Digital photographs using a remotely piloted unoccupied aerial system and derived point clouds for bluffs in Ludington, MI, July 11, 2019, and July 14, 2021 Digital photographs using a remotely piloted unoccupied aerial system and derived point clouds for bluffs in Ludington, MI, July 11, 2019, and July 14, 2021
Images were collected using a remotely piloted unoccupied aerial system (UAS) over the bluffs of the eastern shore of Lake Michigan in Ludington rural area, Mason County, MI. Images were collected in two separate surveys conducted on July 11, 2019, and July 14, 2021, using a DJI Phantom 3 and 4 PRO commercial UAS respectively operated by the University of Toledo. The images cover an...
Digital photographs using a remotely piloted unoccupied aerial system and derived point clouds for bluffs in St. Joseph, MI, July 8, 2019 and July 13, 2021 Digital photographs using a remotely piloted unoccupied aerial system and derived point clouds for bluffs in St. Joseph, MI, July 8, 2019 and July 13, 2021
Images were collected using a remotely piloted unoccupied aerial system (UAS) over the bluffs of the eastern shore of Lake Michigan in St. Joseph rural residential area, Berrien County, MI. Images were collected in two separate surveys conducted on July 8, 2019, and July 13, 2021, using a DJI Phantom 3 and 4 PRO commercial UAS respectively operated by the University of Toledo. The images...
Digital subsurface data from previously published contour map of the top of the Wilcox Group, northern Gulf of Mexico coastal region Digital subsurface data from previously published contour map of the top of the Wilcox Group, northern Gulf of Mexico coastal region
The lower Paleogene Wilcox Group crops out around the northern edge of the Gulf of Mexico Basin and is a major coal-bearing unit and a primary oil and gas producer in the lower Paleogene section of the Gulf Coast region. The outcrop distribution of the Wilcox Group and other coal-bearing strata of the Gulf Coast region was compiled as part of a U.S. Geological Survey National Coal...
Digital subsurface data from previously published contoured maps of the top of the Dakota Sandstone, Uinta and Piceance basins, Utah and Colorado Digital subsurface data from previously published contoured maps of the top of the Dakota Sandstone, Uinta and Piceance basins, Utah and Colorado
The top of the Upper Cretaceous Dakota Sandstone is present in the subsurface throughout the Uinta and Piceance basins of UT and CO and is easily recognized in the subsurface from geophysical well logs. This digital data release captures in digital form the results of two previously published contoured subsurface maps that were constructed on the top of Dakota Sandstone datum; one of the...
Digital subsurface data from previously published maps of the base and thickness of post-Eocene continental deposits in the Sacramento Valley, California Digital subsurface data from previously published maps of the base and thickness of post-Eocene continental deposits in the Sacramento Valley, California
Post-Eocene (predominantly Pliocene) continental sedimentary rocks of the Sacramento Valley, CA are up to 1,200 m thick beneath the valley. These rocks contain most of the fresh ground water in the valley, forming a key component of the total water budget for the valley. A 1974 study by the U.S. Geological Survey was an early attempt to develop detailed knowledge of the subsurface...
Digital subsurface database of previously published well tops, structural features, and contour maps of the Inyan Kara Group, Minnekahta Formation, Minnelusa Formation, Madison Group, and Deadwood Formation, Black Hills region, South Dakota and Wyoming Digital subsurface database of previously published well tops, structural features, and contour maps of the Inyan Kara Group, Minnekahta Formation, Minnelusa Formation, Madison Group, and Deadwood Formation, Black Hills region, South Dakota and Wyoming
This digital data release presents multiple previously published elements of the structural configuration of the Black Hills regional subsurface. The original data within this geodatabase is sourced from multiple U.S. Geological Survey Open File Reports into the hydrology of the Black Hills, stored on the USGS Water Mission Area NSDI Node (Driscoll, 1992; Strobel et al., 1999; Williamson...
Digital Terrain Model to Support Modeling of Lahars Originating on the West Side of Mount Rainier, Washington Digital Terrain Model to Support Modeling of Lahars Originating on the West Side of Mount Rainier, Washington
This digital elevation model contains ground surface elevations for the valleys of rivers draining the west side of Mount Rainier, Washington. Elevations are mostly from the 1/9th arc-second (approximately 3 meter) resolution U.S. Geological Survey National Elevation Dataset (NED). The NED data were projected to the Universal Transverse Mercator Zone 10 coordinate system and mosaicked to...

This data set is a compilation of discrete and high frequency water quality data from sites on Allequash Creek in Wisconsin, and within the Allequash Creek watershed, for the water years (WY) 2019-2021.
Dissolved arsenic, copper, and lead concentrations in surface water within the Klamath Basin (ver. 3.0, October 2022) Dissolved arsenic, copper, and lead concentrations in surface water within the Klamath Basin (ver. 3.0, October 2022)
Arsenic (As) toxicity is a global environmental and health problem. There are both natural (eg volcanic activity) and anthropogenic sources of As (eg lead arsenate and copper arsenate were commonly used pesticides in the 1900's). Aqueous levels of arsenic in the Klamath Basin (CA, OR), which has a volcanic origin, can exceed at some locations both the Oregon Department of Environmental...
Dissolved organic carbon, total petroleum hydrocarbons and and toxicity assay results for Bemidji, MN (2018) Dissolved organic carbon, total petroleum hydrocarbons and and toxicity assay results for Bemidji, MN (2018)
In crude-oil-contaminant plumes the dissolved organic carbon (DOC) is mainly hydrocarbon degradation intermediates only partly quantified by the diesel range total petroleum hydrocarbon (TPHd) method. To understand potential biological effects of degradation intermediates we tested three fractions of DOC: (1) solid phase extract (HLB); (2) dichloromethane (DCM-total) extract used in TPHd...
