| dc.description.abstract | This thesis considers the development of landforms observed in front of the icemass Storbrean on the Dovre plateau. Storbrean is located on permafrost, consist of cold ice, and have zero surface velocity. Still the forms resemble glacier striae, flutings and chatter marks which require sliding at the glacier – bed interface and materials in the ice to abrade and deposit. This raises the question of the origin of these forms, are they actively created below Storbrean today or are they relict? And if they are relict then how were they created? The thesis does especially focus on the possibility of a subglacial origin, and what subglacial conditions would be required to glacially create the forms observed. Through field observations and investigations of relevant theory the thesis concludes that it’s likely the landforms were created below a polythermal glacier and that Storbrean is not actively contributing to
landform development today. | nb_NO |
