This dataset records Cladophora and associated benthic algae, collectively Cladophora community or submerged aquatic vegetation (SAV), biomass collected during the growing season of 2022 at stations located along the U.S. shoreline of Lakes Michigan, Huron, Erie, and Ontario. It also records a variety of supporting data collected at Cladophora measurement stations. These supporting data...

This data release is companion to a manuscript entitled: "Long-term intermittent connection between the western Snake River Plain and Columbia Basin: a two-phased incision history of Hells Canyon". Here, we report the measured flow direction and compositions of clasts and detrital zircon U-Pb ages from samples collected from modern and ancestral rivers near the Lewiston Basin region. The...

This dataset contains summarized climate projection and historical climate statistics for selected extreme event and threshold‑based climate variables across the Southeast United States. Data are derived from downscaled CMIP6‑LOCA2 climate model outputs and observed historical precipitation and temperature data. Values are aggregated by U.S. state within the Southeast CONUS region and by

This data release contains a radar-based remote sensing product used to detect regions of surface change in southern Yukon Territory, Canada and southeast Alaska, United States between November 28, 2025 and December 9, 2025, based on the availability of Sentinel-1 satellite data. Much of this surface change is interpreted to have been triggered by the M7.0 Hubbard Glacier Earthquake that...

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...
