    Opis:
    Scanning electron microscopy was employed for the investigation of bacteria living on sand grains in a sandy marine beach in the Gulf of Gdansk (southern Baltic Sea). Bacteria colonize the sand grains; individual topography and shape of the grains were decisive for the colonization. Grains of diverse topography characterised by a great irregularity of shape were preferred, and protected surface sites were favoured. Many of the attached bacteria were found to produce polymer secretions; entire colonies attached by means of polymer nets were observed. A significant morphological diversity of bacteria in the vertical profile of the beach was determined. Bacteria inhabiting the sand grains showed the ability to reproduces.
    W pracy przedstawiono wyniki badań dotyczących bakterii kolonizujących ziarna piasku plaży morskiej zlokalizowanej w rejonie Sopotu. Próby piasku pobierano z morza z odległości około 1,5 m od linii brzegowej (st. 1), z linii brzegowej (st. 2), środkowej części plaży (st. 3) oraz wydmy (st. 4). Przy użyciu mikroskopu skaningowego badano rozmieszczenie bakterii na ziarnach piasku, mechanizm ich adsorpcji do powierzchni ziaren piasku, zróżnicowanie morfologiczne i wymiary oraz ich zdolność do rozmnażania. Badania te wykazały, że bakterie maja zdolność do selektywnego kolonizowania ziaren piasku preferując głównie osłonięte i nieregularne powierzchnie (szpary, szczeliny, wklęśnięcia, fałdy, rysy). Wiele komórek bakterii kolonizujących ziarna piasku tworzyło charakterystyczne struktury włókniste, za pomocą których organizmy te trwale wiązały się z podłożem. Wykazano istotne zróżnicowanie morfologiczne bakterii na poszczególnych stanowiskach badawczych. Wiele bakterii zaabsorbowanych do ziaren piasku charakteryzowało się zdolnością do rozmnażania.

    Opis:
    Od 2016 r. we Wrocławiu powstało kilkanaście beach barów. Większość z nich zlokalizowano nad rzeką. Ich model przestrzenny (a także biznesowy), oparty na skojarzeniach zawartych w samej nazwie, kreujący przestrzeń o dużej atrakcyjności skłonił autora do objęcia ich badaniami. Celem przeprowadzonych badań było poznanie i ewaluacja stosowanych w beach barach sposobów ożywiania przestrzeni, przyciągania i zachęcania ludzi do spędzania tam czasu, a tym samym zrozumienie działania tych miejsc jako przestrzeni. Punktem wyjścia obserwacji i badań było założenie, że beach bary są rodzajem przestrzeni podobnych do miejskich przestrzeni publicznych, co z jednej strony pozwala sprawdzić, czy mogą one odgrywać taką rolę, a z drugiej daje możliwość potraktowania ich jako lustra, w którym pokazane zostanie to, czego miejskie przestrzenie publiczne nie zapewniają. Przyjęta metoda polegała na ciągłej obserwacji, dla której głównym punktem odniesienia była kilkudziesięcioletnia praktyka projektowa i realizacyjna amerykańskiej organizacji non-profit „Project for Public Spaces”. Zgodnie z tym podejściem ocena dotyczyła czterech sekcji: dostępność i połączenia, komfort i wizerunek, funkcja i działanie oraz wartość społeczna. Beach bary są przestrzeniami proponującymi urozmaicone formy spędzania czasu, zapewniają różnorodną, bogatą ofertę i dają możliwość korzystania z różnych rodzajów aktywności, a także umożliwiają użytkownikom dużą swobodę zachowania.
    Since 2016 several beach bars have been opened in Wrocław. Most of them were located by the river. The study was inspired by their spatial (and also business) model which relies on creating places of great attractiveness and bases on associations contained in the name itself. The research strived at learning and evaluating the ways of bringing the space to life, attracting and encouraging people to spend their time there, and thus at understanding how these places work as a space. The starting point for this observation and research was the assumption that beach bars are a type of space similar to urban public spaces. On the one hand, it makes it possible to see whether they can play such a role, while on the other it allows to treat them as a mirror which can reveal what urban public spaces are unable to provide. The adopted method consisted of a continuous observation. The long-standing practice in designing and implementing projects by the American non-profit organization “Project for Public Spaces” provided the main reference point for this study. According to this approach, the evaluation referred to four parameter groups: access and connections, comfort and image, function and action, and social value. Beach bars are spaces offering varied forms of leisure, they provide a diverse, rich offer and give an opportunity to enjoy various types of activities. They also give users a great freedom of behavior.

    Opis:
    The littoral fauna of Maltese sandy and shingle beaches is generally regarded as impoverished and consequently of little conservation interest. The fauna of three sandy and three shingle beaches was systematically sampled by coring, standardised searching and pitfall traps. Diversity and population density were highest at the surface for sandy beaches, but were highest below the surface for shingle. The two beach types had distinct suites of species and individual beaches were faunistically distinct. Maltese sandy and shingle beaches are of conservation importance for their habitat-restricted species, some of which have limited local and regional distributions, and are internationally protected.

    Opis:
    Beach sediments from two beaches at the Polish coast of the Baltic Sea were collected and analyzed. The sediments were collected in two seasons – winter and summer – at two stations, depending on the influence of the sea water on the examined sediments. At each station, surface sediments (0-5 cm) were collected as well as sediments at the depth of 10-15 cm. The results of the conducted tests reveal, that anthropopressure, the depth where the collected sediments were taken and the direct influence of the sea water on the sediments have impact on the chemical composition of beach sediments and their food quality for the inhabiting psammon. The conducted tests disclose that there is more organic matter and its labile forms in the sediments originating from Ustka. Strong anthropogenic pressure found at the beach in Ustka also contributes to higher concentration of uncharacterized fraction of organic carbon in the area. Analyzing alimentary usefulness of the organic matter there, it seems to be higher at the beach in Czołpino.
    Pobrano i zanalizowano osady plażowe pochodzące z dwóch plaż polskiego wybrzeża Morza Bałtyckiego. Osady pobierano w dwóch porach roku – zimą i latem – na dwóch stanowiskach w zależności od wpływu wody morskiej na badane osady. Na każdym stanowisk pobierano osady powierzchniowe (0–5 cm) oraz osady z głębokości 10–15 cm. Z przeprowadzonych badań wynika, że skład chemiczny osadów plażowych, a także ich jakość jako pokarmu dla bytującego tam psammonu ma związek z antropopresją, głębokością, z jakiej pobierano osady oraz bezpośrednim wpływem wody morskiej na te osady. Wykonane analizy pokazują, że w osadach pochodzących z Ustki występuje znacznie więcej materii organicznej oraz jej labilnych form. Silna presja antropogeniczna występująca na plaży w Ustce jest również przyczyną znacznie większego stężenia niescharakteryzowanej frakcji węgla organicz nego na tym terenie. Analizując przydatność pokarmową znajdującej się na obu plażach materii, można zauważyć, że jest ona znacznie większa w Czołpinie.

    Opis:
    This study focused on verifying the fluctuating asymmetry hypothesis in the crustacean Talitrus saltator, which lives in sandy beaches. We analysed three populations, one from an unpolluted Tuscan beach relatively free of tourism, and two from Sicilian beaches, which have been increasingly used for tourism and have been exposed to hydrocarbon/pesticide pollution. Results confirmed the sexual dimorphism in the second antennae flagella, which in the Tuscan population presented directional asymmetry. This population had a significant level of fluctuating asymmetry in the P6 and P3 meri. The results showed the importance of the developmental stage during which environmental mechanical stresses act.

    Opis:
    The research area is located on the coast of the Baltic Sea, along the Gulf of Gdańsk. It includes a beach where sand replenishment was carried out in 2019. The aim of the study was to investigate the morphodynamics of beach deposits in replenishing and non-replenishing areas during one year. No environmental dynamic conditions sufficient to alter significantly the beach morphology and sediment characteristics occurred during the study period, November 2019 to August 2020. One storm event was recorded, but did not significantly affect the beachform. The transverse beach profiles, which were artificially recharged in June 2019, were lowered by 0.6 to 1.2 m. The greatest changes were caused by the erosive activity of the waters of the Jelitkowski Stream.

    Opis:
    On nine beaches and two transects in the surf zone along the Dutch coast the presence of benthic macrofauna was studied in relation to basic abiotic characteristics. According to Short’s classification system, Dutch beaches are mesotidal and dissipative (Ω = 8.6), and the RTR is low (1.52–1.27), which means that they are not tide-dominated. BSI ranged from 1.4 to 1.1 for the northern and western Dutch coasts respectively and had an overall value of 1.2. The rates of exposure of the beaches varied between 8 and 12, and are therefore regarded as sheltered to moderately exposed. The Dutch beaches display a geographical trend in beach types. Those of the Wadden Sea islands in the northern part of the Netherlands are dissipative, flat, fine-grained, and host high densities of many species of benthic macrofauna. The beaches along the western Dutch coast are less dissipative, steeper, with a higher mean grain size; the species diversity and abundance there are lower. Species diversity and abundance on the beaches increase from the high- to the low-water line. The maximum number of species was found between 0 and –1 m relative to the mean tidal level. The abundance peaks just above the mean tidal level, while the biomass reaches a maximum at the mean tidal level. Species diversity and abundance are low in the surf zone, but increase towards deeper water. Species numbers are high and the abundance is very high in the trough between the two bars. The relation between the diversity and abundance of macrobenthic species on the one hand, and the sediment composition, water column depth, and position between the bars on the other show a clear pattern of zonation for the beach, surf zone and near-shore: (1) a supralittoral zone with insects and air-breathing crustaceans, (2) a midshore zone, with intertidal species, (3) a lower shore zone, whose species extend into the shallow surf zone, and (4) a zone of sublittoral fauna in the trough between the two breaker bars within the surf zone.

    Trophic models of the micro and meiobenthic community of six sandy beaches on the Ligurian coast (north-western Mediterranean Sea) have been performed to assess variations in structure and function of the ecosystem. A novel approach based on the determination of the feeding predisposition of the benthic community revealed that there is a significant shift in the trophodynamics of the system with respect to environmental constraints. Along an emerged-submerged gradient the benthic community displayed a clear trend from a fundamentally detritusdependent structure to an autotrophic, more balanced and diversified one. The trends analysed focus on the importance of the swash zone as a transitional area between the land and the sea that is characterised by a high diversity and activity of the trophic network.

    The purpose of this study is to determine and analyze the level of diversity of Chlorophyta on the intertidal area of Karapyak waters. The study was conducted from January to March 2018 at Karapyak beach, Pangandaran regency. Research parameters analyzed were species density, species frequency, species cover, Importance Value Index, Diversity and Uniformity of macroalgae. The measured environmental parameters are temperature, salinity, DO, pH, nitrate and phosphate. The results showed that there were 6 species macroalgae of the division Chlorophyta found on Karapyak Beach. The macroalgae (H) diversity index value is in the low category based on the index of the Shannon-Wienner. Meanwhile, the uniformity index value (E) is in the high category according to the Evennes index, which means that no species dominates the Karapyak waters.

