Abstract
Forest fires are known to have lasting thermal impacts on permafrost, but there are no previous studies of such effects along the eastern Canadian coastline. One-dimensional thermal modelling was used to examine the ground thermal regime at a coastal forest fire site in the discontinuous permafrost zone near Nain (56.5°N), Nunatsiavut, eastern Canada. Simulations were undertaken for both the unburned forest and adjacent fire-disturbed area, which were modelled to have an initial permafrost thickness of 15.6 m in 1965. Future scenarios incorporated changes to regional air temperature following Representative Concentration Pathway (RCP) 4.5 and... more
