Controls on carbon and nutrient cycling in arctic tundra
Principal Investigator: Grogan, Paul
Licenced Year(s): 2016 2015 2014 2013 2012 2011 2010 2009 2008
Summary: The goal of this research over the next five years is to substantially advance the understanding of how Canadian arctic tundra ecosystems function, and therefore how they are likely to be affected by perturbations such as climate change, resource development and extraction, and atmospheric pollution. Specifically, the research team will focus on the impacts on vegetation due to warmer summer tempe...


2009 Baseline Studies for Avalon Ventures Ltd. Proposed Thor Lake Rare Earth Metals Project - Surface Water Hydrology
Principal Investigator: Lennie-Misgeld, Peter
Licenced Year(s): 2011 2010 2009
Summary: This licence is being issued for the scientific research application no. 982. The objective of this research is to characterize the surface water hydrology at the Thor Lake site and vicinity for at least one hydrologic year. The baseline study is being conducted to aid Avalon Ventures in assessing potential environmental effects of its activities and having adequate environmental information to...


Variability and Change in the Canadian Cryosphere - Tundra Information Transferability Study
Principal Investigator: Walker, Anne E
Licenced Year(s): 2008
Summary: Environment Canada plans to measure snow depth, snow density and snow water equivalent (water storage in the snowpack), as well as lake ice thickness and structure for comparison with microwave radiometer measurements. Researchers have started to use microwave data from satellites for assessing snow water equivalent (SWE). Field tests to investigate the use of microwave sensors indicate that SW...


Variation of near-surface ground temperatures in spruce forests, Mackenzie Delta, Northwest Territories
Principal Investigator: Kanigan, Julian
Licenced Year(s): 2007 2006
Summary: An understanding of near-surface ground temperatures will provide a baseline to assess change and identify sensitive areas. The objective of this project is to determine the variation of near-surface ground temperatures within the Mackenzie Delta. Investigations have identified four spruce forest communities in the delta based on composition: spruce-alder-bearberry, spruce-feathermoss, spruce-crow...


Environmental Soil Chemistry at Abandoned Drilling Mud-Sumps in the Kendall Island Bird Sanctuary, Mackenzie Delta Region
Principal Investigator: Biggar, Kevin
Licenced Year(s): 2006 2005
Summary: Since the 1970s, the oil and gas industry has drilled at least nineteen exploratory wells in the Kendall Island Bird Sanctuary. Observations at associated drilling mud-sumps have been made; however, there remains a paucity of field data describing site conditions. It is also appreciated that construction of the proposed Mackenzie Valley pipeline will stimulate the development of Niglintgak and Tag...


Hydrological Studies, Mackenzie Delta Region
Principal Investigator: Marsh, Philip
Licenced Year(s): 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2006
Summary: The project includes studies on the rates and processes controlling snow accumulation, snowmelt, water flux through snow, and exchange of water between snow cover, active layer and permafrost. The effect of snow or soil temperature regime and vegetation types on runoff processes, evaporation processes, and development of physically-based, predictive models of snowmelt runoff will also be studied i...


The effect of Great Slave Lake on air and surface temperatures in peatlands near Yellowknife
Principal Investigator: Karunaratne, Kumari C
Licenced Year(s): 2005 2004 2003
Summary: The objective of this project is to determine the effect of Great Slave Lake on air and surface temperatures, and permafrost conditions. Each of the study sites along the Ingram Trail that were instrumented with air and surface temperature sensors during summer 2003 will be revisited in 2005. The data loggers will be downloaded, relaunched and the batteries will be replaced at each instrumentati...


Snow accumulation/runoff in high latitude permafrost basins
Principal Investigator: Marsh, Philip
Licenced Year(s): 2005 2004 2003 2002 2001 2000 1999 1998 1997 1996 1995 1994 1993 1992 1990
Summary: The primary objective of this project is to improve understanding of the changes in water and energy in northern regions, and to develop improved computer models of these processes. The Trail Valley Creek, Hans Creek, and Zed Creek sites will be accessed...


Mass Balance of Arctic Glaciers
Principal Investigator: Koerner, Roy M
Licenced Year(s): 2008 2007 2006 2005 2004 2003
Summary: This study monitors glacier health and climatic change in the high Arctic and is part of an ongoing program that began in the early 1960s. It is also part of a larger program studying climate change. Base camp is located at the Polar Continental Shelf...


Spring Melt Hydrological Investigations at Daring Lake, N.W.T.
Principal Investigator: English, Michael C
Licenced Year(s): 2003 2002 2001 2000
Summary: Tthe objective of this study is to continue research examining the hydrological and energy budget of small arctic esker lake basin during the spring melt period. The intent of this research is to understand the relationship between the energy budget and changes in soil moisture, rates of evapotranspiration, and changes in water discharge from a small tundra basin underlain by permafrost. Transpo...
