Tim N. Papakyriakou
Professor

(Biography) My academic background includes: a B.Sc. from McMaster University (1985); a M.Sc. from Queen?s University (1990); and a Ph.D. from the University of Waterloo (1999). Thesis topics range from an examination into the effect of atmospheric aerosol loading on surface insolation at Canadian urban centers (Honours BSc), an assessment of a forest water budget model (M.Sc.) and a sea ice heat budget and physical property study within the Canadian Arctic Archipelago (Ph.D.). I started my career as a faculty member at the University of Manitoba with the Department of Geography (now the Department of Environment and Geography) in 1999. I teach courses in areas of microclimatology and hydrology. I conduct research in the area of microclimatology ? examining the relationships between the near surface atmosphere, and the biological and physical make-up of the underlying environment. I do this by monitoring the linkages among the systems' heat budget (an accounting of radiation and heat flows between the atmosphere and surface and changing heat stores within the system), properties of the system and those ecosystem functions (physical and physiological) that affect, and that are affected by climate. The processes that link the atmosphere and surface are strong functions of both surface characteristics and climate and therefore vary both spatially and temporally. I maintain research projects in Prairie Manitoba and Arctic Canada. My northern work has both a marine and terrestrial component. In the Arctic marine environment, I combine field measurements of the atmospheric CO2 concentration and near-surface CO2 flux with measurements of sea ice and surface sea water biogeochemistry and biology, distributed in time and space, to better understand the nature and drivers of the air-sea (and sea ice) CO2 flux so that we may comment on the role of the Arctic Ocean, and its associated shelf environments, on the global carbon cycle. I rely largely on measurements of surface fluxes of heat, water and CO2 from ship and sea ice based towers in support of the research. Within the coastal environment, I am interested in land-sea coupling and its effect on microclimate and associated ecosystem properties. As in the marine case, I rely heavily on tower-based measurements of surface fluxes to provide insight into the behaviour of coastal ?bioclimate? to maritime forcing.
