NSFC major program “GeoBBC” – 2023 annual meeting

On the 16 -17th of January 2024, the 2023 annual meeting on “Black Carbon: Geochemical fate and environmental effects (GeoBBC)”, a major program of the National Natural Science Foundation of China (NSFC), was held at the Jiayi International Hotel in Guangzhou.

Li Wei (李薇), Deputy Director of the Department of Earth Sciences of NSFC, Academician Tao Shu (陶澍) from Peking University/Southern University of Science and Technology, Academician Peng Ping’an (彭平安) from Guangzhou Institute of Geochemistry, Chinese Academy of Sciences (GIG), Academician Wang Yanxin (王焰新) from China University of Geosciences (CUG), Academician Zhu Tong (朱彤) of Peking University,  Professors Pan Bo (潘波) of Kunming University of Technology, Zhu Dongqiang (朱东强) and Zheng Mei (郑玫) of Peking University, and Chen Yingjun (陈颖军) of Fudan University attended the meeting as seering committee members. Professor/academician He Hongping (何宏平), Director of GIG, Tian Hui (田辉), Director of Science and Technology Department of GIG, and Zhang Gan (张干), chief scientist of the major project, as well as the project leaders and backbones attended the meeting.

The opening ceremony of the conference was chaired by Tian Hui and a welcome speech was delivered by He Hongping. In her speech, Li Wei addressed that the major project was approved in 2021 and started in 2022. The project has been running for two years, with outstanding works, rich achievements and good progress. In addition, Li Wei suggested that the project should further be in line with the national demand and the “dual-carbon” strategy, strengthen target-oriented design, and face mid-term inspections. Zhang Gan gave a general introduction to the project from the aspects of project background, major research progress in 2023, and research plan for 2024. Then Song Jianzhong, Zhang Yanlin and Wang Junjian reported the annual progress of each sub-project, respectively.

The steering committee members fully agreed with the importance of the project. At the same time, constructive suggestions were made in terms of research scopes, innovative breakthroughs and project integrity, followed by in-depth discussions among the project leaders and backbone members. In response to the questions and suggestions raised by the attending experts, the project leaders and key members had a lively exchange and discussion, which helps with the next-year research plan.

The Sampling of Salt Lakes and Playas in Northwestern and Northern Regions of China: Dream into Reality

On Dec 6th in 2023, a group of us, including Prof. Gan, Prof. Jun, Dr. Shizhen, Dr. Jiao, Zhicheng and Weiru, went on the journey to Golmud. Our marvelous ten-day journey traveled more than 10,000 km in total, streching over Qinghai Province （Qaidam Basin), Shanxi Province and Xinjiang Province（Tarim Basin) and colletcing 43 surface brine/water samples, 27 sediment samples, 19 salt  samples and 2 snow samples.We were very close to the border (cr: Prof. Gan).

The first two days of sampling campaign were for Qarhan Salt Lake （察尔汗盐湖） and Dabusun Lake （达布逊湖）, which the Golmud River (格尔木河) flows into. Prof. Gan and Prof. Jun also got involved in to collect surface brine, sediment and salt samples. We also dirved to the  Chaidan Lake （大/小柴旦湖）.

The rest of the sampling campaign was led by Dr. Shizhen, with the assistance of Dr. Jiao and Zhicheng. We four dirved to Xining for the appealing Chaka Salt Lake as well as Qing hai Lake. The weather was freezing and the sampling site could reach an altitude of 3817 m, raising the difficulty of sampling. However, we  overcame the difficulties as well as refueled each other! 🙂

The next site was Yuncheng Salt Lake （运城盐湖） in Shanxi. It was far beyond our imagination that we were unable to get close to the lake. We trudged through the reeds and finally collected the precious samples.

The last site was at Xinjiang Province. We arrived there with excited hearts (That was my first time of travelling to Xinjiang). Manas Lake (玛纳斯湖) and Ebinur Lake（艾比湖）were our targets. Manas Lake was an artificial lake, surrounded by factories. It took our much time to get the permission to enter. Suprisingly, we obtained a set of salt samples from one of the factories and learned the process of manufacturing salt in the modern society. Ebinur Lake was almost dried even if Jing River （精河） and Bortala river （博尔塔拉河）both flow into it. Under the circumstances, Jiao and Zhicheng walk into the middle of the lake with rubber shoes.

We spent our last day on collecting surface water samples at Sayram Lake, which was known as “The last tear of the Atlantic”. Sayram Lake was so attractive that it was more like a sightseeing than sampling site for us. However, we still take it seriously.

During the entire sampling campaign, the joy was far more than the hardship and we four reviewed every day to make sure the selected sampling sites were  worthwhile. Also, our Russian proficiency enhanced greatly thanks to Prof. Gan.  LOL. I hope the follow-up experiment would go well and make dreams become reality.

Dong’ao Island workshop

On July the 10-11th, Shizhen, Jun and Gan joined a joint workshop between SYS-U, Institute of Tropical Forestry (ITF，热林所) and GIG. We also investigated potential air sampling sites on the small Dong’ao island（东澳岛）. It takes about 40 minutes to ferry from Zhuhai to the island. The trip was organized by Professor Chen Jianyao（陈建耀） of SYS-U and his team. Professors Zou Shichun （邹世春）of SYS-U, Zhou Guangyi （周光益）and Wang Xu （王旭）of ITF participated the event. Gan gave a talk on radiocarbon applications in delineating carbon dynamics on the Earth’s surface. It was extremely hot with strong sunshine. However, we quite a lot enjoyed the beautiful island scenery as guided by local government officers， especially being looked after by Dr Zhao Xinfeng（赵新锋）of Zhuhai Environmental Monitoring Centre.  Per embankment Zhuhai, we had chance to enjoy a big feast prepared by Haoyu, with all group members of Professor Zou Shichun’s group in SYS-U. A nice trip!
