위성해수면온도 자료를 이용한 한반도의 냉수대의 영향 분석

Abstract

This work investigates environment change during cold water events in the summer season in the east coastal area of Korea Peninsula. Cold water in coastal waters refers to areas whose average temperature is 5°C colder than surrounding areas. When Cold water expands and changes its extract direction, NFRDI(National Fisheries Research & Development Institute) issues an upwelling cold water warming. This analysis was performed based on the various environment factors using satellite data and in-situ data. The period of the study is summer of 2011~ 2014. We used NOAA of satellite data for SST analysis, the Geostationary Ocean color Imager (GOCI) level2 data for analysis of Chl-a and ocean current, wind of in situ. We calculated the cold water area when it is 5°C colder than in SST data.s.
