ABSTRACTOCE-0137287In this project, scientists at the Scripps Institution of Oceanography will continue to produce and distribute a standard reference material for the quality control of 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 Scripps laboratory will prepare standard materials (seawater) and certify them for the following parameters of the oceanic carbon dioxide system: total dissolved inorganic carbon, total alkalinity, hydrogen ion concentration, pH, and d13 C for a sample of sea water. These reference materials will be distributed to US and 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. As part of this work, the scientific team plans to organize various such collaborative studies and will collaborate with the various investigators to ensure that the experience gained is documented in reports and in written methods that are widely disseminated. 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. To encourage this, the investigators propose to interact with the U.S. 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.

Abstractoce-0137287在该项目中，Scripps海洋学研究所的科学家将继续生产和分发标准参考材料，以供海洋二氧化碳测量值，尤其是作为国际全球计划的一部分的质量控制。 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，Scripps实验室将准备标准材料（海水），并证明它们的以下参数：二氧化碳系统的以下参数：总溶解的无机碳，总碱度，氢离子浓度，pH和D13 C用于海水样品。 这些参考材料将分配给我们和国际调查人员，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。 作为这项工作的一部分，科学团队计划组织各种此类协作研究，并将与各种研究人员合作，以确保获得的经验记录在报告和书面方法中，这些方法被广泛传播。 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项责任的机构或公司。 为了鼓励这一点，调查人员建议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）和各种日本调查人员进行互动，以评估并建议未来计划。
