Precipitation, suspended-sediment, and water-quality data collected at U.S. Army Garrison Fort Carson and Piñon Canyon Maneuver Site, Colorado, during water years 2016-18 Precipitation, suspended-sediment, and water-quality data collected at U.S. Army Garrison Fort Carson and Piñon Canyon Maneuver Site, Colorado, during water years 2016-18
Precipitation, suspended-sediment, and water-quality data were collected by the U.S. Geological Survey (USGS) in cooperation with the U.S. Army on two bases in Colorado, U.S. Army Garrison Fort Carson and Piñon Canyon Maneuver Site, during water years 2016–18. Data were collected to assist in understanding the potential effects of military training maneuvers on water resources and water...
Assessment of Field and Laboratory Methods for the Detection and Analyses of Cyanobacteria and Cyanotoxins in Texas Reservoirs, 2020 Assessment of Field and Laboratory Methods for the Detection and Analyses of Cyanobacteria and Cyanotoxins in Texas Reservoirs, 2020
In cooperation with the Texas Commission on Environmental Quality (TCEQ), the U.S. Geological Survey (USGS) used various field and laboratory methods to determine the presence and concentration of cyanobacteria, cyanotoxins, and taste-and-odor compounds in selected Texas water bodies. This data release documents the results from water-quality samples collected from 12 water bodies in...
RTK GPS survey data in 1002 area of the Arctic National Wildlife Refuge RTK GPS survey data in 1002 area of the Arctic National Wildlife Refuge
The RTK survey, using a Trimble unit, was conducted in August 2021 in the coastal plains region (1002 area) of the Arctic National Wildlife Refuge, as part of a landscape vulnerability assessment. A total of six transects are included in the data, including five research sites and one transect collected at the camp site. Mean horizontal precision was 0.006m, mean vertical precision was 0...
Digital datasets for the hydrogeology of aquifers within the Fairport-Lyons Channel System and adjacent areas in Wayne, Ontario, and Seneca Counties, New York Digital datasets for the hydrogeology of aquifers within the Fairport-Lyons Channel System and adjacent areas in Wayne, Ontario, and Seneca Counties, New York
A study was conducted to provide detailed mapping of glacial aquifers associated with the Fairport-Lyons channel system in Wayne, Ontario, and Seneca Counties, New York. The study was part of the cooperative Detailed Aquifer Mapping Program between the U.S. Geological Survey (USGS) and the New York State Department of Environmental Conservation (NYSDEC). The objective of the study was to
Enhanced Terrain Imagery of the Wilmington 30 x 60 Minute Quadrangle from Lidar-Derived Elevation Models at 3-Meter Resolution Enhanced Terrain Imagery of the Wilmington 30 x 60 Minute Quadrangle from Lidar-Derived Elevation Models at 3-Meter Resolution
This imagery dataset consists of 3-meter resolution, lidar-derived imagery of the Wilmington 30 x 60 minute quadrangle in parts of Pennsylvania, Maryland, Delaware, and New Jersey. It also covers part of the Delaware River Basin. The source data used to construct this imagery consists of 1-meter and 3-meter resolution Lidar-derived digital elevation models (DEMs). The lidar source data...
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...
