Abstract
To investigate the vertical structure of current velocity in the southwestern part of the East Sea, current data surveyed in July 2005 were analyzed. The currents were measured with both ship-mounted and lowered acoustic Doppler current profilers. Current speeds were abruptly reduced at a boundary between the Tsushima Warm Current Water and the East Sea Intermediate Water. Current directions were also changed at the boundary. Thus the effect of the warm eddy on the deep current was small, although potential temperature and salinity showed a warm eddy shape in the deep layer. The boundary that divides the upper and the lower layers was matched with a level of sigma-0=26.9 kg/m3. Mean speed of the upper layer was 20.56±12.73 cm/s while the lower layer was 7.11±3.98 cm/s. The most conspicuous current in the lower layer was inflow to the Ulleung Basin in the western part of Ulleung Interplain Gap.filers.
