A preliminary δ¹⁸O biostratigraphic framework was established by omitting a further 12 data points affected either by unusually low δ¹⁸O values likely due to freshwater impact or by rapid δ¹⁸O increases due to diagenetic overprinting across slumped/unslumped sediment boundaries. Comparison between isotopic results from Hole U1322B and other tropic records from the region indicates that the sediment sequence recovered in Hole U1322B was mainly deposited during MIS 1, 2, 3, and 4, separable at 23 (MIS 1/2), 89 (MIS 2/3), and 200 mbsf (MIS 3/4), respectively. A more detailed correlation with other deep sea records requires further high-resolution studies. Top of page \| Previous \| Next
