    dct:description "Boston Harbor (and its approaches) is a glacially carved, tidally dominated estuary in western Massachusetts Bay.  Characterized by low river discharge and significant human impact, the harbor is typical of many bays and estuaries along the New England coast.  The sands and gravels that floor Massachusetts Bay and the Harbor approaches are relict glacial sediments. However, fine-grained sediments are accumulating in areas of lower energy." ;
