Opis:: The paper deals with the conformal mapping of finite, plane, simply connected domains, representing oceans, lakes, estuaries, bays, lagoons, and other natural water bodies of this kind. As a rule, they are bounded by geometrically complex shorelines. The partial differential problems investigated in Oceanology and posed in such domains have turned out to be difficult to solve for at least three reasons. They follow on from the mathematical properties of the differential equations governing such problems, from the just-mentioned geometrical complexity of the domains of solution, and from the sensitivity of the solutions to boundary conditions. In view of the last reason the contours admitted as boundaries of the domains of the solution ought to be as close to the real shorelines as possible. The obviously inaccurate approximation of the shorelines by ‘staircases’, which appears rather often (cf. Catewicz & Jankowski 1983, Lin & Chandler-Wilde 1996) as a consequence of applying finite difference methods to the solution of the partial differential problems, raises serious doubts from the point of view of Numerical Fluid Mechanics. It is recalled in the paper that such inaccuracies are not unavoidable: that complicated plane domains can be transformed accurately by means of properly applied conformal mapping onto regular, canonical domains – in particular, onto discs or squares. Such a transformation is demonstrated on the rather difficult example of the Vistula Lagoon. The transformation begins with the decomposition of the domain into five plane subdomains, each one of which is eventually transformed onto a disc. Every such result is arrived at quite independently of the remaining subdomains, by means of a set of properly selected consecutive mappings. Hence, the final canonical domain consists in this case of a system of five discs which, however, within the framework of this differential problem, have to be treated as interconnected. The interconnections involve images of four segments of straight lines, separating the original subdomains. The transformations and the resulting canonical domain presented in the paper are intended to be applied to the solution of certain hydrodynamical problems concerning the Vistula Lagoon, which will be published elsewhere.

Opis:: The paper presents a lithodynamic interpretation of the Polish-Russian morpholog- ical and lithological research project along the marine coastal zone of the Vistula Spit, carried out between July and September 2008. 78.4% of the coastal zone is characterized by a balanced environment, with fractional transport of sediments as bed and suspended load. Deposition was observed in 8.2% of the study area. A dynamic environment with a deficit of bed material, local turbulences and erosive trends were found in 13.2% of the coastal zone. The critical erosive current velocities vary from 16 to 20–26 cm s−1.

Opis:: This paper analyzes whether physicochemical properties significantly influence the occurrence of zooplankton in a brackish reservoir. The studies were carried out on the Vistula Lagoon in August and September from 2006 to 2009 at 32 research sites. The environmental conditions in the Vistula Lagoon varied widely. At the time of the investigation, 17 species of rotifers, six species of Cladocera, and ten species of Copepoda were noted, and the total density of plankton fauna ranged from 145 to 765 ind. dm3. Statistical analysis demonstrated a significant correlation between the occurrence of some zooplankton species and certain environmental parameters, whereas the sampling sites were grouped according to study years. The zooplankton systems recorded at the research sites in 2006 constitute the most disparate group. Thus, it can be concluded that physicochemical properties might significantly impact both individual species (depending on their environmental demands) and entire zooplankton clusters.

