Opis:

One of the crucial systems of sea mining ship for poly-metallic concretions is its motion control system (SMC). Power of such system depends on sea environment characteristics and main dimensions of the ship. It can be expected that it will have important influence on total power of the ship’s power plant and in effect on the mining ship’s dimensions. In this paper is presented one of the possible ways of preliminary estimation of design power of SMC system for sea mining ship. Since details of design solution of such system for the ship in question are unknown (ships of the kind have not been built so far) the presented results should be considered to be the first estimation of the order of the power demand.

Opis:

Due to the complexity of the marine environment, in deep-sea drilling, all kinds of strings are corroded by different deepsea conditions for a long time, accompanied by high temperature and high pressure, which lead to the continuous change of mechanical properties of materials. In order to solve the problem that the material mechanical parameters cannot be accurately described in the performance analysis of the casing, deep-sea simulated corrosion and material damage experiments of P110 material were carried out in this paper. Mass loss and tensile experiments on corrosion-damaged test pieces were conducted under different corrosion experimental periods. The changes in mechanical properties of the material were analyzed. Equations of the variation of the equivalent yield strength and the equivalent tensile strength were obtained. The results show that the equivalent yield strength and the equivalent tensile strength decrease with the increase of the weight loss rate. Based on the experimental results and finite element analysis, a method for establishing the material corrosion model was proposed in this paper. The deep-sea drilling corrosion performance model of P110 material was established, which greatly reduced the error caused by the material uniformity assumption in finite element analysis. This paper provides a theoretical basis for the analysis of reliability and life of P110 materials in wells.

Opis:

The paper discusses the scattering of radiation by a Baltic crude oil –sea water emulsion. The scattering spectrum calculated using the Mie solution in the spectral range from 380 nm to 730 nm is compared with the measured spectrum of light scattered through a right angle. Spectra in the wavelength range from 210 nm to 730 nm were measured using a spectrofluorimeter for fresh and stored samples of the Baltic crude oil emulsion. Scattering increases with wavelength in the UV range and then decreases slightly with the wavelength of visible light. The result of the calculation is similar to the measured spectra. Both the calculated and measured spectra display numerous relative extremes throughout the spectral area. Light scattering in the emulsion decreases during storage as the oil concentration in the medium diminishes. The results also demonstrate that the single scattering model describes the phenomenon correctly.

Opis:

To examine the distribution of Trichodesmium relative to physicochemical factors during summer in the Changjiang (Yangtze River) Estuary and adjacent East China Sea shelf, three cruises were conducted separately in June 2009, July 2011, and August 2009. Trichodesmium species found were T. thiebautii, T. erythraeum, and T. hildebrandtii. The population was dominated by T. thiebautii, which accounted for >85% of the samples found. Most of them were free trichomes. Colonial forms were rarely observed (approximately 10% of our samples), occurring only in offshore waters. The depth integrated abundances of Trichodesmium were 308 × 103, 1709 × 103, and 3448 × 103 trichomes m−2 in June, July, and August, respectively. Trichodesmium was distributed abundantly in the southern or southeastern part of our study area, where nutrients were low and light penetration, temperature, and salinity were high, which were influenced by the Taiwan Warm Current (TWC) and Kuroshio. Trichodesmium was found in low abundance in inshore, eutrophic, low-salinity waters, which were mainly controlled by the Changjiang Diluted Water (CDW) and coastal current. These results suggest that spatiotemporal changes in the summer Trichodesmium distribution correlate highly with the variations in physicochemical properties that are primarily controlled by the TWC, Kuroshio, and CDW. The summer N2 fixation rate of Trichodesmium was estimated at 12.3 μmol N m−2 d−1 in our study area, contributing >50% of biological N2 fixation.

The antimicrobial activity of twelve preparations of humic substances isolated from sea water, marine bottom sediments and lake water was examined. Humic substances from marine bottom sediment samples were fractionated into humic and/or fulvic acids. The susceptibility of 11 strains of anaerobic, 8str ains of aerobic bacteria and 2 strains of yeast-like fungi to preparations of humic substances, humic and/or fulvic acids was determined employing the plate dilution technique in Brucella agar (anaerobic bacteria), Mueller-Hinton agar (aerobic bacteria) and Sabouraud agar (yeast-like fungi). Concentrations from 150 to 600 μg ml−1 of the preparations examined inhibited the growth of numerous microorganisms (Table). The results obtained seem to indicate that humic substances are involved in the self-purification of sea and lake waters.

