The Quality Control of Oceanic Carbon Dioxide Measurements: Preparation & Distribution of Reference Materials

表征海水中二氧化碳及其各种无机形态的化学性质，对于理解海洋在二氧化碳海气交换和全球气候调节中的作用至关重要。为了实现海洋二氧化碳测量的全球覆盖，世界各地的科学家和实验室必须相互合作和共享数据。然而，如果不能保证每个实验室都能准确和精确地测量海水中的二氧化碳，这将是一项毫无意义的工作。在这个项目中，首席研究员建议继续他的计划，生产，认证，并向国际社会分发海水中二氧化碳的标准参考物质。将被认证的海水CO2系统参数包括总溶解无机碳（TIC）、总碱度（TA）、氢离子浓度（pH）和碳同位素组成。目的是确保世界各地海洋二氧化碳测量的可比性。

ABSTRACTOCE-9819007Characterizing the chemistry of carbon dioxide and its various inorganic forms in seawater is essential to understanding the role played by the ocean in the sea-air exchange of carbon dioxide and the regulation of global climate. To achieve global coverage of carbon dioxide measurements in the sea, scientists and laboratories around the world must cooperate and share data with one another. Nevertheless, this would be a meaningless exercise without some assurance that each laboratory is capable of accurate and precise measurement of seawater carbon dioxide. In this project, the principal investigator proposes to continue his program of producing, certifying, and distributing to the international community a standard reference material for carbon dioxide in seawater. The parameters of the seawater CO2 system that will be certified include total dissolved inorganic carbon (TIC), total alkalinity (TA), hydrogen ion concentration (pH), and the carbon isotopic composition. The objective is to assure intercomparability of oceanic CO2 measurements around the world.
