Digital database of previously published subsurface unit tops from the three-dimensional geologic model used for the 2003 National Oil and Gas Assessment of the San Joaquin Basin Province, California Digital database of previously published subsurface unit tops from the three-dimensional geologic model used for the 2003 National Oil and Gas Assessment of the San Joaquin Basin Province, California
This data release provides digital geospatial data related to the three-dimensional geologic model (Hosford Scheirer, 2013) that was used as a framework for conducting the 2003 oil and gas assessment of the San Joaquin Basin province, California (Gautier and others, 2004; Hosford Scheirer, ed., 2007). The data release includes raster GeoTIFF files of the tops of the 15 composite geologic...
Digital Elevation Model and Derivative Datasets to Support the Integration of Stormwater Drainage into the StreamStats Application for the Neponset River Watershed, Massachusetts Digital Elevation Model and Derivative Datasets to Support the Integration of Stormwater Drainage into the StreamStats Application for the Neponset River Watershed, Massachusetts
This data release contains the 1-meter resolution digital elevation model (DEM; DEM.tif) and two other derivative rasters that support the U.S. Geological Survey StreamStats application’s ability to produce on-the-fly watershed delineations (https://www.usgs.gov/streamstats). The flow direction raster (fdr.tif) indicates the directionality of flow as it exits each raster cell. If a cell...
Digital elevation models for the South Atlantic Bight with elevation uncertainty treatment, overview Digital elevation models for the South Atlantic Bight with elevation uncertainty treatment, overview
This data release includes digital elevation models (DEMs) with elevation uncertainty treatment of the South Atlantic Bight. The DEMs were created using Monte Carlo simulations targeted towards limiting overestimation in elevation. For each DEM, we used Monte Carlo simulations with 1,000 iterations to create new DEM realizations. We then summarized the 1,000 DEM realizations by...
Digital elevation, flow-direction, flow-accumulation, and streamline rasters for Texas StreamStats Digital elevation, flow-direction, flow-accumulation, and streamline rasters for Texas StreamStats
The U.S. Geological Survey (USGS), in cooperation with the Texas Department of Transportation (TxDOT), prepared hydro-conditioned geographic information systems (GIS) data layers for use in the Texas StreamStats application (U.S. Geological Survey, 2026). This data release contains digital elevation, flow-direction, flow-accumulation, and streamline raster datasets at a 3-meter...
Digital input data and model output for a three-dimensional hydrogeologic framework for the Great Basin carbonate and alluvial aquifer system of Nevada, Utah, and parts of adjacent states Digital input data and model output for a three-dimensional hydrogeologic framework for the Great Basin carbonate and alluvial aquifer system of Nevada, Utah, and parts of adjacent states
This digital dataset was created as part of a U.S. Geological Survey (USGS) regional groundwater assessment of the eastern Great Basin; the project was called the Great Basin Carbonate-Alluvial Aquifer Study (GBCAAS). The study area has a geographic extent of 110,000 square miles, predominantly in eastern Nevada and western Utah. As part of this larger study, the USGS developed digital...
Digital orthophotographs and field measurements of flow velocity and depth from the Yukon and Tanana Rivers, collected July 1-3, 2025 Digital orthophotographs and field measurements of flow velocity and depth from the Yukon and Tanana Rivers, collected July 1-3, 2025
This data release includes digital orthophotos acquired from a fixed-wing aircraft and field measurements of flow velocity and depth from the Tanana and Yukon Rivers, Alaska, obtained July 1 - 3, 2025. This parent data release includes links to child pages for the data sets produced during the study (see child item links below): 1. Digital orthophotos of the Tanana and Yukon Rivers in...
Digital Surface Model and Orthoimagery of Redoubt Volcano, Lake Clark National Park, Alaska Digital Surface Model and Orthoimagery of Redoubt Volcano, Lake Clark National Park, Alaska
Aerial photography surveys of Redoubt Volcano in Lake Clark National Park, Alaska, were conducted on August 8 and September 26, 2019, by fixed-wing aircraft to generate updated elevation data and high-quality orthoimagery. The surveys were flown by the National Park Service (NPS) Alaska Regional Office (AKRO) in partnership with the United States Geological Survey (USGS) Alaska Volcano...
Discrete surface water hyperspectral data, South San Francisco Bay Discrete surface water hyperspectral data, South San Francisco Bay
Mercury pollution is a concern in aquatic environments where it binds to particles, is methylated, and bioaccumulates in food webs. In systems like San Francisco Bay that have a history of mercury contamination from mining, gold extraction, and industrial activity, tracking mercury in surface waters is critical. We developed the Mercury Mapping and Assessment Pipeline (HgMAP), a novel...
Displacement and groundwater pressure data from the Carmel Knoll and Johnson Creek landslides, Oregon, USA Displacement and groundwater pressure data from the Carmel Knoll and Johnson Creek landslides, Oregon, USA
Coastal landslides such as the Carmel Knoll and Johnson Creek landslides located in Lincoln County, Oregon, reactivate during most winter rainy seasons when groundwater pressures are elevated. We collected landslide displacement and groundwater pressure head data at 15-minute to 60-minute intervals using solar- and battery-powered dataloggers at the aforementioned landslides to assist...
DNA amplicon sequences from periphyton collected in dry RNA-preserving salts and homogenized once or multiple times DNA amplicon sequences from periphyton collected in dry RNA-preserving salts and homogenized once or multiple times
Periphyton samples were collected at Sequoia National Park (Three Rivers, California) and preserved in RNA-preserving salts mixed with river water. Samples were homogenized one, two, three, or four times for 2 minutes each, to test efficacy of different degrees of homogenization. DNA from each homogenate was extracted using the AllPrep PowerFecal Pro DNA/RNA kit (Qiagen), and the DNA...
Donkey location data and disease exposure data in southern California between 2020 and 2022 Donkey location data and disease exposure data in southern California between 2020 and 2022
This dataset includes GPS locations of free-roaming donkeys (Equus asinus; also called burros) in southern California, USA, within Fort Irwin National Training Center and Death Valley National Park between 2020 and 2022, as well as data on the disease status of donkeys in these same areas. Data were collected by placing GPS collars on donkeys and tracking their movements. Collars...
