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 using a laser diffraction Coulter LS13 320 particle-size analyzer to measure the grain size distribution of the sediments. All the samples within the dataset are referred to by field activity numbers (FANs) 2021-318-FA and 2021-319-FA and are part of the Coastal Sediment Availability and Flux (CSAF) research project which collects geophysical, remote sensing and sediment data to inform models for improving prediction of coastal systems' response to extreme weather and sea-level rise.
