The objective of this research is to model runoff from wetland basins to help determine the influence of climate warming on northern water resources.
Fieldwork will commence with snow surveys. Sensing equipment (water level recorders, rain gauges, radiation sensors) will be installed and stream flow measurements will be taken following snowmelt. Water samples will be gathered from runoff areas....

2005 Résumé:
The objective of this project is to test the thermal properties of straw bales and reflective surfaces for use on permafrost slopes along a potential pipeline route in the Mackenzie Valley. These materials might be used in conjunction with or as alternatives to wood chips to protect the exposed slopes from surface erosion and reduce the rate of thawing. In mid-February 2006 a bulldozer and brush c...

Résumé:
This is a study of retrogressive thaw sumps produced by the exposure and melting of massive ice in continuous permafrost (Richardson Range, NWT). These sumps are recently occurring and presumably a result of global climate change. This research will recognize retrogressive thaw slumps that have massive ice, identify the type of massive ice (glacier buried or segregated) and measure the rate of ...
