Priority: 2 (alternate to APSST-01A)
Position: 62°13.00'S, 62°53.00'W
Water Depth: 4705 m
Sediment Thickness: ~1500 m
Approved Maximum Penetration: 720 mbsf
Seismic Coverage: Line HESP92-11 SP 38900, part of coarse grid of MCS lines (cruise ANT-92).
Objectives: The objectives of Site APSST-02A are to:
1. Obtain a high-resolution Pliocene-Quaternary stratigraphy of cyclic sedimentation in the
South Shetland Trench.
2. Time glacial events and paleoceanographic processes.
Drilling Program: Double APC until refusal (about 200 m) then XCB.
Logging and Downhole Operations: Standard suites IPLT-DLT and FMS-sonic, plus GHMT.
Nature of Rock Anticipated: Turbidites.
Note: seismic line same as Site APSST-01A
