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.

Data release for Remotely Sensed Surface Water Storage Shows Distinct Patterns from SWAT-Simulated Data Data release for Remotely Sensed Surface Water Storage Shows Distinct Patterns from SWAT-Simulated Data
Understanding and projecting the downstream benefits of terrestrial surface water storage (volumetric water stored in lakes and wetlands, SWstorage) requires watershed hydrologic models. Use of external datasets to calibrate and validate modeled SWstorage dynamics remains uncommon, particularly across major river basins. Here, we: (1) developed and assessed the utility of a novel remote...
Machine Learning Model: Estimates of Metal Abundance in Global Seafloor Massive Sulfide Deposits Machine Learning Model: Estimates of Metal Abundance in Global Seafloor Massive Sulfide Deposits
A multi-stage ensembled machine learning model was developed to estimate metal abundances in seafloor massive sulfide deposits worldwide. The modeling framework integrates (1) KMeans++ clustering to identify geochemical groupings based on enrichment controls, (2) Random Forest classification to assign geochemical labels to vent fields with incomplete or absent geochemical data, and (3)...
Organic content and carbon dating of soil samples collected from a fen in Big Smoky Valley, Nye County, Nevada Organic content and carbon dating of soil samples collected from a fen in Big Smoky Valley, Nye County, Nevada
This U.S. Geological Survey data release consists of two comma-separated values (CSV) tables containing the results of organic content and radiocarbon dating analyses performed on soil samples collected from a fen in Big Smoky Valley, Nye County, Nevada. Samples were collected from a single soil boring referred to as F1-D on September 11, 2019, using a hand auger. A shapefile of the site...
USGS National and Global Oil and Gas Assessment Project—Permian Basin Province, Texas and New Mexico—Assessment Unit Boundaries, Assessment Input Data, and Fact Sheet Data Tables USGS National and Global Oil and Gas Assessment Project—Permian Basin Province, Texas and New Mexico—Assessment Unit Boundaries, Assessment Input Data, and Fact Sheet Data Tables
This data release contains the boundaries of assessment units and input data for the assessment of undiscovered oil and gas resources in the Woodford and Barnett Shales of the Permian Basin Province, Texas and New Mexico. The assessment unit is the fundamental unit used in the National Assessment Project for the assessment of undiscovered oil and gas resources. The assessment unit is...
Low-flow metrics and explanatory variable data for 107 basins in Massachusetts, 1943-2022 Low-flow metrics and explanatory variable data for 107 basins in Massachusetts, 1943-2022
The U.S. Geological Survey, in cooperation with the Massachusetts Department of Conservation and Recreation, evaluated potential drivers of low streamflows in Massachusetts by use of statistical models with selected low-flow metrics as the dependent variables. Low-flow metrics were computed in six ways: the 2nd and 10th percentile of daily flows during a climate year, these same...
Reconnaissance of imidacloprid in select Virginia streams, 2024–2025 Reconnaissance of imidacloprid in select Virginia streams, 2024–2025
This data release presents concentration results obtained using an enzyme-linked immunosorbent assay (ELISA) method for imidacloprid and other neonicotinoid insecticides from samples collected in 30 urban streams across Virginia between August 2024 and July 2025. ELISA analyses were conducted at the U.S. Geological Survey Strategic Laboratory Science Branch in Boulder, Colorado. The...
Synthesized Domestic Well Database for the Conterminous United States Synthesized Domestic Well Database for the Conterminous United States
Self-supplied domestic water sources play a significant role in the United States' water landscape, serving approximately 13 percent of the nation's population as of 2015 (Dieter and others, 2018). However, these sources present unique challenges for water resource management and research due to the lack of monitoring, withdrawal location, and place-of-use data. To address this data gap...
Greenhouse Gas Fluxes along a Tidal Gradient of Low Salinity Freshwater Forested Wetlands Greenhouse Gas Fluxes along a Tidal Gradient of Low Salinity Freshwater Forested Wetlands
A dynamic closed chamber system was used to measure in situ efflux rates of CO2, CH4, and N2O to the atmosphere from wetland soils along the Mattaponi and Pamunkey rivers. These greenhouse gas (GHG) flux measurements were taken quarterly from December 2015 to September 2017, at replicated hummock and hollow microtopography locations (where present) within each site. CO2 flux was measured...
Mississippi Barrier Islands Habitat Classification, National Wetlands Inventory, December 2017: (Cat Island, Ship Island, Horn Island, and Petit Bois Island) Mississippi Barrier Islands Habitat Classification, National Wetlands Inventory, December 2017: (Cat Island, Ship Island, Horn Island, and Petit Bois Island)
This data set consists of digital data describing wetlands and uplands habitats for the Mississippi Coastal Improvements Program (MsCIP) area, consisting of Cat, Ship, Horn and Petit Bois Islands for the year 2021. Wetlands were classified using the Cowardin et al. (1979) wetlands classification scheme to the level of freshwater and tidal salinity modifiers. For this dataset, upland...

This dataset contains data from a trapping effort targeting Razor-backed Musk Turtles (Sternotherus carinatus) across Louisiana.
Per- and Polyfluoroalkyl Substances (PFAS) and Co-occurring Contaminants in the Fraser River, a Headwater Tributary to the Colorado River - September 2021 to August 2023 Per- and Polyfluoroalkyl Substances (PFAS) and Co-occurring Contaminants in the Fraser River, a Headwater Tributary to the Colorado River - September 2021 to August 2023
The Fraser River, located in the Colorado Rocky Mountains, is a headwater tributary to the Upper Colorado River. This investigation by the U.S. Geological Survey (USGS) Water Mission Area, Water Quality Processes Program Proxies Project was conducted from September 2021 through August 2023 and consisted of eight sampling events incorporating 17 sites (15 stream sites and two wastewater...
