Samples were collected from depths between the surface and 80m. Numbers were low (mean: ca. 1.1×10^5 cells/ml) during the winter period but rose to between 2.5×10^5 and 8.0×10^5 cells/ml, depending on depth, in October, when considerable amounts of detrital material were present in water column and available for heterotrophic activity. A significant decrease in bacterial numbers occurred in early December to <0.5×10^5 cells/ml, but recovered later in December to >5×10^5 cells/ml; the increase in numbers occurred at the same time as a bloom of the alga Phaeocystis pouchetii. The greatest population of bacteria (>1×10^6 cells/ml) was recorded in January, by which time the algal bloom was decreasing.}, pages = {16--22}, title = {SEASONAL FLUCTUATION OF BACTERIAL NUMBERS NEAR THE ANTARCTIC CONTINENT (Eleventh Symposium on Polar Biology)}, volume = {3}, year = {1990} }
