Opis:
Knowledge of the hydrodynamic conditions and the exchange of water in estuaries is important for ecological, navigational and water management reasons. The morpho-logy, river flow, sea level and local winds constitute important factors that influence the water currents and rate and extent of the mixing of salt and fresh water. The influence of the morphology changes on flow conditions, on the penetration of salt into the estuary and on the water exchange in the estuaries in this paper are analysed on the example of the Odra Estuary. The morphology of the Odra Estuary, and specially the Świna Strait, has changed immensely since the beginning of the XVIII century. The analyses were performed on the basis of data from in situ measure-ments and results of calculations. For the calculation the three-dimensional model ESTURO was used, because of the complexity of the hydrodynamic regimes and their three-dimensional character. The calculations were performed for the three different hydro-meteorological conditions for each of the five analysed morphological situations of the Odra Estuary. Some results of calculations have been presented.

Opis:
The Odra estuary includes, as its major part, the brackish Szczecin Lagoon. This consists of two parts: the Kleines Haff (located in Germany) and the Wielki Zalew located in Poland. The Lagoon receives the River Odra water supplied from the south; prior to being discharged into the Lagoon, part of the Odra flow passes through Lake Dąbie. In its northern part, the Lagoon connects – via three straits (the Peene, Świna and Dziwna) - with the Pomeranian Bay, a Baltic embayment. Water in the lakes of the River Odra estuary were the subjects of a five-year study (2008-2012). Total alkaline phosphatase activity was determined seven times a year in these environments. The zonal study demonstrated that the top sub littoral layer (1 m) featured the highest alkaline phosphatase activity among all the analyzed zones. A study of seasonal fluctuations showed that a maximum total alkaline phosphatase activity occurred in spring (May) and summer (July, August). Basing on this parameter, no increase in eutrophication process in the River Odra estuary was determined in the course of a 5-year study.

The Chinese mitten crab Eriocheir sinensis Milne-Edwards, 1854 is a newcomer to the Baltic Sea. Previous studies have shown that since the 1940s single large specimens of this species have been caught annually in Polish waters. The invasion of the Chinese mitten crab has been reported from many European countries, including Poland, where it is especially abundant in the Odra Estuary. Of 186 specimens captured in Lake Dąbie in August 1998, 45% were females and 55% males. The carapace width of these crabs varied between 53 and 88 mm and the average wet weight was 169±45.3 g.

Opis:
Various types of utilization, conflicting interests and environmental problems call for coastal water management as part of an integrated coastal zone management. This is especially necessary for the Oder (Odra) estuary at the German/Polish border. The river Oder causes severe, ongoing and large scale eutrophication, which limits the ecological and economic value of its adjacent coastal ecosystems. Simulation models are an important tool with which to tackle these practical problems and support management. We present a general concept of a decision support system with an integration of sub-models. Two types of models for long-term water quality forecasts and scenario simulations, as well as short-term prediction of water pollution are available at present. Spatial human-pathogenic virus transport and decay simulations are used as an example to demonstrate their practical use.

Opis:
Eleven PCB congeners were determined in phytoplankton samples collected from the Odra Estuary at 9 stations in 2001–2002. The PCB concentrations were related to the temperature, turbidity, salinity, oxygen and redox potential of the water as well as to the pigment content in the samples. The results indicate that phytoplankton and the detritus derived from it play a crucial role in the distribution of PCBs, their transfer from the water column to sediments and from the Estuary to the sea. The species composition of the phytoplankton occurring in this area could also be very important as regards the sorption of PCBs.

Opis:
Roztoka Odrzańska is the last section of the Odra River estuary. Both in 1996, and in 1999 concentrations of Zn, Cu, Pb, Cd and Hg in the surface waters of Roztoka Odrzańska were within the limits for I class of purity. Maps of the heavy metal distributions in bottom sediments resemble those of TOC distribution in the < 0.20 mm fraction. Overall, 58.3% of the bottom sediments of Roztoka Odrzańska in 1996, as regards concentrations of Cd, Zn, Pb, Cu and Hg, belonged to class IV of purity; 14.6% belonged to class III; 18.8% belonged to class II and 8.3% to class I at all research stations. The excessive pollution the Roztoka Odrzańska sediments is controlled mainly by Cd and Zn concentrations and, to a much lower degree by Pb. Analyses in 1999 showed similar average concentrations of Cu, Zn and Pb, but less than half the content of cadmium. Concentrations, though, of cobalt (1.8x) and especially mercury (22.7x) were higher than the 1996 average levels. The observed concentrations fall within the concentration limits recorded in 1996 for Cu, Zn, Pb, Cd and Co, but they exceed these limits considerably for Hg.

