Opis:
The waters of the Celebes Sea are an area that has quite complex dynamics because it is influenced by several factors, either regionally or globally. This influence certainly has an impact on variations in oceanographic conditions in waters such as Sea Surface Temperature (SST) and sea currents. Currently, there are many observations of oceanographic data, one of which is by using remote sensing methods. The purpose of this study was to determine the seasonal variations in sea surface temperature and sea surface currents in the Celebes Sea using a remote sensing system in a time series for 5 years (2014-2018). The results of this study indicate data on seasonal variation of SST and sea surface currents have an average maximum SST value for 5 years occurring in the eastern season and the second transitional season (May, June, July) with an average value range of 30.6 °C - 31.1 °C and the average maximum sea current velocity for 5 years occurs in the western monsoon with a value range of 0.72 m/s - 0.77 m/s. The high SST value and sea current velocity are caused by the influence of the season which causes variations in the ongoing rainfall, also presumably due to the opposite direction between the monsoon wind and the direction of the main current flowing in the Celebes Sea.

Opis:
The present research work deals with the quantification of toxic heavy metals in the water samples collected from sea water in Międzyzdroje. While the annual average concentration of Cadmium was calculated as 0.44 ppm in 2008 of the year and 0.46 ppm in 2009 of the year. The values obtained were found to be below the permissible limit of 2.0 ppm set for inland surface water. While the annual average concentration of Chromium was calculated as 2.67 ppm in 2008 of the year and 2.64 ppm in 2009 of the year. Which was very much above the permissible limit of 0.1 ppm set for inland surface water. The observed annual average concentration of Copper in the water was 0.08 ppm in 2008 of the year and 0.05 ppm in 2009 of the year, which was below the permissible limit of 3.0 ppm set for inland surface water. While the annual average concentration of Mercury was calculated as 0.05 ppm in 2008 of the year and 0.05 ppm in 2009 of the year, which was very much above the maximum limit of 0.01 ppm set for inland surface water. The annual average concentration of Nickel in the water samples was observed to be 2.47 ppm in 2008 of the year and 2.70 ppm in 2009 of the year, which is close to the limit of 3.0 ppm set for inland surface water. The annual average concentration of Lead in the water samples was observed to be 0.06 ppm in 2008 of the year and 0.05 ppm in 2009 of the year, which is above the permissible limit of 0.1 ppm set for inland surface water. The results of the present investigation indicate that the annual average concentration of Zinc in water samples was 3.45 ppm in 2008 of the year and 3.73 ppm in 2009 of the year, which is above the permissible limit of 5.0 ppm set for inland surface water.

Opis:
The Baltic winter navigation depended always very much on the ice conditions in the sea. The sea ice occurs different in form and amount, depending on the sea area and the winter season. As the maritime traffic on the Baltic Sea constitutes a substantial amount in the whole of the Baltic countries transport, Sea Ice Services (SISs) have come into being. They constituted the Baltic Sea Ice Meeting (BSIM) – a body, which assembles the parties, which are interested in warnings against bad ice conditions, and in protection of navigation in ice in the Baltic Sea. An indispensable co-operator to this body was always the company “Baltic Icebreakers”. To-day within the BSIM operate by the SISs of Denmark, Sweden, Finland, Russia, Estonia, Latvia, Lithuania, Poland and Germany, Netherlands, Norway and the Baltic Icebreakers. The main statutory duties of the SISs is the acquisition, processing and dissemination of actual information on sea ice conditions and on obstructions to navigation due to sea ice. This is done by maintaining observing posts along the coast of those countries, in their ports and approaches to them, by gathering information from ships, from ice beakers, if possible – from reconnaissance flights or satellite images. Routine products of SISs are the ice reports, ice bulletins, ice charts, forecasts and warnings and other information broadcast by mass media, e.g. radio, internet, Navtex and on the national and Baltic SISs’ web sites etc.

