Sediment Data From Vibracores and Sand Augers Collected in 2021 and 2022 From Fire Island, New York

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, New York. These data complement previous SPCMSC GPR and sediment sampling surveys conducted at Fire Island in 2016. This data release serves as an archive of vibracore and sand-auger sediment cores collected from back-barrier environments on Fire Island from March 29-April 3, 2021 and April 19-22, 2022 (USGS Field Activity Number 2021-312-FA). GPR data collected during the same survey are available as a separate data release (Forde and others, 2022). Sedimentologic data from these cores, including descriptive core logs, grain-size data, and the results of radiocarbon (14C) analyses, are provided to characterize and date shallow subsurface stratigraphic units such beach, dune, or washover deposits and support analyses presented by Ciarletta and others (2022). Data acquisition and processing methods are modified from USGS Data Series 1037 and 1100.
