ABP. Sedimentation rate is very low on the whole core and shows three apparent variations at three phases:① A comparatively high SR during marine isotope stage 3 (MIS3) and LGM, about 7.3 and 14cm/ka respectively;② A very low SR of 1.5cm/ka during the last deglaciation, which is different from the deeper Okinawa Trough with higher SR during the last deglaciation than the last glaciation;③ A negligible sediment accumulation since 6.4 cal.

DOC-42孔沉积速率整体较低，呈明显的阶段性变化：在氧同位素3期和LGM期间沉积速率相对较大，分别为7.3和14cm/ka；末次冰消期以来的沉积速率则显著降低，与冲绳海槽冰后期沉积速率高于末次冰期明显不同；自约6.4 cal。
