Intermediate-deep ocean environments since the last glacial period(after 20, 000 years ago) were reconstructed using well-dated sediment cores from the East China Sea and Philippine Sea around the Okinawa Islands, Japan. According to microfossil record(Radiolaria) and geochemical analysis, it is suggested that the northern origin intermediate water might intrude in this area during transition period from the last glacial to Holocene(17, 500 to 11, 500 years ago).

利用日本冲绳岛附近的东海和菲律宾海沉积物岩心，重建了自末次冰期（2万年前以后）以来的中深海环境。根据微化石记录（放射虫）和地球化学分析，认为在末次冰期到全新世的过渡时期（17,500 ~ 11,500年前），该区可能有北部起源的中间水侵入。
