摘要
根据中国第15、16次南极考察观测的颗粒有机碳、叶绿素a浓度的数据 ,探讨浮游植物现存量对南大洋颗粒有机碳的贡献。结果表明 ,普里兹湾内浮游植物碳对颗粒有机碳的贡献高于湾北部的大洋区 ,真光层上部浮游植物碳对颗粒有机碳的贡献高于深层水。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。
Data on chlorophyll a and particulate organic carbon(POC)concentrations,taken during the15th and16th China Antarctic expeditions(CHINARE XV/XVI),were used to investigate the contribution of phytoplankton(Cph)standing stock on POC in the Southern Ocean.Results showed Cph to POC in Prydz Bay was higher than in the Bays northern ocean area.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 concentrations were also analysed to further understanding of the role of phytoplankton standing stock on POC in this area.
