Data

This dataset consists of three tables with data associated with Red-tailed Hawks exhibiting beak deformities characteristic of avian keratin disorder (AKD). The first is comprised of Red-tailed Hawks collected or captured in the Northwest region of the United States. The second is a compilation of reports from citizen science observers or scientific literature. The third is a poecivirus...

This data release contains five spreadsheets of information from aerial surveys of the Indigirka River Delta, Russia, in June of 1993 and 1994, data on habitats where nests of Spectacled Eiders (Somateria fischeri) and other species of waterfowl were observed from 1993 to 1995, and genotypic data from feathers collected from eider nests to determine inter-annual rates of return by...

This dataset contains U-Pb isotopic data and associated dates of zircon from sedimentary and metamorphic rocks collected from the western Upper Peninsula of Michigan and northern Wisconsin, United States. The samples were collected as part of geological mapping and research conducted from 2019 to 2023 and funded by the Mineral Resources Program of the U.S. Geological Survey. Zircon...

This data set describes the assessment of surface waters in Denali National Park and Preserve and Wrangell St. Elias National Park and Preserve for antimicrobial resistance genes during four summer months (May - August).

Geologic map geodatabase depicting the geology of the Greater Antilles and Virgin Islands region, including countries of Cuba, Haiti, Dominican Republic, and Jamaica, and territories of Puerto Rico, the U.S. Virgin Islands, the British Virgin Islands, and the Cayman Islands. Database tables include: geologic linework, dikes, folds, geologic units, and geochronologic data.

These data represent movement metrics of adult female grizzly bears and polar bears with and without cubs-of-the-year at seven temporal scales after den departure. Grizzly bear data were collected in the Greater Yellowstone Ecosystem during 2000–2021 and in the Northern Continental Divide Ecosystem during 2003–2022. Polar bear data were collected in the Southern Beaufort Sea during 1986...

This dataset is one table with data collected and derived from polar bears sampled in Alaska from the Southern Beaufort Sea subpopulation during 2000-2023. Collected data includes individual identity, location of observation, observation type, estimated birth year, and demographic information. Data were collected from polar bears that were captured, remotely sampled using biopsy darts...

This data set describes the genomic bacterial analysis of swabs and tissues collected from whooping cranes in Louisiana. The data includes targeted analysis from quantitative PCR for bacterial pathogens.

This data release contains elemental concentration data from geochemical analysis of eight bulk placer tailing sediment samples and of size and density fractions derived from those eight samples. All placer tailing material collected for this data release originated from samples that were collected in Alaska. The samples collected from one fifth yard of tailings material, sieved to -1/4...

This dataset contains U-Pb isotopic data and ages plus trace element concentrations from titanite and apatite in igneous rocks collected for USGS projects in the Alaska Range, Yukon Tanana uplands of eastern Alaska, and a study of ophiolites in Alaska. A subset of analyses also includes simultaneous measurements of Sm-Nd isotope ratios. For this subset, split-stream configuration...

This data package contains six tables: 1) slash pile characteristics, 2) soil moisture and temperature below and nearby slash piles, 3) measurements of individual logs within slash piles, 4) characteristics of log cover objects nearby slash piles, 5) locations and body measurements of Sacramento Mountain salamanders (Aneides hardii) found under or within slash piles or individual log...

This data set describes results for two laboratory experiments to validate a quantitative PCR assay for the assessment of antimicrobial resistance genes in surface waters. Data are also provided for the application of the assay surface water samples collected from three national parks in Alaska.
