Exposure to surface water supply and use imbalance during spawning months for 214 fish taxa across the conterminous United States Exposure to surface water supply and use imbalance during spawning months for 214 fish taxa across the conterminous United States
This data release contains the output from an ecological analysis modeling the exposure of 214 fish taxa across the conterminous US (CONUS) to an index of surface water supply and use imbalances (SUI), a metric of monthly gross average water supply available after accounting for climate variation and consumptive use, during their spawning months, hereafter referred to as spawning...
Extrapolated Offshore Occupancy Predictions for Three Bat Species Extrapolated Offshore Occupancy Predictions for Three Bat Species
We generated an extrapolated surface of predicted occupancy values offshore for the little brown bat (Myotis lucifugus), northern long-eared bat (Myotis septentrionalis), and tri-colored bat (Perimyotis subflavus). Values were generated for each grid cell in the Continental United States (CONUS) Grid-Based Offshore Sampling Frame which extends from coastal areas (i.e., 10 kilometer [km]...
Extreme Flood, Atmospheric River Presence, and Basin Characteristic Data for a Study of Peak Streamflow Special Conditions in Alaska Extreme Flood, Atmospheric River Presence, and Basin Characteristic Data for a Study of Peak Streamflow Special Conditions in Alaska
This data release contains input data and results for an investigation of special conditions for peak streamflow and extreme floods for USGS streamgages in Alaska. Special conditions can include data-collection conditions, basin conditions, flood-generating mechanisms, or other information and can be critical for informing hydrologic analyses such as flood frequency analysis. The dataset...
Fairfax County Monitoring Network 2007 - 2022: Annual Loads, Regression Models, and Ancillary Data Fairfax County Monitoring Network 2007 - 2022: Annual Loads, Regression Models, and Ancillary Data
Nitrogen (N), phosphorus (P), and suspended sediment (SS) loads in Fairfax County, Virginia streams were calculated using monitoring data from 5 intensively monitored watersheds for the period from water year (October - September) 2008 through 2022. Nutrient (N and P) and SS loads were computed using a surrogate (multiple-linear regression) approach with lab analyzed N, P, and SS samples...
Federal and Indian lands coal and other mineral production, value, and royalties by state, 1954-1980 and prior Federal and Indian lands coal and other mineral production, value, and royalties by state, 1954-1980 and prior
This data release includes a digitized version of the "Statistics by States, lands, products and years" section of the 1981 edition of the Federal and Indian lands coal, phosphate, potash, sodium, and other mineral production, royalty income, and related statistics publication. These data were published by the Conservation Division of the U.S. Geological Survey, which was tasked with the

Feeding and Trophic Ecology of Invasive Blue Catfish Ictalurus furcatus in an Eastern shore tributary of the Chesapeake Bay Feeding and Trophic Ecology of Invasive Blue Catfish Ictalurus furcatus in an Eastern shore tributary of the Chesapeake Bay
This study investigates the feeding and trophic ecology of invasive Blue Catfish (Ictalurus furcatus) in the Nanticoke River watershed on the Chesapeake Bay’s Eastern Shore (Maryland, U.S.A). From a total of 1,032 stomach samples collected, a subset of 88 was analyzed using 18S and COI metabarcoding primers to enhance taxonomic resolution of prey items. USGS-generated genetic reference...
Field evidence noted in 2008 to 2023 that pertains to sea floods of the past millennium on Anegada, British Virgin Islands Field evidence noted in 2008 to 2023 that pertains to sea floods of the past millennium on Anegada, British Virgin Islands
This release provides inventories of georeferenced evidence pertaining to extreme waves on Anegada, a low Caribbean island perched south of the Puerto Rico Trench: CORAL BOULDERS AND COBBLES -- Derived offshore, found inland. Boulder star coral Orbicella franksii (37 localities), brain coral Pseudodiploria strigosa (171), elkhorn coral Acropora palmata (36), mustard hill coral Porites...
Field measurements of water depth and remotely sensed data from the Mulchatna River, Alaska, collected July 12-August 14, 2024 Field measurements of water depth and remotely sensed data from the Mulchatna River, Alaska, collected July 12-August 14, 2024
This data release provides field measurements of water depth and aerial and satellite images from the Mulchatna River in Alaska. These data were used to assess the feasibility of mapping the bathymetry of this remote, proglacial river, located in Lake Clark National Park and Preserve, using several depth retrieval algorithms. This approach could facilitate geomorphic and habitat...
Field Observations of Past Debris Flows, February 2024, Chuuk State, Federated States of Micronesia Field Observations of Past Debris Flows, February 2024, Chuuk State, Federated States of Micronesia
Landslide hazards pose a significant threat to communities and infrastructure across the Federated States of Micronesia (FSM). To support hazard assessment and mitigation efforts, the USGS Landslide Disaster Assistance Team (LDAT) produced landslide susceptibility and debris-flow runout models and map products for Chuuk State, FSM. For more information on the LDAT FSM project, refer to...
