Abstract

<p>It says that the mineral resource exists richly on the bottom of the sea in EEZ in vast Japan, about 4.48 million km2, but there are many problem which it should conquer in the resource-searching in the deep sea and doesn't reach to grasp correct abundance.</p><p>Asada laboratory (Institute of Industrial Science, the University of Tokyo), it is promoting the development, the coming to practical use of the prospecting technology to grasp more efficiently as “the ocean mineral resource wide area prospecting system”than 2013 and effectively and technology transfer business to the private enterprise and so on.</p><p>In this clause, among the ocean mineral resource wide area prospecting system, it introduces the basic performance of AUV built-in type IsSAS which was developed to investigate a hydrothermal deposit and so on efficiently and effectively by the high-precision 3D sound image and a measurement case.</p>
