| Outline of Final Research Achievements |
It is known that unique oceanic circulation in the Japan Sea is sensitively responded with climatic and sea-level changes during the Pleistocene period. In addition, topographic evolution of the Japanese archipelago with local tectonics is another important factor for controlling the oceanic circulation. In this study, we examined microfossils in deep-sea drilling cores obtained from 7 sites in the Japan Sea and 2 sites in the northern East China Sea during IODP Expedition 346, in order to reconstruct paleoenvironment in the Japan Sea during the past 500 million years.
