Determination of the Carbonate Properties in the Arabian Sea: Joint Global Ocean Flux Study

在阿拉伯海过程研究的远洋过程巡航期间，首席研究员将与另一位合作科学家分享对海水二氧化碳-碳酸盐系统进行核心测量的任务。四项测量中的两项——总溶解无机碳、二氧化碳分压（pCO2）、总碱度和pH值——是表征整个碳酸盐平衡系统所必需的。然而，在某些情况下，将进行全套测量以“过度确定”系统，以检查内部一致性。大气和地表水的二氧化碳分压将沿着巡航轨道连续测量。这类信息对于了解海气交换水平和全球范围内的二氧化碳动态至关重要。

GOYET 9310895 The principal investigator will share with another collaborating scientist the task of making core measurements of the seawater carbon dioxide-carbonate system during the pelagic processes cruises of the Arabian Sea Process Study. Two of four measurements total dissolved inorganic carbon, the partial pressure of carbon dioxide (pCO2), total alkalinity, and the pH -- are necessary for characterizing the entire carbonate equilibrium system. On some occassions, however, full sets of measurements will be made to "overdetermine" the system as a check on internal consistency. Both atmospheric and surface water pCO2 will be measured continuously along the cruise track. This kind of information is fundamental to understanding carbon dioxide dynamics at the level of sea-air exchange and on a global scale.
