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:
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.

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:
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.

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:
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.

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:
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.

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.

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.

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.

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.

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.

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:
Beach litter in Small Island should become a special attention issue in Indonesia. This study was carried out to provide a comprehensive dataset including calculating the quantity of beach macro-litter, determine types and concentration of debris present by materials categories, and examine the actual coast cleanliness using Clean Coast Index (CCI). Total of six beaches along the South and North of Ternate Island in September 2018 and March 2019. All surveys performed based on the guideline NOAA Marine Debris Program. All areas in sampling sites will covering used transect 100 m × 10 m as a sampling unit with two replication transects at every location. All sampled will categorize into seven groups including polymers/plastics, rubber, cloths/fabric, paper/cardboard, processed wood, metals, and glass. Overall, there are 3332 items of beach macro-litter found in all surveyed beaches. Polymers/plastics (2040 items, 61.2%) became the highest number of items, followed by glass (403 items, 12.1%), and metals (296 items, 8.9%). During the survey, the highest number of beach litter found on St.1 (1128 items) while the lowest discovered on St.3 (324 items). The abundance (items/m2) found on all beaches range from 0.04 items/m2 to 0.23 items/m2. Meanwhile, CCI on all beaches in very clean to clean category.

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 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:
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:
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.

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.

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.
