Thermokarst erosion in the Blackstone Uplands

 

Pascale parle pergélisol avec Jacques Dufresne, à Radio-Canada. Ils discutent de sa recherche à Old Crow Flats et d’un voyage récent dans la vallée de la rivière Blackstone, au Yukon.

*Contrairement à ce que dit Jacques Dufresne dans l’intro, Pascale n’était pas à Old Crow Flats cet été avec ses étudiants, mais dans la vallée de la Blackstone. Des résultats liés à Old Crow Flats ont été publiés récemment.

 


Pascale talks ‘pergélisol’ in French with Radio-Canada’s Jacques Dufresne. She discusses some of her research in Old Crow Flats and talks of her recent visit to the Blackstone Uplands, Yukon.

*Note that Pascale was not in Old Crow Flats with students this summer (unfortunately!), but in the Blackstone Uplands of central Yukon. Results from previous research in Old Crow Flats were recently published.

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.

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.

A first video!

Krystal and Pascale submitted a FrostByte video to introduce the research that Pascale will be presenting in Potsdam at the International Conference on Permafrost, June 20 to 24 2016.
