Contribution of Cph to POC in the upper waters was higher than in the deeper euphotic zone.During the same survey,distribution characteristics of chlorophyll a concentration... 同时分析两个航次测区叶绿素a浓度和航程途中叶绿素a浓度的分布,以期了解浮游植物在南大洋颗粒有机碳来源中的作用。
The euphotic is the brightly lit upper zone where drifting phytoplankton carry out photosynthesis and are responsible for about 40% of the world's photosyn-thetic activity. 适于绿色植物生长之海水最上层是较上面地带，漂流的浮游植物在此处进行光合作用，而负责大约全世界40%25光合活动，营养物质的含量水准低。
Biological production and consumption of DMS, primarily taking place within the marine euphotic zone, are considered to be the predominate source and sink of DMS in seawater. DMS的生物生产与消耗主要发生在海洋真光层。