    This research was to assest of marine debris in Pangandaran beach. Marine debris sampled from 2016 and 2017 around west Pangandaran using Ocean Conservancy (OC) form to find information about distribution, abundance, and types. The result is debris on the West coast of Pangandaran is originally comes from settlements, tourists, traders, and fishermen. The highest accumulation of marine debris happened in October with total weight 44.385 kilos, while the lowest accumulation happened in May with total weight 38 kilos. this is due to Citumang River had overflowed due to heavy rain and then was swept away along the coastline and piled up an area near the bay in October. In May and August the debris which most find is cigarette with the percentage 28% in May and 35% in August. While in October the debris which most find is a plastic bag with percentage 33%. From six types of debris, the dominant debris per types as follows: Most likely to find items is cigarette butts, Fishing gear is rope, Packaging material is other plastic/foam packaging, Personal hygiene is diapers, Other trash is cigarettes lighters, and Tiny trash less than 2.5 cm is foam pieces. The specific debris at Pangandaran beach is the fisheries tools like a rope and net, the rope embedded in the ground and make it hard to take out. One of the factor the large number of debris in Pangandaran is tourism activity and fisheries activity. In addition, the study indicates that there is a strong relationship between human activities and spreading of debris.

    Opis:
    Transformation of waves on sandy beaches, their breaking, set-up and run-up are the main factors contributing to fluctuations in the water table and groundwater flow. In this paper, the run-up mechanisms have been studied using analytical models. In contrast to the standard models, the waves approaching the shoreline are assumed to be dispersive and the equivalence of the non-linear and linear solutions for the extreme characteristics of wave run-up, such as the height of maximum run-up and the velocity of run-up, are used. A linear system of equations for the run-up of breaking waves is developed. This system is based on the application of the mild-slope equation in the deeper area, where waves are dispersive, while the linear equations of shallow water are applied close to the shoreline, where the water depth is a linear function of distance. The dissipation factor in the shallow water equation has been formulated using its resemblance to the mild-slope equation for a non-permeable sea bottom. Application of the method is illustrated for various bottom profiles and wave characteristics, and theoretical results compared well with experimental data. These solutions of the run-up phenomena will assist future studies on wave-induced beach groundwater flow.

    Opis:
    A coastal aquifer has a dynamic seaward boundary at the beach face where physical and ecological processes are influenced by oceanic water level fluctuations. Many basic groundwater concepts and the role of the impact of groundwater seepage on beach ecosystems are still poorly understood. Studies are needed to improve our understanding of the relationships between surface and subsurface flow processes on beaches. This is particularly helpful in clarifying the interaction of the physical processes, biodiversity and productivity of sandy beaches, sediment transport and coastal structure stability and modern beach nourishment techniques. As the estimation of infiltration into beach sand is very difficult to carry out under real sea conditions, a control led large-scale laboratory experiment was carried out in the LargeWave Channel in Hannover (Germany) as part of a project supported by the European Community (contract HPRI-CT-2001-00157). First part of the paper describes the technology applied in the experiment and reports some preliminary results.

    The results of the present study showed variability in resistance of FC bacteria isolated from beach sand and sea water against tested antibiotics. Enteric bacteria were the most resistant to clindamycin and penicillin while the most sensitive to ciprofloxacin, gentamycin, neomycin, rifampicin and streptomycin. Fecal coliform bacteria inhabiting sand were more resistant to nearly all tested antibiotics compared to bacteria isolated from sea water. The majority of bacteria inhabiting sea water and sand of the studied beach were resistant to only 1-4 antibiotics out of the 12 antibiotics tested. Fecal coliform bacteria isolated from Ustka beach were the most resistant to β-lactam and lincosamide antibiotics, while the most susceptible to aminoglycosides.
    Badano oporność na antybiotyki bakterii fekalnych wyizolowanych z wody morskiej i piasku rekreacyjnej plaży znajdującej się na południowym wybrzeżu Morza Bałtyckiego. Uzyskane wyniki badań wykazały zmienność w oporności bakterii z grupy coli wyizolowanych z piasku i wody morskiej wobec badanych antybiotyków. Mikroorganizmy te były najbardziej odporne na penicylinę i klindamycynę, a najbardziej wrażliwe na ciprofloksacynę, gentamycynę, neomycynę, ryfampicyny i streptomycyny. Bakterie kałowe z grupy coli zasiedlające piasek były bardziej odporne na prawie wszystkie badane antybiotyki niż te izolowane z wody morskiej. Większość bakterii zasiedlających wodę morską i piasek badanej plaży była odporna na zaledwie 1-4 antybiotyków z 12 badanych. Bakterie kałowe z grupy coli izolowane na plaży w Ustce były najbardziej oporne na antybiotyki beta-laktamowe oraz linkozamidy, a najbardziej podatne na aminoglikozydy.

    Opis:
    Artificial beaches, i.e. places in the public sphere, are usually intended for recreation, located at water reservoirs, rivers, and their surface is naturally occurring or applied sand. The urban bathing beach located in Szczecin by the Deep lake has sand purchased and distributed on the beach by the Municipal Services Office in Szczecin (a few hundred ton). The beach is divided into sectors, a volleyball court is in one part, in the next section catering and sanitary facilities are located, and the remaining area is a place intended for sunbathing and playing games. The aim of the experiment was to assess the effects of different ways of using the beach on changes of microbiological properties of the sand. The tests were taken from the beach sand in May 2013 (first term examinations), and in September, after several months of use (the second term of examinations). The sand was collected near catering and sanitary sector (the first object) and from the area of the volleyball court (the second object), as well as the playground for children (the third object). The facilities were distanced from the shoreline of the lake by approx. 8 metres. The comparison included the number of heterotrophic bacteria, fungi and the detected presence of coliform bacteria, including Escherichia coli, bacteria of the genus Salmonella and eggs of intestinal parasites. In any of the objects, or the periods of time, eggs of intestinal parasites and bacteria of the genus Salmonella were detected. The presence of coliform bacteria including E. coli was found in the sand collected from a catering-sanitary zone, there was also the biggest number of bacteria and fungi. The number of heterotrophic bacteria and fungi was similar in samples of sand taken from the volleyball court and from the playground, in this sand there was no bacteria belonging to the E. coli species, although in several samples from the playground other bacteria belonging to the coliform genus were detected. To sum up, it is possible to state that the same sand used in various ways is gaining different microbiological characteristics. The values of the studied parameters differed significantly with regards to sand taken from the area of consumption, hygiene-sanitary activities and sand collected from the area of active leisure (the court and playground). These results indicate the need for a deliberate selection of location for sunbathing (children playing in the sand) away from the sites for culinary and sanitary purposes.

    Opis:
    Airlie beach houses are quite common in the coastal areas of Australia. These houses, similar to other buildings, provide comfort for their residents. House comfort is not limited to temperature or sound pollution, vibration can be considered as another equally important factor. In this article, the vibration of an Airlie beach house was investigated. The base steel structure was modeled in SolidWorks and Space Gass for evaluating stress distribution and nodal displacement, respectively. To find the root cause of the distressing vibration of the house, which was felt with dwellings, the axial acceleration of the house’s structure was determined. Some feasible solutions such as adding a fiber-reinforced polymer joist hanger, inserting additional rubber padding to the joist hanger, and attaching additional bracing, were discussed and a cost analysis was considered for the solutions. Eventually, the nature of the best solution, which was adding rubber, was tested experimentally.

    Opis:
    Two contrasting coastal profile models are applied to three bathymetries including a uniform gradient beach and natural profiles (multi-barred and multi-stepped) obtained from Lubiatowo, Poland and La Barrosa, Spain. The first model, developed at the Institute of Hydro-Engineering of the Polish Academy of Science (IBW PAN) (Poland), couples a quasi-3D model for nearshore hydrodynamics with a quasi-phase resolving sediment transport model which considers transport in the bed load, contact load and outer layers. The second model (PLYMPROF), developed at the University of Plymouth (UK), couples a relatively simple wave transformation model with a new abstracted description of cross-shore sediment transport beneath waves. A variety of model simulations are described, including simple runs with uniform wave forcing (up to 50 days in duration using PLYMPROF) and runs with parameterized wave forcing (wave height and wave period in deep water) for periods with one or two storm events (6-11 days total duration). Both models coped well with the different initial profiles and with uniform and time-varying wave conditions. The results of the simulations suggest that onshore-directed sediment transport in the shoaling and outer surf zones is dominant for the cases considered. Compared to the IBW PAN model, the PLYMPROF model results (using coefficients from a separate study of bar evolution at Duck, USA) show larger offshore-directed transport in the inner surf zone associated with return flow, with the overall sediment transport pattern located considerably closer to the shore. Alteration of a single coefficient in the PLYMPROF model shifts the predicted transport pattern seawards, but also results in enhanced offshore-directed transport. Despite differences in predicted cross-shore sediment transport the two models produced surprisingly similar trends in overall profile evolution suggesting that feedback between existing bathymetry and the sediment transport pattern may exert a major control on profile development. Results also suggested that bar migration patterns cannot be simply related to the occurrence or absence of storm conditions, but rather depend more subtly on the exact placement of wave breaking locations in relation to existing bars. Incorporation of tidal water level variations for La Barrosa produced small changes in model predictions, with tidal migration of the sediment flux pattern suppressing the development of bar morphology in line with the form of the observed profile.

    Opis:
    Determining the level of solid pollution in beach sands located near artificial inland water bodies in order to maintain high safety standards is a difficult and expensive task. The tests aimed at determining beach pollution caused by solid wastes through analysis of toxic and chemical concentrations, are time-consuming and usually require several days before the results are available. In addition, the maintenance of the beach area involving beach raking or grooming, and the seasonal replenishment of sand makes it difficult to realistically determine the chemical or bacterial contamination of the tested material. Solid pollutants, such as glass, caps, cans, thick foil, metal, and plastic fragments, pose a greater health risk to beachgoers. The above-mentioned pollutants, especially small ones, are hardly visible on the surface or they are buried at shallow depths. Beach garbage poses a serious threat that can lead to infections from cuts and scratches. These injuries can become infected, further jeopardizing the health and lives of beachgoers due to risks like tetanus, staphylococcus, etc. The authors presented a new petrographic method aimed at assessing the quality of sand by examining the content of solid pollutants. The obtained results allowed us to conclude that the mentioned procedure can be used for a quick quantitative estimation of the content of potentially dangerous and undesirable pollutants in beach sands. Consequently, the method implemented to determent the amount of solid pollutants in beach sands has proven to be a valuable tool for recreational facility administrators, helping them in taking necessary measures to ensure the safety of beach users. Petrographic analysis of beach sands revealed the presence of pollutants of plant origin (0.4–1.8%), plastic (0.1–0.4%), paper (0.1–0.6%), charcoal (0.1–0.5%), glass (0.1–0.4%), metals (0.1–0.4%), rust (0.1–0.3%), ash and slag (0.1–0.3%), and fossil coals (0.1–0.2%).

    Opis:
    Hairtail fish (Trichiurus lepturus Linnaeus, 1758) are a major commodity of high economic value in Pangadaran. This study aims to determine the most selective fishing gear for hairtail fish commodities based on the frequency of hairtail fish length, the proportion of the main catch and by-catch in Pangandaran District. Data collected are primary and secondary data. Primary data consists of catch data and fish size length. The catch is obtained by collecting the results of landing fish with gill nets and beach seines. Fish size length data obtained through direct measurement when the fish is landed. Secondary data collected is data on capture fisheries production in Pangandaran District. Data analysis consisted of calculation of length size distribution and comparison of main and by-catches with fishing gears. The analysis was carried out with the help of Microsoft Excel software. The results of this study indicate that hairtail fish in Pangandaran District were captured using gill nets and beach seines. Based on the results of the research conducted on August 2018 until January 2019, it can be concluded that gill net fishing gears are more selective compared to beach seines based on several parameters observed, namely the length distribution and the proportion of main catch : by-catch. The results showed that the comparison of the length distribution of hairtail fish that was appropriately caught between gill nets and beach seines was 85.74% : 30,74%. Comparison of the proportion of main catch : by-catch between gill nets and beach seines was 52.38%: 23.57%.

