Biodiversity changes since the last Ice Age reconstructed from lake sediment cores
chercheur principal: Herzschuh, Ulrike
Année(s) de permis: 2024
Résumé: This licence has been issued for the scientific research application No. 5941. Our aim for this study would be to better understand the climate history and paleoecological since the last glacial maximum at the margin of glaciated regions and to help compare regions between formerly glaciated and unglaciated regions in terms of changes in biodiversity, the movement of the tree line and the effec...

Soil Carbon in the Mackenzie Delta Region
chercheur principal: Phillips, Marcus R
Année(s) de permis: 2015 2014 2013
Résumé: The goal of this research is to understand how landscape processes influence the quantity and quality of soil carbon in the Mackenzie Delta Region. Particular attention will be paid to the depth distribution of soil carbon and how it is affected by differences in vegetation and soil forming processes. Key environmental differences that will be examined include forest vs tundra and delta vs uplands...

Deltaic Lake Sediments as Recorders of Past Carbon Export from Arctic River Drainage Basins
chercheur principal: Vonk, Jorien
Année(s) de permis: 2011 2009 2007
Résumé: The research project goal is to collect surface sediments, bank and levee sediments, particulate sediments and shallow sediment cores from lakes in the Mackenie River Delta, and to evaluate their utility as potential archives of information concerning past permafrost stability by assessing down-core changes in the age and supply of terrestrial carbon. In 2007 and 2009, teams led by Prof. Tim Eglin...

Limnology and Paleoecology of Arctic Lakes
chercheur principal: Smol, John P
Année(s) de permis: 1991 1990
Résumé: The research team will sample approximately 20 lakes located within a 100 km radius of Tuktoyaktuk and within the immediate vicinity of Inuvik. At each lake they will analyze the water for major environmental variables and remove some of the lake mud for future analysis of algal remains....
