Figure F7. Bulk oxygen isotopes at Site 1219 and CaCO3. We observe a general correlation of high oxygen isotopes with high CaCO3. For carbonate accumulation event (CAE)-2 (45.9–44.2 Ma) and CAE-3 (42.2–40.5 Ma), especially, we observe high CaCO3 correlates with high oxygen isotopes. The CAE intervals coincide with cool conditions and/or polar ice. PDB = Peedee belemnite.
