项目摘要

The dissolved organic carbon (DOC) in the world ocean is part of the global carbon cycle that interacts with the planetary climatic system through its connection with atmospheric carbon dioxide. Keeping track of this DOC requires the cooperative effort of many marine laboratories worldwide. Making sure that all of these laboratories are making accurate DOC measurements requires that each one have access to a standardized sample of seawater for which the DOC concentration is set by international consensus. This award will fund the University of Miami to continue a consensus reference material (CRM) program that was first developed in 1998 in support of consistent, high quality measurements of dissolved organic carbon by the international ocean chemistry community. With continuation of this work, the US and international communities will create with confidence consistent measurements of a major marine carbon reservoir, thereby advancing society?s ability to assess changes in the marine carbon cycle and the role of the ocean in climate change.With continued strong international efforts to investigate the marine carbon cycle, the existing CRM program provides the necessary benchmark for globally comparable marine DOC measurements. Water from the deep Florida Strait (~42 mol/kg DOC) will be collected, ampoulated, and distributed to the US and international community. Since program launch, 126,000 ampoules of deep seawater and 90,000 ampoules of low carbon water have been distributed to 240 US and international laboratories in 42 nations at the rate of 13,000/year. With renewal of the reference material program for a sixth 3-year period of support, distribution of deep ocean water containing biologically refractory dissolved organic carbon and low carbon reference water will continue to aid the analytical work of the DOM community. A website is maintained that provides direct and convenient links to a growing number of DOM data collected from the global ocean.
世界海洋中的溶解有机碳(DOC)是全球碳循环的一部分,通过与大气二氧化碳的联系与行星气候系统相互作用。 跟踪DOC需要全世界许多海洋实验室的合作努力。 要确保所有这些实验室都能进行准确的DOC测量,就需要每个实验室都能获得标准化的海水样本,而DOC浓度是由国际共识确定的。该奖项将资助迈阿密大学继续进行1998年首次开发的共识参考材料(CRM)计划,以支持国际海洋化学界对溶解有机碳进行一致,高质量的测量。 随着这项工作的继续,美国和国际社会将有信心建立一个主要的海洋碳库的一致测量,从而促进社会发展?随着国际社会对海洋碳循环研究的持续努力,现有的CRM计划为全球可比的海洋DOC测量提供了必要的基准。 来自佛罗里达海峡深水(约42 mol/kg DOC)的水将被收集、装瓶并分配给美国和国际社会。自项目启动以来,126,000安瓿深海海水和90,000安瓿低碳水已被分发到42个国家的240个美国和国际实验室,每年13,000安瓿。随着参考物质计划的第六个3年支持期的更新,含有生物难降解溶解有机碳的深海水和低碳参考水的分配将继续帮助DOM社区的分析工作。 维持了一个网站,提供与从全球海洋收集的越来越多的DOM数据的直接和方便的链接。
