Data

This data release contains structure from motion (SfM) photogrammetry products derived from high resolution aerial imagery collected on 11 and 12 January 2025 over the Defense Advanced Research Projects Agency (DARPA) Reefense hybrid oyster reef structures offshore of Tyndall Air Force Base, Florida. The imagery was collected using a Department of the Interior-owned uncrewed aerial...

This data release includes geochemistry data collected from sediments, sediment pore fluids, and high temperature hydrothermal vent fluids from the Galápagos Spreading Center. Samples were collected from Aug - Nov 2023. Data types include total carbon and nitrogen content, carbon and nitrogen stable isotopes, dissolved iron concentrations, and lipid biomarker concentrations.

This data release contains self-potential (SP) electric field data collected at the Escanaba Trough, Central Hill, in the northeast Pacific Ocean during the USGS research expedition in 2022. The datasets were gathered by the autonomous underwater vehicle (AUV) Sentry using a redundant, quasi-three-component electric field sensor with six channels. The release comprises comprehensive time...

This dataset provides wave, water level and non-tidal residual (NTR) timeseries for a reanalysis period and future projections for the mid-century. Data are available at nearshore stations across the Salish Sea and are packaged by county. Data support coastal Storm Modeling System (CoSMoS) scenarios and available for a multiple sea-level conditions (0 - 3 m).

This data release consists of flood hazard maps from compound coastal hazards--specifically sea-level rise (SLR) and projected coastal storms. Products include projected flood depths, flood extents including uncertainties, water elevations, wave heights, velocity hazard, and erosion and sedimentation pattern. These are generated using a suite of numerical models driven by outputs from...

Ferromanganese nodules and other ferromanganese coated rocks were collected using a box core from the Samoa Basin, during 2026-604-FA. This data release includes location and depth information for each box core sample, the abundance of ferromanganese minerals in each box core sample, in units of kilograms per square meter of seafloor, and geochemical data for representative samples. The...

This data release contains porewater oxygen microprofiling data from abyssal sediment cores collected from the Samoa Basin in the South Pacific Ocean within the American Samoa Exclusive Economic Zone. Sediment cores were collected from 35 locations using a box core that was subsampled with push cores. Push cores were immediately transferred to a cold laboratory van, and oxygen was...

Repeat topographic and bathymetric surveys were performed by the U.S. Geological Survey along Humboldt Bay North Spit and South Spit within the Eureka littoral cell in northern California. The surveys were used to characterize changes in coastal morphology and sand volume within an area that extends approximately 12 km north and 8 km south of the Humboldt Bay inlet. Bathymetric and...

Seafloor features identified as headward eroding mass failure scarps were digitized by hand from high-resolution multibeam bathymetry compilations (30 m grids) across the Cascadia subduction zone, which spans the region offshore of northern California, Oregon and Washington. These features were initially published by Hill et al. (2022; https://doi.org/10.1016/j.epsl.2022.117797) and here...
