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

    Författare :Andreas Johnsson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mars; Svalbard; Spitsbergen; periglacial; ice; permafrost; Earth-analogues; terrestrial analogues; geomorphology; landforms; solifluction; debris flow; gully; craters; cold-climate;

    Sammanfattning : 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.
