1.To recover a continuous sequence of hemipelagic sediments to reconstruct the paleoclimate history from Oligocene to Miocene.

2.To identify the onset of monsoonal variability in the SCS and to establish its evolution in the Oligo-Miocene interval.

3.To establish if Oligo-Miocene pattern of accumulation rates are consistent with models of HTC uplift, monsoon intensification, and sea-level changes.
