  1. 11. 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.

  3. 12. 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

  4. 13. Reconstructing the Long-Term Mass Balance of Brewster Glacier, New Zealand, Using a Degree-Day Approach

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Rikard Palmgren; [2017]
    Nyckelord :Mass balance; DDM; climate indicator; glacier; New Zealand; Massbalans; DDM; klimatindikator; glaciär; Nya Zeeland;

    Sammanfattning : Varmare klimat är något som kontinuerligt påverkar glaciärer planeten över och har under det senaste århundrandet vidtagit en global ökning av negativa massbalanser. Denna trend kan bidra till variationer i havsnivån och orsaka problem med översvämningar över hela världen. LÄS MER

  5. 14. Meteorological Conditions on Nordenskiöldbreen Glacier, Svalbard (2009 – 2015)

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Niclas Bergman; [2017]
    Nyckelord :Svalbard; Nordenskiöldbreen; glacier; albedo; Svalbard; Nordenskiöldbreen; glaciär; albedo;

    Sammanfattning : Glacial environments in the Arctic are a much-studied topic as well as a field of research with strong influences regarding the current and future global climate of our planet. This report is focused on the meteorological conditions on Nordenskiöldbreen glacier from 2009-2015 and how they correlate with each other, the glacier surface and the surrounding terrain. LÄS MER

  7. 15. The behaviour of melt water within a glacial system

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Love Tingdal; Nils Ceder; [2017]
    Nyckelord :meltwater; percolation; ice lens; glacier; smältvatten; perkolation; islins; glaciär;

    Sammanfattning : A glacier contains of many different layers of different properties. Each layer is formed during a calendar year similar to tree rings and their layers. A glacier has two different zones, the first one referred to as accumulation zone, where the addition of snow exceeds the loss of snow. LÄS MER
