Description
Summary:cells/ml) during the winter period but rose to between 2. 5 ~ 105 and 8.0X 106cells/ ml, depending on depth, in October, when considerable amounts of detrital material I were present in water column and available for heterotrophic activity. A significant decrease in bacterial numbers occurred in early December to <0.5x lO~cells/ml. but recovered later in December to> 5 x lO~cells/m/: the increase in numbers oc-curred at the same time as a bloom of the alga Phaeocyitis poiichetii. The greatest population of bacteria (> 1 X lo6 cells/m/) was recorded in January, by which time the algal bloom was decreasing. 1.
