Data

These geospatial datasets describe positions, elevations, and uncertainties for synthetic elevation checkpoints generated across the developed coastline of North Carolina. Two datasets are provided as point shapefiles and American Standard Code for Information Interchange (ASCII) tables, and each contains synthetic checkpoints generated using a time series (1996-2018) of digital...

This pilot study was intended to test whether Globorotalia truncatulinoides (G. truncatulinoides) and Globorotalia menardii (G. menardii) specimens could be successfully harvested from offshore plankton tow samples and kept alive in a laboratory at the U.S Geological Survey St. Petersburg Coastal and Marine Science Center (USGS SPCMSC). The methodologies and resources which were used to...

This data release contains two sets (reflective and dissipative) of synthesized barred beach profiles based on conditions in the University of New South Wales Water Research Laboratory's 0.9-meter wave flume. The profiles were collected using the methods outlined in Conti and others (2024) and then synthesized using the functions and relationships described by Stephens and others (2010)...

Two digital video cameras were installed at Dorado, Puerto Rico (PR); camera 1 faced west alongshore and camera 2 faced northeast alongshore. Every hour during daylight hours, daily starting in August 2022, the cameras collected raw video and produced snapshots and time-averaged image products. This data release includes the necessary intrinsic orientation (IO) and extrinsic orientation...

The impacts of five proposed restoration alternatives at Little Dauphin Island, Alabama (AL) were assessed using process-based numerical models to simulate annual scale sediment transport and storm-driven morphological change. The five restoration alternatives include a no-action scenario representing a continuous island (R0), a tidal inlet channel realignment (R1), a sand spit (sand...

As part of the restoration monitoring component of the Deepwater Horizon early restoration project, scientists from the U.S. Geological Survey St. Petersburg Coastal and Marine Science Center in St. Petersburg, Florida (USGS–SPCSMC), conducted a bathymetric survey near Breton Island, Louisiana (LA). During this study, multibeam bathymetry and acoustic backscatter data were collected...

This dataset contains hourly moisture content, salinity, and temperature measurements for sediment within a dune profile at Madeira Beach, Florida, USA. The data was collected between January 25, 2023, and August 31, 2023, following impacts from Hurricane Idalia. Data were collected using 5 moisture probes that extended 90 centimeters (cm) below the surface, with sensors spaced 10 cm...

Scientists from the U.S. Geological Survey St. Petersburg Coastal and Marine Science Center in St. Petersburg, Florida (USGS–SPCSMC), conducted a geophysical survey of the northern Chandeleur Islands, Louisiana during two survey legs: June 12-21 and July 31-August 11, 2023. During this study, multibeam bathymetry and sub-bottom geophysical data (Forde and others, 2024) were collected...

Scientists from the U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center (SPCMSC) conducted single-beam and multibeam bathymetry (Stalk and others, 2025) surveys around the northern Chandeleur Islands, Louisiana, from June 12 to 20 and from July 31 to August 9, 2023, as part of Field Activity Number (FAN) 2023-325-FA. The purpose of data collection was to...

Two digital video cameras were installed at Isla Verde, Puerto Rico (PR); camera 1 faced northeast offshore and camera 2 faced east-northeast along the beach. Every hour during daylight hours, daily starting in August 2022, the cameras collected raw video and produced snapshots and time-averaged image products. This data release includes the necessary intrinsic orientation (IO) and...

The U.S. Geological Survey (USGS) deployed thirteen pressure loggers (RBR) to measure water levels and wave conditions on a reef-lined coast in Dorado, Puerto Rico. These loggers were positioned along a cross-shore transect that extends 1.8 kilometers from the coast (on the forereef, reef crest, and reef flat) and at various points within the reef embayment. Initial deployments began in...

As part of the Interconnected Coastal Environments at Decadal Timescales and Coastal Sediment Availability and Flux projects, scientists from the U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center conducted a nearshore geophysical survey to map the shoreface and characterize stratigraphy near Wallops and Assawoman Islands, Virginia (VA). The purpose of this...
