The Determination of Sedimentary Cores, Oxygen and Carbon Isotope and "YD" Event in Central Okinawa Trough

In this paper, the determination and analysis of oxygen and carbon isotopes were carried out on 155 core and 180 core respectively. These data provides us with a fundamental understanding of the paleotemperature and paleoenvironmental evolution features and climate-stratigraphic classification of central Okinawa Trough since the late-glacial.
