Data

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...

This data set contains various reported age determinations from various rock types collected from the larger region surrounding and including the islands of the Greater Antilles and United States Territory of Puerto Rico. Although a select few of the samples were collected as part of geological mapping and research conducted and funded by the Mineral Resources Program of the U.S...

Acoustic recorders can detect the presence of birds and these detections may be used for the purpose of population abundance or estimation. This monitoring project compared the abundance of tundra-breeding birds detected through both acoustic monitoring and observational surveys. The data package is comprised of four tables: (1) habitat type, including vegetation height at sites where...

This dataset contains morphological measures of 21 Pacific walruses in human care in the United States, Belgium, and Germany measured directly and via an aerially mounted camera in 2022 and 2023. Six individuals were measured twice: once at their typical annual lowest body mass and once at their typical annual maximum body mass. The remaining 15 individuals were measured on one occasion...

This dataset summarizes selected basin and streamflow special conditions for USGS streamgages in Alaska that are commonly used for site and period of record selection for regional analyses, through water year 2022. The data consist of a table providing information about the type of streamflow available for the site, site special conditions related to the timing of data collection, basin...

This dataset provides estimated Remote Sensing Streamflow (RSQ) data at selected river reaches in Alaska. Reach-specific relations between satellite-derived water-surface elevation data and dynamic surface water extent data were used with a modified form of the Manning's streamflow equation to estimate streamflows. The streamflow estimates were used to create rating tables that define...

This data release contains measurements from continuous monitors of stream temperature, groundwater temperature, and well water levels, and discrete measurements of discharge and stream shading.

This data release corresponds to visual vegetation measurements in snow goose grazing areas of the Colville River Delta. Visual vegetation measurements data include functional group percent cover and evidence of goose activity including grazed stems, snow goose grubbing holes, and shoot pulling. These data were collected at a set of four 100m transects located in areas of representative...

These data are in two tables: 1) table relating to emperor goose nest visit, nest fate, and nest dispersal distances on the Yukon-Kuskokwim Delta in Alaska, 2000-2017; 2) table with means and standard deviations for posterior distributions of predicted nest-age and year specific daily nest survival probabilities for emperor geese derived from estimates reported by Thompson et al. (2023)...
