Opis:: Submarine groundwater discharge (SGD) is one of the water pathways connecting land and ocean in the global water cycle. Moreover it has been recently recognized as important factor influencing coastal zone [5]. In comparison with easily seen and typically large point sources surface of water inputs (e.g. rivers and streams), which are gauged and well analysed, estimations of groundwater inputs are much more difficult due to lack of simple mean to gauge these fluxes [28]. Groundwater in many areas has become contaminated and therefore is a source of nutrients, trace metals, organic compounds and radionuclides.
Dopływ wód podziemnych do środowiska morskiego jest obecnie postrzegany jako istotny szlak wymiany masy pomiędzy lądem i oceanem. Cechuje go znacząca przestrzenna i czasowa zmienność, w porównaniu do spływu rzecznego, co utrudnia jakościową i ilościową charakterystykę dopływających substancji. Dopływająca woda podziemna i zawarte w niej substancje (związki organiczne, substancje biogeniczne czy metale) wpływają w szczególności na przemiany geochemiczne w wodach przybrzeżnych. Badania dotyczące dopływu wód podziemnych do środowiska morskiego są prowadzone na świecie, w tym na Morzu Bałtyckim od wielu lat. Podjęto też badania dotyczące dopływu wody podziemnej - wody wysiękowej do Zatoki Gdańskiej. Próbki wody są pobierane za pomocą batometrów, kolektorów wody wysiękowej i piezometrów, a następnie analizowane. Ustalono że, wody wysiękowe zawierają substancje biogeniczne, rozpuszczony węgiel nieorganiczny oraz metale śladowe w szerokich zakresach stężeń. Otrzymane wyniki stężeń badanych komponentów wody korelują z zasoleniem i pH. Dalsze badanie zjawiska dopływu wód wysiękowych i ich charakterystyki jest niezbędne dla lepszego zrozumienia zasad funkcjonowania ekosystemów morskich oraz określenia niebezpieczeństw zagrażającym im, związanych z dopływem dużych ilości substancji toksycznych.

Opis:: Sediment cores collected in several areas of the southern Baltic were analysed for total mercury (HgTOT) and five operationally defined mercury fractions: HgA – contained in pore waters, HgF – bound to fulvic acids, HgH – bound to humic acids, HgS – bound to sulphide, and HgR – residual. An effort was made to quantify mercury fluxes at the sediment/water interface in the study area. Net mercury input, calculated on the basis of sedimentation rate and concentration in the uppermost sediments, ranged from 1 to 5.5 ng cm−2 year−1. Mercury remobilisation from sediments due to diffusion and resuspension was calculated from the proportion of labile mercury and the velocity of near-bottom currents. The results showed that the return soluble and particulate fluxes of mercury from the sediments to the water column constitute a substantial proportion of the input (20–50%), and are slightly higher than those found in pristine areas, although they are less than the values recorded in areas with a history of mercury contamination. In addition, an index was developed to assess the methylation potential of mercury in sediments. Mercury contained in pore waters, and mercury bound to fulvic and humic acids together with Loss on Ignition were used to calculate the semiquantitative methylation potential (Pm). Despite the simplicity of this approach, Pm correlates well with methyl mercury in fish from the study area.

Opis:: Fluffy Layer Suspended Matter (FLSM) is a layer of fairly concentrated suspended matter resting on the sea floor. Its passage to the depositional basins in the Pomeranian Bay – Arkona Deep System of the Baltic Sea is estimated to take around six months. In the course of this migration, the properties of FLSM change as a result of ageing and the influx of fresh particles from the water column, and possibly also because of mass exchange with the uppermost sediment layers. Measurements of radioisotopes (210Po, 210Pb, 137Cs) have demonstrated that in shallow water this topmost layer of sediments, from 8 cm to 3 cm in thickness, is subject to mixing. This creates redox profiles favourable to biota and bioturbation. Basing on 210Pb/210Po disequilibria and the 210Po excess, it was estimated that under steady state conditions from 1.5 to 2.2% of fine fraction (FSF) in the mixed layer of sediments is freshly imported from FLSM. This implies replacement of FSF from the sediments and its incorporation into FLSM. On the assumption that the surface density of FLSM is 10 mg cm−2, FSF freshly exported from sediments actually comprises up to 15% of FLSM. Therefore, the properties of FLSM are strongly influenced by the processes taking place in the sediments, although FLSM by definition is independent of sediments.

