Marion Island is a sub-Antarctic volcanic island with a cold, wet climate. Much of the interior of the island is bare, with vegetation only found at lower altitudes. No soil classification has yet been undertaken for the Island, and literature on its soils and pedogenesis is sparse. As part of a broader research project on Geomorphology and Climate Change the morphological, physical, chemical, mineralogical and biological properties of soils from seven terrestrial habitats on Marion Island were analysed. It was determined that pedogenesis has taken place on Marion Island. A relationship was observed between soils and terrestrial habitats. Soils were classified according to the World Reference Base (WRB) soil classification system as Histosols, Histic Andosols, Andosols and Regosols. Generalised soil profiles were constructed for each of the seven terrestrial habitats. The spatial distributions of soil types for the Island were predicted with the use of a GIS model and are presented, together with the implications of climate change for pedogenesis and soil distribution on Marion Island.
