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.

Shizhen and Longfei awarded Tu GuangChi Fellowships (涂光炽奖）

On Jan the 16th afternoon, Shizhen and Longfei were awarded by the institute the A-level Tu GuangChi Fellowship (涂光炽奖), after an assessment by the top academic panel of the institute. Shizhen was upgraded from B-level to A-level, while Longfei A-level directly. The Fellowship stands for the utmost recognition from the institute to outstanding young scientists, and is named after the founder of the institute, Professor Tu GuangChi, who was a distinguished geologist. Each awarded young scientist will receive a budget of 1 million Yuan for developing their early academic career.  The group now has 3 TGC fellows, all in A-level, who are Li Jibing, Zhao Shizhen and Jiang Longfei. Congratulations to Shizhen and Longfei !

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.
