Summary: This licence is being issued for the scientific research application no. 978. The objectives of this research are to: 1) Monitor permafrost conditions in the Mackenzie Delta region; 2) examine freeze-back of the active layer and associated strength properties of freezing soil; 3) examine the influence of shrub removal on frozen ground and snow conditions at abandoned drilling-mud sumps; 4) inve...

Summary: This study investigates the distribution and amount of near-surface ground ice in sediments of the Mackenzie Delta area. The research team will consist of Steve Kokelj (Carleton University - principle researcher) and Doug Joe (Inuvik). The proposed fieldwork will begin in Inuvik in April, with the main part of the field work being carried out from 30 July to 20 August. In April, the research te...

Principal Investigator: Lacelle, Denis
Licensed Year(s): 2000
Summary: 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 ...

Summary: For this on-going study, measurements such as maximum depth of thaw and soil surface movements recorded after the previous visit, will be collected. Monitoring apparatus will be reset this season. Sites in the Mackenzie Delta, from Tsiigehtchic to Tuktoyaktuk will be visited in April. Most sites from Fort Simpson to Tuktoyaktuk will be occupied during the summer....

Summary: To determine the maximum size of treeline tree species in a burned and unburned valley in the Caribou Hills, the mass of standing trees on different slopes and aspects will be estimated and related to the energy input. In 1992 the plots prepared in 1990 and planted and seeded in 1991, will be revisited and measurement of growth for the second growing season will be taken....

Summary: The Researchers will continue work to understand how the climate influences the activity of processes that move sediment down hillsides. The aim of the project is to establish links between climate and the activity of geomorphic processes so that predictions can be made about the possible impact of any climate change....

Principal Investigator: MacLean, Brian
Licensed Year(s): 1993 1990
Summary: The Researcher and his team will be travelling through Hudson Strait by research ship to take samples of the deposits and sediments in the Strait. They will be investigating the history and conditions of the area based on the sediments record in order to detail the late glacial and post glacial conditions of the Strait....

Summary: To measure the energy exchange and rate of headwall retreat of a number of ground ice slumps....

Principal Investigator: Lewkowics, Antoni G.
Licensed Year(s): 1984
Summary: To measure the energy exchange, rate of headwall retreat and water balance of a number of ground slumps. This is a continuation of a study began in 1983....

Principal Investigator: Bliss, Lawrence
Licensed Year(s): 1978
Summary: (1) Study of growth paterns of evergreen shrubs in a low shrub tundra, evaluate winter roads and salt water spills at well sites. (2) Life history study of the grass, Alopecurus alpinus, a study of the cold hardiness of certain high arctic plants and a study of natural ground slumps....
