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

May 24, 2017 in @en by Davesne.G

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!

May 23, 2017 in @en, post by Davesne.G

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.

 

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.

Congrats to Karine Rioux for its excellent talk at Géoforum!

April 24, 2017 in @en, Article by Davesne.G

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 experimental section of the Alaska Highway (Yukon). Karine skillfully demonstrated thermal dynamics of the air and the firsts centimeters of permafrost under the snowsheds, compared with a test section. Her good work and communicating skills won her the prize of the best honors presentation in physical geography! Congratulations Karine!

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

April 19, 2017 in @en, post by Davesne.G

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 heavy equipment and food that are shipped by cargo flight to PCSP base in Resolute Bay. A careful preparation is crucial in order to precisely estimate the needs for the field season.

Gautier Davesne and Audrey Veillette shipped their equipment and food this Monday, which means that the field season will start soon…

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

December 2, 2016 in @en, post by Davesne.G

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 combined influence of aeolian sand clogging and climate warming. The soil properties and scanning electron microscope / energy dispersive X-ray (SEM / EDX) were conducted. And a two-dimensional unsteady finite-element model was used to simulate the impacts of climate warming and aeolian sand clogging of CRIE on its cooling performance.

Yukon – evolution of a drainage ditch near the road (Michel Sliger)

November 28, 2016 in @en, focus-en by Sliger.M

A drainage ditch was 75 cm wide right after its excavation in October 2010. Two years later, it’s almost stabilized at 4 m wide. Few rivulets continue to lead some sediments movements building micro fluvial deltas. Pioneer vegetation colonized the bottom where the water doesn’t stand still or the sediment doesn’t accumulate (Figure 1).

What is the impact of subsurface water flow on the thermal regime of the ground? (Daniel Fortier)

November 15, 2016 in @en, post by Davesne.G

In response to climate changes, permafrost thaw and active layer deepening shall favor the increase of subsurface water flow. Geocryolab designed experimental cells to evaluate the thermal ipact of groundwater on the ground thermal regime. Why? Because very few information is currently available about this topic and because laboratory study allows for a simplification of the parameters influencing the temperature and a better control of these parameters.
