Need of Multidisciplinary Mitigations to Save Ocean Environment Yoshihisa Shirayama Japan Agency for Marine Earth Science and Technology And Ocean Policy Research Institute, Sasakawa Peace Foundation

Status Global Ocean Climate Change is real Distribution of Japanese reef-building corals expands toward North Even rise of deep-sea water temperature has been observed in the Southern Ocean Ocean Acidification starts to impact marine plankton Thinning of Pteropod shells has been observed in the Arctic Ocean Mitigation of CO2 emission is not enough

Example of Innovation (Coastal Eutrophication) Atmospheric CO2 Combination Sea weed aquaculture Biofuel production CCS Reduce Atmospheric CO2 Nutrients Sea weed Aquaculture Blue Carbon Biofuel Electricity　Generation CCS

How to implement? Many other possibilities Marine Plastic Debris ++ Deep-sea Mining ++ Dialogue among multidisciplinary stakeholders Increase of opportunity Business chance of Networking and Innovation
