This licence has been issued for the scientific research application No.5221.
The project is the continuation of year-round eddy covariance measurements of carbon, water and energy fluxes at Scotty Creek, established in 2013.
The key methodology is tower-mounted micrometeorological measurements around the eddy covariance technique using an open-path infra-red gas analyzer and a sonic anemome...

This licence has been issued for the scientific research application No.5181.
The combined temperature and active layer monitoring network extends from Fort Simpson to the Arctic Coast. With monitoring instrumentation already in place through work under previous licenses, the main work of this phase will be data collection. While different parts of the network can be visited at different times ...

This licence has been issued for the scientific research application No.4734.
The objective of this research is to identify impacts of climate change and permafrost thaw on pond methane emissions, and on water chemistry in streams that drain peatland-rich catchments. Impacts on methane emissions will be assessed.
Specific objectives are: 1) to characterize the trends and variability in magn...

2018 Summary:
The goal is to reconstruct long-term environmental change (hundreds to thousands of years) by examining chemical and biological fossil remains preserved in lake sediment cores, in order to better understand how thawing permafrost impacts lake ecosystems.
1) Water chemistry and plankton survey
The research team will collect lake water samples from the study lakes to analyze for water chemistry...

Through this project the following objectives will be addressed: What is the net effect of permafrost thawing-induced biophysical and biogeochemical feedbacks to the climate system? How do these two types of feedback differ between the sporadic and discontinuous permafrost zones? Is the reported
decrease (increase) in net carbon dioxide (methane) exchange based on plot- (<1m2) and ecosystem-scale...

2015 Summary:
The aim of this project is to study the short term and long term effects of different fire intensities on the decomposition of soil organic matter (SOM) in northern boreal forests under changing fire regimes.
The objectives are to: 1) explore the short and long term effects of forest fires with different intensity on above- and belowground biomasses; 2) explore changes in albedo, snow depths an...

Summary:
After 10 years of warming climate conditions, the Canadian Fire Service is leading a field project to re-measure a series of permanent monitoring plots to identify any changes to the forest stand structure, tree growth rates, plant community composition, tree, shrub, herb, and lichen biomass. These changes will be associated with climate trends and environmental factors such as soil type, presence...

20162015 Summary:
The project team intend to study carbon cycling in peatland catchments, in order to determine whether the interactions between wildfire and permafrost thaw causes increased release of greenhouse gases from peatlands and aquatic ecosystems to the atmosphere, and thus cause amplified climate change.
Given the overall objective of the project, the team intend to address five research questions:

2016 Summary:
The goal of this project is to look at how permafrost is changing following forest fire over a range of environmental conditions, with the purpose of improving how change is modeled in the future. The fires of 2014 in the southwestern Northwest Territories (NWT) provide an opportunity to examine how discontinuous permafrost responds to disturbances. This work is being carried out in collaboration ...

This project combines the ongoing monitoring program of the same title (Permafrost monitoring and collection of baseline terrain information in the Mackenzie Valley Corridor, NWT) and the activities previously undertaken by the project title, “Active Layer Monitoring Network in the Mackenzie Valley”.
The objectives of this study are to provide baseline knowledge of permafrost and terrain condit...
