On October 15th 2019, while doing field work in the Yukon, Pascale spoke with Radio-Canada’s Phare Ouest host, Marie Villeneuve, about her permafrost research in the Yukon and the recent $5.5 M funding received by PermafrostNet.

Summer 2016 field season in the Blackstone Uplands
In July and August, Emma, Nathan, and Pascale visited the Blackstone Uplands, Yukon, to investigate field conditions at sites that showed signs of increased permafrost degradation between the 1950s and early 2000s. The data collected will be used for Emma’s honor thesis, as she will examine the distribution of thermokarst features in the Blackstone River valley and discuss terrain characteristics at the affected sites.
Photographs of thermokarst features in the Blackstone Uplands and some field work photos are found here, and more pictures of students hard at work in the field are found here. Nathan and Emma’s field work was made possible by funding from the Goodman School of Mines and the Northern Scientific Training Program. Thanks to the Na-Cho Nyak Dun and Tr’ondëk Hwëch’in First Nations for allowing us to conduct field work on their traditional territories.

The eleventh International Conference on Permafrost was held from June 20th to 24th in Potsdam, Germany. The conference was well attended with nearly 800 permafrost scientists and engineers, including many young permafrost researchers.
Eroding bank of a thermokarst lake in Old Crow Flats, Yk.
Pascale presented on the rates of organic carbon input in thermokarst lakes due to the erosion of shorelines in a tundra area of Old Crow Flats.This topic will be addressed in an up-coming paper co-authored with Elyn Humphreys, Zoe Braul, and Chris Burn. Preliminary results indicate that, in the area examined, approximately 0.22 teragrams of organic carbon fall in thermokarst lakes every year due to the erosion of the shorelines, including approximately 0.15 teragrams of organic carbon that was previously stored in permafrost.
