Priority: 2 (alternate to APSHE-02A)
Position: 65°54.98'S, 70°28.46'W
Water Depth: 405 m
Sediment Thickness: >2000 m
Approved Maximum Penetration: 450 mbsf
Seismic Coverage: Site located at SP 758 of Line AI95-140; 1550 m off the site, SP 820 of Line AI95-140 intersects SP 610 of Line AI95-142; Line AMG878-19 is nearby.
Objectives: The objectives of Site APSHE-08A are to:
1. Identify and date the main changes in wedge geometry during progradation of the glacial
wedge (conformable S1/S2 boundary).
2. Examine topset (S1) and foreset (S2) lithologies and compare with rise drift.
Drilling Program: Single RCB hole.
Logging and Downhole Operations: Standard suites IPLT-DLT and FMS-sonic, plus GHMT.
Nature of Rock Anticipated: Diamicton (alternations of lodgement till in topsets and proximal glacial marine) with thin biosiliceous interbeds.
Note: seismic line same as Site APSHE-07A
