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.

在这个项目中，斯克里普斯海洋研究所的科学家们将继续生产和分发用于海洋二氧化碳测量质量控制的标准参考材料，特别是那些作为国际全球计划一部分的标准参考材料。这将有助于确保这种测量具有可比性和准确性，尽管这些测量是在不同的实验室在不同的时间进行的；这将是设计全球海洋观测系统的一个重要因素。为了实现这一目标，斯克里普斯实验室将准备标准材料(海水)，并验证它们符合海洋二氧化碳系统的以下参数：海水样本的总溶解无机碳、总碱度、氢离子浓度、pH和d13C。这些参考材料将分发给美国和国际调查人员，以协助海洋二氧化碳测量的质量控制。它们还将被用来提供测试样本，用于对用于确定这些不同参数的分析方法进行合作研究。作为这项工作的一部分，科学小组计划组织各种这样的合作研究，并将与各种调查人员合作，以确保所获得的经验被记录在广泛传播的报告和书面方法中。该项目的一个重要部分涉及到对未来的规划。必须确保为未来的海洋科学研究提供长期的参考材料，并有必要确定将承担这一责任的机构或公司。为了鼓励这一点，调查人员建议与美国国家标准与技术研究所、国际海洋科学组织(IAPSO标准海水服务)以及各种日本调查人员互动，以评估和建议未来的计划。
