Summary: The climate and numerous field reports indicate that permafrost should be continuous in the Mackenzie Delta. However, the most recent permafrost map in the Atlas of Canada classifies the delta as having discontinuous permafrost. Yet, no extensive fieldwork covering the entire delta has ever been realized. Unfrozen conditions beneath the ground, near shifting channels, have been recognized by vario...

Summary: Sand, gravel and crushed stone are valuable geological resources, collectively known as aggregates. They are essential bed, foundation and building materials. The presence of massive ice in aggregate deposits results in a series of resource management problems, particularly for the oil industry and its contractors who rely on local granular deposits as building material. From an environmental pers...

Summary: The objective of this research is to establish the abilities of the radar method to detect vertical land deformation compared to traditional methods. Researchers will measure the topography of a target area in both June and August. During those months, researchers will also capture radar images of the same area. The topographical measurements will be compared to the radar images to determine the e...

Summary: The objective of the research is to produce estimations of the reduction in sea ice in the ISR. Eight aerial surveys are planned for approximately May 1, 14, 31, June 14, 28, July 5 and 15 (weather and aircraft availability dependent). Each survey will b...

Summary: The western Canadian Arctic coast is one of the most rapidly changing coastlines in the world and among the most vulnerable to climate change. The causes of this vulnerability have been studied over the past decade. This project involves monitoring coast...

Summary: Arctic clouds are dominant on average covering 40 to 60% of the skies over the Arctic ocean. They exert a large influence on the radiation balance in the Arctic, where climate change effects are predicted and observed to be largest in the northern hemisphere. The FIRE III field project will use in-situ measurements obtained using instrumental aircraft, in combination with concurrent satellite dta,...

Summary: Given the vast size of the N.W.T., it is very difficult to accurately measure the amount of water that is made available from snow (called snow water equivalents or SWE). A variety of agencies have collected data from climate stations and satellites and this data can be used to estimate SWE. This study will involve taking measurements of snow on the ground and comparing these measurements to th...

Summary: The Researcher will continue to determine what density of trees is necessary for detection by the satellite sensors. To determine what are the densities of shrubs and herbs or dwarf shrubs and lichens that change the reflectance patterns from the understory. To determine if the thresholds in density will be sensitive enough to monitor vegetation responses to climate change in the forest to tundra ...

Summary: The Researcher and team propose to provide a better understanding of the present fluvial regime in the area and a method of assessing the effects of uncontrollable influences such as global warming and controllable factores such as hydro-electric and pipeline development....

Principal Investigator: Timoney, Kevin, P.
Licensed Year(s): 1984
Summary: Field sampling coupled with air photo interpretation are used to describe vegetation zonation. Objectives include: a) a delimitation of the subarctic forest-tundra ecotone; b) geographic variation in the vegetation, sorts, species ranges, and width and position of the forest-tundra....
