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:
The article summarises results of studies on litter concentrations on the Polish sea shore. Origin, mechanism of transport and source of litter are discussed. The main part of the data has been based on litter quality and quantity investigation in post-storm marine sediments. Data were collected in surface sediments since 2001 and in fossil washover fans dated 1988–2000 in different locations on the coast. Litter has been divided according to the material, use, size and origin. Analysis of litter quantity on beaches after storm surges showed an annual increase. The heavier surge, the more debris and mixed litter appear on the coast. A large increase in the amount of litter has been observed after the storm in 2009. The average amount of litter per 1 m2 has increased from 1.5 in 2001 to 17.5 in 2020. Among litter there is still a similar share of fishery and ship waste. The biggest growth was observed in waste of consumable origin. Plastic litter, including anthropogenic waste left on beaches, has increased to 80% in recent years. Most waste occurred on the coast adjacent to the Vistula River mouth.

Opis:
The aim of the research was to identify the potential for the use of probability density functions (PDF) in modeling of near-surface wind speed. The approaches of Empirical Orthogonal Functions (EOF) and Canonical Correlation Analysis (CCA) are used in combination with 2-parametric Weibull distribution. The downscaling model was built using a diagnosed relationship between sea level pressure (SLP) patterns over Europe and the Northern Atlantic and estimated monthly values of Weibull parameters at 9 stations along the Polish Baltic Coast. The obtained scale (A) and shape (k) parameters make it possible to describe temporal variations of wind fields and their theoretical probability values. This may have further application in the modeling of extreme wind speeds for seasonal forecasting, climate prediction or in historical reconstructions. The model evaluation was done separately for the calibration (1971-2000) and validation periods (2001-2010). The scale parameter was reconstructed reasonably, while there were some problematic issues with the shape parameter, especially in the validation period. The quality of the developed models is generally higher for the winter season, due to larger SLP gradients, whereas the results for the spring and summer seasons were less satisfactory. Despite this, the 99th percentile of theoretical wind speeds are in most cases satisfactory, due to the lesser importance of the shape parameter for typical distributions in the analyzed region.

Opis:
The new method of a detailed morphodynamic registration of sandy beaches has been presented. The digital oriented photograms have been taken from a stabilised point at least once a day. Occasionally also more often, for example every hour during a storm cycle. The analyses of the photograms are performed in digital mode using special computer software. This digital beach monitoring of the Polish Baltic coast was initiated in summer 2002. The test fields in Polanka Redłowska within Gdynia and Chłapowo near Władysławowo were selected. The beach areas of the length of about 200 m along the shore were registered there. Selected examples of short-term changes of the beach relief were presented. A range of spatiotemporal transformations related to different periods (hours, days, months etc.) was demonstrated.

Opis:
Morphology of sea bottom of the Władysławowo area, from Karwia to Chałupy, has been studied based on the detailed digital bathymetric map prepared in a scale of 1:25 000 with isobaths every 0.25 m. A significant differentiation of the bottom relief has been observed, with the level changes up to 1-3 metres, mostly connected with the occurrence of specific systems of ridges and runnels. They are probably partly relict forms (fluvial and/or coastal?), changed to certain degree during the rapid stage of the Litorina transgression, and in partly forms created by the recent waves. Several types of the sea bottom surface, differing in pattern of morphological forms, have been recognised within inshore, near shore, and open sea (above 16 m depths) areas. The full knowledge of the origin and development of these relief forms requires further specialised research, currently carried out. Nonetheless, the already obtained picture of the sea bottom relief indicates an intensified abrasion of the offshore sea bottom, and an intensive, irreversible sweeping out of the sediments from the shore to the open sea, most probably by rip currents, at a distance up to several kilometres from the shore. It is in accordance with the results of a former large-scale (1:500) study of the sea bottom at the test field at Chłapowo, performed with the use of an integrated system of non-invasive and direct methods.

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.

As offshore market in Europe grows faster and faster, new sea areas are being managed and new ideas on how to use the sea potential are being developed. In North Sea, where offshore industry conducts intensive expansion since late 1960s, numerous wind farms, oil and gas platforms and pipelines have been put into operation following extensive research, including geotechnical measurement. Recently, a great number of similar projects is under development in Baltic Sea, inter alia in Polish EEZ, natural conditions of which vary from the North Sea significantly. In this paper, those differences are described together with some solutions to problems thereby arising.

