2. 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

3. Example of Innovation (Coastal Eutrophication)
Atmospheric CO2
Combination
Sea weed aquaculture
Biofuel production
CCS
Reduce

4. 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
