Abstract
The Tsushima Warm Current plays a role of transporting not only water mass but also materials including nutrients to the East Sea through the Korea Strait. This study aims to examine an effect of the nutrient transport through the Korea Strait on the East Sea ecosystem. For this study, we used a four-component low trophic biological model coupled with a physical model due to lack of in-situ observational data. Numerical experiments were conducted with three different open boundary conditions of nutrient flux through the Korea Strait: zero, a constant, and a seasonally varying value. When zero nutrient flux was given, both spring and fall blooms were not evident in most of southern basin. With the constant and the seasonally varying nutrient fluxes, the simulated chlorophyll-a showed the observed temporal and spatial distributions. Interestingly, the results from these two boundary conditions seemed to be similar to each other indicating that the distributions of chlorophyll-a are less sensitive to the variation of nutrient flux if the flux is non-zero. These results suggest that the nutrient flux through the Korea Strait may contribute to the primary productivity in the southern East Sea.ait on the East Sea ecosystem.
