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.

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...
MODFLOW-NWT model used for the simulation of groundwater flow and analysis of groundwater availability in the Boone and Roubidoux aquifers in northeastern Oklahoma, 1980-2017 MODFLOW-NWT model used for the simulation of groundwater flow and analysis of groundwater availability in the Boone and Roubidoux aquifers in northeastern Oklahoma, 1980-2017
The U.S. Geological Survey (USGS), in cooperation with the Oklahoma Water Resources Board (OWRB), constructed a finite-difference numerical groundwater-flow model of the Boone and Roubidoux aquifers in northeastern Oklahoma by using MODFLOW-NWT (version 1.1.4) with the Newton formulation solver to simulate groundwater flow and account for the drying and rewetting of cells within the...
Calibration data and model archive summaries for suspended-sediment, total nitrogen, and total phosphorus concentration surrogate models at USGS station 01575900, Chiques Creek near Marietta, Pennsylvania, 2021-2023 Calibration data and model archive summaries for suspended-sediment, total nitrogen, and total phosphorus concentration surrogate models at USGS station 01575900, Chiques Creek near Marietta, Pennsylvania, 2021-2023
The U.S. Geological Survey (USGS), in cooperation with the U.S. Department of Agriculture Natural Resources Conservation Service (USDA NRCS) has collected discrete stream samples for analysis of suspended-sediment, total nitrogen, and total phosphorus at the real-time streamflow and water-quality monitoring (turbidity and nitrate) station 01575900, Chiques Creek Near Marietta...
