(Table 1) Gas tie points used to correlate the ice cores NGRIP and EDML@en

Water isotope records from the EPICA Dronning Maud Land (EDML) and the NorthGRIP ice cores have revealed a one to one coupling between Antarctic Isotope Maxima (AIM) and Greenland Dansgaard-Oeschger (DO) events back to 50 kyr. In order to explore if this north–south coupling is persistent over Marine Isotopic Stage 5 (MIS 5), a common timescale must first be constructed. […]来自EPICA毛德皇后地冰芯（EPICA Dronning Maud Land, EDML）与北格陵兰冰芯计划（NorthGRIP）的冰芯水同位素记录显示，在距今5万年以来，南极同位素最大值（Antarctic Isotope Maxima, AIM）与格陵兰丹斯果-奥什格尔（Dansgaard-Oeschger, DO）事件之间存在一对一的耦合关系。为探究该南北半球耦合关系在海洋同位素阶段5（Marine Isotopic Stage 5, MIS 5）期间是否持续存在，首先需要构建统一的时间标尺。[…]
