A successful trip to Sri Lanka in October 2017

Dilanka, Liu Xin, Zhao Shizhen, and Zhong Guangcai had a trip to Sri Lanka from Oct. 22-30, 2017. We met our old friends from University of Ruhuna in Matara and new friends from University of Peradeniya in Kandy. We established collaboration on passive air sampling, mussel sampling, and sewage plant water sampling for a Southern Contaminants Programme (SCP), which is based on international collaboration and funded by Chinese Academy of Sciences (CAS) as part of its Belt & Road Initiatives. We discussed further cooperation in other aspects in the future.

A welcome dinner  with friends from University of Ruhuna (UoR). Left to right: Zhong Guangcai, Dilanka, Pro. Tilak, Zhao Shizhen, Liu Xin, Dr. Upul.

Discussion with Dr. Upul on passive air sampling (PAS) and mussel sampling.

Shizhen was demonstrating the PAS. Left to right: Jonathan and Sangeeth, from the Faculty of Fisheries and Marine Sciences & Technology, UoR.

Deployed PAS in the UoR campus with the help from two excellent students (Jonathan and Ayoma) and technical officer (Samantha).

Liu Xin was demonstrating packing of mussel samples.

Jonathan and Ayoma were taking mussels at Matara seashore.

Discussion with Pro. Shameen (Faculty of Engineering, University of Peradeniya) on PAS in Kandy.

Pro. Karu  (Faculty of Engineering, University of Peradeniya)  showed us his excellent and interesting studies on air pollution. We discussed on future cooperation.

Done PAS in Kandy with the great support by Rajitha (left) and Tharindu (right) from Faculty of Engineering, University of Peradeniya.

Done PAS in Colombo with kindly help provided by local friends.

Dilanka did field investigation of a sewage plant in Colombo.

The ladies celebrated this successful trip with a nice dinner.

Zhong Guangcai’s first cruise to open sea: central basin of South China Sea

             I was excited to have my first cruise to open sea. That’s one more milestone of my life. The cruise   started from Xinzhou Wharf (新洲码头) of Guangzhou on 29 March, carrying out by Chinese research vessel Shiyan 1. I spent 39 days over the South China Sea with only one-day stop at Sanya. Most sampling took place at the central basin of South China Sea, whose max depth is >4000m. Weather at the South China Sea was quite nice in this season, or we were always able to escape before strong waves were generated. Additionally, rooms of Shiyan 1 are comfortable.

              I took sediment core samples with both gravity sampler and box sampler. Sediment sampling was team work. There were 7 persons in the sediment sampling team, who were from South China Sea Institute of Oceanology (SCSIO) and Guangzhou Institute of Geochemistry (GIG), CAS.

Photo 5: Took surface sediment and sediment cores with box sampler. The box size is 30cm*30cm*70cm. Weight of the sampler is ~250kg.

Besides sediment sampling, I also took surface seawater with metal sampler and took deep seawater with CTD.
