A PLANKTON SURVEY OF THE CHESAPEAKE BAY USING A CONTINUOUS UNDERWAY SAMPLING SYSTEM.

Abstract

A survey of the net plankton of the Chesapeake Bay was undertaken using a continuous underway sampling system. A total of nine cruises was made between October 1955 and October 1956. The survey included the entire length of the Bay. Sixty-three diatoms, 19 dinoflagellates and 10 green algae were identified and quantitative distributions were noted. Two general distribution patterns of the phytoplankton were noted: (a) those which exhibited a single maximum and (b) those which exhibited two maxima. Temperature and salinity were the only environmental factors measured. In a few cases there are suggestions of weak correlations between these factors and phytoplankton distributions, but these were obviously not the primary factors controlling the distributions. Nutrients, radiant energy and grazing factors were not evaluated. Zooplankton were not emphasized in this survey and were identified and counted only to general taxa. These results indicate the need for additional research on the plankton of the Chesapeake Bay. (Author)
