Data

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.

This data package includes genotype data for two independent sets of American black bear (Ursus americanus) samples. The first set of samples was collected from 85 adult bears harvested by permitted hunters in southcentral Alaska from 1994-2019; we hereafter refer to these as "hunter-harvested" samples. These hunter-harvested samples were genotyped with restriction site-associated...

GPS collar location data were collected as part of a long-term study on caribou (Rangifer tarandus granti) in the Denali herd of Alaska. Collars were deployed on adult (greater than or equal to 2 years) female caribou from 2010-2013, and then refurbished and redeployed on adult (greater than or equal to 4 years) male caribou from 2014-2018. The collars were manufactured by Telonics (TGW...

This data set provides polar bear (Ursus maritimus) microsatellite genotypes derived from 21 loci (CPH9, CXX20, CXX110, CXX173, G1A, G10B, G10C, G1D, G10H, G10J, G10L, G10M, G10P, G10U, G10X, Mu26, Mu50, Mu51, Mu59, MSUT-2, REN145P07). Blood serum and hair samples for microsatellite genetic analysis were collected from polar bears from the Chukchi Sea between 1986 and 2019. Serum samples...

This dataset consists of a complete set of audio recordings collected near a large walrus haulout at Point Lay, Alaska, during September of 2024. The recordings were collected using the Song Meter Mini 2 (Wildlife Acoustics, Inc., Maynard, MA) at two sites, one within 150 m of a large walrus herd resting on shore and one placed more than 4 km to the south of the herd directly under the...
