    Gulf of Finland
    Opis:
    The development of the coastal zone of the eastern Gulf of Finland has a long geological history and depends on the several main factors. The primary configuration of the shoreline is connected with tectonic movements, which even at present are displayed in slow uplifting of the northern coast and slow sinking of the southern one. However, the main features of the recent coastal zone were formed during degradation of the last glacial cover and essentially transformed during post-glacial period of different water bodies’ existence. The processes of the modern morpho- and litho-dynamic are very changeable and expressed in the different accumulative and erosion forms of relief. The anthropogenic activity during last centuries results in local reconstruction of the conditions of existence and development of the coastal zone.

    Opis:
    In July–September 2004 and April 2005, the specialists of the Department of Marine and Environmental Geology of All-Russian Geological Institute (VSEGEI) conducted field studies of the coastal zone of the Gulf of Finland from thesouthern alignment of the St. Petersburg Flood Protective Dam to Lebyazhye. The basic purpose of the studies is the analysis of coastal zone dynamics. Along the southern coast of the Gulf of Finland from Lebyazhye to the Dam, three different coastal dynamics zones were identified: (1) flat accumulative shore with aquatic plants, (2) erosion zone and (3) zone of modern sand accumulation. Along-shore sand drift in the eastern direction was also determined. Alongside with routine observations, the comparative analysis of space photography images of the study area, carried out during last 20 years, allowed finding out that as a result of intense eastward sand transfer, as mush as 80 metres of sand accumulative bodies have been eroded since 1982 near the village of Izhora. To the west of a small river, a 230-metres long sand split has been formed since 1982.

    Opis:
    Zgodnie z rosyjską strategią morską, Morze Bałtyckie jest najważniejszym szlakiem wymiany handlowej Rosji z państwami europejskimi. Modernizacja, rozbudowa i budowa nowych portów Rosji dotyczy głównie Sankt Petersburga i Zatoki Fińskiej. Wzrost możliwości przeładunkowych portów pozwoli na maksymalne zmniejszenie uzależnienia Federacji Rosyjskiej od przewozów tranzytowych. Przeładunki głównych portów rosyjskich w Zatoce Fińskiej stanowią ponad 85% całkowitych obrotów rosyjskich portów bałtyckich. Porty w Ust-Łudze i Primorsku w 2015 roku odnotowały największe obroty. W latach 2008–2015 przeładunki w Ust-Łudze wzrosły ponad 11-krotnie. Sankt Petersburg jest największym portem kontenerowym w regionie Morza Bałtyckiego. Port nie może się dalej rozwijać z uwagi na brak wolnych terenów. Jest to spowodowane bezpośrednim sąsiedztwem miasta Sankt-Petersburg. W końcu 2015 roku do grupy najnowszych portów kontenerowych i ro-ro dołączył port Bronka. Docelowo port ten ma stać się „główną bramą dla kontenerów płynących do Rosji”.
    According to the Russian maritime strategy, the Baltic Sea is for Russia the most important trading route to European countries. Modernisation, development and the construction of new ports in Russia concentrate in Sankt Petersburg and the Gulf of Finland. The growing cargo handling capacity of ports will lead to reducing the dependence of the Russian Federation on transit transport. Cargo volumes handled by main Russian ports in the Gulf of Finland constitute over 85% of the total turnover of Russian ports on the Baltic Sea. The ports in Ust-Luga and Primorsk noted their biggest turnover in 2015. In the years 2008-2015, cargo volumes in Ust-Luga rose eleven fold. Sankt Petersburg is the biggest container port in the Baltic Sea Region. The shortage of development areas, caused by the urban built-up of Sankt-Petersburg, has exhausted further port development. At the end of 2015, Bronka Port joined the group of the newest container and ro-ro ports. The port is to become the key gate for containers sailing to Russia.

    Opis:
    The purpose of this study was to assess the groundwater contamination from a sewage sludge landfill. The analysis was carried out in 2017 in accordance with the requirements of the national legislation for monitoring landfills and priority pollutants. The samples of groundwater from the landfill were taken from 25 observation wells, from depths of 45–60 m. The status and dynamics of changes in the landfill groundwater quality were estimated according to the data from the groundwater observation wells of the city observation network with regard to the chemical composition of groundwater and national standards of groundwater quality. The forecast estimates of a low level of pollutants entering groundwater through the soils characterized by low filtration properties were not justified. The concentration of heavy metals in groundwater was within the following range: Fe > Mn > Zn > Al > Cu > Ni > Pb > Cd > Hg. The excess concentration of the nitrogen-containing pollutants was observed within the range from 1.5 to 76 (on average 10 times) above the background value. The organic contamination of landfill groundwater (COD) is 2–9 times and BOD5 – 1.5–3 times higher than the average background value of groundwater observation wells in the city network. The probable cause for the pollutants entry into groundwater is associated with lithogenous and exogenous fracturing of the rocks and insufficient efficiency of the existing anti-filtration system of the landfill.