Opis:: Lignin oxidation products (vanillyl, syringil and cummaryl phenols), and δ13C were measured in a variety of land and marine samples collected in Inner Puck Bay – dominated by marine vascular plants, small river run-off, and shallow bottom, and in Gdańsk Bay – characterized by large river run-off, small marine vascular plants population, and the average depth exceeding euphotic zone. Both study areas are parts of the Gdańsk Basin, Southern Baltic. Typical δ13C values (δ13C = -28‰) and both composition and concentrations of lignin phenols were measured in samples originating from land. Small, yet easily measurable amounts of lignin phenols were found in marine vascular plants biomass (Σ8 = 90 µg/100 mg organic matter). The biomass was characterized by exceptionally high δ13C values (-12‰). No lignin phenols and typical δ13C values (-22‰) were measured in marine phytoplankton biomass. δ13C and both composition and content of lignin phenols in organic matter of surface sediments collected in the study area fall in the range marked by the end members. The proportion of land derived organic matter calculated using lignin phenols, or δ13C in Gdańsk Bay were comparable, while in Puck Bay they differed substantially. It was concluded that a) in areas with substantial bottom coverage with vascular plants the two end members approach, usually employed to establish the contribution of organic matter sources, is insufficient, b) organic matter originating from three sources: riverine, phytoplankton, and vascular plants contribute to sedimentary organic matter in Puck Bay with the respective proportion 30:40:30.

Opis:: Fluffy layer suspended matter (FLSM) and surface sediment samples from the Pomeranian Bay were examined for fatty acid, lipid and organic matter contents. FLSM is a several-centimetre-thick layer of fairly concentrated particulate matter lying on the sea floor significantly affecting the flux of matter to depositional basins. Analyses of fatty acids were used to establish sources and decomposition rates of labile organic matter along a transect from the shallow, highly dynamic, Odra estuary to the Arkona Basin, a deep, low energy, depositional area. In FLSM and sediments respectively, the ranges of organic matter contents were 4.0–25.0% and 5.1–23.0%, those of lipids 0.1–5.4% and 0.30–1.67%, and those of fatty acids 50–991 μg g−1 dry wt. and 100–546 μg g−1 dry wt. In shallow waters, the contents of these compounds are very variable, mirroring variations in biological activity and hydrological conditions. The high percentage of polyunsaturated fatty acids in shallow areas indicates the presence of fresh, undegraded, labile organic matter of autochthonous origin. Fatty acids, the most labile components, are transported as suspended matter attached to minerals and finally accumulated in the depositional area in the form of condensed organic macromolecules. The intensity of bacterial decomposition of organic matter in this system is reflected in the high percentage of branched fatty acids. The low fatty acid content in the organic matter is attributed to the high rate of decomposition of the labile organic matter. No linear correlation was found between the contents of fatty acids and lipids.

Opis:: This paper presents a zero-dimensional particulate detritus model (Figure 1) and a comprehensive description of parameterisation processes that influence the non-living organic matter (detritus) concentration in the whole water column. Mathematically, the particulate pelagic detritus concentration can be described as a variable dependent on the number of its sources and sinks. Temporal supplies in the pelagic detritus concentration are affected by the natural mortality of phytoplankton and zooplankton as well as by the faecal pellets that enter the detritus pool. On the other hand, sedimentation, grazing of detritus by zooplankton and mineralization of pelagic detritus act as sinks that reduce the detritus concentration in the water column. The aim of this model study was to calibrate the detritus model under the environmental conditions typical of the Gdańsk Deep in the southern Baltic Sea.
Przedmiotem badań jest parametryzacja zero wymiarowego Modelu Detrytusu Pelagicznego (PDM). Stężenie detrytusu pelagicznego w wodzie morskiej jest determinowane równowagą ustaloną pomiędzy źródłami i ubytkami martwej, zawieszonej materii organicznej. Do źródeł zalicza się: śmiertelność fito- i zooplanktonu oraz odchody zooplanktonu. Wśród ubytków detrytusu wyróżnić można natomiast sedymentację, wyżeranie przez zooplankton oraz rozkład biochemiczny. Przedstawione badania opisują oddziaływanie temperatury, stężenia związków biogenicznych, nasłonecznienia oraz biomasy fito- i zooplanktonu na stężenie detrytusu pelagicznego w wodzie morskiej. Parametryzacja przeprowadzona została w typowych dla południowego rejonu Morza Bałtyckiego zakresach zmiennych. Detrytus pelagiczny razem z fito- i zooplanktonem są komponentami niezbędnymi do opisania zmienności stężeń zawieszonego węgla organicznego (POC) będącego istotnym składnikiem obiegu węgla w środowisku morskim. Prawidłowa parametryzacja PDM stanowi zatem podstawę dla numerycznego opisu aktualnej i przyszłej zmienności stężeń POC w wodzie Morza Bałtyckiego.

