Effects of permafrost disturbances on terrestrial and aquatic ecosystems, Banks Island, NWT, Canada
chercheur principal: Lacelle, Denis
Année(s) de permis: 2015
Résumé: Thaw slumps are one of the most dramatic thermokarst features in permafrost regions. The number of thaw slumps on Banks Island has more than tripled in recent decades and it is likely that this change is altering terrestrial and aquatic ecosystems. This multidisciplinary research project investigates the short- (1960s-present day) and long-term (Medieval Warm Period to today) impacts of permafrost...


The cumulative impacts of rapid environmental change in the northwestern NWT: Investigating the impacts of mega-slump disturbances on terrestrial and aquatic ecosystems in the lower Peel watershed, NW
chercheur principal: Lacelle, Denis
Année(s) de permis: 2013 2012
Résumé: This is a multidisciplinary project involving communities, governments and academic researchers. The goals are to: 1) inventory and track broad scale changes in landscape disturbances; 2) determine the impacts of natural and anthropogenic disturbances on the physical and chemical characteristics and ecology of streams and rivers; 3) determine disturbance thresholds relevant to the health of stream...


Distribution and Habitat Use of Sensitive Fish Species along the Mackenzie River Valley
chercheur principal: Mochnacz, Neil
Année(s) de permis: 2006
Résumé: 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...


Long-term ecological and geomorphological investigations in the alpine tundra of the Mackenzie Mountains, N.W.T.
chercheur principal: Kershaw, G. Peter
Année(s) de permis: 2018 2017 2016 2015 2014 2012 2010 2009 2008 2007 2006 2005 2004 2003
Résumé: This study is to monitor the environmental impacts of disturbances caused by the Canol Project and to measure the effects on permafrost of climate change. The Canol disturbance studies have been underway since the late 1970's and the permafrost studies since 1990. This is year 15 of a 20-year study. Access during the summer is via the Yukon along the Canol Road through Macmillan Pass. Beyond...


Mackenzie Valley Landslide Geotechnical Investigations
chercheur principal: Nichol, Susan L.
Année(s) de permis: 2005
Résumé: The objective is to improve knowledge about landslides in the Mackenzie Valley. The results of this study will enable better environmental impact assessments and help to reduce environmental impacts related to the construction and operation of the proposed Mackenzie Valley pipeline. As well, the results will have a broader application to a wide range of future development activities in the region....


Modified Phase II Environmental Site Assessment O-35 Wellsite
chercheur principal: Miller, Samantha
Année(s) de permis: 2003
Résumé: The objectives of this assessment are to conduct a site investigation to evaluate potential environmental impact associated with daily facility operations associated with the O-35 wellsite. In August 2002, an Environmental Site Assessment was conducted....


Modified Phase II Environmental Site Assessment N-01 Wellsite
chercheur principal: Miller, Samantha
Année(s) de permis: 2003
Résumé: The objectives of this assessment are to conduct a site investigation to evaluate potential environmental impact associated with daily facility operations associated with the N-01 wellsite and to set up background concentrations of parameters for the lea...


Modified Phase II-III Environmental Site Assessment F-36 Wellsite
chercheur principal: Miller, Samantha
Année(s) de permis: 2003 2002
Résumé: The objectives of this assessment are to conduct a soil investigation and remediation associated with the flare stack at the Paramount Resources Ltd. F-36 Wellsite. In August 2002, a modified Phase II Environmental Site Assessment was conducted. The bas...


Preconstruction biophysical site assessment (wildlife, vegetation) of potential well locations and flow line options within the Significant Discovery Area, and post-construction vegetation and permafrost monitoring on the Cameron Hills Gathering System
chercheur principal: Hong, Tom
Année(s) de permis: 2002
Résumé: A pre-construction biophysical site assessment will focus on wildlife and vegetation. The proposed well-sites will be examined on foot, and the flowlines walked to document vegetation types, including rare species if present. Main vegetation types will b...


Vegetation Survey for the Ikhil Gas Development
chercheur principal: Sutor, Greg
Année(s) de permis: 1997
Résumé: Vegetation communities along the pipeline route and over other parts of the Project area would be provisionally mapped from aerial photographs. A field survey would be undertaken with an emphasis on identifying rare plants. The study area is in the Caribou Hills IBP site 4-9, which was in part proposed because of its rare flora. July is an optimum time for a single survey. Also transect sampling ...
