of Alaska.

These data include stream water chemistry from headwater streams to large rivers across three national parks in Arctic Alaska: Bering Land Bridge National Preserve, Kobuk Valley National Park, and Noatak National Preserve.

This R script will run one replicate of one scenario used by Weiser (in review) 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 end of

This data release supports the paper titled, "Tungsten skarn potential of the Yukon-Tanana Uplands, Eastern Alaska, USA-A mineral resource assessment", published via open-access license in the Journal of Geochemical Exploration and available at: https://doi.org/10.1016/j.gexplo.2020.106700. The data release includes GIS data that map potential for tungsten skarn mineralization in permissive tracts

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