Stable isotope record of planktonic foraminifera from the Sulu Sea, supplement to: Linsley, Braddock K; Thunell, Robert C (1990): The record of deglaciation in the Sulu Sea: evidence for the Younger Dryas event in the tropical western Pacific. Paleoceanography, 5(6), 1025-1039
A high-resolution, accelerator mass spectroscopy 14C dated sediment record from the Sulu Sea clearly indicates that the Younger Dryas event affected the western equatorial Pacific. Planktonic foraminiferal delta18O and abundance data both record significant changes during Younger Dryas time. In part...
