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!
