Acknowledgements We would like to thank the crew of the DONGHAI cruise of the R/V l’Atalante in the East China Sea in 1996 for their support in sampling cores DGKS9603 and DGKS9604. We are indebted to Feng Guo for carrying out the clay mineral analyses of core DGKS9603. We are grateful to Yoshiki Saito for sharing core DGKS9603 tephra heavy mineral analyse results. Reviews by Burg Flemming and two anonymous referees substantially improved this manuscript. This study was funded by the NSFC (grant no. 40421150011; 40431002), MOST (grant no. 2003cb716706), and SOA, China, as well as IFREMER, France.

N2 - Based on new and existing data on oxygen isotopes, alkenone-surface seawater temperature trends, planktonic foraminifers, lithology, and clay mineral composition of piston cores, a distinct cooling event has been identified around 8,200 cal a B.P. in the middle Okinawa Trough, northwest Pacific. This corresponds to the 8,200 a B.P. cooling event recorded in many places of the Northern Hemisphere. During this event, the local temperature decreased by 1°C and the δ18O value increased by 0.6‰. A strengthened Asian winter monsoon is the most probable cause for this event, which thus adds further credibility to the contention that we are dealing here with a global phenomenon.
