Michel Paquette awarded a PFSN grant for his 2015 summer field work!

May 4, 2015 in post

Congratulations to Michel Paquette, who was awarded a Northern Scientific Training Program grant for his 2015 summer season field work on Ward Hunt Island. This summer he will look at preferential flowpaths through patterned ground and their effect on nutrient mobilisation, sources and sinks.

We wish you a good 2015 field work Michel!

A merit scholarship for Manuel Verpaelst!

March 30, 2015 in post

Congratulations to Manuel Verpaelst for obtaining a merit scholarship granted by the Faculté des études supérieures et postdoctorales (FESP) of the University of Montreal in recognition for his excellent academic record.

Manuel is a M.Sc. student and a member of the Geocryolab under the supervision of Daniel Fortier. His research focuses on the impact of mass movement by solifluction on the evolution of downslope permafrost on Ward Hunt Island, Nunavut, Canada. His thesis should be completed by the end of autumn 2015!

Good luck for the final stretch!

Rapid disappearance of perennial ice cover on Canada’s most northern Lake

March 18, 2015 in post

Canada’s most northern lake, Ward Hunt Lake, has lost its perennial ice cover in 2011 and 2012. According to scientific archives and satellite imagery, this is the first recorded occurrence of complete open water conditions on this lake, usually known for maintaining a >3.5 m thick cover even in late summer. Geocryolab member Michel Paquette shows in a newly published article in Geophysical Research Letters that the decay of the ice cover began in 2008 and is the result of a succession of warm summers from 2008 onwards. The implications of phenological changes of lake ice covers are numerous, they greatly affect limnological conditions such as thermal regime and stratification, water chemistry and lake biology.
