Ecohydrologic Impacts of Wildfire on Peatlands
Principal Investigator: Waddington, J.M.
Licensed Year(s): 2010 2009
Summary: To investigate how the amount of peat consumption during wildfire in bogs or fens (muskeg), is affected by weather, fire behaviour, and properties of the tree canopy. Researchers will manually measure various aspects of the peat, such as total peat depth and the proportion of unburned peat present in the area. Peat depth measurements will be made by driving a 2.5cm steel rod into the peat with...


Surficial Geology of Mackenzie Corridor
Principal Investigator: Duk-Rodkin, Alejandra ADR
Licensed Year(s): 2007 2006 2005 2004
Summary: This project aims to obtain a better understanding of the sensitivity of slopes to disturbance from development, especially in the context of progressive climate warming. It will also identify baseline levels for natural and anthropogenic contaminants,...


Organic Carbon Accumulation in discontinuously frozen peatlands
Principal Investigator: Robinson, Stephen
Licensed Year(s): 1996 1995
Summary: Research will be conducted in a peatland complex approximately 12 km west of Fort Simpson (4 km west of the Wrigley Road). The major component of the field work will include the collection of peat cores in both frozen and unfrozen terrain to about 1 m depth. A total of approximately 100 cores will be collected. Core holes will be approximately 15 cm wide, and will be filled to minimize terrain ...


Development of permafrost peatlands in continental northwestern Canada.
Principal Investigator: Marion, Christine
Licensed Year(s): 1995
Summary: The researchers will take and analyse duplicate peat cores collected at each of their sites. A modified Macaulay peat corer (inside diameter 5 cm) for the non frozen peat and a small diameter permafrost probe for the perennially frozen peat will be used. Analysis of the peat cores for macrofossils stratigraphy, vegitation stratigraphy and peat chemistry will be completed....


Fire regimes in the western boreal forest and post-fire dynamics of the forest: implications for forest fire management and climate change.
Principal Investigator: Wein, Ross
Licensed Year(s): 1995
Summary: The researchers will sample 200-300 forest stands in Wood Buffalo National Park and surrounding areas as well as in the Fort Simpson area. A number of measurements will be taken in each site as well as soil cores and sections of decomposing logs and snages. These will be taken to the U. of A. for analysis. In addition, sediment cores will be taken in lake sediment and/or peatlands for stratigra...


Peat Plateau Collapse and Climate Change
Principal Investigator: Wein, Ross
Licensed Year(s): 1992
Summary: The research will examine permafrost-containing peat plateaus that have burned during severe fires to determine the features of subsidence (decrease) and the rate of subsidence....


The Influence of Thermokarst Subsidence on Peatland and the Role of Climatic Change within the Discontinuous Permafrost Zone in the Southern Mackenzie Valley
Principal Investigator: Spivey, Diane
Licensed Year(s): 1988
Summary: Diane Spivey is interested in knowing why there is less permafrost now in peatbogs. First, she will be mapping areas that have thawed and collapsed. Then, she will be looking and sampling vegetation to see if the vegetation has been disturbed so that it no longer insulates the permafrost as well. Last, she will look to see how well peat retains heat and acts as an insulator. She will use this i...
