Indian Summer Monsoon multi-proxy records from the Bay of Bengal across Marine Isotope Stage 5

Multi-proxy records from two deep-sea sediment cores (IODP 353-U1446 and U1448) of the stable oxygen isotope composition (N. dutertrei) and trace element ratios (G. ruber ss, N. dutertrei) measured in planktic foraminifera, foraminiferal percent abundance and bulk sediment elemental variations gained from portable-XRF. These records are inferred to capture Indian Summer Monsoon river runoff across Marine Isotope Stage 5/6 (70-140 thousand years ago).

本数据集包含来自两个深海沉积物岩芯（国际大洋发现计划（International Ocean Discovery Program, IODP）353航次U1446孔与U1448孔）的多代用指标记录，所涵盖指标包括：从浮游有孔虫（planktic foraminifera）中测得的稳定氧同位素组成（新哲丁氏抱球虫*N. dutertrei*）、微量元素比值（红拟抱球虫*G. ruber ss*、新哲丁氏抱球虫*N. dutertrei*）、有孔虫百分丰度，以及通过便携式X射线荧光光谱仪（portable-XRF）获取的沉积物全样元素变化。上述代用记录被推断用于反演海洋同位素阶段5/6（Marine Isotope Stage 5/6，距今7万至14万年）期间的印度夏季风（Indian Summer Monsoon）河流径流特征。
