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 particular, a 0.4 per mil increase in the delta18O value of Globigerinoides ruber and the reappearance of the cool water planktonic foraminifera, Neogloboquadrina pachyderma, occur during the Younger Dryas at this location. These isotopic and...
