Polish expeditions to Vestspitsbergen between 1956 and 1960 were organized in connexion with the Third IGY and its continuation. The main area chosen for scientific investigations was Hornsund, Vestspitsbergen, in which, at Isbjørnhamna, the main station was built (lat. 77° N., long. 15° 30′ E.). The areas covered by investigations were mainly southern and central parts of Wedel Jarlsberg Land and Torell Land, to the north of Hornsund, and the northern part of Sørkapp Land, to the south of Hornsund. Brief investigations were also carried out to the south of Van Keulenfjorden, in north-west Torell Land, and along the western, southern and eastern coasts of Sørkapp Land.
