A warm eddy was continuously observed to the east of Sokcho, Korea from March to June 1992. This warm eddy had been formed in 1991, wintered to the east of Sokcho, and moved northward a little during April-June 1992. The diameter and the depth of the eddy were respectively about 160 km and about 330 m in March. The homogeneous (mixed) layer of 10$^{\circ}C$ and 34.2 psu water was found at the upper layer with the maximum size of about 130 km and maximum depth of about 230 m in March. The size of the eddy and homogeneous layer decreased in June. Maximum current velocity of the eddy was about 65 cm/s at the surface layer and exceeded20 cm/s at 200 m depth. It is shown that the flow field was nearly in geostrophic balance, but there was a little difference in the current velocity between ADCP and geostrophic calculation in June. The surface velocity of the East Korean Warm Current(EKWC) was 50∼70cm/s which was very similar to the northward current velocity of the eddy. The EKWC water appeared in the layer upper than 200 m depth.
