Abstract

Field surveys and indoor experiments were conducted at the north tidal flat of Osaka Nanko bird sanctuary in 2012 in order to measure the amount of discharge of the carbon dioxide (CO₂) which is an index of the amount of organic matter decomposition. The field survey revealed that CO₂ flux increased with decrease of the groundwater level when the bottom sediment emerged. The CO₂ flux in the submerged period showed 0.2-1.2 mgCO₂/m²/min which was less than 1/5 to 1/40 of the emerged period. In addition, the result of field surveys together with indoor experiments suggested that CO₂ flux changed depending on the flood tide or falling tide as well as the groundwater level.
