冲绳海槽DGKS9603孔岩芯δ18O曲线记录了50 kaBP以来的气候波动以及短尺度的古气候突变事件. 这些古气候事件可以与中国西北黄土、南海与北大西洋岩芯以及格陵兰冰芯记录的YD, H1, H2, H3, H4, H5事件对比. 古地磁分析的3个地球磁极倒转事件可分别与Gothenburg Mungo和Laschamp事件对应, 并大致可与H1, H3, H5事件对应, 这可能是造成全球气候变化的一个原因. 冲绳海槽岩芯δ18O曲线与李家塬黄土的粒度曲线有很好的对应关系, 与格陵兰冰芯记录的气候波动有某些差异, 表明还存在地域性的因素控制着两者的变化, 在东亚地区季风可能是一个主要的因素.
The δ18O curve of the hole core DGKS9603 in the Okinawa Trough recorded the climatic fluctuations since 50 kaBP and the short-range paleoclimatic events that can be correlated with the YD recorded by the Northwest Loess, South China Sea and North Atlantic cores and the Greenland ice core, H1, H2, H3, H4 and H5 events.The three earth-pole reversal events of paleomagnetic analysis can correspond to the events of Gothenburg Mungo and Laschamp, respectively, and correspond roughly with the H1, H3 and H5 events, which may be caused by the global climate One reason for the change is that the δ18O curve of the Okinawa Trough core has a good correspondence with the grain size curve of the Lijianyuan loess and some differences with the recorded climatic fluctuations of the Greenland ice core, indicating that there are still some regional factors controlling the Changes in the East Asian monsoon may be a major factor.
