Overview
Topographic survey will be carried out at the blank area by the SEABEAM2112 loaded on the R/V Kaiyo. ROV Hyper-Dolphin will dive off Sanriku for estimating the mass of debris, biomass of commercial species and other animals using by the stereo digital camera system, analyzing behavior and distribution pattern by the bio-tracking system, elucidating the fishery environmental dynamics by the long term monitoring system, and clarifying dissolve process of debris by collecting samples.
