adj.[海]透光層的

This reduced the efficiency of upwelling to cool the suface and cut off the supply of nutrient rich thermocline water to the euphotic zone. 拉尼娜與厄爾尼諾性格相反，隨著厄爾尼諾的消失，拉尼娜的到來，全球許多地區(qū)的天氣與氣候災(zāi)害也將發(fā)生轉(zhuǎn)變。

This reduced the efficiency of upwelling to cool the suface and cut off the supply of nutrient rich themp3ocline water to the euphotic zone. 拉尼娜與厄爾尼諾性格相反，隨著厄爾尼諾的消失，拉尼娜的到來，全球許多地區(qū)的天氣與氣候災(zāi)害也將發(fā)生轉(zhuǎn)變。

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... 同時分析兩個航次測區(qū)葉綠素a濃度和航程途中葉綠素a濃度的分布,以期了解浮游植物在南大洋顆粒有機(jī)碳來源中的作用。

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. 適于綠色植物生長之海水最上層是較上面地帶，漂流的浮游植物在此處進(jìn)行光合作用，而負(fù)責(zé)大約全世界40%25光合活動，營養(yǎng)物質(zhì)的含量水準(zhǔn)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的生物生產(chǎn)與消耗主要發(fā)生在海洋真光層。
