ABSTRACTOCE-0083918For over two decades the Carbon Dioxide Research Group at the Scripps Institution of Oceanography has been collecting seawater samples with the goal of assaying dissolved inorganic carbon in seawater as a means of detecting and understanding long-term changes associated with rising atmospheric carbon dioxide. In this project in an effort to continue and update this work, the Scripps investigators will (1) re-evaluate the calibrations of the manometric instrumental measurement systems utilized by the Group, (2) complete dissolved inorganic carbon, alkalinity, and 13C/12C isotopic analyses of stored samples backlogged over the years, and (3) adjust any past seawater-carbon dioxide Certified Reference Materials and data based on the new manometer calibration. Continued operation of the manometric measurement facility is of great importance to ocean and global carbon cycle research.

20多年来，斯克里普斯海洋研究所的二氧化碳研究小组一直在收集海水样本，目的是测定海水中溶解的无机碳，作为检测和了解与大气二氧化碳上升相关的长期变化的一种手段。 在这个项目中，为了继续和更新这项工作，斯克里普斯研究人员将（1）重新评估该小组使用的测压仪器测量系统的校准，（2）对多年来积压的储存样品进行完整的溶解无机碳、碱度和13 C/12 C同位素分析，及（3）根据新的压力计校正，调整以往的海水-二氧化碳标准物质及数据。 测压设施的持续运行对海洋和全球碳循环研究具有重要意义。
