Shoreface Geology, Morphology, and Volume at Seven Mile Island, NJ

As part of the National Fish and Wildlife Foundation (NFWF)-funded Monitoring Hurricane Sandy Beach and Marsh Resilience in New York and New Jersey project (NFWF project ID 2300.16.055110), the U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center (SPCMSC) is using boat-based bathymetry and geophysics data to monitor the post-restoration evolution of shorefaces at two post-Hurricane Sandy beach and marsh restoration sites in New York and New Jersey. These data and derived ecological resilience metrics will be used to assess the cost-effectiveness and ecological benefits of the restoration techniques and evaluate how the restored parts of the coast have changed through time. Geophysics-derived beach morphologic features, including the sand volume of the shoreface, help define coastal vulnerability to storm impacts and long-term shoreline change. Additional resources include published multibeam and single-beam bathymetry collected in 2018 (Farmer and others, 2019; https://doi.org/10.5066/P9BSJHVL), 2021 (Stalk and others, 2022; https://doi.org/10.5066/P9M2EQIR), 2022 (Lyons and others, 2023; https://doi.org/10.5066/P9P07T3W), and 2023 (Stalk and others, 2024; https://doi.org/10.5066/P13TUAJH); chirp seismic reflection data collected in 2022 (Forde and others, 2023; https://doi.org/10.5066/P9PY4RR0); and sediment grain-size data from samples collected in 2021 (Everhart and others, 2022). This dataset includes the Seven Mile Island shoreface and encompasses NFWF restoration project 41991 (Increasing Seven Mile Island’s beach resiliency, New Jersey).