Opis:: The round goby, Neogobius melanostomus (Pallas, 1811) was introduced into southern Baltic waters (including the Vistula Lagoon) from the Black Sea and Sea of Azov in the early 1990s. This study describes the parasites of the round goby in its new environment. In 2004, 486 round goby specimens from the Vistula Lagoon were examined for parasites. The following taxa were identified: Dermocystidium sp.; Protozoa: Trichodina domerguei domerguei (Wallengren, 1897); Digenea: Cryptocotyle concavum (Creplin, 1825), Diplostomum spp., Tylodelphys clavata (Nordmann, 1831), Bunodera luciopercae (M¨uller, 1776); Cestoda: Bothriocephalus scorpii (M¨uller, 1776), Eubothrium crassum (Bloch, 1779), Paradilepis scolecina (Rudolphi, 1819), Proteocephalus filicollis (Rudolphi, 1802), P. gobiorum Dogel et Bychovsky, 1939, Proteocephalus sp.; Nematoda: Anguillicola crassus Kuwahara, Niimi et Itagaki, 1974, Camallanus truncatus (Rudolphi, 1814), Contracaecum spp., Cystidicoloides ephemeridarum (Linstow, 1872), Dichelyne minutus (Rudolphi, 1819), Hysterothylacium aduncum (Rudolphi, 1802); Acanthocephala: Echinorhynchus gadi M¨uller, 1776, Pomphorhynchus laevis (M¨uller, 1776). The parasites found were all local species, already reported from Poland. Except for Dermocystidium sp., C. concavum, P. gobiorum, and D. minutes, they have already been recorded in other fish species in the Vistula Lagoon. The prevalence and mean intensity of infection was low (18.3%; 4.0 indiv. – this value does not include ciliates). The most frequent parasites included H. aduncum (9.9%, 1.2 indiv.) and A. crassus (9.1%, 1.2 indiv.). In addition, Dermocystidium sp., B. luciopercae, E. crassum, P. scolecina, P. filicollis, C. truncatus and C. ephemeridarum are reported from the round goby for the first time. As the fish has only recently appeared in the Vistula Lagoon, its parasitic fauna has not yet developed to the full.

Opis:: This study reports the propagation dynamics of the Kara Sea surface desalinated layer (SDL) during the summer and autumn seasons. We analysed shipboard measurements data collected in 2013–2018 and MODIS ocean colour data that correlated with the shipboard ones. We formulated a comparatively strict criterion to determine the SDL border based on satellite data. For that, we analyzed the shipboard flow-through measuring system data obtained while crossing the surface desalinated layer border. Further, we used a regional algorithm to process the satellite data and estimate the coloured dissolved organic matter absorption coefficient for the Kara Sea. The results demonstrate a significant effect of the wind regime on the interseasonal and interannual variability of the transformation of the SDL boundaries. The positions of the surface desalinated layer boundaries at different times during 2013–2018 are given. The obtained results are important for calculating the heat balance and analyzing the Kara Sea bio-productivity.

Opis:: The paper contains the results of natural film experiments carried out on inland waters in the Dead Vistula (Martwa Wisła) catchment area during 1999–2002 using the integrated Langmuir trough-Wilhelmy plate system,w hich ‘cuts out’ an undisturbed film-covered area without any physicochemical sample processing. The static film parameters result from the generalized scaling procedures applied to the surface pressure-area isotherms. They appear to correspond well to observations of the film composition (Alim, MW, Eisoth),film solubility and the miscibility of its components (via R, ΔSc and y factors),and surface concentration (πeq, Γeq). A novel approach is presented for the adsorption dynamics on the basis of the mixed kinetic-diffusion model and analyses of the dynamic surface pressure plots,whic h leads to the determination of the effective relative diffusion coefficient Deff/D and activation energy barrier Ea/RT . There is reason to believe that certain classes of film-forming components or ‘end-members’ may dominate the static and dynamic surface properties. Some of these substances can be used as source-specific surface-active biomarkers to trace temporal and spatial changes due to environmental factors or the production of biological matter. The concept was tested for the Dead Vistula river and its tributaries. The results demonstrate that natural films are a complex mixture of biopolymeric molecules covering a wide range of solubilities,sur face activities and molecular masses with an apparent structural film architecture. Such studies could lead to the development of film structure parameters – indicators of ecosystem quality and the state of the environment.

Opis:: The paper presents a comparative analysis of two different river mouths from two different geographical zones (subtropical and temperate climatic regions). One is the multi-branch and multi-spit mouth of the Red River on the Gulf of Tonkin (Vietnam), the other is the smaller delta of the river Vistula on a bay of the Baltic Sea (Poland). The analysis focuses on the similarities and differences in the hydrodynamics between these estuaries and the adjacent coastal zones, the features of sediment transport, and the long-term morphodynamics of the river outlets. Salinity and water level are also discussed, the latter also in the context of the anticipated global effect of accelerated sea level rise. The analysis shows that the climatic and environmental conditions associated with geographical zones give rise to fundamental differences in the generation and dynamic evolution of the river mouths.
