Secchi depth
Opis:
This paper presents the results of a Secchi depth data mining study for the North Sea – Baltic Sea region. 40,829 measurements of Secchi depth were compiled from the area as a result of this study. 4.3% of the observations were found in the international data centers [ICES Oceanographic Data Center in Denmark and the World Ocean Data Center A (WDC–A) in the USA], while 95.7% of the data was provided by individuals and ocean research institutions from the surrounding North Sea and Baltic Sea countries. Inquiries made at the World Ocean Data Center B (WDC–B) in Russia suggested that there could be significant additional holdings in that archive but, unfortunately, no data could be made available. The earliest Secchi depth measurement retrieved in this study dates back to 1902 for the Baltic Sea, while the bulk of the measurements were gathered after 1970. The spatial distribution of Secchi depth measurements in the North Sea is very uneven with surprisingly large sampling gaps in the Western North Sea. Quarterly and annual Secchi depth maps with a 0.5◦×0.5◦ spatial resolution are provided for the transition area between the North Sea and the Baltic Sea (4◦E–16◦E, 53◦N–60◦N).

Opis:
Phytoplankton community, diatom to dinoflagellate ratio and pigment composition in surface waters with nutrient data from April 2013 to March 2014 were monitored in the south-eastern (SE) Black Sea using high performance liquid chromatography (HPLC) and microscopic analyses. Microscopic examination revealed a total of 71 species that consist of dinoflagellate (58%), diatoms (25%) and other groups (17%). Microscopy and HPLC-based pigment analyses revealed almost similar results which suggest that the phytoplankton community is mainly composed of diatoms, dinoflagellates and coccolithophores. Fucoxanthin (mean 0.35 ± 019 μg L−1), peridinin (mean 0.18 ± 0.14 μg L−1) and 19-hexanoyloxyfucoxanthin (mean 0.24 ± 0.15 μg L−1) are prominent pigments which showed significant correlation with Diatom-C (r2 = 0.63–0.71, p < 0.05), Dinoflagellate-C (r2 = 0.49–0.80, p < 0.05) and Coccolithophore-C (r2 = 0.72–0.82, p < 0.05), respectively. Mean carbon biomass of diatoms (36.50 ± 9.72 μg L−1) was higher than that of dinoflagellates (33.32 ± 9.05 μg L−1). Significant differences were also observed in nutrient ratio (N:P and Si:N) (One-way ANOVA, p < 0.05). Results illustrate that HPLC-based pigment approach can be used for taxonomic characterisation of phytoplankton groups in the SE Black Sea. Moreover, relatively high dinoflagellate species dominancy and significant correlations between Phyto-C and marker pigments indicate that phytoplankton community composition is shifting towards much smaller groups in SE coasts of the Black Sea.

Opis:
Open-loop sulphur scrubbers must be switched off, and the fuel must be changed to low-sulphur fuel before entering German inland waters. Immediately after the scrubbers are turned off, warm exhaust gases cause the residue left in the scrubber to vaporise, leading to the increased sulphur content of the exhaust gas. The momentary increase in sulphur emissions immediately after the open-loop scrubbers are turned off has received little attention in research. This paper presents the onboard measurement results of exhaust gases and examines the effects of sulphur compounds released into the air. In this case, the observed sulphur emission peak is problematic due to the geographical location. The ship sails to the river port, passing the coastal town of Travemünde, where the exhaust gases are released. Due to this, the emissions are more harmful when compared to emissions generated in the open seas.

