A pronounced deep water cooling in the Indian Ocean during ~ 3.3 – 2.3 Ma linked to a major increase in Antarctic ice volume

Benthic foraminifera population abundance and stable isotope data from ODP Site 709. The dataset has been used to reconstruct the bottom water changes in the Indian ocean since 6.5 Ma.来自大洋钻探计划（Ocean Drilling Program, ODP）709站位的底栖有孔虫（Benthic foraminifera）种群丰度与稳定同位素数据集。该数据集已被用于重建6.5 Ma以来印度洋的底层水变化。
