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...
Geochemical analysis of authigenic carbonates, water column, and pore fluids measurements collected on the FK190612 research expedition in the north Pacific Ocean along the Cascadia margin in June 2019 Geochemical analysis of authigenic carbonates, water column, and pore fluids measurements collected on the FK190612 research expedition in the north Pacific Ocean along the Cascadia margin in June 2019
These are data related to the collection of samples on the FK190612 research expedition in the north Pacific Ocean along the Cascadia margin in June 2019.
Von Damm Vent Field geochemical and mineralogical data Von Damm Vent Field geochemical and mineralogical data
This data release contains geochemical data, X-ray diffractograms (XRD), inorganic carbon isotope values, and Raman spectra from rocks collected in 2020 at Von Damm vent field on the Mid Cayman Rise.
Bathymetry, topography, and sediment grain-size data from the Elwha River delta, Washington, August 2019 Bathymetry, topography, and sediment grain-size data from the Elwha River delta, Washington, August 2019
Two dams on the Elwha River, Washington State, USA trapped over 20 million m3 of sediment, reducing downstream sediment fluxes and contributing to erosion of the river's coastal delta. The removal of the Elwha and Glines Canyon dams between 2011 and 2014 induced massive increases in river sediment supply and provided an unprecedented opportunity to examine the response of a delta system...
Shoreline data for Ocean Beach, San Francisco, California, 2004 to 2021 Shoreline data for Ocean Beach, San Francisco, California, 2004 to 2021
Beach shoreline positions were derived from 221 approximately monthly beach topography surveys from 2004 through 2021 at Ocean Beach in San Francisco, California. Shoreline shapefiles for local Mean High Water (1.619m NAVD88) and local Mean Sea Level (0.975m NAVD88) were created from each survey.
Survey of sites for the presence of the nonindigenous benthic foraminifera Trochammina hadai along the west coast of North America from 1930 to 2022 Survey of sites for the presence of the nonindigenous benthic foraminifera Trochammina hadai along the west coast of North America from 1930 to 2022
Results of a survey of samples collected from 1930 to 2022 along the west coast of the United States from Alaska to San Diego, California as well as Honolulu, Hawaii for the presence of the Asian nonindigenous benthic foraminifera Trochammina hadai.
USGS Thermal Tower Reef Camera Timestack, Papaloloa, Ofu, American Samoa USGS Thermal Tower Reef Camera Timestack, Papaloloa, Ofu, American Samoa
A digital thermal camera was installed at Papaloloa reef on Ofu, American Samoa and faced west along the beach. Every minute from February 3, 2020, to August 1, 2020, the camera collected raw radiometric snapshot images. The camera is part of a U.S. Geological Survey (USGS) research project to study the effects of temperature on coral reef health. USGS researchers analyzed the timestack...
