Data

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 two compo

Sea ice loss represents a stressor to the Pacific walrus, 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 matched use-availability design. We quantif

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 involving aerial-b

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, and (6) g

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 comprises 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 "geology_siteLocations_Fortymile_bender_2020.csv" contains site lo

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 marine ecos

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 collected, an

This data release includes 2 child items with tracking data for Black Scoters, a sea duck species that breeds throughout higher latitudes of Alaska and Canada and winters along coastal areas of North America. Child Item 1: "Argos Satellite Tracking Data for Black Scoters (Melanitta americana) - Processed Data" -- Quality-controlled data collected from Argos satellite transmitters. Ch

This metadata document describes the data contained in the "rawData" folder of this data package. This data package contains all data collected by the Argos System from 25 satellite transmitters attached to Surf Scoters on their winter ranges in southeast Alaska and Baja California, Mexico, 2005-2008. Five data files are included in the "rawData" folder of this data package. Two data files (with i

These data are three sets of aerial photos used to estimate the number of walruses at a haulout near Pt. Lay, Alaska in September 2014. They were collected during photographic aerial surveys of the only major haulout that occurred on the eastern shores of the Chukchi Sea after sea ice receded beyond the continental shelf on 25 and 27 September 2014.
