Investigating the Effects of Winter Overland Travel in sub-Arctic Boreal Forest
chercheur principal: Kanigan, Julian
Année(s) de permis: 2012 2011
Résumé: In discontinuous permafrost of the southern NWT, cleared transportation corridors, such as seismic lines, have recently been associated with permafrost loss, increased soil moisture and vegetation changes. Permafrost loss can lead to ground subsidence, infrastructure instability and the release of stored carbon into the atmosphere. The research team will test whether seismic lines can be construc...

Old Canadian National Railbed and Highway 5 Soil Sampling, Hay River area
chercheur principal: Kanigan, Julian
Année(s) de permis: 2010 2009
Résumé: The objective of this research is to investigate metals levels, particularly lead and zinc, and hydrocarbons in soils near the old CN railbed to Pine Point mine, and Highway 5 to the Tamerlane R-190 advanced exploration site. Specific objectives are to 1) Determine levels of metals, particularly lead and zinc, and hydrocarbons on and adjacent to the old CN railbed; 2) Establish levels of metals, p...

Examining Spatial and Temporal Variation of Ground Temperatures in the Mackenzie Delta, Northwest Territories
chercheur principal: Kanigan, Julian
Année(s) de permis: 2007 2006
Résumé: The Mackenzie Delta is sensitive to both climate warming and human development. This project will contribute to a better understanding of ground temperatures in the Mackenzie Delta and will provide a baseline from which to assess future changes and cumulative impacts. Ground temperatures will be collected from the southern, central and outer delta regions. In the summer, about 30 boreholes (l...