Opis:

The Indian marine environment supports employment for over 200 million people, including revenue of nearly $7 billion per annum. However, ecological goods and services of the shallow coast and the marine environment of the Indian peninsula are being affected by recurrent blooms of microalgae. One hundred and six published literature, starting from the first report in 1908 to 2017, were reviewed to investigate the historical occurrences of marine microalgal blooms (MMBs) around the Indian peninsula. 154 MMBs comprising 24 genera and 7 classes were reported during the study period. Noctiluca (dinophyceae) and Trichodesmium (cyanophyceae) bloom contributed 34.4% and 31.8% of total blooms. PCA revealed that high sea surface temperature (SST) and salinity were significant driving forces for Trichodesmium blooms formation, while high nutrients (NO3-N, PO4-P, and SiO4-Si) and low salinity triggered prymnesiophyceae, raphidophyceae, bacillariophyceae and most of the dinophyceae blooms. Noctiluca blooms were linked with both eutrophication and the abundance of prey organisms. HABs were generally dinophyceae dominated and were associated with mass mortality of aquatic fauna, human intoxication, paralytic, and ciguatera shellfish poisoning and even death. Increasing SST and anthropogenic influences around the Indian peninsula could increase the occurrences of MMBs (including HABs) and the number of causative taxa. Proper safety measures such as routine monitoring of phycotoxin levels in the environment and local seafood are required to be put in place in other to protect the health of the public.

Opis:

The article’s purpose is the multidimensional analysis of the evolution of Australia and India’s maritime policies and their impact on the endeavors to develop their maritime cooperation in the 21st century. Two research questions are to be answered in that connection: what changes and why India and Australia introduced to enhance their maritime security doctrines in the 21st century and why those changes contributed to the more in-depth cooperation in the second decade of the 21st century. The hypothesis based on those questions argues that not only the rise of China but also global processes in maritime affairs - such as the growing number of state and non-state actors, as well as the interdependence between the fields of human activities at sea - pushed the littorals like India and Australia to turn their maritime strength from coastal to oceanic and convinced them too to cooperate. That process was accompanied by the convergence of the security perceptions by both countries (India and Australia) and the mutual understanding of common interests in all the elements of modern maritime security. The Christian Bueger’s matrix serves as an explanatory framework to highlight the dynamics and broader context of the changes in India and Australia’s maritime security doctrines in the 21st century. It provides the conceptual framework for explaining closer cooperation between these two countries. The article analyzes India and Australia’s maritime strategies, focusing on four variables from Bueger’s matrix: national security, economic development, marine environment, and human security. In those dependent variables, particular elements of their activities serving as sub-variables are highlighted: in national security - shaping the seapower; in economic development - Illegal, Unreported, and Unregulated (IUU) fishing; in the marine environment - climate change mitigation; in human security - the fight against piracy and human trafficking. The choice of the mentioned elements is justified by their role in Australia and India’s activities within maritime strategies and their influence on other elements of the maritime security matrix. The article starts with a description of Bueger’s matrix in the context of the evolution of the maritime security concept in international relations. The second part outlines the centrality of the Indian Ocean in Indian and Australian modern military and economic security. The third part explores and explains the roots of Indian maritime security thinking, and the fourth investigates the evolution in Australia’s attitude toward maritime affairs. The final part presents the developments in Indo-Australian bilateral cooperation in the 21st century.

Opis:

Silicon is a major nutrient for siliceous primary producers, which can become a potential limiting nutrient in oligotrophic areas. Most of the silicon inputs to the marine environment come from continental discharges, from both superficial and ground waters. This study analyses the main sources of silicon and their dynamics along the southernmost 43 km of shoreline in the Gulf of Valencia (Western Mediterranean Sea). The salinity and silicate concentration in the different compartments (springs, freshwater wells, beach groundwater, surf zone and coastal waters) in this coastal area were determined. In addition, chlorophyll a and phytoplankton community were analyzed in the surf zone and coastal waters. Silicate concentrations in freshwater wells ranged between 130 and 150 μM, whereas concentrations of this nutrient declined to 49 μM in freshwater–seawater mixture transects. At the same time, there was a positive gradient in silicate for both freshwater and coastal waters southward. An amount of 18.7 t of dissolved silicate was estimated in the nearest first kilometre nearest to the coastline, 6 t of this silicate belonged to the background sea level. On the other hand, the sum of the main rivers in the area supplies 1.6 t of dissolved silicate per day. This implies that a large amount of the remaining 11.1 t must derive from submarine groundwater discharges, which would thus represent 59% of the coastal dissolved silicate budget. Overall, it is suggested that a subterranean transport pathway must contribute considerably to silicate concentrations throughout this zone, which is characterized as permeable.

