Jingkai GUO, an undergraduate student from the Department of Ocean Science and Engineering at the Southern University of Science and Technology (SUSTech), joined the TS-51-3 scientific expedition on the “Tansuo-1” research vessel. He also took a ride on China’s independently developed manned submersible “Shen-Hai-Yong-Shi” (Deep Sea Warrior) and completed a 3,900-meter deep dive.

As a member of the expedition, Jingkai GUO participated in the comprehensive marine survey, undertaking tasks such as CTD water sampling, water quality parameter measurement, sediment core sub-sampling, and sample recording. During several days of continuous work at sea, he gained a deep understanding of the deep-sea scientific survey process, systematically learned methods for sample collection, on-site processing, and research documentation, and enhanced his professional practical skills in a real research environment. 

“This was an incredibly memorable and valuable research experience,” said Jingkai GUO. Taking part in the “Tansuo-1” expedition and participating in deep-diving operations allowed him to more directly feel the close connection between marine science research and the country’s marine strategic needs, further strengthening his determination to pursue a future in marine science research. 

This undergraduate participation in a national deep-sea scientific expedition is just one example of SUSTech’s Department of Ocean Science and Engineering’s commitment to combining practical education with research-based learning. The department has continuously relied on high-level research platforms and major scientific tasks to encourage students to step into labs and head out to the ocean, enhancing their innovation skills and professional competence through hands-on research practice.
