" 東海陸棚是全世界最寬廣的大陸棚之一，同時又有長江、黃河等兩大河流所輸出之陸源物質注入其中，而其高生產力更使其成為全世界最重要的漁場之一。此些特性使得東海成為一理想之天然實驗場，來進行大陸邊緣海域與開放性大洋之間，碳的交換過程與通量的研究。雖然，東海長期觀測與研究（三）總計畫中，對於顆粒態有機碳循環之研究已有完整規劃。然而，對海水中最重要碳的儲存庫—溶解態無機碳的觀測與研究，卻付之闕如。因此，本子計畫擬針對東海溶解態無機碳碳化學系統，進行系統性的觀測與研究，以彌補總計畫中此部分資料之不足。本計畫所擬定之具體研究目標，包括下列三項：(1) 東海是否存在「continental shelf pump」之作用機制？；(2) 長江流量與輸出物質通量的改變對東海溶解態無機碳碳化學系統有何影響？；(3) 亞洲沙塵暴對東海貧營養鹽區溶解態無機碳碳化學系統的可能影響。 " " The East China Sea shelf (ECSS) is one of the largest continental shelves in the world oceans. The enormous amounts of nutrients are reportedly supplied by the runoff of the Yangtze River and the year-round upwelling of Kuroshio off northeast of Taiwan. The high nutrient input renders the ECSS highly productive, and thus makes it an ideal site to study the carbon exchange between the shelf seas and open oceans. The Long-term Observation and Research of the East China Sea – III (LORECS-III) project has proposed a comprehensive plan to study the particulate carbon cycle in the ECS. Nevertheless, another important component in the oceanic carbon cycle study, i.e. the dissolved inorganic carbon system that is the largest reservoir of carbon in seawater, is not yet included in the integrated LORECS-III project. In order to fill this gap and to better understand the carbon cycle in the ECS, this sub-project aims to systematically study the carbonate system in seawater. The main goals of this proposed study are: (1) To testify whether the 「continental shelf pump」 works in the ECS; (2) to study the response of carbonate system in seawater to the change of Yangtze River run-off, in terms of both discharge and material fluxes; and (3) to understand the potential impact of Asian sand storm on the carbonate system in the ECS oligotrophic waters.
