On the afternoon of July 9, China’s ocean scientific survey ship, Xiangyanghong 10, completed her 43rd ocean expedition and sailed back to Zhoushan. Two professors (Prof. Han Xiqiu, Prof. He Zhiguo) and one Ph.D. candidate (Zhu Rui)of the Ocean College, Zhejiang University participated in the fifth leg of this expedition. It took approximately 50 days and was primarily focused on a scientific survey on polymetallic sulfide in the Carlsberg Ridge in the northwestern Indian Ocean. During this survey, scientists obtained rich mineral samples and collected a diversity of biological samples.

“Our major task is to conduct research into the structural features of underwater hydrothermal plumes by means of exploration and data analyses, thereby helping pinpoint the location of hydrothermal vents more accurately and improve the simulated model of hydrothermal plumes. Although it involves a lot of hard work and unpredictable risks, it is of immense help to identify scientific issues in a more rational and profound manner,” said He Zhiguo.
