Opis:
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.

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.

Opis:
Intense rain in the south em part of the Vistula 's watershed in Ju(v 2001 resulted in floods in many places and in flood water flows on the Vistula and its tributaries. 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.

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.

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:
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 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.

Opis:
The primary purpose of the paper is to identify port areas most exposed to extreme hydrodynamic conditions (waves, sea currents, seabed level change). The results of modelling using SWAN wave model, MIKE 3D model, and reanalysis and measurement data were used in paper. Swell may exceed 0.8 m for winds exceeding 15 m s-1 from the west and south. During extreme conditions, sea currents can reach 0.4 ms-1 in the outer part of the bay adjacent to the port. Port basins do not show changes in the thickness of the seabed for the given maximum values of bottom currents. The most extensive deposition of the seabed and shore sediments (up to 0.04 m) is found on the Gdynia-Oksywie beach adjacent to the port and the approach fairway at the offshore currents. The outer area of the main breakwater is the most exposed to erosive activity (-0.012 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:
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:
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.