Opis:
In this work long-term probability of occurrence of maximum sea levels in some points of Polish Baltic Sea coast, was determined. Use was made of multi-year series of measurement data on maximum yearly sea levels, and their probability distributions were determined. To the analysis Gumbel’s distribution and Pearson distribution of 3rd type as well as quantile methods and the highest credibility method, were applied. Kolmogorov test was used to examine conformity of the theoretical distributions with real random variable distribution. As results from the analysis, the highest sea levels of 1000- year return period can be expected in Polish ports of the west part of the coast , i.e. Kolobrzeg (750, 2 cm , i.e. 2,5 m above the average sea level) and Swinoujscie (723,6 cm) . Lower sea levels of the same return period can be expected in Ustka (720,2 cm), Wladyslawowo (709,7 cm) and Gdansk (716, 7 cm), respectively.

Opis:
Salt is obtained in various regions of the world and using differing technologies. The origin of the salt and its production methods influence its composition, properties and application possibilities. In recent years, sea salt has attracted a lot of interest, as it is commonly believed that it is richer in minerals than pure evaporated salt. One of the oldest methods of extracting edible salt in the world is the evaporation of seawater. Salinas are found in coastal zones of seas and oceans around the world. The salt obtained in the salin is transported to its destination by various means of transport, including sea transport. Taking into account the classification of sea cargo, salt is classified as solid mass cargo, and due to the physicochemical properties of salt, the transport of this product by sea requires security. The aim of this study was to present selected quality parameters of sea salt that are important in its transport and storage. Parameters relevant from the point of view of transport, storage, technology and processing, which are important in shaping the quality of sea salts were compared in salts obtained in various European salinas vs. Himalayan salt. These parameters included water activity, degree of granulation and discharge angle and embankment angle. The paper also presents the characteristics of sea salts from microscopic analysis and an assessment of the correct labeling of the product, which is important for the consumer of the packaged product. In land transport, not only sea salt is transported in bulk, but also the product in commercial packaging, most often weighing 1 kg.

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).

The aim of this paper is to find connections between the digital game Sunless Sea (Failbetter Games, 2015) and Joseph Conrad’s novels, particularly the ones touching on the subject of sea voyage. Sunless Sea is an exploration role-playing game which focuses on the topics of sailors’ loneliness, dual nature of the sea, and above all, player’s inevitable failure. These tropes are shown not only in the narrative structure of the game, but also in its mechanics and design choices. I believe that the game is heavily inspired by the notion of maritime life created by Conrad, as indicated by the quote from The Mirror of the Sea opening the game: “The sea has never been friendly to man. At most it has been the accomplice of human restlessness.”

Opis:
Sea buckthorn (Hippophae rhamnoides L.) is a plant belonging to the Elaeagnaceae family. It is widely distributed throughout Asia, and Europe, especially in colder regions. Generally, sea buckthorn species vary in their phytochemical composition, depending on the climate, and soils in which they grow. Sea buckthorn has been used in traditional medicine for centuries, due to its rich chemical composition. The leaves, fruits, and seeds of this plant are a rich source of bioactive compounds, such as vitamins (A, E, K, C, B1, B2), phenolic compounds (e.g gallic acid, catechin, quercetin, kaempferol), fatty acids (e.g linoleic acid, α-linolenic acid, palmitoleic acid, vaccenic acid), amino acids (e.g glycine, isoleucine, cysteine, tyrosine, histidine, arginine), micro-, and macroelements. The presence of a large number of bioactive compounds results in a broad spectrum of biological activity. It has been shown that sea buckthorn has antioxidant, and anti–inflammatory properties, moreover it protects, and regulates cellular metabolism, has cardioprotective properties, and protective effect on skin cells. Research from recent years offers the hope that sea buckthorn preparations will be used in the treatment of, for example, skin burns, atopic dermatitis or abnormal cholesterol levels, but also as a support for the treatment of, for example, cardiovascular diseases.

