  1. 1. Mass Balance of the High-Arctic Glacier Nordenskiöldbreen, Svalbard, in a Changing Climate

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

    Författare :Maja Gustavsson; [2019]
    Nyckelord :Mass balance; glacier; Nordenskiöldbreen; climate change; Massbalans; glaciär; Nordenskiöldbreen; klimatförändringar;

    Sammanfattning : Melting glaciers are the major contributor to sea level rise. Glaciers are sensitive indicators of climate change and current experience strong developments in a rapidly warming Arctic environment. LÄS MER

  2. 2. Cold Surface Layer Dynamics of Storglaciären, Northern Sweden 2009-2019

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Shunan Feng; [2019]
    Nyckelord :Storglaciären; cold surface layer; cold-temperate transition surface; polythermal glacier; Storglaciären; kallt ytskikt; kall-tempererad is; polyterrmal glaciär;

    Sammanfattning : Storglaciären is a sub-Arctic polythermal glacier in northern Sweden. Twenty years' monitoring of thecold surface layer found that it has lost one third of its total volume of cold ice with an average thinningrate of 0.80 ± 0.24 m·a-1 for the period of 1989-2009. LÄS MER

  3. 3. Different generation of controlled moraines in the glacier foreland of Midtdalsbreen, Norway

    Master-uppsats, Stockholms universitet/Institutionen för naturgeografi

    Författare :Xavier Allègre; [2018]
    Nyckelord :Glacial sedimentology; glaciology; geomorphology; palaeoenvironmental reconstruction;

    Sammanfattning : A series of small mounds (< 3m) were sampled in the foreland of Midtdalsbreen outlet glacier, southern Norway. These landforms were interesting, especially at site number 1 because they were located very close to a higher Little Ice Age (LIA) moraine (> 5 m), thereby informing the dynamic of the glacier after the LIA at this location.

  4. 4. Estimation of Relative Seismic Velocity Changes Around Katla Volcano, Using Coda in Ambient Seismic Noise

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Frida Jonsdottir; [2018]
    Nyckelord :Katla volcano; Iceland; ambient seismic noise; coda waves; relative velocity variations; Katla vulkan; Island; omgivande seismiskt brus; codavågor; relativa hastighetsvariationer;

    Sammanfattning : Relative seismic velocity variations in the Earth’s crust can be estimated by using ambient seismic noise records from a pair of stations. Velocity variations can be caused by stress perturbations in the subsurface. Therefore, information on stress changes in the crust can possibly be retrieved from measured velocity variations in the medium. LÄS MER

  5. 5. The Ability of Regional Climate Models to Simulate Weather Conditions on Nordenskiöldbreen, Svalbard

    Kandidat-uppsats, Uppsala universitet/Luft-, vatten och landskapslära; Uppsala universitet/Luft-, vatten och landskapslära

    Författare :Malin Andersson; Erica Erikson; [2018]
    Nyckelord :Regional climate models; automatic weather station; glacier; Svalbard; Regionala klimatmodeller; automatisk väderstation; glaciär; Svalbard;

    Sammanfattning : In this project, we analyse the ability of two regional climate models to simulate meteorological conditions on Nordenskiöldbreen, a glacier in Svalbard. To do so, regional climate model output is compared with in situ measurements from an automatic weather station. LÄS MER
