1997～ 1 998年台湾海峡两个航次的数据表明 ,颗粒有机碳 (POC)的平均含量为 0 .1 2 0± 0 .0 0 9mg/dm3 ,表层POC浓度在夏季和冬季分别存在几个高值区。POC在随深度变化的剖面分布图中 ,最大值出现在 1 0m层 ,底层水明显受再悬浮影响 ,这一剖面的变化规律普遍存在于整个海区及不同季节。夏季POC的深度变化幅度要显著大于冬季 ,这与垂直混合作用有关。POC与Chl a相关性较差 ,暗示以Chl a估算浮游植物的不确定性及POC产生及来源的复杂性。
The data of two voyages in the Taiwan Strait from 1997 to 1998 showed that the average content of POC was 0.12 ± 0.909 mg / dm3. There were several high POC concentrations in summer and winter, respectively Value area. In the distribution profile of POC with depth, the maximum appears in 10 m layer, and the bottom water is obviously affected by resuspension. The variation rule of this section is widespread in the whole sea area and in different seasons. The depth of summer POC changes significantly larger than winter, which is related to vertical mixing. The correlation between POC and Chl a is poor, implying that Chl a is used to estimate the uncertainty of phytoplankton and the complexity of origin and origin of POC.
