An essential requirement in evaluating the potential impacts of climate warming in Polar Regions, is a greater understanding of the nature and behavior of the active layer and the permafrost system. Numerous studies have documented the inherent capacity of permafrost to limit significant degradation from seasonal thawing because of the ability of overlying soil layers to dissipate influxes of heat. However, information on the degree to which these layers are able to act as buffers to permafrost degradation is limited, and thus further research on this system is needed.The research presented in this thesis in the form of two manuscripts. The first manuscript (Chapter 3) discusses the role of chemical processes in the soil weathering regime o...
