Résumé:
This licence has been issued for the scientific research application No. 5617.
Within the Central Mackenzie Valley of the Northwest Territories (NWT), discontinuity and rapid change within the regional permafrost is anticipated to be influencing landscape, hydrology, habitat and ecosystem characteristics along with presenting challenges for the stability of constructed infrastructure. Mapping t...

Résumé:
This licence has been issued for the scientific research application No.5390.
The research team propose investigating icy Arctic scarps as analogues for ice-exposing scarps on Mars. Scarp-side exposures of massive tabular ice, overlain by a polygonized overburden dotted with thermokarstic depressions, occur in the continuous and extremely deep permafrost of the Tuktoyaktuk Coastlands in the Can...

Résumé:
This licence has been issued for the scientific research application No.5340.
Main objective of the project is to re-start and maintain study sites after two growing season without any census and sample collections. The research team will also establish additional study sites for regeneration process and soil condition monitoring (detection of permafrost table depth). The team will try again to...
