Data Releases
The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.

Time Domain Electromagnetic (TEM) data and Horizontal-to-Vertical Spectral Ratio (HVSR) passive seismic data collected for the Next Generation Water Observing System (NGWOS) Illinois River Basin (IRB) Program, 2022 Time Domain Electromagnetic (TEM) data and Horizontal-to-Vertical Spectral Ratio (HVSR) passive seismic data collected for the Next Generation Water Observing System (NGWOS) Illinois River Basin (IRB) Program, 2022
In November 2022, Ground-based time domain electromagnetic (TEM) data and Horizontal-to-Vertical Spectral Ratio (HVSR) passive seismic soundings were acquired by the U.S. Geological Survey (USGS) at 27 locations throughout the Illinois River Basin (IRB). The USGS collected these data to characterize the subsurface resistivity structure and depth to bedrock in support of the USGS Next...
Microfossil samples from the San Andreas Fault Zone and surrounding areas in and near Pinnacles National Park, central California Microfossil samples from the San Andreas Fault Zone and surrounding areas in and near Pinnacles National Park, central California
This data release includes microfossil data, including flora and fauna lists, as well as microfossils zonation and numeric age range, for samples collected in and around the San Andreas Fault Zone in and near Pinnacles National Park between 2010-2012.
Ground Magnetic Observations of the Mammoth Magnetic Anomaly, Pinal County, Arizona, May 2025 Ground Magnetic Observations of the Mammoth Magnetic Anomaly, Pinal County, Arizona, May 2025
This data release provides ground magnetic data collected in May 2025 at the Mammoth Magnetic Anomaly (MMA) site in Pinal County, Arizona. These data were collected to validate and characterize a large aeromagnetic anomaly observed in an airborne survey of southeastern Arizona (Scheirer et al., 2025). The geophysical fieldwork was funded by the Earth Mapping Resources Initiative. Ground...
Argon Geochronology Data from Pleistocene Volcanic Deposits Along the Pit River, California Argon Geochronology Data from Pleistocene Volcanic Deposits Along the Pit River, California
Argon geochronology results date eruptions of mapped volcanic deposits north and south of the PIt River in the California Cascades. This data release includes both raw data and summary data. Summary data are the results USGS geochronologist(s) recommend be cited in geologic history publications.
Preliminary Geology of the North Meadow Creek Area, Tobacco Root Mountains, Southwest Montana: Measurements along the North Meadow Creek Fault Preliminary Geology of the North Meadow Creek Area, Tobacco Root Mountains, Southwest Montana: Measurements along the North Meadow Creek Fault
A previously unmapped fault forms a low scarp on a terrace along North Meadow Creek, a drainage on the east flank of the Tobacco Root Mountains, in SW Montana. The fault extends ~7.5 km between points where it disappears beneath alluvium of Madison Valley, on the SE, and glacial moraines on the NW. It appears on neither the Geologic Map of Montana nor the Quaternary Fault and Fold...
Argentine black and white tegu (Salvator merianae) morphometrics and gastrointestinal contents, Florida, 2016-2021 Argentine black and white tegu (Salvator merianae) morphometrics and gastrointestinal contents, Florida, 2016-2021
The dataset contains the gastrointestinal contents of 275 Argentine black and white tegus (Salvator merianae) collected between 2016 and 2021 from two geographically isolated populations in Florida: one in Miami-Dade County, established around 2011, and another in Charlotte County, established in 2018. Dietary analysis revealed a broad spectrum of consumed items, including vertebrates
Streamflow regressions, daily mean streamflow estimates, and annual and monthly streamflow statistics for Clearwater River tributaries in Central Idaho Streamflow regressions, daily mean streamflow estimates, and annual and monthly streamflow statistics for Clearwater River tributaries in Central Idaho
The U.S. Geological Survey (USGS), in cooperation with the Nez Perce Tribe, used streamflow measurements at 12 ungaged, partial-record sites and developed relationships with nearby USGS real-time streamgages (index sites) to provide daily mean streamflow values at partial-record sites in the Clearwater River basin. Daily mean streamflow was estimated by developing a regression...
Autonomous and manual environmental DNA detections of Round Goby (Neogobius melanostomus) in the Hudson River (New York) in June 2024 Autonomous and manual environmental DNA detections of Round Goby (Neogobius melanostomus) in the Hudson River (New York) in June 2024
Quantitative PCR results for samples collected from the Hudson River near Troy, New York by autonomous and manual (backpack) samplers
Environmental DNA sample results from Naval Base Ventura County Point Mugu Sea Range, May and June 2025 Environmental DNA sample results from Naval Base Ventura County Point Mugu Sea Range, May and June 2025
We used an environmental DNA (eDNA) autosampler and a backpack manual sampler to collect eDNA samples at Naval Base Ventura County's Point Mugu Sea Range in May and June 2025. Samples were sent to Wilderlab for metabarcoding analysis using their basic panel of five primers to amplify DNA from a variety of taxa, including vertebrates (fish, mammals, reptiles, amphibians, and birds)...
Domestic self-supplied household locations, counts, and withdrawal estimates in the conterminous United States: model and dataset for decadal year 2020 Domestic self-supplied household locations, counts, and withdrawal estimates in the conterminous United States: model and dataset for decadal year 2020
The U.S. Geological Survey is developing national water-use estimates as part of a project to support water resources management in the United States. Models support a nationally consistent approach to estimating water-use, are repeatable and reusable for their stated purpose which supports efficient updates to the results and have capabilities that allow users to generate forecasts of...
Results and Code From the North American Bat Monitoring Program's (NABat) Integrated Species Distribution and Trend Models for Hoary Bat and Silver-Haired Bat Results and Code From the North American Bat Monitoring Program's (NABat) Integrated Species Distribution and Trend Models for Hoary Bat and Silver-Haired Bat
These data contain results and model code from the North American Bat Monitoring Program's (NABat) integrated species distribution and trend models for the hoary bat (Lasiurus cinereus) and silver-haired bat (Lasionycteris noctivagans). These results document population status and trends based on the first continental-scale, comprehensive analysis of NABat data for tree bats (2012–2023)
Basin-fill thickness of the Arroyos and Northeast Air Force Research Laboratory areas, Edwards Air Force Base, California Basin-fill thickness of the Arroyos and Northeast Air Force Research Laboratory areas, Edwards Air Force Base, California
This data release contains a gridded shapefile of basin-fill thickness constructed from geologic maps, gravity-derived depth to bedrock, and a digital elevation model. The data were generated by the U.S. Geological Survey under cooperative agreement with the U.S. Air Force Civil Engineer Center to characterize the hydrogeology of the Arroyos and Northeast Air Force Research Laboratory...
