The Role of Pacific Marginal Seas
in Linking Adjacent Land with Ocean


To understand Earth systems, it is important to understand how the land and the ocean are linked, and marginal seas are key sites where such linkage occurs. The South China Sea, the East China Sea, the Japan Sea, the Sea of Okhotsk, and the Bering Sea, i.e., marginal seas along the northwest rim of the Pacific Ocean, are all strongly influenced by the land via river discharges, which also reflect human influences. Compared with other oceanic regions, marginal seas have high productivity and biogeochemical cycling activity, which are controlled by separate local processes, such as freshwater discharge, interior current systems, tidal mixing, local upwelling, interactions with the continental shelf, sea ice production and melting, and flow through straits. Further, some marginal seas have been shown to have a strong influence on physical and biogeochemical processes in the open Pacific Ocean. Therefore, it is important to investigate the role that marginal seas play in linking the land with oceanic regions to clarify the whole Pacific Ocean system.

In this program, we would like to discuss the linkage of the land and the ocean, and the roles of marginal seas, from scientific aspect.
