| Research Abstract |
Observation records by 24 Shinkai 6500 dives of 3 R/V Yokosuka cruises and analyses on collected samples elucidate the followings ;(1) Tectonic process of Godzilla mega-mullion, which is the world largest Ocean Core Complex(OCC) in the Parece Vela Basin was investigated, and(2) A serpentinite-hosted new ecosystem consisting of principally Calyptogena clams was discovered at near Moho in the Southern Mariana Forearc. Young volcanic field at rifting stage was also found in those eastern area.
