Overview
To investigate the distribution of Tsunami debris and seafloor geological enviroment we carry out an acoustic survey using a sice scan sonar and sub-bottom profiler off northern area of Miyagi prefecture and Otsuti area. We also launch the establishment of the Lander for monitoring environmental data off Otsuti area.
