| Research Abstract |
We developed a low-trophic ecosystem model for the East China Sea and Seto Inland Sea, respectively, clarified the transport and cycle processes of land-source and ocean-source nutrients, and calculated their contributions to annual primary production in the seas. Using historical observation data, we revealed the spatial and temporal variations in nutrient transport by the Kuroshio and the temporal variations of nutrient concentration in the middle layer of Kuroshio region, which is a background faced by two coastal seas. Furthermore, using numerical experiments, we examined the responses of standing stock of nutrients and primary in the seas to the concentration change of nutrients in the Kuroshio region and from land.
