Abstract:
To document the evolution of the early cryosphere, stable isotope analyses were conducted on the planktonic and benthic foraminifers from Ocean Drilling Program Site 1218. We generated two parallel 54-m-long records at 10-cm resolution and thus produced a standard Pacific stable isotope reference curve for the 26.4- to 30.0-Ma interval within the Oligocene. These data are necessary to document the timing and magnitude of glacial events through the Oligocene. Pronounced variations are recorded in both planktonic and benthic foraminifer delta (super 13) C between +0.32% and +1.67% and -0.18% and +1.09%, respectively. There is an overall increase in delta (super 18) O though the record, toward heavier values in the late Oligocene.
