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...

To better understand sediment deposition in marsh environments, scientists from the U.S. Geological Survey, St. Petersburg Coastal and Marine Science Center (USGS-SPCMSC) selected five marsh study sites (Sites 5, 6, 7, 8, and 9) and four nearshore estuarine study sites (Sites 8S, 8D, 9S, 9D) along the Point Aux Chenes Bay shoreline of the Grand Bay National Estuarine Research Reserve...

This data release contains new, 40–70-year long sub-annual strontium-to-calcium ratio (Sr/Ca) records and linear extension measurements from five mid-to-late Holocene, Orbicella faveolata corals from the Dry Tortugas National Park (DT) and Marquesas Keys (MK), Florida (FL). U.S. Geological Survey (USGS) researchers used these Sr/Ca data to calculate sea-surface temperature (SST) using...

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...

This data release compiles radiometric data, photographs, and descriptive collection information (location, elevation, etc.) for late Holocene sub-fossil Acropora palmata and A. cervicornis coral samples collected from the coral reefs of Dry Tortugas National Park, Florida (DRTO) from 2015 to 2023. The samples were collected under scientific research permits from the U.S. National Park...

In April 2023, scientists from the U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center (SPCMSC) collected 11 sediment vibracores within East Bay, St. Andrew Bay, Florida (FL). Sediment vibracore and lithology data in this data release provide assessments on the composition and age of sediments below the seafloor. This data release serves as an archive of...

Coastal marshes across the Northern Gulf of Mexico are critical ecosystems, providing wildlife habitat, nursery for many species of fish, a carbon sink, and protection of communities from storm surge, but are vulnerable to coastal hazards, such as wave attack, sea level rise, and subsidence. While many marshes accrete vertically to compensate for rising sea level, marsh loss can occur...

In 2015, scientists from the U.S. Geological Survey St. Petersburg Coastal and Marine Science Center (USGS SPCMSC) conducted sediment sampling surveys on and around the barrier islands of Dauphin Island and Little Dauphin Island, Mobile County, Alabama (AL). The study investigated the surficial sediment surrounding Dauphin Island and surrounding environments to inform sediment transport...

The sensitivity to sediment parameterization and initial bed configuration on sediment transport processes and morphological evolution are assessed through process-based numerical modeling. Six sensitivity cases using a previously validated model for Dauphin Island, (Alabama) were modeled using Delft3D (developed by Deltares) to understand impacts on bed level morphology, barrier island...

As an effort to improve the accessibility of U.S. Geological Survey (USGS) resources to communities in Puerto Rico, a research team held a virtual internal meeting amongst USGS colleagues (organized with a professional facilitator) to identify and gather information on existing USGS natural hazards data, knowledge, and tools available for Puerto Rico. As a result, a bilingual website...

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 data were collected aboard the research vessel (R...

These datasets comprise of laboratory observations of oscillatory flows over mobile sand ripples. The data were collected in the Small-Oscillatory Flow Tunnel (S-OFT) in the Sediment Dynamics Laboratory at the U.S. Naval Research Laboratory, Stennis Space Center, Mississippi (MS), while Donya Frank-Gilchrist was a National Research Council post-doctoral fellow there. The flow tunnel has...
