Opis:
This study discusses the occurrence of neoplasia in the Baltic clam Macoma balthica from the Gulf of Gdańsk in recent years and investigates potential relationships between toxic compounds in the environment and the presence of the cancer. The disease was identified at four sampling stations during 1999–2002. Comparison with previous results highlighted the substantial prevalence of the tumour between 1998 and 2002. The prevalence of the cancer was strongly dependent on the sampling location (p < 0.001): it was highest at sampling point H45 (the deepest part of the gulf) and lowest at station PB30 (central part of the gulf). Monthly studies showed a trend towards an increasing prevalence of neoplasia during the warm months. However, over several sampling months no strong statistical correlation between the prevalence of the disease and the sampling time was found. The results of the study suggest that several environmental factors may promote the progress of the cancer in M. balthica from the Gulf of Gdańsk: it is most probably an indirect effect of pollution, although causality cannot be proven at this stage. Seriously polluted and exhibiting a considerable asymmetry of contamination, the ecosystem of the gulf provides an ideal environment for testing potential cause-effect relationships between pollutants and their biological effects.

Opis:
The ProDeMo (Production and Destruction of Organic Matter Model), a 3D coupled hydrodynamic-ecological model, was formulated and applied to the whole Baltic Sea and the subregion of the Gulf of Gdańsk. It describes nutrient cycles (phosphorus, nitrogen, silicon) through the food web with 15 state variables, oxygen conditions and the parameterisation of water-sediment interactions. The present version of the model takes two groups of phytoplankton – diatoms and non-diatoms – as well as zooplankton into consideration. It covers the flow of matter and energy in the sea, including river discharges and atmospheric deposition. Numerical applications are embedded on a 1 NMgri d for the Gulf of Gdańsk and a 5 NMgri d for the Baltic Sea. Since the model results largely concur with observations, the model can be regarded as a reliable tool for analysing the behaviour of the Baltic ecosystem. Some examples of the spatial-temporal variability of the most important biological and chemical parameters are presented. The model results are compared with those of other modelling research in the Baltic Sea. Both the ProDeMo model algorithm and its computing procedures need to be further developed. The next version should therefore enable more phytoplankton groups to be defined, for example cyanobacteria, which are able to take up molecular nitrogen from the atmosphere (nitrogen fixation). Additionally, the sediment phase should be divided into active and non-active layers.

Opis:
Background. Macoma balthica is the major zoobenthic species in the Gulf of Gdańsk. Material. Two (4.2%) of the 48 M. balthica specimens collected in 2002 from the depth of 40 m were found to harbour metacercariae−containing sporocysts of Parvatrema affinis (Jameson et Nicoll, 1913) James, 1964. Results. The paper reports morphoanatomical dimensions of 30 sporocysts and metacercariae. Due to the common occurrence of the intermediate (Macoma balthica) and definitive (anseriform and charadriiform birds) hosts of P. affinis in the Gulf of Gdańsk, the trematodes are regarded as a constant component of the local biocoenose.

Opis:
Baltic blue mussels Mytilus trossulus were collected from the Gulf of Gdańsk (southern Baltic Sea) in order to isolate ferritin from its soft tissues, as well as to purify and characterise this protein. Proteins were isolated from the inner organs of M. trossulus (hepatopancreas, gills and soft tissue residue) by thermal denaturation (70◦C) and acidification (pH 4.5) of the homogenates, followed by ammonium sulphate ((NH4)2SO4) fractionation. The ferritin was then separated by ultracentrifugation (100 000×g, 120 min.). The protein content in the purified homogenates was determined by the Lowry method using bovine serum albumin (BSA) and horse spleen ferritin (HSF) as standards. PAGE-SDS and Western blotting analysis permitted identification of ferritin in the purified preparations. Additionally, the purified homogenates and mussel soft tissue were analysed for their heavy metal contents (especially cadmium and iron) in a Video 11 E atomic absorption spectrophotometer, following wet digestion of the samples (HNO3/HClO4). The electrophoregrams showed that the inner organs of M. trossulus contained ferritin, which, like plant ferritin, is characterised by the presence of subunits in the electrophoregram in the 26.6–28.0 kDa range. The highest ferritin content was recorded in the hepatopancreas, followed by the gills and the soft tissue residue. With regard to the sampling stations, the highest content of ferritin was noted in the animals sampled off Sopot (station D3), and in those collected by a diver off Jastarnia (W1) and Gdynia (W4). Ferritin isolated from the inner organs of mussels collected from these stations also contained the largest quantities of heavy metals (Cd and Fe). Ferritin isolated from the inner organs of mussels collected by a diver from wrecks – sites where the concentrations of iron and other trace metals in the sea water are high – contained higher quantities of heavy metals (Cd and Fe) than the ferritin isolated from the inner organs of mussels collected with the drag. This confirms that ferritin is a protein able to store and transport not only iron, but also, though to a lesser extent, some other heavy metals, including cadmium.

