dc.description.abstract 통영 연안 해역에서 chlorophyll-a 농도 변화 패턴과 그에 따른 식물플랑크톤 군집 변동을 파악하기 위해 62일간 연속 관측(2017년 7월 29일~9월 28일) 및 주 1~2회의 주기적인 식물플랑크톤 군집 분석을 실시하였다. 조사기간 동안 chlorophyll-a 농도가 증감하는 변화가 3회 발생하였다. 첫 번째 chlorophyll-a 농도 변화(8월 6일~14일)에서는 14~16시 급격한 증가가 반복적으로 나타났으며, 이는 식물플랑크톤 군집 중 최우점종으로 출현한 와편모조류 Alexandrium affine의 일주수직운동에 의한 결과이다. 두 번째(8월 24일~30일) 및 세 번째(9월 12일~17일) 변화는 Chaetoceros curvisetus, Skeletonema marinoi-dohrnii complex등의 규조류에 의해 증가하였으며, 이때 규조류는 event 1의 A. affine의 14~16시에 급격한 증가와 달리 특정 시간에 관계없이 증가하였다. 또한 실시간 chlorophyll-a 농도의 연속 관측을 통해 A. affine의 일주수직운동 및 특징적인 chlorophyll-a 농도 변화 양상을 찾아냈으며, 3회의 chlorophyll-a 농도에 대한 변화는 7~12일의 간격을 두고 증가하였다. To understand the changes in chlorophyll-a concentration and phytoplankton community in Tongyeong coastal waters, Korea, we continuously monitored chlorophyll-a concentrations using a fluorescence sensor from July 29 to September 28, 2017(62 days). Furthermore, phytoplankton analyses were conducted periodically to monitor changes in dominant species affected by variations in chlorophyll-a concentrations. In the presented study, chlorophyll-a concentrations increased rapidly three times(event 1~3). During the first event(August 6 to 14), rapid and repeated increases in chlorophyll-a concentration during every 14:00 to 16:00 pm were the result of the diel vertical migration of Alexandrium affine(the dominant species during the event). The second and third events occurred from August 24 to 30 and September 12 to 17, respectively. During these events, increases in chlorophyll-a concentrations were caused by diatoms(common species: Chaetoceros curvisetus, Skeletonema marinoi-dohrnii complex etc.). Unlike event 1, we did not observe any characteristic changes such as vertical migration of A. affine during these events. Therefore, the continuous monitoring of chlorophyll-a concentrations using a real-time detection device, such as a fluorescence sensor, is necessary and important because of the variations that occur in chlorophyll-a concentration and phytoplankton community in the short-term. -
