Luminescence, charcoal abundance, and radiocarbon data for: Geochronologic data reveal late Pleistocene to Holocene debris-flow history and wildfire association within Whiskeytown National Recreation Area, Klamath Mountains, northern California Luminescence, charcoal abundance, and radiocarbon data for: Geochronologic data reveal late Pleistocene to Holocene debris-flow history and wildfire association within Whiskeytown National Recreation Area, Klamath Mountains, northern California
This report summarizes the dating results from sedimentary deposits sampled by the National Park Service and the U.S. Geological Survey and analyzed at the USGS Luminescence Geochronology Laboratory. Within this report, we detail the luminescence measurement, equivalent dose determination, and dating-related calculations. We recommend that this report be included as the supplementary...
Digital drillhole lithologic data and a radiocarbon age -- data supporting interpretation of Quaternary depositional history in the vicinity of Fort Morgan, Eastern Colorado Digital drillhole lithologic data and a radiocarbon age -- data supporting interpretation of Quaternary depositional history in the vicinity of Fort Morgan, Eastern Colorado
This data release contains digital location and downhole lithologic data for 3,564 drillholes from along a portion of the South Platte River in eastern Colorado. The drillholes are located within the east half of the Greeley and the west half of the Fort Morgan USGS 1:100,000 scale maps. Subsurface lithologic data is intended to extend the results of surficial geologic mapping to the...
Luminescence data for: Reconstructing the Quaternary depositional history using geologic mapping and a 3D model of the subsurface in the vicinity of Fort Morgan, Eastern Colorado Luminescence data for: Reconstructing the Quaternary depositional history using geologic mapping and a 3D model of the subsurface in the vicinity of Fort Morgan, Eastern Colorado
Centered on Fort Morgan, Colorado, this study is intended to build from previous work by adding a three-dimensional (3D) view of the subsurface to better understand the depositional history of Quaternary deposits. A 1:100,000 scale geologic map was made by combining previous geologic maps, regional soil maps, and recent field investigations. In addition to the geologic mapping, drill...
Geologic Radon Potential Map of the United States Geologic Radon Potential Map of the United States
Radon is an odorless and invisible radioactive gas that is naturally released from rocks, soil, and water. According to the U.S. Environmental Protection Agency (EPA) and the U.S. Surgeon General, radon is the second leading cause of lung cancer in the United States. Recent epidemiological studies have also identified linkages between radon exposure and cerebrovascular diseases including...
Luminescence data for: Trench Exposures across the Dead Coyote fault scarp in Kittitas Valley, Washington Luminescence data for: Trench Exposures across the Dead Coyote fault scarp in Kittitas Valley, Washington
The Wallula fault zone is an integral feature of the Olympic-Wallowa lineament, an ∼500-km-long topographic lineament oblique to the Cascadia plate boundary, extending from Vancouver Island, British Columbia, to Walla Walla, Washington. The structure and past earthquake activity of the Wallula fault zone are important because of nearby infrastructure, and also because the fault zone...
Data release for integrating remotely sensed surface water dynamics in hydrologic signature modeling Data release for integrating remotely sensed surface water dynamics in hydrologic signature modeling
Variability in river discharge, particularly very high flow and low flow conditions, has far-reaching environmental and economic consequences. The retention of water in surface storage, concentrated in lakes, ponds, wetlands, floodplains, and temporary water in flood prone areas, can potentially contribute to flow generation and flood regulation. However, the impact of surface water...
Digital data for a 3D geologic model of the Michigan Basin region, Illinois, Indiana, Michigan, Ohio, and Wisconsin, USA Digital data for a 3D geologic model of the Michigan Basin region, Illinois, Indiana, Michigan, Ohio, and Wisconsin, USA
This digital GIS dataset and accompanying nonspatial files synthesize model outputs from a regional-scale volumetric 3D geologic model that portrays the generalized subsurface geology of the Michigan Basin region of Michigan, Wisconsin, Illinois, Indiana, and Ohio. The intent of this product is to rapidly and efficiently synthesize large quantities of geologic data from a wide variety of...
Uncrewed Aircraft System (UAS) imagery and data products from a multiscale remote sensing field campaign at a biocrust monitoring site located near Castle Valley, Utah in February 2022 Uncrewed Aircraft System (UAS) imagery and data products from a multiscale remote sensing field campaign at a biocrust monitoring site located near Castle Valley, Utah in February 2022
In February 2022, the U.S. Geological Survey (USGS) National Uncrewed Systems Office (NUSO) conducted uncrewed aircraft systems (UAS) remote sensing flights to support biological soil crust (biocrust) research at an experiment site located near Castle Valley, Utah. Researchers at the USGS Southwest Biological Science Center have managed this site for over 50 years to study the effects of
Data release for Effects of Total Suspended Solids on Photomineralization of Dissolved Organic Matter in the Peace-Athabasca Delta, Canada Data release for Effects of Total Suspended Solids on Photomineralization of Dissolved Organic Matter in the Peace-Athabasca Delta, Canada
Northern deltas receive chromophoric dissolved organic matter (CDOM) from their watersheds, which can be oxidized to carbon dioxide upon absorption of sunlight (i.e., photomineralized). These deltas also receive total suspended solids (TSS), which may shade sunlight absorption by CDOM, thus limiting photomineralization. To quantify this interaction for the first time, we measured
Bedrock geologic map database for the Aztec 1-degree x 2-degree quadrangle, northern New Mexico and southern Colorado Bedrock geologic map database for the Aztec 1-degree x 2-degree quadrangle, northern New Mexico and southern Colorado
This data release presents geologic map data for the bedrock geology of the Aztec 1-degree by 2-degree quadrangle, New Mexico. Geologic mapping incorporates new interpretive contributions and compilation from published geologic map data sources primarily ranging from 1:24,000 to 1:50,000 scale. Much of the geology incorporated from published geologic maps is adjusted based on digital...
Detrital zircon U-Pb data for paleontological localities in the Piceance Creek Basin Detrital zircon U-Pb data for paleontological localities in the Piceance Creek Basin
This data release hosts detrital zircon U-Th-Pb geochronology data that were created to support geologic mapping and research in the context of the Geologic Framework of the Intermountain West Project supported by the National Cooperative Geologic Mapping Program. These data characterize the deposition age and provenance of Cretaceous stratigraphic units exposed in the Piceance Creek...
