Data Releases

This data release provides digital flight line data for a high-resolution airborne magnetic and radiometric survey over the Elk Creek region of Nebraska and Kansas. The airborne survey was funded by the Earth Mapping Resources Initiative (Earth MRI). The survey was designed by the USGS in collaboration with the Nebraska Conservation and Survey Division and the Kansas Geological Survey...

This data release contains coastal wetland synthesis products for the Delaware Bay-facing New Jersey salt marshes. Metrics for resiliency, including the unvegetated to vegetated ratio (UVVR), marsh elevation, tidal range, and lifespan are calculated for smaller units delineated from a digital elevation model, providing the spatial variability of physical factors that influence wetland...

In May and June 2023, the U.S. Geological Survey, in collaboration with the Massachusetts Office of Coastal Zone Management, collected high-resolution geophysical and seafloor sampling data, in Nantucket Sound to understand the regional geology in the vicinity of Horseshoe Shoal. Geophysical data collected include swath bathymetry, backscatter, and seismic reflection profile data. Ground...

This U.S. Geological Survey (USGS) data release provides a digital geospatial database for the geologic map of the mineral resource potential of the Savage Run Wilderness, Carbon and Albany Counties, Wyoming (McCallum and Kluender, 1983). Attribute tables and geospatial features (points, lines and polygons) conform to the Geologic Map Schema (USGS NCGMP, 2020) and represent the geologic...

This data release contains the boundaries of assessment units, assessment input data, and resulting fact sheet data tables for the assessment of undiscovered conventional oil and gas resources in the Berkine, Illizi, Hamra, Murzuq, and Erdis Kufra Basins of northern Africa. The assessment unit is the fundamental unit used in the National and Global Oil and Gas Assessment (NAGA) Project...

This data set includes survival data for arctic grayling exposed to various concentrations of 6PPD-quinone (6PPDQ) for up to 96 hours. Concurrently collected analytical water chemistry and general water quality measurements are included. In addition, tissue concentrations of 6PPDQ for fish that died during exposure and those that survived to the end of the exposure are included.

Stable isotope dataset from fauna, particulate organic matter (POM) and sediments used to construct isotopic niches to compare trophic relationships in mesophotic coral habitats across the Gulf of America.

This data release provides the input and output files, metadata, and R scripts used to apply a Structural Topic Model (STM) to public (local news articles) and scientific (abstracts) discourse on water quality in the Illinois River Basin (ILRB). A total of 6,822 local news articles published from 2018 through 2022, and 190 scientific abstracts published from 2018 through 2023 were...

The Central Valley Hydrologic Model version 2 (CVHM2) simulation period has been extended to the year 2100 to assess the feasibility of groundwater level sustainability goals established under California's Sustainable Groundwater Management Act (SGMA). The original CVHM2 model simulated monthly groundwater budgets from 1961 to 2019. This data release extends the simulation period to the...

Clear Lake is a 180 km2 freshwater lake located approximately 120 km northwest of Sacramento in the California Coast Range. The lake is a popular sport-fishing destination, however, there are fish consumption advisories associated with mercury (Hg) contamination for several species. The lake has three arms: a large open-water region to the northwest (Upper Arm), a smaller and narrower...

The U.S. Geological Survey (USGS), in cooperation with the Colorado Department of Transportation, developed peak-, mean-, and low-streamflow regional-regression equations for natural streamflow in central and western Colorado. A total of 418 streamgages were selected for the study having a minimum of 10 years of unregulated streamflows. This data release presents hydrologic data through...

We captured and collared desert kit foxes in three populations near solar facilities in the Sonoran and Mojave Deserts, California, between November 2022 and January 2023 and in January 2024. This dataset includes telemetry records collected from 21 collared foxes from November 2022 to January 2025. We used these data to estimate home-range sizes for each fox and to evaluate habitat use...
