다국어 초록 (Multilingual Abstract)

Deep current was observed at 620 m and 790 m in water 840 m deep off the mid-east coast of Korea from August 26 to November 7, 1986. Data analysis showed that the deep current in the subinertial frequency range was directed to southeast with a vector-average speed of about 3 cm/s. The deep flow had a large temporal variability with the same pattern of variation at the two depths. The maximum speed of the low-frequency current reached to a value larger than 11 cm/s just after the passage of Typhoon Vera over the study area. We also observed occurrence of sharp direction changes from southeast toward north persisting for a few days.
