On June 15th afternoon, we met Dr Karu of Peradeniya University of Sri Lanka, for research updating and a discussion about a new ANSO proposal. Huanfang gave a presentation updating the CKDu ancient water tank (AWT) results, which is fascinating. We want to work on more sediment cores and more analytes to further confirm the story. We then had a discussion on possible topic for the new ANSO proposal which will be submitted in mid July from the Sri Lankan side. Li Jun, Guangcai, Huanfang attended the meeting; Shizhen chaired the meeting. It is wonderful to meet old friend again, although online.
