To Seismic PBD-12B line SAE 33006
To PBD-12B Line SAE 33007
Position: 64°22´46.5"S, 067°13´7.5"E
Water Depth: 3525 m
Sediment Thickness: >2 km
Target Drilling Depth: ~1020 mbsf
Approved Maximum Penetration: 1140 mbsf
Seismic Coverage: SAE 33006 SP 855 (Moved from intersection with SAE 33007 to avoid closure formed by drift topography)
Objectives: To obtain a cored section to the base of the sediment drift on the continental rise to date the major change in sedimentation that led to drift formation (Oligocene?) and to compare the history of sedimentation on the shelf and slope with oceanic sedimentation on the rise.
Drilling Program: APC Hole A to refusal (~200 mbsf), continue with XCB to refusal (~570 mbsf) then RCB Hole B to ~1020 mbsf.
Logging Program: Quad combo (BHC, HLDT, DITE, and sonic) and GHMT
Nature of Rock Anticipated: Mud, ooze, fine sand, and ice-rafted pebbles
