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.

MODFLOW-6 model of variable-density groundwater flow and brine discharge to the Dolores River in the Paradox Valley, Colorado MODFLOW-6 model of variable-density groundwater flow and brine discharge to the Dolores River in the Paradox Valley, Colorado
MODFLOW-6 with the Groundwater Flow (GWF) and Groundwater Transport (GWT) models was used to simulate the geohydrology of the aquifer system of the Paradox Valley in western Colorado. Salinity of the Colorado River is a major concern in both the United States and the Republic of Mexico. The Colorado River and its tributaries supply water for about 40 million people and irrigation of...
Microbial Communities Across a Successional Gradient at Indiana Dunes National Park, 2015-2017 Microbial Communities Across a Successional Gradient at Indiana Dunes National Park, 2015-2017
This soil and vegetation data were collected along a successional gradient at the Indiana Dunes National Park. Soil samples were processed for standard soil chemistry, texture, and nutrients. DNA extracted from soil samples were analyzed for bacterial communities using 16S rRNA amplicon sequencing technique to understand the composition and distribution of these communities along the...
Hexane extractable material in water-based and oil-based drilling fluid wastes collected from sites in Oklahoma, North Dakota, and Wyoming in 2021 Hexane extractable material in water-based and oil-based drilling fluid wastes collected from sites in Oklahoma, North Dakota, and Wyoming in 2021
Wells drilled during oil and gas exploration use drilling fluids to cool and lubricate the drilling bit and clear the borehole of cuttings. These fluids are recycled during the drilling process, but eventually can no longer be used. This is an important waste stream from petroleum generation that requires disposal. Chemical characterization of these materials is important to determine if...
Data and R Code to Derive Estimates of Groundwater Levels Using MOVE.1 Regression and Compute Monthly Percentiles for Select Wells in Massachusetts Data and R Code to Derive Estimates of Groundwater Levels Using MOVE.1 Regression and Compute Monthly Percentiles for Select Wells in Massachusetts
This data release contains extended estimates of daily groundwater levels and monthly percentiles at 27 short-term monitoring wells in Massachusetts. The Maintenance of Variance Extension Type 1 (MOVE.1) regression method was used to extend short-term groundwater levels at wells with less than 10 years of continuous data. This method uses groundwater level data from a correlated long...
Conceptual headwater stream daily heat budget scenarios under varied shading and groundwater influence Conceptual headwater stream daily heat budget scenarios under varied shading and groundwater influence
The Neversink River watershed (above the Neversink Reservoir) in the Catskill Mountains of New York, USA has been a focus of U.S. Geological Survey research for decades regarding stream geochemistry, acidification, and ecology dynamics. In 2019, the Water Mission Area Next Generation Water Observing Systems Program (NGWOS) augmented the existing stream gage network to include multiscale
Predicted Physical Habitat Metrics for the Chesapeake Bay watershed at the 1:100k scale, 2001-2019 Predicted Physical Habitat Metrics for the Chesapeake Bay watershed at the 1:100k scale, 2001-2019
Degraded physical habitat is a common stressor affecting river ecosystems and a primary focus of management activities, including stream restorations. In order to assess regional conditions and help prioritize management efforts, there is an ongoing need to provide estimates of different aspects of instream physical habitat conditions at spatially continuous scales. We utilized over 16...
