Investigating the processes controlling evapotranspiration from disturbed northern ecosystems.

Thesis Summary:

M.Sc. Thesis "Micrometeorological Fluxes and Controls on ET for a Jack Pine Stand Growing on Reclamation Soil Cover, Fort McMurray, AB." -- Carleton University, 2008.

Due to the constructed nature of oil sand reclamation sites, it is uncertain whether or not biophysical processes at these sites mirror those of natural boreal ecosystems. Therefore, to asses this, turbulent fluxes of energy and mass were measured using the eddy covariance technique over a 15-year-old planted jack pine ( Pinus banksiana ) stand on reclamation soil cover in northern Alberta during the 2007 growing season.

The first half of the field season was predominantly dry, with relatively constant levels of daily evapotranspiration (ET) being supplied by soil moisture stored from spring snowmelt. Drought-like conditions developed for a short period when soil moisture was limiting on ET, with a midday Bowen ratio consistently equal to or greater than 2. In the second half of the study period, with increased precipitation and available soil moisture, midday energy partitioning of turbulent fluxes was fairly equal. Daily ET ranged from 0.2 - 3.6 mm d-1, with mean values over the study period of 1.75 +/- 0.75 mm d-1.

In addition to examining the magnitude and temporal variability of the mass and energy fluxes at the study site, the biotic and abiotic factors which control ET were assessed . Soil moisture availability had a significant effect on the seasonal variability of ET. Despite soil moisture limitations, bulk surface resistance was found to exert only a moderate biological control on the latent heat flux with mean decoupling coefficient values of 0.15 - 0.30, where the effects of the atmospheric vapour pressure deficit, photosynthetic photon flux, and available water were examined using a non-linear multiplicative model.

Linking climate or land-use changes to the ecohydrological response of peatlands and boreal forests.