    Opis:
    We checked the spatial pattern of debris stranding at Praia de Santos (Brazil) in the first hour after the peak of high and low tide in summer and winter. We recorded and counted 20 types of debris (natural and anthropogenic) in 6 transects arranged in 3 zones along the beach (deposition, transport, and erosion). Canonical Correspondence Analysis (CCA) showed that buoyancy was an essential property in distinguishing debris stranding behaviours. The erosion zone, closer to the estuary showed that many mollusk shells, ropes and rocks, while plastics, styrofoam and fiber nylon were in the deposition zone. Throughout the estuary, we inspected the beach, identifying sections of origin and accumulation associated with the circulation system and currents. We propose the removal and recycling of debris from accumulation sites near highways and urban systems.

    Opis:
    Shallow water equations formulated in material variables are presented in this paper. In the model considered, a three-dimensional physical problem is substituted by a two-dimensional one describing a transformation of long waves in water of variable depth. The latter is obtained by means of the assumption that a vertical column of water particles remains vertical during the entire motion of the fluid. Under the assumption of small, continuous variation of the water depth, the equations for gravity waves are derived through Hamilton's principle formulated in terms of the material coordinates. This formulation ensures the conservation of mechanical energy. The approximation depends on the wave parameters as well as on the bed bathymetry. The latter may influence a solution of the model decisively; thus, one should be careful in applying the description to complicated geometries of fluid domains encountered in engineering practice.

    The article presents a dermatosis that occurs in tropical and subtropical countries. Though the definitive hosts of the cutaneous larva migrans parasite are animals, humans can become accidental hosts and they are infected when their skin comes into contact with damp soil, most frequently sand. The disease is only present in the epidermis where an itch is brought about by the mining activity of the larva. Sunbathers and divers who put on their gear on a beach, on account of the epidermis maceration caused by a prolonged exposure to water, are particularly susceptible to the penetrative activities of the larva. In Poland the cutaneous larva migrans is in most cases mistaken for nettle rash or eczema.

    The paper presents recent investigations of beach run-up phenomena at the Coastal Research Station of the Institute of Hydro-Engineering of the Polish Academy of Sciences at Lubiatowo, Poland. The local beach is typical of open-sea coasts of the south Baltic Sea, featuring multiple longshore bars that form predominantly dissipative systems. Measurements were taken to verify the existing formulas for the run-up height, bearing in mind that they had been derived for entirely different, oceanic conditions. The results indicate that these formulations can be adapted to south Baltic Sea conditions. This however, will require significantly larger data sets, which we intend to obtain in the near future.

    Opis:
    Beach wrack is a unique issue. It is both an ecological problem for the eutrophicated reservoirs such as the Baltic Sea and the social one associated with nuisance for inhabitants and tourists visiting seaside resorts. This generates a problem for the institutions responsible for beach management (local authorities). Nowadays local authorities generally leave cleaning the beach to local companies and it is not known how the beach wrack material is utilized. According to the current trend, the nuisance of beach wrack should be turned into a resource that will bring benefits. In order to understand what beach wrack really is, it is necessary to establish a specific definition. The material washed out by the sea contains not only the natural substances of organic origin, but also human products: plastics, glass or metals, which in many cases forces to pre-select before using the technology. Good treatment of material the quantities of which are undefined and the occurrence is variable, constitutes a real challenge. The beach wrack processing on reed bed system, so far used mainly for the treatment of sewage sludge, seems to be a good idea. It is an innovative technology that is expected to have similar results as for the processing of sewage sludge from wastewater treatment, i.e. a high nutrient fertilizer. In accordance with European Union recommendations, the possible use of beach wrack as a fertilizer in agriculture or enrichment of compost, will close the circulation of organic matter in environment, thus entering the reed bed system into a circular economy. Many aspects related to the reed bed system favor the use of this technology in the practical processing of marine organic waste.

    Opis:
    This paper evaluates the second part of a three-year field study to investigate the effects of the beach macro- and meiofauna community structure on the decay of stranded wrack on Hel Beach (see Jędrzejczak 2002),f ocusing on successional changes and the colonisation of wrack by beach fauna. The investigation enabled the associated faunal assemblages to be characterised. Zostera marina tissue was colonised by the supralittoral fauna in two distinct phases. The macrofauna, including the talitrid amphipod Talitrus saltator,ad ult Diptera and Coleoptera, colonised the wrack within a day,with maximum numbers being recorded after 3 days. Thereafter,their numbers in the samples declined and the meiofauna, consisting of nematodes, oligochaetes,tur bellarians and dipteran larvae, became increasingly abundant. After 18 days,the wrack surface was dominated by meiofauna. This faunal succession was not directly related to the degradation of the seagrass tissue,whic h proceeded linearly throughout the study period. Exclusion of macrofauna from the wrack by the use of < 1 mm mesh litterbags had no appreciable effect on the rate of dry matter loss. Therefore,the major macrofaunal wrack consumers,including T. saltator and Coleoptera,d id not affect the rate of seagrass disintegration. The effect of meiofaunal nematodes, oligochaetes,gast rotrichs and turbellarians on wrack breakdown could not be accurately determined. However,the development of the meiofaunal community suggested that changes in the fauna community were linked more closely to successional changes in the chemistry and/or microflora of the beach wrack than to its physical breakdown.

    Opis:
    Hawksbill sea turtles are scattered in Indonesia, especially on small uninhabited islands and are the only species of turtle most bound to tropical waters. The hawksbill has experienced a drastic decline in population mainly due to bycatch in fishing activities and disturbance of the nesting habitats due to anthropogenic presence. Kepayang Island in Belitung is one of the areas used as hawksbill as a habitat for nesting to laying eggs. To get information about hawksbill on this island, a study was conducted to find out the characteristics of hawksbill nesting beaches on Kepayang Island, Belitung. The survey was carried out in July 2014 and successfully identified 12 nests as an observation sample. Observations show that the coast of Kepayang Island where nesting turtles have a narrow beach width of less than 20 m with a slope of between 10° to 16° and an average intertidal area as wide as 11.5 meters. The texture of sand in the nest is coarse to fine sand which is dominated by fine and medium sand and has a temperature of around 27.7 °C to 30.2 °C measured at the bottom of the nest. The range of sand pH distribution on Kepayang Island is between 6 to 8 with a moisture content of 3.1 to 6.6%. The coastal vegetation formation in Kepayang Island is dominated by Barringtonia and Pescaprae with vegetation in the form of screwpine (Pandanus tectorius), railroad vine (Ipomoea pescaprae) and Barringtonia (Barringtonia asiatica). However, there are predators of turtle eggs and hatchlings, especially water monitor lizards (Varanus salvator), sea birds e.g. brahminy kite (Haliastur indus) and gulls (Chlidonias leucopterus). In general, Kepayang Island has characteristics suitable for hawksbill nesting sites.

    Opis:
    The aim of this work was to explore the possibilities of utilising the macroalgae accumulating on the Sopot beach, a part of the Gulf of Gdańsk (Baltic Sea). During this work (2004–2006) a range of activities were undertaken: monitoring the occurrence of macroalgae, collection of plant material, taxonomic identification, laboratory analyses of contamination (metals – Cd, Pb, Ni, Zn, Cu, Cr, Hg; radionuclides – 137Cs, 40K; organic contaminants – polychlorinated biphenyls, polycyclic aromatic hydrocarbons), the stage of algal degradation and studying possible uses of the plant material collected on the beach. The most suitable way of utilising the plant material seems to be as a biofertiliser. Laboratory growth tests were carried out to assess this possible use; they were successful.

    Opis:
    The microphytobenthic primary production and chlorophyll a content were studied over the annual cycle (May 1998 – May 1999) on a non-tidal Baltic sandy beach at three stations along the beach gradient: littoral, waterline and splash zone. The chlorophyll a concentrations varied between 0.88 and 12.18 μg cm−3. Net and gross primary production rates respectively lay within the ranges 0.1–31.4 mgC m−2 h−1 and 0.2–41.8 mgC m−2 h−1. The highest values of both Chl a content and primary production were noted at the littoral station, the lowest ones at the waterline. The mean annual P/B ratio was highest at the waterline. The differences in Chl a content between stations were statistically significant and may be related to water dynamics, resuspension and water content. Production rates were highly variable on monthly time scales, and the highest results at all the study locations were noted in July. The gross photosynthetic rates were significantly correlated with water temperature.

    Opis:
    The occurrence of algae on the Sopot beach was investigated from 2004 to 2006 from the beach management point of view. Various methods were applied in an attempt to understand the mechanisms underlying the accumulation of algae on the shoreline. They included daily observations of the occurrence of macrophyta on the beach, absorption measurements of acetone extracts of the particulate matter in the seawater, the collection of macrophyta and phytoplankton samples for biomass and taxonomic identification, and determination of the degree of decomposition on the basis of chloropigment analyses. The results were related to the environmental conditions: meteorological data and the physicochemical parameters of the seawater. The biomass recorded on the beach consisted mainly of macroalgae and a small proportion of sea grass (Zostera marina). The phytoplankton biomass consisted mainly of dinoflagellates, diatoms, cyanobacteria, euglenoids and cryptophytes. The conclusions to be drawn from this work are that the occurrence of huge amounts of macrophyta amassing on the Sopot beach depends on the combined effect of high solar radiation in spring and summer, high-strength (velocity × frequency) south-westerly winds in May-September, followed by northerly winds, bringing the macrophyta from Puck Bay on to the Sopot beach. At the same time, their abundance along the beach varies according to the shape and height of the shore, the wind strength and the local wind-driven seawater currents. According to estimates, from 2.2–4.4 × 102 tons (dry weight) of macrophyta can be moved on to the Sopot beach in one hour. In October, strong southeasterly winds can also transport huge amounts of decomposing biomass onshore. The phytoplankton content in the total biomass is negligible, even though at low concentrations its biological activity may be considerable. The intensive phytoplankton blooms observed on the Sopot beach in summer are not always caused by cyanobacteria.

