    Gulf of Gdansk
    Opis:
    The subject of marine vessel as a source of the sea pollution was taken because of very adverse impact of petroleum pollutants on the natural environment. Oil pollutions concern especially marine environment. However, petroleum inflows to the sea from many different sources, exploitation of the fleet are one of the significant causes of oil presence in the marine environment. MARPOL Convention requires the states parties thereto to monitor the state of contamination [3] and this is a second reason of taking this subject. During the past years, several tests of petroleum content in the Gulf of Gdansk were made by the Physics Department of Gdynia Maritime University. In total 115 samples of water were collected and analyzed during the period from 2004 to 2009 year in the Gulf of Gdansk, which is an area of intense ships traffic because of two great complexes of harbours located in Gdansk and in Gdynia. These tests were carried out with the help of Institute of Oceanology Polish Academy of Sciences during cruises of the r.v. “Oceania”. Petroleum concentration in seawater was determined by means of improved fluorescence method. Oil in water concentration ranged from value below of the detection limit, that is 10–9 (less than 1 ppb), up to 3.5ź10–7 (350 ppb). Average concentration of oil was 4.3ź10–8 (43 ppb). Obtained results confirmed that Vistula River could be a source of petroleum pollution of the Gulf of Gdansk. Apart from this, vessels are the significant sources of oil in the seawater too. The most polluted places were founded in the area where ships crossed the Gulf of Gdansk.

    Opis:
    The increasing climatic changes and their possible negative impact on the marine and coastal environment prompt the search for alternative estimating and predicting dangerous phenomena. Hydrodynamic modeling is an underappreciated model which enables forecasting waves and their effects. In the presented work, the author assessed the influence of the dynamics of undulations on the morphological changes of the Gulf of Gdańsk coast in three transects representing different geomorphological zones of the shore. Using the SWAN wave model, simulations were carried out reflecting the hydrodynamic conditions of the most giant storms in 2015-2020, calculating the amount of eroded sediment material in bottom and suspension transport. In addition, based on the significant wave height data from ERA5-ECMWFfrom 1981-2020 and the assumed scenarios, a prediction was made of a potential increase in coastal erosion caused by the rise in the mean value of the significant wave height. Taking into account the implemented and set atmospheric, hydrodynamic, and sedimentological conditions, it has been estimated that the highest erosion characterizes the cliff area in Gdynia-Orłowo (transect B), where the average amount of erosion of the bottom sediment is 0.5 kg/m/s, of the sediment in suspension - 20 kg/m/s, and the average speed of the transported sediment exceeds 2 m s-1. The lowest dynamics of changes is characteristic for the western part of the Vistula Spit (transect C), where the average velocity of the transported sediment is 0.28 m s-1, and the average size of the eroded bottom sediment is 0.014kg/m/sand 0.15kg in suspension/m/s. In the analyzed storm events, at all locations, the greatest erosion was generated by the wave conditions from January 2019. The maximum wave height in the open sea was record-breaking, over 13 meters. Depending on the analyzed area and its geomorphology and exposure to storm waves, the predicted amount of erosion varied significantly. For Scenario A, assuming a 15% increase in the average frequency and height of the significant wave, the forecast of coastal transport is 138-161 thousand m3/year, for Scenario B (30%) 150-175.5 thousand m3/year, and for Scenario C (50%) 180-210 thousand m3/year. In addition, the aim of the work is a cause-and-effect analysis of wave activity on the coast of the Gulf of Gdańsk and the assessment of its impact on quantitative changes in the sediment transport balance.

    Opis:
    Climate change and its consequences, including rising ocean temperature and sea level rise are well scientifically documented. The changes are especially severe for coastal communities, which are estimated to have reached c. 50% of the world’s population. Using an example of the Gulf of Gdansk region, which is of European importance, due to the presence of two major Baltic ports and global tourism, we explore, how sea related threats may affect the region and we analyse how the three major cities are prepared to these threats. The four city developmental strategies and an additional document, an “umbrella strategy” focusing on climate change threats do not consider sea level rise and more frequent storm surges as threats. The sea level rise is briefly discussed in the fourth document. The adaptation plan, an appendix to the document, mentions sea level rise, but the discussion of the problem is indirect and involves some examples of adaptation actions in loosely similar environmental conditions. The adaptation plan, in fact includes a list of possible threats, rather than a detailed discussion of the suggestions of the measures to be undertaken. For comparison, we present a multilevel approach, which is effectively run in the Port of Rotterdam and argue that such approach should be undertaken in the studied region. We conclude that despite years of education on climate change, the problem is still not recognised and is underrepresented in practical measures of the studied region. We also provide hints on how to overcome this situation.

    W artykule przywołano przykłady udanych wdrożeń obiektów hydrofitowych oczyszczania spływów obszarowych na terenie aglomeracji trójmiejskiej. Zespół obiektów hydrofitowych wybudowany w ZOO w Oliwie wykazał szczególnie wysoką skuteczność usuwania związków azotu. Obiekt hydrofitowy na Potoku Swelina spowodował znaczną poprawę jakości wód Potoku, a co za tym idzie i czystości kąpieliska w rejonie Kamiennego Potoku w Sopocie. Podjęte działania przyczyniły się do znacznej poprawy jakości wód Zatoki Gdańskiej w rejonach kąpielisk w Jelitkowie i Kamiennym Potoku.
    In the article the examples of successful application of CW systems for treatment of aerial runoff at the Threecity agglomeration have been presented. The CW system at the ZOO in Oliwa was particularly effective in nitrogen removal. The CW system at Swelina Stream contributed to the significant improvement of the stream waters quality, resulting in the improvement of the quality of the bathing place located near its outflow to the Gulf of Gdańsk.

