ABSTRACTOCE-0622379The success of the international effort to observe and understand the distribution carbon dioxide in the world ocean and in the lower marine troposphere depends heavily upon a effective universal system of quality control of the measurements of CO2 concentrations in seawater. In this project, researchers at the Scripps Institution of Oceanography will continue their efforts to provide a mechanism for the quality control of the oceanic carbon dioxide measurements, in particular those that are made as part of international global programs. This will help to ensure that such measurements are comparable and accurate although made in different laboratories at different times; and will be an important factor in the design of a Global Ocean Observing System. To achieve this, the project leader and his team will prepare and certify reference materials for the parameters of the oceanic carbon dioxide system: total dissolved inorganic carbon, total alkalinity, hydrogen ion concentration, pH, and d13C for a sample of sea water. These reference materials will be distributed to US and to international investigators to assist in the quality control of oceanic CO2 measurements. They will also be used to provide test samples for use in collaborative studies of the analytical methods that are used to determine these various parameters. An important part of the project involves planning for the future. It is essential to assure a long-term supply of reference materials for future ocean science research, and it will be necessary to identify an agency or company that will take on this responsibility and relieve NSF of some of the burden. To encourage this, the investigators will interact with the US National Institute for Standards and Technology as well as with Ocean Scientific International (the IAPSO Standard Sea Water Service), and with various Japanese investigators to assess and recommend a plan for the future. This activity will have important broader impacts. The provision of reference materials to the international community of carbon cycle researchers works to improve the overall quality of oceanic carbon data around the world. Thus it is a significant contribution to research infrastructure in this field. As an educational endeavor, the existence of such a laboratory at a major US oceanographic institution ensures that undergraduate students and graduate students that work in the lab alongside this reference material program benefit from the education in high-quality analytical techniques that is part and parcel of such a program, and also from the ancillary discussions associated with quality control and quality assurance.

Abstractoce-0622379国际努力的成功观察和理解世界海洋和较低海洋对流层中二氧化碳的分布碳二氧化碳在很大程度上取决于对海水中二氧化碳浓度测量的有效通用质量控制。 在该项目中，Scripps海洋学研究所的研究人员将继续努力为海洋二氧化碳测量值，尤其是作为国际全球计划的一部分而提供的质量控制机制。这将有助于确保这种测量在不同时间在不同的实验室中进行的，尽管在不同的时间进行了可比性和准确性。它将是全球海洋观察系统设计的重要因素。为了实现这一目标，项目负责人及其团队将为海洋二氧化碳系统的参数准备和认证参考材料：总溶解的无机碳，总碱度，氢离子浓度，pH和D13C作为海水样品。这些参考材料将分发给我们和国际研究人员，以协助海洋二氧化碳测量值的质量控制。它们还将用于提供测试样本，用于用于确定这些各种参数的分析方法的协作研究。该项目的重要部分是为未来计划。必须确保为未来的海洋科学研究提供长期参考材料的供应，并且有必要确定将承担这一责任并减轻某些负担的机构或公司。为了鼓励这一点，调查人员将与美国国家标准技术研究所以及海洋科学国际（IAPSO标准海水服务）进行互动，并与各种日本调查人员进行评估并建议未来的计划。这项活动将产生重要的广泛影响。 向国际碳循环研究人员提供参考材料，致力于提高全球海洋碳数据的整体质量。因此，这是对该领域研究基础设施的重要贡献。 作为一项教育努力，在美国主要海洋学机构的这种实验室的存在确保了在实验室中与该参考材料计划一起工作的本科生和研究生受益于此类计划的一部分，也是与质量控制和质量保证有关的高质量分析技术的教育。
