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.

Abstractoce-0083918在过去的二十年中，Scripps海洋学研究所的二氧化碳研究小组一直在收集海水样品，目的是分析在海水中溶解的无机碳，以此作为检测和理解与大气二氧化碳升高相关的长期变化。 为了继续并更新这项工作，在该项目中，Scripps将（1）重新评估该组使用的操纵仪器测量系统的校准，（（2）完全溶解的无机碳，碱度，碱性和13C/12C的同位物质分析，并在储存的材料中进行了验证，并在（3）上调整了（3），并将其调整为（3），并（3）dever defiier defiier deforber-conterban deSeard deSeard deSeard deSeard deSeard deSeard deSeard deSever deSever-deSeard decrban doile defiore doile defiore defior deford deSeards of（3）基于新的压力计校准的数据。 对测量设施的持续运行对于海洋和全球碳循环研究至关重要。
