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.

SARS-CoV-2 Data from National Wastewater Surveillance System Surge Capacity Sampling, September 2021 SARS-CoV-2 Data from National Wastewater Surveillance System Surge Capacity Sampling, September 2021
Wastewater-based epidemiology (WBE) is used to determine the consumption of, or exposure to, chemicals or pathogens in human populations, and is conducted by collecting representative samples of untreated wastewater (influent) to quantify pathogens shed in the population served by the sampled wastewater system. The Centers for Disease Control and Prevention (CDC) and the US Department of...
Data for the Comparison of Computed Flow Through Manually Operated Water Control Structures Using Theoretical Versus Calibrated Coefficients Data for the Comparison of Computed Flow Through Manually Operated Water Control Structures Using Theoretical Versus Calibrated Coefficients
Discharge through 13 water control structures in Florida was calculated using theoretical equations and coefficients and compared to USGS-published discharge from October 1, 2007 to September 30, 2019. The two daily mean discharges were not compared for any values below 10 cubic feet per second or if (1) any alterations were made to the published discharge to account for factors such as...
Wetland burned area extent derived from Sentinel-2 across the southeastern U.S. (2016-2019) Wetland burned area extent derived from Sentinel-2 across the southeastern U.S. (2016-2019)
Wildfires and prescribed fires are frequent but under-mapped across wetlands of the southeastern United States . High annual precipitation supports rapid post-fire recovery of wetland vegetation, while associated cloud cover limits clear-sky observations. In addition, the low burn severity of prescribed fires and spectral confusion between fluctuating water levels and burned areas have...
Geoprocessing tools and scripts designed to streamline the workflow required to process map libraries for upload to the Interagency Flood Risk Management (InFRM) Flood Decision Support Toolbox (FDST) Geoprocessing tools and scripts designed to streamline the workflow required to process map libraries for upload to the Interagency Flood Risk Management (InFRM) Flood Decision Support Toolbox (FDST)
The Interagency Flood Risk Management (InFRM) team’s Flood Decision Support Toolbox is designed to accept flood map library submission from external agencies wishing to contribute to the web application. The geoprocessing of geospatial data comprising the flood map libraries follows set guidelines to facilitate the submission process to the web application. However, the InFRM team...
Biological Tissue Data Used to Evaluate Selenium Hazards in the Salton Sea Ecosystem (1984-2020) Biological Tissue Data Used to Evaluate Selenium Hazards in the Salton Sea Ecosystem (1984-2020)
In response to the rapidly evolving conditions at the Salton Sea with the emergence of both newly formed wetland habitat and increasing hazards to wildlife, the U.S. Bureau of Reclamation and U.S. Geological Survey have funded a re-evaluation of data gaps regarding selenium concentrations in biota the region. As part of this work, selenium concentrations in biological tissue samples were...
Estrogen equivalents of surface water in Pennsylvania, 2012-2017 Estrogen equivalents of surface water in Pennsylvania, 2012-2017
The data were gathered as part of a long-term, seasonal assessment of estrogenicity in selected locations within Pennsylvania from 2012-2017. Data were collected over this time frame to determine seasonal and annual changes in surface water estrogenicity.Estrogen is reported as estrogen equivalents (EEQ) as determined by a bioluminescent yeast estrogen screen. A total of 193 grab water...
