Abstract

This study propose a new method to detect Cochlodinium polykrikoides red tide occurring in South Sea of Korea using Water-leaving Radiance data and Absorption Coefficients data of Geostationary Ocean Color Imager (GOCI). C. polykrikoides were analyzed and the irradiance and light emission characteristics of the wavelength range from 412 nm to 555 nm were confirmed. The detection technique proposed in this study detects the red tide occurring in the optically complex South Sea. Based on these results, it can be used for future red tide prevention.

본 연구에서는 Geostationary Ocean Color Imager (GOCI)의 수출광량(Water-leaving radiance) 자료와 흡광계수(Absorption Coefficients) 자료를 이용하여 한국 남해에 발생한 Cochlodinium polykrikoides 적조를 탐지하는 방법을 제안한다. C. polykrikoides의 분광스펙트럼을 분석하여, 412 nm에서 555 nm구간 파장대의 수출광 및 흡광 특성을 확인하였고 이를 이용하여 적조지수를 개발하였다. 본 연구에서 제안한 탐지기법은 광학적으로 복잡한 남해에서 발생한 적조를 탐지하였으며, 이러한 결과를 바탕으로 향후 적조 방재에 활용될 수 있을 것이라 판단된다.
