Millennial-scale Asian monsoon variability during MIS 9 revealed by a high-resolution stalagmite δ18O record in Luoshui Cave, central China

A new high-resolution oxygen records from Chinese cave as well as a composited MIS9 Asian monsoon record. A 67-yr-resolution δ18O profile of a 230Th-dated stalagmite from Luoshui Cave, central China, is presented to refine the Asian summer monsoon (ASM) history from 336 to 290 kyr BP. The sub-stages of Marine Isotope Stage 9 (MIS 9) are clearly reflected in the Luoshui δ18O record, in line with changes in the Northern Hemisphere summer insolation (NHSI).

一项新的高分辨率氧同位素数据集，源自中国洞穴，以及合成亚洲MIS9季风记录。本文展示了来自中国中部洛水洞的230Th年代测定的洞穴石笋的67年分辨率的δ18O剖面，旨在精细刻画从336至290千年前（BP）的亚洲夏季季风（ASM）历史。海洋同位素阶段9（MIS 9）的亚阶段在洛水δ18O记录中清晰体现，并与北半球夏季太阳辐照度（NHSI）的变化相吻合。
