Site: SCS-1
Track line for SCS-1
through SCS-5E
Seismic for SCS-1
Seismic #2 for SCS-1
Priority:
1
Position: 20°03.18ŽN, 117°25.14ŽE
Water Depth: 2050 m
Sediment Thickness: ~760 m
Approved Maximum Penetration: 450 m
Seismic Coverage: Intersection of SO-95 Profiles 10 and 20
Objectives
1.To recover a continuous sequence of high accumulation rate hemipelagic sediments to reconstruct the Pleistocene paleomonsoon history on a millenial (or higher resolution) time scale.
2.To identify the time scales of variability for sediment characteristics and accumulation rates. The time series of sediment variability will be compared with records of orbital-scale and higher frequency records from ice cores, marginal seas, and terrestrial deposits.
3.To establish a high-resolution record of SST changes associated with the winter monsoon and for comparison to the SST history of the southern SCS.
Drilling Program: Triple APC to refusal, XCB to 450 mbsf
