2007 was remarkable because of the beginning of the IV IPY 2007-2009. On this occasion a special conference organized by the Polish Academy of Science, Ministry of Science and Higher Education and Polish Committee for IV IPY was held in Warsaw in the Staszic Palace, the seat of the Polish Academy of Science, April 27.

The programme of the Polish research that will be carried out during the IV IPY was presented. During the II IPY (1932-1933) a Polish team stayed on Bjørnøya (Bear Island) collecting a 13-month long radiometeorological, geomagnetic and meteorological observation series. Polish participation in the III International Polar Year (International Geophysical Year) 1957-1958 was of particular significance. This was a very important period for Poland: the Polish Polar Station situated in the region of Isbjørnhamna in the Hornsund Fiord on Spitsbergen (Svalbard Archipelago) was created.

The Polish research programme accomplished during the III IPY assumed a year-long cycle of meteorological, glaciological, ionospherical, astronomical, permafrost and CO2 atmospheric observations. Moreover, during the polar summer research was carried out in geology, geomorphology, hydrology, botany, and zoology. The station built in Hornsund 50 years ago is still in use. At present it is a very modern interdisciplinary research centre of the Spitsbergen environment, and its existence enables education of research staff and intensive exploration of the region. The Polish research programme in the IV IPY undertakes research both in the Arctic and Antarctic and will be carried out on Spitsbergen, based at the station in Hornsund as well at seasonal stations and bases of Polish universities, and on the Western Antarctica – Henryk Arctowski Station on King George Island. In 2007 studies were carried out there of climate, active layer dynamics, periglacial phenomena, functioning of periglacial and glacial geoecosystems under the conditions of growing seasonal changes in climate. This subject is related to or is a part of international IPY projects (TSP and CALM II) coordinated by the IPA.

August 1-5 a conference was held in Longyearbyen (Spitsbergen) entitled Geodiversity of Polar Landforms organized on the occasion of IV IPY. The organizers of the conference were: IAG, Association of Polish Geomorphologists, A. Mickiewicz (University of Poznan, Poland), The University Centre in Svalbard (UNIS), Svalbard Science Forum, and the Geological Survey of Norway. On the occasion of the conference there was published the well-illustrated volume Landform Analysis in journal of the Association of Polish Geomorphologists, including 34 papers and communiqués as well as the field trip guide on Formation and remodelling of marginal zones for selected Spitsbergen glaciers. During the conference participants stayed at the Polish university stations: Kaffioyra (Nicolaus Copernicus University, Torun), Calypsobyen- Bellsund (Maria Curie-Sklodowska University, Lublin), Petuniabukta (Adam Mickiewicz University, Poznan) and Hornsund (Polish Polar Station of Institute of Geophysics, Polish Academy of Science). During the post-conference excursion on the SBB Horyzont II ship of Gdynia Maritime University, the participants were acquainted with the contemporary glacial, periglacial and littoral morphogenesis of the relief in central and western parts of Spitsbergen.

On October 29-30 a conference was organized by the Institute of Geophysics, Polish Academy of Science, in Warsaw presenting the works from the research project Structure, Evolution and Dynamics of Lithosphere, Cryosphere and Biosphere in the European Sector in the Arctic and Antarctic (A. Guterch). The results of the research were published in foreign and domestic publications, mainly in the journal Polish Polar Research (vol.25-28, 2004-2007, ISSN 0138-0338), edited by the Committee on Polar Research of Polish Academy of Science.
