THE FIRST SAMPLING CAMPAIGN OF THE GEOBBC PROGRAM

From 31 October to 1st November, we carried out the first sampling campaign of the GeoBBC program in Dongjiang River. The first sampling site is Huangtian Reservoir, Dongjiang River (Yihe Hydropower Station), where we collected 50 L of surface water and surface sediments. After that, we explored other sampling sites along the Dongjiang River for the preparation of the upcoming large-scale sampling. Participants including Prof. ZHANG GAN, Prof. LI JUN, Prof. ZHAO SHIZHEN, Prof. SUN YANMIN, HU ZHICHENG and GENG XIAOFEI, enjoyed this campaign very much. In addition to precious samples, we also harvested the pleasant scenery and graceful mood along the way. The jade-green bamboo grove, the snow-white reeds sea, our heart beguiles. The intoxicating scenery triggered Prof. Zhang’s poetic sentiment. There is an exquisite poem created by Prof. Zhang:
【东江初试】
秋风吹玉水,
苇絮躜沙汀。
塘坝山湾远,
轻舟陌岸横。
灵芝称小院,
喧竹挹江青。
忽报台风至,
忍兴启归程。
