Abstract
Omura Bay in Nagasaki Prefecture, which is connected with the open sea through Sasebo Bay, is called a double-closed bay. It is also an obstacle for a tidal current of Omura Bay that there are very narrow channels between these bays. Satellite remote sensing technique was applied to the visualization of the seawater plume in Omura Bay. The plumes show the current from surface to the depth of a few meters, as Landsat5/TM data have relation to the seawater quality in the same area. The plumes were investigated with the tide of the bay. It follows that the direction of incoming seawater is the same as the topographical direction of Hario Channel, and that there is a tidal residual current between Hario Channel and Ohsaki Peninsula. Lastly the observation by using current meters was also shown to back up these movements of the plumes.
