Cape Cod Bay is described elsewhere (Young and Rhoads, 1971). It encompasses 1600 km2, is circular, and opens northward to Massachusetts Bay (Figure 1). Mean tidal range at Plymouth, Massachusetts is m. Average annual extremes of surface temperature (— and °C) and salinity ( and ) are similar to bottom temperature ( and °C) and bottom salinity ( and ). Bottom temperatures ranged from to °C. Highest and lowest values of both hy- drographic features are normally associated with surface waters. A summer ther- mocline appears in April and disappears in October. Reverse thermoclines may occur at 15 to 25 m during mid-winter when bottom water may be 1 to °C warmer than surface water. Sediments consist of a mixture of clayey-silt, silt, sand, and gravel. Sand and silt each comprise approximately 40-45% of the bay sediments, and gravel comprises the smallest component of sediment (Young and Rhoads, 1971). MATERIALS AND METHODS The methods used to collect and process the samples are described in detail by Young el al. (1971). Since the goals of the study were to maximize the number of.
