Seeking a Post Doctoral Fellow with research interests and experience in permafrost watershed organic carbon dynamics and geochemistry. The objective of the research is to gain a better understanding of how different hydrogeomorphic conditions (e.g., polar desert vs. wetland) and hydrological inputs (e.g., snow vs. rain, vs. subsurface flow) affect the size distribution, abundance and molecular composition of DOM in aquatic systems in the High Arctic.
The research will involve the use of ultrafiltration techniques, to size fractionate DOM from surface waters collected from permafrost watersheds. The work will require laboratory analyses and laboratory experiments to be conducted in the FaBRECC lab at Queen’s University for approximately the first half of the appointment followed by data analyses and interpretation. Analytical skills that are required include the operation of high temperature combustion TOC analyser (Shimadzu TOC-L) and an Aqualog spectrofluometer.
The successful candidate should have strong quantitative skills including experience with MATLAB or similar software for statistical analyses and data processing. The PDF will also have the opportunity to collaborate with Dr. Myrna Simpson at the UofT Scarborough, to use NMR analyses to characterize the molecular structure of DOM by size fraction.
It is expected that this work would result in at least one publication submitted within the term of the appointment. The position will also afford the successful applicant the opportunity to participate in other research endeavors and to assist in supervision and training of students in laboratory according to their interests and qualifications.
