Abstract
The nutrients supplied through the Korea Strait (KS) have been believed to have negligible effects on the nutrient budget and biological productivity of the southern East Sea (Japan Sea). However, recent studies based on observations suggest that large amounts of dissolved inorganic nitrogen and phosphorus, comparable to the levels in the Changjiang water and the Taiwan Strait, are transported through the eastern channel of the KS, with considerable interannual variation. This study aims to examine the effects of nutrient transport through the KS on the seasonal and interannual variability of the southern East Sea ecosystem. By using a four-compartment NPZD model coupled with a 3D physical model, three numerical experiments were conducted with different lateral boundary conditions of nutrient flux through the KS. The results suggest that the nutrient flux through the KS may contribute to primary productivity in the southern East Sea. The magnitude of phytoplankton blooms is also influenced by this nutrient transport. We discuss the direct or indirect contribution of the nutrient flux through KS to the primary productivity of the southern East Sea.t that large amounts of dissolved inorganic nitrogen and phosphorus, comparable to the levels in the Changjiang water and the Taiwan Strait, are transported through the eastern channel of the KS, with considerable interannual variation.
