The major Cenozoic shift from a shallow (~3‒4 km) to deep (~4.5 km) calcite compensation depth (CCD) occurred at the Eocene-Oligocene Transition (EOT; ~34 Ma), suggesting a strong relationship between calcium carbonate (CaCO3) cycling and Antarctic glaciation. To further investigate the linkages between these two events, detailed records of deep-sea carbonate content, and bulk sediment and benthic foraminiferal stable isotope records are needed. This dataset contains bulk sediment stable isotope and carbonate content records from eight sites in the eastern equatorial Pacific (ODP Leg 199 and IODP Expedition 320). These records were used to reconstruct the depth of the calcite compensation depth (CCD) across the Eocene-Oligocene Transition. The projected depth of the CCD is included in this dataset. In addition, this dataset contains a monospecific epifaunal benthic foraminiferal stable isotope stratigraphy from IODP Expedition 320 Site U1334, in the eastern equatorial Pacific, across the Eocene-Oligocene ...
