PACMANUS 和 DESMOS 的高分辨率的地形学测量用在手的 ROV 的热水的地盆

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.The DESMOS
