Abstract:An overview of the hydrology of Arctic wetlands, its controls and future implications will be presented. The presentation will focus on recent research on the role of permafrost on hydrology, including surface water, and how permafrost degradation at the sub-meter scale can alter watershed-scale hydrologic fluxes and stores. Also, ongoing and related research by others at U Alaska will be presented, including a large new project called the Next Generation Ecosystem Experiment (NGEE-Arctic). The presentation will be split between field measurements and modeling, with some recent remote sensing analyses - a mixture or past, ongoing and future work.
