Tsinghua University's deep-sea controllable visual sampler (DCVS) completes East China Sea hydrothermal and cold seep voyage operations

The East China Sea voyage organized by Tsinghua University in collaboration with the Qingdao Institute of Marine Geology has returned successfully. Using the independently developed deep-sea controllable visual sampler (DCVS), the team completed dive operations at 7 stations in areas including the Xianchi cold seep area and the Qiaoyue hydrothermal field, with a maximum dive depth of 1260 meters. DCVS operated stably under extreme conditions such as high temperature and high pressure, collecting multiple physical samples and acquiring large amounts of high-definition seabed imagery. The equipment was developed under the leadership of the Department of Automation at Tsinghua University, with participation from Shanghai Jiao Tong University and Xiamen University.
