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.

This licence has been issued for the scientific research application No. 5890.
Through this project my 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...

Summary:
This licence has been issued for the scientific research application No. 5797.
The goals of this multi-year-long project are to assess greenhouse gas (methane and carbon dioxide) release from warming permafrost and tundra lakes in the ISR and to study associated carbon dynamics and microbiological processes, including the release of mercury to the environment.
The first year of field activit...

This licence has been issued for the scientific research application No. 5775.
This activity describes and predicts the occurrence of discontinuous permafrost in the northern Great Slave Lake region to assist in planning, development and maintenance of community and industry infrastructure. Changes in climate are affecting permafrost distribution, temperatures and geotechnical conditions. Diffe...

Summary:
This licence has been issued for the scientific research application No. 5646.
This project proposes to evaluate responses of aquatic ecosystems to permafrost thaw, lake drying, and wildfire, as well as their cumulative impacts. The researchers will characterize lake chemistry and biological diversity (microbes and invertebrates) in water (current environmental change) and in sediments (histori...

Summary:
This licence has been issued for the scientific research application No. 5655.
This project aims to investigate the three-dimensional subsurface structures in the vicinity of active retrogressive thaw slumps and their relationship to spatio-temporal slump-development. The number and activity of retrogressive thaw slumps have increased during the last decades due to climatic, hydrologic and ther...

Summary:
This licence has been issued for the scientific research application No.5564.
The main goal of the project is to understand how gradients in tundra vegetation and permafrost thaw affect soil carbon and mercury cycling. This will allow the research team to assess how permafrost thaw and changes in vegetation in a warmer climate could alter future carbon dioxide fluxes and impact mercury cycling ...

Summary:
This licence has been issued for the scientific research application No. 5656.
The objective is to conduct airborne surveys at 3300ft (1000m) altitude to collect high-resolution aerial images and LiDAR elevation data that can be used to describe and quantify rates of permafrost thaw, coastal erosion, thaw slumping, lake change, and vegetation change. Daily survey flights (depending on cloud-fre...