Opis:
Bacterial production, primary production and a number of other environmental factors were measured during six cruises in the Gulf of Gdańsk conducted in various seasons from 1995 to 2001. Bacterial production (BP) in the epipelagic layer ranged from 1.5% (April) to 80% (July) of the gross primary production (PP). Significant differences were observed between the BP/PP ratios in estuarine and open-water areas. The highest values were recorded in the coastal area and near the mouth of the river Vistula. It suggests that allochthonous organic matter has a great influence on BP. The correlations between particular parameters and regression analyses indicated that BP in the Gulf of Gdańsk depended on temperature, organic nitrogen concentration, PP, chlorophyll a concentration, organic phosphorus concentration, salinity and biochemical oxygen demand. Of all the independent variables, the temperature had the greatest impact on BP (R2 = 0.62). There was an inverse parabolic relationship between bacterial production and temperature. It appears that above a temperature of 12◦C bacterial production depended on substrates to a higher degree than on temperature. The negative correlation between BP and concentrations of mineral nitrogen and phosphorus in the annual cycle were probably due to an indirect dependence. A multiple regression equation, which included temperature and organic phosphorus concentrations, explained 78% of the variation in BP. Increasing BP resulted in an increasing biomass of bacterivorous nanoflagellates and of bacterivorous ciliates, which is indicative of bottom-up control in this segment of the trophic chain.

Opis:
The Baltic Sea is crisscrossed by several dense vessel traffic routes. Growing shipping traffic increases the likelihood of collisions. A quantitative analysis of the impact of fishing vessel traffic streams on streams of merchant vessel traffic aims to identify areas of intense traffic of this type and to assess the potential risks. The identification of intersections of fishing vessel routes and merchant shipping traffic allows us to identify spots of potential collisions. The analysis made use of the IALA IWRAP Mk2 program and AIS data collected from April 1, 2013 to March 31, 2014.

Opis:
The paper addresses the sensitivity of a novel method for quantifying the environmental risks associated with the current-driven transport of adverse impacts released from offshore sources (e.g. ship traffic) with respect to the spatial resolution of the underlying hydrodynamic model. The risk is evaluated as the probability of particles released in different sea areas hitting the coast and in terms of the time after which the hit occurs (particle age) on the basis of a statistical analysis of large sets of 10-day long Lagrangian trajectories calculated for 1987–1991 for the Gulf of Finland, the Baltic Sea. The relevant 2D maps are calculated using the OAAS model with spatial resolutions of 2, 1 and 0.5 nautical miles (nm) and with identical initial, boundary and forcing conditions from the Rossby Centre 3D hydrodynamic model (RCO, Swedish Meteorological and Hydrological Institute). The spatially averaged values of the probability and particle age display hardly any dependence on the resolution. They both reach almost identical stationary levels (0.67–0.69 and ca 5.3 days respectively) after a few years of simulations. Also, the spatial distributions of the relevant fields are qualitatively similar for all resolutions. In contrast, the optimum locations for fairways depend substantially on the resolution, whereas the results for the 2 nm model differ considerably from those obtained using finer-resolutionmodels. It is concluded that eddy-permitting models with a grid step exceeding half the local baroclinic Rossby radius are suitable for a quick check of whether or not any potential gain from this method is feasible, whereas higher-resolution simulations with eddy-resolving models are necessary for detailed planning. The asymptotic values of the average probability and particle age are suggested as an indicator of the potential gain from the method in question and also as a new measure of the vulnerability of the nearshore of water bodies to offshore traffic accidents.

