Simon Charbonneau: Recipient of a NSTP scholarship for the upcoming 2017 field season

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

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

Audrey Veillette: Recipient of a NSTP scholarship for the upcoming 2017 field season

Congratulations to Audrey Veillette who was awarded a Northern Scientific Training Program grant for supporting her work on Ward Hunt Island this summer. She will be there from May 31st to July 12, working on the field with her colleague Gautier Davesne.

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

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

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

Congrats to Karine Rioux for its excellent talk at Géoforum!

Congrats to Karine Rioux for its excellent talk at Géoforum!

On the 21st of April, Karine Rioux presented the main part of her honors bachelor project. Her presentation was part of the GeoForum 2017 of the Geography department (University of Montreal). Her project consists in evaluating the efficiency of a mitigation technique; the use of snowsheds to increase the thermal stability of permafrost along an

Shipping of field equipment to Resolute Bay (NU)! (G. Davesne et A. Veillette)

Shipping of field equipment to Resolute Bay (NU)! (G. Davesne et A. Veillette)

The preparation of field summer in the Arctic begins in the fall with the logistic support (ex. Polar continental shelf program) and permits (ex. Parks Canada) requests. Once the supports and permits are accepted, generally in February and March, it’s time to plan the field season. The most important step is the preparation of the

Isotopic analysis of water (M. Paquette)

Isotopic analysis of water (M. Paquette)

When all you need is a few millilitres. These 2 ml bottles are more than enough for measuring isotopic composition of water. This technique has many application, but in this case we are trying to figure out what percentage of the water flowing through the water tracks of Ward Hunt Island originate from snowmelt and

Patterned grounds on Ward Hunt Island (M. Paquette)

Patterned grounds on Ward Hunt Island (M. Paquette)

Patterned Grounds! Among the most interesting features of periglacial areas are these self-organised soil mosaics, which can take a wide range of shapes and size and are created by freeze-thaw cycles. The type of soil and the slope angle is very important in deciding the shape and the size of the patterns. This picture was

Permafrost cores analysis in the lab (Michel Paquette)

Permafrost cores analysis in the lab (Michel Paquette)

While summers are for field work and data and sample collection, winters in the Geocryolab are spent analyzing those in the lab and in the offices. A widespread method used by lab members is the cryostratigraphic analysis, which describes and quantifies the pattern of soil and ice structures in permafrost. It informs on the formation

Physical properties and microstructure of aeolian sand (By Lin Chen)

Physical properties and microstructure of aeolian sand (By Lin Chen)

Climate warming and human activities have led to significant grassland degradation and desertification on the Qinghai-Tibet Plateau (QTP). The performance of Qinghai-Tibet Railway (QTR) have been affected by aeolian sand transportation and deposition. The physical properties of aeolian sand are of importance to evaluate the long-term thermal performance of crushed-rock interlayer embankment (CRIE) under the
