Site: SCS-5E
Track line for SCS-1
through SCS-5E
Seismic for SCS-5E
Priority:
1
Position: 19°0.36'N, 116°35.88'E
Water Depth: 3143 m
Sediment Thickness: 1160 m
Approved Maximum Penetration: 770 m
Seismic Coverage: SO-95 Profile 20
Objectives:
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 Oligocene-Miocene interval.
3.To establish if Oligocene-Miocene pattern of accumulation rates are consistent with models of HTC uplift, monsoon intensification, and sea-level changes.
