This paper describes contribution of strong wind events on Dissolved oxygen (DO) concentrations in Tokyo Bay by statistical analysis. Tokyo Bay is a typical enclosed bay in Japan whose water quality has been deteriorated. For example, the occurrence of anoxic water in the bay head adjacent to the seabed is frequent. Since estuarine circulation dominates DO concentration and a strong wind event is revealed to enhance recovering processes of DO concentration, this study aims to understand

As a result, pdf analysis has potential in the evaluation of the recovery processes of DO concentration around the head of Tokyo Bay. Strong wind events were also revealed to appear from May to August dominantly.
