Relative amounts of phytoplankton, bacteria and microzooplankton are determined in the composition of the suspended matter of the south Atlantic anticyclonic circulation waters (February-March, 1973). Water sampling for suspended matter and determination of the organism biomass was performed from one and the same bathometer. Comparison was made relative to dry material. The total biomass of organisms in suspension composition varied from 23.9 to 0.7%, reaching the maximum values in the littoral upwelling zone and gradually decreasing towards the central regions of the ocean and with depth. |
