• 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
