Opis:
We studied the phenomena associated with the thrusting of ice onto the shore of the Szczecin Lagoon based on the occurrence of tree ice scars. The measurements concerned mostly the maximum height, length and width of ice scars on trees, and the distance of these trees from the shore in the period 2017–2022. It was observed that sheets of ice advanced up to 64 m inland, and piled to form hummocks reaching up to 4.3 m above the water level. These maximum values occurred mostly on eastern shores, which is where the highest numbers of damaged and broken trees were observed. This should be associated with the strongest and most frequently occurring wind blowing from the western direction in the winter-spring period. To the contrary, the lowest number of damaged trees were observed on the western shore. This is due not only to the lower frequency of wind blowing from the east, and the associated cooling (Ta < 0°C) and ice cover stabilization, but also due to the presence of extensive reed belts. Our results enable an indirect insight into the ice phenomena dynamics, especially in areas lacking systematic ice observations. Similar conclusions may be extended for all the sheltered basins as lakes or lagoons.

Polish Baltic Sea coast
Opis:
This article describe Polish coastal dunes and the factors influencing their development. The Polish coast is 500 km long and mainly exposed for a northerly direction. It is a part of the southern Baltic shore. The Polish coast is composed of mostly loose sand, till and peat. Because the coast hardiness is so weak, it is under constant threat from storm surges as well as human impact caused by rapid infrastructure development and the coastal protection measures put in place to try and protect it. These protection measures destabilize the natural coast dynamics and rebuilding process. Almost 85% of the shoreline is built up by sandy aeolian deposits and covered by different dune types. Among them are typical foredunes or inland dunes in eroded coastal areas. The second type of dune coasts are built up by land dunes, which appear on the coast as a result of sea erosion causing land regression. Sometimes dunes can be found over moraine deposits or in front of moraine old cliffs. Nowadays these habitats are heavily threatened by storm surges and human activity. In some places there is an accumulation that leads to new ridge developments. This article describes these issues with an emphasis on the present dynamics of Poland’s coastal areas.

Opis:
The present paper focuses on the evolutionary dynamics of ammonites from sections along the Russian Pacific coast during the midand Late Cretaceous. Changes in ammonite diversity (i.e., disappearance [extinction or emigration], appearance [origination or immigration], and total number of species present) constitute the basis for the identification of the main bio−events. The regional diversity curve reflects all global mass extinctions, faunal turnovers, and radiations. In the case of the Pacific coastal regions, such bio−events (which are comparatively easily recognised and have been described in detail), rather than first or last appearance datums of index species, should be used for global correlation. This is because of the high degree of endemism and provinciality of Cretaceous macrofaunas from the Pacific region in general and of ammonites in particular.

Opis:
This research examines the eutrophication process mainly by considering the chlorophyll-a concentration. A simple linear model was used to determine the correlation between Chlorophyll-a and dissolved inorganic phosphate (DIP). The research was carried out on river mouths in the north coast of Central Java. The results of the linear model show that the relationship between chlorophyll-a and DIP follows the logarithmic model with the log [Chloa] = 1.52 + 1.60 log [DIP], R2 = 0.55. The model suggests that the high concentration of chlorophyll-a is related to dissolved inorganic phosphate concentrations. On the basis of the sufficient of conclusive evidence for these variables, the study sites with high stresses from several anthropogenic sources had higher chlorophyll-a than the sites that are relatively far from river mouths and lands.

Opis:
The occurrence of lactic acid bacteria flora (LAB) was investigated on Ivorian fermented fish Adjuevan products produced with sea fish at different salt concentration (10, 15, 20, 25, 30%) according two traditional methods. LAB biodiversity was investigated using traditional culture-dependent method and culture-independent method (DGGE). LAB isolates were Lactobacillus fermentum 54%, Leuconostoc lactis subsp lactis 27%, Pediococcus pentosaceus 19% according method 1 and Pediococcus pentosaceus 61%, Lactococcus garviae 32%, Streptococcus diffi cilis 7% for method 2. The results of culture-independent method using DGGE patterns and sequencing of DNA bands revealed a higher number of lactic acid bacteria species even if the identification of several lactic acid bacteria species were not possible by traditional microbiological procedures. LAB were Lactobacillus delbrueckii subsp bulgaricus, Lactobacillus helveticus, Leuconostoc lactis, Lactococcus raffi nolactis. Microflora was influence by salt percentage and more by the method of fermentation used. The molecular method DGGE which used three primers Lac1, Lac2GC and Lac3 to study LAB biodiversity directly in the fermented fish matrix, have allowed us to get a more complete picture of the dominant lactic acid bacteria diversity in these fermented product Adjuevan.

