Data

This data package presents legacy data on Emperor Goose, Cackling Goose, Black Brant, and Greater White-fronted Goose, breeding biology, behavior, and morphology collected at study sites near Kokechik Bay on the Yukon Delta National Wildlife Refuge (previously Clarence Rhodes National Wildlife Refuge), Alaska during the summers of 1982 through 1988. These data were collected to provide a basis for

This dataset identifies lead (Pb) concentration found in the blood of waterfowl sampled in western and northern Alaska and eastern Russia between 1993 and 2022. Data include age, sex, body measurement, capture location, presence or absence of lead shot on x-rays, and blood lead levels. Because the study took place over a number of years at the same study sites, many of the same birds were sampled

This dataset consists of drainage basin boundaries for selected transboundary basins draining to the Gulf of Alaska in south-east Alaska. Basins were delineated to the basin outlet using a tidal datum of mean high water (MHW). The drainage basins are provided as polygons attributed with basin drainage area and as polylines attributed with the data source for each line segment, respectively.

This data set includes information on collections of surface water and fecal samples from wild gulls (Larus spp.) at two locations on the Kenai Peninsula, Alaska, USA. Samples were screened for Escherichia coli (E. coli) and Klebsiella pneumoniae (K. pneumoniae) and tested for resistance to multiple antibiotics.

This data release supports the paper titled, "Insights into the metamorphic history and origin of flake graphite mineralization at the Graphite Creek graphite deposit, Seward Peninsula, Alaska, USA", published in the journal Mineralium Deposita. The data release includes zircon and titanite U-Pb-Thisotope and age data, monazite U-Pb-Th isotope, trace element and age data, carbon and sulfur stablei

WildCast (WILDlife Potential Habitat ForeCASTing Project) is a completed project led by USGS, in collaboration with the National Park Service, the U.S. Fish and Wildlife Service, and the U.S. Forest Service. This aerial photographic transect project of northwest Alaska, acquired photographs, videos, and associated data, during July 16, 17, and 18, 2013. The images depict land cover types as a base

This dataset includes locations and water surface elevation measurements from submersible pressure transducers deployed in channels of three rivers in Alaska: Susitna and Yukon Rivers (July-October 2020), and Nushagak River (May to September 2021).

These data are part of the Gulf Watch Alaska (GWA) long-term monitoring program and contain diet data from Black-legged Kittiwakes (BLKI), Rhinoceros Auklets (RHAU), and Tufted puffins (TUPU) located on Middleton Island in Prince William Sound, Gulf of Alaska. The first table consists of information on seabird diet samples including the sampling method and number of prey types identified per sampl

These data are in four tables relating to nest visit data of Emperor Geese on the Yukon-Kuskokwim Delta in Alaska, 1994-2017. The tables provide: (1) nest visit and hatch success, (2) visit history, (3) capture history, and (4) environmental covariates such as fox and vole abundance and weather data. The code used to conduct the analyses is also included as a text file.

This data release provides the source data and results of a flood frequency analysis and annual exceedance probability estimation for a flood that occurred on July 11, 2022 in the Delta River Basin, Alaska. Data are provided for two streamgages that had at least 10 years of peak-flow record. The data include streamgage information, PeakFQ input (.txt and .PSF files) PeakFQ output (.PRT, .EXP, and

This data package contains three tables: 1) avian point-transect survey data collected on the Seward Peninsula in 2012, 2) locations of all survey sites, and 3) an avian taxonomy table for reference.

This data package contains two tables with habitat measurements from each sampling point used in avian point-transect surveys on the Seward Peninsula in 2012 and the locations of those sites. Measurements include percent cover and canopy height of alder (Alnus spp.), dwarf birch (Betula spp.), ericaceous shrubs (e.g., Empetrum, Vaccinium spp.), herbaceous, lichen (e.g., Cladonia spp.), and willow
