  1. 1. Glacial erosion zonation : perspectives on topography, landforms, processes and time

    Författare :Anders Clarhäll; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : .... LÄS MER

  3. 2. Sedimentology and Geomorphology of Glacial Landforms in Southern Sweden : Studying the Landscape of a Melting Ice Sheet

    Författare :Gustaf Peterson Becher; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Glacial geology; Geomorphology; Sedimentology; Glaciology; Tunnel-valley; Glaciofluvial meltwater corridor; Murtoo; Småland;

    Sammanfattning : Ice sheets are disintegrating due to global warming. One factor controlling ice-sheet behavior is the processes active beneath the ice sheet. In particular, processes connected to glacial meltwater drainage are essential to understand ice-sheets behavior in a warming climate. LÄS MER

  4. 3. The role of tectonics, structures and etch processes for the present relief in glaciated Precambrian besement rocks of SW Sweden

    Författare :Magnus Johansson; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Landforms; morphotectonics; palaeosurfaces; GIS; digital elevation data; granite; deep weathering; saprolites; etchsurface; basins; structures; glacial reshaping; roche moutonnée; Naturgeografi; Physical Geography;

    Sammanfattning : In high latitudes, landscapes of low relief are known to contain residues of pre-glacial deep weathering, or etching, which testify to limited modification of the pre-glacial relief by the Pleistocene ice sheets. In this thesis landforms in all scales are classified according to their process of formation. LÄS MER

  5. 4. Exploring beneath the surface of glacial landscapes : Implementing and improving geophysical investigations in glaciated environments

    Författare :Hannah Watts; Peter Jansson; Benedict Reinardy; Darrel Swift; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Geophysics; Glacial Geology; Glaciers; naturgeografi; Physical Geography;

    Sammanfattning : The warming climate is having profound impacts on glacier dynamics and extents. To improve our predictions of future ice mass changes, we require an enhanced understanding of both past and present glacial processes. LÄS MER

  7. 5. 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