The study was carried out in the wall of a cliff that formed as a result of erosional cutting in the western foreland of a moraine landform from the Pomeranian and Gardno phases (Upper Plenivistulian, Rowy-Ustka clifs; northern Poland). Individual lithostratigraphic units have been documented: glaciofluvial delta deposlts, Poddąbie Till, lacustrine-glacial Wytowno Formation (consisting of three facies: deltaic, lower diamicton, and upper diamicton), lacustrine deposits of the Orzechowo Formation with a thick peat layer, and aeolian series at the cliff crest. The Wytowno Formation deposits include the following lithologies: medium-grained sands, fine-grained sands, muddy sands, muds, silty clays, clays, varved clays, fine-grained multi-fraction deposits, and tills (Dębina Till). Very high inclination of the strata is the result of glaciodynamic deformation. The deposits were accumulated in a proglacial lake. They are characterized by mud and clay as well as sand and sand-muddy lithofacies. The vastness of the water body is evidenced by a considerable size of the delta, and by massive structures of the clay layers.

Opis:
The paper presented contains results of the latest studies on assessment of the vulner-ability of the Polish coast to sea-level rise, thus providing the synthesis, development and update of all current works in this field. Apart from a general description of the basic physical and socio-economic coastal characteristics, boundary conditions were defined for further studies on Poland's vulnerability to ASLR. For each of the four areas, into which the Polish coastal zone was divided, a synthesis of threats and vul-nerability to the expected SLR was carried out, taking into account characteristic elements and features of the regions. Basing upon two extreme scenarios of sea-level rise, i.e. ASLR1 with 30 cm/100 yrs (optimistic variant) and ASLR2 with 100 cm/100 yrs (pessimistic variant), the assessment and cost calculation of total protection measures of the endangered areas in the coastal zone related to their capital value to be lost was executed. Finally, it was found that the protective investments should mainly be undertaken on the west and east coasts, where economically justified. Because of limited funds, it is necessary to concentrate on particularly important and simultaneously strongly threatened regions. The detailed analysis of costs implies that the activities should be undertaken first on the coastal segments adjacent to Gdańsk and Szczecin, where vast agglomerations are located, with concentrated industry and related infrastructure, as well as centres of science and culture.

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 influence of climate change on coastal areas is indisputable. Natural or anthropogenic elements of the coastal zone often reveal unforeseen changes, not comparable with earlier observations. However, human activity is influenced by climatic events that affect settlements and local economies. This paper presents the increasing threat of climate change to world coastal safety with an emphasis on field research from the coast of the southern Baltic Sea. The main climatic factors that influence the land and shallow seas of the coastal zone are: wind, waves, storm surges, ice jams and flooding.We are forgetting about the relationship between these factors and parts of the affected environment.Acostly shore protection scheme in one area forces erosion in another. It is proposed not to analyse the environmental events on average; such scientific results do not provide the basis for calculating real land erosion. In this paper, it is argued that nature does not respect average values; we need to prepare for greater change due to the escalation of those factors affecting the coast.

Opis:
In this work long-term probability of occurrence of maximum sea levels in some points of Polish Baltic Sea coast, was determined. Use was made of multi-year series of measurement data on maximum yearly sea levels, and their probability distributions were determined. To the analysis Gumbel’s distribution and Pearson distribution of 3rd type as well as quantile methods and the highest credibility method, were applied. Kolmogorov test was used to examine conformity of the theoretical distributions with real random variable distribution. As results from the analysis, the highest sea levels of 1000- year return period can be expected in Polish ports of the west part of the coast , i.e. Kolobrzeg (750, 2 cm , i.e. 2,5 m above the average sea level) and Swinoujscie (723,6 cm) . Lower sea levels of the same return period can be expected in Ustka (720,2 cm), Wladyslawowo (709,7 cm) and Gdansk (716, 7 cm), respectively.

Opis:
Colonization successfully advanced various reforms in Africa that affected several practices on the continent. The various customs that have been affected include the land tenure system of British colonies in particular. An abundance of laws and policies were adopted with the sole aim of conserving the environment. These policies often clashed with indigenous interests and witnessed counter attacks as a result. Despite this, there is little information in the literature concerning how British land policies shaped their relations with the indigenous people, particularly the Asante. Based on a qualitative research approach, the current study uses Asante as a focal point of discourse in order to historically trace British land policies and how they, the British engaged with the people of Asante. From the discourse, it should be established that the colonial administration passed ordinances to mobilize revenue and not necessarily for the protection of the environment. In addition, the findings indicated that the boom in cash crops, such as cocoa and rubber, prompted Britain to reform the land tenure system. With the land policies, individuals and private organizations could acquire lands from local authorities for the cultivation of cash crops. We conclude that the quest to control land distribution caused the British to further annex Asante.
