Data report: revised Pleistocene age model based on a modified nannofossil bioevent and additional measurements of benthic foraminiferal oxygen and stable carbon isotope ratios from Hole U1352B, offshore Canterbury Basin, New Zealand

Abstract

Reexamination of a nannofossil datum, the highest occurrence of Pseudoemiliania lacunosa (Zone NN20/NN19; 0.44 Ma), has led to a revised datum depth in Integrated Ocean Drilling Program Expedition 317 Hole U1352B. Furthermore, comparison between isotopic ratios of benthic foraminifers Nanionella flemingi and Uvigerina perigrina indicate that oxygen and carbon isotopic ratios for both species, when they occur in the same horizon, are almost identical. Therefore, we can correlate the oxygen isotopic variations of N. flemingi with the LR04 stack. We have conducted additional measurements of oxygen and stable carbon isotope ratios of N. flemingi, which in conjunction with our revised nannofossil datum allows a new correlation with the LR04 stack and results in revision of our original age model.
