On April 21, Zhai Wanying and TongJianfeng, both teachers sent by SHOU to the 34thAntarctic Expedition of China, satisfactorily accomplished their expeditiontasks, and successfully returned to Shanghai by the “Snow Dragon”. They were on theexpedition to undertake the NSFC International Cooperation and Exchange Projectentitled “Study on the Evolution of Fish Immunology in Extreme Environments”led by professor Chen Liangbiao and the NSFC Outstanding Youth Fund Project“Broadband Ultrasonic Scattering Characteristics and Resource Estimation ofEuphausua Superba” led by Doctor Tong Jianfeng. In addition, Zhai Wanying participatedin the whole-voyage survey of the ocean team of this expedition; Tong Jianfengtook part in the survey of the marine reserve site selection team on theAmundsen Sea. This expedition lasted for 165 days and a total voyage distanceof more than 38,000 sea miles, and passed by Christchurch in New Zealand, theRoss Sea, the Zhongshan Station, the McMurdo Station and the Amundsen Sea.


In this Antarctic expedition, Zhai Wanyingwas mainly responsible for collecting Antarctic fish and water environmentsamples, and ultimately collected a total of 30 water environment samples and60 Antarctic fish samples from the new station on the Ross Sea, the ZhongshanStation and the McMurdo Station, including Chionodracohamatus,Gymnodracoacuticeps, Trematomusbernacchii and many Trematomus species.According to the research needs of the project, Zhai Wanying performed shapemeasurement, blood drawing, dissection and tissue preservation for the samples,conducted meg-base DNA extraction, and provided short-term taming and breedingand pre-treatment under existing conditions. His sample collection work offeredideal experimental materials and early preparations for investigating theadaptation and evolution of fish in extreme environments, and laid a solidbasis for follow-up studies.Tong Jianfeng obtained a total of 214GBbroadband ultrasonic echo scattering data on 14 stations with the broadbandacoustic measurement system independently developed by SHOU; at 37 stations onthe Amundsen Sea, he used the scientific fish finder system EK60 on the “SnowDragon” to conduct biological scattering layer observation, and offeredassistance in EK60 system correction. During the voyage on the “Snow Dragon”,he also presented an exchange report, entitled “Application of the AcousticApproach in Marine Ecosystem Observation”.
