　　报告简介： 

　　Greenhouse gas release from permafrost thawing is one of the largest uncertainties in future climate prediction. Improving such prediction relies on a better representation of the interactions between hydrological, geochemical and microbial processes in the Arctic ecosystem that occur over a wide range of space and time scales and how they are linked with GHG flux dynamics above ground under dynamic freeze-thaw conditions. As part of the Next Generation Ecosystem Experiments in the Arctic (NGEE-Arctic), extensive studies have been conducted to characterize the permafrost region in our research site in Barrow, AK and to study below ground hydrological and biogeochemical properties and processes that are closely linked with above ground GHG fluxes.  

　　This presentation will give a summary review of the study they have conducted at Barrow, AK within the NGEE-Arctic program funded by U.S. Department of Energy and how that could be linked with similar studies elsewhere, such as those ongoing in the mountain permafrost on the Tibetan Plateau.  

　　欢迎各位老师和同学参加！
