Data

This data release provides a list of published data releases that contain coal exploration drill-hole lithologic, geophysical, and geochemical data from drilling locations in several U.S. States. The text (TXT) file associated with this data release lists the State data releases that are available. The text file will be updated as additional drill-hole data releases are published. The...

Coal exploration drill-hole lithologic, geophysical, and geochemical data from 657 drilling locations in the western Kentucky Mississippi embayment area are provided in this data release. Eighteen drilling locations have multiple sets of data files. The wells are located in eight counties (Ballard, Calloway, Carlisle, Fulton, Graves, Hickman, Marshall, and McCracken) and were drilled...

As part of the restoration monitoring component of the Deepwater Horizon early restoration project, scientists from the U.S. Geological Survey St. Petersburg Coastal and Marine Science Center (USGS SPCMSC) conducted single-beam and multibeam bathymetry surveys around Breton Island, Louisiana (LA), from August 5-10, 2024, for Field Activity Number (FAN) 2024-320-FA. The purpose of data...

In June 2025, the U.S. Geological Survey St. Petersburg Coastal and Marine Science Center (USGS SPCMSC) participated in a multidisciplinary geoscientific field data collection within Midnight Pass and Milton Pass located along Florida’s west-central coastline, which opened as a result of hurricanes Helene and Milton in 2024. Researchers with the Nearshore Extreme Events Reconnaissance...

The Louisiana State Legislature established the Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) to conserve, restore, create and enhance Louisiana's coastal wetlands. Restoration plans developed under CWPPRA require evaluating the effectiveness of each project in achieving long-term solutions to coastal wetlands loss. This data set includes mosaicked aerial photographs...

To assess historical environment changes associated with changes in hydrologic connection to the Gulf Intracoastal Waterway (GIW) and Mobile Bay, six sediment cores (50-80 cm in length) were collected in 2021 from two coastal wetland sites. These two sites in Gulf Shores, Alabama were: Oyster Bay Nature Preserve ("OB", a brackish marsh with natural hydrology) and the Emmet O. and Vina...

This dataset presents a recalculated compilation of geochronology ages of Cretaceous-Miocene intrusive rocks and volcanic plugs in the northern Rocky Mountains USA, with a focus on Montana and Idaho. Mineral assessments and prospectivity mapping requires detailed spatiotemporal understanding of magma systems in the upper crust to predict when and where ore deposits may have formed...

This data release provides the concentration and quality-assurance results for inorganic constituents analyzed in water-quality samples from 26 residential and commercial tapwater locations in Montana by the U.S. Geological Survey (USGS) Environmental Health Program (EHP), Tapwater Exposure Study. The samples were collected between June 10-12, 2024, from both public supply (8) and...

This data release contains the concentration results of per- and polyfluoroalkyl substances (PFAS) collected in fish tissue and whole blood, bed sediment and biofilm samples from water bodies in and surrounding the Little Bighorn River (LBHR) in Montana in July 2023. A total of 29 filets and whole blood samples were collected from 10 brown trout, 10 catfish, 6 rock bass, and 3 goldeye...

A collaborative effort with US Fish and Wildlife Services is underway with the goal of reducing the spread of flea contracted plague in prairie dog (Cynomys spp.) colonies across the US. One method of flea reduction being studied involves spreading bait pellets containing insecticides commonly used for flea control around prairie dog habitats. To better understand the effectiveness of...

This data release contains nutrient, metal, hormone, pharmaceutical, dioxin, and furan concentration data and field readings associated with surface water samples collected from 35 locations along the New York shoreline of Lake Ontario and surrounding tributaries. Samples were collected from April 2023 through October 2023 at nearshore, embayment, and tributary sites from Niagara River...

This U.S. Geological Survey (USGS) data release contains groundwater quality data for twelve wells in Suffolk County, New York and associated quality assurance results. Samples were collected between 2021 and 2023 and analyzed for per- and polyfluoroalkyl substances (PFAS), pesticides, and pharmaceuticals. Measurements of pH, specific conductance, dissolved oxygen, water temperature and...
