Database of the Geologic Map of the Greenville 1 degree x 2 degree Quadrangle, South Carolina, Georgia, and North Carolina Database of the Geologic Map of the Greenville 1 degree x 2 degree Quadrangle, South Carolina, Georgia, and North Carolina
Regional geologic investigations show that all the metamorphosed crystalline rocks underlying the Greenville 1 degree x 2 degree quadrangle are allochthonous. Seismic-reflection studies, the COCORP line (Cook and others, 1979), and the U.S. Geological Survey (USGS) seismic lines (Harris and Bayer, 1979; Harris and others, 1981) present seismic profiles across different parts of the...
Acute and chronic toxicity of two perfluoroalkyl substances to Neocloeon triangulifer Acute and chronic toxicity of two perfluoroalkyl substances to Neocloeon triangulifer
Dataset consists of 4-day, 14-day, and full life responses of laboratory cultured mayflies (Neocloeon triangulifer) to perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA). Responses were measured as survival at 4 days, 14 days, pre-emergent nymph (PEN) stage, and emergence; 14-day length; number of days to PEN stage, and imago live weight. Water quality and analytical...
Analytic-element groundwater-flow model of the Captain Jack Superfund Site, Boulder County, Colorado Analytic-element groundwater-flow model of the Captain Jack Superfund Site, Boulder County, Colorado
The U.S. Geological Survey (USGS) used an analytic-element method (AEM) modeling approach to quantitatively understand groundwater dynamics at the Captain Jack Superfund Site, located in Boulder County, Colorado. The Captain Jack Superfund Site hosts extensive interconnected underground mine workings.The U.S. Environmental Protection Agency has instituted a remedial strategy of...
Predicted Pinyon Jay (Gymnorhinus cyanocephalus) densities across the western United States, 2008-2020 Predicted Pinyon Jay (Gymnorhinus cyanocephalus) densities across the western United States, 2008-2020
Management intended to benefit a target species may also affect non-target species that co-occur over space and time. Pinyon jay (Gymnorhinus cyanocephalus) populations experienced long-term declines and rely on habitat that could be lost to conifer removal programs for greater sage-grouse (Centrocercus urophasianus). Using 13 years of point count data (2008-2020) collected across the...
Idle well fluid measurements for oil and gas wells in California Idle well fluid measurements for oil and gas wells in California
This dataset consists of 119,494 lines of data consisting of idle well fluid level depth, auxiliary measurements, and well parameters from California oil and gas wells that were reported to the California Department of Conservation, Geologic Energy Management Division (CalGEM). The dataset was provided by CalGEM in March 2018 and includes measurements made from 1976 to 2018. There are 5...
Exposure of FY2020 Federal Real Property Profile Data to 100-year and 500-year Flood Hazard Zones for the years 2022 and 2052 Exposure of FY2020 Federal Real Property Profile Data to 100-year and 500-year Flood Hazard Zones for the years 2022 and 2052
The dataset contains hazard-exposure estimates of FY2020 Federal Real Property Profile (FRPP) data to 100-year and 500-year flood-hazard zones for the years 2022 and 2052. Flow depths for each of the four hazard zones were estimated for every FRPP record using geospatial analysis. Results include raw values for estimated flow depths in centimeters and bin values on a -1 to 5 scale. Flood...
