Site: APSHE-09A

Priority: 2 (alternate to APSHE-03A)
65°56.01'S, 70°25.80'W
Water Depth:
390 m
Sediment Thickness:
>2000 m
Approved Maximum Penetration:
450 mbsf
Seismic Coverage: Site located at SP 868 of Line AI95-140; 1200 m off the site, SP 820 of Line AI95-140 intersects SP 610 of Line AI95-142; Line AMG878-19 is nearby.

The objectives of Site APSHE-09A are to:

1. Identify and date the main changes in wedge geometry during progradation of the glacial wedge (onset of erosional 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
