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 ...

Principal Investigator: French, Hugh
Licensed Year(s): 1993
Summary: My research is about cracks in permafrost that have been filled in with wind-blown sand. In cliffs, these filled-in crackes appear as `veins' of sand. I will record the distribution and characteristics of these veins of sand. This information may help to determine the history behind how the cracks formed and the environmental conditions of the Mackenzie Delta up to 40,000 years ago....

Summary: The Geological Survey of Canada, as part of its on-going research activities, is planning to carry out a geotechnical survey in order to improve certain techniques used in investigating permafrost and ground ice characteristics. The techniques used are shear wave seismic reflection profiling (to determine soil properties) and drilling (to determine the origin of massive ground ice bodies in the v...

Principal Investigator: Egginton, Paul A.
Licensed Year(s): 1992 1990
Summary: This year's work continues the measurement of creep (movement) of ice-rich slopes in permafrost. Landslide distribution in the lower Mackenzie Delta (Norman Wells area) is also being mapped....

Principal Investigator: Dyke, Larry
Licensed Year(s): 1992 1991 1990
Summary: The research will involve permafrost adjustment studies on the outer Delta as well as preliminary work on landslide mechanisms along the Mackenzie River between Norman Wells and the head of the Mackenzie Delta. The purpose of the work is to understand the importance of sedimentary processes in controlling the growth and disappearance of permafrost along the coast of the Beaufort Sea....

Principal Investigator: Tarnocai, C.
Licensed Year(s): 1991
Summary: This tour and the associated meetings will focus on the genesis, classification and management of permafrost soils (Cryosols) and the possible effect of climate change on these soils....

Principal Investigator: Bennett, Lorne P.
Licensed Year(s): 1991
Summary: The Researcher and his assistant will follow up research conducted at the same site between 1985-87. They will compare known rates of permafrost creep with those measured following manipulation of certain field variables (i.e. alteration of the snow cover to change the natural ground thermal regime)....

Principal Investigator: French, Hugh
Licensed Year(s): 1990
Summary: The Researchers will conduct initial exploration of potential sites for the purpose of undertaking stratigraphic and geomorphological investigations....

Principal Investigator: Fujino, Kazuo
Licensed Year(s): 1990
Summary: The Researcher and field team will conduct a geological survey and topographic traverse survey around the massive ground ice. They will take samples for ecological study and geochemical analysis....

Principal Investigator: Begin, Christian
Licensed Year(s): 1990
Summary: The research team will investigate a few localities to determine the best sites to study eolian deposits (sand dunes) and features related to permafrost degradation. Samples of granular and organic deposits will be taken....
