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.

Annual burn severity mosaics for the southeastern United States (2000-2022) Annual burn severity mosaics for the southeastern United States (2000-2022)
The southeastern United States experiences frequent wild and prescribed fire activity. Mapped burn severity products in the southeastern U.S. face challenges accurately characterizing fire effects due to rapid post-fire recovery limiting observation windows, limited availability of cloud-free imagery, spectral confusion within wetland areas, and operational constraints. As mapped burn...
Water Quality and Toxic Algal Presence in Burrow Pits in Eastern Lake Pontchartrain: 2021-2023 Water Quality and Toxic Algal Presence in Burrow Pits in Eastern Lake Pontchartrain: 2021-2023
This dataset consists of sensor profile and water sample results from monitoring campaign to investigate the effects of two dredged pits in eastern Lake Pontchartrain on dissolved oxygen conditions within the water column in and surrounding the pits over a three-year period. The borrow pits were excavated to provide soil material to nourish three nearby protected marsh sites: Bayou...
Low flow water quality data for the Animas River, Arrastra Creek to Silverton, Colorado, September 2021 Low flow water quality data for the Animas River, Arrastra Creek to Silverton, Colorado, September 2021
A synoptic sampling campaign was conducted on the Animas River near Silverton, Colorado, under low-flow conditions in September 2021. The sampling campaign was designed to quantify constituent loading and identify sources of contamination along a 3.8-kilometer study reach. The study reach began approximately 170 meters upstream of Arrastra Creek and extended downstream to U.S. Geological...
Self-potential and electric resistivity tomography data pertaining to groundwater flow for thermal springs, Hot Springs National Park, Arkansas, February 2023–January 2024 Self-potential and electric resistivity tomography data pertaining to groundwater flow for thermal springs, Hot Springs National Park, Arkansas, February 2023–January 2024
This data release contains self-potential (SP) map data, two-dimensional electrical resistivity tomography (ERT) data, and time-lapse SP-monitoring data measured within the thermal springs discharge area of Hot Springs National Park in Hot Springs, Arkansas, in addition to the geospatial coordinates of each geophysical measurement and photographs of the reconnaissance and monitoring...
Spatial profiles of waterborne self-potential and water-quality-property data acquired September 8–11, 2023, in Elm and Hartwell Brooks and the Shawsheen River near Hanscom Air Force Base, Bedford, Massachusetts, to identify groundwater seepage locations. Spatial profiles of waterborne self-potential and water-quality-property data acquired September 8–11, 2023, in Elm and Hartwell Brooks and the Shawsheen River near Hanscom Air Force Base, Bedford, Massachusetts, to identify groundwater seepage locations.
This data release contains geophysical and water-quality property data measured by the U.S. Geological Survey (USGS) along downstream continuous profiles in surveyed reaches of Elm Brook, Hartwell Brook, and the Shawsheen River near Hanscom Air Force Base in Bedford, Massachusetts. The geophysical data consist of spatial profiles of waterborne self-potential (WaSP) voltages attributed to...
BEWARE2 database: A meta-process model to assess wave-driven flooding hazards on morphologically diverse, coral reef-lined coasts BEWARE2 database: A meta-process model to assess wave-driven flooding hazards on morphologically diverse, coral reef-lined coasts
This dataset contains the reef profiles and resulting hydrodynamic outputs of the "Broad-range Estimator of Wave Attack in Reef Environments" (BEWARE-2) meta-process modeling system. A process-based, wave-resolving hydrodynamic model (XBeach Non-Hydrostatic+, "XBNH+") was used to create a large synthetic database for use in BEWARE-2, relating incident hydrodynamics and coral reef...
