Abstract

Abstract

The cell abundance,the composition of dominant species,size fractionated biomass and productivity of phytoplankton,new production,the environmentally rest ricted mechanism are studied in the Prydz Bay and the adjacent Indian sector of the Southern Ocean during the austral summer of 1998/1999.The results show that there is marked feature of spatial zonation in the sea areas investig ated.In the Prydz Bay and its adjacent continental shelf,the biomass and productivity of phytoplankton are high;those of continental slope and open ocean area are obviously low.The nut rient concent ration has opposite distribution trend,due to the consumption of phytoplankton.It is mainly affected by the vertical stability of water column,grazing pressure of zooplankton,temperature and light,etc.The results of size-fractionation show that the average contribution of netplankton to total chlorophyll a in the studiy sea areas is 52.2%,those of nano-and picoplankton are 29.4% and 18.4%,respectively.The average contribution of netplankton to total primary production is 52.4%,those of nano-and picoplankton are 28.7% and 18.9%,separately.It is the same as previous conclusion that the contribution of picoplankton to productivity is slightly larger than that to biomass of phytoplankton communities.The average new production and f-ratio are 230.6 mg/(m²·d) and 0.43,respectively.
