Project Description: 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 thawing. As well the researchers will describe the structural characteristics of the frozen ground, identify thaw unconformity and analyze the frequency of mass movement activity and the effects of thawed material flow to the creek hydrology. The researchers will camp on site and will hire 2 local guides.
