2023 Summary:
This licence has been issued for the scientific research application No. 5781.
The long-term objective of this research programme is to improve the understanding, parameterisation and prediction of water flow and storage processes in peatland-dominated, thawing, discontinuous permafrost.
Over the next 5 years, significant progress toward this long term objective will be made through the foll...

20222021 Summary:
This licence has been issued for the scientific research application No.5448.
This project proposes to monitor wetlands, streams, rivers, and lakes in the Dehcho region, with a focus on understanding current and future trends in aquatic mercury and methylmercury. The region has vast stores of mercury accumulated in organic wetland soils, and there is a risk that disturbances such as permafrost ...

This licence has been issued for the scientific research application No.5219.
Through this project the research group will address the following objectives: 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...

The project of the present application 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 anemometer. These measurements are supported by measurements ...

Summary:
The aim of this project is to combine remote sensing data, field measurements and biogeochemical modeling to improve methane emissions estimates from thawing permafrost peatland landscapes at local, regional and global scales. To accomplish this, the research team will integrate data on water table and vegetation from remote sensing (satellites, unmanned aerial vehicle (UAVs)), with local measurem...

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:

2013 Summary:
The research team aims to study if permafrost thaw in peatlands is linked to rapid losses of organic matter. The field work will focus on extracting a number of cores from different peatland sites that differ in their permafrost status and in fire history. By examining the peat layers in the core the team will be able to reconstruct the history of the site and to link changes in permafrost conditi...

1995 Summary:
Research will be conducted in a peatland complex approximately 12 km west of Fort Simpson (4 km west of the Wrigley Road). The major component of the field work will include the collection of peat cores in both frozen and unfrozen terrain to about 1 m depth. A total of approximately 100 cores will be collected. Core holes will be approximately 15 cm wide, and will be filled to minimize terrain ...
