Abstract

The objective of this paper is to explore the short-term variability of sea surface temperature (SST) and chlorophyll a (Chl-a) derived from satellite in the upwelling region of the southeast coast of Korea in summer. We particularly emphasize the spatial variability of SST and Chl-a in the East Korean Warm Current (EKWC) during summer monsoon. Spatial distribution of SST and Chl-a in the EKWC are described using SeaWiFS and AVHRR images in August, 2007. Spatial distribution of SST and Chl-a around EKWC can be classified into four categories in the profile of SST and Chl-a images: (1) coastal cold water region, (2) cold water region of thermal front, (3) warm water region, (4) cold water of offshore region.

본 연구에서는 위성관측 해양표면수온과 클로로필 영상 및 현장관측 자료를 이용하여 동해남부 냉수대 발생 주변해역의 단기변동을 조사하였다. 특히 본 연구에서는 2007년 8월 하계 계절풍 기간 동안의 동한난류 주변의 해양표면수온과 클로로필의 공간변동에 주목하였다. 본 연구기간에 조사한 동한난류 해역의 해양표면수온과 클로로필의 공간분포는 (1) 연안 냉수대해역, (2) 수온전선의 냉수대해역, (3) 동한난류해역, (4) 외해 냉수해역으로 구분할 수 있었다.
