摘要
根据2006年12月在北黄海走航连续观测所得数据,结合化学和生物等要素的同步观测资料,对该海域碳通量分布及其影响因素进行了探讨。结果表明:辽南沿岸流及其影响区域是大气CO2汇区;山东半岛以北沿岸,122°E以西受渤海环流输送,黄河悬浮颗粒物影响的高浑浊度区域是大气CO2的一个强源区;而占据北黄海大部的黄海混合水以及北黄海整体上是大气CO2的弱源。
Distribution and controlling factors of carbon flux were determined in the northern Yellow Sea during winter based on the data obtained using continuous underway measurements of related parameters in chemistry and biology during December2006.The region that is influenced by the Liaonan coastal current acted as a sink of atmospheric CO2,while the coastal region located in the north of Shandong Peninsula(west of 122°E),characterized by high turbidity due to high suspended solids transported by Bohai circulation,acted as a strong source and the maximum of pCO2.But on the whole the northern Yellow Sea acted as a weak source of atmospheric CO2 during winter mainly because the most part of the northern Yellow Sea was full of Yellow Sea Mixing Water that was oversaturated in pCO2.
