Data

In 2023, scientists from the U.S. Geological Survey St. Petersburg Coastal and Marine Science Center (USGS SPCMSC) conducted a sediment sampling survey at the northern Chandeleur Islands, Louisiana. Funded by the Extending Government Funding and Delivering Emergency Assistance Act (Public Law 117-43) enacted on September 30, 2021, these data complement sediment data from samples...

During the summers of 2022 and 2023, U.S. Geological Survey (USGS) researchers conducted underwater surveys aimed at quantifying the impact that past coral restoration by Mote Marine Laboratory had on the reef-accretion process. The surveys were conducted along paired transects representing restored and non-restored areas of eight offshore reefs and three patch-reef sites in the Lower...

During the summers of 2022 and 2023, U.S. Geological Survey (USGS) researchers conducted underwater photographic surveys aimed at quantifying the impact that past coral restoration by Mote Marine Laboratory had on the reef-accretion process. A total of 39,840 non-georeferenced diver-based images were collected. The surveys were conducted along paired transects (approximately 10x2 meter...

This data release contains model inputs and outputs of water level elevations resulting from deterministic simulations along the South Atlantic Bight (SAB), which extends roughly from Cape Hatteras, North Carolina to the Upper Florida Keys, Florida, USA. For further information regarding model input generation and visualization of model output topography and bathymetry, refer to Woodruff...

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 Wallops and Assawoman Islands, Virginia (VA). During this study, multibeam bathymetry data were collected aboard the Research Vessel (R/V) Sallenger from June 1-13, 2024, as a part of field activity number (FAN) 2024-310...

The U.S. Geological Survey St. Petersburg Coastal and Marine Science Center (USGS SPCMSC) collected single beam echosounder (SBES) and differential global positioning system (DGPS) elevation data in the nearshore and beach environments of Wallops and Assawoman Islands, Virginia, in June 2024. This data release includes the processed SBES and DGPS elevation point data (xyz) for Field...

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...
