Abstract

As the positive feedback between the absorption of chromophoric dissolved organic matter (CDOM) and acceleration of ice melt can impact the aquatic biota and dynamic heat budget, long-term monitoring of the CDOM variation in the polar ocean is necessary. However, the monitoring of CDOM is not easy because of harsh weather and difficult access, especially in the Antarctic Ocean. Therefore, the purpose of this study was to find a suitable long-term monitoring site for CDOM variation; we selected Maxwell Bay and Marian Cove at Sejong Base and horizontal and vertical distributions of CDOM were measured. After a 72 hr time-series measurement test of the CDOM variation at Sejong Dock and Sejong Cape in Maxwell Bay, Sejong Dock was selected, as it does not haveland discharge effects. The seasonal variation of CDOM was evident and the average CDOM concentration of Maxwell Bay was comparable with the adjacent sea. The CDOM at Sejong Dock from February to November 2010 was the highest in the fall and winter and the lowest during spring and summer. Thus, based on our one-year CDOM data, we suggest that Sejong Dock in Maxwell Bay is suitable for long-term monitoring of CDOM as an indicator of photochemical and biological environmental change and an important factor in determining the heating budget in the Antarctic Ocean.

유색 용존 유기물의 빛 흡수와 해빙의 가속화는 수생생태계와 열수지 역동성 간의 양적 피드백에 영향을 줄 수 있으므로 극지 해양에서 유색 용존 유기물의 장기 모니터링이 필요하게 되었다. 그러나 극지 환경에서의 관측은 용이하지 않은 접근성과 거친 기상으로 장기 모니터링이 쉽지 않다. 따라서 유색 용존 유기물의 장기 모니터링 장소로서 남극 세종 기지의 가능성을 확인하기 위해, 마리안 소만과 맥스웰 만에서 유색 용존 유기물의 분포와 외부로부터의 영향을 파악하기 위한 관측을 수행하였다. 맥스웰 만 내의 세종 부두와 세종 곶의 72시간 유색 용존 유기물의 변동성을 관측하고, 외부 영향이 없었던 세종 부두에서 2010년 2월에서 11월까지 10개월간 유색 용존 유기물의 연간 변화와 계절변동을 관측하였다. 세종 부두의 유색 용존 유기물 농도는 가을과 겨울 동안 가장 높고 봄과 여름에 감소하는 뚜렷한 계절 변동성을 보였고, 남극 인근 해역에서 측정된 유색 용존 유기물 농도 자료와 비교하였다. 따라서 우리는 남극해의 열수지에 대한 중요한 요인이자 광화학적 및 생물학적 환경변화에 관한 지시자인 유색 용존 유기물을 장기 모니터링을 위해 적합한 장소로 맥스웰 만의 세종 부두를 제안한다.
