ABSTRACT PROPOSAL # : DEB-9701714 INVESTIGATOR(S) : HAMILTON INSTITUTION: MICHIGAN STATE UNIVERSITY The aims of this research are to investigate linkages between hydrology, biogeochemistry, and ecology of wetlands in glacial landscapes, with the long-term aim of developing a predictive understanding of the relative sensitivity of different wetlands to climate change. The research plan involves monitoring of a large number of different wetlands in relation to annual variation in climate, and as part of the NSF CAREER program it includes significant student participation through class projects and independent research. The wetlands to be studied are all in central Michigan. The general hypothesis is that the variability among wetlands can be explained by variability in a small number of key hydrologic processes including groundwater inputs, hydraulic residence time, and seasonal pattern of flooding and desiccation. These same variables will also control responses to climate change.

摘要提案编号：DEB-9701714 调查员：汉密尔顿 机构：密歇根州立大学 这项研究的目的是调查冰川景观中湿地的水文学、生物地球化学和生态学之间的联系，长期目标是对不同湿地对气候变化的相对敏感性进行预测性了解。该研究计划涉及监测大量不同湿地与气候年度变化的关系，并且作为 NSF 职业计划的一部分，它包括大量学生通过课堂项目和独立研究参与。 待研究的湿地均位于密歇根州中部。 一般假设是，湿地之间的变异性可以通过少数关键水文过程的变异性来解释，包括地下水输入、水力停留时间以及洪水和干燥的季节模式。 这些相同的变量也将控制对气候变化的反应。
