The concentrations and distributions of four species of inorganic nutrient salts in surface sea water of Chinese Great Wall Bay and its adjacent sea area, Antarctica were surveyed during austral summers of 1993～1994.The results obtained are as follows:The general concentrations of NH4-N, NO3-N, NO2-N and PO4-P are 2. 13, 7. 07, 0. 74 and 1. 12 μg. din-3, respectively. Generally speaking, the concentrations are higher inside the Bay than those　 outside and the higher values of those inorganic salts often appear in December. The time for the station　where their higher and lower concentrations appear are not completely the same. The descending order　of the magnitudes of ΣN/P value according to the arrangement monthly is: Dec. Feb. Jan.. The　 variations of water temperature are mostly consist with the concentrations of NH4-N, PO4-P and ΣN/P, but not often with NO2-N. The low concentrations of nutrient salts as shown in some stations may be related with absorption by phytoplankton, perhaps including autotrophic bacteria.The results suggest that the area surveyed has a typical characteristic of an inner shallow water bay, sub-Antarctica. The nutrients needed for phytoplankton are sufficient, and the Bay surveyed is still in a normal condition.
