• Characterizing the transport of hydrocarbon contaminants in peat soils and peatlands 

  Gharedaghloo, Behrad (University of Waterloo, 2018-09-04)

  Widespread transportation corridors crossing Canadian peatlands make these landscapes vulnerable to hydrocarbon spills. After a spill happens, free hydrocarbon spreads in the peat layer forming a free-phase plume. Water ...

• Political feasibility of 1.5°C societal transformations: the role of social justice 

  Patterson, James J; Thaler, Thomas; Hoffmann, Matthew; Hughes, Sara; Oels, Angela; Chu, Eric; Mert, Aysem; Huitema, Dave; Burch, Sarah; Jordan, Andy (Elsevier, 2018-04-01)

  Constraining global climate change to 1.5°C is commonly understood to require urgent and deep societal transformations. Yet such transformations are not always viewed as politically feasible; finding ways to enhance the ...

• “Ne nnipadua mmpe” (the body hates it): Exploring the lived experience of food allergy in Sub-Saharan Africa 

  Atiim, George A.; Elliott, Susan J.; Clarke, Ann E. (Elsevier, 2018-05-01)

  Allergic diseases have closely followed the rise of non-communicable diseases (NCDs) especially in western societies. As prevalence of NCD is increasing in sub-Saharan Africa (SSA), researchers are hinting that the same ...

• Estimation of Phytoplankton Chlorophyll-a Concentration in the Western Basin of Lake Erie Using Sentinel-2 and Sentinel-3 Data 

  Mollaee, Somayeh (University of Waterloo, 2018-07-04)

  Worldwide phenomena called algae bloom has been recently a serious matter for inland water bodies. Temporal and spatial variability of the bloom makes it di cult to use in-situ monitoring of the lakes. This study aimed to ...

• Hydrology and Nutrient Biogeochemistry of Shallow Pond-Peatland Complexes, Hudson Bay Lowlands 

  Morison, Matthew (University of Waterloo, 2018-06-25)

  Across the circumpolar north, the degradation of permafrost in tundra and peatland landscapes has resulted in significant changes to land cover, including an increase in the extent of thermokarst landforms. Climatically-driven ...

• Public participation in the Geoweb era: Geosocial media use in local government 

  Zhang, Shanqi (University of Waterloo, 2018-06-21)

  Advances in spatially enabled information and communication technologies (ICTs) have provided governments with the potential to enhance public participation and to collaborate with citizens. This dissertation critically ...

• Abiotic controls of fine sediment on the form and mobility of phosphorus in a gravel-bed river during low flow 

  Watt, Caitlin (University of Waterloo, 2018-06-18)

  Landscape scale disturbance in forested source water regions can accelerate the transfer of fine sediment and associated phosphorus (P) to receiving streams and degrade water quality in downstream environments for human ...

• Climatological trends and predictions in snowfall over the Canadian snowbelts of the Laurentian Great Lakes Basin 

  Baijnath-Rodino, Janine (University of Waterloo, 2018-06-11)

  The leeward shores of the Laurentian Great Lakes are highly susceptible to lake-induced snowfall that is either driven by extratropical cyclones or lake effect processes. During the late autumn and winter season, cold air ...

• Toward Automated Ice-Water Classification on Large Northern Lakes Using RADARSAT-2 Synthetic Aperture Radar Imagery

• Sulfur biogeochemistry in a constructed fen peatland in the Athabasca Oil Sands Region, Alberta, Canada 

  Osman, Fares (University of Waterloo, 2018-05-14)

  In peatlands, increased sulfate (SO42-) availability can stimulate dissimilatory SO42- reduction (DSR), allowing it to become a prominent anaerobic carbon (C) mineralization process. In turn, methane emissions may be ...

• Impacts of freeze-thaw processes on phosphorus release from a variety of cover crop species in a temperate climate 

  Cober, James (University of Waterloo, 2018-04-30)
