Objective(s): The objective is to test the thermal properties of straw bales and reflective surfaces for use on permafrost slopes along a potential pipeline route in the Mackenzie Valley. These materials might be used in conjunction with or as alternatives to wood chips to protect the exposed slopes from surface erosion and reduce the rate of thawing. Information that will be gathered during the test includes temperatures beneath the straw bales and reflective surfaces during the late winter period and during the thaw period of May through September. As well, the test will assess the physical degradation of the materials due to decomposition, UV exposure, rodents, etc. The test will continue through the winter of 2007 in order to gain multi-year data.
