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.

USGS Data for the Characterization of Radionuclides in Waste Byproducts Prior to Land Application in the United States USGS Data for the Characterization of Radionuclides in Waste Byproducts Prior to Land Application in the United States
Land applied waste byproducts were collected by USGS from 34 sites across the United States. Materials included waste byproducts from treatment of municipal sewage (biosolids), production of food (bovine, poultry, and swine wastes), and drilling of oil and gas wells (spent oil- and water-based drilling fluids). The samples represent 10 municipal wastewater treatment plants, 11 animal...
Model Archive Summary for Suspended Sediment Concentration at station 11510700, Klamath River below John C. Boyle Powerplant, near Keno, OR, October 2023 to February 2025 Model Archive Summary for Suspended Sediment Concentration at station 11510700, Klamath River below John C. Boyle Powerplant, near Keno, OR, October 2023 to February 2025
This model archive summary (MAS) and associated model calibration data contains two model evaluations: 1) a model validation of the prior-published sediment surrogate model at this site for WY 2019-2023, and 2) a new log-transformed turbidity-suspended sediment (SSC) regression model computing SSC from 01/17/2024 to 2/27/2025 following the drawdown of the John C. Boyle reservoir and...
Water-quality, bed-sediment, and invertebrate tissue trace-element data for the Clark Fork and tributaries in the upper Clark Fork Basin, Montana, October 2021-September 2022 Water-quality, bed-sediment, and invertebrate tissue trace-element data for the Clark Fork and tributaries in the upper Clark Fork Basin, Montana, October 2021-September 2022
Water, bed sediment, and invertebrate tissue were sampled in streams from Butte to near Missoula, Montana, as part of a long-term monitoring program in the upper Clark Fork Basin. The sampling program was completed by the U.S. Geological Survey (USGS), in cooperation with the U.S. Environmental Protection Agency, to characterize aquatic resources in the upper Clark Fork Basin and monitor...
Basin Characteristics for Development of Regression Equations to Estimate Flow Durations, Low-Flow Frequencies, and Mean Flows in Connecticut through Water Year 2022 Basin Characteristics for Development of Regression Equations to Estimate Flow Durations, Low-Flow Frequencies, and Mean Flows in Connecticut through Water Year 2022
The U.S. Geological Survey (USGS), in cooperation with the Connecticut Department of Energy and Environmental Protection and the Connecticut Department of Transportation, compiled a series of raster datasets for use by the USGS StreamStats application for the State of Connecticut and adjacent states. The raster datasets were used to compute basin characteristics that were used in...
Density and magnetic susceptibility measurements on Archean rocks, northwestern Minnesota, 2021 Density and magnetic susceptibility measurements on Archean rocks, northwestern Minnesota, 2021
Rock physical property measurements were collected on core samples to help understand the causative sources of gravity and magnetic survey anomalies in northwestern Minnesota. A total of 410 measurements of magnetic susceptibility and density on Archean core samples from 20 boreholes have been conducted. The measurements aid in interpretation of gravity and airborne magnetic data that...
Time-series measurements of oceanographic and seabed response data collected in Cape Cod Bay, Barnstable, MA, March 10 to April 7, 2021 Time-series measurements of oceanographic and seabed response data collected in Cape Cod Bay, Barnstable, MA, March 10 to April 7, 2021
To assess cross-shore sediment transport prediction techniques in coastal models for a wave-dominated sandy coast, the U.S. Geological Survey Woods Hole Coastal and Marine Science Center collected data to measure wave-induced and mean current water velocities near the seabed and the response of the seabed to these forces. A four-legged bottom landing frame (quadpod) containing...
Merged topography and bathymetry, Glacier Bay and Icy Strait, Alaska Merged topography and bathymetry, Glacier Bay and Icy Strait, Alaska
This work integrated multiple topographic and bathymetric data sources to generate a merged topobathymetric map of Glacier Bay, Alaska (AK) and vicinity, including Icy Strait and parts of Lynn Canal. Earlier topobathymetric sources covering the Glacier Bay region were originally developed by the National Oceanic and Atmospheric Administration (NOAA) National Centers for Environmental...
Select Borehole Data for the Salton Sea area and vicinity, Imperial-Riverside-San Diego-San Bernardino Counties, CA Select Borehole Data for the Salton Sea area and vicinity, Imperial-Riverside-San Diego-San Bernardino Counties, CA
Borehole lithology data from drillers' log descriptions were compiled for the Salton Sea area and vicinity. This data will be utilized to support hydrogeologic and hydrologic investigations. Data for some parts of the Salton Sea Watershed were already compiled for other USGS reports. These included Borrego Valley (Faunt and others, 2015), and the East Mesa (Shepherd and Rosenberg, 2024)...
Digital elevation models with elevation uncertainty treatment, Plum Island Estuary, Massachusetts, 2021 Digital elevation models with elevation uncertainty treatment, Plum Island Estuary, Massachusetts, 2021
This data release includes digital elevation models (DEMs) that were created using Monte Carlo simulations with the aim to reduce elevation overestimation in coastal wetlands at Plum Island, MA. We evaluated the performance of coastal wetland elevation refinement by using bare earth DEMs and DEMs created from the last return from the light detection and ranging (lidar) point cloud...
Everglades Vulnerability Analysis (EVA) GIS Library Everglades Vulnerability Analysis (EVA) GIS Library
The Everglades Vulnerability Analysis (EVA) is a series of connected, modular Bayesian networks that predict the response of several Everglades indicators of ecosystem health to changes in hydrology, salinity, and the landscape. EVA produces spatial explicit model outputs, and we created and compiled shapefiles to: 1) delineate boundaries that are relevant to the EVA project and 2)...

Modelled long-term wildfire occurrence probabilities in sagebrush-dominated ecosystems in the western US (1985 to 2019) Modelled long-term wildfire occurrence probabilities in sagebrush-dominated ecosystems in the western US (1985 to 2019)
Exotic annual grasses are one of the most damaging biological stressors in western North America and increase the susceptibility of landscapes to wildfire occurrence. Here we couple estimates of long-term rangeland component fractions (e.g. exotic annual grasses) with remote sensing, climate data, and machine learning techniques to estimate the long-term (1985 to 2019) probability of...
