INVESTIGATIONS OF WATER QUALITY FLUCTUATION OF THE INNERMOST PART OF THE ARIAKE SEA BY FIELD OBSERVATION

Abstract

The Ariake Project II was operated in July 2003 to grasp the whole features of water movement and water quality change in the Ariake Sea. This study reports the results obtained from a part of the project. Especially, the features at an innermost part of the Ariake Sea are described in detail. Observation along vertical measure lines at fixed points and a long-term observation at observation tower are combined to consider the mechanism of water movement and water quality fluctuation. As a result, the project can be effective to study the summer feature of the Ariake Sea with meteorological conditions, such as rain, wind, and other watershed conditions.
