摘要
依据2011年3月4日对胶州湾走航连续实测所得pCO2数据,结合水文、化学和生物等要素的同步实测资料,对胶州湾海域pCO2分布及其影响因素进行了初步探讨,并估算了3月海-气CO2通量。结果表明:3月胶州湾表层海水pCO2实测值在191～332μatm之间,平均值为278μatm,海-气CO2通量在-22.76～-7.13mmol·m-2·d-1,平均值为-14.2mmol·m-2·d-1,这一时期胶州湾从大气吸收约1.59×103t C,表现为大气CO2的强汇。生物活动是影响这一时期表层海水pCO2分布的主要原因。
Distribution and controlling factors were discussed based on the data obtained through continuous underway measurements of pCOz and relating parameters in hydrology, chemistry and biology. The results showed that the sea surface pCOzin Jiaozhou Bay in March ranged from 191 to 332 μatm,with an average of 278 μatm, and the air-sea CO2 flux was -22. 76 to -7.13 mmol · m ^-2·d ^-1, with an average of -14. 2 mmol· m ^-2·d ^-1 The whole Jiaozhou Bay acted as a strong sink of CO2 to the atmosphere and absorbed about 1.59 × 10at C during this period. Distribution of pCO2 in March was mainly controlled by biological uptake.
