Gulf of Gdańsk
Opis:
Since many years, in the Gulf of Gdańsk various transformations proceeding under the influence of trophic and pollution-induced factors are observed. Changes of especially negative character were found in the biocenosis of the Puck Bay, in which many plant and animal sets became degraded or even devastated. Besides, at present the public feels endangered by bacterial pollution of the coastal zone and increasingly intensive phytoplankton blooming. This limits the possibilities of using these water areas for the needs of tourism and recreation. It was decided that comprehensive activities should be started, both on land and in the Bay itself, in order to limitlremediate the effects of eutrophication of this water area. In 1994 and 1995 monitoring and experimental investigations were carried out. In effect a system for protecting and restoring the biocenosis was developed, and the main assumptions for this system are presented in this paper.

The paper discusses the distribution of salinity and of dissolved non-organic salts of nitrogen and phosphorus (nitrates, nitrites, ammonium, phos;hates) in the surface waters of the Gulf of Gdańsk after the flood wave passed in the IIIrd decade of July 1997. It was found, by comparing with data obtained in the past years, that the summer flood wave did not cause large changes in the amounts of the investigated biogenic substances in the waters of the region.

Opis:
Bottom structure of the basins in the Port of Gdynia, Poland, was analysed based on the archival materials of the Department of Operational Oceanography of Marine Institute in Gdańsk, particularly seismic profiles and macroscopic descriptions of sediment cores. Seismic profiling and core collection were performed in selected basins and within the fairway. The rich source material was used to draw a detailed bathymetric map of the bottom of the basins, a map of surface sediments, and a synthetic geological cross-section. A considerable variation in bottom depth within the analysed basins was observed. Bedrock sediments comprised Miocene sands and silts covered with glacial and fluvioglacial sediments, which reach the surface of the water, especially in the central part of the fairway. Within the eastern part of the fairway, fluvioglacial sediments are covered with marine sediments related to the Littorina transgression. Within the inner port and in the outport, a series of glacial and fluvioglacial sediments are covered with a thick (about 10 m) series of glaciolacustrine and lacustrine sediments, which in turn is covered with fluvial and deltaic sediments. The surface of the bottom is composed of contemporary, anthropogenically modified sediments. The map of surface sediments of the bottom corresponds to the geological map on the horizon of about 10 meters beneath land surface.
W ramach opracowania budowy dna basenów portowych Portu Gdynia wykorzystano materiały archiwalne Zakładu Oceanografii Operacyjnej Instytutu Morskiego w Gdańsku, tj. profile sejsmiczne oraz opisy makroskopowe rdzeni osadów. Profilowanie sejsmiczne oraz pobór rdzeni wykonano w wybranych basenach oraz w obrębie podejściowego toru wodnego. Bogaty materiał źródłowy posłużył do opracowania szczegółowej mapy batymetrycznej dna basenów, mapy osadów powierzchniowych oraz syntetycznego przekroju geologicznego. Stwierdzono znaczne zróżnicowanie głębokości dna w obrębie analizowanych akwenów. Osady podłoża to piaski i muły mioceńskie, na których zalegają osady lodowcowe oraz wodnolodowcowe wychodzące – zwłaszcza w centralnej części podejściowego toru wodnego – na powierzchnię. W obrębie wschodniej części toru wodnego na osadach wodnolodowcowych zalegają osady morskie związane z transgresją litorynową. Na obszarze portu wewnętrznego oraz w awanporcie seria osadów lodowcowych i wodnolodowcowych przykryta jest miąższą (około 10 m) serią osadów jeziorno-lodowcowych i jeziornych, na których zalegają osady o charakterze rzecznym i deltowym Powierzchnię dna budują osady współczesne, zmienione antropogenicznie. Mapa osadów powierzchniowych dna odpowiada mapie geologicznej na poziomie około -10 m.

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:
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.

The culmination of the flood reached the Gulf of Gdańsk in the night of 5th August 2001. In the period 4th to 6th August, 10 samples of water were taken, and d1e content of biogenic substances and of other components in these samples was determined. Basing on water flow measurements and on the content of the investigated components, the loads were calculated and compared with mean multi-annual loads for the pen·od 1984- 1998. It was found that the mean biogen load, related to water flow, was exceeded many times. Also the relationships between the analysed components, water flow and variability during the period of investigations were detennined. Obtained results show that there may be a very significant influence of biogens on the condition of the environment and on the dynamics of biocenotic processes of the Gulf of Gdańsk in the period before and after the propagation of flood waters of the Vistula.

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.

The research area is located on the coast of the Baltic Sea, along the Gulf of Gdańsk. It includes a beach where sand replenishment was carried out in 2019. The aim of the study was to investigate the morphodynamics of beach deposits in replenishing and non-replenishing areas during one year. No environmental dynamic conditions sufficient to alter significantly the beach morphology and sediment characteristics occurred during the study period, November 2019 to August 2020. One storm event was recorded, but did not significantly affect the beachform. The transverse beach profiles, which were artificially recharged in June 2019, were lowered by 0.6 to 1.2 m. The greatest changes were caused by the erosive activity of the waters of the Jelitkowski Stream.

The application of nonlinear backscattering of acoustical signals in detection of gas bubbles in subsurface layer of sediment of the Gulf of Gdansk is presented. Gas bubbles concentration was estimated assuming that nonlinear scattering in soft sediments is similar as in water. Summary, difference and double harmonics generated only by gas bubbles were recorded and used for bubble density estimation. Comparisons of the concentrations received from different nonlinear components show generally agreement in calculated bubble density distributions, although values of densities acquired from almost identical volumes in a single transmission differ.

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.

This study is intended to make a first estimate of the exposure of the two Polish largest ports – Gdańsk and Gdynia, localized in the Gulf of Gdańsk – to threats from storm extremes. These ports are elements of the Polish critical infrastructure and presented analysis is one of the tasks related to critical infrastructure protection. Hypothetical extreme meteorological conditions have been defined based on 138-year NOAA data and assumed wave fields for those conditions have been generated. Using HIPOCAS project database the 21 extreme historical storms over the period 1958–2001 were selected to simulate realistic conditions in the vicinity of the ports. The highest significant wave height was found to be nearly 4 m in the vicinity of Port of Gdańsk and nearly 2 m in the vicinity of Port of Gdynia. A future intensification of these wave conditions should be considered due to the climate change and sea level rise.

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:
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.
