201520142013 Résumé:
The objectives of this research project are to: 1) determine if the net effect of permafrost thawing-induced biophysical and biogeochemical feedbacks to the climate system; 2) determine how these two types of feedback differ between the discontinuous and continuous permafrost zones; 3) determine if the reported decrease (increase) in net CO2 (CH4) exchange based on plot- (<1m2) and ecosystem-scale...

Résumé:
Uniform permafrost and ground surface temperature measurements are one of the more important databases for long-term climatic study as well as remote sensing ground truthing data. Consistency in sensor depth, casing and drilling methods helps in comparison of the spatial and temporal distribution of the permafrost and seasonal conditions. The proposed partnership with the schools aids continuous m...

The objective of this research is to understand how climate change is affecting permafrost in the western Arctic, particularly in the outer Mackenzie delta. The research team also intends to investigate the ice content of the ground and how this may affect terrain stability. The research team wishes to study changes in ground temperature at various locations in the western Arctic, ranging from Her...

20092007 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...
