Bottom sediments on the Continental Shelf of the northeastern United States Cape Ann, Massachusetts, to Casco Bay, Maine

This set of maps covers part of the continental shelf from about 15 km north of Cape Ann, Massachusetts to Casco Bay, Maine (42-50' to 43-50' North latitude, west of 70°-00' West longitude). It extends data presented in a companion study that covered the contiguous area to the south as far as Cape Cod, Massachusetts (Schlee and others, in press). The maps in both studies are intended to serve as guides to the surficial sediment distribution. Because sediment texture is in part a reflection of long-term hydrologic conditions the maps will also help to infer the important sediment transport mechanisms in the area and thus will be useful in problems relating to disposal of solid and liquid waste offshore (Schlee and others, in press).
