Cape Cod Bay, lying on the Massachusetts coast partly enclosed by Cape Cod, is in a glaciated region of low relief. Coarse sediments generally occur in areas exposed to wave and current action as in shallow water near shore or on shoals, and in the deep channel north of the tip of Cape Cod, which is swept by tidal currents. Fine sediments are restricted to the deeper water in the central portion of the Bay, and to the small well-protected embayments of the shore. Although Hough (1942) is available as part of the NGDC Deck 41 Database, additional data from the original report were manually entered and, therefore, this file is unque.
