The Quality Control of Oceanic Carbon Dioxide Measurements: Preparation, Certification, and Distribution of Reference Materials.

观测和了解全球海洋和海洋对流层下部二氧化碳分布的国际努力的成功很大程度上取决于海水中CO2浓度测量的有效通用质量控制系统。 在这个项目中，斯克里普斯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的质量控制提供一种机制，特别是那些作为国际全球计划一部分的海洋二氧化碳测量。这将有助于确保这种测量虽然是在不同的实验室在不同的时间进行的，但具有可比性和准确性;这将是设计全球海洋观测系统的一个重要因素。为实现这一目标，项目负责人及其团队将为海洋二氧化碳系统的参数编制和认证参考材料：总溶解无机碳、总碱度、氢离子浓度、pH值和海水样品的d13 C。这些参考材料将分发给美国和国际调查人员，以协助海洋CO2测量的质量控制。它们还将用于提供供用于确定这些不同参数的分析方法的合作研究的试验样品。该项目的一个重要部分涉及对未来的规划。确保为未来的海洋科学研究长期提供参考材料是至关重要的，有必要确定一个机构或公司来承担这一责任，并减轻NSF的一些负担。为了鼓励这一点，调查人员将与美国国家标准和技术研究所以及海洋科学国际（IAPSO标准海水服务）以及日本的各种调查人员进行互动，以评估和建议未来的计划。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有助于提高世界各地海洋碳数据的总体质量。因此，这是对该领域研究基础设施的重大贡献。 作为一种教育奋进，在美国主要海洋学机构这样一个实验室的存在，确保了在实验室工作的本科生和研究生，以及这个参考材料计划受益于高质量的分析技术教育，这是这样一个计划的一部分，也从与质量控制和质量保证相关的辅助讨论。

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.
