| Objectives
(see text for complete details): |
• Recover millennial-scale marine reference section for the Pleistocene
• Provide marine sediment analog to the polar ice cores
• Reconstruct deep water circulation changes (i.e., mixing ratio of southern and northern component water)
• Facilitate marine-terrestrial correlations
• Construct an integrated stratigraphy

| Drilling/coring program: |
Quadruple APC to refusal, drillover
Temperature measurements: APCT-3 |
| Downhole logging program: |
None |
| Anticipated lithology: |
Hemipelagic muds |
