Enclosed coastal seas are suffering from serious environmental problems which caused by hypoxic condition occurring at the bottom of sea during summer season. Although many restoration technologies for supplying oxygen to the bottom of the sea are developed, it is necessary to understand the characteristics of sediment oxygen consumption (SOC) before applying these technologies in actual field because it is thought that the sediment oxygen demand increases under hypoxic condition. In this study, we carried out the field investigations for a year at Osaka bay by using a new chamber method which can measure SOC under hypoxic condition in order to examine the seasonal variations of SOC. In addition we conducted the laboratory experiment for examining the effects of biological and chemical factor on the SOC.
