There are mineral-rich hydrothermal deposits around of the seabed in Japanese exclusive economic zone (EEZ). For securing of mineral resources in Japan, a precise investigation and estimation technique is highly emphasized.<br> Our group has studied a new exploration technique to evaluate the distribution of underwater layer structures of the hydrothermal deposits using “Mils-Cross” method with a low-frequency acoustic source deployed into the autonomous underwater vehicle (AUV) which is running at a low-altitude near the sea bottom.<br> In last researches, our group developed a prototype low-frequency acoustic source, and confirmed that this source is useful to acquire the sub-bottom profiling data under the bottom of Hitachi-Tone river by executing a performance test. <br> Based on these results, we developed a prototype deep-water acoustic exploration system to find out the layered structures under the actual hydrothermal deposits.<br> We deployed our prototype system into the deep-water exploration towed body “Deep-Tow” that is installed into the research vessel “Natsushima, ” and implemented a cruising test to acquire the actual acoustic data under the hydrothermal deposits in the East-China Sea. <br> After some analysis using these data, we confirmed that our prototype system can acquire the layered structures under of the sea-bottom and sub-bottom profiling data around the hydrothermal deposits.[This abstract is not included in the PDF]<br>
