Abstract
The sea area around Ieodo is analyzed from the CTD data and the S-ADCP data observed in 23 Aug. 2016. Ieodo, an underwater reef, is located 149 km southwest of Marado in Republic of Korea. It has 4 peaks and is about 4.6 meter below sea level. It stretches about 600m north to south and 750m east to west from its top. It has the same geographical characteristics as the seamount.In the sea area around Ieodo, the northward flow appeared during the ebb tide, the southward flow appeared during the flood tide. The strong stratification formed in summer seems to change the depth depending on the sea water current. The thermocline depth becomes deeper at the north of the Ieodo when the northward current flows and theupwelling flow occurs. And the thermocline depth becomes shallower at the south when the southward current flows and the downwelling flow occurs. In this way, the upwelling and downwelling seems to be according to the tide’s direction.el. It stretches about 600m north to south and 750m east to west from its top.
