The biophysical significance of groundwater and ground ice processes in high arctic permafrost systems

The far North represents one of the most challenging research environments in Canada, not only does it's natural systems behave differently than elsewhere, but the obstacles to Arctic fieldwork (both scientific and logistical) are enormous. The Arctic is also one of the most important global systems driving ocean and atmospheric circulation. It is also widely recognised as "the canary in the coal mine" for global climate change. There are recent indications that Arctic climates are changing faster than predicted only a few years ago. Extreme environments like the Arctic provide important clues in our understanding about the limits of physical and biological processes on Earth. Lessons learned in Earth's Polar Regions are being used to develop a better understanding of neighboring planets like Mars.