    Opis:
    In the current study we use a three-dimensional model with hydrodynamic and spectral wave modules operating in a coupled mode to simulate the response of currents and wind wave fields to winds of 20–25 m/sec offshore of the protective structure of the Saint Petersburg Flood Prevention Facility Complex. The model was calibrated against field data, which allowed us to obtain a tool describing storm situations in the eastern part of the Gulf of Finland with a satisfactory accuracy. The numerical modeling showed that the protective dam did not have a noticeable effect on the levels of stormsurge, significantwave height, or current speed in areas seaward of the dam. The increase in erosion processes on the southern shore of the easternmost part of the Gulf of Finland in recent past has most probably been related to other factors. We found that if a west or south-west wind of at least 25 m/s blows over the Baltic Sea for at least 16 hours, the level of storm surges seaward of the dam may reach 3 or more meters. An artificial strengthening of the coastline and the creation of shore protection structures are recommended.

    Sea accidents are aimed to be prevented with an extensive amount of maritime safety regulation. The purpose of this paper is to present the findings of a questionnaire study that was targeted at Finnish maritime experts and addressed the question: how to prevent an oil accident in the Gulf of Finland. This study also includes a literature study about the problems of the current maritime safety regime. The findings of the questionnaire study are compared to the findings of the literature study. The questionnaire study showed that many kinds of policies have improved maritime safety, and they are needed to ensure maritime safety. For instance, ship construction, fairway maintenance, nautical charts and rules of the road at sea can be considered the cornerstones of maritime safety. However, the results ranked voluntary activities of companies as the most effective way to improve maritime safety in the future. Self-regulative approaches could solve some problems connected to more traditional policy-making.

    This paper covers the current state of maritime oil transportation in the Baltic Sea and the development of oil transportation in the 2000s, as well as estimations of transported oil volumes in 2020 and 2030 in the Gulf of Finland. The scenarios were formulated on the basis of a current state analysis, energy and transportation strategies and scenarios and expert assessments. The study showed that the volumes of oil transportation in the Gulf of Finland will increase only moderately compared to the current status: 9.5-33.8 %, depending on the scenario. Green energy policy favours renewable energy sources, which can be seen in the smaller volumes of transported oil in the 2030 scenarios compared to the 2020 scenarios. In the Slow development 2020 scenario, oil transport volumes for 2020 are expected to be 170.6 Mt (million tonnes), in the Average development 2020 187.1 Mt and in the Strong development 2020 201.5 Mt. The corresponding oil volumes for the 2030 scenarios were 165 Mt for the Stagnating development 2030 scenario, 177.5 Mt for the Towards a greener society 2030 scenario and 169.5 Mt in the Decarbonising society 2030 scenario.

    Opis:
    The paper presents a model for risk analysis regarding marine traffic, with the emphasis on two types of the most common marine accidents which are: collision and grounding. The focus is on oil tankers as these pose the highest environmental risk. A case study in selected areas of Gulf of Finland in ice free conditions is presented. The model utilizes a well-founded formula for risk calculation, which combines the probability of an unwanted event with its consequences. Thus the model is regarded a block type model, consisting of blocks for the probability of collision and grounding estimation respectively as well as blocks for consequences of an accident modelling. Probability of vessbl colliding is assessed by means of a Minimum Distance To Collision (MDTC) based model. The model defines in anovel way the collision zone, using mathematical ship motion model and recognizes traffic flow as a non homogeneous process. The presented calculations address waterways crossing between Helsinki and Tallinn, where dense cross traffic during certain hours is observed. For assessment of, a grounding probability, a new approach is proposed, which utilizes a newly developed model, where spatial interactions between objects in different locations are recognized. A, ship at a seaway and navigational obstructions may be perceived as interacting objects and their repulsion may be modelled by a sort of deterministic formulation. Risk due to tankers running aground addresses an approach fairway to an oil terminal in Skoldvik, near Helsinki. [...]
    W artykule przedstawiono model oceny ryzyka w transporcie morskim, w aspekcie kolizji statków oraz wejść na mieliznę. W modelu przyjęto jeden typ statków, tankowce do przewozu ropy naftowej, z uwagi na fakt, iż w przypadku wystąpienia kolizji lub kontaktu z dnem statek ten może stanowić bardzo poważne zagrożenie dla środowiska. W pracy przedstawiono dwa nowatorskie podejścia do modelowania prawdopodobieństwa wystąpienia powyższych wypadków. Model do oceny prawdopodobieństwa kolizji statków definiuje w nowy sposób strefę kolizji, w oparciu o właściwości manewrowe statku oraz jego hydrodynamikę. Intensywność ruchu morskiego na analizowanym akwenie modelowana jest w oparciu o proces niestacjonarny, w przeciwieństwie do istniejących modeli. Model oceny prawdopodobieństwa wejścia na mieliznę wykorzystuje model grawitacyjny, który wyznacza bezpieczny obszar manewrowy dla danego statku i danego akwenu. W modelu tym statek i otaczające go płycizny traktowane są jako masy, wzajemnie na siebie oddziaływujące. Obydwa modele wykorzystują dane o ruchu statków zarejestrowane w systemie automatycznej identyfikacji statków (AIS). Analiza ryzyka przeprowadzona została dla dwóch wybranych akwenów w Zatoce Fińskiej. Jako konsekwencje wypadku przyjęto model kosztów, skonstruowany w oparciu o dane statystyczne z międzynarodowego funduszu IOPCF, który pokrywa koszty w związku z rozlewem olejowym na morzu.
