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. She is examining potential differences in long-term water storage across the variations in landscape of the Scotty Creek watershed. A future goal is to broaden her mercury cycling research to investigate the influence of permafrost thaw and subsequent landscape and hydrological changes.
Brenden is an MSc student researching permafrost presence beneath treed bogs at Scotty Creek. He will be combining ground penetrating radar (GPR) and electrical resistivity tomography (ERT) to determine permafrost extent and will be examining the hydrological characteristics of these features. Brenden hopes to improve the understanding of permafrost formation and degradation in zones of discontinuous permafrost.
Mikhail is a PhD student researching the impacts of permafrost thaw on runoff processes and hydrologic connectivity in the Hudson Bay Lowlands (HBL) in Ontario’s Far North. By comparing thaw impacts in discontinuous and continuous permafrost portions of the HBL, Mikhail hopes to improve our understanding of permafrost thaw in world’s third largest contiguous wetland complex.
Angela's is a Master's of Science Geography student focusing on the effects of a 1986 seismic line on the peatland wetland area at Scotty Creek. Currently 3 bogs have been selected for their variability for her study of these effects. Through measurements of water levels, moisture, biodiversity, temperature, snow melt, water movement, and others the differences in values will outline the effects of the line.
Gabriel is a Research Technician based at the University of Montreal for the Changing Arctic Network (CANet). His expertise is on hydrometerological instrumentation, including eddy co-variance systems.
Julie received her Ph.D. in 2011 at the Helmholtz Centre for Environmental Research (UFZ), Leipzig, Germany. After a first PostDoc at that institute, she moved to University of Waterloo in September 2016 and joined our research programme. Her expertise is in modelling and computational analyses like parameter estimation, sensitivity analysis and uncertainty analysis. She is further strongly interested in the development of robust and widely applicable computer codes.
Joelle is pursuing her M.Sc. at Western University. She is generating a permafrost plateau model using FEFLOW to simulate thaw and its interactions with groundwater.
Caren is studying how forest fires alter the physical and hydraulic properties of peat and how these changes affect both the quantity and quality of runoff.
Bhaleka is studying how climate in the Fort Simpson (NWT) region has changed over the last half century. Her work on how the changing climatic conditions have influenced stream flows is an important complement to other work within the team that is focussed on how permafrost thaw has affected steam flows.
Élise is pursuing her PhD at the University of Waterloo in hydrological and thermal modelling and plans to apply her skills to improve the understanding of the rate and pattern of permafrost thaw at Scotty Creek. She is a modeller, but also loves to be in the field. That makes her an even better modeller.
Lindsay is studying 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 uses 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.
Elyse is examining the impact of fire on snow accumulation, melt and ground thermal regimes. She uses a combination of detailed energy flux measurements above and below the ground surface, and aerial remote sensing provided by cameras mounted on UAV platforms.
Alex MacLean is the full-time Research Technician in the Department of Geography and Environmental Science at Laurier. He makes a very important contribution to the Scotty team by helping to prepare students for the field, and assisting with technical aspects of the project. Alex joins us in the field at Scotty whenever he can.
Emily's M.Sc. research is focused on snowmelt runoff processes on a peat plateau-bog complex at Scotty Creek. Specifically, she will examine the role of shrub and tree canopies on controlling the spatial distribution of melt energy over the heterogeneous complex. She is working with the Raven hydrological model to improve the understanding and ability to simulate snowmelt runoff in wetland-dominated high-Boreal environments.
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.
Dr. Laura Chasmer
Laura Chasmer (PDF) is interested in climate change; remote sensing; long-term ecosystem change; energy and mass (CO2, H2O) exchanges; discontinuous permafrost; forestry; scaling; ecosystem models. Her research is focused on the influence of canopy structure and ground surface topography on energy balance and scalar fluxes within northern boreal and discontinuous permafrost ecosystems. To do this, she uses a range of remote sensing technologies (including airborne and terrestrial lidar systems), hydrometeorological equipment, and in situ measurements. Dr. Chasmer is now at the University of Lethbridge in Alberta, but she remains an important member of our research team.
At Scotty Creek, Tyler studied the influence of tree-canopy, shrub-canopy and ground surface properties on the rate and spatial pattern of seasonal active-layer thaw. His work helped to improve our understanding of and ability to predict areas of preferential permafrost thaw. Tyler is now a Senior Planning and Program Advisor with Alberta Environment.
Dr. Justin Adams
Justin played a leading role in the Consortium for Permafrost Ecosystems in Transition (CPET), which examines permafrost-thaw impacts on water resources and ecosystems in the southern Northwest Territories, northeastern British Columbia, and northern Ontario. Justin is now a Post-Doctoral Fellow at the University of Guelph.
Michael's M.Sc. research focussed on the hydrological impacts of seismic lines in the wetland-dominated zone of discontinuous permafrost. Specifically, he examined permafrost degradation and regeneration processes along seismic lines, and the hydrological consequences of these processes. Michael is a Geophysicist with GHD Engineering and remains a very active member of the Scotty research team.
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.
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.
Dr. Fereidoun Rezanezhad
Fereidoun's PDF focussed on developing new analytical methods of measuring the physical and hydraulic properties of peat soils using X-ray computed tomography. This research led to improved algorithms for predicting mass and energy flows through organic soils. 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.?
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.
Nicole is the first student of the SCRS, which makes her a "Scotty Pioneer". Her PhD research shed new light on coupled runoff and thaw processes which led to important advances in understanding and modelling the hydrology of the study region. Nicole is now a Senior Hydrologist with Ecofish Research, Campbell River, Bristish Columbia.
