해양레이더를 이용한 제주해협 표층해류 관측

Abstract

High Frequency(HF) Ocean radar are valuable for marine ecological, economic, and safety applications marine transportaion, search and rescue, harmful algal blooms tracking and oil spill response as well as coastal sea surface circulation studies and forecast. Therefore, HF ocean radars on the global basis are over 300 systems monitoring oceans in over 26 countries and more than 110 radar stations are in operation in Asia and Oceania countries. Korea Institute of Ocean Science & Technology(KIOST, its old name was Korea Research and Development Institute,KORDI) to observe the surface current fields in the Jeju Strait installed a pair of SeaSonde HF ocean radar of 13 MHz at two sites of Jeju-do (Aewol and Kimyung) in 2012 and now operating. A comparison between surface current velocities measured by HF ocean radar and moored acoustic Doppler current profiler(ADCP) shows a good relationship with the correlation coefficient of 0.85 and the root-mean-square velocity difference of 18.6 cm/s in major axis of principal component. The mean current field measured by HF radar is well represented the Jeju Warm Current that rounds Jeju-do clockwise and passes to the east through the southern part of Jeju Straits.on studies and forecast.
