Before the end of sampling in the dry season, Professor Zhang Gan invited Professor Zou Shichun, Dean of the School of Oceanology, Sun Yat-sen University, to visit Director Tian Zhaowei of Heyuan Hydrology Station. Along with them was the GeoBBC Sampling Squad (Professor Li Jun, Associate Professor Zhao Shizhen, Xiaofei, Bolong and Zhicheng). We had an in-depth discussion on sampling arrangements. Professor Zou and Director Tian gave professional suggestions, which greatly improved our sampling plan. Based on this discussion, we identified Shuntian Hydrological Station (顺天水文站), Heyuan Hydrological Station (河源水文站) and Boluo Hydrological Station (博罗水文站) as long-term sampling sites, and conducted field investigations on these preset sampling sites. What is exciting is that we successfully collected three sedimentary columns (~80 cm) in Fengshuba Reservoir (枫树坝水库). It was a really rewarding trip. Cheers!
