Scientists from the U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center (SPCMSC) led six coastal sampling events between November 2022 and March 2024 in support of a collaborative research project investigating coastal boundary fluxes of dissolved analyte loads to the West Florida Shelf (National Science Foundation Grant Award OCE-2148989, Project 880516)...

This data release serves as an archive of sediment grain-size data from vibracores collected in October 2023 at Hewes Point in the northern Chandeleur Islands, Louisiana. The vibracores were collected and processed by Coastal Engineering Consultants, Inc. (CEC), Athena Technologies, Inc., and GeoEngineers, Inc. on behalf of the Louisiana Coastal Protection and Restoration Authority (CPRA...

In February 2022, the U.S. Geological Survey St. Petersburg Coastal and Marine Science Center (USGS SPCMSC) conducted multibeam and single-beam bathymetric surveys of the nearshore waters off Madeira Beach, Florida. These data were collected as part of a regional study designed to better understand coastal processes on barrier islands and sandy beaches. Results from this study will be...

This data release contains model inputs and outputs for simulations of hydrodynamic conditions at Panama City, Florida (FL), for Hurricane Sally in September 2020 with the Deltares® XBeach numerical model using methods described in Roelvink and others (2009). The simulations were performed in collaboration with investigators at the U.S. Naval Research Laboratory (NRL) who deployed...

Sediment trap time series studies collect data on planktic foraminiferal flux, assemblage composition, and geochemical responses to environmental variables, which are used in paleoceanographic research. This data release presents weekly-to-monthly resolution foraminiferal assemblage data from a long-running sediment trap study (2008–2020) in the northern Gulf of America (nGulf; 27.5° N...

In July 2025, scientists from the U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center (SPCMSC) collected single-beam bathymetry (SBES) data and sediment vibracores at Lake Maggiore, St. Petersburg, Florida. These data were collected during USGS field activity number (FAN) 2025-309-FA. The SBES data were collected using USGS research vessel (R/V) MAKO. The...

To better understand storm-driven habitat creation and loss, piping plover (Charadrius melodus[BW2.1]) habitat availability was mapped along the Cape Lookout National Seashore, North Carolina (abbreviated in this release as CaLo) for multiple years (2014–2022). To derive the habitat suitability maps, machine learning image classification and other remote sensing tools were used, along...

These geospatial datasets correspond to the extraction of elements and their attributes related to the shoreline and back beach of eleven (11) municipalities in the northwest and north coasts of Puerto Rico (Rincón, Aguadilla, Isabela, Hatillo, Arecibo, Dorado, Vega Baja, Carolina, Loíza, Río Grande, and Luquillo). These data were generated as part of the USGS Development of Coastal...

To assess the spatial and temporal hydrographic variability along the West Florida Shelf (including Tampa Bay and Charlotte Harbor), stable oxygen (d18O) and hydrogen (dD) isotope ratios were measured using water samples collected from across the region by the U.S. Geological Survey (USGS) and collaborators. Surface, bottom, and groundwater samples from a marine well network along the...

The U.S. Geological Survey (USGS) Coastal and Marine Hazards and Resources Program has actively collected geophysical and sedimentological data in the northern Gulf of America (Gulf of Mexico) for several decades, including shallow subsurface data in the form of high-resolution seismic reflection profiles (HRSP). Prior to the mid-1990s, most HRSP data were collected in analog format as...

In June 2025, scientists from the U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center (SPCMSC) conducted sediment core sampling at Midnight Pass, an inlet between Siesta Key and Casey Key, Florida. This inlet was closed by mechanical action in 1983 and reopened by the passage of hurricanes Helene and Milton in 2024, reconnecting Little Sarasota Bay to the Gulf...
