Evolution of the Asian summer monsoon during Dansgaard/Oeschger events 13-17 recorded in a stalagmite constrained by high-precision chronology from southwest China
A stalagmite with high U-238 content from Yangkou Cave, China, revealed the evolution of the Asian summer monsoon (ASM) between 49.1 and 59.5 ka, and the delta O-18 values recorded Dansgaard/Oeschger (D/O) events 13-17. The Yangkou record shows a relatively gradual transition into the D/O 14 and 16...

A stalagmite with high U-238 content from Yangkou Cave, China, revealed the evolution of the Asian summer monsoon (ASM) between 49.1 and 59.5 ka, and the delta O-18 values recorded Dansgaard/Oeschger (D/O) events 13-17. The Yangkou record shows a relatively gradual transition into the D/O 14 and 16 events. The discrepancy between the abrupt and gradual transitions of D/O 14 in the records from northern and southern China, respectively, suggests different responses of the ASM to climate changes in the high northern latitudes. The higher resolution delta O-18 record and more precise Th-230 dating indicate that the timing of D/O 14 and 17 in the Hulu records at 53 and 58 ka should be shifted to 54.3 and 59 ka, respectively. The gradual strengthening of the ASM at the onsets of D/O 16 and 14 in our record is different from the abrupt temperature rise in the northern high latitudes.
