초록

적조는 연안 해역에서 양식어류를 폐사 시키는 등 많은 경제적 피해를 입혀왔다. 이러한 적조의 광역 분포를 효과적으로 파악하기 위하여 원격탐사가 활용되어 왔는데, 적조 해수가 가지는 흡광 특성은 원격탐사에 중요한 요소인 해수반사도를 이해함에 있어서 핵심적인 역할을 한다. 본 연구에서는 2017년 8월 통영 인근 해역에서 출현한 Alexandrium affine 종이 우점한 해수에 대한 흡광 특성을 분석하였다. 선박 관측을 통하여 총 20개 정점에서 획득한 시료에서 색소 흡광, 부유물 흡광, 용존유기물 흡광을 측정하였고, 이를 수질 변수인 엽록소 농도, 부유물 농도와 관련하여 분석하였다. 분석 결과, 규조류 우점 해수와는 다르게 Alexandrium 우점 시료는 400 nm 이하에서 강한 흡광을 나타내었고, 또한 400 nm - 500 nm 에서 굴곡이 크게 나타남을 확인하였다. 색소 흡광의 집적 효과 또한 규조류와 다르게 나타남을 확인하였고, 부유물 및 용존유기물 흡광 모델 (adg(λ)=adg(λ0)e-s(λ-λ0))에서의 지수부 계수(s) 역시 기존 규조류에서 일반적으로 사용하는 0.015와는 달리 0.01이 더 적합함을 보였다.

Red tide has caused massive fish kills in Korean coastal waters with devastating economic loss in the aquaculture industry since 1995. Remote sensing technique has shown to be effective for the detection of red tide in wide areas, where the absorption property of red tide water plays a central role in understanding the red tide reflectance. This study analyzed the optical absorption property of sea waters dominated by the dinoflagellate specie of Alexandirum affine, off the Tongyeong area in August, 2017. Water samples collected from 20 stations in the ship-based campaign were measured for absorption by pigment, suspended solid, and dissolved organic matter, with the corresponding water quality variables such as chlorophyll concentration and total suspended solid. The analysis showed that Alexandrium-dominated water exhibits strong absorption in the spectral range below 400 nm unlike that of diatom-dominated waters, and greater fluctuations in the range of 400 nm - 500 nm. The packaging effect in pigment absorption was stronger in Alexandrium-dominated waters, and the exponent in the absorption by detritus and gelbstoff is disparate for diatom and Alexandrium. In the model for the detritus and gelbstoff absorption (adg(λ)=adg(λ0)e-s(λ-λ0)), the optimal exponent coefficient(s) for the Alexandrium was close to 0.01 rather than to 0.015, which was commonly use for modelling diatom waters.
