Peterson 9302614 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.