This paper describes the application of methodology based on the artificial neural network technique to make short-term wave forecasts. The neural network model is used to predict significant wave height at a selected location on the Baltic Sea based on wave and/or wind data at ten points scattered on the sea. High quality hindcast data were used in the process of developing the forecast methodology. The data originated from the WAM4 wave model. The results show that the neural network technique allowed significant wave height to be predicted accurately. The agreement obtained by a comparison with a testing data set was sufficiently good to confirm the effectiveness of this approach.

Opis:
Short-term measurements of nutrient and DOC concentrations and suspended matter (particles, chlorophyll a, phaeophytin, algae and ATP concentrations) carried out in seawater layers of varying thickness (10, 90, 250 μm and the underwater layer – 15 cm depth) in spring form the basis for a discussion of the diurnal fluctuations of nutrient and suspended organic matter concentrations. Quantitative and qualitative differences in the composition of neuston species were recorded in selected sub-layers of the chemically stratified sea surface microlayer. The non-linear regression equation was applied in a mathematical model of the diurnal fluctuations of nutrients and organic matter. Two maxima and two minima were found in the diurnal cycle of nutrient concentrations and organic suspensions in sub-layers of different thickness selected from the sea surface. The first maximum, expressed by the proliferation of phytoneuston, lasted from the very early morning till mid-morning. The second maximum occurred in the afternoon. The chlorophyll a concentration, and ATP and neuston abundance declined markedly around noon, when the biologically-damaging radiation dose increased, compelling the downward migration of organisms. At the same time, the photo-oxidation of dissolved organic matter intensified and the concentrations of inorganic forms of nitrogen and phosphorus rose. A shift (up to 2 h) between the maximum and minimum neuston concentration in these sea surface layers was indicative of phototaxis occurring within the entire surface microlayer and in the underwater layer. After sunset the decline in phytoneuston abundance could be related to zooplankton grazing as well as to respiratory breakdown.

The nodal tide in the Baltic Sea was studied on the basis of the Stockholm tide-gauge readings for 1825–1984; data from the tide gauge at Świnoujście for the same period provided comparative material. The Stockholm readings are highly accurate and are considered representative of sea levels in the whole Baltic; hence, the final computations were performed for the readings from this particular tide gauge for the period 1888–1980. The tidal amplitude obtained from measurements uncorrected for atmospheric pressure or wind field was compared with that forced only by atmospheric effects. The amplitude of the recorded nodal tide was the same as the equilibrium tide amplitude calculated for Stockholm. Calculations for equilibrium tide amplitudes were also performed for the extreme latitudes of the Baltic basin.

In the recent decade a number of data of different investigations (pollen, diatom, molluscs analysis, lithological investigations, dating by methods of absolute geochronology, etc.) have been collected during the large-scale geological mapping of Lithuanian Maritime region (Lithuanian Coast). The results of investigations confirmed that there were three Littorina Sea transgressions at the Lithuanian Coast: the first manifested approximately in 8500-7800 conventional 14C years BP, the second (maximal) - in 6200-5900 and the third - in 5300-4000 conv. 14C years BP. The Post-Littorina Sea maximum was in about 3600-3400 conv. 14C years BP. The Littorina Sea shoreline displacement curves were carried out. The present-day positions of shorelines of the Littorina Sea as well as other Baltic basins are displaced in different altitudes in separate parts of the Lithuanian Coast due to oscillatory neotectonic movements of Earth crust blocks during Late Glacial and Holocene.

