Summary: The objectives of this research project are to: 1. map and assess changes in the distribution and composition of forest and peatland ecosystems due to climate changes; 2. estimate carbon storage (and variation) in boreal to arctic ecoregions of the Mackenzie valley; and 3. assess interannual and seasonal variations and key processes controlling carbon dioxide (CO2) and methane (CH4) dynamics. ...

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...

Summary: An improved understanding of the thaw and drainage processes, and exchanges of energy and moisture that control the flow of water in the vast wetland region of Canada is needed to improve weather and climate change predictions. Large-scale experiments on soils of the Central Mackenzie River basin will be used to elucidate moisture and carbon transport processes in the active layer. Laboratory base...

Summary: Little is known about glacier activity in the Ragged Ranges. Glaciers are the source of the South Nahanni River, which supplies moisture to the entire Nahanni ecosystem. The research will help complete existing databases and aid the Intergovernmental Panel on Climate Change. Regional assessments will help estimate the costs of climate change and inform debates on Kyoto targets and the proposed exp...

Summary: It is important for researchers to improve their understanding of the sensitivity of slopes to disturbance from development, especially in the context of progressive climate warming. Additionally, predictions of the impacts of climate change on the terra...

Principal Investigator: Lamoureux, Scott F
Licensed Year(s): 2002
Summary: The objective of the research is to supplement and extend instrumental climatological and hydrological records in the NWT using dendrochronology (tree-ring) and varved lake sediment analysis. Transportation to the site will be by charter aircraft from Fo...

Licensed Year(s): 2001
Summary: The research team will be flown from Norman Wells to the base camp at Moose Horn River by helicopter. Moves to fly camps (Stoneknife River and Black Wolf Creek) will also be made by helicopter. The camp will consist of one sleeping tent per team member and one cooking tent. The research team will walk to data collection sites on foot. Data collection will consist of measuring rocks with a rule...

Summary: Soil (at seven depths) and air temperature data are recorded by data loggers. These loggers are programmed to collect data every 3 hours on the hour. The sites are visited twice a year to reprogram the loggers. In addition, active layer depth and subsidence are also recorded during the fall visit. Researchers will collect this data in order to determine the effect of climate change on the envi...

Licensed Year(s): 1993
Summary: The research in Nahanni National Park includes the setting up of programs to monitor water depth and vegetational changes along the river. Changes in water depth influence the ability of navigating the river, especially in areas of rapids, and has implications on the level of expertise required by visitors travelling the river. Monitoring vegetation along the river will provide information about...

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....
