Site: APSHE-12A

Priority: 2 (alternate to APSHE-11A)
Position: 66°46.55'S, 69°33.35'W
Water Depth: 375 m
Sediment Thickness: >1000 m
Approved Maximum Penetration: 620 mbsf
Seismic Coverage: Line PD88-04 (0830/002). Intersection: Line IT92-111 SP 1125.

Objectives: The objectives of Site APSHE-12A are to:

1. Obtain a record of "pre-glacial" sedimentation in the inner shelf basin.

2. Provide constraints on the history of vertical motion associated with ridge-crest collision.
Drilling Program: Single RCB hole.

Logging and Downhole Operations: Standard suites IPLT-DLT and FMS-sonic, plus GHMT.

Nature of Rock Anticipated: Diamicton intercalated with thin hemipelagic layers down to IS1/IS2 boundary. Volcaniclastic sandstones and mudstones below IS1/IS2 boundary.

Note: seismic line same as Site APSHE-05A
