Support for the U. S. GEOTRACES Project Office

这项奖励将为哥伦比亚大学拉蒙特-多尔蒂地球天文台的美国地质追踪项目办公室提供三年的持续支持。该办公室在美国地球轨迹科学指导委员会的指导下工作，以支持GEOTRACES计划的所有方面，包括促进活动(标准参考材料的准备和分发；相互校准；建模；数据管理)和实地考察(科学规划；邮轮后勤；结果综合)。GEOTRACES计划旨在研究全球海洋生物地球化学循环中的微量元素及其同位素(TEI)，采用多种示踪剂方法来确定TEI的来源、汇和内部循环，同时尽可能量化这些过程的速率。TEIS的生物地球化学循环对碳循环、气候变化、海洋生态系统和环境污染等不同领域的研究具有直接影响。通过极大地促进对TEIS的海洋生物地球化学循环的了解，GeoTraces有望为这些地区的每一个领域带来明显的好处。更广泛的影响：通过让大量研究生和博士后参与，GeoTRACE有助于培训下一代海洋学家。在JGOFS和其他最近的项目中很明显，参与让年轻人受益，因为他们接触到了同龄人和潜在的未来雇主。它还向年轻人介绍开发新项目的程序及其带来的好处。GeoTraces还将社区建设确定为其最优先事项之一。在国际一级，这涉及扩大海上无污染采样技术的分布，并培训调查人员使用这些新技术。在美国，社区建设更侧重于与海洋学社区的其他部门分享GEOTRACES的经验，向那些希望走GEOTRACES道路的人免费提供信息、援助和建议，并组织他们自己的协调努力，解决海洋学中的重大问题，这些问题太过复杂，无法通过小团体或单独的PI项目来解决。

This award will provide three years of continuing support for the U.S. GEOTRACES Project Office at the Lamont-Dougherty earth Observatory of Columbia University. The Office works under the direction of the U.S. GEOTRACES Scientific Steering Committee to support all aspects of the GEOTRACES program, including enabling activities (preparation and distribution of standard reference materials; intercalibration; modelling; data management) and field expeditions (science planning; cruise logistics; synthesis of results). The GEOTRACES program is designed to study the global marine biogeochemical cycles of trace elements and their isotopes (TEIs), employing a multi-tracer approach to characterize the sources, sinks and internal cycling of TEIs while also quantifying the rates of these processes wherever possible. Biogeochemical cycling of TEIs has direct implications for research in such diverse areas as the carbon cycle, climate change, ocean ecosystems, and environmental contamination. GEOTRACES promises clear benefits to each of these areas by significantly advancing knowledge of the marine biogeochemical cycles of TEIs. Broader Impacts: GEOTRACES contributes to the training of the next generation of oceanographers by involving a large number of graduate students and post docs. It was evident in JGOFS and other recent programs that participation benefited young people by giving them exposure to peers and to potential future employers. It also informs young people about the procedures for developing new programs and the benefits thereof. GEOTRACES has also established community building as one of its highest priorities. At the international level, this involves expanding the distribution of technologies for contamination-free sampling at sea, and training investigators to use those new technologies. In the U.S., community building is focused more on sharing the GEOTRACES experience with other sectors of the oceanographic community, freely providing information, assistance and advice to those who wish to follow a path like that of GEOTRACES and organize their own coordinated effort to attack substantial problems in oceanography that are too complex to address by small groups or individual PI projects.