Ecteinascidia thurstoni
Opis:
Ecteinascidia thurstoni is a colonial sea squirt. It has a seasonal rhythm and a tropical and subtropical distribution; it is usually present during the summer months. It synthesizes a group of molecules called ecteinascidins. One of these is ET-743, a compound that has a most original anti-tumoral activity and is today considered to be one of the most promising substances effective against various solid-type tumors (currently sold under the trade name of Yondelis for the treatment of sarcomas and related tumors; it is undergoing phase II/III clinical trails for other kinds of tumors). Worldwide, Ecteinascidia species represent the only available source of this bioactive compound, which was first discovered in E. turbinata. During the present study, the ecology of E. thurstoni along the Suez Canal and Red Sea was investigated. Its populations were observed to be highly gregarious due in part to their low larval dispersal, which is very localized; larvae therefore tend to settle close to their parent colonies. It is only recorded in shallow waters (0.5–1.5 m) as an epiphyte on the pneumatophores of mangroves by the Red Sea, on the pilings of jetties, and the metal or cement banks of the Suez Canal. The morphometric characteristics (zooid length, zooid weight, colony weight) of the Suez Canal population differ significantly from those of the Red Sea. Studying the distribution of this species and locating its different populations along the Suez Canal and Red Sea could help to characterize their genetics, chemistry and bacterial communities at different isolated locations. Ultimately, this will help to define the sources of ET-743 and hence promote its biosynthesis on a commercial scale.

Opis:
This article presents a wider perspective on possibilities of Motorways of the Sea development in the Adriatic Sea, with a special emphasis on the eastern coast of the Adriatic Sea. A complete overview of Motorways of the Sea development has been presented, and key elements influencing the development of Motorways of the Sea were analysed. It has been ascertained that there exist a lot of bottlenecks in the connection to the transport infrastructure in South East Europe. Superannuated port infrastructure, unsuitable inland connections, and nonexistent IT tools for electronic data exchange between all participators in the logistics chain hinder dynamic development of Motorways of the Sea. All these elements were thoroughly analysed, and a proposal for a macro transport strategy suitable for South East Europe has been exposed. It has been accentuated that there is a future for Motorways of the Sea introduction but all described bottlenecks have to be further analysed and removed in a short period of time, to stimulate private sector for financial investments.

Opis:
In the context of short-tenn sea ice forecasting, the model should capture as many of the synoptic features and as much of their variability. as possible. We are interested in the meso-scale properties and processes, i.e. thickness, consolidation, compactness, smoothness, accumulation of ridges, formation of leads and ice edge, drift and displacement, etc. Modelling and forecasting of synoptic ice formation are of interest to shipping as it affects route planning and the operation of icebreakers. With a view to conventional ice charting, the forecast problem might read: Given today 's ice chart, what will tomorrow 's ice chart look like? The model has to return meso-scale features, while essential smaller-scale mechanisms have to be parameterised. The problem in a meso-scale model is to adequately take into account the governing fine-scale mechanisms. Pack ice is a crushable fragmented aggregate, characterized by point-like contacts and stress trajectories. In compressible loading, even local traction forces, causing brittle failure, may be induced. The localization of stress and strain is a considerable complication! By way of localization, critical phenomena at singular points, affect the entire structure. Meaningful characteristics are integrity, state of damage (flaws, cracks). fragmentation and skeletal structure (fabric of fragments, strength of the structure). Structural properties and their evolution dun·ng the material history could be represented by suitably chosen internal variables. To reflect the state of degradation, fragmentation, consolidation, etc., special concepts are required for the damage mechanics of fracturing pieces and fragmented aggregates. Using such a vehicle, the meso-scale mechanics of sea ice could be accommodated in a continuum mechanics model. More elements have been worked out in plasticity.

Opis:
Sea Surface Temperature (SST) maps derived from NOAA weather satellites for the period 1990–2004 were used to investigate seasonal and inter-annual variations in the Baltic Sea. A comparison between monthly mean SST and in situ measurements at the MARNET station ‘Arkona Sea’ showed good agreement with differences in July and August. Monthly means reflect strong seasonal and interannual variations. The yearly means show a slight positive trend with an increase of 0.8 K in 15 years. In particular, summer and autumn months contribute to this positive trend, with stronger trends in the northern than in the southern Baltic. The winters are characterised by a slightly negative trend. The winter minimum SST in the Arkona Sea correlates best with the WIBIX climate index derived for the Baltic region.

