chercheur principal:Dyke, Larry Année(s) de permis:
1999
Résumé:
The goal of this research is to examine landslides on the slopes along the Mackenzie Valley, so that researchers can better understand their causes and the effect climate change will have on the landscape. Field work will be carried out between Wrigley and Inuvik along the Mackenzie River, with some access along the Dempster Highway. Tree increment cores will be used to determine tree age and dat...

Résumé:
This project is intended to determine the amount by which fluids disposed of in abandoned oil well drilling mud disposal pits (sumps) have migrated into surrounding frozen ground. The sumps are not presently considered to pose any kind of environmental hazard but they do offer a unique opportunity to determine the effectiveness of permafrost as a containment for waste fluids. The main activity i...

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...

1990
Résumé:
The Researcher will follow detailed studies by the GSC on permafrost distribution along retreating coasts at the north end of Richards Island, and adjacent areas of sediment accumulation to find out how quickly permafrost was re-established. This study will extend further westward to determine the adjustment of permafrost to the rapid sedimentation occurring there....

1988
Résumé:
To place temperature probes using a water jet to measure temperatures beneath a 2 km long spit at the north end of Richards Island to determine if the accumulation of these sediments has influenced the distribution of permafrost....

1987
Résumé:
To establish the distribution of permafrost in the tidal zone of an emerging Arctic Coast. To install 2 thermistor cables to a depth of 10-15 m. on the beach one km. west of the settlement of Cambridge Bay, Victoria Island....

1985
Résumé:
To re-occupy sites established on Melville Island for the measurement of frost heaving of bedrock. These sites consist of arrays of survey markers which are periodically resurveyed using a theodolite and stadia rod....
