SIP 2nd Term
2018-2022 |
- Rare Earth Approximate Resource Assessment Completed
- Detailed investigation of the rare earth strata in Minamitori Island was conducted, and the approximate resource assessment was completed.
- Successful Autonomous Underwater Vehicle (AUV) Fleet Control Test with 4 Units
- Successful acquisition of seabed topography data using a fleet of 4 different AUVs controlled in formation.
- Development of a world-leading survey system to improve the efficiency of deep-sea resource exploration (AUV fleet control technology, multi-user acoustic communication capability, long-term wide-area marine environment monitoring) was conducted.
- Successful Mud Lifting Test using the Deep Earth Exploration Vessel "Chikyu"
- Developed technology to enable rare earth mud mining in deep-sea sediment, conducted real-sea trials at a depth of 2,470m, and successfully lifted seabed sediment for the first time in the world.
- Contributed to the promotion of ocean CCS in Japan.
- Completion of Long-term Environmental Monitoring in Minamitori Island and Issuance of 4 ISO Standards
- Completed long-term environmental baseline survey in the offshore area of Minamitori Island.
