Opis:
Water exchange between the deep basins of the Baltic Sea during stagnation periods ventilates the bottom layer. Such exchange may be local and associated with the seabed topography features. The aim of this study is to investigate the possible pathway of water exchange within the Gdansk-Gotland ´ Sill. A comprehensive study was conducted near the one of the local erosional trenches (depressions), comprising bathymetric survey using multibeam echosounder, water column CTD-sounding, tilt current meters mooring, and sampling of seabed deposits and macrozoobenthos. The absence of pelitic sediments even in the natural trench depressions was identified. The seabed is composed of dense clays with surface erosion signs. The presence of a current towards the Gotland Basin was recorded in the bottom layer of the erosional trench. This layer was characterized by increased salinity and dissolved oxygen concentration. The trench was also an area with macrozoobenthos richer in species composition and biomass. Moreover, indicator species of the North Sea waters were found exclusively within the erosional trench. Macrozoobenthic community structure and the age of benthic organisms confirm the existence of permanent water exchange directly from the Słupsk Furrow through the erosional trench, and indicate one of the advective pathways of water exchange between the deep Baltic Sea basins.

Concentrations of metals, i.e. As, Cd, Cu, Mn, Ni, Pb, Zn were analysed in bottom deposits of a marine port in Ustka and within the adjacent beach sections. Metal concentrations within the port channel may be ordered in terms of increasing values as: Cd < As < Ni < Zn < Cu < Pb < Mn. Heavy metal concentrations detected in port sediments were much higher than those in beach deposits. Samples of surface waters were also collected from the port channel, harbour basins and nearby beaches and selected physico-chemical indexes were determined, including heavy metal concentrations.
Wykonano analizy stężenia metali As, Cd, Cu, Mn, Ni, Pb, Zn w osadach dennych portu morskiego w Ustce oraz w sąsiadujących odcinkach plaży. Stężenia metali w obszarze kanału portowego tworzyły stężeniowy szereg rosnący: Cd < As < Ni < Zn < Cu < Pb < Mn. Uzyskane stężenia metali ciężkich w osadach portowych były znacznie wyższe niż w osadach plażowych. Z kanału portowego, basenów portowych oraz w pobliżu plaż pobrano również próbki wody powierzchniowej, w których przeanalizowano stężenie wybranych parametrów fizykochemicznych, w tym metali ciężkich.

Opis:
Using the results of the Rossby Centre Ocean model (RCO) the Baltic inflows in summer/autumn 2002 and January 2003 have been studied. The model results were extracted from a long simulation with observed atmospheric forcing starting in May 1980. In RCO a bottom boundary layer model was embedded. Both the smaller inflows and the major inflow in January 2003 are simulated in good agreement with observations. We found that a total of 222 km3 water entered the Baltic in January; the salinity of 94 km3 was greater than 17 PSU. In August/September 2002 the outflow through the Sound and inflow across the Darss Sill were simulated. The net inflow volume amounted to about 50 km3.

Opis:
The paper presents the results of investigations concerning the number, distribution and physiological activity of sulphate-reducing bacteria (SRB) inhabiting the bottom sediments of the Gulf of Gdańsk. The numbers of this group of bacteria range between 0.76 × 103 and 1.27 × 104 cells per g wet sediment. The bacterial sulphate reduction rate in bottom sediments of this area of the Baltic Sea varies from 1.89 to 31.6 nM SO2− 4 g−1 24 h−1. The numbers of SRB and their physiological activity were subject to considerable seasonal fluctuations, maximum values being noted in summer (June) and minima in spring (April). A direct relationship has been found between the number of SRB and hydrogen sulphide concentrations; there is, however, no such relationship with reference to sulphate concentrations. The numbers and distributions of SRB demonstrated considerable variation in a depth profile of bottom sediments. SRB inhabiting the bottom sediments of the Gulf of Gdańsk were able to use three different organic substrates (lactate, acetate, propionate) as electron donors and as carbon and energy sources.

