Data

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...

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...

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)...

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...

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...

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...

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...
