0107270AufdenkampeThe International Research Fellow Awards Program enables U.S. scientists and engineers to conduct three to twenty-four months of research abroad. The Program's awards provide opportunities for joint research, and the use of unique or complementary facilities, expertise and experimental conditions abroad.This award will support a twenty-four-month postdoctoral research fellowship for Dr. Anthony Aufdenkampe to work with Dr. Reynaldo L. Victoria and Dr. Alex V. Krusche of CENA and Dr. Ron Benner of the University of South Carolina. Support for this project is coming from the Ecosystem Studies Program of the BIO Division and the U.S.-Brazil Program in the Division of International Programs.These experiments are designed toward two objectives: (1) Develop empirical relationships of river metabolism as a function of water composition, discharge hydrograph, and sub-basin characteristics, to be immediately applicable to the first parameterization of the ROMBUS model. (2) Interpret microbial organic matter transformations in rivers from the more detailed perspective of bioenergetics, which is the first step toward a more mechanistic parameterization of these processes.The goal of the proposed research is to explore controls on rates of organic matter remineralization within the Amazon River system. The benefit of this project is that it will advance the knowledge of our understanding of Amazon River basin, and river ecology as well as provide us with a better understanding of river metabolism and water composition.

[10727 . 27]国际研究员奖励计划使美国科学家和工程师能够到国外进行3至24个月的研究。该计划的奖励为联合研究提供机会，并使用独特或互补的设施，专业知识和国外的实验条件。该奖项将为Anthony Aufdenkampe博士提供为期24个月的博士后研究奖学金，与CENA的Reynaldo L. Victoria博士和Alex V. Krusche博士以及南卡罗莱纳大学的Ron Benner博士合作。该项目由生物学部的生态系统研究项目和国际项目部的美国-巴西项目提供支持。这些实验旨在实现两个目标：(1)发展河流代谢作为水组成、流量线和子流域特征函数的经验关系，以便立即适用于ROMBUS模型的第一次参数化。(2)从更详细的生物能量学角度解释河流中微生物有机质的转化，这是对这些过程进行更机械参数化的第一步。拟议研究的目标是探索对亚马逊河系统内有机物质再矿化率的控制。这个项目的好处是，它将推进我们对亚马逊河流域和河流生态的认识，并为我们提供更好的了解河流代谢和水组成。
