Abstract

The low temperature, low salinity and low density sea water which was originated from the southern part of the Yellow Sea and distributed from the surface to 20 m depth was transported by the northwesterly wind during the period from the middle of March to the beginning of April, 1998 and had an influence on the northern coastal sea area of Cheju Island. Accordingly, this kind of accumulated data may supply the fundamental data for the realtime monitoring of oceanographic conditions and may improve degree of the forecasting accuracy of fishing and oceanographic conditions.

황해남부해역에 근원을 갖고 있는 저온 $\cdot$ 저염의 저밀도수가 춘계인 1998년 3월 중순부터 4월 초순까지 표층에서부터 약 20m층까지 분포하며 연취되는 북서계절풍에 편승하여 제주도 연안천해역으로 Ekman 수송되어 제주도 북부 연안천해역에 영향을 미쳤다. 따라서 이러한 자료의 축적을 통하여 해양환경의 Realtime monitoring을 위한 기초자료의 제공과 어$\codt$해황예보의 정도를 향상시킬 수 있는 중요한 자료를 제공하게 된다.
