Data

This dataset describes the number and detection of Giardia cysts and Cryptosporidium oocysts in water samples collected from creeks and lakes in Anchorage, Alaska during 2021.

This data release contains information derived from fishing efforts and sampled fish from the nearshore Beaufort Sea, Alaska, 2021-2023, as part of a study investigating red-throated loon productivity and diet. The datasets include six tables comprising 1) catch per unit effort (CPUE) data, 2) field-measured lengths of fish (mm), 3) the energy density (kJ/g) and whole-body energy (kJ) of...

This dataset is one table with demographic, morphometric, and blood analyte measurements from whole blood and serum samples taken from a subset of polar bears sampled in Alaska's southern Beaufort Sea during 1989-2012. The measured blood analytes include: blood urea nitrogen, creatinine, glucose, total protein, hemoglobin, red blood cell count, packed cell volume, and hemoglobin A1c...

This dataset consists of the complete set of processed aerial imagery and survey data from walrus haulouts collected by unoccupied aerial system (UAS) surveys near Pt. Lay, Alaska, during the autumn 2024 and 2025. The data include georeferenced optical three band (red, green, blue) aerial images and orthoimages derived from those aerial images through the standardized structure from...

This project aimed to develop methods to estimate spatially explicit survival of wildlife from telemetry data.

These diet data were collected from the Porcupine caribou herd in northern Alaska and Yukon in summer 2021 during 4 periods: calving (occasion 1), post-calving (occasion 2), mosquito harassment (occasion 3), and mid-summer (occasion 4). Diet data was determined by two distinct techniques: DNA metabarcoding data from fecal pellets and video data from camera collars deployed on adult...

This data package contains 3 tables presenting site selection information, basin characteristics, subsidy to streamflow from glacier mass loss data, and other streamflow statistics for selected streamgages in Alaska that were used to evaluate the influence of glacier mass loss on streamflow in Alaska and conterminous basins in Canada. The first ("site_selection_outcomes.csv") contains...

Polar bears (Ursus maritimus) are difficult to study because of logistical challenges. Satellite radio collars are an excellent tool for efficiently collecting information on the distribution and habitat use of polar bears because they can be deployed for multiple years. Radio collars can be constructed using materials and devices that result in the collar falling off an animal so that...

Chemostratigraphic signatures were recorded in a 113 m thick outcrop of late Albian to early Campanian (~103–82 Ma) Hue Shale exposed on the bank of the Jago River in the coastal plain (“1002 Area”) of the Arctic National Wildlife Refuge (ANWR), Alaska. Spectral gamma-ray (SGR) data was collected in situ across the Jago River section. A total of 250 samples consisting of predominantly...

This data set describes serological data collected from mammals in Alaska and seropositivity to influenza A, clade 2.3.4.4b H5 highly pathogenic avian influenza (HPAI), North American lineage H5 low pathogenic avian influenza (LPAI), and N1 antigens.

This data release includes continuous measurements of stream temperature and specific conductance from 24 sites on the Yukon River and other arctic rivers in Alaska. Measurements were collected at selected U.S. Geological Survey stream gages and in communities along major rivers.

This dataset contains U-Pb isotopic data and associated ages of zircons from selected igneous rocks collected from the region surrounding and including the uplands of the United States Territory of Puerto Rico. The samples were collected as part of geological mapping and research conducted during 2018 and funded by the Mineral Resources Program of the U.S. Geological Survey. Zircon...
