Site: SCS-4
Track line for SCS-1
through SCS-5E
Seismic for SCS-4 (revised 1 February
1999)
Priority:
1
Position: 19°27.24'N, 116°15.84'E
Water Depth: 2093 m
Sediment Thickness: 1400 m
Approved Maximum Penetration: 520 m
Seismic Coverage: Intersection of SO-95 Profile 5
Objectives:
1.To recover a continuous sequence of hemipelagic sediments to reconstruct the middle Miocene to Pliocene paleomonsoon history.
2.To identify if monsoonal indices intensify or weaken during the middle to late Miocene as a test of monsoon evolution models.
3.To establish if Miocene-Pliocene pattern of accumulation rates are consistent with models of HTC uplift, monsoon intensification, and sea-level changes.
Drilling Program: Triple APC to refusal, XCB (possibly double XCB) to 520 mbsf
Logging and Downhole Operations: Triple-combo, GHMT, and sonic-FMS
Nature of Rock Anticipated: Hemipelagic mud and silt
