Sedimentation: Sediment Distribution and Dynamics of the Sea Floor

Rates of accumulation or erosion, grain size, and to some extent the composition of surficial sediments in Long Island Sound are patchy. The variety of sedimentary environments reflects local and regional differences in geologic and oceanographic bottom processes.
