Arctic Expedition
chercheur principal: Cherrak, Marion
Année(s) de permis: 2023
Résumé: This licence has been issued for the scientific research application No. 5623. This project will be supervised by UNIGE, Geneva University and conducted onboard by Noémie Planat, a PhD student at McGill University. This study will continuously monitor environmental data (greenhouse gasses (carbon dioxide and methane) and standard oceanographic parameters in surface water/water column, and the p...

Effects of fire on peatland permafrost stability and carbon cycling
chercheur principal: Olefeldt, David
Année(s) de permis: 2017 2016 2015
Résumé: The project team intend to study carbon cycling in peatland catchments, in order to determine whether the interactions between wildfire and permafrost thaw causes increased release of greenhouse gases from peatlands and aquatic ecosystems to the atmosphere, and thus cause amplified climate change. Given the overall objective of the project, the team intend to address five research questions: ...

The ecology and paleoecology of benthic macroinvertebrates in the Mackenzie Delta region
chercheur principal: Quinlan, Roberto
Année(s) de permis: 2017 2016 2015 2014 2013
Résumé: This study will examine the effects of permafrost and flooding on the ecological structure and carbon exchange of contrasting lakes in the Mackenzie River Delta. Permafrost thaw in lake catchments may cause increased transport of organic carbon and dissolved nutrients to lakes with effects on the hydrology and water chemistry of lake environments. Patterned ground marked by ice-wedge polygons is f...
