Abstract: The Ariake Sea is a semi-closed bay surrounded by four prefectures of Kyushu Island in Japan. The sea water is exchanged with open sea almost through the Hayasaki Straight. An outermost part, a central part and an innermost part of the bay have different characteristics individually and suitable creatures exist in each area. Recently, it has been much reported that the environment of this bay has been suddenly changed. Monitoring the environment of the large bay for a long time requires much time and cost. Therefore, a satellite remote sensing can be considered as an effective solution to monitor a wide bay area. In this paper, the method to monitor the water quality of the Ariake Sea by TERRA-ASTER sensor is studied and its potential is confirmed.