Opis:

Bacterial production, primary production and a number of other environmental factors were measured during six cruises in the Gulf of Gdańsk conducted in various seasons from 1995 to 2001. Bacterial production (BP) in the epipelagic layer ranged from 1.5% (April) to 80% (July) of the gross primary production (PP). Significant differences were observed between the BP/PP ratios in estuarine and open-water areas. The highest values were recorded in the coastal area and near the mouth of the river Vistula. It suggests that allochthonous organic matter has a great influence on BP. The correlations between particular parameters and regression analyses indicated that BP in the Gulf of Gdańsk depended on temperature, organic nitrogen concentration, PP, chlorophyll a concentration, organic phosphorus concentration, salinity and biochemical oxygen demand. Of all the independent variables, the temperature had the greatest impact on BP (R2 = 0.62). There was an inverse parabolic relationship between bacterial production and temperature. It appears that above a temperature of 12◦C bacterial production depended on substrates to a higher degree than on temperature. The negative correlation between BP and concentrations of mineral nitrogen and phosphorus in the annual cycle were probably due to an indirect dependence. A multiple regression equation, which included temperature and organic phosphorus concentrations, explained 78% of the variation in BP. Increasing BP resulted in an increasing biomass of bacterivorous nanoflagellates and of bacterivorous ciliates, which is indicative of bottom-up control in this segment of the trophic chain.

Opis:

The aim of the article is the identification of components of maritime governance and evolution of the concept of maritime governance in contemporary International Relations. The main research questions are: what elements constitute the structure of maritime governance and why the role of maritime governance is increasing in the policy of super and regional powers. The answer to these questions will be used to verify the adopted hypothesis which indicates that maritime governance is a dynamic process consisting of interdependent areas of legal regulations, blue economy, security and environmental elements. Their horizontal and vertical interdependence and interrelation while dealing with oceans make maritime governance necessary instrument for super and regional powers to attain their interests. Based on the presented assumptions and purpose, the following structure of the article was adopted. The introduction highlights the role of oceans in the world affairs and presents research questions and hypothesis. In the second part of the article main stages of discourse on maritime governance are discussed and characterized, putting emphasis on the process of shaping its conceptual and terminological framework. Methodological differences and similarities in defining maritime governance are explored. The third part indicates the operational dimension of the concept of maritime governance, presenting the stages of the process of institutionalization of maritime cooperation between states. Finally, the case study of the Integrated Maritime Policy of the European Union is presented to serve as an exemplification of the modern maritime governance. The conclusion of the article contains answers to the research questions posed.

Opis:

The paper describes the modelling ofeg g production in Acartia spp. under changing environmental conditions in the southern Baltic Sea (Gdańsk Deep). The hypothesis (Sekiguchi et al. 1980) that the food-saturated rate of egg matter production is equivalent to specific growth rate ofco pepods is applied. The average number ofeggs produced per day by one Acartia female is obtained as a function ofg rowth rate, i.e. by multiplying exp gN3 − 1 from the growth rate of the nauplius stage equation by Wfemale/Wegg. The copepod model, reduced to a zerodimensional population model calibrated for Acartia spp. under the environmental conditions typical ofthe southern Baltic Sea, was used to determine the effects of temperature and food concentration on the growth rate ofeac h oft he model stages (see Part 1 – Dzierzbicka-Głowacka et al. 2009 – this issue). In this part, egg production as a function of the above parameters is evaluated. The rate of reproduction during the seasons in the upper layer ofthe Gdańsk Deep is also determined.

