Current Research

I have studied electrical conductivity structure of the Earth\'s interior, especially for oceanic upper mantle, based on natural electromagnetic variations observed by seafloor instruments, to discuss the mantle dynamics. The study area contains various tectonic environments, such as plate boundaries (mid-ocean ridges, trenches), hotspots, normal basins. Development and improvement of the instrumetns and data analysis methods are also the subjects of my study. Many studies have been conducted via domestic and international collaborations.
