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

2023-11-20 Weiru Wang

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

2023-07-17 Gan Zhang

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!

A Sri Lanka update

2023-07-02 Gan Zhang

On June 25th-July 2nd, the team of four, Shizhen, Jun, Guangcai and Gan, restarted international travels after the long-lasting COVID-19. We first visited Sri Lanka to promote our ANSO MOROTOXA program. We left via Shanghai therefore we were able to pay a short visit to Lin Tian (林田、赵祯）et al. at Shanghai Ocean University where we also met Yingjun (陈颖军） and Prof Guo Zhigang （郭志刚）of Fudan University who joined thegathering. We arrived at Colombo in the evening of June the 26th, returned to Kunming on July 2 morning. In Kandy, We met Professor Karu and his colleagues with great pleasure; and visited the Postgraduate Institute of Sciences (PGIS) and the Sino-Sri Lankan Joint Centre for Research and Education at Peradeniya University. Shizhen and Jun demonstrated setting up the active sampler. Gan delivered presentations on the CKDu water tank sediment core study results, which attracted great attention, and the background of our ANSO MORATOXA program, of which Peradeniya University has been a partner. We had chance of cause to visit at the weekend several historic and natural attractions of Sri Lanka; and celebrated cheerfully at Trincomalee Shizhen’s birthday. A wonderful trip!