    Opis:
    The investigations of the chemical composition of sands were conducted on the beach in Ustka and Czołpino. The Ustka is a typical tourist town and Czołpino is located in the Slovinski National Park away from urban or rural areas. The beach sediments in Ustka contain much more organic matter, nitrogen and phosphorus compounds as well as calcium carbonate than analogous deposits in Czołpino. The effect of sea water was manifested in the high content of organic matter in places having permanent contact with sea water. The content of the organic matter increased together with with the depth of settlings in these places. However more organic matter in surface layers was observed in regions more distant from the sea, because penetration of organic matter into the sediments is possible during precipitation. The concentration of ammonia nitrogen in the analyzed beach deposits increased with depth, what probably results from the lower oxygen content in deeper layers. It was confirmed that organic matter in sands of the beach in Czołpino is of natural origin, while in Ustka it is primarily of anthropogenic origin.
    Celem pracy było oszacowanie wpływu czynników antropogenicznych na skład chemiczny piasków z plaż w Ustce i Czołpinie. Ustka jest typową miejscowością uzdrowiskową i turystyczną, natomiast Czołpino leży na terenie Słowińskiego Parku Narodowego, z dala od miast i wiosek. Osady plażowe w Ustce zawierały znacznie więcej materii organicznej, związków azotowych i fosforowych oraz węglanu wapnia niż analogiczne osady w Czołpinie. Wpływ wody morskiej na obydwu plażach odzwierciedlał się dużą zawartością materii organicznej w miejscach mających ciągły kontakt z woda morską. Koncentracja tego składnika wzrastała tam wraz z głębokością. W rejonach plaży bardziej oddalonych od morza proces przenikania materii organicznej w głąb osadów jest natomiast możliwy przede wszystkim podczas opadów atmosferycznych, dlatego głębsze warstwy były uboższe w ten składnik. Prawdopodobnie ze względu na mniejszą zawartość tlenu w głębszych warstwach piasku koncentracja azotu amonowego w badanych osadach plażowych wzrastała wraz z głębokością. Stwierdzono, że materia organiczna zawarta w piaskach plaży w Czołpinie jest pochodzenia naturalnego, a w Ustce głownie pochodzenia antropogenicznego.

    Opis:
    Utilization of various amino acids and carbohydrates by heterotrophic bacteria isolated from a sandy beach in Sopot, Poland, southern Baltic Sea coast, was determined. The most intensive growth of bacteria was observed in the presence of amino acids, while carbohydrates were utilized less actively. Differences in the utilization of individual amino acids and carbohydrates by bacteria have been determined. The highest capability to assimilate amino acids and carbohydrates was observed in bacterial strains isolated from the middle part of the studied beach. No major differences were determined in the intensity of assimilation of the tested compounds by bacteria isolated from the surface and subsurface sand layers. Bacterial utilization of amino acids and carbohydrates depended on the chemical structure of those compounds.
    W pracy przedstawiono wyniki badań dotyczących wykorzystania w procesach metabolicznych aminokwasów i cukrów przez bakterie heterotroficzne wyizolowane z plaży morskiej południowego Bałtyku. Stwierdzono, że bakterie wykazywały znacznie lepszy wzrost w obecności aminokwasów niż cukrów. Najbardziej preferowanymi przez bakterie aminokwasami były kwas asparaginowy i histydyna, a cukrami mannoza i ryboza. Nie stwierdzono różnic w intensywności asymilacji aminokwasów i cukrów przez bakterie wyizolowane z powierzchniowych i podpowierzchniowych warstw piasku. Natomiast wykazano, że poziom przyswajania przez bakterie obu badanych grup organicznych związków niskocząsteczkowych zmieniał się istotnie w płaszczyźnie horyzontalnej plaży morskiej. Szczepy bakterii wyizolowane ze środkowej części plaży charakteryzowały się największa aktywnością metaboliczna wobec testowanych aminokwasów i cukrów. Poziom bakteryjnego wykorzystania aminokwasów i cukrów zależał od ich budowy chemicznej. Najwyższy procent testowanych szczepów bakterii preferował aminokwasy aromatyczne i siarkowe, a spośród cukrów heksozy.

    Opis:
    A brief investigation of light minerals along the beaches between Valinokkam and Tuticorin has been carried out for the first time along the Southern Tamilnadu coast in order to discover the provenance of the sediments. The study spotlights a wide variation in light mineralogy along the three zones of the investigated area (Valinokkam, Vaippar and Tuticorin). A higher percentage of quartz is reported from the Valinokkam (48.34 to 68.63%) and Tuticorin zones (55.66 to 73.05%) than from the Vaippar zone (40.24 to 60.77%). The trend with regard to the maturity index is similar, with appreciably higher values in Valinokkam (1.15 to 1.89) and Tuticorin (1.61 to 1.94) than Vaippar (0.79 to 1.39). Morphological analysis of quartz grains shows a higher order of sphericity and roundness values in Valinokkam and Tuticorin as compared to Vaippar. Moreover, the surface texture of quartz grains observed with the aid of scanning electron microscope (SEM) photographs reveals the presence of different depositional environments and the multiple origin of beach sediments in the study area. From the present study of the light mineralogy of beach sediments, it is inferred that the source of the sediments is a mixed type: igneous and metamorphic crystalline rocks, together with palaeosediments.

    Opis:
    The marine species richness (MSR) recorded in 159 sandy beach surveys was analysed in relation to beach width (W). MSR is the number of macrobenthic species collected in a standard intertidal transect survey, excluding insects. Beach width (W) was estimated by dividing the spring tide range [m] by the beach face slope, to give a value in [m]. The relationship between MSR and W was best described by a semilog (exponential) model, which was highly significant: MSR = −5.2+ 10.8 logW. The fit of a power model (MSR = cWz) was also significant. The steep slope of the curve for a power model (z = 0.49) suggests that beaches function as isolated rather than contiguous habitats and that the nature of the habitat becomes more benign as beaches widen. There are some latitudinal effects, with tropical beaches displaying a higher species-area relationship for any beach width than other regions.

    Opis:
    The sediments of the beaches along the central coast of Tamil Nadu from Pondicherry to Vedaranyam were studied for their textural variation. 108 sediment samples collected from the low-, mid-, and high-tidal zones, as well as the berms and dunes of different beach morpho-units were analysed. The study area was divided into three sectors (northern, central and southern) on the basis of prevailing energy conditions and oceanographic parameters. The poorly sorted, negatively skewed, coarser sediments of the northern sector are indicative of denudational processes taking place there. Medium-to-fine, moderately-to-well sorted, positivesymmetrically skewed sediments dominate the central sector, probably as a result of the influence of palaeo-sediments deposited by rivers from inland as well as by waves and currents from offshore. Fine, poorly sorted, positive-symmetrically skewed sediments dominate the southern sector, highlighting depositional processes. Linear Discriminant Function Analysis (LDF) of the samples indicates a shallow marine environment origin for all the three sectors. These results show that reworked sediments, submerged during the Holocene marine transgression, are being deposited on present-day beaches by waves, currents and rivers in the study area.

    Opis:
    Sandy beaches are highly exploited but very dynamic and fragile environments. Driven by waves, the water flow through the beach body is able to transport oxygen, and hence help to maintain biological activity in the porous media. The paper presents a theoretical attempt to predict the groundwater circulation due to wave set-up. Two systems of circulations have been discovered, related to two different gradients of the set-up height. For the offshore gradient, the horizontal excess pressure gradient induces flow in the offshore direction. However, closer to the shore, the pressure gradient is reversed and the resulting flow moves shorewards.

    Opis:
    The objective of the present study was to evaluate heterotrophic bacteria capable of growth in the presence of different antibiotics and their mixture in such dynamic ecosystem as marine beach. Mixture antibiotics had the strongest inhibitory effect on the growth of bacteria inhabiting sand of studied beach. Culturable bacteria were more resistant to ampicillin than to novobiocin and tetracycline. Inhibitory influence antibiotics on growth bacteria inhabiting studied beach were in the following order: mixture antibiotics > novobiocin > tetracycline > ampicillin.
    W pracy przedstawiono wyniki badań dotyczących określenia hamującego wpływu rożnych antybiotyków i ich mieszaniny na wzrost heterotroficznych bakterii zasiedlających piasek plaży morskiej zlokalizowanej na terenie Słowińskiego Parku Narodowego w rejonie Czołpina. Proby piasku na tej plaży pobierano w profilu horyzontalnym z czterech stanowisk (morze, strefa brzegowa, środkowa część plaży, wydma), a w profilu wertykalnym na każdym stanowisku z dwóch (0-5 cm, 10-15 cm) głębokości. Badania te wykazały, że mieszanina antybiotyków w podłożu hodowlanym wywierała bardziej hamujący wpływ na wzrost bakterii zasiedlających badaną plażę niż pojedyncze antybiotyki. Wśród testowanych antybiotyków neomycyna i tetracyklina wykazywały znacznie większy niż ampicylina hamujący wpływ na wzrost bakterii. Wykazano, że hamujący wpływ antybiotyków i ich mieszaniny na wzrost bakterii zasiedlających powierzchniowe i podpowierzchniowe warstwy piasku był podobny. Stwierdzono, że testowane antybiotyki i ich mieszanina miały wpływ na wzrost chromogennych i achromogennych bakterii zasiedlających piasek badanej plaży morskiej.

    Opis:
    The communication process in the maritime water rescue system is one of the key factors affecting the final effect of the rescue operation. Emergency services encounter not only new threats, but also communication problems. Communication between individual rescuers and teams usually proceeds correctly and efficiently. The specific nature of their job bring some problems, which are most often caused by a high psychological burden and people from outside the rescue teams, which hinder the correct course of the rescue operation. The way in which the actions of water rescuers are carried out and what their effect is, depends to a large extent on the effective contact between individual rescuers and teams.
    Proces komunikacji w systemie morskiego ratownictwa wodnego jest jednym z kluczowych czynników wpływających na końcowy efekt akcji ratowniczej. Służby ratownicze spotykają się nie tylko z nowymi zagrożeniami, ale również z problemami komunikacyjnymi. Komunikacja między poszczególnymi ratownikami oraz zespołami zazwyczaj przebiega prawidłowo i sprawnie. Specyficzny charakter pracy sprawia, że występują pewne problemy, które najczęściej są spowodowane dużym obciążeniem psychicznym oraz osobami spoza zespołów ratowniczych, które utrudniają poprawny przebieg akcji ratowniczej. To w jaki sposób będą prowadzone działania ratowników wodnych oraz jaki będzie ich efekt zależy w bardzo dużym stopniu od sprawnego kontaktu między poszczególnymi ratownikami i zespołami.

    Opis:
    The article is an attempt to settle a matter of what art demands from the artist and whether the artist has a right to sacrifice others for the sake of their work. It discusses the escapist attitude to life of the artists who are characters of Ian McEwan’s three novels. Amsterdam, On Chesil Beach and, to a lesser extent, Atonement present this particular art-artist relation. The article also demonstrates McEwan’s accomplished use of auditory images as well as musicology terms as character and atmosphere-building elements which make the narration harmonise with the narrative.
    Artykuł jest próbą ustalenia, czego sztuka wymaga od artysty oraz czy artysta ma prawo poświęcić innych dla dobra swojego dzieła. Autorka rozważa w nim eskapistyczny stosunek do życia artystów – bohaterów trzech powieści Iana McEwana. Amsterdam, Na Plaży Chesil oraz, w mniejszym stopniu, Pokuta prezentują tę szczególną relację sztuka – artysta. W artykule ukazano także mistrzowskie posługiwanie się McEwana obrazami dźwiękowymi, jak również terminologią z zakresu muzykologii, jako elementami budującymi postaci i tworzącymi atmosferę, co sprawia, że narracja harmonizuje z fabułą powieści.