Synthesis and New Conception of North Sea Research (SYCON) is the title of a German project carried out from 1998–2000 under the leadership of Hamburg University1. It was accompanied by an international advisory board and covered North Sea issues as well as the general challenges to shelf sea research and sustainable management under global change. Particular emphasis was placed on the interdisciplinary analysis of comprehensive areas of knowledge: the data situation, understanding of processes, model development, instruments and methods, understanding of the system. Based on this, perspectives for future North Sea research were developed. The project produced a synthesis report, eleven monodisciplinary reports and an illustrated brochure for the general public (see Annex 1, this paper, p. 258).

Opis:
Sediments, carbon-datings on seashells, allow us to reconstruct the evolution of the average sea level for some 6000 years on the Taman Peninsula. The current sea level, regionally, appears to be the highest level ever reached on the peninsula. It seems that for the Anapa area and Tchouchtchka Spit area it is possible to propose a sea level curve characterised by a slow, continuous rising during the past 6000 years. On the Taman Peninsula itself, the sedimentary record of this slow ascent has been distorted by a heavy tectonic subsidence. We have identified this neo-tectonic subsidence effect on at least two areas on the peninsula. The south of the peninsula, Burgaz Spit and Vityazevos Lagoon, is the most affected area. The Taman Gulf is an intermediate area. The tectonic subsidence is particularly noticeable from 1500 to 500 BC, which we believe to have been misinterpreted until now, and to be at the origin of the notion of "Phanagorian Regression".

Opis:
Maritime tourism should be understood not only as a system of fixed, maritime links and attractive cruises but also as individual yacht cruises, and many other forms of spending time on the water or under the water. A special type of tourism is maritime tourism, which includes features such as recreational fishing in the sea. Sport and recreational fishing became popular in Poland in the 90’s of last century. According to the data of harbor masters that keep records of fishing vessels out in the sea, the first effective service providers were the skippers from Łeba and Darłowo. The following study presents the development of specialized tourism in Poland which is fishing tourism with particular emphasis on Darłowo. Rules for organizing fishing trips, and the conditions that must be met in order to start this kind of business were discussed. Another important issues in the article include preparations of individual units for realizing tourist function, presenting additional services provided by the organizers of fishing cruises. On the basis of the survey research, the characteristic of fishing service users has been prepared, taking into account: motives and forms of arrivals, territorial origin of tourists, accommodation and length of stay.
W niniejszym opracowaniu przedstawiono rozwój morskiej turystyki wędkarskiej w strefie Środkowego Wybrzeża na przykładzie portu w Darłowie. Zaznaczyć należy, że morska turystyka wędkarska staje się aktywną formą wypoczynku, zyskując coraz większe zainteresowanie nie tylko wśród wędkarzy, ale także pośród osób bez wcześniejszego kontaktu z wędkowaniem. W artykule na podstawie bezpośrednich badań terenowych prowadzonych w Darłowie przedstawiono zasady organizacji rejsów wędkarskich oraz wskazano na dodatkowe usługi świadczone podczas pobytu. Szczegółowo omówiono ponadto elementy składowe popytu turystycznego na rejsy wędkarskie. Uwzględniono więc liczbę korzystających z rejsów wędkarskich, dokonano ich charakterystyki społeczno-demograficznej, wskazano na motywy przyjazdów i obszary, z których pochodzili. Podkreślić należy, że rozwój wędkarstwa morskiego w Polsce uległ ożywieniu w drugiej połowie lat dziewięćdziesiątych. Świadczyć może o tym rosnąca liczba wędkujących i wypraw wędkarskich. Jak wynika z prowadzonych badań, Darłowo obok Łeby i Władysławowa staje się ważnym ośrodkiem rozwoju morskiej turystyki wędkarskiej. W Darłowie duży udział w organizacji i rozwoju bazy infrastrukturalnej dla wędkarstwa morskiego miała Darłowska Lokalna Grupa Rybacka. Jest to stowarzyszenie, które wspiera rozwój obszarów rybackich oraz łagodzi skutki zmian strukturalnych w sektorze rybołówstwa m.in. poprzez wsparcie finansowe zakupu nowych kutrów czy jachtów lub ich przystosowanie na potrzeby wędkarstwa morskiego. Interesujące pozostają wyniki badań ankietowych, które pozwoliły stworzyć wizerunek korzystających z morskiej turystyki wędkarskiej w Darłowie. Głównym motywem przyjazdu była chęć wypoczynku i relaksu (45,0% ogółu ankietowanych) oraz atrakcyjna oferta wędkarska (28,0%), o której wędkujący dowiedzieli się z witryn internetowych. Na rejsy wędkarskie dominująca grupa ankietowanych przyjechała własnym samochodem, na pobyt trwający od 1 do 6 dni. Korzystali oni głównie z bazy noclegowej oferowanej przez organizatorów rejsów (20,0%), z miejsc noclegowych na kwaterach prywatnych (23,0%) i w ośrodkach wczasowych (25,0%). Uczestnicy rejsów wędkarskich pochodzili z miast regionu środkowopomorskiego oraz z całego kraju, przede wszystkim z województw: dolnośląskiego, mazowieckiego, śląskiego i wielkopolskiego. Wyniki przeprowadzonych badań jednoznacznie wskazują, że morska turystyka wędkarska staje się perspektywicznym stymulatorem rozwoju turystyki i czynnikiem aktywizacji społeczno-gospodarczej miast i gmin nadmorskich w Polsce.

