Iain's research examines the rates and patterns of permafrost thaw below seismic lines, and the impacts of such thaw on the hydrological interaction between seismic lines and the surrounding landscape. He is using a combination of archived geophysical, thermal and hydrological data along an intensively studied seismic line, as well as modelling approaches to simulate coupled thermal and mass transfer into and along the line.
Michael's research contributes to the Dehcho Collaborative on Permafrost (DCoP). He works closely with the Dehcho First Nations to determine the best possible permafrost thaw adaptation and mitigation strategies based on the Dene language (Dene Zhatie) and traditional knowledge. He is also working with other DCoP community-based investigators toward the development of a research framework rooted in Dene values and traditional livelihoods. As part of this initiative, he is also co-developing with DFN partners, a regional podcast which aims to provide a forum for dialogue on climate change knowledge and adaptation, and to connect local communities with larger audiences.
Nanar is a researcher employed by the Western Arctic Centre for Geomatics (Government of the Northwest Territories) and is pursuing her PhD at Wilfrid Laurier University.

Shaghayegh (Shae) Akbarpour
Shae is a PhD student of water resources engineering based at the University of Waterloo. Her research is focused on modelling the climate warming induced evolution of land covers in discontinuous permafrost regions of northwestern Canada. She uses these modelling outcomes to investigate the effects of the land cover changes on the hydrological functioning of the drainage basins in these regions. Shae is also devising a land cover change model from different machine learning methodologies which can be used to predict the future evolution of land covers throughout the circum-polar region.
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.
Mason is examining the mass and energy balances of a permafrost body using geophysical, thermal, micro-meteorological and a remote sensing measurements and archived data. He is also examining how changes to these balances arising from climate warming and direct human disturbance will affect water flux and storage processes.
Kristine Haynes, as a Postdoctoral Fellow, has joined the Scotty Research Team synthesizing the long-term water level data with the aim of constructing a water balance for the site.

Ryan's Ph. D. research is focused on improving the understanding of and ability to model runoff from peat plateau-bog complexes. So far his research has identified major runoff pathways and how their importance changes with soil moisture conditions. He has also shown that recent increases in discharge from streams and rivers in the southern NWT is strongly influenced by permafrost thaw-induced land-cover change that has increased the extent of runoff contributing areas.
John's M.Sc. research at Scotty focused on the influence of permafrost thaw on mercury methylation in wetlands and streams, a subject of growing concern with local communities in the NWT. John now works with SLR Consulting (Bradford on Avon, UK) as a Land Quality & Remediation Associate.
Emily's M.Sc. research focused on snowmelt runoff processes on a peat plateau-bog complex at Scotty Creek. Specifically, she examined the impact of permafrost thaw on snowmelt runoff generation. Her work with helped to improve the understanding and ability to simulate snowmelt runoff in wetland-dominated high-Boreal environments. Emily now works as a Researcher at the Hakai Institute in British Columbia, Canada.
Elyse examined the impact of fire on snow accumulation, melt and ground thermal regimes. She used a combination of detailed energy flux measurements above and below the ground surface, and aerial remote sensing provided by cameras mounted on UAV platforms. She is now a Fire Research Analyst with the Canadian Forest Service (Northern Forestry Centre) of Natural Resources Canada in Edmonton, Alberta.
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.

He is now an Assistant Professor in the Department of Earth and Environmental Sciences, University of Waterloo and remains an important member of our research team.
Lindsay studied the hydrology of channel fens at Scotty Creek. She intensively instrumented a 700 m fen connecting Goose Lake and First Lake in the Scotty Creek basin to better understand the flux and storage of water within and from the fen. She also used the Cold Regions Hydrological Model (CRHM) to improve the understanding of the hydrological functioning of channel fens and how it can change in response to disturbance. Lindsay is now lives in California, USA where she works as a Data Analyst for Apple and Apex Systems.
Stacey's research examined the role of black spruce root networks in the redistribution of energy into and from the active layer, and the relative importance of the root network and the soil matrix in providing energy into the ground to thaw the active layer and degrade the underlying permafrost. She now works with the City of Hamilton, in Hamilton, Ontario.

Her research focuses on the relationship between black spruce canopy cover and permafrost thaw rates and patterns. This research aims to further understand how northern landscapes are transitioning in response to a warming climate. Jessica hopes to combine disciplines of ecology and hydrology to predict future trajectories of northern forests.
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!
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.
