摘要(Abstract)：
根据2006年6～7月对黄东海大面调查的资料,分析研究了黄东海颗粒有机碳(particulate organic carbon,POC)的浓度和分布特征。结果表明,夏季黄东海POC的浓度范围是6.07～2 204.17μg.L-1,平均浓度为147.15μg.L-1。POC整体上呈现近岸浓度较高、远岸浓度较低,北部浓度较高,南部浓较低的分布特点;在长江口外及浙江近岸海区存在POC的高值区,特别是长江口外,表层和底层POC浓度很高,这主要是受到长江陆源输入的重要影响。在垂直分布上,南黄海区POC的浓度分布整体上呈现上层水体浓度较低,下层水体浓度较高的特点,这主要是受底质再悬浮的影响。而东海区呈现近岸POC浓度较高,离岸POC浓度较低的特点,这主要是受长江冲淡水输入的影响。
