The age versus depth profile for core GC04, located off the coast of New Caledonia

Core GC04, was collected from the southeastern side of the New Caledonian Basin (22.99965 S, 166.150716 E). The age of the sediment at each sample depth was determined by correlating oxygen isotopes to the Martinson et al. (1987) age model. This information can then be used to infer sedimentation rates. The results indicate that core GC04 is characterised by slow sedimentation rates. The average sedimentation rate is 1.46cm/kyr. The minimum sedimentation rate is ~0.03cm/Kyr, occurring at around MIS 5c and maximum ~4cm/Ka occurring around MIS 5e.GC04岩心采集自新喀里多尼亚盆地东南侧（南纬22.99965°，东经166.150716°）。各采样深度处沉积物的年代，通过将氧同位素记录与Martinson等人1987年提出的年代模型进行对比确定。据此可推断沉积物的沉积速率。研究结果表明，GC04岩心整体沉积速率偏低，其平均沉积速率为1.46厘米每千年（cm/kyr）。最低沉积速率约为0.03厘米每千年（cm/Kyr），出现在深海氧同位素阶段（Marine Isotope Stage，MIS）5c附近；最高沉积速率约为4厘米每千年（cm/Ka），出现在MIS 5e附近。
