Abstract: A recent measurement result of mercury distribution by Tomiyasu et al. (2000) has shown mercury transport from Minamata Bay into Yatsushiro Sea. In order to elucidate the tidal current characteristic in Minamata Bay, a long-term simultaneous measurement on tidal current velocity and turbidity was executed during not only winter season in 2004 but also summer season in 2005. Furthermore, to understand the water quality dynamics, water temperature, salinity and the Dissolved Oxygen were regularly measured. As a result, the tidal current characteristic and the seasonal change of the water quality in Minamata Bay were realized.