Opis:

Trophic models of the micro and meiobenthic community of six sandy beaches on the Ligurian coast (north-western Mediterranean Sea) have been performed to assess variations in structure and function of the ecosystem. A novel approach based on the determination of the feeding predisposition of the benthic community revealed that there is a significant shift in the trophodynamics of the system with respect to environmental constraints. Along an emerged-submerged gradient the benthic community displayed a clear trend from a fundamentally detritusdependent structure to an autotrophic, more balanced and diversified one. The trends analysed focus on the importance of the swash zone as a transitional area between the land and the sea that is characterised by a high diversity and activity of the trophic network.

Opis:

In this paper, a new multi-step approach for the selection of an LNG terminal location (for offshore terminal, onshore terminal, or floating storage regasification unit – FSRU) was presented based on the holistic evaluation of the impacts of the potential LNG terminal. The first step was to divide the entire observed area of the Adriatic Sea of the Republic of Croatia into smaller areas by using the geographic information system (GIS) and then selecting areas where the installation of an LNG terminal was technically feasible based on the pre-elimination criteria. Potential LNG terminal areas were selected by taking into account all pre-elimination criteria, and 14 areas were selected by using pre-elimination criteria in a GIS smart chart tool that enabled the analysis of spatial data. The second step involved analyzing the elimination criteria of the 14 areas selected in the first step by pre-elimination criteria analyses. Six potential LNG terminal micro-locations were selected based on the defined elimination criteria. In the third step, these six micro-locations were evaluated by experts by using 38 specific sub-criteria classified into five distinct groups: economic (11 sub-criteria), ecological (13 sub-criteria), safety (4 sub-criteria), traffic connection (6 sub-criteria), and gas needs (4 sub-criteria). The fourth step involved making a multi-criteria expert analysis of the six locations selected in the previous step (for onshore terminals, offshore terminals, and FSRU) for the analysis of three different scenarios by the PROMETHEE (Preference Ranking Organization METhod of Enrichment Evaluation) method. In every scenario, one group of sub-criteria was selected as the most important according to its cumulative relationship with the other groups of criteria (scenario 1 – economic group; scenario 2 – ecological group; scenario 3 – safety group). A different importance (weight) was given to each of the sub-criteria. The methodology presented in this paper can also be used for decision-making processes for other marine and coastal activities, where incorporating an ecosystem approach is necessary for taking into account safety and project costs; however, the selection of pre-elimination criteria, elimination criteria, and sub-criteria should be carefully adjusted to other situations or activities.

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.

The round goby (Neogobius melanostomus) is a non-indigenous species in the Baltic Sea, introduced to its waters (the Gulf of Gdańsk) from the Black, Azov, and Caspian Seas. For this reason, an attempt was made to determine the species' parasitic fauna in its new environment. Within 1994-2000, a total of 201 round goby specimens caught in the Gulf of Gdańsk were examined. The parasites found represented protozoans (Trichodina domerguei domerguei), digencans (Diplostomum spp. metacercariae), cestodes (Bothriocephalus scorpii, plerocercoids), nematodes (Hysterothylacium aduncum L₃, L₄, and adults), and canthocephalans (Echinorhynchus gadi and Pomphorhynchus laevis). The parasitic species found are common in the Gulf of Gdańsk. It should be emphasized that, since the round goby has only recently appeared in the Gulf, the parasitic fauna of this fish is not yet complete.

Opis:

The aim of the study was to analyse the balance of mercury (Hg), i.e. the content of this metal, its inflow and outflow, in the ecosystem of the Bay of Puck. Based on literature data and the results of the author’s own study, this analysis has shown that the main source of Hg pollution is the atmosphere. An estimated 1.1–3.8 kg of Hg enters annually from the atmosphere, whereas the mass of Hg carried there by river waters per annum is about 7 times lower (0.13–0.44 kg year−1). The 0.9 –2.7 kg year−1 of Hg released from Bay of Puck waters to the atmosphere is of the same order as the quantity deposited from the atmosphere. The total amount of Hg deposited in the upper (0–5 cm deep) layer of the sediments has been estimated at 240–320 kg, its rate of entry being c. 2.25–2.81 kg year−1. 0.25–1.25 kg year−1 of Hg are released from the bottom sediments to bulk water, while 0.61–0.97 kg remains confined in aquatic organisms, including 133 g in the phytobenthos, 2.6 g in the zooplankton, 420–781 g in the macrozoobenthos and 34 g in fish.

