International Research Fellowship Program: River Metabolism Within the Amazon Basin: Constraints on the ROMBUS Model

0107270 Aufdenkampe国际研究员奖计划使美国科学家和工程师能够在国外进行三到二十四个月的研究。 该计划的奖项提供了联合研究的机会，以及使用独特或互补的设施，专业知识和国外的实验条件。该奖项将支持博士安东尼Aufdenkampe二十四个月的博士后研究奖学金，与博士。CENA的维多利亚和亚历克斯·V·克鲁什博士以及南卡罗来纳州大学的罗恩·本纳博士。 支持这个项目的是来自生态系统研究计划的生物部和美国-这些实验旨在实现两个目标：（1）开发河流新陈代谢的经验关系，作为水成分，流量过程线和子流域特性的函数，立即适用于ROMBUS模型的第一个参数化。 (2)从生物能量学的更详细的角度来解释河流中微生物有机物的转化，这是对这些过程的更机械参数化的第一步，拟议研究的目标是探索亚马逊河系统内有机物矿化速率的控制。 该项目的好处是，它将促进我们对亚马逊河流域和河流生态的了解，并为我们提供更好地了解河流代谢和水的组成。

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.
