This report describes the inventory system developed to provide a comprehensive data base for emission of materials to the atmosphere which are judged to be of environmental concern in the AOSERP study area. A detailed evaluation of man-related activities and natural processes within the area was...

Boxed-in: Comparing Algorithms for Box-flight Mass-Balance Greenhouse Gas Flux Measurements from Mineable and In Situ Oil Sands Developments
DownloadSpring 2022
To combat global warming, Canada has committed to reducing greenhouse gases (GHGs) 40-45% below 2005 emission levels by 2025. Monitoring emissions and deriving accurate inventories are essential to reaching these goals. GHGs can be measured at a small scale, often using ground measurements which...

Changes in peatland plant community composition and stand structure due to road induced flooding and desiccation
DownloadFall 2017
Roads built through peatlands with horizontal water flow can to act as dams that affect local hydrology and thus vegetation composition and structure. On the ‘upstream’ side of roads, soils can become waterlogged causing either increased tree mortality, or stunted tree growth; conversely, the...

Consequences of peatland disturbance for dissolved organic matter and nutrient transport and fate in northern catchments
DownloadFall 2023
Northern peatlands contain ~415 Pg of carbon (C) in soil organic matter and are significant sources of dissolved organic matter (DOM) in inland waters. DOM includes a range of molecules that are C-rich and may also contain nitrogen (N) and phosphorus (P). The escalating disturbance of peatlands...

Rankin, Robert , Degeling, Alex W., Watt, Clare E.
We introduce a new methodology that allows the construction of wave frequency distributions due to growing incoherent whistler-mode waves in the magnetosphere. The technique combines the equations of geometric optics (i.e., raytracing) with the equation of transfer of radiation in an anisotropic...

Spring 2024
This work aims to conduct a techno-economic feasibility analysis of adopting a hybrid approach to hydrogen generation. This includes grey hydrogen sourced from natural gas using Steam Methane Reforming (SMR) and green hydrogen from renewable energy. The key focus is on assessing the environmental...

Development and Applications of an Emissions Micro-Simulation Tool for Transportation Infrastructure Design
DownloadFall 2014
Transportation emissions constitute a significant portion of overall emissions inventories, and contribute to air quality health concerns. Reductions in transportation emissions can be achieved through efficient design of infrastructure, effective policy and regulation, and informed planning...

Examination of Wet Meadow Creation as a Restoration Option for Extracted Peatland Sites in Alberta
DownloadSpring 2014
Question: Can a wet meadow plant community be established on abandoned peatlands through broadcast plant diaspore spreading in western Canada? Does fertilization impact the development and establishment of the wet meadow? Location: Evansburg, Alberta, Canada Methods: Wet meadow vascular and...

Factors influencing size inequality in peatland black spruce and tamarack: Evidence from post-drainage release growth
Download1999
1 We used tree ring analysis to determine stem radius and thus examine size variation over time in two even-aged (approximately 40-year-old) mixed populations of black spruce and tamarack established on peatlands in a boreal forest. We also followed the response of one of these populations to...

Formation and maintenance of permanent perched wetlands in the Boreal Plain of Western Canada
DownloadSpring 2017
The Boreal Plains Ecozone is characterized by a moisture deficit climate, as regional precipitation is less than potential evapotranspiration. Perched peatlands situated 20 m above regional groundwater have been identified as common features across the landscape in the Utikuma Region Study Area...
