Opis:
The article characterizes first general geological (lithological-stratigraphical) maps presenting Quaternary deposits in Northern Poland. These were the maps of territory of the Prussian partition, elaborated by German geologists from Prussian Geological Survey “Königlich Preussische Geologische Landesanstalt”. After Poland regained its independence they became a basis for many Polish geological publications. The article discusses the chronology and objectives of the main cartographic works of German geologists operating in the area of present-day Northern Poland (general and detailed geological maps) and briefly presents the methodology of geological mapping of lowlands at the scale of 1:25,000. The authors present initial results of the sheet inventory of the Prussian geological map at the scale of 1:25,000 owned by the Polish Geological Institute – National Research Institute (PGI–NRI). Quick search of Prussian map sheets is enabled with the created GIS data base which contains basic information about sheets, i.e. map title, year, author/authors, sheet title and topographic map designation. The applied relations between data and their spatial reference make it possible to dynamically generate section map and perform spatial analyses of any type. The multiuser geodatabase was created using ESRI and Oracle technologies. Until now the inventory covered the sheets available in the archives of the Marine Geology Branch of PGI–NRI in Gdańsk and the Pomeranian Branch of PGI–NRI in Szczecin. The article also presents examples of Prussian topographic and geological maps used to realize the objectives of the surface geology of Poland. Sheets of Prussian maps are a very valuable basis for elaboration of general and detailed Polish geological maps. Prussian maps make it possible to recreate the earlier geological, geomorphological and hydrographic picture of terrains which are now highly developed and antropogenically transformed. They are often used for the purpose of various time-spatial analyses, mostly to evaluate the dynamics and pace of erosional and accumulative coastal processes of the Southern Baltic coast. The maps of this type help to reconstruct and forecast the development of river mouths and to recreate the location of excavations and inactive open-cut mines of sand, gravel, clay, brown coal and amber. Old maps documenting the exact location of exploited deposits have practical application in geo-tourism.

Opis:
The coastline in the Jastrzębia Góra area can be divided into three major zones of general importance: a beach and barrier section, a cliff section, and a section protected by a heavy hydrotechnical construction. These areas are characterised by a diverse geology and origin, and hence different vulnerability to erosion. In addition, observations have demonstrated a different pace of erosion within each zone. Based on the results obtained by remote sensing methods (analysis of aerial photographs and maps), it has been determined that the coastline in the barrier area, i.e., to the west of Jastrzębia Góra, moved landwards by about 130 m, in a period of 100 years, and 80 m over about 50 years. A smaller displacement of the shoreline could be observed within the cliff. Between the middle of the twentieth and the start of the twenty-first centuries the shore retreated by about 25 m. However, in recent years, an active landslide has led to the displacement of the uppermost part of the cliff locally up to 25 m. Another issue is, functioning since 2000, a heavy hydrotechnical construction which has been built in order to protect the most active part of the cliff. The construction is not stable and its western part, over a distance of 50 m, has moved almost 2 m vertically downwards and c. 2.5 m horizontally towards the sea in the past two years. This illustrates that the erosional factor does not comprise only marine abrasion, but also involves land-based processes determined by geology and hydrogeology. Changes in the shoreline at the beach and barrier part are constantly conditioned by rising sea levels, the slightly sloping profile of the sea floor and low elevation values of the backshore and dune areas. Cliffs are destroyed by mass wasting and repetitive storm surges that are responsible for the removal of the colluvium which protects the coast from adverse wave effects. Presumably, mass movements combined with groundwater outflow from the cliff, plus sea abrasion cause destabilisation of the cliff protection construction.
