chercheur principal: Wolfe, Brent BBW
Année(s) de permis: 2007 2006 2005 2004 2003 2002
Résumé: This research program focuses on high-resolution reconstruction of past hydrology, ecology and climate of the Peace-Athabasca (PAD) and Slave River deltas (SRD) from natural archives, including lake sediments and tree rings, supported by comprehensive field-based studies of modern hydrology, limnology and aquatic ecology. The PAD and SRD have broad ecological and cultural significance and are ecos...

chercheur principal: Gajewski, Konrad
Année(s) de permis: 2008 2004 2001 1994 1993 1992 1991 1990
Résumé: This research is a study of the changes in the climate and vegetation across the Canadian Arctic for the past 10 000 years. By studying lake sediments, the researchers will determine how climate changes in the past affected the vegetation of the region....

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...

chercheur principal: Bell, Trevor
Année(s) de permis: 1993 1990 1988
Résumé: This study will provide a better understanding of permafrost conditions in the high arctic as well as the environmental conditions that lead to permafrost formation. Study sites include the Fosheim Peninsula on Ellesmere Island and May Point and Mokka Fiord on eastern Axel Heiberg Island....

chercheur principal: Overpeck, Jonathan
Année(s) de permis: 1993 1991 1989
Résumé: The goal of our ongoing project is to collect samples of mud from the bottom of several undisturbed lakes on southern Baffin Island. In the laboratory, we will then examine the chemistry, texture and fossils found in this mud in an effort to document how the environment (mainly climate) of this region has changed over the past 2000 years. We hope that this work will eventually aid efforts to imp...

chercheur principal: Retelle, Michael J.
Année(s) de permis: 1992 1991 1990
Résumé: The researchers will attempt to reconstruct climate and past environmental conditions through recovery and study of sediment cores from lakes at Taconite Inlet, northern Ellesmere Island. They will also monitor conditions under which the lake sediments are presently accumulating....

chercheur principal: Robinson, Stephen
Année(s) de permis: 1992
Résumé: Massive ice is found in exposure in some sections of the Fosheim Peninsula. The exact origin, distribution and characteristics of these ice bodies are largely unknown. Geophysical surveys will be conducted and ice and sediment samples will be taken and analyzed....

chercheur principal: Morgan, Alan
Année(s) de permis: 1991
Résumé: The Researchers will collect sediment samples. Insect fossils will be extracted and analysed. The insect communities recovered will provide an indication of the climatic conditions in the area at the time the sediments were deposited. The age of the sediments will be determined with radiocarbon or other dating methods....

chercheur principal: Miller, Raoul
Année(s) de permis: 1990
Résumé: Mr. Miller and Mark Abbott will take water samples and cores from the sediment at the bottom of several lakes on Laird and Becher Peninsulas, Baffin Island. The purpose of the sample collection is to find out about past climate of the area and also to see what impacts human activity in the Arctic might have on these lakes....

chercheur principal: Stewart, Thomas G.
Année(s) de permis: 1979
Résumé: To collect samples of marine and non-marine sediments and to record evidence of driftwood presence in the fiord. The purpose of the study is to create a better understanding of the climate of the area since the last ice age....
