An EnviroNord scholarship for Vilmantas Prėskienis! Congrats!

April 23, 2015 in post by Davesne.G

Congratulations to Vilmantas Prėskienis, PhD student at INRS and member of Geocryolab, who has been awarded the EnviroNorth Interdisciplinary Research Fellowship for the second year in a row. This fellowship helps to support his interdisciplinary research on processes and environmental conditions that affect degradation of organic matter in lakes and ponds in continuous permafrost regions.  The research and doctoral studies, supervised by Isabelle Laurion (INRS) and Daniel Fortier, combine methods and knowledge of geomorphology, biogeochemistry, limnology and microbial ecology. Such combination of disciplines and the relation to northern environments (study is based on fieldworks on Bylot Island, Nunavut) must have led to successful application for the fellowship, and, hopefully, will lead to comprehensive results.

Lyna Lapointe Elmrabti: Recipient of a NSTP scholarship for the upcoming 2015 field season

April 22, 2015 in post by Davesne.G

Lyna Lapointe Elmrabti just obtained a scholarship from the Northern Scientific Training Program (NSTP) which will be used to financially support her field work in Yukon. NSTP is managed by the Canadian Polar Commission.

This summer Lyna will work on carbon stocks from a yedoma located in Beaver Creek area. She will perform new GPR transects and carry out further drilling to complement the data already collected during the sampling campaign 2014.

Congrats Lyna and we wish you a nice fieldwork season !

Yukon – Beaver Creek : Air ducts

By the chimney effect, the air ducts of the experimental section YG7 of Alaska Hwy have proven significantly efficient to preserve the underlying permafrost. One of these is now used to measure the heat flow between the circulating air and the embankment with a high precision. On the picture with me, Benoit Loranger from Pr. Guy Doré’s lab at Université Laval, and behind the camera, Kate Grandmont, from the Geocryolab (thanks for the pic by the way). Thanks to both of them who helped me this day (and many other on different times). The monitoring setup was restarted during Fall’14 for a second winter and records will be collected as soon as possible (Figure 1).

Etienne Godin : Recipient of a NSTP scholarship for the upcoming 2015 field season

April 16, 2015 in @en, post by Davesne.G

Etienne Godin just obtained a scholarship from the Northern Scientific Training Program (NSTP) which will be used to support his field logistics at Bylot Island (NU). NSTP is managed by the Canadian Polar Commission.

This summer Etienne will download the ground temperature data continuously recorded by the automatic logger system deployed in the permafrost nearby a gully. These temperatures are useful to better understand the degrading permafrost evolution and active layer dynamics near a gully.

He will update the gully mapping and localize current erosion zones. He will also sample water in a watershed surrounding a gully to obtain the isotopic signature of the various types of water involved in the permafrost degradation.

We wish you a nice fieldwork season !

Congratulations to Lyna Lapointe Elmrabti and Gautier Davesne who have won a prize for their speeches at the research day of graduate students in geography of the Université de Montréal (Géodiversité).

Lyna, M.Sc. student, supervised by Julie Talbot and co-supervised by Daniel Fortier, presented her research on the apparent climate and ecological change during the late Pleistocene in northern Alaska (Itkillik River Yedoma). Lyna won the prize for best science outreach awarded by the Fonds d’investissement des cycles supérieurs de l’Université de Montréal (FISCUM).

Gautier, M.Sc. student, supervised by Daniel Fortier, presented his work on the spatio-temporal evolution of the marginal alpine permafrost body on the Chic-Chocs Mountains. Gautier won the prize for best oral presentation in physical geography awarded by the Association des Étudiant(e)s des cycles supérieurs en Géographie de l’Université de Montréal (AÉÉCSGUM).
