Measurements of the total CO2 content of sea water, together with pCO2 and alkalinity will be made as part of the U.S. component of the JGOFS North Atlantic Pilot Study. The principal tool will be gas extraction - coulometry, with titrimetric measurements of alkalinity and gas chromatographic measurements of pCO2. The method has a precision of 1 part in 2000, and thus can examine natural cycles in the ocean for carbon with much the same resolution as in classical studies of oxygen cycling. This opens the way to balancing the equations describing fundamental processes in the ocean. In these cruises the time changes in CO2 taking place through the spring season, possibly down to the resolution of diurnal cycles will be examined. These data will be added to the JGOFS data set.

海水总二氧化碳含量、二氧化碳分压和碱度的测量将作为JGOFS北大西洋试点研究美国部分的一部分进行。主要的工具将是气体萃取-库仑法，用滴定法测量碱度和气相色谱法测量二氧化碳分压。该方法的精度为2000年的1 / 1，因此可以以与经典氧循环研究相同的分辨率来检测海洋中碳的自然循环。这为平衡描述海洋基本过程的方程式开辟了道路。在这些巡航中，二氧化碳的时间变化发生在整个春季，可能下降到昼夜周期的分辨率将被检查。这些数据将被添加到JGOFS数据集中。
