    Sammanfattning : The overall aim of this thesis is to develop and exemplify the use of ground-penetrating radar (GPR) within the field of glaciology. The main focus is on the spatial distribution of snow in Dronning Maud Land, East Antarctica. LÄS MER

  3. 2. Ice Sheet, Climate, and Landscape Interactions in Dronning Maud Land, Antarctica

    Författare :Jens-Ove Näslund; Sugden David; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Antarctica; Basal temperature; Dronning Maud Land; Erosion; Escarpments; Glacial landforms; Ice Sheets; Ice sheet modelling; Landscape development; Palaeosurfaces; Radar; Other earth sciences; Övrig geovetenskap; naturgeografi; Physical Geography;

    Sammanfattning : The impact of glaciers and ice sheets on the subglacial landscape are of fundamental importance for studies of glacial history and landscape development, both in previously glaciated areas and in areas that are glaciated today. The thesis concerns the present and past erosive capacity of the ice sheet in Dronning Maud Land, East Antarctica. LÄS MER

  4. 3. Interference in Global Positioning System Signals and its Effect on Positioning and Remote Sensing

    Författare :Oscar Isoz; Oliver Julien; Luleå tekniska universitet; []
