Abstract

Planktonic foraminiferal δ18O, AMS14C ages and U37k derived sea surface temperature (U37k-SST) were analyzed at the gravity core E-2 from the northern Philippine Sea (29.62°N、131.14°E,water depth 3 877 m, core length 282 cm). The results record the history of U37k-SST variations since 19 cal kaBP. On the whole, the pattern of last deglaciation warming is similar to that in the high-latitude North Atlantic region, implying a climate tele-connection between the northern Philippine Sea and high-latitude North Atlantic. Some climate events are recognized such as Heinrich 1 (H1), Bølling/Allerød (B/A), Younger Dryas (YD), and other two cold events at 19.4~19.2 and 18.5~18.0 cal.kaBP respectively. The centennial-scale U37k-SST variations are superimposed on the B/A and YD periods, probably suggesting a tropical influence on the study area. We also found that the last deglaciation warming probably began at~19.4 cal.kaBP, and the more rapid warming started at~15.3 cal.kaBP.
