Data

This dataset contains U-Pb isotopic data and associated ages of titanite from one sample and detrital zircon grains from 33 sedimentary and metasedimentary rocks collected from the western Alaska Range in south-central Alaska. The samples were collected as part of geological mapping and research conducted between 2010 and 2014 and funded by the Mineral Resources Program of the U.S...

This data release provides descriptions of more than 120 mineral regions, mines, and mineral deposits within the United States that are reported to contain enrichments of tin (Sn). This data release only includes sites with publicly available records of past production of tin, or a defined resource of tin, or both. The inclusion of a particular mineral deposit in this database is not...

Sea ice loss represents a stressor to the Pacific walrus (Odobenus rosmarus divergens), which feeds on benthic macroinvertebrates in the Bering and Chukchi seas. However, no studies have examined the effects of sea ice on foraging walrus space use patterns. Thus, we examined walrus foraging resource selection as a function of proximity to resting substrates and prey biomass with a...

This data set contains information (in two tables) on nesting habitat and nest survival for American (Pluvialis dominica) and Pacific (P. fulva) Golden-Plovers monitored at seven study sites across an elevational gradient (28-416 m) on the Seward Peninsula in northwestern Alaska during the summers of 2012 and 2013. We used principal components analysis to reduce habitat measurements into...

The data package "Sea Otter Aerial Survey Data from Southeast Alaska, 2002-2003" provides raw data for examining abundance and distribution of northern sea otters (Enhydra lutris kenyoni) in Southeast Alaska, based on data collected during a series of population-wide aerial surveys. The USGS aerial sea otter surveys have been completed multiple times using consistent methodology...

Data sets containing: (1) sample collection and influenza A virus (IAV) screening information for wild ducks, (2) water temperature data for six North American wetlands, (3) water quality measurement from those wetlands, (4) laboratory-based study of viral viability using Minnesota wetland water, (5) naive mallards challenged experimentally with IAVs identified from the field experiment...

This data set is comprised of one table with Steller's Eider sample information and allele sizes for 6 microsatellite loci (Sfiµ3, Sfiµ4, Sfiµ10, Sfiµ11, Bcaµ11, Smo10).

This dataset is four tables containing cosmogenic beryllium-10 and aluminum-26 concentrations and related data, as well as infrared stimulated luminescence data, from samples collected at 21 sites along the Fortymile River in eastern Alaska and Yukon, Canada between 2016 to 2018, and processed between 2016 and 2019. The file "burialDating_siteLocations_fortymile_bender.csv" contains site...

This data set contains bill and tarsal measurements from 114 Bristle-thighed Curlews, captured on breeding grounds in Alaska, and non-breeding areas in Hawaii and Reitoru atoll, French Polynesia.

These data are part of the Gulf Watch Alaska (GWA) long term monitoring program, nearshore monitoring component. Specifically, these data describe sea otter (Enhydra lutris) aerial survey observations from the waters around Katmai National Park and Preserve from surveys conducted in 2008, 2012, 2015, and 2018. Sea otters are a keystone predator, well known for structuring the nearshore...

These data are part of the Gulf Watch Alaska (GWA) long term monitoring program, nearshore monitoring component. The dataset is a comma separated file exported from a Microsoft Excel spreadsheet. The data consist of information related to collection of sea otter carcasses. Collectors walked selected shorelines searching for signs of carcasses. Date, location, carcass condition, parts...

This R script will run one example of the stochastic matrix models run by Weiser et al. (2020) to simulate shorebird populations. The model predicts population growth rates and elasticity values of vital rates. The example script is stand-alone and contains input values for one example species; input values for the other species are provided in the manuscript.
