  2. 1. Relict non-glacial surfaces and autochthonous blockfields in the northern Swedish mountains

    Author : Bradley W. Goodfellow; Arjen Stroeven; Clas Hättestrand; Johan Kleman; Krister Jansson; Adrian Hall; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; blockfield; chemical weathering; cosmogenic exposure dating; glaciated landscape; northern Sweden; periglacial geomorphology; relict surface; Physical geography; Naturgeografi; geografi med naturgeografisk inriktning; Geography; Physical Geography;

    Abstract : Relict non-glacial surfaces occur in many formerly glaciated landscapes, where they represent areas that have escaped significant glacial modification. Frequently distinguished by blockfield mantles, relict non-glacial surfaces are important archives of long-term weathering and landscape evolution processes. READ MORE

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

    Author : Jens-Ove Näslund; Sugden David; Stockholms universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

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

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

    Abstract : 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. READ MORE

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

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

    Abstract : 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. READ MORE

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

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

    Abstract : 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. READ MORE
