The primary productivity and physicochemical factors were surveyed seasonally in Gangjin bay from February to October in 1998. The determination of the Primary Productivity Was performed in Situ by isotope-method using NaH/sup 14/CO/sub 3/. The range of primary productivity was 2.78 mgC m/sup -3/ hr/sup -1/-4.92 mgC m/sup -3/ hr/sup -1/ according to seasons. The primary productivity showed the highest value in summer, followed by those of winter, autumn and spring. The primary productivities of station 1, 2 which are located the upper area, were lower than those of station 3, 4, 5 and 6. The correlations showed that the primary productivity correlated with chlorophyll a, underwater light intensity but reversely correlated with suspended solids. These results suggested that the primary productivity in Gangjin Bay was mainly influenced by the inflow of freshwater from Tamjin River.
