Oxygen-isotope records, age-model results and sedimentation rates of core MD88-784
Core MD88-784 was recovered during the French ASPARA IV cruise in 1988, aboard the Marion Dufresne. The core was located on the Tasman Fracture Zone of the Mid-Ocean Ridge, within the Polar Front Zone. \n\nIsotopic analysis was performed on tests of the planktonic foraminifera Neogloboquadrina pachy...