Opis:
A population of Cerastoderma glaucum Poiret 1789 was studied in the Polish coastal zone (up to 3 Nautical miles) of the Baltic Sea within the Puck Bay and part of the Gulf of Gdańsk. The frequency (F) in the sheltered coastal zone of bays was high (65%), whereas at the exposed open coast of the Middle Pomerania it was lower (43%). Also, abundance in the Puck Bay and the Gulf of Gdańsk was over 3-fold higher than in the coastal zone of the Middle Pomerania. By means of classic statistical methods (essential tests) we proved the significance of differences between mean abundance at west and east transects in estuaries and between open coast and estuaries. The multivariate regression and classification trees (MR&CT) indicated that biomass and abundance of C. glaucum in the Baltic Sea were affected by the kind of bottom, whereas depth and distance to the bank influenced cockles' abundance and biomass in bays. The population's structure in the Puck Bay and the Gulf of Gdańsk was determined mainly by the depth. In the Wieprza River estuary only specimens from age group 1+ were found. On all the other studied profiles cockles lived up to 3 or 4 years and the dominant group was 2+. The highest mean width of shell was in the Słupia River estuary, and in the bays shell width increased from west to east. In comparison to the other bivalves inhabiting the discussed area, C. glaucum does not play an important role as food source for fish and other consumers but may serve as an indicator of environmental conditions.
Badano populację małża sercówki bałtyckiej Cerastoderma glaucum (Poiret, 1789) w polskiej strefie przybrzeżnej Bałtyku (do 3 Mm), oraz w Zatoce Puckiej i Zatoczce Gdyńskiej (część Zatoki Gdańskiej). Frekwencja dla strefy przybrzeżnej zatok była wysoka i wynosiła średnio F = 65%, a dla strefy przybrzeżnej Wybrzeża Środkowego tylko F = 43%. W strefie przybrzeżnej Zatoki Puckiej i Gdyńskiej zagęszczenie Cerastoderma było ponad 3-krotnie wyższe w porównaniu do masy mokrej w strefie przybrzeżnej Wybrzeża Środkowego. Przy użyciu klasycznych metod statystycznych (testów istotności) wykazano różnice w średnim zagęszczeniu pomiędzy profilami wschodnimi i zachodnimi w estuariach oraz pomiędzy otwartym wybrzeżem a strefami estuariowymi. Zastosowana metoda MR&CT (drzewa regresyjne) dla danych z Morza Bałtyckiego wskazała, że na biomasę i zagęszczenie Cerastoderma wpływ ma jedynie granulacja podłoża, natomiast na obszarze zatok na zagęszczenie wpływa głębokość, a na biomasę odległość od brzegu. Struktura populacji Cerastoderma glaucum zasiedlającej Zatokę Pucka i Gdańską jest determinowana głównie przez głębokość. Najkrócej sercówki żyły w estuarium Wieprzy, gdzie występowały wyłącznie osobniki z grupy wiekowej 1+. Na pozostałych badanych pod tym względem profilach małże te dożywały wieku 3 i 4 lat, z dominującymi starszymi grupami wiekowymi, głównie 2+. Badania szerokości muszli wykazały, że średnia szerokość muszli badanych Cerastoderma na obszarze Wybrzeża Środkowego była największa w estuarium Słupi, natomiast na obszarze zatok zasadniczo wzrastała z zachodu na wschód. W porównaniu do innych gatunków małży zasiedlających badany obszar, Cerastoderma glaucum, ze względu na niewielką liczebność, nie odgrywa większej roli ekologicznej oraz nie tworzy bogatej bazy pokarmowej dla ryb i innych hydrobiontów, może natomiast posłużyć jako organizm wskaźnikowy niekorzystnych zmian zachodzących w środowisku.

Opis:
Space-time variations in chlorophyll a (Chl a) concentrations in the surface water of upwelling regions along the Polish coast of the Baltic Sea were analysed. Carried out between 1998 and 2002 in the warmer season (from April till October), the measurements were targeted mainly at the Hel upwelling. Satellite-derived sea surface temperature (AVHRR) and Chl a data (SeaWiFS) were used. Generally speaking, the Chl a concentration increased in the upwelling plume, except along the Hel Peninsula, where two scenarios took place: a reduction in Chl a concentration in spring and an increase in autumn.

Opis:
Coastal upwelling often reveals itself during the thermal stratification season as an abrupt sea surface temperature (SST) drop. Its intensity depends not only on the magnitude of an upwelling-favourable wind impulse but also on the temperature stratification of the water column during the initial stage of the event. When a ‘chain’ of upwelling events is taking place, one event may play a part in forming the initial stratification for the next one; consequently, SST may drop significantly even with a reduced wind impulse. Two upwelling events were simulated on the Polish coast in August 1996 using a three-dimensional, baroclinic prognostic model. The model results proved to be in good agreement with in situ observations and satellite data. Comparison of the simulated upwelling events show that the first one required a wind impulse of 28 000 kg m−1 s−1 to reach its mature, full form, whereas an impulse of only 7500 kg m−1 s−1 was sufficient to bring about a significant drop in SST at the end of the second event. In practical applications like operational modelling, the initial stratification conditions prior to an upwelling event should be described with care in order to be able to simulate the coming event with very good accuracy.

Opis:
The surface water temperature in the Baltic Sea has been growing as a consequence of broader changes of the Earth’s climate, which contributes to the proliferation of natural bacterioplankton and new types of bacteria, such as Vibrio vulnificus, in the region. This pathogenic bacterium finds optimal conditions for growth primarily in warm brackish waters. Places particularly vulnerable to these bacteria include shallow Baltic coastal waters where the proliferation of Vibrio strains increases in summer. The growing temperature of coastal waters boost this phenomenon, posing a serious threat to human health and the coastal Baltic tourism. The BaltVib project implemented by marine microbiologists investigates the impact of the so-called “system engineers”, e.g. mussels, macroalgae, and seagrass, on the diversity and abundance of vibriosis. The research should help to develop strategies to mitigate the problem of excessive populations of vibriosis through nature-based solutions. In addition to environmental and health issues, public awareness of the phenomena and future threats are equally important and these are also addressed in the project. The article presents results of a survey conducted on the Polish coast involving 140 respondents interviewed concerning their awareness of the increasing population of pathogenic vibriosis. The survey helped to diagnose how local residents perceive the threat to human health posed by Vibrio vulnificus now and in the future, as well as possible impacts these bacteria might have on economic use of the coastal waters. The survey also investigated the level of acceptance for various methods used to mitigate negative environmental changes.
