Peatland biogeochemistry. I seek MSc or PhD graduate students with an interest in addressing questions of the biogeochemistry and ecology of peatlands. In particular, I have an immediate opportunity, to start January 2014:
We seek a dedicated student to conduct laboratory-based measurements of C dynamics (CH4, CO2 and DOC production and DOC biodegradability) in organic materials (e.g. plant litter, permafrost soil, bog and fen peat soils) as part of a FRQNT-supported study of the effect of permafrost thaw on C stocks and fluxes.
This is part of PERPLEX (Influence of changing active-layer thickness on PERmafrost PeatLand trace gas EXchanges and Carbon balance) based on Scotty Creek, a hydrologically-well characterized watershed with discontinuous permafrost near Fort Simpson in the Northwest Territories, Canada. Detailed field measurements of water, CO2, CH4 and DOC fluxes will be made in peatland types comprising raised, forested plateaus with permafrost that drain into permafrost-free, non-forested and partly hydrologically-connected collapse bogs and into a network of permafrost-free and sparsely-forested fens, channeling water toward the outlet of the watershed. The laboratory studies, therefore, are designed to provide explanations of the field patterns.
The M.Sc. program, based at McGill University, can start in either January or September 2014, with initial experiments starting in summer, 2014. Please send enquiries, with CV and academic record, to:
Dr. Tim Moore and

Other interests and opportunities include:
Rates and controls on di-nitrogen fixation in peatlands.
Changes in peatland ecology and biogeochemistry in response to fertilization: we have been running an N and P-K fertilization experiment at the Mer Bleue peatland for 12 years in collaboration with Professor Jill Bubier (Mount Holyoke College). We have measured changes in species coverage and productivity, root dynamics, CO2 cycling and nutrient uptake. Opportunities exist for further detailed process studies within this experiment.
Effect of beaver pond drainage on plant ecology and biogeochemistry at the Mer Bleue peatland. The application of ecological stoichiometry to peatland plants, decompsoition rates and peat accumulation. Detecting graves using the biogeochemistry of soils. We have been examining ways in which soil biogeochemistry can detect the presence of graves, in collaboration with Profs. Margaret Kalacska (Geography) and André Costopoulos (Anthropology). We have shown that methane and nitrous oxide may be useful, as cadaver burial and associated anaerobic conditions lead to elevated concentrations and fluxes of these gases
Current work involves the effect of beaver pond drainage at Mer Bleue on vegetation and CO2 and CH4 fluxes
