Summary: The objectives of this project are to define the impact of snow depth, surface vegetation, and soil characteristics on spatial and temporal variations in active-layer freeze-back in the low arctic tundra east of the Mackenzie Delta. The duration of freeze back will be determined from the ground temperatures measured at the top of permafrost. This temperature only declines at the site when the ac...

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 researchers want to learn about the ground conditions at the site by drilling up to 69 boreholes to depths ranging from 16 to 50 metres. They want to find out how thick the active layer is and find any transitions between frozen and unfrozen ground;...

Summary: The general objective of the program is to obtain information with respect to subsurface conditions at the site by drilling up to fifty boreholes to depths ranging from sixteen to twenty metres. The specific objectives of the program are to characterize...

Summary: Changes in the ground due to uplift, associated with the growth of a pingo, and sideways movements due to the growth of ice wedges, will be measured. Air, ground, and lake water temperatures will be measured, in order to find out how the ground is responding to climatic variation. The reseach team will also return to Paulatuk, to continue studies Dr. Mackay began there 50 years ago. Travel to s...

Principal Investigator: Wolfe, Stephen A
Licensed Year(s): 1999
Summary: The objective of the present study is to assess the impact of recent warming, including the warm summer of 1998, on active layer thicknesses and slope stability in the Mackenzie Delta, N.W.T. and Yukon North Slope. The main mode of transportation will be by helicopter (206L) and by boat to transport people. The helicopter will be based out of Inuvik with a fuel cache at Tuktoyaktuk. The helicop...

Summary: To conduct a low level (2000 ft. above groud level) a high level (30,000 ft. A.G.L.) aerial surveys of the reindeer rangeland. Ground truthing will also take place along with collection of plants, soil and water made to complete the study....
