The objectives of Site APSHE-02A 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 to 560 mbsf. Alternate site is APSHE-08A.

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

Nature of Rock Anticipated: Diamicton (alternations of lodgement till in topsets and proximal glacial marine) with thin biosiliceous interbeds.