Opis:
W opracowaniu przedyskutowano zagrożenia środowiska morskiego i jego składowych w następstwie zatopienia w Morzu Bałtyckim w okresie po II wojnie światowej amunicji chemicznej zawierającej bojowe środki trujące (BŚT). Biorąc pod uwagę przebieg korozji różnych znalezionych w morzu pojemników metalowych zawierających BŚT oraz kontaktów z pozostałościami amunicji chemicznej, oszacowano, że prawdopodobnie większość amunicji uległa korozji. W wyniku tego procesu, niebezpieczne związki chemiczne (BŚT) wydostały się do środowiska morskiego i uległy rozkładowi (hydrolizie) do związków nietoksycznych lub słabo toksycznych. Nie można też wykluczyć, że amunicja chemiczna pogrążona w głębszych warstwach osadów dennych, gdzie panują warunki beztlenowe, nie uległa jeszcze całkowitej korozji. Na podstawie analizy właściwości chemicznych bojowych środków trujących oraz warunków środowiskowych w morzu wykazano, że nie ma groźby wystąpienia katastrofy ekologicznej, ponieważ związki chemiczne stanowiące BŚT tracą zdolność masowego rażenia w zetknięciu z wodą. Wykazano także, że nie ma żadnego niebezpieczeństwa dla konsumentów ryb bałtyckich (nawet gdyby ryba miała kontakt z BŚT), gdyż w trakcie przygotowania ryby do konsumpcji związki te ulegną rozkładowi i stracą pierwotne właściwości toksyczne. Nie ma także groźby skażenia ryb, jako że zarówno BŚT, jak i produkty ich rozkładu nie przechodzą do łańcucha pokarmowego. Oceniono, że najpoważniejszym niebezpieczeństwem dla rybaków jest obecnie zbrylony iperyt, który w środowisku morskim nie podlega szybkiemu rozkładowi i może być wyławiany w trakcie trałowania dna. Wskutek wysokiej dynamiki przybrzeża morskiego istnieje możliwość pojawienia się pozostałości amunicji chemicznej na brzegu morskim (w tym także zbrylonego iperytu), co w przypadku niezamierzonego kontaktu z takim znaleziskiem stanowi zagrożenie dla zdrowia. Wykazano, że propozycje i plany wydobywania amunicji chemicznej z Bałtyku są niewykonalne, gdyż wskutek rozproszenia amunicji chemicznej na całym obszarze południowego Bałtyku oraz pogrążenia się części amunicji w osadach dennych nie ma realnej możliwości oczyszczenia Bałtyku z tych pozostałości.
The study discusses the threat of the marine environment and its components following the dumping of chemical munitions containing chemical warfare (CW) agents in the Baltic Sea in the period after the Second World War. Considering the course of corrosion of the various metal containers with CW agents found in the sea and a contact with the remains of chemical munitions it was estimated that probably most of munitions have corroded. As a result of this process, dangerous chemicals, i.e. CW agents, were released to the marine environment and decomposed (hydrolyzed) into non-toxic or less toxic compounds. Nevertheless, it cannot be excluded that chemical munitions remain in deeper layers of sediments, where anaerobic conditions prevail. Based on the analysis of the properties of chemical warfare agents and environmental conditions in the sea it has been demonstrated that there is no threat of ecological disaster, as the chemical compounds constituting the CW agents lose the ability of mass destruction when exposed to water. It was also shown that there is no danger to consumers of the Baltic fish (even if a fish had a contact with CW agents), as during the preparation of the fish for consumption, these compounds will decompose and lose their primary toxic properties. There is also no risk of contamination of fish tissue, as the CW agents, and their decomposition products, do not enter the food chain. It has been assessed that the most serious danger to fishermen are now lumps of mustard gas, which are not quickly decomposed in the marine environment and may be collected during bottom trawling. Due to the high dynamics of the marine foreshore, there is a possibility of the occurrence of chemical munitions’ remains on the sea shore (including lumps of mustard gas), which in the case of an accidental contact with such a discovery, poses a threat to health. It has been indicated that the proposals and plans for the removing of the remains of chemical munitions from the Baltic Sea are not feasible, as due the dispersion of CW agents throughout the southern Baltic area and their deposition in bottom sediments, there is no real possibility of cleaning the Baltic Sea from these remains.

