摘　　要：In China,the lack of high-resolution topographical data from small target areas limits our understanding of deep sea phenomena.Here,the high-resolution topography of the PACMANUS hydrothermal field and the DESMOS hydrothermal field were measured using a remotely operated underwater vehicle(ROV)with a multibeam system.A composition positioning system on the ROV provided high positioning accuracy(greater than 0.5 m).The data show that four knolls develop in the PACMANUS field on the crest of the Pual ridge.TheIn China, the lack of high-resolution topographical data from small target areas limits our understanding of deep sea phenomena. Here, the high-resolution topography of the PACMANUS hydrothermal field and the DESMOS hydrothermal field were measured using a remotely operated underwater vehicle （ROV） with a multibeam system. A composition positioning system on the ROV provided high positioning accuracy （greater than 0.5 m）. The data show that four knolls develop in the PACMA- NUS field on the crest of the Pual ridge. The DESMOS caldera is approximately 250 m deep in the center with an E-W diameter of approximately 1 km and an N-S diameter of approximately 2 km. This survey is the first trial in China using ROV data to measure the deep-sea high-resolution topography of small-scale target areas. Validation of the survey method proved it to be applica- ble, which will promote the development of deep sea research in China.