Opis:
The paper presents the results of research into the pigment composition of seawater samples taken from various depths in the Gulf of Gdańsk in April and September 1999. Pigments were separated by RP–HPLC, and identification was confirmed by co-injection with reference standards and on-line diode array spectra. The following groups of pigments were identified: chlorophylls: a, b, c1 + c2; photosynthetic carotenoids (PSC) – peridinin, fucoxanthin, α-carotene; photoprotecting carotenoids (PPC) – diadinoxanthin, alloxanthin, zeaxanthin, lutein, neoxanthin, violaxanthin and β-carotene. Quantitative and qualitative diversity in pigment characteristics were observed in both seasons, though lutein and α-carotene were not identified in the September samples. The respective April and September concentrations of the functional groups of pigments were: total chlorophylls content 0.47–104.25 and 0.57–13.66 μg dm−3; PSC 0.07–21.23 and 0.02–1.56 μg dm−3; PPC 0.05–14.08 and 0.04–1.79 μg dm−3. Within the PSC group, peridinin and fucoxanthin were dominant in the April samples, but only fucoxanthin in the September ones. Among the PPCs, diadinoxanthin and alloxanthin were dominant in April, zeaxanthin in September. Photosynthetic and photoprotecting carotenoids display a linear correlation with chlorophyll a content in all the samples.

Opis:
A three-dimensional baroclinic σ–coordinate model was applied to study the circulation and thermohaline variability in the coastal zone in the south-eastern Baltic Sea. The model is based on the Princeton Ocean Model code of Blumberg & Mellor (1987), known as POM, and has the horizontal resolution of ∼5 km and 24 σ-levels in the vertical. The hydrodynamic conditions and variability of water and salt exchange between the Gulf of Gdańsk and the Baltic Proper, and the renewal of water masses in the Gulf of Gdańsk due to atmospheric forcing are analyzed. The numerical simulations were performed with real atmospheric forcings as well as with homogeneous (spatially uniform) wind fields over the whole Baltic Sea. The numerical simulations showed that the atmospheric forcing (winds) can play a significant role in shaping the renewal of bottom saline waters in the Gulf of Gdańsk. Two regions of inflow/outflow of saline waters responsible for the salinity regime were located. The overall water exchange between the Gulf and the Baltic Proper as well as the exchange of saline bottom waters appear to be strongly dependent on wind conditions. The net flux of water of salinity >9 PSU is of the order of 48 000–100000 m3 s−1. SE, E, S and NE winds were found to exert the greatest influence on salinity conditions in the Gulf of Gdańsk. Estimates of saline (salinity >9 PSU) water residence time based on the model simulation yielded values from 46 days for SE winds to 153 days for NW winds.

Opis:
The round goby (Neogobius melanostomus) is a non-indigenous species in the Baltic Sea, introduced to its waters (the Gulf of Gdańsk) from the Black, Azov, and Caspian Seas. For this reason, an attempt was made to determine the species' parasitic fauna in its new environment. Within 1994-2000, a total of 201 round goby specimens caught in the Gulf of Gdańsk were examined. The parasites found represented protozoans (Trichodina domerguei domerguei), digencans (Diplostomum spp. metacercariae), cestodes (Bothriocephalus scorpii, plerocercoids), nematodes (Hysterothylacium aduncum L₃, L₄, and adults), and canthocephalans (Echinorhynchus gadi and Pomphorhynchus laevis). The parasitic species found are common in the Gulf of Gdańsk. It should be emphasized that, since the round goby has only recently appeared in the Gulf, the parasitic fauna of this fish is not yet complete.

The AChE activities [nmol min−1 mg protein−1] were in the range: 15–38 (in blue mussels) and 94–315 (in flounder), and agreed well with those reported for flounder in other coastal Baltic areas, and other European seas. Sources of contaminants in the study area are rather localized in the Gulf of Gdańsk, (mouth of the Vistula due to runoff, ports, sewage discharges), while an accidental oil spill occurred off Lithuania, in the course of the study (November 2001). Geographical and temporal AChE levels changes followed the contamination pattern. AChE activities and gradients in the study area are well documented and confirmed in this study. The study confirms the potential use of AChE as biomarker of organic pollution.

