Distribution and Habitat Use of Sensitive Fish Species along the Mackenzie River Valley
Principal Investigator: Mochnacz, Neil
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...


Enhancement of Permafrost Monitoring Network and collection of baseline terrain information in Mackenzie Valley Corridor - Deh Cho Region
Principal Investigator: Smith, Sharon S
Licensed Year(s): 2006
Summary: The Geological Survey of Canada maintains a network of active layer and permafrost temperature monitoring sites in the Mackenzie region in order to document the response of permafrost conditions to climate change. Gaps exist in the network in the permafrost zones north of Norman Wells, the Mackenzie Delta region, and on shorelines and coastlines. Enhancement of the network is essential to provide ...


Community-Based Monitoring Camps
Principal Investigator: LeTourneau, Michele
Licensed Year(s): 2008 2006
Summary: The community-based monitoring camp was created by Diavik to involve Aboriginal Peoples of communities affected by the mine site. People are concerned with effects on fish, water and caribou. Dust from the mine falls out on lichen and water, which are then consumed by caribou and fish. People will gather information about Diavik and environment-related issues and provide input and recommendations ...


Enhancement of Permafrost Monitoring Network and Collection of Baseline Terrain Information in the Mackenzie Valley Corridor - Gwich'in Settlement Area
Principal Investigator: Smith, Sharon S
Licensed Year(s): 2006
Summary: Gaps exist in the Mackenzie monitoring network in the permafrost zones north of Norman Wells, the Mackenzie Delta region and shorelines and coastlines. Enhancement of the network is essential to provide baseline information for developments such as pipelines, highways and power lines, and to assess the impact of such development and/or climate change on the environment. In this project, temperatur...


Determination of PBDEs in Canadian North Landfill Leachate and Soils
Principal Investigator: Danon-Schaffer, Monica N
Licensed Year(s): 2006
Summary: Given the threats of polybrominated diphenyl ethers (PBDEs) and their widespread appearance in marine mammals and far northern communities, identifying the sources of these compounds and of various PBDE congeners in air, water and soil are of utmost importance. Potential ecological and human health risks, and increasing concentrations of PBDEs in the environment require early implementation of con...


WO Diamond Project
Principal Investigator: Hamm, Sharleen
Licensed Year(s): 2006
Summary: In view of Peregrine Diamonds Ltd.’s move to advance the DO-27 kimberlite pipe of the WO Diamond Project to the pre-feasibility assessment phase, this project is proposed to collect baseline data that would contribute to an Environmental Assessment in subsequent years. Gartner Lee Ltd has been contracted to undertake field sampling, which will consist of examining surface water quality; hydrology;...


Sediment Transport Processes in Canyon Creek, Sahtu Settlement Region
Principal Investigator: Rempel, Laura L
Licensed Year(s): 2006 2005
Summary: The aim of this study is to characterize sediment transport processes, including bed scour and fine sediment deposition, in a sub-arctic stream intersected by the proposed Mackenzie Gas Pipeline. The specific objectives of the study are: characterization of surface and sub-surface bed sediment texture for all habitat types; measurement of bed scour depth and transport distance of sediment due to ...


Enhancement of Permafrost Monitoring Network and Collection of Baseline Terrain Information in the Mackenzie Valley Corridor - K'asho Got'ine District, Sahtu Settlement Area
Principal Investigator: Smith, Sharon S
Licensed Year(s): 2006
Summary: Twelve sampling sites in the K'asho Got’ine District of the Sahtu Settlement Area have been selected for this project, with preferred locations chosen near existing winter roads and the C.N.T. trail for continuous site accessibility and to minimize disturbance to the environment. One or two boreholes up to 20 m in depth will be drilled at each site in order to capture local environmental variabili...


Environmental Soil Chemistry at Abandoned Drilling Mud-Sumps in the Kendall Island Bird Sanctuary, Mackenzie Delta Region
Principal Investigator: Biggar, Kevin
Licensed Year(s): 2006 2005
Summary: Since the 1970s, the oil and gas industry has drilled at least nineteen exploratory wells in the Kendall Island Bird Sanctuary. Observations at associated drilling mud-sumps have been made; however, there remains a paucity of field data describing site conditions. It is also appreciated that construction of the proposed Mackenzie Valley pipeline will stimulate the development of Niglintgak and Tag...


Hydrological Studies, Mackenzie Delta Region
Principal Investigator: Marsh, Philip
Licensed Year(s): 2023 2022 2021 2020 2019 2018 2017 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2006
Summary: The project includes studies on the rates and processes controlling snow accumulation, snowmelt, water flux through snow, and exchange of water between snow cover, active layer and permafrost. The effect of snow or soil temperature regime and vegetation types on runoff processes, evaporation processes, and development of physically-based, predictive models of snowmelt runoff will also be studied i...
