Abstract
This poster summarizes the principal field installations and initial results of a long-term permafrost monitoring project at Herschel Island. The project is a collaborative initiative between Yukon Parks and Carleton University. The purpose is to investigate permafrost conditions on Herschel Island, and to examine how they have responded to the climate warming experienced throughout the western Arctic since 1970. Our data show that the mean annual ground temperature on Collinson Head is -8ºC, and we have obtained the ground temperature profile to 42 m depth, which shows that the ground has warmed from its previous equilibrium temperature of -10ºC. The temperature at the top of permafrost is measured on a transect downslope from Collinson Head, at 10 sites with varying snow cover. The range in mean annual ground temperatures at these locations is from -5ºC to -9ºC. Snow depths at these sites are measured by Park Rangers. The relation between snow depth and ground temperature obtained at Herschel in 2003-04 is precisely the same as obtained at Garry Island in 196970, a site that is normally 2ºC warmer than Herschel.
