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.

Data on the detection of Epioblasma capsaeformis using a designed environmental DNA (eDNA) survey upstream and downstream of known populations in the Clinch River, Tennessee (2019 to 2021) Data on the detection of Epioblasma capsaeformis using a designed environmental DNA (eDNA) survey upstream and downstream of known populations in the Clinch River, Tennessee (2019 to 2021)
Data describe a designed environmental DNA (eDNA) survey for the detection of oyster mussel (Epioblasma capsaeformis) from field collected water samples. Parameters described include the limit of detection and limit of quantification of the assay; a list of freshwater mussel species tissue samples that were used to test specificity of the assay; and field collected water samples that...
2021 USGS Phragmites australis Greenhouse Submergence Experiment Data conducted in Ann Arbor, MI 2021 USGS Phragmites australis Greenhouse Submergence Experiment Data conducted in Ann Arbor, MI
To determine the potential for controlling non-native Phragmites australis through use of a cut-to-drown management strategy we performed a controlled greenhouse mesocosm experiment in Ann Arbor, MI during summer 2021. Field collected Phragmites rhizomes from one site within Michigan were propagated, cuttings taken of individual stems and potted in nursery pots. Established plants were...
Tephra geochemistry of the Ibex Hollow Tuff, a 12-Ma super-eruption Tephra geochemistry of the Ibex Hollow Tuff, a 12-Ma super-eruption
These tables contain geochemical data collected for tephra samples either correlated with or in the same type section with the Ibex Hollow Tuff. Most samples were collected by Andrei Sarna-Wojcicki and Mike Perkins, but some were submitted to the U.S. Geological Survey Tephrochronology Project for analysis by other persons. Electron microprobe analysis (EMA) was performed at the U.S...
Sulfide Electron Microprobe Analyses and Petrography of Mineralized Samples from the Stratabound Sheep Creek Sediment-Hosted Zn-Pb-Ag-Sn Prospect, and SHRIMP U-Pb Zircon Data for Metaigneous Rocks in the Bonnifield Mining District, Healy Quadrangle, AK Sulfide Electron Microprobe Analyses and Petrography of Mineralized Samples from the Stratabound Sheep Creek Sediment-Hosted Zn-Pb-Ag-Sn Prospect, and SHRIMP U-Pb Zircon Data for Metaigneous Rocks in the Bonnifield Mining District, Healy Quadrangle, AK
This data set contains 99 electron microprobe analyses of cassiterite, chalcopyrite, galena, pyrite, sphalerite, and tetrahedrite from seven Sheep Creek drill core samples and one outcrop; and a table that describes the textures, mineralogy, and rock type of 15 thin sections of Sheep Creek drill core and observations from our study and from drill core logging by industry. These data were...
USGS National Shoreline Change - A GIS compilation of new lidar-derived shorelines (2010, 2017, and 2018) and associated shoreline change data for coastal South Carolina USGS National Shoreline Change - A GIS compilation of new lidar-derived shorelines (2010, 2017, and 2018) and associated shoreline change data for coastal South Carolina
The U.S. Geological Survey (USGS) has compiled national shoreline data for more than 20 years to document coastal change and serve the needs of research, management, and the public. Maintaining a record of historical shoreline positions is an effective method to monitor national shoreline evolution over time, enabling scientists to identify areas most susceptible to erosion or accretion...
Database of Trends in Vegetation Properties and Climate Adaptation Variables on the San Carlos Apache Reservation and Upper Gila River Watershed (1935-2021) Database of Trends in Vegetation Properties and Climate Adaptation Variables on the San Carlos Apache Reservation and Upper Gila River Watershed (1935-2021)
We apply a research approach that can inform riparian restoration planning by developing products that show recent trends in vegetation conditions identifying areas potentially more at risk for degradation and the associated relationship between riparian vegetation dynamics and climate conditions. The vegetation is characterized using a series of remote sensing vegetation indices...
