  1. 1. Modelling the effects of climate change on ice dynamics at Kangerlussuaq Glacier, Greenland

    Master-uppsats, Stockholms universitet/Institutionen för naturgeografi

    Författare :Jamie Barnett; [2021]
    Nyckelord :Glacier; Greenland; Ice Sheet; Outlet; Discharge; Sea level; Kangerlussuaq; calving; ice mélange; melt; retreat;

    Sammanfattning : A consequence of climate change is rising global sea levels, predicted to bring increased socio-economic and environmental impacts to coastal communities. The Greenland Ice Sheet has become a prominent contributor to rising sea levels, a consequence of the Arctic warming at twice the rate of the global average. LÄS MER

  3. 2. Åsars bildning och modellering av isälvar under äldre och yngre Dryas i Svealand

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Emilie Åström; [2020]
    Nyckelord :esker; channel ice stream; Weichsel; Dryas; flow accumulation; Svealand; åsar; isälvar; Weichsel; Dryas; flödesackumulation; Svealand;

    Sammanfattning : Sveriges geomorfologi har till största del bildats under den senaste glaciationens erosion och depositions processer. Vid denna glaciations avsmältning rann smältvattnet bort från glaciären i isälvarna genom tunnlar under inlandsisen. LÄS MER

  4. 3. Geothermal function integration in ice rinks with CO2 refrigeration system

    Master-uppsats, KTH/Tillämpad termodynamik och kylteknik

    Författare :Juris Pomerancevs; [2019]
    Nyckelord :Ice rinks; CO2 refrigeration system; geothermal energy; heat recovery.; Ishallar; CO2 kylsystem; geoenergi; värmeåtervinning;

    Sammanfattning : Ice rinks are energy intense industrial applications. A typical single sheet ice rink in Sweden uses about 1000 MWh/season. A state-of-the art ice rink systems can use less than 500 MWh/season, indicating the potential for improvements. LÄS MER

  5. 4. Numerical ice sheet modelling using FEniCS

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :André Löfgren; [2019]
    Nyckelord :;

    Sammanfattning : The increase in computational power in the last 20 years has made it feasible to solve the full Stokes equation for ice flow, using finite element methods (FEM). However, the numerical properties of these equations remains largely unknown. This is due to their nonlinear nature, which makes them hard to analyze mathematically. LÄS MER

  7. 5. Ice Sheet Modeling: Accuracy of First-Order Stokes Model with Basal Sliding

    Magister-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Eskil Jonsson; [2018]
    Nyckelord :Ice sheet modelling; First-Order Stokes model; basal sliding; Stokes equations;

    Sammanfattning : Some climate models are still lacking features such as dynamical modelling of ice sheets due to their computational cost which results in poor accuracy and estimates of e.g. sea level rise. LÄS MER