Opis:
Based on various cartographic sources, a digital terrain model and acoustic profiling data, linear relief features of glacial origin have been distin guished and analysed in the Gulf of Riga and adjacent mainland areas in order to reconstruct the dynamics and pathways of former ice streams. North-east–south-west oriented features in the till topography prevail in the central part of the gulf and along the southern coast of the island of Saaremaa, which corroborate the previously known south/south-east di rection of the main Riga ice stream. North-east to south-west directed features dominate in the Pärnu Bay and around the Irbe Strait. Similar deviations from the Riga ice stream are most likely due to ice divide zones, namely the Sakala Upland in Southern Estonia and Kurzeme in north western Latvia, which locally changed the course of the main ice flow. The influence of the Kurzeme ice divide is traceable at the bottom of the gulf up to the southern coast of Saaremaa. There is no evidence of an ice-marginal zone cross ing the central part of the Gulf of Riga as was supposed earlier. The Pandivere-Neva and Palivere ice-marginal zones, which merge on the Sorve Peninsula, probably continue offshore into the Irbe Strait. As the age of the glacier relieffeatures is poorly contained, the chronologi reconstruction of the ice dynamics is tentative.

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.

Opis:
The study covered the aquatic environment of two small rivers in Western Pomerania, Poland, such as the Czerwona and the Grabowa. Its purpose was to determine aluminium bioaccumulation in the aquatic environment by testing water, bottom sediments and aquatic plants. Samples were taken in the summers of 2008-2011. pH, electrolytic conductivity and aluminium concentration were determined in water samples, while the sediment and plant samples were submitted to analyses of the aluminium content. The water pH oscillated between 6.04 and 8.95, while the electrolytic conductivity ranged from 440 to 1598 μS cm-1. The aluminium concentration in the river water was up to 0.138 mg Al dm-3 in the Czerwona and up to 0.425 mg Al dm-3 in the Grabowa. The maximum aluminium content in the bottom sediments was 47.01 mg Al kg-1 in the Czerwona River and 26.15 mg Al kg-1 in the Grabowa River. The maximum aluminium content in the aquatic plants sampled from the Czerwona was 91.63 mg Al kg-1, and from the Grabowa – 1,077 mg Al kg-1. The bioconcentration factor (BCF) of aluminium for the Czerwona River ranged from 5.06 to 24,052, and for the Grabowa River – from 1.10 to 70,132. The concentration factor (CF) of aluminium in the bottom sediments oscillated between 66.72 and 23,492 in the Czerwona River and between 14.81 and 2,763 in the Grabowa. The aluminium content in the two rivers was relatively low in the water, sediments and aquatic plants, which is typical of environments without strong anthropopressure. The values fell within the limits set by environmental water quality standards. The low aluminium accumulation degrees in the biotic and abiotic components indicate that the environments of the two rivers have a low load of aluminium compounds.

Opis:
The world-wide research on ship-aided dispersal of marine organisms and invasions of non-indigenous species focuses primarily on the plankters, which show the greatest potential for invading new areas and establishing viable populations in them, either in the water column (holoplankton) or on the bottom (meroplanktonic larvae of benthic species settling on the sea floor). As meiobenthic animals usually lack a pelagic larval stage in their life cycle, no biological invasion study has, to our knowledge, ever specifically targeted marine transport as a means of meiofaunal dispersal. Here we present a set of data showing that the sediment deposited in a ship’s ballast water tank does support a viable meiobenthic assemblage. We examined 0.015-dm3 aliquots of a 1 dm3 sample from a c. 1.5-cm thick layer of sediment residue in the ballast tank of MS Donnington, brought to the ‘Gryfia’ Repair Shipyard in Szczecin (Poland). The samples were found to contain representatives of calcareous Foraminifera, hydrozoans, nematodes, turbellarians, harpacticoid copepods and their nauplii, and cladocerans, as well as meiobenthic-sized bivalves and gastropods. Nematodes proved to be the most constant and most numerous component of the assemblage. The sediment portions examined revealed the presence of 1–11 individuals representing 11 marine nematode genera. The viability of the meiobenthic assemblage was evidenced by the presence of ovigerous females of both nematodes and harpacticoids. Survival of the meiobenthos in shipborne ballast tank sediment residues may provide at least a partial explanation for the cosmopolitan distribution of meiobenthic taxa and may underlie the successful colonisation of new habitats by invasive meiofaunal species.