    Opis:
    W artykule przedstawiono rezultaty badań na temat przestrzeni beach barów we Wrocławiu, poddanych obserwacji w 2018 r. Ich celem była ewaluacja przestrzeni tych miejsc ze szczególnym nastawieniem na ich działanie (program + funkcja). W badaniach postanowiono zestawić beach bary z oficjalnymi przestrzeniami publicznymi miasta. Celem głównym tego zestawienia było pokazanie najistotniejszych podobieństw i różnic między tymi przestrzeniami, a tym samym zbadanie słabych i mocnych stron przestrzeni miejskich, co mogłoby być pomocne w ich wzbogacaniu i rozwijaniu. Szczególnym zainteresowaniem objęto wszystkie te elementy programu i funkcji, które mogłyby wzmocnić społeczną interakcję – życie w tych przestrzeniach. Celem pośrednim była odpowiedź na wywołane w tytule pytanie, jakie znaczenie dla działania przestrzeni we współczesnym mieście (w tym beach barów) ma kwestia własności. Oba cele są powiązane, pozwalając na sprawdzeniu początkowego założenia. Ważnym wnioskiem z przeprowadzonych badań jest to, że w ocenie przestrzeni nastawionej na długi pobyt ludzi dużo bardziej istotna niż kwestia własności wydaje się dzisiaj swoboda zachowania, a o nią z pewnością jest trudniej w przestrzeniach miejskich niż w nawet ogrodzonej, ale pomysłowo pomyślanej przestrzeni beach barów. Warta uwzględnienia jest również kwestia (braku) „swojskości”, inaczej mówiąc, relacja pomiędzy zakresem kontroli a swobodą zachowania, a ponad wszystko swobodą decydowania – możliwością podejmowania samodzielnych, nienarzucanych wyborów.
    The article presents a continuation of research on the space of beach bars in Wrocław, observed in 2018, which was aimed to evaluate the space of these places with a particular focus on their operation (program + function). The results of the evaluation were compared with the official public spaces of the city. The main aim of this juxtaposition was to show the most significant similarities and differences between the two types of spaces and thus to explore the strengths and weaknesses of urban spaces, which could be helpful in their enrichment and development. Particular attention was paid to all those elements of the programme and functions which could strengthen social interaction – living in these spaces. An indirect aim was to answer the question raised in the title of the importance of ownership for the operation of spaces in a contemporary city (including beach bars). Both objectives are linked, allowing to check the initial assumption. An important conclusion from the research carried out is that in the assessment of residency-oriented space – the long stay of people, much more important, apart from the possibility of meeting different needs, seems to be the freedom of behaviour today, and this is certainly more difficult in urban spaces than in even fenced, but ingeniously conceived beach bar spaces. The issue of (lack of) “familiarity”, in other words the relationship of dependence between the scope of control and the freedom of behaviour and above all the freedom to decide – the possibility of making independent, not imposed choices, is also worth considering.

    Opis:
    The oxygen consumption of a sandy beach interstitial community was determined on four occasions (January, May, August, October) on the Gulf of Gdańsk (southern Baltic Sea). The study was carried out at four locations on the beach slope (littoral, waterline, splash zone and middle beach). Oxygen consumption varied from 158–159 cm3 O2 m−2 h−1 at the underwater site and waterline to 20–36 cm3 O2 m−2 h−1 in the middle beach. According to these data, interstitial organisms are able to utilize from 206 to 1641 mg of organic carbon per square metre per day. In general, metabolic activity decreased gradually from the waterline towards the middle beach, and a significant correlation was found between oxygen consumption and sediment water content. Changes in oxygen consumption on the beach slope were statistically significant.

    Concentrations of metals, i.e. As, Cd, Cu, Mn, Ni, Pb, Zn were analysed in bottom deposits of a marine port in Ustka and within the adjacent beach sections. Metal concentrations within the port channel may be ordered in terms of increasing values as: Cd < As < Ni < Zn < Cu < Pb < Mn. Heavy metal concentrations detected in port sediments were much higher than those in beach deposits. Samples of surface waters were also collected from the port channel, harbour basins and nearby beaches and selected physico-chemical indexes were determined, including heavy metal concentrations.
    Wykonano analizy stężenia metali As, Cd, Cu, Mn, Ni, Pb, Zn w osadach dennych portu morskiego w Ustce oraz w sąsiadujących odcinkach plaży. Stężenia metali w obszarze kanału portowego tworzyły stężeniowy szereg rosnący: Cd < As < Ni < Zn < Cu < Pb < Mn. Uzyskane stężenia metali ciężkich w osadach portowych były znacznie wyższe niż w osadach plażowych. Z kanału portowego, basenów portowych oraz w pobliżu plaż pobrano również próbki wody powierzchniowej, w których przeanalizowano stężenie wybranych parametrów fizykochemicznych, w tym metali ciężkich.

    Opis:
    This study was carried out to determine the water quality of the beaches at Matrouh, south-eastern Mediterranean Sea, Egypt, by studying environmental variables as well as phytoplankton abundance and community structure. Surface water samples were monitored from a series of beach sites over a period of five seasons during 2009–2010. A total of 203 phytoplankton species were identified from seven algal divisions. Seasonal differences in the quantitative and qualitative composition of the phytoplankton communities in the different sites were marked. Nutrient concentrations and phytoplankton abundances were found to be poorer than those of many other areas along Egyptian coast. The Shannon-Wiener Diversity Index classified Matrouh water as being between clean and moderately polluted, whereas the WQI demonstrated that it was between good and excellent. It can be concluded that the index based onWQI is currently more suitable than the phytoplankton species index for assessing the quality of the water of the Matrouh beaches.

    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 study considered two ecologically similar coastal areas in Tuscany (Italy). One site belongs to a protected natural area and the other one is in front of a camping site. We analysed the impact of human activities, such as trampling and mechanical beach cleaning, on Talitrus saltator. It turned out that the population density was affected in that it first disappeared from the area at the camping site, then recolonised it once the peak of the tourist season at the camping site had passed. The results confirm the sensitivity of this species and its plasticity in adapting to different conditions on the one hand, and the positive effects of diversification in resource management on the other hand.

    Opis:
    The presence of infragravity waves in nearshore regions can be sought in the records of both water levels and wave-driven longshore currents. For this reason, time series of such currents in close proximity to the shoreline were analysed using Singular Spectrum Analysis (SSA). Simultaneously, the results obtained with this method were confronted with the output of Discrete Wavelet Transform (DWT), which had previously been applied to this data. The records of longshore currents were collected on a daily basis during field experiments in the autumns of 2002 and 2003 with sampling rates of 3 Hz and 0.5 Hz. This produced a large data set that allowed for the use of an advanced signal processing technique, capable of extracting patterns characteristic of low-, medium- and high-frequency bands. It provided similar evidence to that produced by DWT for the existence of infragravity waves along a dissipative coast with multiple bars. The study also demonstrated the utility of SSA for studies on coastal hydrodynamics. It also showed up the better user-friendliness of DWT in terms of pattern extraction and interpretation. On the other hand, SSA demonstrated a higher precision of pattern extraction once the DWT output was known, which is a manifestation of the synergy of the two methods when applied jointly.

Badania przeprowadzono na specjalnych stanowiskach służących do pomiarów momentów sił w warunkach statyki. Badane grupy zawodników różniły się wysokością i masą ciała, jednak uzyskane wyniki pozwalają przypuszczać, iż zawodnicy obu dyscyplin charakteryzują się podobnymi wartościami względnej, maksymalnej siły mięśniowej i topografii momentów sił.
    This study presents a comparison of volleyball (n = 24) and beach volleyball (n = 20) players, in terms of maximal muscle torques for 10 muscle groups. The measurements were taken on a specific mechanical stands that were designed and built for measuring muscle torques under isometric conditions. Body mass and body height differed in examined groups significantly; however obtained results suggest, that players of both disciplines rather have similar level of relative muscle strength and a strength distribution.

    Opis:
    Sandy sediments coming from three beaches of the southern Baltic Sea were collected and analyzed. Investigated beaches were divided according to strength of anthropogenic impact and degree of sheltering. The first beach was situated in Ustka on the eastern side of the mouth of the Słupia River, second in Czołpino and the last one in Puck. Core sediment samples were collected seasonally, depending on the influence of the sea water on the examined sediments. At each station, surface sediments (0-5 cm) were collected as well as sediments at the depth of 10-15 cm. The general content of organic matter, proteins, lipids, carbohydrates, organic carbon and total bacterial number were determined. The results of the conducted tests reveal, that anthropopressure, degree of sheltering, the depth where the collected sediments were taken and the direct influence of the sea water on the sediments have impact on the chemical composition of organic matter and bacterial number in beach sediments.

Pierwsza plaża położona była w Ustce we wschodniej części ujścia rzeki Słupi, druga w Czołpinie, a ostatnia w Pucku. Próbki osadów plażowych zbierano sezonowo, w zależności od wpływu wody morskiej na badane osady. Na każdym stanowisku pobierano osady powierzchniowe (0-5 cm), a także osady na głębokości 10-15 cm. Określono zawartość materii organicznej, białek, lipidów, węglowodanów, węgla organicznego i całkowitej liczby bakterii. Wyniki przeprowadzonych badań wykazały, że antropopresja, stopień osłonięcia plaży, głębokość pobieranych osadów i bezpośredni wpływ wody morskiej na osady oddziałują na skład chemiczny materii organicznej i liczbę bakterii w osadach plażowych.

    Opis:
    The study objective was to analyse the number of tourists present in the shore zone and bathing areas of lakes with regard to their tourist carrying capacity and the amount of biogenic substances potentially entering the ecosystem from the beach and bathing areas. The procedures from project between the EU and Poland, in the module “Development of the sanitary supervision of water quality” were used in three categories: physiological substances - sweat and urine; water-soluble and insoluble organic compounds; and biogenic elements - nitrogen and phosphorus. The research was conducted in two model mesotrophic lakes, Piaseczno and Zagłębocze, located in the Łęczna-Włodawa Lakeland (eastern Poland). The data were analysed in reference to biological trophic status indices defining the limnological status of lakes in the summer of 2014 and 2016. Analyses of gross primary production of phytoplankton using the light and dark bottles method and the analysis of chlorophyll a concentration were applied using the laboratory spectrophotometric method. The relatively small number of tourists recorded in the shore zone of both lakes did not exceed their tourist carrying capacity, and their potential contribution of biogenic substances to the lake ecosystems was small. Biological trophic indices for both lakes indicated that they had been continually late-mesotrophic for decades. The amount of biogenic substances directly linked to beach tourism usually has a minor effect on the limnological status of mesotrophic lakes. Due to the specific character of lake ecosystems, however, even small amounts of these substances can contribute to the destabilisation of the biocenotic system.

    Opis:
    The article analyses the imbalanced power-relations between the native inhabitants and the British colonizers in the South Pacific Isles as portrayed in Robert Louis Stevenson’s South Sea Fiction. It is argued that parallel to Stevenson’s detailed historical descriptions of the isles, the South Sea Fiction engages critically with the British colonial discourse as well as with the ideologically-informed accounts of the isles that had been circulat- ing in Europe following James Cook’s expedition. In the resulting fabulous entanglement of the white man’s narratives and the native stories, the disproportion in powers gives advantage to the white man’s sinister tales.

    Opis:
    This study is dedicated to Wast Water Lake (Northwest England, Great Britain) and the character of its beach sediments. The aim of the study is to identify the textural features of the lake’s beach sediments based on two methods. The first is a granulometric analysis and the second a pebble shape analysis according to Zingg (1935) and Sneed & Folk (1958). Both analyses were carried out for all of the lake’s accessible beaches and the cliffs adjacent to them. The transport and deposition history of the examined sediments was identified through field research and laboratory analysis. The results show that the textural features of the sediments at Wast Water are more often typical of a fluvial environment, rather than having been changed by lacustrine water movements.

