Priority: 1
Position: 63°52.93'S, 65°42.69'W
Water Depth: 440 m
Sediment Thickness: >2000 m
Approved Maximum Penetration: 600 mbsf
Seismic Coverage: Explora Line AI95-152 and Discovery Line AMG845-08
Objectives: The objectives of Site APSHE-03A are to:
1. Identify and date the main changes in wedge geometry during the progradation of the glacial
wedge (onset of erosional S1/S2 boundary).
2. Examine topset (S1) and foreset (S2) lithologies and compare with the rise drift.
Drilling Program: Single RCB hole to 505 mbsf. Alternate site is APSHE-09A.
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 in foresets) with thin biosiliceous interbeds.
Note: seismic line same as Site APSHE-01A
