在对冲绳海槽中部近底DGKS9603岩心有孔虫分析和加速器质谱放射性碳定年分析的基础上，利用有孔虫分析和FP-12E传递函数计算，得到了地表水温与深度关系的振荡曲线。整个岩心有7个冷相和8个暖相。全新世中、晚全新世低温事件、YD、H1、H2、H3和H4事件的明显表达以及末次冰期中期的短冷期，暗示了SO kaBP以来的短移具有全球意义。冷期沉积速率通常比暖期快，而全新世沉积速率最低，这可能与海平面上升和黑潮主轴西移有关。冲绳海槽第四纪火山活动十分发达，火山玻璃和浮石保存较好。
Based on the analyses of foraminifer and accelerator mass spectrometer radiocarbon dating in DGKS9603 core from mid-Okinawa Trough close to bottom, oscillation curve, which expressed the relation between the surface water temperature and the depth, has been obtained by using foraminifer analysis and calculation of FP-12E transfer function. The whole core indicated seven cold phases and eight warm phases. Obvious expression of low temperature event during Middle and Late Holocene, YD, H1, H2, H3 and H4 events, as well as the short cold phase during the middle last glacial period, implied that short shifts since SO kaBP would have been global significance. Sedimentation rate during cold phases is usually faster than that in warm stages, with the lowest rate in Holocene, which may be connected with rising sea level and principal axial of Kuroshio Current moving to west. Volcanic activities highly developed in Okinawa Trough during the Quaternary period, thus abundant volcanic glass and pumice were well preserved.
