Opis:
This paper presents results of the investigation carried out in frame of research project of Institute of Meteorology and Water Management Maritime Branch in Gdynia (IWM-MB) in the y ear 2000. The goal of the project was to determine the conformity of the sea current forecasts for the layer 8 - I 2 meters of the open sea part of the Southern Baltic Sea, as produced by the hydrodynamic model of the Baltic Sea- HIROMB [5}, with the measurements. Contrary to the results of previous experiments as in the case of the POLRODEX ones [7, 8, 9}, during present study it was expected to detect behaviour of the model far from the influence of the boundary like coastline as well as bottom friction in the shallow water areas. The analysed data were collected during five routine cruises of r/v Baltica organized by IWMMBsince February until September I999 [10], when cruise track started/rom the Gdansk Deep, next along the northern border of the Polish EEZ, ending in the Bomholm Deep area usually. On the basis of the current vectors recorded by means of the ship mounted ADCP as the 250 m average values in the layer 7.5 to 12.5 meters, mean values related to the model grid have been calculated and statistically assessed. These mean vectors have been used for compan·son of forecasted values. Consequently, the sets of values of the differences between measured and predicted currents were statistically evaluated both regarding the direction and the module of the currents as well as the current vector components (Vx, Vy) separately.

Opis:
In the course of fieldwork based on geological and landslide mapping and spatial analyses of map information at least 2 types of landslides were identified. Type I: simple landslides developed in homogeneous and undisturbed rocks, for instance – loams, clays and sands. This type of landslide includes many examples developed mainly on the stretch (segment of the studied area) approximately between 132.25 and 133.50 km and 128.50 and 129.50 km of the Polish coastline. Type II: complex landslides in which the movement and displacement of rock masses occurs under complex geological and hydrogeological conditions. The complex factors are determined by phenomena such as glaciotectonics, discontinuities of rock layers and thrust zones; the slip surface occurs at considerable depths, and sometimes several slip surfaces can be distinguished. These landslide types are located in the vicinity of Jastrzębia Góra and Rozewie, near km 134 and 131.5. Prediction of the formation of this landslide types is difficult. Even if long-term observations are available, the mass movement, variable over time, is difficult to interpret. It is clear that the changes are continuous, but occur with varying intensity. Proper recognition of the types of mass movement is crucial to establishing the appropriate methods to prevent their development.

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:
The genesis of the Vistula Spit (Southern Baltic Sea) in the Postlitorina period is regarded as occurring by gradual addition of successive dune ridges along the entire length of the form. Based on the degree of soil profile development and radiocarbon dating of organic sediments three main stages of aeolian processes are usually recognized. GIS analysis of a digital elevation model (DEM) and thermoluminescence dating of dune sand supports the model of progressive development of dune ridges, and has identified four periods of intense aeolian activity. These were established 5860–5400, 1930–1610, 1200–900 years ago from the present, and from 500 years ago.

The ar ti cle pres ents the re sults of a de tailed study of the geo log i cal struc ture of the £eba Bar rier in the R¹bka crosssec tion (South ern Bal tic, Po land). The bar rier sep a rates Lake £ebsko from the Bal tic. Five sed i men tary com plexes were dis tin guished there (M2–M6). The spa tial vari abil ity of the grain-size dis tri bu tion was ex am ined and suc ces sion stages of the mol lusc fauna oc cur ring in the in di vid ual sed i men tary com plexes were dis tin guished. Ra dio car bon dating was used to es tab lish the age of the most im por tant events dur ing the pro cess of for ma tion of the bar rier, which took place in the course of sev eral rel a tive sea-level changes. The first sed i men tary com plex (M2) at R¹bka is connected with the sec ond ingression (i2) of the Bal tic Sea (ca. 6,700–6,000 14C years BP), sea-level sta bi li za tion (6,000–5,500 14C years BP), and at last sea-level low er ing (5,500–5,000 14C years BP) in the re gion of the Gardno-£eba Coastal Plain. The sed i men tary com plex M3 de vel oped in a la goonal en vi ron ment when the bar rier was sit u ated north of its pres ent po si tion (5,000–3,000 14C BP). The next low er ing of the sea-level made the la goon shal lower and caused the emer gence of small but al ready subaerial stretches of bar rier land with a fresh wa ter fauna in the north (4,880±40 14C BP). With the next ingression stage (i3), which took place be tween 4,500 and 3,000 BP, the bar rier shifted to its pres ent-day po si tion and the la goon changed into a fresh wa ter lake. From 3,000 to 1,700 14C BP fos sil soil and peats de vel oped on the bar rier sur face as a re sult of an other sea-level low er ing. The last ingression stages (i4 and i5), youn - ger than 1,700 BP, built up the bar rier, prac ti cally in its to day’s lo ca tion (sed i men tary com plexes M4 and M5). The youn gest sed i men tary com plex (M-6) is rep re sented by pres ent-day beach sands.

Opis:
This paper summarizes four years of geological research in the Pomerania Bay and Oder Bank. As a result of the synthesis of new and archival data,we have compiled maps, cross-sections and models depicting the geological structure of the Quaternary and its basement, and the relief of structural surfaces. Two main seismostratigraphic sedimentary complexes are distinguished. The first corresponds to Pleistocene glacial and interstadial deposits. The second one is composed of Late Glacial and Holocene lacustrine-swamp and marine sediments. The outline of geochemical condition of the sea bottom is also presented. The content of the elements is always below the acceptable concentration and the origin of the elements is geogenic. Special attention has been given to mineral resources on the bottom surface and to documenting deposits of sand containing heavy minerals. The characterization of areas with sands suitable for beach nourishment and valorization of deposits and prospective areas have also been of great importance. The history of the development of the geological structure and palaeogeography of the area is the summary of the results.

Opis:
The paper presents the results of the first OSL dating of glaciofluvial and ice-marginal lake sediments which occur between end moraines of the Słupsk Bank and the Polish coast. The sand and gravel of glaciofluvial deltas on the Słupsk Bank were deposited most likely during a period from 14.3 ±1.2 to 16.6 ±1.4 ka ago. The deposition of silty-sandy sediments of the ice-marginal lake is dated at 14.51 ±0.81 and 14.6 ±1.4 ka years. Likewise, dates ranging from 13.74 ±0.84 to 16.70 ±1.1 ka obtained from low sandy ridges, related to the southern range of the ice-marginal lake in the Gardno-Łeba Lowland, indicate the most likely timing of their deposition. It can be concluded that a short stop of the ice sheet on the Słupsk Bank took place approximately 15.2 ka ago, which could be correlated with the position of the ice sheet front in central Skåne and in northern Lithuania at that time. Older and younger results were also obtained, except the dates mentioned above. The older ages show little sunlight exposure of sediments during their deposition. The younger dates indicate a marine origin of the sediments and show that some parts of glaciofluvial sediments were redeposited and exposed to sunlight at a later stage, most probably when dead-ice blocks were melting.
