II.Formation of Shatsky Rise, Mesozoic oceanic plateau

I revealed tectonic history of the Pacific Plate just before the formation of the Mesozoic Pacific oceanic plateau, Shatsky Rise.

IV.Bending-related topographic structures
of the subducting plate in the northwestern
Pacific Ocean

I investigated elongated topographic structures associated with bending of the subducting oceanic plate along the western Kuril, Japan and northern Izu-Ogasawara trenches, using available multibeam bathymetric data.

V. Bathyemtric features of the world's deepest seafloor, Challenger Deep

I made a precise bathymetric map of the world's deepest seafloor, Challenger Deep in the Mariana Trench.
