Research Abstract

The project leader found that the salinity stratification is formed over the whole region of Isahaya Bay in the rainy season and that the salinity in the deep region of Isahaya Bay decreases to about half value of ordinary sea water in some cases and it recovers in some cases. This project was made under the hypothesis that the salinity stratification might be due to the discharge from the rivers running into Ariake Sea and its appearance and disappearance might be generated by local wind in Isahaya Bay. The obtained results are as follows: 1)The salinity stratification over the whole region of Isahaya Bay is mainly due to the discharge from Chikugo River. 2)The north-northeasterly wind transports the water mass of low density near the water surface from Ariake Sea to Isahaya Bay.3)The south-southwesterly wind tends to suppress the inflow of the water mass of low density from Ariake Sea to Isahaya Bay and to promote conversely its outflow from Isahaya Bay toAriake Sea.
