Mass Balance of Arctic Glaciers and Arctic Pollution
chercheur principal: Koerner, Roy M
Année(s) de permis: 2008 2007 2006 2005 2004 2003
Résumé: The objectives of this ongoing research project are: (a) to monitor climate change by measuring the changing volume of the ice cap and maintaining an automatic weather station, and (b) to monitor air and snow pollution by sampling snow and sending it to be analyzed. Based out of the Polar Continental Shelf Project in Resolute Bay, NU, two personnel will fly by Twin Otter to the ice cap, and liv...


Lithogenic elements and isotopes in peat cores as markers of Holocene climate changes in the Mackenzie River valley
chercheur principal: Outridge, Peter M
Année(s) de permis: 2007
Résumé: The objective of this research is to reconstruct climate change information as well as recent industrial mercury and lead pollution histories for Inuvik and the lower Mackenzie River valley. To determine the above, a core sample of peat will be taken from a peat bog located near Inuvik, and analyzed for elements and dusts deposited from the air over the last 7,000 years. The site will be a...


Tundra Northwest 1999
chercheur principal: Karlqvist, Anders
Année(s) de permis: 1999
Résumé: The overall goal of the expedition Tundra Northwest 1999 is to study geographic variation of terrestrial and freshwater ecosystems of the tundra. By using the CCG icebreaker Louis St. Laurent for transport and as a scientific platform the the expedition route will include a longitudinal gradient from Baffin Island to the northern coast of Alaska and a latitudinal gradient through the Canadian Arc...


Ice Core Analysis and Glacier Mass Balance
chercheur principal: Koerner, Roy M
Année(s) de permis: 1995 1992 1991
Résumé: The researchers will measure the snow mass at fixed locations on each of four ice caps. This will be compared to similar measures taken last year. Ice and snow samples will also be collected for later analysis for pollutants. Ice cores will be drilled from the Penny Penny Ice Cap at several locations....
