Abstract
<p> In present study, the effect of the seasonal difference in photosynthetic activity of eelgrass on the absorption/release characteristics of dissolved inorganic carbon was clarified from the results of model analysis of changes in dissolved inorganic carbon by aquatic tank experiments using eelgrass and chlorophyll-a content analysis. It was revealed that the optimum value of the maximum photosynthetic rate for dissolved inorganic carbon by eelgrass varies depending on the season of the experiment. From the estimated values by the model and the results of the chlorophyll-a content of eelgrass, it was suggested that the difference in the growth stage of eelgrass affected the photosynthetic activity and the maximum photosynthetic rate. The results obtained based on the measured values of the detailed specifications of eelgrass were applied to the model to clarify the relationship between the characteristics of the vertical profile of dissolved inorganic carbon and the branching structure of eelgrass.</p>
