  1. 11. Factors Controlling Mercury Concentration in Rivers in the Mackenzie River Basin, Northwestern Canada

    Master-uppsats, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Jack Hewitt; [2020]
    Nyckelord :mercury; Mackenzie River Basin; regression; Canada; community-based water monitoring;

    Sammanfattning : Mercury (Hg) in rivers and streams of the Mackenzie River Basin (MRB) presents a risk to fish, aquatic mammals, and humans. This thesis makes use of newly-released water quality data, including total mercury (THg) and dissolved mercury (DHg), gathered through the NWT-Wide Community-based Water Quality Monitoring (CBM) program.

  3. 12. Resilience Through Form : A case study of Metro Boston, Exploring the Relationship of Urban Form & Extreme Heat

    Master-uppsats, KTH/Urbana och regionala studier

    Författare :Gavin Lewis; [2019]
    Nyckelord :urban heat island; extreme heat; urban form; resilience; remote sensing; Metropolitan Boston;

    Sammanfattning : The severity of extreme heat events paired with the urban heat island effect cannot be overstated, as the impacts are substantial and widespread, affecting peak energy demands, transport systems, air and water quality, and most notably causing heat-related illnesses and death. These consequences make evident the importance of reducing heat in urban areas and ensuring that urban populations are safe during extreme heat events. LÄS MER

  4. 13. Effects of Wildfire Burn on Permafrost Landcover and Catchment Hydrology in Manitoba, Canada

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Andreas Andersson; [2019]
    Nyckelord :wildfire; permafrost; catchment hydrology;

    Sammanfattning : Permafrost is a strongly controlling factor on Arctic hydrology due to its effect on ground permeability, and thus surface and ground water flow paths. As wildfires are increasing in occurrence and magnitude in permafrost regions, they may alter the hydrological regime via permafrost thaw and degradation that increases ground permeability. LÄS MER

  5. 14. Spatial planning for windenergy development using GIS : A study of Västernorrland County

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Deepa Manolan Kandy; [2018]
    Nyckelord :Analytical hierarchical processing; fuzzy logic; multicriteria evaluation;

    Sammanfattning : Countries across the globe have started taking measures to reduce the greenhouse gas emissions andto power the future with more sustainable forms of energy. One such initiative towards sustainableenergy generation is through wind energy. The wind energy contribution has shown a drastic increasein Sweden during the last few years. LÄS MER

  7. 15. Soil organic carbon storage, distribution and characteristics in two contrasting permafrostaffected environments : Evaluating the role of alpine and lowland tundra areas in the permafrost carbon feedback

    Magister-uppsats, Stockholms universitet/Institutionen för naturgeografi

    Författare :Didac Pascual; [2018]
    Nyckelord :soil organic carbon; permafrost; tundra; alpine; climate change; feedback; mapping; landcover; landform;

    Sammanfattning : An important portion of the large northern permafrost soil organic carbon (SOC) pool might be released into the atmosphere as greenhouse gases following permafrost thawing and subsequent SOC decomposition under future warming conditions, resulting in a warming amplification known as the permafrost carbon feedback. Improved knowledge about the amount, composition and distribution of the permafrost SOC pool is essential when assessing the potential magnitude and timing of the permafrost carbon feedback. LÄS MER
