Shoreline dynamics of Calypsostranda (NW Wedel Jarlsberg Land, Svalbard) during the last century
Shoreline dynamics of Calypsostranda (NW Wedel Jarlsberg Land, Svalbard) during the last century A 6 km long stretch of the coast of Calypsostranda between Skilvika and Joseph-bukta, situated on the western side of Recherchefjorden, was investigated.
