Abstract/OtherAbstract:
We investigated the partial pressure of carbon dioxide (pCO(2)) in Jiaozhou Bay (JZB), which is surrounded by the economically developed city of Qingdao, during two cruises undertaken in November, 2007 (autumn) and February, 2008 (winter). Results indicated that sea surface pCO(2) in autumn varied between 315 and 720μatm, with an average level of 418μatm. In winter the sea surface pCO(2) ranged from 145 to 315μatm with an average of 249μatm, which is below atmospheric pCO(2). Despite seasonal temperature variation between autumn and winter, it was noted that biological process (production and respiration) were responsible for both spatial and seasonal variation during these seasons. We found that Jiaozhou Bay served as a net atmospheric CO(2) source in autumn (November) (2.87mmolm(-2)d(-1)), while in winter (February) it served as a net sink (-16.22mmolm(-2)d(-1)).
