This data release contains computed tomography (CT) scans, photographs, geochemistry, grain-size and total carbon analysis, X-ray fluorescence (XRF) scans, X-ray diffraction (XRD), magnetic susceptibility, and gamma-ray bulk density data of gravity cores, push cores, and sediment subsamples from those cores collected in 2022 from the Escanaba Trough vent field, Gorda Ridge, in the...
Properties of sediment collected from channels in northern San Francisco Bay, California, 2024 Properties of sediment collected from channels in northern San Francisco Bay, California, 2024
Bed sediment samples were collected from the channels of 4 sites within northern San Francisco Bay, California, USA. The channels sampled were located in Corte Madera Bay, San Pablo Bay, Grizzly Bay and Suisun Bay. Sediment samples were collected with push cores, by subsampling a Gomex box corer. Cores, which ranged in length from 2 to 6 centimeters (cm), were sectioned by depth. The top...
Sedimentary organic geochemistry data from Escanaba Trough, off the coast of northern California, collected May-June 2022 Sedimentary organic geochemistry data from Escanaba Trough, off the coast of northern California, collected May-June 2022
This data release presents organic geochemical data collected from sediments within the Escanaba Trough, a sedimented hydrothermal spreading center within the U.S. EEZ off the coast of Northern CA which contains marine minerals (USGS Field Activity 2022-621-FA). The data includes total organic carbon and total nitrogen content, stable and radioisotopes, compound specific biomarker data...
Data to Support Analyses of Shoreline Seasonal Cycles for Beaches of California Data to Support Analyses of Shoreline Seasonal Cycles for Beaches of California
Coastal shorelines commonly have recurring patterns of retreat and recovery that are related to annual patterns in wave climate. To assist with investigations of these seasonal cycles, we have analyzed shoreline position and wave data for the beaches of California to generate a series of metrics that describe the magnitude and timing of seasonal patterns of the shoreline and offshore...
Shoreline Change of Western Long Island, New York from Satellite Derived Shorelines Shoreline Change of Western Long Island, New York from Satellite Derived Shorelines
This data release contains tidally corrected shoreline positions for three sites of western Long Island, NY (Rockaway Peninsula, Long Beach, and Jones Beach Island). Both CSV files of tidally corrected shorelines and GeoJSON files of the region of interests (ROIs), transects, and reference shorelines are provided within respective zip files. Both file types are derived from CoastSeg v1.1...
Aerial imagery and structure-from-motion derived data products from a UAS survey of the debris flow at South Fork Campground, Sequoia National Park, CA Aerial imagery and structure-from-motion derived data products from a UAS survey of the debris flow at South Fork Campground, Sequoia National Park, CA
This data release presents aerial imagery and digital topography to support a geohazards assessment for an area of Sequoia National Park affected by debris flows in January 2023. Multiple atmospheric-river storms brought heavy precipitation to Sequoia National Park and the surrounding region in December 2022 and January 2023, triggering slope failures. Storm rainfall on January 9, 2023...
Geochemistry of ferromanganese crusts, nodules, and coated cobbles from seamounts in the Papahānaumokuākea Marine National Monument Geochemistry of ferromanganese crusts, nodules, and coated cobbles from seamounts in the Papahānaumokuākea Marine National Monument
Ferromanganese crusts, nodules, and coated cobbles were collected via ROV from seamounts off the coast of Hawaii and within the Papahānaumokuākea Marine National Monument (PMNM) in the Pacific Ocean during E/V Nautilus expeditions NA134 and NA138 in 2021 and 2022, respectively. Ferromanganese rock samples were sent to USGS for subsampling, major and trace element geochemical analyses...
Digital elevation models (DEMs) of the beach and nearshore in Santa Cruz, California Digital elevation models (DEMs) of the beach and nearshore in Santa Cruz, California
This data release presents digital elevation models (DEMs) derived from bathymetric and topographic measurements collected offshore of Santa Cruz, CA, from 2014 to 2024. Bathymetry data were collected using two personal watercraft (PWCs), each equipped with single-beam echosounders and survey-grade global navigation satellite system (GNSS) receivers. Topography data were collected on...
