Morphological feattures of ice wedge polygons in arctic zone.
Kysilka, Tomáš ; Křížek, Marek (advisor) ; Treml, Václav (referee)
Morphological features of ice wedge polygons in arctic zone Abstract This bachelor thesis deals with the subject of ice-wedge polygons including theirs morphological characteristics and conditions prerequisite for their creation. The paper states the conditions which allow and inhibit frost cracking of the ground. First part presents the conclusions of scientific literature published on the topic of permafrost, frost cracking, ice- wedges and ice-wedge polygons. Consequently the paper discusses the relation of ice-wedge polygons morphology to climate and lithology. Further the thesis analyzes morphological characteristics of ice-wedge polygonal net localized at southwest part of Banks Island, Canadian Arctic Archipelago. Acquired data and conclusions are confronted with published periglacial literature. Keywords: ice-wedge, ice-wedge polygons, frost cracking, permafrost, Banks Island, arctic zone