    Opis:
    Carbonate cementation of sandy sediments is most common in tropical and subtropical climate, and quite rare in temperate climate. About 20 sites where carbonate cemented sandstones occur are known throughout the Polish Lowlands. A new outcrop of carbonate cemented sandstone was found near Gdynia-Orłowo (coast of the Gulf of Gdańsk). Field studies and microscopic analyses [optical microscopy and SEM] let to recognise the pattern of cementation of sandy sediments. Origin of the sandstones is connected with infiltration of rain water into glacial till (partially cracked). This till is the source of calcium carbonate transported by water into underlying fluvioglacial sands. Because of different sediments porosity and resulting degassing of CO2, CaCO3 precipitated. Additionally, elevated temperature and evaporation of water may also create favorable condition for precipitation. The process of cementation is related to the exposition of fluvioglacial sands layer caused by cliff abrasion (about 1 m per year). The best geochemical conditions for precipitation of CaCO3 are in the zone of contact with atmosphere, so this cementation seems to be recent. Carbonate cemented sandstones formed below the glacial till fall down and may be found in the colluvium of the cliff slope.

    Opis:
    The Vistula River mouth is an unique example of river’s outlet observed since the birth in 1895 to present day. There is a large documentation of morphological changes in the outlet area. In 1895, a 7 kilometres canal was dug into which the waters of the Vistula were let in. Since 1895, most of the water discharge and all sediment transport reach the Gulf through artificial channel c. 20 km east of Gdańsk. During the last 100 years, the shoreline has been shifted seaward c. 1.5 km on the eastern side, to c 2.5 km on the western side of the Vistula mouth. Isobath of 5 m moved seaward c. 3 km and isobaths of 10 and 15 m shifted 2.5 km. During the years 1895-1997, land area accreted to 3,019,000 m2. The volume of the river-outlet cone in the year 2000 was 133.39 mln m3 and the average rate of sediment growth over the 105 years was c. 1.27 mln m3 per year.

    Opis:
    Detection of small crafts/targets, in particular, sailing yachts with the ship's radar is not always possible. Radar reflectors are used to improve their detection. The AIS (Automatic Identification System) transmits position, motion vector and identification signals of a vessel to other ships and VTS (Vessel Traffic Services) centers . This system significantly increases the possibility to detect small crafts. The paper presents results of comparative study of using information from the Automatic Identification System and from radar to determine the accuracy of tracking the position and motion vector of ships in the Gulf of Gdansk. Possibilities and limitations of the AIS are also presented.

    Opis:
    Non-indigenous gammarid species: Pontogammarus robustoides (G.O.Sars, 1894), Obesogammarus crassus (G.O. Sars, 1894), Dikerogammarus haemobaphes (Eichwald, 1841) and Dikerogammarus villosus (Sowinsky, 1894) are present in the Gulf of Gdańsk (southern Baltic Sea). These species reached the Gulf of Gdańsk by 2010 near the point where the River Vistula flows into the Baltic Sea, and become constituents of the amphipods in shallow bottom. All the gammarid species found are of Ponto-Caspian origin. They have been able to move across Europe along rivers and canals, and inhabit reservoirs and drainage systems in the vicinity of such waterways. D. villosus is the latest gammarid species to have colonized Poland. The floods that afflicted Poland in May and June 2010 could have had a significant influence, intensifying as they did the inflow of water from the Vistula into the Gulf of Gdańsk. This could have accelerated the arrival of individuals of these species. The water salinity at the sampling stations was 5.8 – 6.1 PSU. The possible invasion of non-native gammarids may have important consequences for the benthic fauna communities in the Gulf of Gdańsk.
    Nierodzime gatunki kiełży: Pontogammarus robustoides (G.O.Sars, 1894), Obesogammarus crassus (G.O. Sars, 1894), Dikerogammarus haemobaphes (Eichwald, 1841) and Dikerogammarus villosus (Sowinsky, 1894) obecne są już w Zatoce Gdańskiej (Bałtyk Południowy). Gatunki te pojawiły się w Zatoce Gdańskiej w 2010 roku, niedaleko ujścia Wisły do Bałtyku i stały się składnikiem obunogów płytkiego dna. Wszystkie wymienione gatunki są pochodzenia ponto-kaspisjkiego. Przedostały się do Europy rzekami i kanałami, i zasiedlają zlewnie tych rzek. D. villosus jest najnowszym przybyszem, który skolonizował Polskę. Najprawdopodobniej powódź, która dotknęła Polskę w maju i czerwcu 2010 roku zintensyfikowała napływ wód Wisły do Zatoki Gdańskiej. Przyśpieszyło to przedostanie się osobników wymienionych gatunków do Zatoki Gdańskiej. Zasolenie wody na stacjach zbioru materiału wynosiło od 5.8 do 6.1 PSU. Inwazja nierodzimych gatunków kiełży może znacznie wpłynąć na zespoły bentosowe Zatoki Gdańskiej.
