Summary: Climate change is expected to have the greatest impacts in northern regions. Permafrost degradation is a likely outcome of warming temperatures. As temperatures increase and permafrost begins to melt, there is likely to be significant impacts on aquatic communities as nutrients and contaminants accumulated in permafrost are released into lakes. This study will examine the impact of permafrost degr...

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 the seabed mapping program is to conduct a regional survey of the Beaufort Shelf over the next four years. Ice scouring processes, benthic habitats, abandoned artificial islands, pingo-like features, gas seeps, seafloor foundation conditions, sub-sea permafrost and coastal stability will be investigated. The Coast Guard vessel CCGS Nahidik will be used to collect seabed sedi...

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 2005 terrestrial studies in the Inuvialuit Settlement Region (ISR) will include vegetation classification, rare plant surveys, and landform, soil and permafrost investigations. The studies will be conducted by three- or four-person crews supported by helicopter and based in Inuvik. A local assistant will be hired as part of each survey team. Air calls from a helicopter will be used to map ...

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...

Summary: Since the 1970's, the oil and gas industry has drilled at least 19 exploratory wells in the Kendall Island Bird Sanctuary (KIBS), but there is a shortage of field data describing environmental conditions at the well-sites and drilling-mud sumps. In Marc...

Summary: The overall objective of this research is to construct and test predictive computer models that show the evolution of lowland permafrost landscapes. Surveys and radiocarbon dating of drained basins will be undertaken and canoe-based surveys will determin...
