Fig. 9.14 Fate of eelgrass-derived organic carbon that flowed out of the eelgrass bed to the sea
area (results of the model simulation). Above: seasonal variations of eelgrass-derived carbon
amount in the Seto Inland Sea. Below: (upper) distribution of leaves floating and settling in the sea
area; (middle) distribution of particulate organic carbon in sea water; (lower) distribution of
organic carbon settled on the sea bottom
Fig. 9.15 Mass balance of the eelgrass-derived carbon in the entire Seto Inland Sea: (a) proportions of the total carbon discharged from the eelgrass bed, and (b) proportions of eelgrass-derived
carbon at the end of the calculation. POC, particulate organic carbon; DIC, dissolved inorganic
carbon; DOC, dissolved organic carbon
