Structure, Carbon Dynamics, and Silvichronology of Boreal Forests
Principal Investigator: Osawa, Akira
Licenced Year(s): 2017 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2006 2005 2004 2003 2002 2001
Summary: The objectives of the 2015 field work are two-fold: one is to collect data in jack pine and in lesser extent black spruce forests on annual movement of organic matter and carbon; the other is to continue the study of stand development and its relationship to environmental factors (a discipline called ‘silvichronology’). For the former objective, the research team will continue measurement of the ...


Modelling Temperature and Heat Fluxes of Great Bear Lake
Principal Investigator: Schertzer, William M.
Licenced Year(s): 2009 2008
Summary: This licence is being issued for the scientific research application No.1100. The four main objectives of this research are: 1) to conduct observations on Great Bear Lake to measure meteorology, heat fluxes, and physical limnological components; 2) to model the thermal structure of Great Bear Lake under current climate and climate changed conditions; 3) to quantify the variability in the meteor...


Modelling of Evaporation and Heat Balance of Great Bear Lake
Principal Investigator: Rouse, Wayne R
Licenced Year(s): 2006 2005 2004
Summary: The objectives of the research are to: pursue temperature and energy balance studies on Great Bear Lake; determine if Great Bear Lake’s climate behaves like that of Great Slave Lake, or if its unique geographical position and physical attributes make it distinctive; and to explore the temperature structure of the atmosphere above Great Bear Lake and link this with heat and moisture exchanges betwe...


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...


Biocomplexity of frost-boil ecosystems
Principal Investigator: Walker, Donald A
Licenced Year(s): 2006 2005 2004 2003
Summary: The goal of this project is to understand the complex linkages between biogeochemical cycles, vegetation, disturbance and climate across the full summer temperature gradient in the Arctic in order to better predict ecosystem responses to changing climate...


Active Layer Monitoring Network in the Mackenzie Valley
Principal Investigator: Nixon, Mark
Licenced Year(s): 2008 2007 2006 2005 2004 2003 2002 2001 2000 1999 1998 1997 1996 1995 1994 1993 1992 1991 1990
Summary: This ongoing survey examines permafrost so as to better understand how the active layer varies locally and regionally and how it will respond to environmental change, including but not restricted to climate change. The research team will survey from For...


Ice Thickness Topography Study -Beaufort Sea
Principal Investigator: Melling, Humfrey
Licenced Year(s): 1996 1995 1994 1993 1992 1991 1990
Summary: The researchers will retrieve untended sonar instruments operating beneath the sea that were positioned in April 1994. After servicing, these instruments will be re-deployed at the same locations to continue the observations for another year. A survey of water water properties will be collected at about 20 sites in the offshore and observations made using a lowered probe to 1500 m depth or to t...


Temperature relations and interactions of arctic woolly-bear caterpillars and their insect parasitoids
Principal Investigator: Morewood, Dean
Licenced Year(s): 1994 1993
Summary: Surveys will be conducted in order to: (1) document the life stages of the caterpillars (e.g., eggs, larvae, pupae and adults) during the summer; (2) count the number of caterpillars killed by insect `parasites' or parasitoids; and (3) document the timing of the insect parasitoids's life cycle. Finally, since temperature affects growth, experiments with different temperatures will be use to exami...


Hydrological modelling for a permafrost site and arctic snow accumulation and melt
Principal Investigator: Woo, Ming-ko
Licenced Year(s): 1994 1993
Summary: This on-going study attempts to find out how permafrost affects the groundwater, streamflow and levels of water in wetlands. Measurements such as soil moisture, rainfall, ground and air temperatures, and water level will be taken. This research will help to determine how climatic change affects permafrost and water bodies in the Arctic....


Effects of predicted climate change on high arctic plants
Principal Investigator: Henry, Gregory H.R.
Licenced Year(s): 1994 1993 1992
Summary: As part of a long-term study, we will continue to monitor the field experiments set up at Alexandra Fiord on Ellesmere Island which examine the effects of climate warming on high arctic plants. Small enclosures have been placed on top of the plants in order that the growing conditions such as temperature and moisture can be altered and their influences on the plants examined. This study is part ...
