9310594 MILLERO 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 occasions. 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.

9310594 Millero首席研究员将与另一位合作的科学家分享，在阿拉伯海工艺研究的上层过程中，对海水二氧化碳碳酸盐系统进行核心测量的任务。 四个测量中的两项 - 总溶解的无机碳，二氧化碳的部分压（PCO2），总碱度和pH值 - 对于表征整个碳酸盐平衡系统是必需的。在某些情况下。但是，将进行完整的测量值，以“过度确定”该系统，以检查内部一致性。大气和地表水PCO2将沿巡航轨道连续测量。这种信息对于在海上交换水平和全球范围内了解二氧化碳动态至关重要。
