    Kandidat-uppsats, Stockholms universitet/Institutionen för geologiska vetenskaper

    Författare :Malvina Forbes Halldén; [2019]

    Sammanfattning : The chemical compositions of Cr-spinel extracted from mafic and ultramafic rocks collected on Ellesmere Island in the Arctic Canadian Archipelago were obtained through electron microprobe analyses. The extensively altered rocks are sampled from rock units in the Franklinian MobileBelt, which is representative of a Paleozoic tectonically active oceanic regime of which little is presently known.

  3. 7. Knowledge and Implementation of Climate Change Adaptation in the Infrastructure Sector in Nunavut, Canada

    Master-uppsats, Lunds universitet/Avdelningen för Riskhantering och Samhällssäkerhet

    Författare :Timothy Giger; Kelly Ramsauer; [2019]
    Nyckelord :Nunavut; Arctic; Climate Change Adaptation; Infrastructure; Knowledge; Implementation; Policy; Climate-Sensitive Infrastructure; Social Sciences;

    Sammanfattning : The Arctic is at the forefront of climate change and is considered to be the most at risk, warming at twice the rate of the global annual average. The environment and its inhabitants are and will be subjected to deep transformational shifts, with changes in temperature and climate having potentially worldwide repercussions. LÄS MER

  4. 8. 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. 9. Formation of Sulphides in the Canadian High Arctic Large Igneous Province; Testing the Influence of Sedimentary Rocks

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Erika Hagerfors; [2018]
    Nyckelord :LIPs; HALIP; SIMS; sulphur isotopes; Ni-Cu-PGE ores; environmental deterioration; LIPs; HALIP; SIMS; svavelisotoper; Ni-Cu-PGE malmer; klimatförändring;

    Sammanfattning : Large Igneous Provinces (LIPs) form during short-lived pulses of extensive magmatic activity. LIPs are known for their ability to affect global climate as well as for their Ni-Cu-PGE ore potential. LÄS MER

  7. 10. Securing the Arctic : A comparative study of mainstream media representation of the securitization of the Arctic in Norway and Canada

    Kandidat-uppsats, Högskolan Väst/Avd för juridik, ekonomi, statistik och politik

    Författare :Jonathan Bergvall; Johan Leijon; [2018]
    Nyckelord :Securitization; Arctic; Framing; Mainstream Media; Norway; Canada;

    Sammanfattning : This thesis aims to describe and compare how the securitization of the Arctic is represented in mainstream media of Norway and Canada. As two Arctic nations part of the likeminded group in international relations it is interesting to see how national media frames respective nations’ Arctic interests and strategy. LÄS MER
