Datasheets associated with borehole sampling of surficial sediments in Northern Virginia and Southern Maryland conducted by the U.S. Geological Survey for the Federal Highways Administration Turner-Fairbanks Research Center In Situ Scour Testing Device Datasheets associated with borehole sampling of surficial sediments in Northern Virginia and Southern Maryland conducted by the U.S. Geological Survey for the Federal Highways Administration Turner-Fairbanks Research Center In Situ Scour Testing Device
This spreadsheet contains the results of open-bore auger samples collected by the U.S. Geological Survey in Maryland and Virginia for the Federal Highways Administration Turner-Fairbanks Highway Research Center. 19 sites were selected in 14 different locations across northern Virginia and southern Maryland by FBGC scientists to drill boreholes for the development of the TFHRC?s In-situ...
Grain-Size Data From Sediment Samples at Seven Mile Island, New Jersey and Rockaway Peninsula, New York Grain-Size Data From Sediment Samples at Seven Mile Island, New Jersey and Rockaway Peninsula, New York
Sediment grab samples were collected from one onshore location and 32 undisturbed locations along the seafloor around Seven Mile Island, New Jersey (NJ) and Rockaway Peninsula, New York (NY). The sediment grab samples were collected in May and June of 2021 at locations within the area where multibeam bathymetry surveys were also conducted during the same trip. All sediment samples were...
Ground-based gamma spectrometry data collected in northern Maine (Version 2.0, September 2022) Ground-based gamma spectrometry data collected in northern Maine (Version 2.0, September 2022)
Radiometric (gamma spectrometry) measurements were made during walking surveys in northern Maine using a GF Instruments Gamma Surveyor. These surveys involved recording measurement averages over 30-second intervals while holding the instrument approximately 1 meter above the ground. Locations were obtained via a handheld GPS. Data were collected over and in the vicinity of a radiometric...
Sediment trapping at "The Jaws" (TV-15): 2008, 2015, and 2018 land-water classifications Sediment trapping at "The Jaws" (TV-15): 2008, 2015, and 2018 land-water classifications
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...
Darcy flux and PFAS mass flux in groundwater at Cannon Air Force Base, Clovis, NM Darcy flux and PFAS mass flux in groundwater at Cannon Air Force Base, Clovis, NM
This United States Geological Survey (USGS) data release contains Darcy flux and mass flux of per- and polyfluoroalkyl substances (PFAS) measured using passive flux meters (PFMs) in monitoring wells associated with the Cannon Air Force Base (CAFB) in Clovis, New Mexico. The measurements were conducted by the USGS in cooperation with CAFB, the Air Force Civil Engineer Center, AECOM (an...
Survival, and growth of Neocloeon triangulifer under different test conditions in effluent style evaluations Survival, and growth of Neocloeon triangulifer under different test conditions in effluent style evaluations
Dataset consists of 4, 7, 10, and 14-day responses of laboratory cultured mayflies (Neocloeon triangulifer) to sodium chloride exposure under different test condition scenarios. Responses were measured as mortality and growth (length). Water quality and analytical chemistry results associated with toxicity data are included. Experiments included 1) testing the influence of organism age...
