GeoBBC Progress – Phase 3 Dry Season Sampling Completed

Following the completion of the sampling of the first two stages, the GeoBBC sampling of the third stage in dry season has been completed. From February 11 to 16, 2023, Professor Zhang Gan, Professor Li Jun, Associate Professor Zhao Shizhen, Xiaofei, Bolong and Zhicheng collected 8 surface sediment samples, 11 large water samples (~ 60L/sample) and 26 small water samples (~ 1L/sample) from the Xinfengjiang Reservoir and the river inlet. The large water samples include 8 surface water samples (2m) and 3 deep water samples (20m or 40m). The small water samples include 19 surface water samples (2m) and 7 deep water samples (20m, 40m and 60m). In addition, We set up 15 passive air samplers (3 samplers*5 sampling sites) and 1 atmospheric deposition sampler.

Dry Season Sampling of GeoBBC Program Achieved a Phased Success

GeoBBC Sampling in Dry Season mainly includes four stages, and the first two stages have been completed. In the first stage (from 14 Nov. to 26 Nov.), Xiaofei, Bolong and Zhicheng collected the surface water and sediment samples from the main stream of the Dongjiang River (12 sampling sites) and Qiuxiangjiang River (2 sampling sites). In the second stage (from 12 Dec. 2022 to 8 Jan. 2023), the same sampling team collected surface water and sediment samples from Xinfeng River (3 sampling sites), Daxi River (5 sampling sites), Lianping River (6 sampling sites) and Zhongxin River (8 sampling sites). In total, 36 water samples and 25 sediment samples were collected. Among which, basic water quality parameters such as pH, conductivity and ammonia-nitrogen concentrations have been determined. In addition, 28 water samples have been filtered and enriched to obtain particulate matter (PM) and dissolved organic matter (DOM), respectively. Pro. Zhang, Pro. Li and associated Pro. Zhao also participated in this campaign with strategic significance.

In the second stage, Tang Jiao and the GeoBBC sampling team set up 30 passive samplers in the Dongjiang River Basin, mainly distributed in Xinfeng County (4 sampling sites), Lianping County (5 sampling sites) and Dongyuan County (1 sampling site). Three samplers were installed at each sampling site to obtain parallel samples.

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。
