  1. 1. Implications of a rapidly thinning ice-margin for annual moraine formation at Gornergletscher, Switzerland

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Lukas Rettig; [2020]
    Nyckelord :Recessional moraines; Ice-marginal processes; Glacier retreat; Glacial geomorphology; Glacial sedimentology; Alpine glaciers; Swiss Alps; Earth and Environmental Sciences;

    Sammanfattning : This study examines genetic processes and climatological significance of annual moraine formation in the foreland of Gornergletscher, a large alpine-valley glacier located in the southern Swiss Alps. A particular focus is set on moraine ridges that have been forming between 2007 and 2019, a period when the glacier has been subject to accelerated retreat and pronounced frontal thinning. LÄS MER

  2. 2. 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.

  3. 3. Central Asian ice-marginal moraines of the global last glacial maximum : An analysis of topographic features affecting the glaciation pattern in the Tian Shan and Altai mountains

    Kandidat-uppsats, Stockholms universitet/Institutionen för naturgeografi

    Författare :Sonja Sandström; [2018]
    Nyckelord :Altaimountains; GeographicInformation System; Tian Shan mountains; water resources; marginal moraine; MIS 2; paleoglaciology;

    Sammanfattning : Glacial runoff from the Tian Shan and Altai Mountains is an important water resource, especially for people living in the arid areas of Central Asia. Measured water volumes from glaciers have decreased, and glacier area have shrunk with 50-90% since the Little Ice Age. LÄS MER

  4. 4. Hindens rev i tid och rum - att använda sig av museala samlingar i landskapsvård

    Kandidat-uppsats, Göteborgs universitet/Institutionen för kulturvård

    Författare :Ida Nilsson; [2014-08-20]
    Nyckelord :museum collections; research material; archive study; vegetational conditions; landscape conservation; repeat photography; repeat inventory;

    Sammanfattning : This thesis is created with the conscious aim of answering to whether it’s possible to utilize museum collections in landscape conservation. After the passing of the biologist Bengt M. P. Larsson a substantial quantity of unpublished research material was uncovered. LÄS MER
