CAREER: Hydrologic Regulation of Wetland Biogeochemistry and Ecology and the Impacts of Climate Change

项目编号：deb9701714研究人员(S): HAMILTON机构：MICHIGAN STATE UNIVERSITY本研究的目的是研究冰川景观中湿地的水文、生物地球化学和生态学之间的联系，长期目标是建立不同湿地对气候变化相对敏感性的预测性认识。该研究计划包括监测大量不同湿地与年度气候变化的关系，并且作为NSF CAREER计划的一部分，它包括通过课堂项目和独立研究的重要学生参与。要研究的湿地都在密歇根州中部。一般的假设是，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性模式。这些相同的变量也将控制对气候变化的反应。

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.
