In 2021 and 2022, scientists from the U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center (SPCMSC) and the USGS New York Water Science Center (NYWSC), on behalf of SPCMSC, conducted sediment sampling and ground penetrating radar (GPR) surveys at Point O' Woods and Ho-Hum Beach (NYWSC, 2021) and Watch Hill, Long Cove, and Smith Point (SPCMSC, 2022), Fire Island...
Radiochemical Data From Sediment Cores Collected on Deer Island, Mississippi 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...
Archive of Chirp Subbottom Profile and Single-Beam Bathymetry Data Collected in 2021 From Santa Rosa Island, Florida Archive of Chirp Subbottom Profile and Single-Beam Bathymetry Data Collected in 2021 From Santa Rosa Island, Florida
As part of the Coastal Resource Evaluation for Management Applications (CREMA) Project, 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 Pensacola Beach, Florida (FL) in June of 2021. The objective of the project is to...
Archive of Chirp Subbottom Profile Data Collected in 2019 From Rockaway Peninsula, New York Archive of Chirp Subbottom Profile Data Collected in 2019 From Rockaway Peninsula, New York
As part of the Coastal Sediment Availability and Flux Project, scientists from the U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center conducted a nearshore geophysical survey to map the shoreface of Rockaway, New York (NY) between September and October of 2019. The objective of the project is to improve the understanding of barrier island geomorphic evolution...
Coastal Bathymetry and Backscatter Data Collected in September-October 2019 from Rockaway Peninsula, New York Coastal Bathymetry and Backscatter Data Collected in September-October 2019 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 September and October 2019.
