Abstract
Among the low to mid latitude western Pacific marginal seas are the South China Sea (SCS), Sulu Sea and Sea of Japan, the three major enclosed seas in the region with passages connecting to the open ocean. The passage sill depths are ∼130m for the Sea of Japan, ∼420m for the Sulu Sea, and ∼2,400m for the SCS. Therefore, water exchanges with the deeper ocean are more effective in the SCS than in other sea basins. The last 30 Ma deep water history since seafloor spreading in the SCS is a history of basin evolution relating especially to subsidence and sediment preservation, as well as changes in deep water properties. The long sequence recovered at ODP Site 1148 provides a unique opportunity to trace this history. In this chapter, we overview recent progresses of deep water research in the region by focusing on benthic foraminiferal, ostracod and isotopic geochemistry records from Site 1148.
