Opis:
The following paper presents the problem of archaeological sites located on cliffs on the Southern Baltic Sea shore. This article discusses issues related to a necessity of solving the problem of this kind of research, related to methodological, as well as documentation and preservation standards based on preliminary results of the project conducted in Bagicz area (Ustronie Morskie commune). In this region four new structures were noted on a cliff surface. The key to understand the situation of archaeological sites located on a cliff areas is the knowledge of the processes related to their formation and activity. All of them have a huge impact for the state of preservation of the cliff, however they have various intensity level depending on the part of the Baltic Coast.

Opis:
Wolin in its early medieval history is inextricably linked to the using of water routes and shipbuilding tradition. Even as a town in the early stage of its development, has merged in itself influences of many cultural circles, which can be traced today by examining an archaeological artefacts. With a view to this phenomenon, the aim of this article is the presentation and analysing of construction of 10th century atypical hull fragments of the early medieval clinker-built boats from the archaeological site no. 3 in Wolin. Examined relics consists of four constructional groups – keel made of pine wood, upper strakes with oarports, planks of unusual cross-sectional shape and these with painted external side. They are a part of a set of 80 shipbuilding elements secondary used in the constructions of harbour quays, recorded during archaeological excavations conducted in 2012-2013. The whole observation is embedded on the wide comparative background enabling indication of similar objects – e.g. the finds discovered off the coast of the south Baltic zone and today’s Denmark, Norway and Sweden. Furthermore, the study aims to emphasize the high research value of the heterogeneous set of secondary used planks. On the basis of the observed technical aspects such as raw material, caulking, planks cross-sections, holes for the oars or treatment of the outer sides, there was noted many similarities to the wrecks characteristic for both the lands dominated by Slavs and Scandinavians. Thus, we are able to observe the specificity of the nautical craftsmanship created by two cultural elements. Visible technological diversity of relicts found in Wolin, undoubtedly legitimizes us to apply to this set the assertion about a ‘transregional’ idea existing in early medieval shipbuilding.

Opis:
During the construction of mathematical models for mapping hydrogeological conditions it is necessary to apply simplifications, both in the geological structure and in hydrogeological parameters used. The present note discusses problems surrounding the mapping of glaciotectonic disturbances that occur in the northern part of Wolin Island (northwest Poland). For this part of the island, a direct outflow of groundwater towards the Baltic Sea basin has been determined on the basis of geophysical survey results. An important feature in the hydrogeological conditions here is the isolation of groundwater from both the Baltic Sea and Szczecin Lagoon by clay with a Cretaceous xenolith. Such a geological structure explains the presence of perched water at considerable heights in zones close to the cliffs, without any significant hydraulic connection with surrounding reservoirs. Hydrogeological conditions of Wolin Island have been modelled using the Visual MODFLOW package v.4.2. In the vertical section, these conditions can be simplified to one aquifer (Pleistocene-Holocene), in which two aquifers can be distinguished. In a large part of the island, these remain in mutual hydraulic contact: layer I – upper, with an unconfined aquifer, and layer II – lower, with a confined aquifer, locally an unconfined one. The schematisation of hydrogeological conditions adopted here has allowed to reproduce present groundwater dynamics in the study area.

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.
