Climate change and postglacial paleoenvironmental history of peatlands in the Mackenzie Delta area
chercheur principal:
Année(s) de permis: 1993 1992
Résumé: 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
chercheur principal:
Année(s) de permis: 1993
Résumé: 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
chercheur principal:
Année(s) de permis: 1997 1996 1995 1994 1993 1992 1991 1989
Résumé: 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
chercheur principal:
Année(s) de permis: 1994 1992 1991 1990 1988
Résumé: 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....


Peat Plateau Collapse and Climate Change
chercheur principal:
Année(s) de permis: 1992
Résumé: The research will examine permafrost-containing peat plateaus that have burned during severe fires to determine the features of subsidence (decrease) and the rate of subsidence....


Architecture and Construction Technique in the North
chercheur principal:
Année(s) de permis: 1992 1991
Résumé: The Researcher will continue to investigate the relationship between the architectural and technical aspects of buildings and severe northern climate....


International Cryosol Tour
chercheur principal:
Année(s) de permis: 1991
Résumé: 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....


Enivronmental Studies of the Ice-Bearing Region in Canadian Arctic
chercheur principal:
Année(s) de permis: 1990
Résumé: 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....


Reconstruction of Holocene Environments
chercheur principal:
Année(s) de permis: 1990
Résumé: 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....
