Reviving the fishing industry in the Tohoku region by remotely sending data to create a map displaying reconstruction support and damage to seaweed bed

Research grant

Project Description

Seaweed beds are an important foundation of coastal fisheries in the Tohoku region, but little has been done to address and understand the serious damage was caused by the Great Eastern Japan earthquake and tsunami. Our aim is to aid the recovery of the fishing industry on the Tohoku coastline and support the regeneration of seaweed beds in afflicted areas. To do this, our research will use remote sensing technology to grasp the scale of the seabed situation, and in addition to grasping the damage caused in the afflicted areas, share the information necessary for restoration and recovery with local constituent groups.
