Understanding the integrated eco-hydrological behaviour of ecosystems in the context of thawing permafrost is a major challenge. To meet this, the research team will measure the present surface and near-surface water supplies and their inter-annual variability assuming a condition of no permafrost thaw. The team will also develop new knowledge on the eco-hydrology of the major ecosystems (i.e. bog...

The broad goal of this research is to increase understanding of tundra carbon balance of terrestrial and aquatic ecosystems and predict into the future the impacts of climate warming on these systems.
Since the research team are interested in all aspects of the tundra carbon balance a variety of methods are employed. These can be broken down into 4 basic categories:
1. Tundra-atmosphere flux...
Principal Investigator:Sonnentag, Oliver Licenced Year(s):
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...

The goal of this research over the next five years is to substantially advance the understanding of how Canadian arctic tundra ecosystems function, and therefore how they are likely to be affected by perturbations such as climate change, resource development and extraction, and atmospheric pollution. Specifically, the research team will focus on the impacts on vegetation due to warmer summer tempe...

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. uplan...
Principal Investigator:Lantz, Trevor C. Licenced Year(s):201620152014
This project has three main objectives:
Objective 1: To use satellite imagery (Landsat, QuickBird, InSAR, etc.) to document the rate and extent of landscape change (slumps, subsidence, vegetation change, etc.) in the northern Mackenzie Basin.
To quantify landscape disturbances and vegetation regeneration patterns since 1985 Landsat satellite images will be obtained that will provide reflec...
Principal Investigator:Grieve, Sheryl Licenced Year(s):2010
This project is part of a larger IPY study, CiCAT, which is looking at the effect of climate change on arctic tundra ecosystems. For their project, the researchers will be collecting North Slave Métis Community’s traditional knowledge on vegetation and terrain changes in the North Slave region. In addition, they will be collecting and commenting on the scientific methodology for the larger CiCAT p...

Since the 1970s, the oil and gas industry has drilled at least nineteen exploratory wells in the Kendall Island Bird Sanctuary. Observations at associated drilling mud-sumps have been made; however, there remains a paucity of field data describing site conditions. It is also appreciated that construction of the proposed Mackenzie Valley pipeline will stimulate the development of Niglintgak and Tag...
Principal Investigator:Chen, Wenjun Licenced Year(s):2005
The objectives of the research are to become familiar with the vegetation and landforms of northern Canada, and to collect vegetation and biophysical data for ground truth of remote sensing and carbon modeling activities. The Dempster Highway provides a...
Principal Investigator:Callow, Lin Licenced Year(s):
The objective of these trials is to evaluate the performance of Low Ground Pressure Vehicles (LGPV) on frozen tundra without surface preparation. The effects of LGPV passage on soil, permafrost, and vegetation will be monitored and the details of each tr...
