Abstract

<p> “Blue carbon”, which is carbon fixed by marine organisms, is attracting attention as a new measure to reduce atmospheric CO2. We carried out field survey regarding the CO2 partial pressure (pCO2) in sea water in the Yatsushiro Sea where it is confirmed that habitats of corals and seagrass, in order to reveal the pCO2 dynamics in actual situation. Moreover, by observation under different mixing conditions, we tried to reveal how stratification can affect on the dynamics. As a result, it was confirmed that with the development of strong stratification, the effect of photosynthesis by phytoplankton was concentrated on the surface and pCO2 decreased. In addition, it was suggested that the influx of water affected by corals caused the fluctuation of pCO2. Finally, trial calculation of CO2 flux between sea and air in daytime shows that the Yatshiro Sea can absorb CO2 throughout the year, regardless of the mixing conditions.</p>
