Sediment Transport Processes in Canyon Creek, Sahtu Settlement Region
chercheur principal: Rempel, Laura L
Année(s) de permis: 2006 2005
Résumé: The aim of this study is to characterize sediment transport processes, including bed scour and fine sediment deposition, in a sub-arctic stream intersected by the proposed Mackenzie Gas Pipeline. The specific objectives of the study are: characterization of surface and sub-surface bed sediment texture for all habitat types; measurement of bed scour depth and transport distance of sediment due to ...


Particle Dynamics on the Mackenzie shelf (CASES sub-project)
chercheur principal: Walker, Tony R
Année(s) de permis: 2005 2004
Résumé: The Beaufort Sea shelf is very shallow and the Mackenzie River, which sends freshwater, nutrients, and particles onto the shelf, may have a large influence on its productivity. The researchers would like to study the effects of the river in transporting particles to the shelf by measuring the types of particles, how fast they sink, and how easily they are stirred from the bottom. They would also ...


Laminated lake sediments from the Canadian high arctic
chercheur principal: Bradley, Raymond S.
Année(s) de permis: 1994
Résumé: The researchers plan to measure weather conditions in the Sophia Lake area, together with measurements of stream flow and sediment movement in the lake. This information will help us to understand what controls the transfer of sediments from the land to the lake, and how this transfer is dependent on year-to-year changes in the weather. By examining the lake sediments, we may be able to reconstr...


Impact of climatic change on earth surface processes, Fosheim Peninsula, Ellesmere Island
chercheur principal: Lewkowicz, Antoni G
Année(s) de permis: 1994 1993 1992 1991 1990 1988 1987
Résumé: The aim of this ongoing research is to establish links between climate and the movements of soil. By collecting this type of data, it may be possible to determine the effect that climate changes may have on the movements of soil down slopes, into rivers and eventually into the sea....


Beaufort Sea Coastal Zone Processes
chercheur principal: Solomon, Steven M
Année(s) de permis: 2000 1999 1997 1996 1995 1994 1993 1992
Résumé: As part of the Northern Oil and Gas Program (NOGAP), the Geological Survey of Canada will investigate shallow sediment types, sediment content in ice and under-ice water currents in the Canadian Beaufort Sea. This will be done by sampling and surveying using hand-held equipment and current meters (placed under the ice). This study will help to determine the role of ice in transporting sediments ...


Coastal and Nearshore Sediment Dynamics Atkinson Point Area, Tuktoyaktuk Peninsula, NWT
chercheur principal: Hequette, Arnaud
Année(s) de permis: 1993 1992 1991
Résumé: The researcher and his team will survey beach profiles using an electronic level, survey shallow lagoons and nearshore zones, collect nearshore sediment samples and deploy current meters in the nearshore zone and in a shallow lagoon....


Sedimentation in the Mackenzie Delta and Beaufort Sea Coast
chercheur principal: Hill, Philip R.
Année(s) de permis: 1994 1993 1992
Résumé: The purpose of this project is to understand how the Mackenzie Delta and adjacent coastal regions have developed over the last 18,000 years, since the last glaciation affected the region. The project will includes investigating the sub-surface development of the delta and studying the processes by which sediment supplied by the river is transported to the continental shelf and coastal waters....
