Data Releases

This data release includes whole rock (WR) geochemical data, and uranium-lead isotopic data collected using a sensitive high resolution ion microprobe-reverse geometry (SHRIMP-RG) instrument; the SHRIMP-RG is a type of secondary ion mass spectrometer (SIMS). Whole rock geochemistry data were analyzed at Actlabs in Ancaster, Ontario, Canada. SHRIMP-RG data were collected at the USGS...

This work contributes to an understanding of the hydrologic cycle of the State of Alaska, USA, and parts of the Canadian Yukon Territory and British Columbia Province draining into Alaska. For purposes of this study, the domain is simply referred to as “Alaska (AK)". This data release contains inputs for and outputs from hydrologic simulations for the Alaska (AK) domain using the...

This work contributes to an understanding of the global hydrologic cycle. Global Circulation Model (GCM) data from National Aeronautics and Space Administration (NASA) were processed into 10 mean-monthly global datasets stored in NetCDF formatrepresenting 12 mean-monthly layers ( .nc file extension; https://www.unidata.ucar.edu/software/netcdf/ ). These NetCDF files are used as...

This release contains catch, diet composition, and invertebrate community data on six separate sampling events over a 24-Hour period associated with determining the food availability and food selectivity for Swallowtail Shiners, Notropis procne, in Upper Little York Lake, New York.

The North American Bat Monitoring Program (NABat) leverages acoustic monitoring as a scalable method for collecting detection-non-detection and activity data across multiple bat species through space and time. These valuable data, collected by hundreds of partners across North America, facilitate advanced statistical analyses of bat distributions, relative abundance, and ecological...

This data release contains mark-recapture and associated environmental data for blue sucker (Cycleptus elongatus) collected in the lower Colorado River, Texas, from 2016 through 2026. The release includes capture records from 16 field events, combined into 13 primary sampling occasions for analysis, across up to 40 electrofishing sites, with information on sampling dates, site...

This model archive summary describes the development of an acoustic derived suspended sediment time series computation model. The model archive summary describes the methods and techniques used to develop the model for the Columbia River at Vancouver, WA – USGS site ID 14144700. The time series suspended sediment data will help determine the suspended sediment concentration at the site...

Embryonic zebrafish (Danio rerio) were exposed to 0, 1.93, or 15.46 micrograms per liter of total polycyclic aromatic hydrocarbons (tPAHs) present from a low energy water accommodated fraction (LEWAF) of crude oil from the Brazilian oil spill in 2019. Embryos were exposed from 4 hours post fertilization (hpf) through hatching and sampled at 24, 48, 72,96, 120, 144, or 168 hpf. Zebrafish...

Gridded surfaces of bathymetry (50-meter resolution) and acoustic backscatter (25-meter resolution) were produced from 12 kHz Kongsberg Maritime EM124 multibeam echo sounding data of the Samoa Basin seafloor within the United States Exclusive Economic Zone surrounding the Territory of American Samoa. Together, these two datasets of seafloor elevation and seafloor character (substrate...

Coastal vegetated ecosystems play a vital role in reducing hurricane impacts on nearby communities. Different types of vegetation and landcover create varying levels of drag that help lessen hazards such as flooding and erosion. However, coastal landcover is constantly changing due to storms, tides, waves, and human activities. Existing satellite landcover products, such as the annual...

These physical and geochemical (elemental) data are from dust collected in the Kaibab National Forest and Grand Canyon National Park near the Pinyon Plain Mine. Samples were collected by the U.S. Geological Survey Utah Water Science Center (West Valley City, Utah) using low‑cost passive samplers. The samples were processed at the Utah Water Science Center, and elemental analyses were...

All the data presented here were compiled from published U.S. Geological Survey National oil and gas assessment results, both hardcopy and digital, from 1995-present. Each record in the table has been published previously as part of a conventional or continuous assessment under the National and Global Assessment (NAGA) Project. This data release includes more than 700 records from 70...