Opis:

Svalbard archipelago, a high latitude area in a region undergoing rapid climate change, is relatively easily accessible for field research. This makes the fjords of Spitsbergen, its largest island, some of the best studied Arctic coastal areas. This paper aims at answering the question of how climatically diverse the fjords are, and how representative they are for the expected future Arctic diminishing range of seasonal sea-ice. This study uses a meteorological reanalysis, sea surface temperature climatology, and the results of a recent one-year meteorological campaign in Spitsbergen to determine the seasonal differences between different Spitsbergen fjords, as well as the sea water temperature and ice ranges around Svalbard in recent years. The results show that Spitsbergen fjords have diverse seasonal patterns of air temperature due to differences in the SST of the adjacent ocean, and different cloudiness. The sea water temperatures and ice concentrations around Svalbard in recent years are similar to what is expected most of the Arctic coastal areas in the second half of this century. This makes Spitsbergen a unique field study model of the conditions expected in future warmer High Arctic.

Opis:

From a data set of observations of Suspended Particulate Matter (SPM) concentration, Turbidity in Formazin Turbidity Unit (FTU) and fluorescence-derived chlorophyll-a at a mooring station in Liverpool Bay, in the Irish Sea, we investigate the seasonal variation of the SPM: Turbidity ratio. This ratio changes from a value of around 1 in winter (minimum in January— February) to 2 in summer (maximum in May—June). This seasonal change can be understood in terms of the cycle of turbulence and of the phytoplankton population that affects the nature, shape and size of the particles responsible for the Turbidity. The data suggest a direct effect of phytoplankton on the SPM:Turbidity ratio during the spring bloom occurring in April and May and a delayed effect, likely due to aggregation of particles, in July and August. Based on the hypothesis that only SPM concentration varies, but not the mass-specific backscattering coefficient of particles bbp *, semi-analytical algorithms aiming at retrieving SPM from satellite radiance ignore the seasonal variability of bbp * which is likely to be inversely correlated to the SPM:Turbidity ratio. A simple sinusoidal modulation of the relationship between Turbidity and SPM with time helps to correct this effect at the location of the mooring. Without applying a seasonal modulation to bbp *, there is an underestimation of SPM in summer by the Ifremer semi-analytical algorithm (Gohin et al., 2015) we tested. SPM derived from this algorithm, as expected from any semi-analytical algorithm, appears to be more related to in situ Turbidity than to in situ SPM throughout the year.

Opis:

This study was carried out to determine the water quality of the beaches at Matrouh, south-eastern Mediterranean Sea, Egypt, by studying environmental variables as well as phytoplankton abundance and community structure. Surface water samples were monitored from a series of beach sites over a period of five seasons during 2009–2010. A total of 203 phytoplankton species were identified from seven algal divisions. Seasonal differences in the quantitative and qualitative composition of the phytoplankton communities in the different sites were marked. Nutrient concentrations and phytoplankton abundances were found to be poorer than those of many other areas along Egyptian coast. The Shannon-Wiener Diversity Index classified Matrouh water as being between clean and moderately polluted, whereas the WQI demonstrated that it was between good and excellent. It can be concluded that the index based onWQI is currently more suitable than the phytoplankton species index for assessing the quality of the water of the Matrouh beaches.

Opis:

Measurement of pCO2 in highly dynamic coastal zones such as the southern Baltic Sea presents many challenges. In this study, we designed a system to measure pCO2 and then validated it in a series of laboratory and seagoing tests. The fast response time of the system was shown to provide a better resolution of CO2 system gradients. In the open waters of the Baltic Sea, the accuracy of the pCO2 measurements (±1.3 μatm) met the requirements of the ICOS (±2.0 μatm). In the coastal zone, there was less consistency between pCO2, DIC and pH measurements, suggesting the need to redefine the quality assurance and control requirements for the measurement of pCO2 in dynamic regions.

Opis:

The economical development of the world is based on transportation system. More than half of the products transported all over the world are carried by sea. Sea transportation is made with different kind of ships, as bulk carriers, cargo vessels, container ships, tankers. Ships are managed by people. In group or as individual, anybody can make errors. In maritime area these errors have as results accidents and disasters. Many of these events affect especially the environment. As 80% of necessary petroleum products are transported by sea, the risk of a major environment disaster caused by human errors is high. Anyway, over 99% of petroleum cargo transported by sea is carried without incidents. This paper presents the effects of human errors, mostly cases that involved tankers, which were produced in the navigation and operational processes.

