  1. 1. Cold-climate landforms on Mars and Earth-analogues in Svalbard

    Author : Andreas Johnsson; Göteborgs universitet.; Gothenburg University.; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mars; Svalbard; Spitsbergen; periglacial; ice; permafrost; Earth-analogues; terrestrial analogues; geomorphology; landforms; solifluction; debris flow; gully; craters; cold-climate;

    Abstract : Periglacial landforms on Earth reflect cold-climate conditions and are intimately related to processes due to the presence of ground ice and perennially frozen ground, permafrost. The overall objective of this thesis is to investigate the potential of Svalbard as an analogue to Mars cold-climate landforms, and explore past and present processes and surface conditions on Mars by inference from morphological counterparts in Svalbard.

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

    Author : Magnus Johansson; [2000]
    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

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

    University dissertation from Stockholm : Stockholm University

    Author : Jens-Ove Näslund; Sugden David; [1998]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Antarctica; Basal temperature; Dronning Maud Land; Erosion; Escarpments; Glacial landforms; Ice Sheets; Ice sheet modelling; Landscape development; Palaeosurfaces; Radar; NATURAL SCIENCES Earth sciences Other earth sciences; NATURVETENSKAP Geovetenskap 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. 5. Glaciodynamics, Deglacial Landforms and Isostatic Uplift during the last Deglaciation of Norrbotten, Sweden

    University dissertation from Department of Geology, Lund University

    Author : Mattias Lindén; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Sedimentologi; Sedimentology; Geologi; physical geography; Geology; glaciotectonic; thrust stacking; deforming bed; ribbed moraine; Niemisel moraine; De Geer moraine; isostatic uplift; glaciodynamics; deglaciation; klimatologi; kartografi; marklära; Fysisk geografi; geomorfologi; geomorphology; cartography; climatology; pedology;

    Abstract : The aim of this thesis was to reconstruct the glaciodynamics, deglacial landforms, isostatic uplift and to date the deglaciation. Glaciodynamics and deglacial landforms were focused on to provide a process and depositional model for De Geer moraine and Niemisel moraine and to reveal their internal and spatial relationship, based on detailed sedimentological and structural investigations.