Opis:
Integrated investigations of the Lithuanian coast of the Baltic Sea were carried out in 1999-2004 in order to satisfy an increased demand for information about the shoreline. The area of investigations included the beach and the protective dune or cliff (i.e. an onshore belt 100-300 mwide) and reached 15-20 misobaths in the offshore region. This study has resulted in the Geological Atlas of the Lithuanian coast of the Baltic Sea, which consists of digital maps including a geological-geomorphological map, a map of anthropogenic load at a scale of 1:5000 and an explanatory note. Data arrays from shoreline geodynamic monitoring and from field and analytical studies as well as descriptions of borehole sections are provided in graphic and textual annexes. On basis of these investigations 92 morpholithological profiles of the offshore zone and 101 geological cross-sections of the onshore zone were prepared. The basic geological information in the form of maps and special data arrays allows assessment of the current geological condition of the Baltic Sea shores and enables forecasts for their development. It also can be used for environmental protection and land use in the shoreline area: prevention of erosion, designing of protected, recreation and urban areas, as well as substantiation and development of a seashore monitoring system.

Opis:
A population of Cerastoderma glaucum Poiret 1789 was studied in the Polish coastal zone (up to 3 Nautical miles) of the Baltic Sea within the Puck Bay and part of the Gulf of Gdańsk. The frequency (F) in the sheltered coastal zone of bays was high (65%), whereas at the exposed open coast of the Middle Pomerania it was lower (43%). Also, abundance in the Puck Bay and the Gulf of Gdańsk was over 3-fold higher than in the coastal zone of the Middle Pomerania. By means of classic statistical methods (essential tests) we proved the significance of differences between mean abundance at west and east transects in estuaries and between open coast and estuaries. The multivariate regression and classification trees (MR&CT) indicated that biomass and abundance of C. glaucum in the Baltic Sea were affected by the kind of bottom, whereas depth and distance to the bank influenced cockles' abundance and biomass in bays. The population's structure in the Puck Bay and the Gulf of Gdańsk was determined mainly by the depth. In the Wieprza River estuary only specimens from age group 1+ were found. On all the other studied profiles cockles lived up to 3 or 4 years and the dominant group was 2+. The highest mean width of shell was in the Słupia River estuary, and in the bays shell width increased from west to east. In comparison to the other bivalves inhabiting the discussed area, C. glaucum does not play an important role as food source for fish and other consumers but may serve as an indicator of environmental conditions.
Badano populację małża sercówki bałtyckiej Cerastoderma glaucum (Poiret, 1789) w polskiej strefie przybrzeżnej Bałtyku (do 3 Mm), oraz w Zatoce Puckiej i Zatoczce Gdyńskiej (część Zatoki Gdańskiej). Frekwencja dla strefy przybrzeżnej zatok była wysoka i wynosiła średnio F = 65%, a dla strefy przybrzeżnej Wybrzeża Środkowego tylko F = 43%. W strefie przybrzeżnej Zatoki Puckiej i Gdyńskiej zagęszczenie Cerastoderma było ponad 3-krotnie wyższe w porównaniu do masy mokrej w strefie przybrzeżnej Wybrzeża Środkowego. Przy użyciu klasycznych metod statystycznych (testów istotności) wykazano różnice w średnim zagęszczeniu pomiędzy profilami wschodnimi i zachodnimi w estuariach oraz pomiędzy otwartym wybrzeżem a strefami estuariowymi. Zastosowana metoda MR&CT (drzewa regresyjne) dla danych z Morza Bałtyckiego wskazała, że na biomasę i zagęszczenie Cerastoderma wpływ ma jedynie granulacja podłoża, natomiast na obszarze zatok na zagęszczenie wpływa głębokość, a na biomasę odległość od brzegu. Struktura populacji Cerastoderma glaucum zasiedlającej Zatokę Pucka i Gdańską jest determinowana głównie przez głębokość. Najkrócej sercówki żyły w estuarium Wieprzy, gdzie występowały wyłącznie osobniki z grupy wiekowej 1+. Na pozostałych badanych pod tym względem profilach małże te dożywały wieku 3 i 4 lat, z dominującymi starszymi grupami wiekowymi, głównie 2+. Badania szerokości muszli wykazały, że średnia szerokość muszli badanych Cerastoderma na obszarze Wybrzeża Środkowego była największa w estuarium Słupi, natomiast na obszarze zatok zasadniczo wzrastała z zachodu na wschód. W porównaniu do innych gatunków małży zasiedlających badany obszar, Cerastoderma glaucum, ze względu na niewielką liczebność, nie odgrywa większej roli ekologicznej oraz nie tworzy bogatej bazy pokarmowej dla ryb i innych hydrobiontów, może natomiast posłużyć jako organizm wskaźnikowy niekorzystnych zmian zachodzących w środowisku.
