다국어 초록 (Multilingual Abstract)

Abiotic environmental factors and primary production were investigated at the adjacent waters of Kori in southeastern coast of Korea, seasonally in 1992. The average concentrations of chlorophyll-a varied from 2.01 to 5.88㎍Chl-a·ℓ^-1 and showed spring and autumn bloom. The fraction of nano- and picoplankton was 74.8% of total biomass of primary producers in April but larger cell size group, netplankton contributed 54.9% to the total biomass and caused autumn bloom in October. Daily primary productivity ranged from 316.5 to 3538.8㎎C·m^-2·day^-1. Except the result of October, the production of nano- and picoplankton were over than 70% of primary production. Assimilation number of phytoplankton ranged from 0.20 to 5.79㎎C·㎎ Chl-a^-1·hour^-1 and the average N/P ratio was 8.65. Nitrogenous nutrient might be limiting factor to the growth of primary producers because of low level of N/P ratio. The data of apparent oxygen utilization (AOU) showed vertical stratification of water column in summer.
