9. Diatom
response to climate forcing of a deep, alpine lake (Lugu Hu, Yunnan, SW China)

monsoon variability
Qian Wang, Xiangdong
Yang, N. John Anderson, Enlou Zhang, Yanling Li
Volume 86, 15 February
2014, Pages 1–12

high-resolution diatom record from a deep alpine lake of SW China is presented.

events (such as YD) are not captured in the diatom and pollen records.
