Model of potential multiphase methane evolution in the subsurface of Southern Ontario across a wide range of initial gas contents Model of potential multiphase methane evolution in the subsurface of Southern Ontario across a wide range of initial gas contents
Numerical modeling was performed to analyze the impacts of potential multiphase conditions on long-term subsurface pressure evolution in subsurface systems. An example site on the Bruce Peninsula in Southern Ontario, Canada was selected due to the large amount of available, high-quality data showing significantly underpressured water and the possible presence of gas phase methane. The...
Database for the Geologic Map of the South Boston 30' x 60' Quadrangle, Virginia and North Carolina Database for the Geologic Map of the South Boston 30' x 60' Quadrangle, Virginia and North Carolina
The 1:100,000-scale geologic map database of the South Boston 30' x 60' quadrangle, Virginia and North Carolina, provides geologic information for the Piedmont along the I-85 and U.S. Route 58 corridors and in the Roanoke River watershed, which includes the John H. Kerr Reservoir and Lake Gaston. The Raleigh terrane (located on the eastern side of the map) contains Neoproterozoic to...
Concentrations of Perfluoroalkyl Substances in the Eggs of Brown Pelicans from Charleston, SC (2019) Concentrations of Perfluoroalkyl Substances in the Eggs of Brown Pelicans from Charleston, SC (2019)
This dataset contains concentrations of perfluoroalkyl substances (PFAS) measured in the eggs of brown pelicans nesting near Charleston, SC, USA, as well as movements of brown pelicans tracked with GPS-Platform Terminal transmitters. In total, 36 eggs were measured from three breeding colonies of brown pelicans for the presence of 24 PFAS analytes using LC-MS/MS. Concentrations were then...
Basin Characteristics Rasters for Delaware StreamStats 2020 Basin Characteristics Rasters for Delaware StreamStats 2020
This dataset was produced in by the Delaware Geological survey in cooperation with the US Geological Survey and Delaware Department of Transportation for the purpose of calculating stream gage basin characteristics in preparation for the Delaware 2020 StreamStats application. These datasets are raster representations of various environmental, geological, and land use attributes within...
Fundamental Dataset Rasters for Delaware StreamStats 2020 Fundamental Dataset Rasters for Delaware StreamStats 2020
This dataset was produced in by the Delaware Geological survey in cooperation with the US Geological Survey and Delaware Department of Transportation for the purpose of delineating gage basins and performing hydrologic analysis in the Delaware 2020 StreamStats application. These datasets are raster representations of the fundamental dataset layers necessary for the functionality of...
Bayou Dupont Marsh and Ridge Creation (BA-0048): 2016 habitat classification Bayou Dupont Marsh and Ridge Creation (BA-0048): 2016 habitat classification
The Louisiana State Legislature created the Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) in order to conserve, restore, create and enhance Louisiana's coastal wetlands. The wetland restoration plans developed pursuant to these acts specifically require an evaluation of the effectiveness of each coastal wetlands restoration project in achieving long-term solutions to...
