In this project, researchers at the Scripps Institute of Oceanogrpahy will continue 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. As they have done under previous NSF awards for this activity, they will prepare and certify reference materials for the parameters of the oceanic carbon dioxide system: total dissolved inorganic carbon, total alkalinity, and hydrogen ion concentration, pH for a sample of sea water. The reference materials for total dissolved inorganic carbon and for total alkalinity will be based on natural seawater, sterilized, bottled, and analyzed using appropriate reference methods for these parameters. Reference materials for Tris will be based on synthetic seawater and analyzed using classical Harned cells. These reference materials will be distributed to US and to international investigators to assist in the quality control of oceanic CO2 measurements. During the course of this project, they expect to distribute at least 15,000 bottles of reference material. These materials will also be used to provide test samples for use in collaborative studies of the analytical methods 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. To encourage this, the principal investigator will interact with the US National Institute for Standards and Technology, the European Institute for Reference Materials and Measurements (IRMM) in Geel, Belgium 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. Broader Impacts: Infrastructure: The provision of reference materials to the international community of carbon cycle researchers helps to improve the overall quality of oceanic carbon data around the world both for field studies of the distribution of oceanic carbon, as well as for studies related to ocean acidification. Thus it is a significant contribution to research infrastructure in this field. Education: 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. It also provides a resource for other students in the institution who are interested in making high-quality carbon measurements as part of their research. The principal investigator is also called on to instruct others in CO2 measurements, both by telephone or e-mail conversations, and also in more formal courses. Outreach: The principal investigator will be involved in a number of public outreach efforts related to his research studies on the ocean carbon system. In particular, he expects to make a number of public presentations in the area of ocean acidification, as well as to work with Niijii Films (makers of A Sea Change) to develop materials for use in education related to this topic.

在该项目中，Scripps Oceanogrpahy研究所的研究人员将继续提供一种机制，以控制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。正如他们在先前的NSF奖项中为此活动所做的那样，他们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，总碱度和氢离子浓度，用于海水样品的pH值。总溶解的无机碳和总碱度的参考材料将基于天然海水，使用适当的参考方法对这些参数进行灭菌，瓶装和分析。 TRI的参考材料将基于合成海水，并使用经典的竖琴细胞进行分析。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。在该项目的过程中，他们希望至少分发15,000瓶参考材料。这些材料还将用于提供测试样品，以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项责任的机构或公司。为了鼓励这一点，首席研究人员将与美国国家标准技术研究所，比利时吉尔市的欧洲参考材料和测量研究所（IRMM）以及与海洋科学国际（IAPSO标准海水服务）以及各种日本调查人员进行评估和建议未来的计划。更广泛的影响：基础设施：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，均用于海洋碳分布的现场研究以及与海洋酸化有关的研究。因此，这是对该领域研究基础设施的重要贡献。教育：在美国主要海洋学机构中存在这样的实验室，可确保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高质量分析技术的教育，这是该计划的一部分，也可以从与质量控制和质量控制和质量控制和质量控制相关的辅助讨论中受益。它还为机构中的其他学生提供了一种资源，他们有兴趣作为研究的一部分进行高质量的碳测量。还要求首席调查员通过电话或电子邮件对话以及更正式的课程来指导其他人进行二氧化碳测量。外展：首席研究人员将参与与他关于海洋碳系统研究的许多公共外展工作。他特别希望在海洋酸化领域进行许多公开演讲，并与Niijii电影（Sea Change的制造商）合作，以开发用于与此主题相关的教育的材料。
