Reef-census Data from Buck Island Reef National Monument

In July of 2016, Florida Institute of Technology researchers, in collaboration with the U.S. Geological Survey (USGS), conducted reef-census surveys at 54 sites around Buck Island Reef National Monument, St. Croix, U.S. Virgin Islands. The sites are divided across two reef sectors (North and South) and three reef habitats (fore reef, reef crest, and back reef) (Figure 1). These data were used to e

Radioanalytical Measurements on Samples From Submarine, Karstic Carbonate Features Along the West Florida Shelf

Relict karstic features, often referred to as blue holes, are common features along continental shelves that are underlain by carbonate rich sediments and/or rocks. Several of these features occur along the west-Florida shelf within the Gulf of Mexico, including the two mentioned in this data product: Amberjack Hole and Green Banana Sink (hereafter referred to as Green Banana). Scientists from U.S

Coastal Multibeam Bathymetry and Backscatter Data Collected in May 2021 from Seven Mile Island, New Jersey

Scientists from the U.S. Geological Survey St. Petersburg Coastal and Marine Science Center in St. Petersburg, Florida (USGS - SPCSMC), conducted a geophysical survey nearshore Seven Mile Island, New Jersey, during May 2021. During this study, multibeam bathymetry and acoustic backscatter data were collected aboard the R/V Sallenger. Efforts were supported by the National Fish and Wildlife Foundat

Prokaryotic Communities From Marine Biofilms Formed on Stainless Steel Plates in Coral Mesocosms - Raw and Processed Data

The files in this data release are those referenced in the journal article by Evans and others (2022) entitled "Ship Biofilms as Potential Reservoirs of Stony Coral Tissue Loss Disease." They contain an amplicon sequence variant (ASV) table and the raw 16S ribosomal ribonucleic acid (rRNA) gene amplicon deoxyribonucleic acid (DNA) sequence files from 15 microbial communities (sample names: CnD16B,

Archive of Chirp Subbottom Profile Data Collected in 2015 From Dauphin Island, Alabama

As part of the Alabama Barrier Island Restoration Feasibility Study, scientists from the U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center (SPCMSC) conducted a nearshore geophysical survey to map the shoreface and determine Holocene stratigraphy near Dauphin Island, Alabama (AL) in September of 2015. The objective of the project is to investigate nearshore geologic con

Coastal Bathymetry and Backscatter Data Collected in June 2021 from Rockaway Peninsula, New York

Scientists from the U.S. Geological Survey St. Petersburg Coastal and Marine Science Center in St. Petersburg, Florida (USGS-SPCSMC), conducted a geophysical survey nearshore the Rockaway Peninsula, New York, during June 2021. During this study, multibeam bathymetry and acoustic backscatter data were collected aboard the R/V Sallenger. Efforts were supported by the National Fish and Wildlife Found

Mangrove Peat Radiocarbon Ages From Snipe and Swan Key, FL

In 2016, researchers collected cores of mangrove peat from two islands in the Florida Keys: Snipe Key (24.679°N, 81.653°W) and Swan Key (25.349N, 80.251W) (Fig. 1). This data release contains the radiocarbon ages and associated data for peat samples analyzed throughout the two cores. These data were used by Khan and others (in preparation) to reconstruct the millennial-scal

Grain-Size Data From Sediment Samples at Seven Mile Island, New Jersey and Rockaway Peninsula, New York

Sediment grab samples were collected from one onshore location and 32 undisturbed locations along the seafloor around Seven Mile Island, New Jersey (NJ) and Rockaway Peninsula, New York (NY). The sediment grab samples were collected in May and June of 2021 at locations within the area where multibeam bathymetry surveys were also conducted during the same trip. All sediment samples were analyzed us

Radiochemical Data From Sediment Cores Collected on Deer Island, Mississippi

In December 2021, four sediment push cores (core names appended with 'M' for marsh push core) and peat augers (core names appended with 'R' for Russian peat auger) were collected from the marshes of Deer Island, Mississippi during U.S. Geological Survey (USGS) field activity number (FAN) 2021-351-FA. Select intervals from the manual push cores were analyzed for determination of lead-210 activities

National Assessment of Hurricane-Induced Coastal Erosion Hazards: Puerto Rico

These datasets contain information on the probabilities of hurricane-induced erosion (collision, inundation, and overwash) for each 100-meter (m) section of the Puerto Rico open-ocean coastline for category 1-5 hurricanes. The analysis is based on a storm-impact scaling model (Sallenger, 2000; https://www.jstor.org/stable/4300099) that uses observations of beach morphology combined with sophistica

Atlantic and Gulf Coast Sandy Coastline Topo-Bathy Profile and Characteristic Database

Seamless topographic-bathymetric (topo-bathy) profiles and their derived morphologic characteristics were developed for sandy coastlines along the Atlantic and Gulf coasts of the United States. The topo-bathy profiles are published as a database in the Hierarchical Data Format version 5 (HDF5) which contain cross-shore distance coordinates, Universe Transverse Mercator (UTM) coordinate system East

Assessing the Northeastern Gulf of Mexico Microtidal Wetland System Change in the Apalachicola-Big-Bend Region Under Sea-Level-Rise: Model Inputs and Outputs

Using the Hydrodynamic-Marsh Equilibrium Model (Hydro-MEM), the wetlands system within the Apalachicola-Big-Bend region of Florida (FL) (Fig. 1) was assessed using three sea-level rise scenarios of intermediate-low (50 centimeters [cm] by 2100), intermediate (1 meter [m] by 2100), and intermediate-high (1.5 m by 2100) from the National Oceanic and Atmospheric Administration (NOAA).
