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
