Possible Interchange of Sediments Between a Beach and Offlying Linear Shoal
An investigation of Gilbert Shoal, a typical nearshore linear shoal on the Florida Atlantic coast, was undertaken to determine if significant interchange of sediments occur between the shoal, the surrounding seafloor, and the adjacent beach. The principal study technique made use of selected sedimen...
