The study includes comprehensive study of the geographical environment in the area of Polar Station of Maria Curie-Skłodowska University in Calypsobyen (NW part of Wedel Jarlsberg Land, Svalbard). Currently, studies have been carried out within research projects: - Dynamics of matter circulation in the polar catchment are a subject to deglaciation processes (Scottelva, Spitsbergen) (DYNACAT) - Morphogenetic and morphodynamics conditions of development of the coast of the NW part of Wedel Jarlsberg Land (Spitsbergen) in the late Vistulian and Holocene (MORCOAST) - Mechanisms of fluvial transport and sediment supply to Arctic river channels with various hydrological regimes (SW Spitsbergen) (ARCTFLUX)
