A Late Quaternary Planktonic Foraminiferal Oxygen Isotope Record of the Banda Sea: Chronostratigraphy, Orbital Forcing, and Paleoceanographic Implications

Abstract

A detailed oxygen isotope time-scale based on planktonic foraminifera Globigerinoides sacculifer at site MD012380 in the Banda Sea was established for the past 820 kyrs by correlating the record to the astronomically tuned benthic oxygen isotope chronology of MD972143. Ages for marine isotope stratigraphic (MIS) events from 2.0 back to 21.1 were designated for this western tropical Pacific record.
