Data

This dataset consists of one table containing whole-rock geochemistry data for 748 rocks from southcentral Alaska. All materials in the present study were analyzed by ALS Global between 2014 and 2022 using a range of different techniques, so multiple unique entries for a given element relate to different analytical methods or preparations, as detailed in accompanying metadata, and...

This data release contains the boundaries of assessment units and input data for the assessment of undiscovered oil and gas resources in the Bossier Formation within the Onshore United States and State Waters of the Gulf Coast Region. The assessment unit is the fundamental unit used in the National and Global Oil and Gas Assessment (NAGA) Project for the assessment of undiscovered oil...

The U.S. Geological Survey (USGS) Coastal and Marine Hazards and Resources Program has actively collected geophysical and sedimentological data in the northern Gulf of America (Gulf of Mexico) for several decades, including shallow subsurface data in the form of high-resolution seismic reflection profiles (HRSP). Prior to the mid-1990s, most HRSP data were collected in analog format as...

Surface sediment samples were collected from the Samoan Basin, an abyssal region in the Pacific Ocean on expedition 2026-604-FA. This region is within the U.S. Exclusive Economic Zone (EEZ) offshore American Samoa. These samples were analyzed by portable X-ray fluorometry (XRF) to measure geochemical concentrations of major, minor, and some trace elements to determine if there was any...

This dataset contains six csv files representing timeseries survivorship, before and after stress testing results, and metabolomics data from a reciprocal transplant experiment using two species of coral, Montipora capitata and Porites compressa. Data were collected from 2023 to 2025 on the Windward side of Oʻahu, Hawaii with coral being transplanted to and from two bays, Kailua Bay and...

This model application data release contains seasonal source-specific estimates of total nitrogen (TN) and total phosphorus (TP) loading in streams across the conterminous United States (263,494 reaches) for 21 years from 2000 through 2020 using a dynamic SPARROW (SPAtially Referenced Regressions On Watershed attributes) model. All model files are provided to reproduce the output...

This data release contains seasonal streamflow estimates across the conterminous United States (2,691,587 NHDPlusV2 flowlines with defined from nodes) for 21 water years from November 1999 through December 2020. Streamflow was estimated using the Enhanced unit RunOff Method (EROM) following McKay and others (2012) with updated diversion representation and extended here to include...

Nitrogen, phosphorus, and suspended-sediment loads, and changes in loads, in major rivers across the Chesapeake Bay watershed were calculated using monitoring data from the Chesapeake Bay River Input Monitoring (RIM) Network stations for the period 1985 through 2025. Nutrient and suspended-sediment loads and changes in loads were determined by applying a weighted regression approach...

This dataset contains site information and flood-frequency analysis results using station skew for 253 streamgaging stations operated by the U.S. Geological Survey (USGS) across Colorado within the Rio Grande Basin and Missouri, Arkansas-White-Red, and Upper Colorado River Basins (2- digit hydrologic unit codes 13, 10, 11, and 14, respectively). Some streamgages included in this study...

This data release provides a Geologic Map Schema (GeMS, USGS NCGMP, 2020) version of the State Geologic Map Compilation (SGMC) geodatabase of the conterminous United States (Horton and others, 2017). The SGMC provides spatial data for 48 state geologic maps that range from 1:50,000 to 1:1,000,000 scale. The GeMS version of the SGMC provides updated data for Arkansas, Mississippi...

This dataset includes georeferenced, high-resolution, airborne thermal infrared (TIR) and high-resolution true-color (RGB) imagery, a polyline shapefile of the channel centerline, a shapefile with TIR sample points for longitudinal stream temperature profile data, and a tabular file with longitudinal stream temperature profile data for the Santiam River basin and its tributaries, Oregon...

This data release includes Lake Ontario fish data from the April or spring prey fish bottom trawl survey, conducted by multiple agencies from 1978 through 2025.This survey goal is to quantify the relative abundance and population dynamics of prey or forage fishes, and in particular Alewife (Alosa pseudoharengus), which inform fisheries managers that decide on Lake Ontario predator fish...