Opis:
Access to the Baltic Sea was the main initial goal of Russia’s participation in the Great Northern War (1700–1721). This military involvement was primarily due to the personal motives of Peter the Great, however, numerous different factors also played an important role. The foundation of St Petersburg, making it the capital city, and fortifying it with a defensive system was aimed at securing the Russian control over the mouth of the Neva. The military operations and diplomatic efforts undertaken by Russia in 1702–1709 were aimed exclusively to maintain access to the sea. At this time, Russia was ready to agree to the peace terms which were to grant it only the old Russian provinces of Ingria and Karelia. However, after the victorious Battle of Poltava of 1709, Peter the Great developed imperial ambitions. Under the pretext of ensuring the security of St Petersburg and ensuring Russia’s access to the sea, the Russians captured Swedish lands in the Eastern Baltic and Finland, and then annexed most of these territories. At the same time, Russian diplomacy constantly ensured of its readiness to conclude peace, but these attempts were rejected by the Swedes. Ten years of warfare and destructive raids on the coastal regions of the Kingdom of Sweden forced the Swedes to negotiate. The Treaty of Nystad of 1721 not only ended the war between Russia and Sweden, but it also became the starting point of the extraordinary development of Peter the Great’s imperial ambitions. Russia entered the world of great European and global politics as an empire, as an aggressive state of despotic character.

Opis:
The second formulation of Boccotti’s quasi-determinism theory is investigated. Deep water wave records collected in the Baltic Sea with AWAC (Nortek Acoustic Wave and Current profiler) are used in this study. The adequacy of Boccotti’s theory for Baltic Sea conditions is evaluated on the basis of some simulations of wave groups with a very large maximum wave height. The large waves are chosen using an abnormality index (ratio of maximum wave height to significant wave height) with a value greater than 2. Such values of this index are also used by different authors for the definition of freak waves. In order to obtain better results, JONSWAP formula is fitted to the measured spectra instead of using default JONSWAP parameters for the simulations. Verification of values of spectral parameters obtained from the autocovariance function against the same parameters calculated from smoothed and not smoothed spectra is presented. Much attention is given to spectral peak period value. The spectral width parameter, in QD theory known as narrow bandedness parameter, requires further investigation as the results obtained here did not allow the formulating of any functional relation with another – more often used – spectral width parameter. The low frequency of sampling of the data allowed only the most important aspects of the theory to be checked. A short Matlab function used in QD simulations is presented.

In July 2000 the diurnal cycle of analyses was conducted in order to determine variation in the concentrations of nitrogen and calcium compounds as well as dissolved gases in surface microlayers of a shallow coastal barrier lake located at the Baltic Sea coast. Water for analyses was collected in a diurnal cycle for the period of 24 h from lake Dołgie Wielkie. The analyses were conducted on the surface microlayer with a thickness of approx. 100 μm, a layer with a thickness of approx. 250 6m and a layer of subsurface water from a depth of 15 cm. Based on the analyzed data, information was collected on the migration of nitrogen compounds between the analyzed layers. Changes were observed in nitrogen forms reduced to oxidized forms and vice versa.

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:
The area of the Coastal Landscape Park (CLP) due to its location is extremely attractive touristic area. In the summer season, a significant increase in population density is observed, which influences surface water quality. Large numbers of tourists generate an increased amount of municipal wastewater, being treated in local treatment plants and discharged into rivers and streams. The paper presents preliminary research from summer 2016 on three watercourses ending in the Baltic Sea: Piaśnica, Karwianka and Czarna Wda rivers. It is a part of a long-term project conducted in CLP to assess surface waters quality. The scope of research included measurements of in situ parameters (temperature, conductivity, pH, dissolved oxygen). Chemical Oxygen Demand was determined using a spectrophotometer. Ion chromatography was used to determine ions concentrations (including biogenic compounds). Sanitary state of watercourses was assessed based on fecal coliforms abundance, which number was determined by the cultivation method. The determination of microbiological parameters such as: prokaryotic cell abundance expressed as total cells number (TCN), prokaryotic cell biovolume expressed as average cell volume (ACV), the prokaryotic biomass (PB) and prokaryotic cell morphotype diversity was determined using epifluorescence microscopy method. Results showed that water quality of Piaśnica and Czarna Wda rivers were affected by discharged treated wastewater. In the case of Karwianka River, the main pollution source could be surface runoff from fields and unregulated sewage management in this area.
