Geologic Investigations Series Map I-2732-A
By Bradford Butman, Laura Hayes, William W. Danforth, and Page C. Valentine
This 40 x 32 inch map shows sea floor depth as topographic contours at a scale of 1:25,000. It is based on multibeam echo-sounder data collected during four cruises conducted between the fall of 1994 and the fall of 1998. The map is part of a 3-quadrangle map series showing the area offshore of Boston, Mass., that is companion to the Stellwagen Bank National Marine Sanctuary map series (Valentine and others, 2001, 2003a-c; also see location map). Other maps of Quadrangle 2 depict shaded relief and topographic contours (Butman and others, 2003a), and backscatter intensity, shaded relief, and topographic contours (Butman and others, 2003b).
