Evaluating the environmental impacts of permafrost mega-disturbances along the Dempster Highway, NWT
Principal Investigator: Kokelj, Steven V
Licenced Year(s): 2014 2013 2012 2011 2010
Summary: The objective of this research project is to document the extent of ecological change in impacted stream basins draining the eastern slope of the Richardson Mountains and to determine the mechanisms of slump initiation and stabilization. This study will focus on the Stoney Creek catchment, which runs parallel to the Dempster Highway and empties into the Peel River at Fort McPherson, NT. The catchm...


Population abundance and vital rates of fish harvested from lakes along the Mackenzie Valley pipeline route – Loon Lake 2005
Principal Investigator: Toyne, Melanie J
Licenced Year(s): 2005
Summary: The proposed Mackenzie natural gas pipeline route crosses Loon River, which connects Loon Lake to the Mackenzie River. It is important to collect information on fish species in Loon Lake to compared with after the proposed pipeline is built to determine if any changes have occured. All field crew transported to Loon Lake via North-Wright twin otter floatplane. Crew will set nets to catch fish an...

Principal Investigator: Fortier, Louis
Licenced Year(s): 2004 2003 2002
Summary: The Canadian Arctic Shelf Exchange Study (CASES), a major international effort under Canadian leadership, aims to understand the biogeochemical and ecological consequences of sea ice variability on the Mackenzie Shelf (Beaufort Sea) and provide the infor...


Studies on the past, present and future ecological impact on Canadian northern boreal forest and arctic ecosystems due to mining activities, shown at the Great Slave Lake area, Northwest Territories, Canada
Principal Investigator: Steinecke, Karin
Licenced Year(s): 1998 1997
Summary: The project will focus on understanding, analyzing and evaluating the reactions of the northern boreal forest ecosystems in the Great Slave Lake region due to man made stress of mining, settlement and connecting activities. The project will try to develop some general conclusions, statements and model systems. The research team (2 persons) will come from Europe to Yellowknife by plane. The base wi...


Reconstruction of forest structure and function in Canadian Taiga
Principal Investigator: Osawa, Akira
Licenced Year(s): 1998 1997
Summary: The research team consisting of forest ecologists, will go to Wood Buffalo National Park by air. A rental vehicle will also be used in the field. Most activities will consist of re-measuring jack pine stands that were examined in 1992. Various kinds of measuring tapes and a pole are used to obtain data. A few stands will be studies by taking stem samples for examination of tree rings and tree g...
