Abstract : Methods were evaluated for measuring the bottom-sediment distribution in harbors. The most widely distributed sediment was gravel which was most extensive to the east and northeast of North Channel; the gravel reached sizes of 60 cm. Silty sand and sandy silt were the next most frequent sediments and were confined to the northwestern border and to the deeper water at the extreme eastern edge of the area. Shells were a minor constituent and predominated in a few patches south of Marblehead. The gravels represent a past period of deposition; sand, silt and clay are presently being deposited at a rate not exceeding 0.5 in./yr. Deposition will not affect military operations.
