Understanding and predicting the impacts of permafrost thaw on water resources and ecosystems
Principal Investigator: Quinton, William L.
Licenced Year(s): 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2006 2005 2004 2003 2001
Summary: Understanding the integrated eco-hydrological behaviour of ecosystems in the context of thawing permafrost is a major challenge. To meet this, the research team will measure the present surface and near-surface water supplies and their inter-annual variability assuming a condition of no permafrost thaw. The team will also develop new knowledge on the eco-hydrology of the major ecosystems (i.e. bog...


Improving Habitat Connectivity to Enhance Productive Capacity of Arctic Freshwater Ecosystems
Principal Investigator: Tonn, William
Licenced Year(s): 2014 2013 2012 2011 2010 2009
Summary: The objectives of this project are: 1) to study the freshwater ecology, hydrology, and hydraulics of small lakes and streams in the Lac de Gras basin before habitat modification; 2) to monitor the changes in ecosystem productive capacity resulting from habitat modifications designed to increase habitat connectivity and fish passage; and 3) to assess the effectiveness of such habitat modifications...


Ecological Assessment Field Work for Lue Túé Sulái (the Five Fish Lakes) Candidate Cultural Conservation Area
Principal Investigator: Haas, Claudia A
Licenced Year(s): 2012 2011
Summary: This project is to fill gaps in ecological information on a Candidate Protected Area while it makes its way through the NWT Protected Areas Strategy (PAS) process. This information will be used by the working group to make recommendations on final boundary and management planning for the area. The study will be done at the same time as a study on mercury in fish being conducted by the Dehcho F...


Sensitivities of high-latitude lakes to climatic & development disturbances
Principal Investigator: Prowse, Terry D
Licenced Year(s): 2008 2007 2006 2005
Summary: The objective of this study is to develop a hydro-ecological model for small Arctic lakes to assess the vulnerability of their ecosystems to disturbances, such as climate change or water withdrawal. To quantify geochemical loadings to lakes, a model is being developed by monitoring lakes and their contributing catchment (surface water flow). A climate station will be set up at 2 - 6 sites to mo...


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, ...


2006 -2007 Biophysical and Reconnaissance Studies in the Inuvialuit Settlement Region
Principal Investigator: Hawkins, Jim R.
Licenced Year(s): 2007
Summary: Several environmental and engineering studies were conducted between 2001 and 2006 to assess a proposed pipeline in the Mackenzie Valley. These studies will continue in 2007 and 2008. Route and site reconnaissance will be by helicopter, and crews will land at selected sites based on observations made during the flight. Reconnaissance surveys of road-water crossings will be performed. Pipeline-...


2006 - 2007 Biophysical and Reconnaissance Studies in the Gwich’in Settlement Area
Principal Investigator: Hawkins, Jim R.
Licenced Year(s): 2007
Summary: Several biophysical and engineering studies on the feasibility of a pipeline in the Mackenzie Valley have been conducted, and will continue in 2007. Local knowledge, scientific research, and existing technical information are being used to develop a knowledge base for environmental protection plans, engineering design and regulatory processes. Route and site reconnaissance will be by helicopte...


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: Researchers will evaluate the spatial variability of nutrient chemistry during the snowmelt period within the drainage network of the tundra stream ecosystem. Evaluation of the controls on nutrient chemistry and community metabolism in streams withing the borel forest/tundra ecotone through the measurement of algae and organic matter in the stream. Evaluation of the potential role of Mackenzie De...


Implications of climatic change on water-based recreational activities in Nahanni and Jasper National Parks
Principal Investigator: Staple, Tamara
Licenced Year(s): 1993
Summary: The research in Nahanni National Park includes the setting up of programs to monitor water depth and vegetational changes along the river. Changes in water depth influence the ability of navigating the river, especially in areas of rapids, and has implications on the level of expertise required by visitors travelling the river. Monitoring vegetation along the river will provide information about...


University field course on the arctic environment
Principal Investigator: Howarth, Phil
Licenced Year(s): 1993
Summary: The three professors from the University of Waterloo will lecture the students on the subjects of ecology, geology and climate and conduct field trips in the vicinity of Igloolik and Iqaluit. The students will select topics to study while in Igloolik: their studies will be assessed and assigned a grade....