Opis:

The Baltic Sea covers an area of 415 000 km2. A typical brackish sea, it is very sensitive to anthropogenic activities. Inorganic nutrients, trace metals, chlorinated hydrocarbons and crude oil products are contaminants studied in the Baltic Monitoring Programme of HELCOM. The data collected by the riparian countries forms the basis for the periodic assessments of the state of the marine environment of the Baltic Sea Area produced by HELCOM every five years. Since 1992 marine nature conservation has been part of the HELCOM convention. According to the third status report issued in 1996, it was the first time that HELCOM could strike a positive balance with regard to the decreasing environmental load. This is also reflected in lower concentrations of harmful substances in fish, marine mammals and seabirds in the Baltic Sea Area. The reasons for this progress are the protective actions initiated by HELCOM and the economic collapse in some of the former East Bloc countries, the latter resulting in an abrupt fall in industrial and agricultural production. Although the restoration of the Baltic ecosystem has only just begun, the protective measures introduced to achieve this aim can serve as an example of how to solve similar problems in other semi-enclosed basins and shelf seas.

Opis:

A medium-sized inflow (about 200 km3 according to IOW data, – personal communication) of saline water into the southern Baltic Sea occurred during January 2003. Unlike any previously observed inflow, this one brought very cold water, of temperatures around 1–2◦C and less. Since the temperature of the deep water in the southern Baltic before the inflow was exceptionally high (11–12◦C), the inflowing waters produced dramatic changes and a steep temperature gradient. The movement of the inflowing waters through the deep basins and channels of the Baltic Sea from the Arkona Basin to the Gdańsk Deep during next 4–8 months is described. Frequent mesoscale structures and intensive mixing followed the eastward transport of the inflow water, particularly in the Bornholm Deep and Słupsk Furrow. The present paper is based on data collected during of 6 cruises r/v ‘Oceania’ between December 2002 and August 2003. The last cruise in August took place in order to assess the long-term consequences of the inflow.

Opis:

Small pelagic fish such as sardine show strong recruitment variability often associated with environmental changes influencing the spawning process and ultimately, affecting population dynamics. Sardine (Sardina pilchardus, Walbaum 1792) is one of the most exploited pelagic species along the northwest African coast. The main spawning occurs during the cold season (autumn—winter). A time-series autumn—winter surveys extending from 1994 to 2015 sampled sardine eggs, along the southern area of the Moroccan Atlantic coast (26°N—21°N) were analyzed. The present work focuses on examining the inter-annual variability of the spawning habitat by analyzing the spatial-temporal variability of sardine egg distribution and density extracted from the data collected over the period 1994—2015. Generalized additive models (GAM) were used to detect the relationships between the sardine distribution, expressed as egg density and the presence or absence data and relevant hydrobiological environmental variables, such as salinity, temperature and zooplankton biomass. The generalized additive models showed significant relationships between the environment variables (SST, SSS and Zooplankton biomass) and sardine density, but not with sardine presence. Given that the study area is characterized by high mesoscale features and significant upwelling activities, the variability of upwelling processes could explain the changes of spawning ground position and thermal window

Opis:

Comparability of data collected within collaborative programmes became the key challenge of analytical chemistry in the 1990s, including monitoring of the marine environment. To obtain relevant and reliable data, the analytical process has to proceed under a well-established Quality Assurance (QA) system with external analytical proficiency tests as an inherent component. A programme called Quality Assurance in Marine Monitoring in Europe (QUASIMEME) was established in 1993 and evolved over the years as the major provider of QA proficiency tests for nutrients, trace metals and chlorinated organic compounds in marine environment studies. The article presents an evaluation of results obtained in QUASIMEME Laboratory Performance Studies by the monitoring laboratory of the Institute of Meteorology and Water Management (Gdynia, Poland) in exercises on nutrient determination in seawater. The measurement uncertainty estimated from routine internal quality control measurements and from results of analytical performance exercises is also presented in the paper.

