Site: PBD-13A

To PBD-13A Line RAE 40006
To Figure 8 for cross line

Priority: 2 (alternative to PBD-12B)
Position: 63°59.807´S, 070°56.519´E
Water Depth: 3450 m
Sediment Thickness: >2 km
Target Drilling Depth: ~1020 mbsf
Approved Maximum Penetration: 1150 mbsf
Seismic Coverage: SAE 33007 SP 429, RAE 40006 SP 117.


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: Same as for PBD-12B.


Logging Program: Same as for PBD-12B.


Nature of Rock Anticipated: Mud, ooze, fine sand, and ice rafted pebbles
