摘要
就冬季东海陆架典型海域POC的垂直分布进行了研究。结果表明受黄海沿岸流影响的中陆架砂质区POC和悬浮体含量高,POC的垂直分布表现为从表层到底层逐渐增高;悬浮体含量低的中陆架济州岛西南泥质区和砂质区,POC含量低,其垂直分布比较均匀。POC的垂直分布与海水体中的总悬浮颗粒物浓度、陆源沉积物供应和海洋生物作用密切相关。
The contents of paniculate organic carbon (PCX') in the typical areas of the East China Sea (ECS) in winter (February, 1997) were analyzed, and POC's vertical distributions in the study area were discussed. The results show that the POC contents and concentrations of suspended matter are high in the middle shelf sand area corresponding to the Huanghai Coastal Current (HCC), where the POC vertical distribution shows that the contents of POC increase from the surface to bottom water layer, and the highest content of POC in this area is in the bottom water layer. The POC contents are relatively low in the southwest Cheju Island's mud area and middle shelf sand area with low concentrations of suspended matter, where the difference of POC contents from the surface to bottom water layer is not as big as that in the HCC influential area, indicating that the POC vertical distribution is high mixed relatively in the whole water column of the low concentration suspended matter area. It is suggested that the POC vertical distribution in the ECS in winter correspond to the concentration of total suspended matter, support of terrigenous mineral debris and organism production.