Opis:

The brackish water environment of the Baltic Sea is dominated by a strong gradient of salinity and along with salinity the benthic diversity decreases – salinity is regarded as the master factor regulating benthic diversity in brackish habitats. In this scheme, consistently small patches of comparatively higher or lower benthic diversity do emerge in areas where either environmental or anthropogenic impacts on the benthic habitat change drastically over short spatial distances. Hence, spatial diversity of ecological factors creates diversity among benthic colonization and community structures. We show through a logistic modeling approach the possibility to predict thereby induced benthic colonization areas and community structures inside the broad scheme of a brackish water habitat. This study bases upon quantitative macrozoobenthic abundance data collected over a period of 4 years. It clearly demonstrates the need to analyze species’ relationships in gradient systems such as the Baltic Sea and provides a tool to predict natural and anthropogenic forced changes in species distribution.

Opis:

In the process of oil exploitation and transportation, large amounts of crude oil are often spilled, resulting in serious pollution of the marine environment. Forecasting oil spill reverse trajectories to determine the exact oil spill sources is crucial for taking proactive and effective emergency measures. In this study, the backward-in-time model (BTM) is proposed for identifying sources of oil spills in the East China Sea. The wind, current and random walk are three major factors in the simulation of oil spill sources. The wind drag coefficient varies along with the uncertainty of the wind field, and the random walk is sensitive to various traits of different regions, these factors are taken as constants in most of the state-of-the-art studies. In this paper, a self-adaptive modification mechanism for drift factors is proposed, which depends on a data set derived from the drifter buoys deployed over the East China Sea shelf. It can be well adapted to the regional characteristics of different sea areas. The correlation factor between predicted positions and actual locations of the drifters is used to estimate optimal coefficients of the BTM. A comparison between the BTM and the traditional method is also made in this study. The results presented in this paper indicate that our method can be used to predict the actual specific spillage locations.

Most of the coefficients used in the model are taken from the literature,co ntaining values from various published studies and parameters derived for similar species. The parameters for growth are presented in Part 1; those for population dynamics are given in Part 2. Ingestion rates,whic h are dependent on developmental stage, food supply,temp erature and weight of the animals, are estimated for Acartia bifilosa at 15◦C from the Gdańsk Deep after the experimental data of Ciszewski & Witek (1977). In Part 1 the model presents the change in mean individual mass in successive stages. Quantitative formulae are obtained describing the effects of temperature and food concentration on the development time of Acartia spp. for each of the model stage groups. The generation time during the seasons in the upper layer of the Gdańsk Deep is also determined. The simulations computed here are similar to the experimental results. Part 2 (Dzierzbicka-Głowacka et al. 2009 – this issue) will evaluate egg production as a function of the above-mentioned parameters,temp erature and food availability.

Opis:

This study presents how human-altered hydrographical settings (flow restrictions) impacts the natural distribution and community structure of copepods in the Kochi Backwaters (KBW), the largest monsoonal estuary along the southwest coast of India. This study is primarily based on an extensive seasonal sampling in the KBW and their comparison with a historical data set. Thannermukkom Barrage (TB) was built in the southern section of the KBW in the 1970s to prevent saline water intrusion to the upstream during the non-monsoon periods. Thirteen locations (1—4 in the downstream, 5—9 in the midstream, and 10—13 in the upstream) were sampled in this study over the entire stretch of the KBW during the Pre-Southwest Monsoon (PRM), Southwest Monsoon (SWM), and Post-Southwest Monsoon (PSWM). The overall effect of TB in the KBW is a seaward push of mesohaline conditions during all seasons with varying intensities. In response to the seaward push of mesohaline conditions, copepods Acartiella keralensis, Acartia plumosa, Acartia sp., Pseudodiaptomus annandalei, Pseudodiaptomus serricaudatus, Euterpina acutifrons and Oithona brevicornis showed a corresponding spatial shift for their highest abundance and diversity from midstream during PRM to the downstream during the SWM/PSWM. Multivariate and IndVal analysis demarcated many indicator species of copepods of different hydrographical settings in the KBW. A comparison with the historical data set showed that there is an apparent long-term change in hydrography, copepod composition and community structure in the upstream of the KBW due to TB.

