| Outline of Final Research Achievements |
It is important to grasp the contribution of primary producers in carbon dynamics to utilize the blue carbon function in urban coastal areas. The purpose of this study was to clarify the CO2 balance between air and the intertidal flat or sea, and to estimate the contribution of phytoplankton in the carbon dynamics of an artificial tidal flat constructed in urban coastal zone.
The observation data of air-sea and air-intertidal flat CO2 fluxes suggested that the tidal flat played as a CO2 sink in all season and the effects was greatly affected by benthic microalgae. On the other hand, the contribution of phytoplankton in carbon dynamics in seawater was estimated to be about 10 to 30%.
