The U.S. Geological Survey (USGS), in cooperation with the Arkansas Geological Survey (AGS), has gathered available geophysical logs and related data from the USGS office archives in Arkansas and Tennessee as a basis for developing a hydrogeologic framework for the Southeast region of the United States. Similar efforts were undertaken by the Mississippi Embayment Regional Aquifer Study (MERAS) and the Regional Aquifer-System Analysis (RASA) Program. The logs compiled for these older efforts were difficult to access from the paper files; however, and partly because of this, older and newer logs were compiled into a single digital database for the current study.

Airborne electromagnetic (AEM) and magnetic survey data were collected during March 2022 over a distance of 2,574.6 line kilometers in southeast and southwest Wisconsin. These data were collected in support of an effort to improve estimates of depth to bedrock through a collaborative project between the U.S. Geological Survey (USGS), Wisconsin Department of Agriculture, Trade, and Consumer Protection (DATCP), and Wisconsin Geological and Natural History Survey (WGNHS). Data were acquired by SkyTEM Canada Inc. with the SkyTEM 304M time-domain helicopter-borne electromagnetic system together with a Geometrics G822A cesium vapor magnetometer. The survey was acquired at a nominal flight height of 30 - 40 meters (m)...

This data release contains data associated with the Lewis Shale-Fox Hills Sandstone-Lance Formation depositional system (also referred to as the Lewis Shale system) in the eastern part of the Southwestern Wyoming Province of Wyoming and Colorado. Specifically, the data cover the Great Divide, Washakie, and Sand Wash Basins, the Wamsutter and Cherokee arches, and the Rock Springs Uplift. The Lewis Shale is underlain by the Almond Formation, overlain by the Fox Hills Sandstone, and interfingers with both formations on a regional scale. The Lewis Shale is divided into a lower, informal member, a middle, formal Dad Sandstone Member, and an upper, informal member. At the top of the lower Lewis member, there is a maximum...

This Scientific Data Release is a spatial geodatabase containing Woodruff, K.D. Christopher, M.J., 1982, Thickness of Regolith in the Delaware Piedmont: Delaware Geological Survey Open File Report No. 19, scale 1:24,000, formatted to Geologic Map Schema (GeMS) standards. These geospatial data depict the total thickness (regolith) of both the loose, transported material and the weathered rock that overlies crystalline rocks of the Delaware Piedmont. Land-use planners of many kinds (including National Forest managers, developers, city and rural planners, and highway builders) need accurate geologic data with which to make informed decisions. This geodatabase was produced in support of the U.S. Geological Survey U.S....

