The Southern Ocean (SO) plays a primary role in global climate by storing and transporting anthropogenic carbon dioxide through the meridional overturning circulation and the biological pumping process. In this study, we aim to investigate interannual variability of summer chlorophyll concentration ...

엔소가 남극해 전반에 걸쳐 클로로필 변동에 미치는 영향을 정량적으로 분석한 연구가 거의 없는 이유는 무엇인가? | 위에서 기술한 바와 같이 바람, 해면수온, 해빙, 해류와 같은 장기 해양환경 변화에 따른 클로로필 변화 기작과엔소에 따른 주요 물리변수의 변화는 비교적 잘 연구되어있으나, 엔소가 남극해 전반에 걸쳐 클로로필 변동에 미치는 영향을 정량적으로 분석한 연구는 학계에 보고된 바가 거의 없다. 이는 부분적으로는 시·공간적으로 제한된 현장관측 클로로필 자료의 부족에 기인한다. 이에 더하여 해색 위성센서로부터 얻어진 클로로필 자료 사이의 계통 오차도 연구를 제한하는 주요한 원인이다(Gregg and Casey2007). 기존 클로로필 자료가 가진 한계로 인하여 지금까지 남극해에서 엔소와 클로로필의 상관관계에 대한 연구는 주로 단일 위성 자료를 이용하여 계산된 클로로필 자료만을 사용하였고 연구 영역 또한 클로로필이 엔소에명확하게 반응하는 해역으로 국한되었다. | |
엔소는 남극 환경에 어떠한 영향을 미치는 것으로 알려져 있는가? | 라니냐 시기에는 남태평양에 저기압 어노말리가 발생하여 해빙과 해면수온, 바람 분포가 엘리뇨 시기와 정반대로 나타난다. 또한, 엔소는 남태평양 해역에서 남북방향 에크만 수송에 영향을 주어 남극순환류 위도를 변화시키고, 결과적으로 남극순환류 해역의 해양 물성 변동에 기여 하는 것으로 알려져 있다(Kim and Orsi 2014). | |
식물플랑크톤 번성에 복합적으로 연관되어 있는 요소에는 어떠한 것들이 있는가? | 2009). 장기 현장관측자료를 이용한 클로로필 변동에 관한 이러한 연구들은 해류, 해수 성층도, 해빙과 같은 남극해 주요 물리 변수가 식물플랑크톤 번성에 복합적으로 연관되어 있음을 시사한다(Lovenduski and Gruber 2005; Park et al. 2010; Sallée etal. |
