Breeding Biology, Behavior, and Morphology of Emperor Geese and Other Waterfowl near Kokechik Bay, Yukon Delta National Wildlife Refuge, Alaska during 1982-1988

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 the evaluation of long-term changes in Emperor Goose and other waterfowl biology on the Yukon-Kuskokwim Delta, Alaska.

Waterfowl Lead Exposure Data in Alaska and Russia

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 in multiple years.

Corrected Fire Perimeters of Alaska's National Wildlife Refuges

This data package includes 481 geospatial vector polygons of historic fire perimeters associated with National Wildlife Refuges in Alaska. These polygons, originally held within the Alaska Large Fire Database (ALFD), were reviewed and found to have geospatial inaccuracies with respect to the fire they represent. They were corrected and updated based on a variety of remote sensing resources; the Monitoring Trends in Burn Severity (MTBS) database (https://www.mtbs.gov/viewer/index.html), geospatial rasters of historic fire activity derived from Landsat 1-9 imagery in the Google Earth Engine(https://earthengine.google.com) environment, and historical air photos acquired through EarthExplorer (https://earthexplorer.usgs.gov/)....
