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.