    Opis:
    The study focuses on sand grain properties in different parts of a beach-dune system built entirely of heavy mineral particles. These properties are related to: (1) resistance of particular minerals to weathering and abrasion, (2) hydraulic sorting in the swash zone, and (3) aeolian sorting during grain transport inland from the upper beach. The main waterlain and windlain sand properties depend on settling velocity which results from grain density (reflecting grain mineralogy), size, shape and roundness. The study was performed on the beach and dunes at Patea on the west coast of the North Island of New Zealand, which are comprised of heavy minerals assemblage containing a ferromagnetic (dominated by titanomagnetite) and non-ferromagnetic (mainly pyroxene and amphibole) fractions. The result demonstrates that three zones of different sand properties can be distinguished: (1) a lower swash zone dominated by non-ferromagnetic, larger and more angular particles which are carried back from the upper swash zone down the foreshore by the backwash; (2) an uppermost swash zone and beach with almost 100% of ferromagnetic, smaller and more rounded particles deposited at the back of the beach by the uprush, which during high tide and storms can reach the cliff toe, and can be reworked by wind; and (3) a climbing dune composed of a more poorly sorted mixture of non- and ferromagnetic particles. In terms of both mineralogy and grain size and shape, the dune sand is less uniform than the beach sand. Aeolian segregation resulted here in sand textural features opposite to those found in dune sands composed of light minerals. The results highlight the density-dependent variability of grain size and shape of beach-dune deposits consisting of only heavy minerals, and broaden our understanding of mechanisms of sedimentary processes which is particularly important when reconstructing older sedimentary successions.

    The paper presents the results of studies on the qualitative and quantitative features of the littoral drift at Golden Sands (Bulgaria), carried out jointly by Polish and Bulgarian researchers. The mathematical modelling of physical coastal processes took wave transformation (wave diffraction and refraction; the effects of shoaling and wave breaking) and longshore sediment transport into account. The computations were carried out for the mean statistical annual wave climate, determined on the basis of IO BAS wave data, simulated using the WAM method from long-term Black Sea wind data. The results of sediment transport computations clearly show that its direction off the Golden Sands shore is from north to south.

    Opis:
    The transformation of long water waves arriving at a sloping beach is investigated. An approximate theory is presented for plane periodic waves propagating in water of non-uniform depth. The theoretical description of the phenomenon, based on certain kinematic assumptions, is formulated in the material variables, and the solution is constructed by applying the Hamilton variational principle. In order to assess the accuracy of the formulation and to learn more about long wave transformation, experimental measurements were carried out in a laboratory flume. In the experiments, a water wave, generated by a piston-type wave maker placed at one end of the flume, propagated towards a rigid inclined ramp installed at the other end of the flume. The wave transformation along the direction of its propagation was recorded by a set of wave gauges installed along the flume. The wave run- up on the sloping beach was measured with a special conductivity gauge placed alongside the ramp. Comparison of the theoretical results with experimental data indicates that the proposed theoretical formulation provides a good description of the main features of wave transformation behaviour over a sloping beach, except in the vicinity of the shore point, where some discrepancies occur.

    Opis:
    Based on observations spanning 21 years (2000–2020), the article studies the effects of storm surges on the shore of the Świna Gate Sandbar in the southern part of the Pomeranian Bay (southern Baltic Sea). Impacts of selected maximum storm surges in each year were assessed with respect to morphological data collected on the beach and the foredune. The data included parameters of beach-dune erosion as measured along a beach transect before and after each surge. Differences and trends in the shore erosion were related to the sea level (SL), duration of a storm surge [highest storm sea level (HSL) > 1 m], wind-wave sector and wave run-up. The relationships were explored using a sim- ple correlation analysis. The most serious erosion was observed during the heaviest surges [HSL > 1.3 m above the mean sea level (AMSL)], with a wave run-up higher than 3.2 m AMSL. Such surges occurred at about 2-year intervals. The average SL during a surge was 1.2 m AMSL, with a run-up of 2.6 m AMSL. The beach and the lower part of the shore, below that level, were eroded each year. The heaviest surges resulted in an average 5.2 m and 7.0 m dune retreat on the high-beach-accumulative shore and on the low-beach-erosive shore, respectively. The dune was not eroded when the beach height exceeded the wave run-up. The heaviest surges eroded away 12–14 m3 of the beach sand volume. The shore erosion was found to be related to the storm surge duration, the maximum SL, the run-up and the beach height prior to the surge.

    Opis:
    Within the framework of the MEDCORE project on the ecology and management of Mediterranean coastal areas we decided to include the local dissemination of scientific results in Tunisia. The involvement of a local public school, and the joint work of local teachers and of local and international researchers, was chosen as a dissemination method because of the role of the school as an educational centre and the natural interest and curiosity characterising the schoolchildren. As the subject of the experience of dissemination a beach-dune system was considered suitable because of it was near, familiar and easy to reach, and also because of the economic importance of such environments, which generate considerable income as a result of tourists frequenting them. In environmental education, however, less emphasis is placed on this particular environment. A test performed before and after a school trip to the beach showed an increase in knowledge among children about beach-dune systems. Correlations between the gender and background of the children with their previous knowledge and information acquired from the field experience were analysed, and found to be not significant. All the children were equally receptive to environmental issues, regardless of their gender or background (urban/rural environment). One of the main results obtained through this experience is the effectiveness of sharing knowledge with local people, as stakeholders of study sites. The next step in the process of disseminating scientific knowledge for the benefit of the local community should be to examine its possible long-term effects.

    Opis:
    Lake Vortsjärv is one of the biggest lakes in Eastern Europe and possesses a complex geological history. Bottom deposits consist mostly of fine sand and silt, accompanied with sapropel (up to 9 m thick) and lake marl (up to 8 m thick). In places, especially in the northern part where the bottom deposits are absent, varved clay or till are exposed in the lake basin. In the southern part of the lake the deposits are much thicker, indicating a gradual rise of water-level. Like the majority of lakes in the Northern Hemisphere, Lake Vortsjärv possesses a more open eastern and a more swampy and overgrown western bank. Shore types and the lithological composition of shore sediments are varied and highly controlled by the bedrock and glacial deposits. Long-shore transport of sediments is limited. The mineral composition of bottom sediments shows great qualitative and quantitative variability which relates to the grain-size and petrography of the parent deposits. Organic-rich sapropel can be used in agriculture and evidently also for medicinal purposes.

The nematodes were identified to the genus level and assigned to appropriate trophic group. The density of free-living nematoda varied from 10.52 ± 9.82 ind./10 cm2 to 124.49 ± 76.39 ind./10 cm2. Ascolaimus was the most abundantly represented genus, accounting for from 45% to 74% of the total number of nematofauna. A total of 7 nematode genera were identified. Ascolaimus, Axonolaimus, Enoplolaimus and Daptonema were considered essential elements of nematofauna. In terms of functionality, non-selective deposit feeders were predominant, individuals with unarmed buccal cavity, represented by nematodes of the genera Ascolaimus, Axonolaimus, Theristus and Daptonema.

    Opis:
    A total of over 550 samples of particulate organic matter (POM) were obtained from swash and groundwater samples taken on a monthly basis from seven localities on the sandy shores of Puck Bay in 2002 and 2003. Sandy sediment cores from the swash zone were collected to assess the amount of POM in the pore waters. The mean annual concentrations of POM varied between localities from 20 to 500 mg in groundwater and from 6 to 200 mg dm−3 in swash water. The carbon/nitrogen (C/N) ratio in suspended matter was always higher in groundwater (annual mean 12) than in swash water (annual mean 7). The C/N ratio indicates a local, algal origin of POM in the shallow coastal zone.

    Opis:
    The effects of the beach community structure of macro- and meiofauna on the process of beach wrack decay were investigated by means of a simple field colonisation experiment in a temperate, fine quartz sediment, sandy beach at the end of the Hel Peninsula in Poland. 1260 replicate litterbags of three mesh sizes (12 mm, 0.5 mm, 48 μm) containing fresh wrack were used to assess the role of faunal and non-faunal components in the breakdown of stranded Zostera marina. Wrack breakdown was determined during a three-year field study. This paper presents the first part of the results of this field experiment, which refer to the effects of fragmentation detritivory, leaching and decay rates. Material was lost from the bags at a rapid rate, with only 22–32% of the original dry mass remaining after 27 days in the field. This degradation was not directly related to the faunal succession of the eelgrass tissue, which proceeded in two distinct phases throughout the study period. Exclusion of macrofauna from the wrack by the use of finer-mesh litterbags (< 1 mm) had no appreciable effect on the rate of dry matter loss. Microbial decay, and abiotic leaching and fragmentation are probably the major causes of seagrass weight loss from the litterbags.

    Opis:
    The aim of this study was to evaluate the amount of organic macrodetritus deposited on the sandy shores of the southern Baltic,an d to determine the type of washout material and their chemical composition (carbon and nitrogen). Over 900 samples of macrodetritus (particles retained on a 0.5 mm sieve) were collected from seven sampling locations along a 120 km stretch of coastline in Poland at monthly intervals in 2002. Analysis of the C and N content of several categories of detritus supplied information about seasonal changes in and the ageing of algal debris,an d indicated that the amount of carrion is constant; the latter is apparently always metabolised very rapidly. The annual deposition of macroalgal detritus on this coast was estimated at 15 000 tonnes fresh weight,t hat is around 75% of the primary production of filamentous macroalgae in Puck Bay. In comparison with the amounts of kelp deposited on sandy beaches in South Africa (Griffiths & Stenton-Dozey 1981),t he massive seaweed washouts on Mediterranean beaches (Morand & Briand 1996),or the deposition of algal mats in the northern Baltic (Norkko & Bonsdorff 1996a),t he quantities of macrodetritus on the shore in the study area are average,ev en allowing for the fact that the Baltic Sea is highly eutrophic (HELCOM 2005).

    Opis:
    The significance of distance along the beach-dune transect and different moisture conditions as regards the decay of Zostera marina leaf litter was investigated in simple field experiments in three temperate, medium- to fine-quartz-sediment, sandy beaches of the Gulf of Gdańsk in Poland. 1800 replicate litterbags of freshly stranded Zostera marina leaves were placed in beach sediments at different strata and levels on each of the beaches. The litterbags were sampled after 5, 10, 50, 100 and 150 days in the field and the remaining material was then dried and weighed. Under similar conditions of sediment composition, salinity and wave inundation, ANOVA tests revealed significant differences in breakdown through time and site. Thus there were some differences in the decay process between the low and high beach. In the former, degradation proceeded rapidly in the initial stages and then stabilised, while in the latter it remained linear throughout the study period.Matter loss in each stratum was also seasonally dependent. This may, however, be more closely linked to successional changes in the chemistry and/or microflora of the beach wrack than to its physical breakdown. Differences between organic matter degradation in the high and low beaches may be explained by differences in the moisture regime and nutrient status, and not by differences in the decay processes themselves. Therefore, two decay centres were found in the beach-dune system: the low beach together with the strandline (wrack consumption 12–21 % day−1 in the warm season, and 4–10 % day−1 in the cold season) and the dune (active consumption 2–6 % day−1 in the warm season only).

