Present and Past Hydrology, Ecology and Climate of the Mackenzie Basin Deltas
chercheur principal: Wolfe, Brent BBW
Année(s) de permis: 2007 2006 2005 2004 2003 2002
Résumé: Summer 2005 field activities will focus on continuing multi-year studies of the modern hydrology and ecology of the Slave River Delta. The aim of this research is to improve knowledge of changes in lake water balance and chemistry and the subsequent responses of aquatic plants over seasonal and inter-annual time-scales under varying climatic and hydrological conditions. Overall, this information...

Holocene Environment Change Across Treeline, Mackenzie Delta Region
chercheur principal: Pisaric, Michael FJ
Année(s) de permis: 2008 2007 2006 2005
Résumé: There are three main parts in the researchers' project: 1) investigating changes in vegetation cover in the Inuvik region during the past 10,000 years using fossil pollen and stomata preserved in lake sediment; 2) investigating the importance of disturb...

Investigations of ground ice development in sediments of the Mackenzie Delta area.
chercheur principal: Burn, Chris R
Année(s) de permis: 1997 1996 1995 1994 1993 1992 1991
Résumé: The purpose is to collect samples of ground ice and to measure air, ground and lake temperatures. We use the information to help understand how the permafrost in the area has changed in the last few thousand years, in order to determine what might happen in the future....

Palynology (Mackenzie Valley Global Change), study of the climatic change along the Mackenzie River and on the Arctic Islands.
chercheur principal: Jette, Helene
Année(s) de permis: 1995 1993 1992
Résumé: The researcher will sample a variety of lakes (some 50 lakes altogether) around Inuvik. A hole, approximately 8 inches in diameter, will be bored through the ice in each lake. Using an Ekman sampler, lake bottom sediments (mud) will be collected for analysis in the lab. The researchers will get to each of the lakes bt helicopter and spend approximately 15 to 20 minutes at each lake....

Late Quaternary Glacial and Climate History on Southern Baffin Island
chercheur principal: Miller, Gifford H.
Année(s) de permis: 1994 1993 1991 1990 1989 1987
Résumé: The researchers will obtain sediments from lakes near Cape Dyer to document past climatic conditions. Vegetation and lake water chemistry data will also be collected in order to collect information about the current environment: this data can be compared to historic data. Finally, the inner Frobisher Bay area will be surveyed for data about past sea levels and glacial landforms. This research w...

Study of bio-indicators of environmental change in arctic lakes
chercheur principal: Smol, John P
Année(s) de permis: 1994 1993 1992
Résumé: The researchers plan to take samples of lake water and lake sediments from a variety of sites in the region. From these samples, information will be collected about the water chemistry, microscopic organisms present in the lakes, and changes in the region's past environmental and climatic conditions....

Overbank sediment patterns on the Mackenzie Delta
chercheur principal: Pearce, Cheryl M.
Année(s) de permis: 1993 1992 1991 1990
Résumé: The researcher will continue her long-term study on the physical features of the Mackenzie Delta. Hydrocarbon development, water volume and course changes, and climate change could have major effects on the water and sedimentation patterns of the delta. This study will increase knowledge of sedimentation patterns, shoreline erosion and their relationships with vegetation....
