Plum Island Seafloor

This photograph is of the seafloor off the Plum Island coast and shows spider crabs on seabed characterized by coarse sand, gravelly sediment and shell fragments. This photograph was collected as part of a collaborative seafloor mapping program between the USGS and the Connecticut Department of Environmental Protection and the National Oceanic and Atmospheric Administration (NOAA) to interpret surficial sea-floor geology in the Long Island Sound to make informed coastal management decisions.
