Carbon Dioxide Measurements on the Global Ocean Flux Pilot Study

测量海水的总二氧化碳含量，以及二氧化碳分压和碱度，将作为JGOFS北大西洋试点研究的美国部分的一部分。主要的工具将是气体萃取-库仑滴定测量碱度和气相色谱测量二氧化碳。该方法的精度是2000年的1分之1，因此可以检测海洋中碳的自然循环，分辨率与经典的氧循环研究大致相同。这为平衡描述海洋中基本过程的方程开辟了道路。在这些巡航中，将检查整个春季发生的二氧化碳的时间变化，可能精确到日循环的分辨率。这些数据将被添加到JGOFS数据集中。

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.
