Recently, hydrothermal deposits below the seafloor are believed to be useful for human activity. Because the size of each deposit is much smaller than that of an offshore oil field, detailed exploration for the position and the estimated mass is need

3D Acoustic imagery generation by interferometric analysis of long baseline using Interferometric Real Aperture Sonar

Autor: Aritoshi Mio, Fuyuki Katase, Satoshi Tsukioka, Akira Asada, Tamaki Ura, Shinobu Omika, Katsunori Mizuno, Mitsuhiro Kojima

Publikováno v: OCEANS 2015 - MTS/IEEE Washington.

We are developing a technique for the systematical exploration of submarine hydrothermal ore deposits. In the Izu-Ogasawara Arc area these deposits are usually characterized by the existence of tower-like vents 2∼20m high by 2∼5m wide. We are usi

Publikováno v: OCEANS 2015 - Genova.

It is known that there are mineral deposits below seafloor. Gravity survey is one of powerful methods for exploration of underground deposits. A new system is needed to survey a wide area quickly with a higher resolution. Recent technology of an auto

Conceptual Design of Navigation of an AUV for Monitoring CCS Site at Deep Sea Bottom

Autor: Yoshitaka Watanabe, Tadahiro Hyakudome, Shojiro Ishibashi, Shinobu Omika, Yoshiyuki Nakano, Hiroshi Ochi, Masami Matsuura, Hiroshi Yoshida

Publikováno v: Volume 5: Ocean Space Utilization; Ocean Renewable Energy.

We, Japan Agency for Marine-Earth Science and Technology (JAMSTEC), are developing an autonomous underwater vehicle (AUV) whose main mission is monitoring a site at the sea bottom for the carbon dioxide capture and storage (CCS). The AUV cruises very

Surface and Domain Structure of Pure PbTiO3, Mn-doped PbTiO3 and Pb(Zn1/2Nb1/2)0.91Ti0.09O3 Single Crystals by Atomic Force Microscopy

Autor: Kenrou Kawano, Shinobu Omika, Takashi Yamamoto, Mitsuru Saito

Publikováno v: Japanese Journal of Applied Physics. 36:6145

Nanometer scale surface morphologies in pure PbTiO3, Mn-doped PbTiO3 and Pb(Zn1/2Nb1/2)0.91Ti0.09O3 single crystals prepared by the flux method have been investigated by atomic force microscopy and discussed in connection with 90° and 180° domains.
