Landscape scale flooding in the Great Slave Lake Plain
chercheur principal: Armstrong, Terry
Année(s) de permis: 2014 2013 2012 2011 2010
Résumé: The objectives are to draw together multiple sources of information so that we may (1) examine change in lake area in this ecoregion, (2) assess amount of meadow habitat lost to rising water levels in core bison range, (3) investigate whether recent changes are part of a longer-term cycle and evaluate the causes of this change, (4) determine a way to document and integrate local and traditional kn...


Changing fire regimes in northern coniferous forests
chercheur principal: Wallenius, Tuomo H
Année(s) de permis: 2009
Résumé: This licence is being issued for the scientific research application No.1103. The research objective is to study the occurrence of forest fires in Northern Canada during the past 200 years. They are especially interested in large scale averages and changes in the estimated fire return intervals/annually burned proportions of the landscape. Specific research questions are: 1. How often for...


Using Tree Rings and Lake Sediment to Reconstruct Streamflow and Climate in the Northwest Territories
chercheur principal: Lamoureux, Scott F
Année(s) de permis: 2002
Résumé: The objective of the research is to supplement and extend instrumental climatological and hydrological records in the NWT using dendrochronology (tree-ring) and varved lake sediment analysis. Transportation to the site will be by charter aircraft from Fo...


Ecophysiological Reconstruction of High Latitude Fossils
chercheur principal: Jagels, Richard
Année(s) de permis: 2000
Résumé: The NWT component of this study is to examine how the anatomical features of wood from the genus Larix, vary with changes in latitude. This will be compared to work done on Axel Heiberg Island, Nunavut where a fossil forest of mummified wood approximately 45 million years old was found. Certain features of wood can provide clues to assess winter temperatures but these features vary with latitude....


Extensive Dendrochronological Reconstruction of Temperature in the Northern Hemisphere: North American Boreal Zone
chercheur principal: Jacoby, Gordon C.
Année(s) de permis: 1994 1989
Résumé: The object of this research is to reconstruct past climate in order to understand how the climate system works, and what past natural variations may be expected based upon this information. This project is to sample old-aged trees and to assemble enough coverage to reconstruct regional and Hemispheric temperatures for the most recent centuries....
