Seven samples were collected from the surface marine deposits at 7 to 38m in water depth in the Great wall Bay, King George Island by the First China National Antarctic Research Expedition.A total of 36 foraminiferal species from the deposits were identified, of which 20 species are living ones.All belong to species common in polar region or in cold water seas.Existence and distribution of living foraminifera in surface depoits have been determined by staining of Rose Bengal.Moreover, comparison between living and dead foraminiferal assemblages shows that dominant species, diversity and ratio of the three suborders at station No.9 are similar, although there is a little difference, i.e.the abundance of each species in dead assemblage differs from that in living one, and rare species in dead assemblage are more than in living one. The results discussed above show that some good environmental information is preserved in foraminiferal assemblages, the transportation at station No.9 is not a major problem and, therefore, in this case we shall regard the present foraminiferal assemblages as a basis for the palaeoecological interpretation.Quantitative analyses of foraminfera are given in this paper.According to their distribution in the Great Wall Bay, two foraminiferal assemblages can be distinguished as follows. (1)The assemblage mainly consisting of Bolivina Pseu-dopunctata, which is distributed over the mouth of the Great Wall Bay, (2) The assemblage mainly consisting of Trochammina malovensis, which is distributed within the nearshore area of the Bay.
