Abstracts

The phytoplankton dynamics considering size structures were investigated in Asan Bay. The contribution of netphytoplankton (>20μm) was high in spring, whereas contributions of nanoplankton (2<20μm) increased from summer to winter. The enrichment of PO4 3- in winter and the increase of radiance in spring often appeared to control phytoplankton community structure in spring. Water runoff might bring NO2 +NO3 and NH4 + into Asan Bay in summer. However, phytoplankton biomass didn't increase in summer season. Based on these results, the variations of phytoplankton size structures might be determined by different light and nutrient availability. Application of dynamical estuarine ecosystem modeling for phytoplankton size structure using STELLA with state variables of the model included major inorganic nutrients(NO2 + NO3, NH4+, PO4 3, Si), size classes of phytoplankton (netphytoplankton, nanophytoplankton, two classes of zooplankton (mesozooplankton, microzooplankton), and organic matters (POC, DOC). The results suggest that understanding of phytoplankton size structure is necessary to investigate phytoplankton dynamics and to better manage water quality in Asan Bay.
