依据2007年4~5月在北黄海走航连续观测所得pCO2数据,结合水文、化学、生物等要素的同步观测资料,对该海域pCO2的分布特征及其影响因素进行了探讨。调查结果表明:春季北黄海表层海水pCO2测得值在335~495μatm之间,统计平均值为393μatm,其中黄海混合水海域由于受生物活动、碳酸盐体系和温跃层等因素共同作用为大气CO2的汇区;辽南沿岸大部分海域由于受生物活动影响为汇区;而山东半岛北岸受渤海沿岸水输入影响的泥沙沉积区、成山角冷水涌升区及西朝鲜冷水海域为大气CO2的源区。
Based on the pCO2 data from continuous observations of the North Yellow Sea from April to May in 2007, the distribution characteristics of pCO2 and its influencing factors in this area were discussed with the simultaneous observation of hydrological, chemical and biological elements. The survey results show that the pCO2 values of surface seawater in the North Yellow Sea in spring are between 335 and 495 μatm, with a statistical average of 393 μatm. The waters of the Yellow Sea mixed waters are affected by biological activities, carbonate systems and thermocline and other factors as the atmosphere CO2 in most of the coastal areas of South China Sea due to biological activities as a sink area; and the north shore of Shandong Peninsula by the Bohai Sea coast water input sediment deposition area, cold water rising Chengshajiao area and cold water in North Korea for the atmospheric CO2 Of the source area.
