Summary: In discontinuous permafrost of the southern NWT, cleared transportation corridors, such as seismic lines, have recently been associated with permafrost loss, increased soil moisture and vegetation changes. Permafrost loss can lead to ground subsidence, infrastructure instability and the release of stored carbon into the atmosphere. The research team will test whether seismic lines can be construc...

Summary: The objectives in 2011 are to draw together multiple sources of information to: (1) examine change in lake area in this ecoregion, (2) quantify the type and amount of habitat loss or modification, (3) investigate whether recent changes are part of a longer-term cycle and evaluate the causes of this change, (4) determine a way to document and integrate local and traditional knowledge of physical an...

Summary: In the Gwich’in Settlement Region, residents of Fort McPherson have identified the unusual size of the mega-slumps on the Peel Plateau as a serious concern to both water quality and aquatic ecosystem. In addition to research oriented objectives relevant to understanding cumulative effects of mega-slump development on the land and water of the Peel Plateau, the project team will pursue establishing...

Summary: The overall objective of this research is to improve our knowledge on present-day food webs/productivity in small Arctic pond/lake systems in order to better predict changes that could occur under changing climate. The methodology described below pertains to all research activities related to this research component dealing with fish. All other research activities related to this work were revi...

Licensed Year(s): 2009 2008 2007 2006
Summary: The objective of this field work is to better understand the movement behaviour of the landslides in the region. The Geological Survey of Canada’s research group lead by Dr. Baolin Wang has been conducting landslide research in the region since 2004. This is the final year of the project. The previous permits have expired. However, there is a need to make a follow up trip to the various landsli...

Summary: The objectives of this research are: • To provide baseline knowledge of permafrost and terrain conditions (specifically ground temperature and permafrost active layer thickness) and improve characterization of terrain sensitivity in the Mackenzie Valley. • Monitor ground temperature and active layer to detect changes in permafrost conditions resulting from surface disturbance or climate change a...

Principal Investigator: Wallenius, Tuomo H
Licensed Year(s): 2009
Summary: This licence is being issued for the scientific research application No.1103. The research objective is to study the occurrence of forest fires in Northern Canada during the past 200 years. They are especially interested in large scale averages and changes in the estimated fire return intervals/annually burned proportions of the landscape. Specific research questions are: 1. How often for...

Summary: This licence is being issued for the scientific research application no. 978. The objectives of this research are to: 1) Monitor permafrost conditions in the Mackenzie Delta region; 2) examine freeze-back of the active layer and associated strength properties of freezing soil; 3) examine the influence of shrub removal on frozen ground and snow conditions at abandoned drilling-mud sumps; 4) inve...

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...

Licensed Year(s): 2006
Summary: The Mackenzie Gas Pipeline will cross more than 600 tributaries of the Mackenzie River, ranging from small (< 1 m) vegetated swales to large rivers. All construction methods, with the exception of trenchless drilling, will disturb the bed and banks of the rivers they cross. Fish habitat use and distribution has not been studied in sufficient detail. Fish will be captured and identified for spec...
