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.

Predictions of PFAS in groundwater used as a source of drinking water and related data in the conterminous United States Predictions of PFAS in groundwater used as a source of drinking water and related data in the conterminous United States
An extreme gradient boosting ensemble tree model predicting per- and polyfluoroalkyl substances (PFAS) occurrence in groundwater at the depths typical of the bottom of public and domestic drinking water supplies across the conterminous United States was developed. PFAS data used to train the model were collected between 2019 and 2022 by the U.S. Geological Survey National Water Quality...
Produced water major ion geochemistry, water isotopes, radium content, and field parameters and gas compositions from Niobrara Formation petroleum wells in the Denver-Julesburg Basin Produced water major ion geochemistry, water isotopes, radium content, and field parameters and gas compositions from Niobrara Formation petroleum wells in the Denver-Julesburg Basin
This data release includes field parameters (pH and specific conductance), major ion geochemistry (B, Ba, Br, Cl, Ca, Fe, K, Li, Mg, Mn, Na, Si, SO4, Sr), total dissolved solids, specific gravity, water isotopes (delta-2H and delta-18O), and radium isotopes (226Ra and 228Ra) from produced water samples taken from petroleum wells producing from the Niobrara Formation in the Denver...
Piacenzian (Pliocene) foraminiferal faunal census data from Sites DSDP 594, ODP 642, ODP 846, ODP 882, ODP 982, ODP 1073, ODP 1088, and ODP 1146 Piacenzian (Pliocene) foraminiferal faunal census data from Sites DSDP 594, ODP 642, ODP 846, ODP 882, ODP 982, ODP 1073, ODP 1088, and ODP 1146
Planktic foraminiferal species distributions in the modern ocean track environmental features like latitudinal temperature gradients. Species shift their distributions as the marine environment changes, providing an analog for past behavior. Stationarity of species’ ecological tolerances is a first-order assumption of all paleoenvironmental reconstructions based upon modern analog...
Remotely sensed data, field measurements, and MATLAB code used to produce image-derived velocity maps for a reach of the Sacramento River near Glenn, CA, September 16-19, 2024 Remotely sensed data, field measurements, and MATLAB code used to produce image-derived velocity maps for a reach of the Sacramento River near Glenn, CA, September 16-19, 2024
This data release provides remotely sensed data, field measurements, and MATLAB code associated with an effort to produce image-derived velocity maps for a reach of the Sacramento River in California's Central Valley. Data collection occurred from September 16-19, 2024, and involved cooperators from the Intelligent Robotics Group from the National Aeronautics and Space Administration...
Drought-related responses of stream flow, climate, and vegetation productivity from the Donner und Blitzen watershed, Great Basin Desert, USA (1988-2020) Drought-related responses of stream flow, climate, and vegetation productivity from the Donner und Blitzen watershed, Great Basin Desert, USA (1988-2020)
Indicators of climatic, hydrologic, and ecological drought responses in water-related terrestrial and aquatic conditions within a single catchment in the northwestern Great Basin Desert and its associated stream network were developed from stream flow, climate and remote sensing sources for the time period of 1988 to 2020.