Opis:: AChE activities were measured in blue mussels gills and flounder muscles samples collected off Poland – the Gulf of Gdańsk (4 sampling stations) and off Lithuania – the Klajp˙eda area (3 sampling stations), in 2001 (June and October) and 2002 (April and October). 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 discusses predictions of particulate organic carbon (POC) concentra- tions in the southern Baltic Sea. The study is based on the one-dimensional Particulate Organic Carbon Model (1D POC), described in detail by Dzierzbicka- Głowacka et al. (2010a). The POC concentration is determined as the sum of phytoplankton, zoo- plankton and dead organic matter (detritus) concentrations. Temporal changes in the phytoplankton biomass are caused by primary production, mortality, grazing by zooplankton and sinking. The zooplankton biomass is affected by ingestion, excretion, faecal production, mortality and carnivorous grazing. The changes in the pelagic detritus concentration are determined by the input of dead phytoplankton and zooplankton, the natural mortality of predators, faecal pellets, and sinks – sedimentation, zooplankton grazing and biochemical decomposition. The model simulations were done for selected locations in the southern Baltic Sea (Gdańsk Deep, Bornholm Deep and Gotland Deep) under predicted conditions characterized by changes of temperature, nutrient concentrations and light availability. The results cover the daily, monthly, seasonal and annual POC concentration patterns in the upper water layer. If the assumed trends in light, nutrients and temperature in the southern Baltic correctly predict the conditions in 2050, our calculations indicate that we can expect a two- to three-fold increase in POC concentration in late spring and a shift towards postponed maximum POC concentration. It can also be anticipated that, as a result of the increase in POC, oxygenation of the water layer beneath the halocline will decrease, while the supply of food to organisms at higher trophic levels will increase.

Opis:: The aim of this study was to identify and quantify lignin transported from the River Vistula to the accumulation area in the Gdańsk Basin. Sediment samples collected along the Vistula mouth –Gdańsk Deep transect were analysed for lignin. Lignin was characterised by oxidative degradation, cupric oxide being chosen as the most suitable oxidising agent. The polar functional groups of the oxidation products were silylated and the derivatives analysed by capillary gas chromatography on fused capillary silica columns with flame ionisation detection. Lignin-derived oxidation products were quantified in the range from 3 to 20 μg g−1 dry wt. for phenolic acids and from 6 to 12 μg g−1 dry wt. for phenolic aldehydes. Differences in oxidation products contents are assigned to different lignin sources in the marine environment. The horizontal and vertical gradients of these compounds in the sediments of the Gdańsk Basin are documented. The results are discussed in terms of the origin and fate of organic matter in the Gdańsk Basin. The measured differences in quality and quantity of the identified oxidation products provide insight into diagenetic processes in the surface marine sediments.

Opis:: Particulate Organic Carbon (POC) is an important component in the carbon cycle of land-locked seas. In this paper, we assess the POC concentration in the Gdańsk Deep, southern Baltic Sea. Our study is based on both a 1D POC Model and current POC concentration measurements. The aim is twofold: (i) validation of simulated concentrations with actual measurements, and (ii) a qualitative assessment of the sources contributing to the POC pool. The POC model consists of six coupled equations: five diffusion-type equations for phytoplankton, zooplankton, pelagic detritus and nutrients (phosphate and total inorganic nitrogen) and one ordinary differential equation for detritus at the bottom. The POC concentration is determined as the sum of phytoplankton, zoo-plankton and pelagic detritus concentrations, all expressed in carbon equivalents. Bacteria are not simulated in this paper. The observed large fluctuations of POC concentrations are attributed to its appreciable seasonal variability. The maximum concentration of POC varied between 870 mgC m−3 in May and 580 mgC m−3 in September, coinciding with the period of maximum dead organic matter and phytoplankton biomass concentrations. The results of the numerical simulations are in good agreement with observed values. The difference between the modelled and observed POC concentrations is equal to 3–28% and depends on the month for which the calculations were made, although no time trend of the difference is observed. The conclusion is that the numerical simulations are a ufficiently good reflection of POC dynamics in the Baltic.

Opis:: This paper summarises current knowledge of goods and services in the Polish Exclusive Economic Zone of the Baltic Sea ecosystem. It reviews specific properties of the Baltic that could be used for economic valuation. Goods and services range from the familiar resources of fish and minerals, which were valued with the Productivity Method, to less obvious services provided by the ecosystem such as biofiltration in coastal sands, valued with either the Replacement Cost or Damage Cost Avoided methods. Disservices to the marine ecosystem are also considered, e.g. erosion and coastal flooding, including the costs of planned mitigating measures. This paper emphasises the importance of using valuation methods to help make better-educated decisions for the sustainability of the Baltic Sea.
