Congratulations to Simon Charbonneau, M.Sc. candidate in geography at the University of Montreal, for a Northern Science Training Program (NSTP) scholarship. This scholarship will enable him to complete his second field campaign on Bylot Island, where he is mapping the thermokarst lakes and ponds at the scale of the Qarlikturvik valley using high-resolution satellite images and historical aerial photographs.

NSERC and FRQNT for Karine Rioux!

Congratulations to Karine Rioux for obtaining the Canada Graduate Scholarship awarded by NSERC and the Masters Research Fellowship awarded by the FRQNT. His master’s degree, which will begin in the fall of 2017, under the supervision of Daniel Fortier (UdeM) and Mélissa Lafrenière (Queen’s University), will focus on carbon, nutrient and sediment fluxes from thermo-erosion gullies. These scholarships will help support research and field campaigns at Bylot Island, Nunavut.

Massive ice near Eureka (NU) (M. Paquette)

May 4, 2017 in post by Davesne.G

Ice can be quite abundant in permafrost, but its origin, whether it has been buried or has formed in-situ, is sometimes hard to tell. This picture shows massive ice underlying a thick marine deposit (mostly clay). It was taken in late July in 2013, near the Eureka airport in Nunavut in an active retrogressive thaw slump, a landform created by ice-rich permafrost degradation. The two dark lines crossing the ice mass is reminiscent of structures that can be seen in glaciers, and indicate a possible buried origin for this ice. Analysis of the cryostratigraphy, of the geochemistry and of the crystallography of the ice can help tell the difference. An example of this type of work can be found in this article and in this presentation by lab member Stéphanie Coulombe.
