  1. 1. 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

  2. 2. Mapping of Water under a Part of the Greenland Ice Sheet Using Ice-Penetrating Radar

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Anna Svensson; [2015]
    Nyckelord :Greenland; hydrology; radar; attenuation; reflectivity; CMP; Grönland; hydrology; radar; dämpning; reflektivitet; CMP;

    Sammanfattning : The contribution to the global sea level change from the large ice sheet of Greenland and Antarctica if both ice sheet where to melt completely, is estimated to be approximately 70 meters. How much the actual contribution would be, is due to complex ice dynamics still unclear. LÄS MER

  3. 3. Modelling albedo in the ablation zone of the Greenland ice sheet

    Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

    Författare :Marie Rasmussen; [2014]
    Nyckelord :albedo; Greenland; Physics and Astronomy;

    Sammanfattning : Abstract An ice sheet always experience more or less melting during the summer. How much melting that occurs, is mostly determined by the albedo. Albedo is defined as the amount of the incoming shortwave radiation that gets reflected by a surface. When the sunlight starts melting the ice and snow in the summer, the albedo gets lower. LÄS MER

  4. 4. The Late Glacial History of the Magellan Strait in southern Patagonia, Chile : Testing the Applicability of KF-IRSL Dating

    Master-uppsats, Stockholms universitet/Institutionen för naturgeografi

    Författare :Robin Blomdin; [2012]
    Nyckelord :;

    Sammanfattning : The timing of the ice margin retreat of the Late Glacial Patagonian ice sheet (PIS) in southern Patagonia has been the object of discussion for many years. In order to resolve questions about the complex response of the PIS to past climate change; geological interpretation and modelling data needs evaluation against absolute chronology. LÄS MER


    Master-uppsats, KTH/Tillämpad termodynamik och kylteknik

    Författare :Mazyar Karampour; [2011]
    Nyckelord :Ice Rink; Refrigeration; Heat Load; Power Consumption; Energy Efficiency; Modelling; Measurement;

    Sammanfattning : Ice rinks are among the most energy intensive public buildings in developed and developing countries. According to a research on Swedish ice rinks; a typical ice rink consumes approximately 1185 MWh/year which leads to more than 300 GWh/year for the 342 Swedish indoor ice rinks. LÄS MER