    Opis:
    Grain size studies of sediments from beaches in the region from Mandapam to Kanyakumari, divided into 5 sectors, indicate that sediments are unimodal to polymodal in nature, coarse to fine grained, moderately to poorly sorted, and positively-negatively skewed in character. The inference to be drawn from these studies is that the variation in sedimentological parameters is governed by fluvial input, wave dynamics, and littoral transport of the sediments. Bivariant plots show that the Mandapam and Kanyakumari sectors can be classified as beach environments, whereas the Tuticorin and Valinokkam sectors come under the influence of riverine environments and the dune environment in the Manappad sector. The CM pattern of all five sectors shows a clustered distribution of sediments in the PQ and QR segments, indicating a graded mode of deposition. Visher diagrams depict a wave shadow environment for the Mandapam sector, whereas the Valinokkam, Tuticorin and Manappad sectors show double saltation populations characteristic of beaches, and the Kanyakumari sector is characterized by a more truncated population characteristic of a plunge zone, which is a high-energy environment.

    Opis:
    The paper describes lithodynamic and morphodynamic processes occurring in the main part of the south-eastern Baltic coastal area, namely on the sea shores from the Vistula mouth in the Gulf of Gdansk to the Lithuanian-Latvian border. The study area is subject to intensive natural coastal changes, as well as shore evolution caused by anthropogenic impacts at several locations. Methods of coastal protection against erosion and shore stabilization systems applied in the past and currently are described. The paper deals with the causes of the dynamics of beach/dune shores and cliffs. It presents the authors’ field observations of 2010-2013, as well as previously gained knowledge and the results of Polish, Russian and joint Polish-Russian field surveys.

    Opis:
    This study was conducted in July 2016 around Putri Island and Cikiong Beach, Batujaya District, Karawang Regency, West Java - Indonesia to know the types of surficial sedimentary that makeup Putri Island. Field survey activities were carried out to collect sediment samples using a 1-meter long piston core. The sampling locations were carried out at five stations by considering representativeness and ease of accessibility. Sediment analysis using the sieve or granulometric method to produce grain size information on the phi (φ) scale. Sediment types were classified based on grain size using the Wentworth scale and followed by the Folk’s ternary diagram. The study results show that the sediment covering the bottom of the waters around Putri Island is composed of seven types of sediment, namely gravel, very coarse sand, coarse sand, medium sand, fine sand, very fine sand, and silt. It can be seen that sand dominates the sediment fraction which reaches 94% followed by 4% mud and 2% gravel. If classified based on the main component of the Folk’s ternary diagram, the seabed of this area has three types of sediment textures, namely slightly gravelly sand [(g) S], Sand [S], and gravelly sand [gS]. Judging from the constituent elements of the sediment, it can be said that the sedimentation that occurs in the study location is composed of alluvial deposits. The formation of this sediment is dominated by material carried by the river flow through fluvial and tidal processes.

    Opis:
    The study, carried out in 2003 and 2006 at the Lubiatowo Coastal Research Station (Poland), located on the non-tidal southern Baltic coast (tidal range < 0.06 m), focused on larger rhythmic forms (mega-cusps) with wavelengths in the interval 500 m > Lc > 20 m. Statistical analyses of detailed shoreline configurations were performed mostly with the Discrete Wavelet Transform method (DWT). The beach is composed of fine sand with grain diameter D50 ≈ 0.22 mm, which produces 4 longshore sandbars and a gently sloping seabed with β = 0.015. The analysis confirms the key role of bars in hydro- and morphodynamic surf zone processes. The hypothesis was therefore set up that, in a surf zone with multiple bars, the bars and mega-scale shoreline rhythmic forms form one integrated physical system; experimental evidence to substantiate this hypothesis was also sought. In such a system not only do self-regulation processes include swash zone phenomena, they also incorporate processes in offshore surf zone locations. The longshore dimensions of large cusps are thus related to the distances between periodically active large bed forms (bars). The spatial dimension of bar system activity (number of active bars) depends, at a given time scale, on the associated hydrodynamic conditions. It was assumed that such a time scale could include either the development and duration of a storm, or a period of stable, yet distinct waves, capable of remodelling the beach configuration. The indentation to wavelength ratio of mega-cusps for the studied non-tidal dissipative environment may be one order of magnitude greater than for mesotidal, reflective beaches.

    Purpose: The study reported in this article sought to examine the current state of Botutonuo Beach in the Province of Gorontalo, Indonesia, and develop a digital-based marketing strategy that allows attractions of the beach to be open to potential worldwide tourists. The beach is a popular tourist destination in the province, yet limited information about the beach is available online. Design/Method/Approach: A design-based research method was employed in the study. To collect data, observations and semi-structured interviews with four locals who were also organizing the beach were used; while for the analysis, a thematic analysis approach was utilized. Findings: Findings revealed three main themes that best describe aspects of Botutonuo Beach tourism sites that need improvement, namely accessibility, facilities, and convenience, as well as showed what important information that needs to be included on the beach website. Practical Implications: It is expected that the website can be used by the beach management and local government to foster the promotion of Botutonuo Beach. It is also hoped that the findings, in general, may encourage active participation by the beach visitors and local government to ensure effective management of the beach so that national and international recognition can be obtained. Originality/Value: The study proposed development of a website that helps in promoting Botutonuo Beach as one of the popular tourist destinations in Gorontalo. Research Limitations/Future Research: Future research examining the efficacy of this website development is a potential research topic to undertake. Botutonuo Beach is a popular tourist destination in the Province of Gorontalo, Indonesia. The locals have primarily been managing the beach for years; however, very little information can be elicited about it online by target visitors from other regions. Therefore, the study reported in this article sought to examine the beach’s current state and develop a digital-based marketing strategy that allows attractions of the beach to be open to potential worldwide tourists. Using a design-based research method, data were collected using observations and semi-structured interviews with four locals who were also organizing the beach. To analyze data, a thematic analysis was used. Findings revealed that several things related to accessibility, facilities, and convenience were crucial aspects to be considered by the beach management. Furthermore, developing a website that helps the management promote the beach’s uniqueness is necessary. The study suggests that the locals, visitors, and government share the responsibility to ensure more effective beach management.
    Мета роботи: Дослідження, про яке йдеться в цій статті, спрямоване на вивчення поточного стану пляжу Ботутонуо в провінції Горонтало, Індонезія, та розробку маркетингової стратегії на основі цифрових технологій, яка дозволить відкрити атракції пляжу для потенційних туристів з усього світу. Пляж є популярним туристичним напрямком у провінції, проте в Інтернеті доступна обмежена інформація про нього. Дизайн / Метод / Підхід дослідження: У дослідженні було застосовано дизайн-метод дослідження. Для збору даних використовувалися спостереження та напівструктуровані інтерв'ю з чотирма місцевими жителями, які також займалися організацією пляжу; для аналізу використовувався підхід тематичного аналізу. Результати дослідження: Виявлено три основні теми, які найкраще описують аспекти туристичних об'єктів пляжу Ботутонуо, що потребують покращення, а саме: доступність, зручності та зручності, а також показано, яку важливу інформацію необхідно включити на веб-сайт пляжу. Практична цінність дослідження: Очікується, що веб-сайт може бути використаний керівництвом пляжу та органами місцевого самоврядування для сприяння просуванню пляжу Ботутонуо. Також є надія, що отримані результати, в цілому, можуть сприяти активній участі відвідувачів пляжу та місцевої влади для забезпечення ефективного управління пляжем, щоб отримати національне та міжнародне визнання. Оригінальність / Цінність дослідження: Дослідження запропонувало розробку веб-сайту, який допоможе у просуванні пляжу Ботутонуо як одного з популярних туристичних напрямків у Горонтало. Обмеження дослідження / Майбутні дослідження: Майбутні дослідження, що вивчають ефективність розробки цього веб-сайту, є потенційною темою для проведення досліджень. Пляж Ботутонуо – популярне туристичне місце в провінції Горонтало, Індонезія. Місцеві жителі в основному керують пляжем протягом багатьох років; однак, дуже мало інформації про нього можна отримати в Інтернеті для цільових відвідувачів з інших регіонів. Тому дослідження, про яке йдеться в цій статті, мало на меті вивчити поточний стан пляжу та розробити маркетингову стратегію на основі цифрових технологій, яка дозволить відкрити пам'ятки пляжу для потенційних туристів з усього світу. Використовуючи дизайн-метод дослідження, дані були зібрані за допомогою спостережень та напівструктурованих інтерв'ю з чотирма місцевими жителями, які також займаються організацією пляжу. Для аналізу даних було використано тематичний аналіз. Результати показали, що деякі речі, пов'язані з доступністю, зручностями та зручностями, є вирішальними аспектами, які слід враховувати керівництву пляжу. Крім того, необхідна розробка веб-сайту, який допоможе керівництву просувати унікальність пляжу. Дослідження припускає, що місцеві жителі, відвідувачі та уряд поділяють відповідальність за забезпечення більш ефективного управління пляжами.

    Opis:
    Alexandrian Seashells is a poetic collection of Mona Latif-Ghattas, where we try to study the dream image of the sea; poet recounts her memories of youth, stranded as seashells on the beach. Hypotyposis is the best figure of speech that reflects poetic hallucinated impulses, symbolic elusive relationships or inexpressible feelings. Essentially descriptive, this figure is based on the observation of feelings, sensations or elusive impressions. It transmits the fleeting thoughts by its dynamic appearance. The multiple facets of hypotyposis, spread through the space-time items, include figures attached either to land, desert, beaches or fluid figures that derive their value from the sea. The hypotyposis is able to connect the lived memories with the emotional effect produced by the moment.
    Écailles Alexandrines, recueil poétique de Mona Latif-Ghattas, où l’on tente d’étudier l’image onirique de la mer; la poétesse y retrace ses souvenirs de jeunesse, ramassés comme des coquillages échoués sur les plages. L’hypotypose est la meilleure figure qui reflète les élans poétiques hallucinés, les rapports symboliques qui soulignent l’inexprimable. Essentiellement descriptive, elle se fonde sur l’observation des sentiments, des sensations ou des impressions mobiles et changeants. Les multiples facettes de l’hypotypose se répandent à travers les éléments spatiaux, regroupant les figures attachées soit à la terre, au désert, aux plages ou les figures fluides. L’hypotypose tresse les souvenirs vécus avec les états d’âme produits par l’effet du moment.

    Background. The article concerns high level beach volleyball players’ actions and in particular the issues of evaluation. The main object of the analysis is the setting which seems to be an action that can increase the efficiency of the attack. It was assumed that setting skills are very important part of synergistic potential of players. Material and methods. In process of evaluation an original method of observation and a modern approach based on the evaluation criteria of players’ skills proposed by Panfil was used. The study was based on three criteria: correctness, diversity and flexibility. Research materials were the recordings of 12 men’s beach volleyball matches played during the top international tournaments of the 2011 and 2012 FIVB Beach Volleyball SWATCH World Tour. Results. We recorded the number of actions, average level of correctness, diversity and flexibility for each of the selected 20 players. Flexibility was determined by two indexes: dependent flexibility and independent flexibility. Conclusions. It is essential to provide important aspects of the game characteristics and prepare hints for the training process designed for top beach volleyball teams, based on the solutions used by the best teams in the world. Additionally, the paper discussed and verified new tools that expand the general criteria of players’ skills evaluation proposed by Panfil specifically to beach volleyball.

    Opis:
    The present study discusses results of heavy mineral analyses and radioactivity of beach sediments of Lake Peipsi. Such analyses are commonly done globally, but had not yet been conducted for the fourth largest lake in Europe. The average heavy mineral content in Lake Peipsi beach sediments along the northern and western coast is higher than usual for Estonian coastal and Quaternary sediments. Concomitantly, elevated radioactivity levels have been measured in several places, with the highest concentrations observed at Alajõe (1885.5 Bq/kg), which is over five times more than the recommended limit. The aim of the present study is to find sites with higher radioactivity levels, because the northern coast of Lake Peipsi is a well-known recreational area.

