内容記述（抄録等）
The gmundwater in Daikonjima island in Shimane prefecture，southwest Japan were investigated for salinity and temperature using the long-term observation system“CT-sensor”．Tritium concentrations of the groundwater supported the interpretation of the freshwater-lens behavior．Bottom fluctuation of the freshwater-lens was compared with tidal variation in Lake Nakaumi．Tidal effect was recognized in the intermediate zone below the freshwater-lens and above the high saline water．High tritium concentrations in the intermediate zone suggest the advection of new saline water from Lake Nakaumi．
