Abstract

Emissions of CO₂ from tidal-flat sediments were measured using the chamber method to investigate the characteristic of organic matter degradation at the north pond of Osaka Nanko Bird sanctuary. Indoor experiments were also conducted to clarify the effect of changes of the groundwater level on the CO₂ emission by manipulating the water table level of the sediment. The amount of organic matter degradation varied seasonally and increased with increase of temperature and biomass of benthic organisms in summer. Emissions of CO₂ from the bottom sediment were highest when the water table level was lowest at low tide in a day. These results demonstrate that the amount of organic matter degradation varies daily or seasonally depending on temperature, groundwater level and biomass of organisms of the bottom sediment.
