Late Quaternary hydrological and climatic history of the lower MacKenzie River basin
Principal Investigator: Beierle, Brandon
Licensed Year(s): 2002
Summary: The research team will obtain sediment cores from a series of lakes near Reindeer Station and Inuvik for the purpose of reconstructing the hydrological, climatological and geomorphic history of the lower Mackenzie River basin. The research will require fieldwork between 15 April and 25 April. Research will involve the development of a high-resolution paleoenvironmental record based on lake sedime...


Development of a Differential Frost Heave Model: Application to Patterned Ground Formation.
Principal Investigator: Peterson, Rorik
Licensed Year(s): 1998
Summary: The objective of this work is to make physical measurements of the size, shape and distribution of earth hummocks in areas where the 1968 forest fire did not occur. We are developing a mathematical model which predicts hummock size and activity based on soil properties and environmental conditions. Because hummock activity appears to be very sensitive to environmental changes, our model, coupled ...


Soil Climates of the Mackenzie Valley
Principal Investigator: Tarnocai, Charles
Licensed Year(s): 1994
Summary: Soil (at seven depths) and air temperature data are recorded by data loggers. These loggers are programmed to collect data every 3 hours on the hour. The sites are visited twice a year to reprogram the loggers. In addition, active layer depth and subsidence are also recorded during the fall visit. Researchers will collect this data in order to determine the effect of climate change on the envi...


Forest & Forest Fire Studies in the Mackenzie Delta Ecosystem
Principal Investigator: Wein, Ross
Licensed Year(s): 1994
Summary: Since fire is most wide spread agent of change in the northern forest, society should know how climatic warming will influence the force. The fire history of the Mackenzie Delta Region is known only through fire suppresion records over the past 25 years. Spot checks on the landscape have been made, but no longer record of 5-20 decades is available. Tree ring approaches will be used in this study...


Investigation of ground ice development in sediments of the Mackenzie Delta area
Principal Investigator: Burn, Chris R
Licensed Year(s): 1997 1996 1995 1994 1993 1992 1991
Summary: The researcher will continue to collect samples of ground ice and measure temperatures in lakes and ponds. This information is used to help understand how the ground heaves as it freezes in winter, and to determine the extent of soil settlement during thaw in summer. The information about lakes is used to help understand the relations between water depths and temperatures beneath the lake....


Fire, carbon budget and climate change
Principal Investigator: Wein, Ross
Licensed Year(s): 1993
Summary: The research team will be examining areas of permafrost south of Inuvik and near Hay River in order to assess the rate of loss of permafrost as a result of the warming in climate over the past twenty years. The loss in permafrost may be speeded up following a local fire. The wetlands that replace these areas of permafrost could lead to a greater production of methane (one of the gases that contr...


Climate change and postglacial paleoenvironmental history of peatlands in the Mackenzie Delta area
Principal Investigator: Vardy, Sheila
Licensed Year(s): 1993 1992
Summary: This research is part of an international project that is aimed at documenting the history of changes in the treeline during the Holocene era. While much is known about the environment and climate of this era, little is known about the development of peatlands during this time. I will collect data on peat layering, pollen and fossils in order to determine how the peatlands developed during this ...


Implications of climate change for slope stability in the Mackenzie Valley
Principal Investigator: Dyke, Larry
Licensed Year(s): 1993
Summary: In this ongoing study, the frequency and characteristics of landslides occurring in the Mackenzie Valley area are examined. I am trying to determine the roles that forest fires, climate changes and water flow in rivers play in the location and number of landslides. The field work will involve taking measurements on past landslides that include measuring permafrost features and taking core samples...


Permafrost Studies: Western Arctic Coast
Principal Investigator: Mackay, J.R.
Licensed Year(s): 1997 1996 1995 1994 1993 1992 1991 1989
Summary: This on-going research of permafrost growth involves investigations at a large lake artificially drained in 1978. The study of pingos, started in 1969, and the study of ice wedges, started in 1966, involve measurements of ice growth....


The Nature and Origin of Ground Ice in the High Arctic and Icing as a Hydrologic Component of Northern Drainage Basins
Principal Investigator: Pollard, Wayne H
Licensed Year(s): 1994 1992 1991 1990 1988
Summary: The researchers will gain a better understanding of permafrost conditions of the study area and the environmental conditions under which permafrost formed and evolved. They will also investigate icings and icing processes, since icings are a hydrologic phenomenon and their occurance has implications for recharge and runoff of drainage systems and water resource management....