Opis:
W artykule omówiony został problem zdarzeń wypadkowych na morzu. Mimo znaczących postępów w technologii budowy i wyposażania statków, wraz ze wzrostem ilości ładunków i pasażerów przewożonych drogą morską, rośnie liczba wypadków, w tym związanych ze śmiercią członków załóg i pasażerów. Na podstawie opracowań instytucji międzynarodowych zajmujących się bezpieczeństwem transportu morskiego, autor wskazał własne spostrzeżenia oraz uwagi. Pod względem zagrożenia wypadkowego, transport morski sytuuje się jako jeden z bardziej niebezpiecznych dla ludzi, statków, ładunku i środowiska. Oznacza to, że należy poszukiwać sposobów poprawy sytuacji, a obecne sposoby uznać za niewystarczające. Wskazano główne przyczyny zdarzeń wypadkowych na morzu oraz sugestie sposobów poprawy bezpieczeństwa w transporcie morskim.
Paper discussed the problem of accidents at sea. Despite the meaningful development in shipbuilding technology and ship equipment, together with the cargo and passenger transport growth by sea, the number of marine accidents are still increasing with accompanying them the lives lost of crew and passengers. On the basis of international institutions’ reports being concerned with the marine transport safety the author indicates own observations and remarks. In respect of accident menace the transport by sea seems as one of more dangerous means for people, ships and environment. It means it ought to find out the ways of bettering the situation and present methods to recognize as unsatisfactory. It was indicated the main reasons of accidents at sea and suggestions of improving the safety in marine transport.

Opis:
Hydrographic data from the North Aegean Sea were used to examine the summer variability of surface water masses during the period 1998–2001. Attention was placed on the surface hydrographic features of the area, such as the Black Sea Water (BSW) plume expansion, the frontal characteristics of the BSW with the Levantine Intermediate Water (LIW) and the variability of submesoscale hydrographic features (such as the Samothraki Anticyclone). Strong southerly wind stresses were found responsible for relaxing the horizontal density gradients across the BSW-LIW frontal zone and displacing this front to the north of Lemnos Island, thus suppressing the Samothraki Anticyclone towards the Thracian Sea continental shelf. Under northerly winds, the BSW-LIWfront returns to its regular position (south of Lemnos Island), thus allowing the horizontal expansion of the Samothraki gyre up to the Athos Peninsula. Present results indicate the importance of medium-term wind stress effects on the generation of Samothraki Anticyclone suppression/expansion events.

