项目摘要

0120735HolbenMore than a century of metal mining in the Northwest region of the U.S. has created numerous open water extreme environments with unusual metal and chemical composition. In addition to their status as Superfund sites, these environments also represent large-scale outdoor laboratories in which it is highly likely that unusual biogeochemical cycles and microbial metabolic strategies exist. We are requesting one year of funding through the SGER component of this program to facilitate development of a multidisciplinary, polyphasic approach that is generally applicable to resolving the chemical and biological components of biogeochemical cycling in a series of these extreme and unusual aquatic environments that vary in key biogeochemical parameters.Considering the unique nature of these environments, and the paucity of information on the biological component of the biogeochemical cycles, preliminary fundino, is necessary to develop appropriate sampling strategies, equipment and analytical techniques, assemble the requisite expertise, determine the key parameters to measure, and develop a model framework adequate for dealing with a suite of extreme aquatic environments proposed for future study. The requested year of funding will provide preliminary data, methodologies, and demonstration of feasibility that will allow us to prepare a full proposal for the 2002 Biocomplexity Program Call.

0120735Holben 美国西北部地区一个多世纪的金属开采创造了许多具有不寻常金属和化学成分的开放水域极端环境。除了作为超级基金地点的地位之外，这些环境还代表了大型户外实验室，其中很可能存在不寻常的生物地球化学循环和微生物代谢策略。我们请求通过该计划的 SGER 部分提供一年的资金，以促进多学科、多相方法的开发，该方法通常适用于解决一系列关键生物地球化学参数各不相同的极端和不寻常水生环境中生物地球化学循环的化学和生物成分。考虑到这些环境的独特性质，以及有关生物地球化学成分的信息的缺乏生物地球化学循环是初步的，有必要制定适当的采样策略、设备和分析技术，汇集必要的专业知识，确定要测量的关键参数，并开发一个足以处理未来研究提出的一系列极端水生环境的模型框架。所请求的资助年份将提供初步数据、方法和可行性论证，使我们能够为 2002 年生物复杂性计划征集准备一份完整的提案。
