| Outline of Final Research Achievements |
The second CO2 problem; ocean acidification will have various effects on marine ecosystems. If biological pump which is a carbon sequestration mechanism is affected, feedback to progress of ocean acidification is expected. Therefore, we carried out mesocosm experiments which is closed vessel with large volume with manipulation of pH. As a result, production of sinking particles wouold decrease due to ocean acidification, and the mechanism would be a shift of phytoplankton community structure into a dominance of small-sized microalgae. The decrease in the production of sinking particles will result in acceleration of ocean acidification.
