Impact of permafrost thaw and wildfire on carbon storage in peatlands
chercheur principal: Turetsky, Merritt R.
Année(s) de permis: 2014 2013
Résumé: The research team aims to study if permafrost thaw in peatlands is linked to rapid losses of organic matter. The field work will focus on extracting a number of cores from different peatland sites that differ in their permafrost status and in fire history. By examining the peat layers in the core the team will be able to reconstruct the history of the site and to link changes in permafrost conditi...

Effects of wildfire on biomass combustion in boreal peatlands and forests
chercheur principal: Turetsky, Merritt R.
Année(s) de permis: 2011
Résumé: The objective is to quantify the amount of fuel combustion and carbon losses during wildfires in boreal conifer forests and peatlands. These data will allow us to quantify climatic and weather controls on the severity of biomass burning. Boreal forests and peatlands store a large amount of carbon in vegetation and soils. Climate change is predicted to increase summer drought, which could mak...

Composition of natural dissolved organic carbon in streams along latitudinal transect
chercheur principal: Turetsky, Merritt R.
Année(s) de permis: 2011
Résumé: The goal of this research project is to measure the concentration and composition of natural dissolved organic carbon in rivers along a latitudinal transect from central Alberta to southern NWT. Data on water quality will be combined with spatial data that describes the drainage basins of the sampled rivers, e.g. ecosystem composition, size, slope, recent fire impact and permafrost conditions. The...
