Murray 9302496 The PIs will use faunal, geochemical and stable-isotopic data to reconstruct climatic changes in the Indian Ocean between 12 and 3.5 Ma utilizing ODP core material. The study will lead to delineation of surface temperature gradients, productivity, and the signature of biogenic sedimentation. It will also provide a time series of monsoonal upwellinmg in the northwestern Indian Ocean that may be associated with the uplift of the Himalayas and the Tibetan Plateau.

Murray 9302496 PI将使用动物群、地球化学和稳定同位素数据，利用ODP核心材料重建12至3.5 Ma之间印度洋的气候变化。这项研究将导致对地表温度梯度、生产力和生物沉积特征的描绘。它还将提供西北印度洋季风上升的时间序列，这可能与喜马拉雅山和青藏高原的隆升有关。
