Abstract. Archival maps are an invaluable source of information on the state of glaciers in polar zones and are very often basic research material for analysing changes in their geometry. However, basing a reliable comparative analysis on them requires they be standardised and precisely matched against modern-day cartographic materials. This can be achieved effectively using techniques and tools from the field of Geographic Information Systems (GIS). The research objective was to accurately register archival topographic maps of the area surrounding the Hornsund fjord (southern Spitsbergen) published by the Polish Academy of Sciences, and to evaluate their potential for use in studying changes in the geometry of glaciers in the western part of the Sørkapp Land peninsula in 1961–90. Comparing the 1961 and 1990 data, glacier surfaces lowered by about 80–85 m for the largest land-terminating glaciers of the peninsula, and by up to more than 90 m for tidewater glaciers (above the line marking their 1984 extents). The dataset is now available from the Zenodo web portal: https://doi.org/10.5281/zenodo.4573130 (Dudek and Pętlicki, 2021).

Short summary
In our research we evaluate the potential of archival maps of Hornsund fjord area, southern Spitsbergen, published by the Polish Academy of Sciences for studying glacier changes. Our analysis concerning glaciers in the western part of the Sørkapp Land peninsula revealed that in the period of 1961–1990 a maximum lowering of their surface was about 80–85 m for the largest glaciers terminating on land, and over 90 m for glaciers terminating in the ocean (above the line marking their 1984 extents).