Opis:
Industry, still one of the most significant sectors of the economy, is undergoing permanent quantitative and qualitative changes. Therefore it should be the subject of not only business analyses, but also research which more broadly explain our reality in the environmental, social and economic dimensions, noting the more and more complex relations between the elements, sets and even entire systems functioning in various spatial arrangements. The research on the changes in industry structures implemented by Polish researchers representing various fields of science has been an essential element of the cognitive process for many years. Among them are also geographers for whom the spatial aspects (the characteristics and issues) of industrial activity seem particularly significant. However, the issues handled by them mostly regard land areas. Therefore, there is also a strong need for wide-range theoretical and applicable research on the identification of sea and coastal areas functioning on the basis of diversified industrial structures, using the previous academic achievements, including the achievements of the Polish economic sea geography.

Opis:
Statistical studies of marine accidents and unfortunate events in ice-covered areas in 1995-2004 and 2004-2011 showed a general lack of information from the area under the jurisdiction of the Russian Federation. The author’s research for the period 2004–2011 showed a large number of unfortunate events caused by lack of adequate provision of nautical charts, shortage of accurate position systems on board vessels as well as weak technical condition of these vessels. The author examined the problem of navigation safety on the Northern Sea Route in terms of availability of the official nautical charts and publications. The availability of official nautical publications supplied by global producers is more diverse and ambiguous than it is in case of nautical charts. Surprising is lack of Russian publications related to tides and unavailability of a guide for planning routes on Northern Sea Route issued by Russia in Russian and English languages. Global producers of official charts and nautical publications do not provide full range of information and recommend vessels the use of the products supplied by Russia. These products are issued in Russian. This is a serious impediment to their use and thus introduces privilege of ships’ crews who speak Russian. Northern Sea Route leads through regions that are not sufficiently explored. The Northern Sea Route Administration recommends guiding ships only on designated routes marked on maps and described in nautical publications. The currently hydrographic work is focused on determining new routes according to the spatial distribution of the ice massifs during the navigation season. However, this does not solve the problem of a comprehensive exploration of the Russian Arctic regions for the purpose of safe navigation on the customized routes.

Opis:
In this paper, parametric rolling is divided into 5 heavy grades, establishing a classification for parametric rolling. This is achieved by a multi-parameter application in the simulations. For this purpose, parametric rolling, established criteria and the state of the art are considered and the results are summarized. Based on this, parametric rolling is successfully simulated using discrete simulation in MARIN [1]. Five heavy grades are introduced so different classes of parametric rolling can be distinguished. Furthermore, dependencies and probabilities for the occurrence of parametric roles in relation to the see are determined numerically. This will later be used in an assistance system on board ships to compute the prediction of parametric roll using an AI.

Opis:
The aim of the paper was to confirm the proposition that the classical SST algorithms MCSST and NLSST originally prepared for AVHRR data could also be used for Meteosat/SEVIRI data with satisfactory accuracy in the mid-latitude region, where the spatial resolution is about 7×7 km. The research was performed in the southern Baltic Sea (between 13◦E 53◦N and 21◦E 58◦N). Data were collected in all the seasons of 2007. The coefficients were found by means of regression analysis. SSTs determined on the basis of AVHRR data were used in the regression analysis instead of in situ data. A set of paired AVHRR and SEVIRI images spaced no more than 8 minutes apart were compared. The results show that the method is capable of producing sea surface temperatures with a statistical error (standard deviation) of 1◦C.

Opis:
Observed basic meteorological quantities, heat and radiation fluxes from three different measurement stations in the Baltic Sea are compared with model data of the coupled sea-ice-ocean model BSIOM in order to evaluate the atmospheric forcing, corresponding surface fluxes and the sea surface response. Observational data weremade available from the BASIS winter campaigns in 1998 and 2001 as well as from the r/v ‘Alkor’ cruise in June 2001. Simulated fluxes were calculated from prescribed atmospheric forcing provided from the SMHI meteorological database and modelled sea surface temperatures. The comparison of these fluxes with observations demonstrates a strong correlation, even though mean differences in sensible heat fluxes range from 4 to 12 W m−2 in winter and −25 W m−2 in the June experiment. Differences in latent heat fluxes range from −10 to 23 W m−2. The short-wave radiation flux used as model forcing is on average 15 W m−2 less than the corresponding observations for the winter experiments and 40 W m−2 for the June experiment. Differences in net long-wave radiation fluxes range from −5 to 12W m−2 in winter and −62W m−2 for the June experiment. The correspondence between measured and calculated momentum fluxes is very high, which confirms the usability of our model component for calculating surface winds and wind stresses from the atmospheric surface pressure.

