Tyler Williams (B.Sc., Simon Fraser) began his M.Sc. programme in September, 2010. His research at Scotty Creek, NWT is focussed on understanding the hydrological and ecological consequences of linear disturbances such as seismic lines and winter roads. The density of linear disturbance at Scotty Creek is about 6-times greater than the natural drainage density. Moreover, where the tree-canopy is removed (i.e. during seismic exploration), the underlying permafrost degrades or disappears, allowing for the hydrological connection of previously isolated terrain units. Tyler's research will provide guidance for reducing the environmental impact of future seismic exploration.
