The aim of this paper is to attempt a first understanding of the synoptic weather conditions associated with soil frost occurrence on Marion Island. Specifically, the AA. hypothesise that soil frost is dominant under specific air circulation
patterns and is associated with clear skies. The study was conducted in the interior of Marion Island at Katedraalkrans in the polar desert habitat : scoria and black lava deposits almost completely unvegetated. Therefore this site allows for a direct
Fine scale variability in soil frost dynamics surrounding cushions of the dominant vascular plant species (Azorella selago) on sub-Antarctic Marion Island
