Age vs. Depth of core MD032607 (off South Australia). Age has been calculated through modelling based on oxygen isotope records from Globigerina bulloides

The age with depth of core MD032607 is calculated through 18O values, which are then correlated with the SPECMAP age-model. Based upon these measurements the age at the deepest part of the core (3270cm) is ~176,590yrs BP. The age vs. depth profile for this core indicates a major increase in the sedimentation rate during the initial phase of MIS 6, when the sedimentation rate is ~41cm/1000yrs. The average sedimentation rate over the length of the core is 18.7cm/1000yrs.

岩芯MD032607的年代-深度序列通过氧-18同位素比值计算得到，并将该序列与SPECMAP年代模型（SPECMAP age-model）进行比对校准。基于上述测定结果，该岩芯最深处（3270cm）的年代约为距今176590年（yrs BP）。该岩芯的年代-深度剖面显示，在深海氧同位素阶段6（MIS 6）初期，沉积速率出现显著跃升，彼时沉积速率约为41厘米/千年。该岩芯全长的平均沉积速率为18.7厘米/千年。