Opis:
This paper describes the seasonal and spatial variations of diffusive sediment– water ammonium fluxes in the western part of the Gulf of Gdańsk (southern Baltic). It assesses the potential environmental controls of these fluxes, such as the inflow of organic matter to bottom sediments and its quality, temperature-induced degradation of organic matter, and the redox potential of sediments. Ammonium fluxes, calculated using Fick’s first law, were always in the direction from the sediment into the water column and differed significantly with respect to sediment type. Fluxes were most intensive in sediments with the highest silt-clay fraction located in the deepest parts of the study area. The mean annual diffusive fluxes of ammonium from sediments to near-bottom water were estimated at 5.24 tonnes km−2 year−1 for silty-clays, 1.85 tonnes km−2 year−1 for silty-sands and 1.03 tonnes km−2 year−1 for sandy sediments. There was a high seasonal variation, with the greatest ammonium release in summer and early autumn, when the temperature of near-bottom water was the highest. On the basis of the calculated diffusive ammonium fluxes, we estimated that approximately 2700 tonnes of N–NH+4 are released annually from the surface sediments of the western part of the Gulf of Gdańsk, providing a minimum of 10% of the mineral nitrogen essential for primary production in surface waters. Our results are undoubtedly underestimated, as we disregarded advective ammonium fluxes, which in some areas of the Gulf of Gdańsk could well be comparable to diffusive fluxes.

Opis:
An ecohydrodynamic model was used to investigate the effect of the Hel upwelling on nutrient concentrations, primary production and phytoplankton biomass. The model covered the whole Baltic Sea with a 5 NM grid spacing and the Gulf of Gdańskwith a 1 NM grid spacing. Validation indicated good agreement between model results and measurements in the GdańskD eep, and slightly weaker concord for the Hel upwelling area. The vertical nutrient fluxes associated with up- and downwelling in the Hel region were simulated for two 30-day periods in 2000. The nutrient input resulting from long-term upwelling is comparable to the load carried into the Gulf of Gdańskb y the Vistula (Wisła), the largest river in the vicinity. Performed at times when upwelling was almost permanent, the simulations showed elevated nutrient concentrations in surface waters. This was especially distinct in spring when primary production and phytoplankton biomass were both higher. In late summer, however, upwelling caused primary production to decrease, despite the elevated nutrient levels.

Opis:
The photosynthetic quotient (PQ) is defined as the molar ratio of oxygen released to the carbon dioxide assimilated during photosynthesis. Calculation of correct PQ values of natural phytoplankton populations is crucial for understanding of carbon budgets but often result in values that differ highly from the expected stoichiometric proportions of photosynthetic products. In the present study, measurements of primary production, that is, CO2 assimilation, performed with the standard isotopic method (14C) and oxygen release estimated during photosynthesis with the light-and-dark bottle method were compared to calculate PQ in the southern Baltic (Gulf of Gdańsk, Poland). The PQ average was 1.28 (ANOVA; F = 872; R2 = 0.92; n = 77; p < 0.001). Neither nitrogen source nor phytoplankton composition was noted to impact PQ values. Very high PQ values in the lower range of production rates (that cannot be explained by the stoichiometric proportion of photosynthesis products) were interpreted as artifacts related to the lower sensitivity of the oxygen method compared to that of the 14C method.
Współczynnik fotosyntetyczny (PQ) definiowany jest jako molowy stosunek uwolnionego tlenu do węgla związanego w procesie fotosyntezy. Obliczenie poprawnej wartości PQ dla populacji fitoplanktonu występujących w środowisku jest zasadnicze dla sporządzenia poprawnego bilansu węgla, ale często obliczone z pomiarów wartości PQ różnią się znacznie od proporcji stechiometrycznych tlenu i węgla w produktach fotosyntezy. W niniejszej pracy przeprowadzono pomiary asymilacji węgla, czyli produkcji pierwotnej, przy użyciu standardowej metody izotopowej (z izotopem węgla 14C) oraz pomiary uwolnionego tlenu za pomocą metody jasnych i ciemnych butelek i na tej podstawie obliczono współczynnik fotosyntetyczny dla Bałtyku południowego (Zatoka Gdańska, Polska). Obliczona średnia wartość PQ wynosiła 1,28 (ANOVA; F = 872; R2 = 0,92; n = 77; p < 0,001). Nie odnotowano, aby wartości PQ zależały od rodzaju azotu wykorzystanego w procesie asymilacji (azot azotanowy czy amonowy) lub od składu fitoplanktonu. Bardzo wysokie wartości PQ obliczone w zakresie niskich wartości produkcji pierwotnej (wartości, które nie zgadzają się zupełnie z proporcjami stechiometrycznymi produktów fotosyntezy) zostały zinterpretowane jako artefakty wynikające z metodyki pomiarowej, ponieważ metoda tlenowa ma znacznie mniejszą czułość niż metoda izotopowa.
