説明

We have been working on survey system by AUV troop to extend survey efficiency during one cruise. This paper reports about dive survey system for AUV troop and observation results by hovelling type AUV "Tuna-Sand" in KY12-13 research cruise that Izu-Ogasawara ocean area was observed on October 2012. "Tuna-Sand" dived three times and total diving time is over six hours in the cruise. "Tuna-Sand" took over 170 pictures of Smith caldron see floor in first dive. "Tuna-Sand" navigated along serpentine course during observation, because periodic current in sea floor is strong for "Tuna-Sand". Diver survey by 3 AUVs include "Tuna-Sand" was success in second, but "Tuna-Sand" had CPU problems and emergency surfaced. In third, "Tuna-Sand" could not observe for lack of time.
