Research Abstract

The strong water temperature front moved northward and approaches near the Satamisaki when the peak of inflow transport. We found that the dominant variation of the inflow transport equivalent to temperature front is approach and inrush into the bay.
Inflow volume transport by the events average velues were 16.2^<**>10^8m^3 /day and other inflow average values were about 7.7^<**>10^8m^3 /day. Furthermore the large inflow transport corresponded to the strong northward velocity in the eastern upper layr.
The flow pattern in winter accounted for 57% of the inflow in the upper layr and the outflow in the lower layr. However, in summer acounted for 53% of the outflow in the upper layr and the inflow in the lower layr.
We installed a temperature sensor on board a ferry voyages between Tarumizu-Kamoike, Yamakawa-Nejime, and Just began to measurement sea-surface temperature by record interval of one minute.