This describes 28 thickness point shapefiles that represent true vertical thickness (TVT) values by calculating the difference between stratigraphically adjacent formation tops picked on borehole geophysical logs. In wells where adjacent formation tops are missing, no TVT value is calculated. The TVT values are a measure of vertical thickness and do not account for the structural dip of units encountered in the wellbore. In total, the dataset contains 115,789 TVT values calculated in 16,200 wells from the Williston Basin of North Dakota, South Dakota, and Montana. This is a child item of a larger data release titled "Data release for the 3D petroleum systems model of the Williston Basin, USA".
The Cabin Branch and Cabin Creek (Cappy Avenue) outcrops are located along two small creeks in Prince George’s County, Maryland. The Cabin Branch outcrop contains exposures of silty sands of the Upper Cretaceous Severn Formation, and both outcrops contain Paleocene silty quartz and glauconitic sands of the Danian Brightseat Formation and highly fossiliferous glauconitic quartz sands of the Selandian Aquia Formation. Data from these two locations were generated in order to designate a Principal Reference Section for the Danian age Brightseat Formation. The Cabin Branch outcrop consists of disjunct exposures along an approximately 0.4-mile section of the creek. At the nearby Cabin Creek (Cappy Avenue) outcrop a more...
This USGS data release represents the data from the following publication: Prudic, D.E., and Herman, M.E., 1996, Ground-water flow and simulated effects of development in Paradise Valley, a basin tributary to the Humboldt River in Humboldt County, Nevada: U.S. Geological Survey Professional Paper 1409-F, https://doi.org/10.3133/pp1409F.
This file contains 18 gross isopach grids that represent true vertical thickness (TVT) values by calculating the difference between 19 stratigraphically adjacent horizons picked on borehole geophysical logs in the Southwestern Wyoming Province. In wells where adjacent horizons are missing, no TVT value is calculated. The TVT values are a measure of vertical thickness and do not account for the structural dip of units encountered in the wellbore. The 19 stratigraphic horizons include: top Almond Formation (base Lewis Shale), top lower Lewis Shale (base Asquith marker), top Asquith marker, top flooding surfaces F1-15, and top Fox Hills Sandstone. For more detailed stratigraphic information, please see the associated...
This file contains 15 net sand isopach grids that represent the summed true vertical thickness (TVT) of sand intervals between 15 stratigraphically adjacent horizons picked on borehole geophysical logs in the Southwestern Wyoming Province. In wells where adjacent horizons are missing, no TVT value is calculated. The TVT values are a measure of vertical thickness and do not account for the structural dip of units encountered in the wellbore. The 15 stratigraphic horizons are the tops of 15 regional flooding surfaces F1-15. Net Sand was determined by normalizing gamma ray logs and using a cut-off of 85 API units and then summing each interval. For more detailed stratigraphic information, please see the associated...
This data release includes the model input and output files for the 3D petroleum systems model of the Williston Basin. The model was created in Schlumberger's PetroMod version 2020.1. The enclosed folders are standard PetroMod format and contain all data necessary for defining and re-simulating the model. Please contact Tim Nesheim at the North Dakota Geologic Survey (tonesheim@nd.gov) directly for static temperature log data used in the temperature calibration. Proprietary IHS Markit ® (2022) data used for model calibration are also not included in this data release. This is a child item of a larger data release titled "Data release for the 3D petroleum systems model of the Williston Basin, USA".
Airborne electromagnetic (AEM) and magnetic survey data were collected during July and August 2022 over a distance of 3,588.5 line kilometers covering Delaware Bay and surrounding regipons in New Jersey and Delaware. Data were collected as part of the USGS Delaware River Basin Next Generation Water Observing Systems (NGWOS) project to improve understanding of groundwater salinity distributions near Delaware Bay. The survey was primarily funded by the USGS, with partial support through collaboration with the University of Delaware to extend data collection to parts of Rehoboth Bay and Indian River Bay. Data were acquired by SkyTEM Canada Inc. with the SkyTEM 304M time-domain helicopter-borne electromagnetic system...

This digital dataset was created as part of a U.S. Geological Survey hydrologic resource assessment and development of an integrated numerical hydrologic model of the hydrologic system of the Upper Colorado River Basin, an extensive region covering approximately 412,000 square kilometers in five states: Wyoming, Colorado, Utah, Arizona, and New Mexico. As part of this larger study, the USGS developed this digital dataset of geologic data and a three-dimensional hydrogeologic framework model (3D HFM) that define the elevation, thickness, and extent of seven hydrogeologic units in the Upper Colorado River Basin. The hydrogeologic setting of the Colorado Plateau consists of thick Paleozoic, Mesozoic, and Cenozoic aquifers,...

As part of the USGS's California State Waters Mapping Project, a 50-m grid of sediment thickness for the seafloor within the 3-nautical mile limit between Point Sur and Point Arguello was generated from seismic-reflection data collected between 2008 and 2014, and supplemented with geologic structure (fault and fold) information following the methodology of Wong (2012). Water depths determined from bathymetry data were added to the sediment thickness data to provide information on the depth to base of the post-LGM unit. Reference Cited: Wong, F. L., Phillips, E.L., Johnson, S.Y., and Sliter, R.W., 2012, Modeling of depth to base of Last Glacial Maximum and seafloor sediment thickness for the California State Waters...
