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 ...

Summary: Objectives of the research are two-fold. First is to estimate structure and growth of forest stands in northwestern Canada by applying a stand reconstruction technique. Second is to examine the relationship between climate change in the Arctic region and the patterns of forest biomass growth during the past century. The research team also measure currently occurring growth and carbon dynamics of f...

Principal Investigator: Schertzer, William M.
Licensed 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...

Principal Investigator: Rouse, Wayne R
Licensed 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...

Principal Investigator: Karunaratne, Kumari C
Licensed 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...

Principal Investigator: Walker, Donald A
Licensed 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...

Principal Investigator: Nixon, Mark

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...

Principal Investigator: Melling, Humfrey
Licensed 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...

Principal Investigator: Morewood, Dean
Licensed 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...

Principal Investigator: Woo, Ming-ko
Licensed 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....
