Summary: The overarching research goal of this project is to determine what conditions facilitate tree range expansion across the western Canadian boreal-tundra ecotone. Using a biogeographical, multi-trophic level approach, the research team aim to determine: 1. how multi-trophic level species composition changes across the tundra and which conditions dictate these changes; and, 2. the constraints, dri...

Principal Investigator: Kasook, Davonna C
Licensed Year(s): 2018 2017
Summary: The objective is to compare differences in snow depth, density and morphology of a heavily forested site and a tundra site. The Principal Investigator (PI) will study the effect landscape (forest vs. tundra) has on seasonal snow pack evolution and physical properties (density, temperature, snow grain morphology, and stratigraphy) of the snowpack. These results will be compared to historical data (...

Summary: The goal of this research is to understand how landscape processes influence the quantity and quality of soil carbon in the Mackenzie Delta Region. Particular attention will be paid to the depth distribution of soil carbon and how it is affected by differences in vegetation and soil forming processes. Key environmental differences that will be examined include forest vs. tundra and delta vs. uplan...

Summary: The objectives of this study are to quantify the surface-atmosphere methane emissions over large areas, and to analyze the influence of different surface and vegetation characteristics on large area methane emissions (process understanding). The research team proposes to measure methane fluxes between the tundra and the atmosphere by airborne eddy covariance, a micro-meteorological method. Flux...

Principal Investigator: Lantz, Trevor C.
Licensed Year(s): 2011 2010
Summary: There are two objectives associated with this research project. The first is to establish vegetation and permafrost monitoring sites in the Inuvialuit Settlement Region (ISR) and the Gwich’in Settlement Area (GSA). The establishment of these permanent monitoring sites will improve our understanding of base-line environmental conditions in the region. The second goal for the 2011 monitoring season...

Principal Investigator: Spencer, Lee A
Licensed Year(s): 2009
Summary: This licence has being issued for the scientific research application No.1072. The researchers will collect plant fossils from the Miocene Ballast Brook and Pliocene Beaufort Formations (Ballast Brook River), Banks Island. They will transport the specimens to Southern Adventist University, Collegedale, Tennessee, USA, for DNA processing and analysis. A final report will be submitted to Aurora...

Principal Investigator: Miller, Glenn D
Licensed Year(s): 2008
Summary: The objective of this research is to identify and document valued vegetation components in the vicinity of proposed winter activities. Each selected site will be assessed for important vegetation components, such as the potential for: rare plants and vegetation communities. The research will include photo documentation and visual observations to characterize each site for vegetation features. Inf...

Principal Investigator: Wunderlich, Nicole B
Licensed Year(s): 2008
Summary: The objective of this study is to determine if the plant community composition of seeded and unseeded disturbances in the Mackenzie Delta is similar to the undisturbed tundra. This comparison may help determine best practices of recovery for native vegetation to use in future oil and gas projects in the region. The vegetation data will be collected using non-destructive methods including species p...

Summary: The active layer is the earth overlying permafrost that thaws from the surface and re-freezes each year, and it responds to climate change. Active layer thickness influences vegetation and soil conditions, potentially influencing hunting, forestry, etc. and it’s, thickness, texture and moisture content affects foundations. Changes in the active layer and thaw depth can contribute to slope instabil...

Principal Investigator: Kanigan, Julian
Licensed Year(s): 2007 2006
Summary: The Mackenzie Delta is sensitive to both climate warming and human development. This project will contribute to a better understanding of ground temperatures in the Mackenzie Delta and will provide a baseline from which to assess future changes and cumulative impacts. Ground temperatures will be collected from the southern, central and outer delta regions. In the summer, about 30 boreholes (l...
