For effective restoration of enclosed coastal zone under anoxic environment such as Osaka bay, it is necessary to understand characteristics of oxygen consumption by the bottom sediment of ports and harbors. In this study, field measurements of the oxygen consumption rate were carried out during the year in a harbor. Seasonal variations in characteristics of the oxygen consumption by sediment were presented and the formulation of oxygen consumption by bottom sediment was attempted.
