Outline of Final Research Achievements

An observation of the tide is an effective method to investigate environments of the sea. We can know speeds and direction of tide to measure a position of drifting objects floated on the water. The drifting small buoy system with various sensors and a GPS receiver has been developed for a purpose of observing the tide of an inland sea. We explained the result observed the tide current of Yatsushiro Sea using the buoy system. The densities of fresh water and salt water differ near the mouth of a river. The flow velocity of a shallow point and a deep point differ. Thus, for observation of all range depth, we made a float which can adjust own buoyancy. The float can keep the optical depth. We utilize the float, and we can know the tidal current at hoping depth in the sea.
