Data

This data release provides digital geospatial data related to the three-dimensional geologic model (Hosford Scheirer, 2013) that was used as a framework for conducting the 2003 oil and gas assessment of the San Joaquin Basin province, California (Gautier and others, 2004; Hosford Scheirer, ed., 2007). The data release includes raster GeoTIFF files of the tops of the 15 composite geologic...

This data release provides vector flight-line (point) and raster data for a high-resolution airborne magnetic and radiometric survey over a part of the eastern Great Basin, Nevada. The survey was acquired as part of the UGSS Earth Mapping Resource Initiative (Earth MRI) to improve our understanding of the fundamental geologic framework of the region with applications to evaluating...

This release of whole-rock geochemical data for northwestern Utah and adjacent states is for volcanic rocks sampled and analyzed from 1977 to present. The rocks range from Eocene to Quaternary in age and represent lava flows, tuffs, and subvolcanic intrusions. The data release includes new, previously unpublished data as well as results for USGS-processed samples that are publicly...

Presence/absence data for Erodium pollen in a sediment core taken from the Morro Bay Salt Marsh.

This release of whole-rock geochemical data for northwestern Utah and adjacent Idaho and Nevada is for unaltered intrusive rocks sampled and analyzed from 1980 to 2023. The rocks range in age from Archean to Cenozoic. Most samples represent plutons, stocks, and dikes of Mesozoic and Cenozoic age. A few older igneous and metamorphic rocks are included. The data support several map...

Microplastics (MPs) are an environmental concern. They can interact with other contaminants and pose new threats to organisms. We assessed the effect MPs on silver (Ag) bioaccumulation in the filter-feeding zooplankton Daphnia magna exposed to Ag nanoparticles at environmentally relevant concentrations.

This data release provides annual values for the 19 standard bioclimatic variables (BIO1–BIO19) for the Contiguous United States, computed from the downscaled CMIP6-LOCA2 temperature and precipitation dataset for 1950–2100. Daily maximum temperature, minimum temperature, and precipitation from 27 CMIP6-LOCA2 GCMs were processed using the Python xclim library to generate bioclimatic...

Geochemical data include major, minor and trace element results for alkaline silicate igneous rock samples from the Bear Lodge alkaline complex. Samples were collected during field work from natural exposures/outcrops and drill core. Samples were analyzed by the GeoAnalytical Lab at Washington State University and U.S. Geological Survey contract laboratories, AGAT Labs and SGS Labs...

This U.S. Geological Survey (USGS) data release is a collaborative geospatial database compiled by the USGS and participating State geological surveys, with support from the Earth Mapping Resources Initiative (Earth MRI) program. The database represents the first phase of cataloging above-ground mine waste features —such as tailings and waste rock piles— that are remnants of historical...

The area of study is restricted to the northern Appalachian region between latitudes 38N and 48N and longitudes 66W and 77W in the U.S. states of Maine, New Hampshire, Vermont, New York, Massachusetts, Connecticut, Rhode Island, Pennsylvania, and Delaware. This study (Wintzer and others, 2025) integrates data from several sources, including geologic, geochemical, geophysical, watershed...

This project has inventoried and produced a digital database of Late Miocene through Holocene micropaleontologic slides and data available in the USGS collections along the lower Colorado River corridor, Imperial Valley, and Gulf of California. The digital database includes the location of samples, content of the samples, results of analyses, and other information in a format that can be...

NOAA’s Assessment Technical Support Unit (TSU) created a suite of temperature and precipitation metrics of extremes and threshold exceedance variables based on the Climate Model Intercomparison Program Phase 6 CMIP6 Localized Constructed Analogs (CMIP6-LOCA2) data set to support the Fifth National Climate Assessment (NCA5). Following the v20240915 revision of the CMIP6-LOCA2...
