Data

The U.S. Geological Survey (USGS) conducted interviews of professionals who make decisions about marshes during the Salt Marsh Evolution along the South Atlantic Bight project (SAB project) and the Marsh Model Retrospective initiative. During the SAB project, an advisory committee of marsh model users were interviewed in June 2023 about what decisions they make about marshes and how they...

Small Uncrewed Aircraft Systems (sUAS) were used to collect aerial remote sensing data over Sesuit Marsh in Dennis, MA. Raw data from aerial surveys include aerial images from natural color (RGB) and multispectral cameras and raw lidar data. These datasets were processed to produce high resolution digital elevation models (DEM), image mosaics, and lidar point clouds (LPC) to provide...

The data in this release support the journal article "Outwash events inhibit vegetation recovery and prolong coastal vulnerability". The research details the vegetation cover in washover and washout locations in North Carolina, Texas, and New York after hurricanes Florence, Dorian, Harvey, Ike, and Sandy. Aerial imagery observations indicate that washout sites create ponds and have a...

This data release contains the estimated lifespans of salt marshes in E.B. Forsythe National Wildlife Refuge (EBFNWR) and Atlantic-facing New Jersey. The lifespans are calculated based on estimated sediment supply and sea-level rise (SLR) predictions, following the methodology of Ganju and others (2020). The salt marsh delineations are from Ackerman and others (2024) and Defne and Ganju...

Two digital video cameras (CACO-02) were installed at Marconi Beach, Cape Cod National Seashore in Massachusetts (MA) as part of a U.S. Geological Survey (USGS) research project to study the beach and nearshore environment. The cameras faced north-east (c1) and east (c2) along the beach and every half hour during daylight hours. They ran daily from March through June 2021, Feburary...

A digital video camera was installed at Marconi Beach, Cape Cod National Seashore in Massachusetts (MA) as part of a U.S. Geological Survey (USGS) research project to study the beach and nearshore environment. The camera faced north-east along the beach and every hour during daylight hours, daily from January 2024 to September 2024, the camera collected raw video and produced snapshots...

Ground reference data in the form of ecogeomorphic evaluations, topographic survey measurements, and geotagged photographs were collected at four areas of interest (AOI) across Fire Island National Seashore (FIIS), NY, USA September 16-19, 2024, that document site conditions. The overall goals of USGS personnel for the data collection were to: (1) collect ground reference data that...

A coupled hydrodynamic and sediment transport model was developed to simulate the dispersal of fine-grained sediment from beach nourishment projects near Santa Barbara, California. The model simulations were used to quantify the size and extent of sediment plumes resulting from nourishment projects and evaluate the potential impacts of beneficial use of fluvial sediment captured in...

This shapefile contains habitat polygons identifying the dominant and major geomorphological structure, biological type and percent cover, and geologic zone for 11 square kilometers of Olowalu reef off west-central Maui at a minimum mapping unit of 100 square meters. Habitats were mapped with heads-up digitization using the NOAA Habitat Digitizer Extension in ArcMap (Esri, v.10.8.2)...

The U.S. Geological Survey St. Petersburg Coastal and Marine Science Center’s (USGS SPCMSC) Core Archive in St. Petersburg, FL contains a collection of coral-reef cores collected from throughout the Florida Keys reef tract (FKRT; Fig. 1). In a previous study (Toth and Stathakopoulos, 2019), USGS researchers analyzed the upper, Holocene (~11,700 years ago to present) sections of those...

As part of the Breton Island Post Construction Monitoring project, scientists from the U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center conducted a nearshore geophysical survey in August 2024 to map the borrow site created during the Breton Island, Louisiana (LA) restoration effort that began in December 2020. The restoration effort was part of the Deepwater...

The U.S. Geological Survey (USGS) deployed a series of oceanographic instruments at Madeira Beach, Florida configured to measure water levels, temperature, waves, and three-dimensional flow velocities throughout the water column. The instruments include (1) Spotter wave buoys with Smart Mooring (2) RBR pressure loggers, and (3) RDI Sentinel-V Acoustic Doppler Current Profilers (ADCP)...
