| Outline of Final Research Achievements |
In order to clarify how ocean carbon cycle changes spatiotemporally, we developed the analytical technique for ocean carbon species (alkalinity, dissolved inorganic carbon, pH) along with making parameterization of ocean carbon species in the North Pacific.
Applying our parameterization to high precision hydrographic data set, we had the detailed spatiotemporal distributions of ocean carbon species in the North Pacific. Additionally, we found out the long-term trend of anthropogenic ocean acidification with -0.002 pH/year over the entire ocean.
