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:
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:
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 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:
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 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 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:
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.

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.

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.

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.

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.

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.
