Magnetostratigraphy of hydrogenetic manganese crusts from Northwestern Pacific seamounts

Autor: M Joshima, A Usui

Publikováno v: Marine Geology. 146:53-62

Fine-scale dating is crucial to understanding the growth and environments of formation of marine manganese deposits. The paleomagnetic method of dating of manganese nodules and crusts has been attempted but with no success so far. We measured remanen

Sea Floor Mapping using the Data of Forward Looking Sonar and Side-Scan Sonar around the Hydrothermal Sites, South Mariana Trough

Autor: K. Kisimoto, K. Nishimura, M. Joshima

Publikováno v: 2007 Symposium on Underwater Technology and Workshop on Scientific Use of Submarine Cables and Related Technologies.

Processed data of the mesotech 971 forward looking sonar was successfully plotted on a map and compared with side-scan-sonar (SSS) data and color image of original forward sea floor record. The accuracy of positions by LBL acoustic system is insuffic

Since 1987, Japanese and French geologists, geophysicists, and biologists have been studying the North Fiji Basin Ridge within the framework of a joint project named STARMER (Science and Technology Agency of Japan—IFREMER of France). This ridge was

Bathymetry and Canyons of the western Solomon Sea

Autor: J. B. Keene, K. Hashimoto, M. Joshima, J. E. Stuart, D. L. Tiffin, Hugh L Davies

Publikováno v: Geo-Marine Letters. 6:181-191

The floor of the western Solomon Sea (for new bathymetric map see inside back cover of this issue) is dominated by the arched and ridged basement of the Solomon Sea Basin, the partly-sediment-filled New Britain Trench, and a more completely filled tr

Off-Line Deep-Towed Seismic Profiler

Autor: F. Murakami, T. Miyazaki, K. Kisimoto, T. Ishihara, M. Joshima, K. Nishimura

Publikováno v: Exploration Geophysics. 19:299-301

A deep-towed seismic profiling system is being developed to obtain detailed subbottom structures in deep seas around island arcs like Japan. Features of the system are as follows: (1) Off-line towing: both a hydrophone streamer and a recording unit w
