Xiaofei’s new paper accepted by ES&T

Xiaofei’s new paper entitled ‘ Provenance of Aerosol Black Carbon over Northeast Indian Ocean and South China Sea and Implications for Oceanic BC Cycling‘ has been accepted for publication in ES&T; and was chosen as a supplementary cover story of the issue. Congratulations!

Image chosen for a supplementary cover story of the ES&T issue. The little Asian elephant was added as an element to represent the South and Southeast Asia, where the studied area was.

Figure 4. Source fractions (pie chart) and air mass back trajectories (colored lines) of aerosol black carbon (BC) in the dual-carbon isotope province of “SCS close to Chinese Mainland” (gray), “Open SCS” (green), “NEIO close to Southeast Asia” (blue), “Open NEIO” (light purple), “Malacca Strait” (pink) and “Sunda Strait” (orange). Air mass back trajectories in an isotope province share the same color. (SCS: the South China Sea; NEIO: the northeast Indian Ocean)

“Wind-in-his-hair” Ssampling Campaign at Heshan in Preparation

On July 17th, a small group of Shizhen, Engineer Li, Linbo, Lele, Jianchu and Weiru went to the Heshan air monitoring supersite, to maintain air sampling machines on the rooftop of the station building as well as supply 40 sets of sampling materials for summer sampling campaign. Despite of the heavy rain, we five struggled in the rain to protect Engineer Li and the machines.Finally,  all the  machines were complished flow correction. We look forward to the approaching  sampling campaign.

Well-packaged sampling materials.

Professional Engineer Li was maintaining air sampling machines.

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!
