All Data

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 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...

Data describe designed environmental DNA (eDNA) experiments for the estimation of eDNA shedding and degradation rates for the Oyster Mussel (Epioblasma capsaeformis) at different biomass densities from water samples collected in the laboratory. A total of 12 experimental tanks (3 per biomass treatment) were used and randomly assigned one of the following biomass treatments: control = 0...

This data release contains supporting input data tables and results from analysis to identify and interpret clusters of drought events with similar meteorological and hydrological characteristics in the Delaware River Basin. Input data consists of hydrologic variables from the National Hydrologic Model Infrastructure with Precipitation-Runoff Modeling System, version 1.1 (NHM-PRMS v1.1)

The United States Geological Survey Virginia and West Virginia Water Science Center (USGS VA-WV-WSC) and City of Roanoke, Virginia assembled this data release to support a report that analyzed factors affecting benthic macroinvertebrate health in the City of Roanoke, Virgina between calendar years 2020 and 2023. The benthic macroinvertebrate and stream habitat sampling and surveying were...

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 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...
