High‐resolution (104 years) deep‐sea foraminiferal stable isotope records of the Eocene‐Oligocene climate transition
We have constructed high‐resolution (104–105 years) benthic foraminiferal δ13C and δ18O
records for the upper Eocene through lower Oligocene of two pelagic sequences, Deep Sea
Drilling Project (DSDP) Site 522 in the Angola Basin, South Atlantic Ocean, and Ocean
Drilling Program (ODP) Site 744 in the southern Indian Ocean. These records provide
improved constraints on both the timing and magnitude of marine oxygen and carbon
isotope events from 30 to 35 Ma. The oxygen isotope records indicate that the ubiquitous …
