​Hello, Dear Colleagues,


Two Ph.D. studentships in C Dynamics in Boreal Drained Peatlands are available 
at my lab at Memorial University of Newfoundland (Canada). Please see the 
details below or the attached for the positions.


Best regards,

Two Ph.D. studentship available at Memorial University of Newfoundland 
(Canada):  Greenhouse gas emissions in boreal peatlands affected by 
agricultural draiange

Two Ph.D. studentships are available at the Terrestrial Biogeochemistry and 
Ecohydrology Research Group (TBERG) of Memorial University of Newfoundland 
(Canada). The studentships are part of the project “Examining the impacts of 
agricultural drainage on carbon cycling of northern peatlands”, funded by 
NSERC. The studentships are available fully funded for four years, starting 
immediately or as early as possible.

The big research question that this project attempts to address is “how is the 
carbon cycling (carbon dioxide and methane) in northern peatlands altered by 
agricultural drainage and how can we incorporate the field observation-based 
knowledge into peatland ecosystem carbon models?”

Ph.D. 1: Examining the impacts of agricultural drainage on greenhouse gas 
emissions (carbon dioxide, methane and nitrous oxide) in boreal peatlands.

Your research work will include, but not limited to, (1) quantify greenhouse 
gas emissions from boreal peatlands affected by agricultural drainage; (2) 
measure the temporal and spatial variability of greenhouse gas emissions; (3) 
determine the biotic and abiotic regulatory factors and their relationships 
with greenhouse gas fluxes.

The measurements of greenhouse gas fluxes are based on static chamber methods 
and gas chromatography, and eddy-covariance tower measurement. All these 
measurements have been continuously carried out starting from the summer of 
2013.  We have installed a pair of eddy covariance (EC) tower, equipped with 
LI-7200 and LI-7700, on our research sites, one on the natural peatland, and 
the other one on abandoned peatland pasture with active drainage, and they have 
been operational since September 2013.

You should have excellent oral and written communication skills in English, and 
the appropriate academic background, for example, in soil science, ecology, 
earth system science, physical geography, hydrology, biogeochemistry, forestry 
ecology, and micrometerology, and other suitable subjects, to analyze the large 
EC data. You are required to regularly visit the sites year-round to collect 
gas samples from static chambers, and maintain the proper function of EC tower, 
analyze the sample in the lab, write high-quality manuscripts for peer-reviewed 
publication in the high impact journals, presentation in international/national 
conferences, and other requirement for a Ph.D. degree.




Ph.D. 2: Modeling the impacts of agricultural drainage on greenhouse gas 
emissions (carbon dioxide and methane) in boreal peatlands.

The research question directing this project is “how can the changes in 
biogeochemical properties in boreal peatlands affected by agricultural drainage 
be parameterized in the McGill Wetland Model (MWM) or DeNitrification and 
DeComposition Model (DNDC)”?  Either MWM or DNDC needs to be adapted to 
incorporate the changes in hydrology and vegetation composition in the 
agriculturally drained peatlands. The newly developed/adapted model will be 
evaluated against the continuous eddy-covariance tower measurements (carbon 
dioxide and methane). If feasible, you are also expected to examine how these 
agriculturally drained peatlands would be affected in the future projected 
climate change in terms of carbon dioxide and methane fluxes. We have 
continuous half-hour C flux data (carbon dioxide and methane) from a natural 
peatland and an agriculturally drained peatland since September 2013.

You are required to have: excellent oral and written communication skills in 
English; appropriate academic background, for example, in soil science, 
ecology, earth system science, physical geography, hydrology, biogeochemistry, 
forestry ecology, and micrometerology, and other suitable subjects; strong 
numerical analytical skills; experience with process-based ecosystem modeling; 
A good understanding of peatland/wetland biogeochemistry, wetland/peatland 
hydrology and biophysical drivers of peatland/wetland processes; experience in 
computer programming (for example, Fortran, or C, C++) preferred. You are also 
required to write high-quality manuscript for peer-reviewed publication in the 
high impact journals, presentation in international/national conferences, and 
other requirement for a Ph.D. degree.



If you are interested in either of the two positions, please send a letter of 
motivation/research statement, evidence of English Proficiency (if required for 
international students), up-to-date curriculum vitae, unofficial transcripts, 
and a copy of any publication (if available) to Dr. Jianghua Wu at 
jwu@grenfell.mun.ca<mailto:jwu@grenfell.mun.ca> with subject “Ph.D. 
studentship”. Reviewing is started immediately after your files are received.
