Permafrost has long been considered to be a stable subgrade in the design and construction of roads in high latitude/altitude regions. However, as permafrost thaws, it loses its bearing capacity, and as a result, the overlying road surface to cracks, ruts, or even collapses. Michelle's study aims to quantify the thermo-physical properties of selected road surface types widely used in the NWT and evaluate their capacity to insulate and protect the underlying permafrost. Her project will also include recommendations for reducing damage to road surfaces due to permafrost thaw for a wide range of conditions.
Igor's research develops advanced permafrost restoration and thaw mitigation systems, and evaluates the effectiveness of such systems for a wide range of applications. Such applications include protection of infrastructure and stabilisation of permafrost to increase slope stability. Much of the new knowledge, tools and methods developed in this project is targeted for the protection of transportation infrastructure in the NWT and elsewhere in the circum-polar region. Scotty Creek serves as the main "out door laboratory" for the development and testing of these ground-freezing systems.
Maude is examining how the microtopography of collapse scar bogs evolve as they slowly drain following the thaw of "permafrost dams" on their margins. Her preliminary work indicates that such bogs develop hummocky surfaces over periods of years to decades, and that the introduction of hummocks affect water flow and storage processes and pathways.
Ela is developing and testing new ground freezing systems along a seismic line where permafrost has thawed preferentially. Her designs include various types of passive and active thermosyphon systems, as well as innovative designs that enhance ground cooling. The coldest ground at Scotty Creek is the ground below Ela's ground freezing systems!

Allison's M.Sc. examined the energy balance implication of mite infestations on shrubs species at Scotty Creek. It was found that the transpiration rates from shrubs infested with gall-forming mites are greatly reduced. This reduction has the potential to alter the partitioning of energy at the scale of individual leaves and increase the soil moisture content below the shrubs. Allison is now the Strategic Research Initiatives Officer at Wilfrid Laurier University in Waterloo, Canada.
