Stable isotope samples were micro-milled continuously at ~40 um intervals from 235.3 cm to 231.9 cm of HS-4 with an average resolution of ~0.3 years. A total of 869 samples were measured on a Thermo Delta V Advantage Isotope Ratio Mass spectrometer fitted with a Kiel Carbonate Device IV at Oxford Department of Earth Sciences, with a precision of ±0.08 per mil. The chronology of stalagmite HS-4 during 8.2 kyr event has been established independently by U-Th dating (9 samples measured by MC-ICP-MS at Oxford University) and layer counting. Full details of the chronology and age model are provided in Supplementary Information of Liu et al. 2013. ABSTRACT SUPPLIED BY ORIGINATOR: An abrupt cooling event in the North Atlantic region 8,200 years ago affected climate throughout the Northern Hemisphere. The event is well constrained in Greenland ice cores, but lack of resolution in records from other regions has challenged our understanding of the timing and nature of the associated teleconnections. Speleothem records from East Asia have suggested monsoonal changes associated with the 8,200 year event, but the nature of these changes remains controversial. Here we assess changes in East Asian precipitation during the event from a sub-annually resolved stalagmite record from central China. Using d18O and Mg/Ca measurements of the speleothem carbonate, we show that climate dried significantly about 8,200 years ago. Based on our annual-layer-counted chronology, we show that the dry event lasted 150 years, with a central period of pronounced aridity that lasted 70 years. The duration and evolution of the event is indistinguishable from that observed in the Greenland ice cores. We therefore conclude that an effective and rapid atmospheric teleconnection exists between the North Atlantic and the monsoon system in warm climates similar to today's.
