Priority: 2
Position: 64°28.32'S, 65°35.27'W
Water Depth: 530 m
Sediment Thickness: >1000 m
Approved Maximum Penetration: 620 mbsf
Seismic Coverage: Site located on Line AI95-149 SP 1520; Line AMG845-03 SP 1290; intersect
Line BAS878-18 SP 3380; Intersect at 1900 m off site Ewing SAP1.
Objectives: The objectives of Site APSHE-11A 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. The alternate site is APSHE-12A.
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. Volcaniclastics sandstones and mudstones below IS1/IS2 boundary.
