Hydrological Remote Sensing
Principal Investigator: Berg, Aaron A
Licenced Year(s): 2017
Summary: This research has two main objectives: 1) to monitor the spatial variability of soil moisture at the scale of a Soil Moisture Active Passive (SMAP) 36km pixel centered around the Trail Valley Creek (TVC) watershed; and, 2) to evaluate the current soil moisture algorithms and products currently utilized by SMAP. To achieve the first objective, the research team will install soil moisture monit...


A Mass-Energy Analysis of Permafrost and Vegetation Change Across a Mackenzie Mountain Treeline Ecotone: 1944 to 2017
Principal Investigator: Kershaw, Geoffrey GL
Licenced Year(s): 2017
Summary: The objectives of this project are to assess changes in ice rich permafrost landforms and plant community composition across a treeline ecotone and relate those larger shifts to specific physically based estimates of energy-mass budget for such features. The distribution of permafrost and vegetation both vary through time and space across the treeline, and while changes in one will affect the othe...


The effects of wildfire on diverse aquatic ecosystems of the NWT
Principal Investigator: Tank, Suzanne E
Licenced Year(s): 2017 2016
Summary: The objective of this study is to determine the effect of fire on water quality within the southern NWT landscape. The research team will work across the Taiga Plains and Taiga Shield ecoregions. Differences in landscape between these regions will affect the catchment response to fire. The team will also target catchments with variable permafrost extent, and wetland/lake coverage. The research ...


Kennady North Diamond Project
Principal Investigator: Panayi, Damian
Licenced Year(s): 2017 2016
Summary: The objective of this research is to document existing environmental conditions surrounding the Kennady North Diamond Project. Hydrology studies include the measurement of selected lake inflow and outflow and stream profile through field surveys, and installation of data loggers to continually monitor lake levels through the open-water season. Hydrology studies will be initiated during the spri...


Biogeochemistry of Lakes in the Mackenzie Delta
Principal Investigator: Lesack, Lance
Licenced Year(s): 2017 2016 2015 2014 2010 2009 2007 2006 2005 2004 2003 2002 2001 2000 1999 1998 1997 1996 1995 1994 1993
Summary: The objective of this research project are to: 1) improve the understanding of microbial carbon-processing in Mackenzie Delta lakes and how it is affected by the changing water levels; and, 2) to decipher the impact of water level changes on the ability of the Mackenzie Delta to affect riverine nutrient flow to the ocean. This work will help resolve what drives microbial communities in Mackenzi...


Permafrost in the western Arctic
Principal Investigator: Kokelj, Steve V
Licenced Year(s): 2017 2016
Summary: The primary objectives of this research are: 1) to develop and test new methods of monitoring permafrost landscape change; 2) to investigate the impacts of natural and human disturbance on permafrost terrain and the ground temperature conditions in natural environments and in communities; and, 3) to assess the physical and chemical characteristics of permafrost. To achieve the objectives the r...


Impacts of permafrost thaw on hydrology and water resources
Principal Investigator: Quinton, William L.
Licenced Year(s): 2017
Summary: Understanding the ecology and hydrology of ecosystems with thawing permafrost is a major challenge. To meet this, the research team will develop new knowledge on the eco-hydrology of the major ecosystems (i.e. bogs, fens, peat plateaus) needed to develop new science-based tools to predict the future supply for the next 50 years. The specific scientific objectives are to: 1) develop fundamental kno...


Hydrology of High Latitude Watersheds
Principal Investigator: Marsh, Philip
Licenced Year(s): 2017 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2006
Summary: The objectives of this project are: 1) to develop improved understanding of, and ability to predict, snowcover formation and melt, as well as stream discharge in northern regions, 2) to consider the integrated effect of climate on vegetation, snow, permafrost, streamflow, and lakes, and 3) to develop improved predictive tools or models. These will allow a better understanding of the impact of clim...


Investigations of the water cycle and hydrological processes of the subarctic Canadian Shield
Principal Investigator: Spence, Christopher
Licenced Year(s): 2017 2016 2012 2011 2010 2009 2008 2007
Summary: It is the objective of this research to determine the water cycle processes acting in watersheds that could affect the streamflow response and water chemistry of Taiga Shield streams. The proposed work will take place within a research basin framework. The proposed watershed, the upper reaches of Baker Creek, is a typical Canadian Shield stream that drains 150 km2 into Great Slave Lake. There ...


City of Yellowknife Gold Project
Principal Investigator: Campbell, Joseph W
Licenced Year(s): 2017 2016 2015 2014
Summary: Follow-up on exploration activity associated with theMackenzie Valley Land and Water Board land use permit MV2014C0005 on Terrax Minerals Inc. City of Yellowknife Gold Project. Work would include initial environmental baseline work, and expansion of research programs to establish sufficient study for possible future Environmental Impact Assessment of potential mine development if exploration activ...