    Opis:
    This article does not contain abstracts in English.
    Celem tej pracy jest omówienie przestrzennych i krótkotrwałych zmian w morfologii plaży pod kątem grzbietów i strumieni na podstawie profili plaży w Vembar, na wybrzeżu Kallar, Tamil Nadu, Indie. Plaże składają się głównie z średniego do grubego piasku i ciężkich minerałów. Dla plaż charakterystyczne są grzbiety, strumienie i zagłębienia. Grzbiety i strumienie są niewielkie ze względu na prace kopalniane prowadzone w okolicy. Ustalono, że przestrzenne i tymczasowe zmiany w systemie grzbietów i strumieni są kontrolowane przez pianę morską/łamiące się fale. Zmiany objętości sedymentu wynikają z nieregulowanej aktywności kopalni. Erozja ma wpływ na profil wszystkich plaż, zwłaszcza strumieni. Strefy przyrostu znajdują się wyżej, to znaczy na najwyższych grzbietach i wałach plażowych. Krótkotrwałe zmiany wielkości plaży wyjaśniają zniekształcenie grzbietów i strumieni. Ma to związek z pobliską kopalnią. Zaobserwowano wzorzec wiatru wyżej plaży, gdzie warunki pozwalają na transport sedymentu piasku i jego ruch na grzbietach i strumieniach.

    Opis:
    Aim of works on morphology and morphometry of the coastal zone is identification of qualitative and quantitative changes in the beach-dune strip and in the shoreface in conditions of their natural and anthropogenic transformations. As shore and backshore are essential elements reducing risks from the sea to the adjacent hinterland, this article focuses on evaluation of their parameters. Moreover, elements of the coast are described herein in detail. The research material used for the purposes of this article were records of bathymetric-tacheometric measurements of the Polish coast, made at consistent profiles evenly spaced every 500 m. The measurements did not cover the areas adjacent to the Bay of Gdańsk or the Lagoons. This article presents an analysis of the measurements of components of the coastal zone, which covered four morphodynamical areas (the Hel Peninsula, Jastrzębia Góra – Jarosławiec, Jarosławiec – Sarbinowo, and Sarbinowo – Międzyzdroje), twelve sandbar stretches (the Helska, Karniewska, Sarbska, Łebska, Długie, Gardno, Wicko, Kopań, Bukowo, Jamno, Resko, and Dziwnowska Spits) and thirteen cliff stretches (the cliffs in Chłapowo, Jastrzębia Góra, Rowy, Dębina, Ustka, Jarosławiec, Wicie, Sarbinowo, Ustronie Morskie, Śliwin, Trzęsacz, Pobierowo, and on Wolin Island). The basic linear parameters of the beach-dune and beach-cliff belt were read from 678 printouts of tacheometric profiles. A detailed analysis carried out in this manner made it possible for the endangered sections of the coast to manifest themselves. The obtained data are a basis for further comparative analyses, and assessment of the shore under conditions of implementation of the Act on the Protection of Sea Coasts.
    Celem prac nad morfologią i morfometrią strefy brzegowej jest poznanie jakościowych i ilościowych zmian zachodzących w pasie plażowo-wydmowym i na podbrzeżu w warunkach ich naturalnych i antropogenicznych przekształceń. W artykule skupiono się na ocenie parametrów brzegu i nadbrzeża, jako znaczących elementów redukujących zagrożenie przyległego zaplecza od strony morza. Ponadto opisano szczegółową charakterystykę elementów wybrzeża. Materiałem badawczym były zapisy pomiarów batymetryczno-tachimetrycznych polskiego wybrzeża, w stałych profilach rozmieszczonych co 500 m. Pomiary nie objęły swoim zasięgiem obszarów przylegających do Zatoki Gdańskiej czy zalewów. W artykule przedstawiono analizę pomiarów elementów strefy brzegowej, które objęły cztery rejony morfodynamiczne (Półwysep Hel, Jastrzębia Góra- -Jarosławiec, Jarosławiec-Sarbinowo oraz Sarbinowo-Międzyzdroje), dwanaście odcinków mierzejowych (Helska, Karniewska Sarbska, Łebska, Długie, Gardno, Wicko, Kopań, Bukowo, Jamno, Resko i Dziwnowska) i trzynaście odcinków klifowych (chłapowski, jastrzębski, rowski, dębski, ustecki, jarosławiecki, wicki, sarbinowski, ustroniomorski, śliwiński, trzęsacki, pobierowski i woliński). Na wydrukach 678 profili tachimetrycznych odczytano podstawowe parametry liniowe pasa plażowo-wydmowego i plażowo-klifowego. Tak przeprowadzona szczegółowa analiza wybrzeża pozwoliła na uwidocznienie zagrożonych odcinków. Uzyskane dane stanowią podstawę do dalszych analiz porównawczych i oceny stanu brzegu w warunkach wdrażania zapisów ustawy o ochronie brzegów morskich.

    Opis:
    Bursztyn jest kopaliną, która jest objęta prawem własności gruntowej. Wyjątek dotyczy złóż znajdujących się poza granicami nieruchomości gruntowych, w tym w obszarach morskich. Stanowią one przedmiot własności górniczej, która przysługuje Skarbowi Państwa. „Połów bursztynu” polega na zbieraniu bryłek bursztynu wypłukanego ze złóż podmorskich i znajdującego się pod wodą na niewielkiej głębokości obok linii brzegu. Przedmiotem prawa geologicznego o górniczego jest m.in. poszukiwanie (rozpoznawanie) oraz wydobywanie kopalin ze złóż. Wiele wskazuje na to, że opisane wyżej nagromadzenia bryłek bursztynu nie mogą być uważane za złoża w rozumieniu prawa geologicznego i górniczego. W konsekwencji ich „połów” nie będzie wymagał spełnienia przesłanek określonych wspomnianym prawem. Niejasny stan prawny powoduje natomiast, że ustalenie szczegółowych wymagań dotyczących omawianej działalności jest trudne.
    Amber is a mineral covered by the land ownership right. The exception applies to deposits located outside the spatial borders of the land, including ones located within the borders of maritime areas. They are covered by mining ownership, vested in the State Treasury.„Amber fishing” consists in collecting amber nuggets washed out of submarine deposits and located under water at a small depth near the shoreline. The subject of Geological and Mining Act is, among others, prospecting for (exploration) and mining of minerals from deposits. There are many indications that the above-described amber nuggets cannot be considered as a deposit within the meaning of Geological and Mining Act. As a consequence, „fishing” them will not require fulfilment of the requirements set out in the aforementioned Act. However,the unclear legal situation means that it is difficult to determine detailedrequirements regarding the activity in question.

    Opis:
    Po odzyskaniu przez Polskę w 1918 r. niepodległości podjęto szereg działań legislacyjnych mających na celu unormowanie zagadnień związanych z kąpieliskami. W polskim języku prawnym termin kąpielisko posiadał w okresie międzywojennym dwa znaczenia: sanitarne – zakładów kąpielowych (publicznych łaźni, miejsc utrzymania higieny) oraz miejsc, miejscowości wypoczynku nad wodą. Regulacje prawne miały w szczególności na celu unifikację pięciu pozaborczych systemów prawnych w jeden system. Wyjątkowe opóźnienia cywilizacyjne występowały na obszarze dawnego zaboru rosyjskiego. Szczególne przepisy obowiązywały w zakresie zakładów kąpielowych rytualnych dla ludności żydowskiej. Ustawa o uzdrowiskach z 1922 r. przewidywała szczególny reżim prawny dla kąpielisk morskich. Kolejnym źródłem regulacji było rozporządzenie o urządzeniu i utrzymywaniu zakładów kąpielowych publicznych z 1922 r., które regulowało, w ramach jednego aktu prawnego, tak „kąpieliska” w dzisiejszym znaczeniu tego słowa, jak i zespoły urządzeń sanitarnych służące utrzymaniu higieny. Kolejny ważny krok stanowiła ustawa wodna z 1922 r., która nie zawierała definicji legalnej terminu „kąpielisko”, ustanawiając jedynie zasadę powszechnego dostępu do wód publicznych. Ustawa ta wprowadziła, obowiązującą do dziś w kolejnych ustawach Prawo wodne, zasadę uzyskania zgody organów wodnoprawnych na otwarcie kąpieliska. Najpełniejsza w II Rzeczypospolitej regulacja kąpielisk w zbiornikach słodkowodnych i słonowodnych zawarta została w przepisach rozporządzenia o zakładach kąpielowych z 1936 r. Ten akt prawny obowiązywał już na obszarze całego kraju i regulował wszelkie instytucje kąpielowe, przeznaczone do publicznego użytku dla celów higienicznych, sportowych, a także rytualnych. W porządku prawnym Polskiej Rzeczpospolitej Ludowej oraz III RP kąpielisko występowało jako pojęcie wieloznaczne, odnoszące się zarówno do urządzenia sanitarnego, jak i miejsca do pływania do roku 1998.
    After Poland regained independence in 1918, a number of legislative measures were taken to regulate bathing-related issues. In the Polish legal language, the term bathing had two meanings in the interwar period: sanitary – bathing establishments (public baths, places of hygiene) and places to rest by the water. The legal regulation was aimed, in particular, at the unification of five post-partition legal systems into one system. Exceptional civilization delays occurred in the area of the former Russian partition. Special provisions were in force in the field of ritual bathing establishments for the Jewish population. The Act on health resorts of 1922 provided for a special legal regime for sea bathing areas. Another source of regulation was the Ordinance on the organization and maintenance of public bathing establishments of 1922, which regulated, within a single legal act, both „bathing areas” in the present meaning of the word as well as sets of sanitary facilities for maintaining hygiene. The next important step was the Water Act of 1922, which did not contain a legal definition of the term „bathing beach” also established the principle of universal access to public waters. This act introduced the principle of obtaining the consent of the water-legal authorities to open a bathing water, which is still binding in subsequent acts of the Polish Water Law. The most complete regulation of bathing sites in freshwater and saltwater reservoirs in the Second Polish Republic was contained in the Provisions of the regulation on bathing establishments of 1936. This legal act was already in force throughout the country and regulated all bathing institutions intended for public use for hygiene, sports, and also ritualistic. In the legal order of the Polish People’s Republic and the Third Republic of Poland, the bathing facility appeared as an ambiguous term, referring to the sanitary facilities and the place for swimming until 1998.

    Opis:
    Beach sands from the Rosa Marina locality (Adriatic coast, southern Italy) were analysed mainly microscopically in order to trace the source areas of their lithoclastic and bioclastic components. The main cropping out sedimentary units were also studied with the objective to identify the potential source areas of lithoclasts. This allowed to establish how the various rock units contribute to the formation of beach sands. The analysis of the bioclastic components allows to estimate the actual role of organisms regarding the supply of this material to the beach. Identification of taxa that are present in the beach sands as shell fragments or other remains was carried out at the genus or family level. Ecological investigation of the same beach and the recognition of sub-environments (mainly distinguished on the basis of the nature of the substrate and of the water depth) was the key topic that allowed to establish the actual source areas of bioclasts in the Rosa Marina beach sands. The sedimentological analysis (including a physical study of the beach and the calculation of some statistical parameters concerning the grain-size curves) shows that the Rosa Marina beach is nowadays subject to erosion.
