Summary:
This licence has been issued for the scientific research application No. 5892.
Objective summary: To assess the effect of wildfires on changes in water quality in the Dehcho and South Slave region, which are affected by runoff from peatlands (containing e.g., organics, nutrients, and mercury/methylmercury), which are already experiencing increased permafrost thaw due to climate change.
Synop...

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...

Summary:
This licence has been issued for the scientific research application No.5468.
The goal of this project is to understand and predict how lakes in discontinuous permafrost peatlands are changing in response to climate warming and loss of permafrost.
The field activities for 2023 will focus on three regions/objectives:
Inferring long-term environmental change in the Five Fish Lakes (Lue Túé ...

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:
This licence has been issued for the scientific research application No.4705.
The Mackenzie River Basin (MRB) is one of the largest cold-water, intact boreal ecosystems in the world and has unique Earth-system’s processes associated with sea ice formation, global circulation of deep ocean currents, carbon storage, and biogeochemical cycling. This unique global resource is also critical for supp...

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...

201720162015 Summary:
The goal of this project is to identify and collect remote sensing and field data to support the science necessary to investigate the impacts and consequences of the 2014-15 wildfires in Northwest Territories, Canada and to better understand the vulnerability of the Carbon-rich boreal peatlands to burning.
Field crews will navigate to pre-selected sample locations and collect at each location: ...
