Northwest Territories Power Corporation Twin Gorges Aquatic Effects Monitoring Plan and Sediment and Erosion Management Plan
chercheur principal: Byrne, Geraldine
Année(s) de permis: 2013
Résumé: 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
chercheur principal: Hilton, Robert G
Année(s) de permis: 2017 2013 2011 2010 2009
Résumé: 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...

Active Layer Monitoring Network in the Mackenzie Valley
chercheur principal: Nixon, Frederick M
Année(s) de permis: 2008 2007 2006 2005 2004 2003 2002 2001 2000 1999 1998 1997 1996 1995 1994 1993 1992 1991 1990
Résumé: 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...

IPY-SCARF: International Polar Year - Study of Canadian Arctic River-delta Fluxes
chercheur principal: Lesack, Lance
Année(s) de permis: 2008 2007
Résumé: 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, ...

Geomorphological and hydrological research on valley formation in Arctic and subarctic environments
chercheur principal: Schunke, Ekkehard
Année(s) de permis: 2000 1994 1992 1990
Résumé: The researcher will measure discharge, run-off velocity, sediment load, dissolved load and microclimate parameters (air and ground temperatures, relative humidity, evaporation, precipitation and radiation) in small valleys of James Creek. They drive to the location in a 3/4 ton truck which is parked in an abandoned quarry near the road. They walk to their data collection sites. The observations...
