  1. 1. Processes of lateral moraine formation at a debris-covered glacier, Suldenferner (Vedretta di Solda), Italy

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Monika Rabanser; [2019]
    Nyckelord :Lateral moraines; Moraine genesis; Moraine stability; Debris-covered glaciers; Clast shape; Alps; Sedimentology; Glacier fluctuations; Earth and Environmental Sciences;

    Sammanfattning : Lateral moraines are key features of glacial landscapes in high-alpine mountain areas. Research on lateral moraine formation is mostly limited to clean-ice glaciers; lateral moraine formation at the margins of debris-covered glaciers is currently poorly understood in an Alpine and sedimentological context.

  2. 2. Glacial history of the upper Drac Blanc catchment (French Alps)

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Felix Martin Hofmann; [2018]
    Nyckelord :Physical Geography; 10Be exposure dating; structure-from motion; geomorphological mapping; moraine; equilibrium line altitude; Alps; Earth and Environmental Sciences;

    Sammanfattning : Glacier advances in the Écrins massif (French Alps) during the Late Glacial and the Early Holocene are poorly constrained. Based on field observations, a high-resolution digital elevation model and an orthophoto, glacial landforms in the upper Drac Blanc catchment were mapped. LÄS MER

  3. 3. Investigating methods for identifying paleo surge-type glaciers or highly dynamical ice flows in Trygghamn, west Spitsbergen

    Master-uppsats, Stockholms universitet/Institutionen för naturgeografi

    Författare :Åsa Wallin; [2016]
    Nyckelord :;

    Sammanfattning : Surge-type glaciers exhibit a cyclic behaviour with an ice mass increase in the reservoir area during the inactive, quiescent phase and a rapid transportation of ice during the active, surge phase. In order to interpret the effects of climate change correctly it is important to distinguish between advances of surge-type glaciers and those of ‘normal’ glaciers, caused by climatic fluctuations.

  4. 4. Long-term glacier mass balance of Nordenskiöldbreen, Svalbard

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Sara Wiklund; [2016]
    Nyckelord :Mass balance; climate change; glacier; Svalbard; Massbalans; klimatförändring; glaciär; Svalbard;

    Sammanfattning : The global warming that’s taking place have an impact over the Earth and the glaciers on Svalbard are undergoing rapid changes as a result. The annual air temperature has been rising on Svalbard since the early 1900’s and in a climate projection expected temperatures continue to rise. LÄS MER

  5. 5. External Conditions Effects on the Self-Organised Criticality of the Calving Glacier Front of Tunabreen, Svalbard

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Pontus Westrin; [2015]
    Nyckelord :Calving; calving model; self-organized criticality; glacier dynamics; Tunabreen; Kalvning; kalvningsmodell; self-organized criticality; glaciärdynamik; Tunabreen;

    Sammanfattning : Mass balance processes in glaciers are important for determining the growth or retreat of ice. Calving, the mechanical breakage of ice bergs from a glacier front, is a poorly understood phenomenon. This process has great importance to the mass balance of many glaciers, for example on Antarctica and in the Arctic. A recent paper by Åström et al. LÄS MER
