The Polar Station of the University of Nicolaus Copernicus is located in the western part of the Oscar II Land, in the northern part of the coastal Kaffiøyra Lowland which is closed by the Forlandsundet from the west. The undertaken research included almost all components of the geographical environment. Scientific programs put pressure on research in glaciology, glacial geomorphology, permafrost and periglacial processes, as well as climatologic and botanical studies. Since 1995 glaciological research and the studies of permafrost of various ground types and their seasonal thawing, as well as meteorological observations have been the major issues on the research agenda. Glaciers pose the dominating feature of the Kaffiøyra region. Since the 19th century their area has decreased by about 30%. Thus, one of the main scientific issues studied there is the course and the reasons for the change in the glaciers’ range. This can be achieved by studying mass balance of the glaciers. Presently, mass balance of four glaciers is studied: the Waldemarbreen, the Irenebreen, the Elisebreen and the Aavatsmarkbreen. 39 The research includes both the summer balance (ablation and outflow from the glaciers) and the winter snow accumulation. The detailed research plans also refer to two large glaciers which end up in the sea. Those are the Aavatsmarkbreen in the north and the Dahlbreen in the south of the Kaffiøyra. Currently, subaquatic glacial relief of the bays in the Forlandsundet region is under scrupulous investigation. The results of the research can be obtained from the station’s website (www.stacja.arktyka.com), from the publications by the World Glaciological Monitoring Service (WGMS- IAHS), as well as the website of the Circumpolar Active Layer Monitoring (CALM- IPA). The research carried out in the N.Copernicus University Polar Station has enabled numerous scientists of most specialties of the Earth sciences (glaciology, climatology, hydrology, geomorphology, pedology and botany) to collect material for numerous papers, including master and doctoral theses. Scientific attractiveness of the Kaffiøyra’s geoecosystem has been appreciated by scientists from various scientific centres in Poland and elsewhere, who take part in interdisciplinary expeditions organized every year. The most Polish polar research in the north-west Spitsbergen is based on the N.Copernicus University Polar Station Once the station has had an extension addend, it can host 10-15 people at any one time. The new section of the station is 32 sq. m downstairs and 24 sq. m upstairs. This includes a study, a workshop, a bedroom as well as two bedroom entresols. The extension is connected with the old section of the station, which includes a living room and a bedroom, but there is also a separate entrance to the new part of the station. Additionally, the station gained extra storage floor, a laboratory, a bathroom, as well as a garage to keep boats, snowmobiles and engines. All together the station now has about 100 sq. m. The station is used 3 to 4 months annually, but it is possible to stay there for as long as a whole year. It is equipped with necessary technical facilities, motor-generators, solar panels, motorboats and snowmobiles. More important measurement equipment includes: a weather station with the basic measuring instruments (the measurements conducted since 1975); automatic weather stations (with the measurements taken at any intervals); limnigraphs and loggers installed in the selected watercourses (measurements of water levels, flow rates and the selected physicochemical features of water since 1975); a system of ablation poles installed on the glaciers; ice drills; loggers for measuring ground temperatures and ice temperatures, and others. The extension of the station in 2007 enabled larger groups of scientists to work and conduct research. The fact that both the living and laboratory space has been enlarged is especially important, as the station is often visited by scientists from all over the world. As a result, the extension will make it possible to intensify current international contacts, as well as start new co-operation projects in the Kaffiøyra region.
