Summary: The objective of this research is to measure high and low voltage patterns hundreds of kilometers above the ground and out into space along the Earth's magnetic field lines. This information is critical to personnel in space and to maintenance of the satellite telecommunications. Radar transmitting and receiving electronics will be installed in a small building with an antenna array outside. A ...

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...

Summary: The impact of climate change on forest ecosystems in the Mackenzie Delta is being studied using dendrochronology. Earlier studies indicate a negative relationship between tree growth and summer temperatures. Summer temperatures may be exceeding the physiological threshold of northern trees or perhaps the trees are drought stressed. Manual and automatic dendrometers will be used to measure tree gro...

Summary: The objectives of this study are to quantify the frequency and magnitude of ice jams in the Mackenzie River Delta, including the hydroclimatic conditions controlling their occurrence and associated floods, develop a hydraulic model of it, and investigate the importance of deep scour holes in the Mackenzie River. This study is an expansion of previous research conducted in 2004. Ice jamming has ...

Licensed Year(s): 2006 2005
Summary: The main goal of this research is to use lake sediment records to examine changes in weather conditions and river discharge in the western Canadian Arctic during the past 2000 years, which will aid in understanding current conditions and forecasting future conditions. The research team will reach the study location by airplane from Resolute, Nunavut, and will be on site from late May to early ...

Principal Investigator: Evans, Kevin
Licensed Year(s): 2002
Summary: The issues to be addressed in the emissions and air impact assessment portion of the project include: 1) adequacy of baseline emissions, air quality, meteorological and climatological data, as well as air quality and deposition monitoring data, for the B...

Principal Investigator: CLARK, Ian D.
Licensed Year(s): 2000 1999
Summary: Data will be collected that can help to predict climate of the near future and determine the impact of temperature change on northern hydrology. The investigator will attempt to better understand how methane-producing bacteria function giving us a better understanding of their feedback on climate change. The research area is a quarry along the Dempster highway east of Campbell Lake. This site w...

Summary: Snow plays an important role in northern ecosystems. It accounts for a large portion of the years total precipitation and therefore when its melts in the spring it is responsible for significant flood, for increased soil moisture upon which plants are reliant for summer growth, & for refilling lakes and ponds. Snowcover stores atmospheric input of solutes, nutrients, & pollutants during the wint...

Principal Investigator: Jacoby, Gordon C.
Licensed Year(s): 1994 1989
Summary: The researcher will take 5 mm diameter increment core samples from old-aged trees growing near the tree line. This sampling is not harmful to the trees. At two sites the researcher will sample about 10 trees. The samples are processed to produce ring-width and wood- density data for each annual ring. This data will then be statistically compared to meteorological data to make estimates of past cl...

Principal Investigator: Landhaeusser, Simon M.
Licensed Year(s): 1992 1991 1990
Summary: The Researcher and his team will seed and plant plots prepared in 1990. They will determine the germination rate, establishment and the annual growth of the seedlings. The measurements will be related to the energy input which influences these microsites....
