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:
Anguillicola crassus is an Asian nematode, dwelling in eel swim bladder and accidentally introduced to Europe. The eel becomes infected by consuming either crustaceans (intermediate hosts) or small fish (paratenic hosts), supporting stage 3 larvae. In 2002, 15 specimens of dab (Limanda limanda) caught in the Gulf of Gdańsk and 8 caught in the Vistula Lagoon were examined for the presence of A. crassus larvae. Two Gulf of Gdańsk specimens and one Vistula Lagoon fish were found to host 4 stage 3 larvae of A. crassus. This is the first world's record of A. crassus in the dab. It is suggested that, due to a large size of the infected fish, they cannot function as paratenic hosts in the A. crassus life cycle.

The hydrological conditions, suspended matter concentrations and vertical par- ticulate matter flux were measured as the River Vistula flood wave (maximum discharge) was flowing into the southern part of the Gulf of Gdańsk on 26 May 2010. Extending offshore for several tens of kilometres, the river plume was well stratified, with the upper layer flowing away from the shore and the near-bottom water coastwards.

Opis:
The great cormorant Phalacrocorax carbo sinensis (Blumenbach, 1798) is one of the most important birds in the Vistula Lagoon and the Gulf of Gdańsk area. As a typical piscivore the bird plays a significant part in life cycles of parasites in aquatic ecosystems. Within January 2000-June 2001, a complete helminthological examination was performed on great cormorants collected in the nesting area at Kąty Rybackie on the Vistula Spit (80 specimens) and in the Vistula Lagoon (10 specimens). The infection prevalence mean intensity, and intensity range were 92.2%, 376.5, and 1-4524, respectively. The presence of 9 digenean species (Paryphostomum radiatum (Dujardin, 1845), Petasiger exaeretits Dietz, 1909, P. phalacroracis (Yamaguti, 1939), Mesorchis pseudoechinatus (Olsson, 1876), Metorchis xanthosomus (Creplin, 1846), Cryptocotyle concavum (Creplin, 1825), Hysteromorpha triloba (Rudolphi, 1819), Tylodelphys clavata (Nordmann, 1832), and Holostephanus dubinini Vojtek et Vojtkova, 1968) was recorded, P. phalacrocoracis being the most common parasile (prevalence 92.2%, mean intensity 323.8). Tylodelphys clavata proved a parasite new for the great cormorant moreover the records of P. phalacrocoracis, H. triloba, and H. dubinini are the first in Poland, while C. concavinn and M. pseudoechinatus were for the first time recorded in the great cormorant in Poland.

Opis:
The Vistula Lagoon is situated along the south-eastern shore of the Gulf of Gdańsk and is linked with the gulf through the Strait of Baltiysk. Separated from the open sea by the Vistula Spit, the Vistula Lagoon is a shallow body of water with a mean depth of 3 m; the bottom is covered with a layer of mud several metres thick. This article presents a unique, newly discovered locality of tree stumps occurring in situ at the bottom of the Vistula Lagoon. The radiocarbon age of the alder stumps and the top of the peat in which they are rooted is Subboreal. The alder wood was dated to 4770±35 and 3295±35 years BP. The top layers of peat were dated to 4670±40, 4410±35 and 3690±35 years BP. The considerable scatter of the dates indicates the significance of erosional processes during marine transgressions. Radiocarbon dates and pollen analyses indicate that in the late Atlantic – early Subboreal periods, the water level of the Vistula Lagoon was about 3 m lower than it is today. The −2 m level was passed no earlier than c. 3500 years ago; the −1 m level was reached around 2000 years ago.

Nine - spined stickleback was noted as a new host in Polish coastal water for five parasites: Glugea anomala (Microsporidia), Diplostomum spathaceum (Digenea – metacercariae) and Apatemon sp. (Digenea - incysted metacercariae), Hysterothylacium aduncum (Nematoda - third stage larvae) and Thersitina gasterostci (Copepoda). Earlier in this area have been obserwed only ciliates Tnchodina domerguei.

Opis:
The aim of this paper is to determine the current biological state of life in the pelagic zone of the Gulf of Gdańsk in relation to the planned start-up of an underwater outfall which will discharge sewage from the Gdańsk–Wschód (Gdańsk–East) sewage treatment plant. The plankton material was collected during two research cruises in July and October 1998. The samples were taken at 15 stations in four profiles located near Wyspa Sobieszewska (Sobieszewo Island), perpendicular to the coastline. Both the taxonomic and numerical structure of phytoplankton and zooplankton were typical of the coastal area of the Gulf of Gdańsk. The species diversity depends on hydrological conditions, mainly input from the River Wisła (Vistula). The abundance and biomass of phytoplankton in 1998 were several times lower than in 1994 and 1995 in the area off Górki Wschodnie, the profile located closest to the planned construction site. This could have been caused by generally lower temperatures in 1998 in comparison to previous years. In the investigated area only traces of algal eutrophication indicator species were noted. However, potentially toxic species were confirmed and were most abundant near the Wisła mouth. The highest concentrations of pelagic fauna occur in the shallowest area closest to the shoreline. Long-term observations of the dynamics of the variations in abundance and species composition indicate the increasing significance of one particular species – Acartia bifilosa.

Opis:
An extensive bio-optical data set obtained from field measurements was used to evaluate the performance of an empirical (Kowalczuk et al. 2005) and two semi- analytical algorithms: Carder et al. (1999) and GSM01 (Maritorena et al. 2002) for estimating CDOM absorption in the Baltic Sea. The data set includes coincident measurements of radiometric quantities and absorption coefficients of CDOM made during 43 cruises between 2000 and 2008. In the first stage of the analysis, the accuracy of the empirical algorithm by Kowalczuk et al. (2005) was assessed using in situ measurements of remote sensing reflectance. Validation results improved when matching points located in Gulf of Gdańsk close to the Vistula River mouth were eliminated from the data set. The calculated errors in the estimation of aCDOM(400) in the first phase of the analysis were Bias = −0.02, RMSE = 0.46 and R2 = 0.70. In the second stage, the empirical algorithm was tested on satellite data from SeaWiFS and MODIS imagery. The satellite data were corrected atmospherically with the MUMM algorithm designed for turbid coastal and inland waters and implemented in the SeaDAS software. The results of the best case scenario for estimating the CDOM absorption coefficient aCDOM(400), based on SeaWiFS data, were Bias = −0.02, RMSE = 0.23 and R2 = 0.40. The validation of the Kowalczuk et al. (2005) empirical algorithm applied to MODIS data led to a less accurate estimate of aCDOM(400): Bias = −0.03, RMSE = 0.19 and R2 = 0.29. This assessment of the accuracy of standard semi-analytical algorithms available in the SeaWiFS and MODIS imagery processing software revealed that both algorithms (GSM 01 and Carder) underestimate CDOM absorption in the Baltic Sea with mean systematic and random errors in excess of 70%. The paper presents examples of the application of the Kowalczuk et al. (2005) empirical algorithm for producing maps of the seasonal distribution of aCDOM(400) in the Baltic Sea between 2004 and 2008.
