| Research Abstract |
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).