Opis:
The response of semi-realistic wind speed increase scenarios to the mean sea level and current regime of semi-enclosed sub-basins in the Baltic Sea is studied with a 2D hydrodynamic model. According to the model output of spatial mean sea levels, an increase in the westerly wind component by 2 m s−1 leads, for example, to a mean sea level rise of up to 3 cm in windward locations in the study area. The sea level change patterns depend on the wind scenario and coastline configuration. The increases in wind speed considered here also lead to enhanced water exchange through the straits, strengthening of the basin-scale circulation, enhancement of up- and downwelling, and increased bottom stresses near coasts.

Opis:
Santos Port is located in Brazilian coast, in an estuarine area inside Santos Bay named Baixada Santista. The currents behavior is forced by tides. The resulting tidal level variability (high tide, mean sea level and low tide) recorded from Santos Dock Company tide gauge (1940 to 2014) shows a consistent increasing trend. The estimation about the magnitude of mean sea level rise (MSLR) in recommendations, guidelines or requirements issued by different countries and agencies from 1990 provide examples of different approaches used around the world in comparison with the local trends obtained for Santos Port. It is concluded that MSLR will have a considerable impact upon the port and adjacent areas, with approximately 1.0 m rise estimated from 1990 to 2100. Baixada Santista is a lowland situated a few meters upper from the sea level and some areas are possible to be submerged in the end of this century. Not only the wetlands of mangroves will be affected, but also the infrastructures, residential zones and the port will face problems. The major SLR impacts upon port operation will be the reduction of freeboard of the quays, flooding of storage yards (and other low storage areas) and of the internal transport tracks or rails. Also the increasing sedimentation in the nautical areas of access channels, turning basins and berths, will induce more maintenance dredging.

Opis:
Development of the river sea transport is directly related to the characteristics of waterway network which enables navigation between river basins and seas. Inland waterways in Serbia belong to the Danube navigational system. There are two navigational directions: Danube East and Danube West. River-sea transport can be directly established in these directions between the Serbian international ports on the Danube (Apatin, Novi Sad, Belgrade, Pan?evo, Smederevo and Prahovo). Development of the Pan-European Corridor VII and the River Danube-Black Sea and Danube-Rhine-Main region would allow not only in Serbia but also in neighbouring states and all over Europe connection with the sea. In this paper the technical and exploitation characteristics of the river Danube will be analysed in terms of the navigation of various river and sea vessels with different exploitation characteristics.

Opis:
Climate Research of the globe is a current task, in particular to confirm the general hypothesis of global warming associated with an increase in average temperature. The sea acoustic climate is derived from the concept of climate and refers to the conditions of propagation of acoustic waves in a particular basin. In this paper, the results of systematic measurements of temperature, salinity and velocity distributions of sound in the area of the southern Baltic will be present. The focus will be on the results of extensive measurements carried out „in situ” in particular.

Opis:
One of the fundamental states of the sea surface is its heave. Despite of years of the intense scientific inquiry, no clear understanding of the influence of this aspect on the dynamics of the sea environment has emerged. The separation of two nearby fluid elements which one may observed for example as a free floating of small objects on the sea surface (rescuers on the rough sea or small research vessels) is caused by the interaction of different components. On the other hand one may say that the heave of the sea is also a summary interaction of a few components describing the dynamics of the sea. Therefore it is the most important aspect, which influenced the dispersion phenomenon. This observation has important consequences for many different problems as for example conducting Search and Rescue missions and using unmanned ships. We would like to present results of our experiment focused on finding the answer to question about nature of the heave of the sea and its influence on safety of Unmanned Surface Vessels (USV).