Opis:
Water and sediment in ships’ ballast tanks provide habitats for various organisms, and thus facilitate alien species introductions. Ballast tank water and sediment of 19 ships docked in the GRYFIA Szczecin Ship Repair Yard (Szczecin, Poland) located in an area connected with the River Odra estuary (Southern Baltic), were sampled in 2009–2011 to find out if the ships could be vectors of species introductions to the estuary, already known for the presence of non-indigenous taxa. This study showed the ballast water of the ships examined to house rotifers, copepods, cladocerans, and bivalve and cirriped larvae – common constituents of zooplankton assemblages in coastal waters. The ballast tank sediment supported meiobenthic foraminiferans, nematodes, harpacticoid copepods, turbellarians, bivalves, polychaetes, and chironomid and cirriped larvae. It is not possible at this stage to judge what meiofaunal taxa constitute an alien component in the estuary biota. Macrobenthos in the ships’ ballast tank sediment examined was represented mainly by nereid polychaetes. Although the unintended “biological cargo” examined proved quite diverse and abundant, it contained few identified alien taxa. It does not seem likely than any of them could pose a threat of a biological invasion in the River Odra estuary. However, numerous species remained unidentified, and therefore assessment of the risk of alien species introduction and invasion contains a large measure of uncertainty. On the other hand, the risk as such remains, since the density of ballast water-borne organisms in all ships exceeded the allowed limits.

Opis:
The entire estuary water is dominated by the discharge of the River Odra into the Szczecin Lagoon. The water body is brackish and the salinity in the central part ranges 0.5 and 2 PSU. The Lagoon has a long eutrophication history; usually, two phytoplankton biomass peaks are observed: Diatoms in spring and blue-green algae in summer. The recent data on zooplankton is limited. Rotifers and Cladocerans supply the bulk of the zooplankton biomass. The ichtiofauna is composed of fresh and brackish water, migratory and marine species. Zooplankton and water samples were collected during 2003–2005. The results suggest that during 10 season’s climate in Odra River estuary, Cladocera were the dominant group, large impact on the density of mesozooplankton were: Daphnia cucullata and Daphnia longispina, Copepoda played a lesser role in the Odra River estuary than Cladocera. Biomass of mesozooplankton from the Lagoon was significantly higher compared with the biomass of mesozooplankton from Odra River estuary, which could be related to a greater inflow of nutrients into the Lagoon and the increased growth of phytoplankton, which forms an excellent first stage food web for herbivorous and carnivorous zooplankton, and fish and consequently cormorants.

Wyszczególniono występujące zagrożenia zanieczyszczeniami ze źródeł komunalnych, przemysłowych oraz ze strony transportu morskiego na torze wodnym Szczecin-Świnoujście. Scharakteryzowano elementy państwowego monitoringu środowiska na Zalewie Szczecińskim prowadzonego we współpracy ze stroną niemiecką. Zobrazowano przepływ danych i informacji z przekazywaniem do światowej bazy danych ONZ-owskiego systemu GEMS WATER Programme. Materiał i metody: Metody syntezy i analizy projektowania systemu Wyniki: Koncepcja usprawnienia ochrony wód z zastosowaniem automatycznej stacji pomiarowo- kontrolnej z transmitowaniem odczytów za pośrednictwem telefonii komórkowej i Internetu. Wniosek: Rozwiązanie pozwoli na znaczące zwiększenie częstości pomiarów, wczesne ostrzeganie (np. przy wycieku ze statku) łatwość sterowania i komunikacji drogą radiową i obniżenie kosztów monitoringu.
Introduction and aim: The project of improving the water monitoring system at Odra estuary was presented. The water contamination risk from urban and industrial sewage sources and possible leakage from shipping transport at fairwater Szczecin-Świnoujście was pointed. The features of Polish state environmental monitoring system on Szczecin Lagoon performed with German cooperation were specified. The informational flows of environmental data and reports with transferring to world database of UNEP GEMS/Water Programme were depicted. Material and methods: Analysis and synthesis during system project developing. Results: The concept of improvement of water quality monitoring system on Szczecin Lagoon in Odra estuary with usage of automatic environmental measurement station was proposed. Conclusion: The solution should supply growth of measurements of water quality parameters and perform early warning function (e.g. during leakage from ship). The radio-wave control and data transmission may determine lower costs of environmental monitoring system.
