Data
The Coastal and Marine Hazards and Resources Program is an innovator in mapping, field studies, data collection, and laboratory analyses, whose expertise is sought by other governmental agencies, educational institutions, and private companies. In turn, we seek collaborative research and development opportunities with similar groups.

Peat Thickness Measurements from Grand Bay, Mississippi and Alabama Peat Thickness Measurements from Grand Bay, Mississippi and Alabama
Location and elevation data were collected along with peat auger cores during six U.S. Geological Survey (USGS) field activities from 2013-2018 in and around Grand Bay, Mississippi (MS) and Alabama (AL) and used by Smith and others (2024). Peat auger cores were described, photographed, and the thickness of the peat unit was measured with a measuring tape. Following collection, the...
Short-Lived Radium-Isotope (Radium-223 and -224) Specific Activity for Samples Collected Between November 2022 and March 2024 Along the West Florida Shelf (Indian Rocks Beach, Nature Coast, and Venice Headland) Short-Lived Radium-Isotope (Radium-223 and -224) Specific Activity for Samples Collected Between November 2022 and March 2024 Along the West Florida Shelf (Indian Rocks Beach, Nature Coast, and Venice Headland)
In 2021, a collaborative scientific investigation (National Science Foundation Grant Award OCE-2148989, Project 880516) was started for the purpose of quantifying shelf inventories and boundary fluxes of dissolved organic nitrogen and dissolved iron to the West Florida Shelf (WFS) to assess their role in supporting the oligotrophic WFS ecosystem. To assess the spatial and temporal...
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...
Sea Turtle Nesting Decision Points and Beach Profile Data on Florida Beaches Sea Turtle Nesting Decision Points and Beach Profile Data on Florida Beaches
This dataset, collected and prepared by the U.S. Geological Survey St. Petersburg Coastal and Marine Science Center (USGS - SPCMSC), includes sea turtle nesting decision point locations and cross-shore beach profiles at those locations. The data were collected by a person walking with a survey backpack equipped with a Global Positioning System (GPS) receiver and GPS antenna. The surveys...
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...
Elevation models, aerial imagery, LiDAR point clouds (LPCs), vegetation survey, and GPS data collected during uncrewed aircraft systems (UAS) operations at Lower Darby Creek, Darby Township, Pennsylvania, August 28 to September 1, 2023 (ver. 1.1, July 202 Elevation models, aerial imagery, LiDAR point clouds (LPCs), vegetation survey, and GPS data collected during uncrewed aircraft systems (UAS) operations at Lower Darby Creek, Darby Township, Pennsylvania, August 28 to September 1, 2023 (ver. 1.1, July 202
Two DJI M600 small Uncrewed Aircraft Systems (sUAS) were used to collect aerial remote sensing data over various locations within the Lower Darby Creek Superfund Site and the adjacent John Heinz National Wildlife Refuge (NWR). Datasets included natural (RGB) color images, multispectral images, and LiDAR Point Clouds (LPCs). These data were processed to produce high resolution digital...
Beach foreshore slope for the Gulf Coast of the United States Beach foreshore slope for the Gulf Coast of the United States
This data release contains foreshore slopes for primarily open-ocean sandy beaches along the United States portion of the Gulf of Mexico (Texas through Florida). The slopes were calculated while extracting shoreline position from lidar point cloud data collected between 2001 and 2018. The shoreline positions have been previously published, but the slopes have not. An alongshore reference...
Radiometric Ages and Descriptive Data for Late Holocene Acropora spp. Corals From Dry Tortugas National Park Radiometric Ages and Descriptive Data for Late Holocene Acropora spp. Corals From Dry Tortugas National Park
This data release compiles radiometric data, photographs, and descriptive collection information (location, elevation, etc.) for late Holocene sub-fossil Acropora palmata and A. cervicornis coral samples collected from the coral reefs of Dry Tortugas National Park, Florida (DRTO) from 2015 to 2023. The samples were collected under scientific research permits from the U.S. National Park...
