Figure 4. Comparison of the relative percentage of Aragonite in the fine fraction (<63 µm) with the planktonic foraminifer oxygen isotope stratigraphy for Site 1003 (Hole 1003A). The broken lines indicate the ties between the two records, and the numbers given to the lines depict the even (glacial) isotope stages. In addition, the position of the seismic stratigraphic boundaries (SSBs), calcareous nannofossil bioevents, and the U/Th dates are marked. The U/Th dates are given as marine oxygen isotope stages (MIS). For details of how they were assigned to the raw U/Th dates see Henderson et al. (Chap. 3, this volume). PDB = PeeDee belemnite standard.
