Abstract

To understand oxygen consumption characteristics of sediment for the case of oxygen supply to the bottom of sea under the hypoxic condition, we carried out a laboratory experiment by using sediment and artificial-seawater. It is found that the oxygen consumption pattern of sediment is changing while sediment consumes oxygen. Immediately after oxygen supplying, dissolved oxygen of seawater was consumed by the chemical reaction in the sediment. And then dissolved oxygen consumed by the biological reaction.
