Northwest Territories Power Corporation Twin Gorges Aquatic Effects Monitoring Plan and Sediment and Erosion Management Plan
Principal Investigator: Byrne, Geraldine
Licenced Year(s): 2013
Summary: The Aquatic Effects Monitoring Plan (AEMP) and Sediment and Erosion Management Plan (SEMP) are requirements under water license MV2011L0002 issued by the Mackenzie Valley Land and Water Board (MVLWB). The objective of the AEMP is to monitor and identify potential short-term, long-term and cumulative changes throughout the Taltson River aquatic environment. The objective of the SEMP is to identify...


Erosion of carbon from high-latitude peatlands: Isotopic insight into fluvial transfer in the Mackenzie River Basin
Principal Investigator: Hilton, Robert G
Licenced Year(s): 2017 2013 2011 2010 2009
Summary: The objectives of this research project are to correct for fossil particulate organic carbon (POC) input to the Mackenzie River, and to determine the loci of peatland organic carbon (OC) erosion and flux to the fluvial system. WATER VELOCITY TRANSECT At each sampling location, an Acoustic Doppler Current Profiler (ADCP) will allow the research team to determine bathymetry, water velocity trans...


Flux of sediment-associated chemical elements in rivers draining to the Arctic Ocean
Principal Investigator: Bogen, Jim J
Licenced Year(s): 2010
Summary: The objective of this research is to estimate the modern and historical fluxes of sediment- associated chemical elements to the Arctic Ocean and their relationships to natural and man-induced changes in sediment yields and sediment sources and if possible, predict the impact of future climate changes on the fluxes. The study will include sampling of overbank sediments from floodplains and del...


Regional Geochemistry Survey, Mackenzie Mountains NWT
Principal Investigator: Falck, Hendrik
Licenced Year(s): 2007
Summary: The objective of this study is to collect stream silts on first order streams on a regional basis at a density of one sample every 13 Km2 across the target area. Heavy mineral concentrate samples will be collected at a density of one sample every 25 km2. The samples will be dried, labeled and shipped to various laboratories for cataloging and analysis. A team of 2 field workers would use a heli...


Active Layer Monitoring Network in the Mackenzie Valley
Principal Investigator: Nixon, Frederick M
Licenced Year(s): 2008 2007 2006 2005 2004 2003 2002 2001 2000 1999 1998 1997 1996 1995 1994 1993 1992 1991 1990
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...


Biological Studies of Waters along the Proposed Mackenzie Gas Pipeline Route - Inuvialuit Settlement Region
Principal Investigator: Evans, Marlene S
Licenced Year(s): 2009 2008 2007 2006
Summary: This study is designed to fill science gaps in Environment Canada’s understanding of the structure and functioning of the aquatic environment potentially impacted by various aspects of the Mackenzie Gas Project. While data collected during the Environmental Impact Assessment studies (carried out in conjunction with the proposed construction and operation of the Mackenzie Gas Pipeline) are relative...


IPY-SCARF: International Polar Year - Study of Canadian Arctic River-delta Fluxes
Principal Investigator: Lesack, Lance
Licenced Year(s): 2008 2007
Summary: The Arctic Ocean receives much higher river inflows than other ocean basins and this has major implications for sea-ice formation, for nutrient supply to the base of aquatic marine foodwebs, and for optical properties of ice-free areas and ice-pack margins via fluxes of dissolved organic matter and riverine particles. The Beaufort Shelf is strongly influenced by Mackenzie River outflows. However, ...


Biological Studies of Waters Along the Proposed Mackenzie Gas Pipeline Route - Gwich'in Settlement Region
Principal Investigator: Evans, Marlene S
Licenced Year(s): 2009 2008 2007 2006
Summary: This study is designed to fill science gaps in Environment Canada’s understanding of the structure and functioning of the aquatic environment potentially impacted by various aspects of the Mackenzie Gas Project. While data collected during the Environmental Impact Assessment studies (carried out in conjunction with the proposed construction and operation of the Mackenzie Gas Pipeline) are relative...


Norman Wells Straw Bales and Reflective Surface Test
Principal Investigator: Graburn, Larry
Licenced Year(s): 2006 2005
Summary: The objective of this project is to test the thermal properties of straw bales and reflective surfaces for use on permafrost slopes along a potential pipeline route in the Mackenzie Valley. These materials might be used in conjunction with or as alternatives to wood chips to protect the exposed slopes from surface erosion and reduce the rate of thawing. In mid-February 2006 a bulldozer and brush c...


2005 Spring Break-up Watercourse Investigation Program in the Gwich'in Settlement Area
Principal Investigator: Graburn, Larry
Licenced Year(s): 2005 2004
Summary: This research is part of an aerial reconnaissance program to study spring breakup at the major watercourse crossings along the proposed pipeline right-of-way from the Deh Cho region in the south to the Inuvialuit Settlement Region in the north. The resea...
