An ocean-going autonomous underwater vehicle equipped with detailed-mapping acoustic instruments and a high-resolution underwater gravity measurement system was completed by Japan Agency for Marine-Earth Science and Technology. The instruments composed a multibeam echo sounder, a sidescan sonar and a subbottom profiler are synchronized their pings including DVL to prevent acoustical interferences. An underwater precise gravity measurements system uses for exploration of seafloor mineral deposits, mounted on a gimbal mechanism in a pressure housing with communication between the AUV that developed by the university of Tokyo, Earthquake Research Institute. This paper presents operational engineering for the systems, and results around hydrothermal area.