Opis:

Short sediment cores from the eastern Gotland Basin were investigated using a multi-proxy approach in order to reconstruct the environmental conditions of the area during the past 1000 years. Sediment data and facies were discussed in relation to hydrographic features (salinity, oxygen) and climate change. During the medieval warm period (MWP), from about 900 to 1250 AD, the hydrographic and environmental conditions were similar to those of the present time (modern warm period, since about 1850): a temporally stable halocline, caused by regular saline water inflows from the North Sea, prevents vertical mixing and leads to bottom water anoxia and the deposition of laminated, organic-rich sapropels. During the period from about 1250 to 1850, referred to as the cold phase (including the Little Ice Age), the environmental conditions of the central Baltic Sea were distinctly different: the lower salinity, resulting from reduced North Sea water inflows, allowed vertical convection of the water column and long-term stable ventilation of the sea bed (oxic stage). Both the productivity of the planktonic ecosystem as well as the preservation of organic matter in the sediments improved during the warm periods. The anthropogenic impact can be identified within the recent laminated sequence by a temporal reconstruction of pollutant deposition. Our findings imply a climate-change driven shift in the environmental conditions and the ecosystem of the Baltic from the north to the south and back to the north.

Opis:

Phytoplankton community, diatom to dinoflagellate ratio and pigment composition in surface waters with nutrient data from April 2013 to March 2014 were monitored in the south-eastern (SE) Black Sea using high performance liquid chromatography (HPLC) and microscopic analyses. Microscopic examination revealed a total of 71 species that consist of dinoflagellate (58%), diatoms (25%) and other groups (17%). Microscopy and HPLC-based pigment analyses revealed almost similar results which suggest that the phytoplankton community is mainly composed of diatoms, dinoflagellates and coccolithophores. Fucoxanthin (mean 0.35 ± 019 μg L−1), peridinin (mean 0.18 ± 0.14 μg L−1) and 19-hexanoyloxyfucoxanthin (mean 0.24 ± 0.15 μg L−1) are prominent pigments which showed significant correlation with Diatom-C (r2 = 0.63–0.71, p < 0.05), Dinoflagellate-C (r2 = 0.49–0.80, p < 0.05) and Coccolithophore-C (r2 = 0.72–0.82, p < 0.05), respectively. Mean carbon biomass of diatoms (36.50 ± 9.72 μg L−1) was higher than that of dinoflagellates (33.32 ± 9.05 μg L−1). Significant differences were also observed in nutrient ratio (N:P and Si:N) (One-way ANOVA, p < 0.05). Results illustrate that HPLC-based pigment approach can be used for taxonomic characterisation of phytoplankton groups in the SE Black Sea. Moreover, relatively high dinoflagellate species dominancy and significant correlations between Phyto-C and marker pigments indicate that phytoplankton community composition is shifting towards much smaller groups in SE coasts of the Black Sea.

Opis:

It is studied the distribution of Hg in bottom sediments of estuaries on the banks of the open water area of the Vistula Lagoon and in the Kaliningrad Sea Canal (KSC) isolated from it. Methods for the determination of Hg: inversive voltammetry and highly sensitive flameless atomic absorption spectrometry. It has been established: from spring to autumn the activation of storms and surge events in the lagoon, intensification of the water flushing regime of the channels ensure a significant Hg decrease in river mouths, but in dynamically weakened KSC conditions - an increase in Hg (from 0.05 to 0.85 mg / kg). In KSC bays, the safe level of Hg (0.3 mg / kg) for the period 2000-2015 was not exceeded (0.008 to 0.216 mg / kg), which indicates a favorable ecological and epidemiological situation. Hg determinations by low-sensitivity methods can be used only in qualitative assessments of the variability in concentrations of any dangerous toxicant. Finding a reliable amount of Hg in river mouths requires the use of highly sensitive methods of analysis.

Opis:

The study covered the aquatic environment of two small rivers in Western Pomerania, Poland, such as the Czerwona and the Grabowa. Its purpose was to determine aluminium bioaccumulation in the aquatic environment by testing water, bottom sediments and aquatic plants. Samples were taken in the summers of 2008-2011. pH, electrolytic conductivity and aluminium concentration were determined in water samples, while the sediment and plant samples were submitted to analyses of the aluminium content. The water pH oscillated between 6.04 and 8.95, while the electrolytic conductivity ranged from 440 to 1598 μS cm-1. The aluminium concentration in the river water was up to 0.138 mg Al dm-3 in the Czerwona and up to 0.425 mg Al dm-3 in the Grabowa. The maximum aluminium content in the bottom sediments was 47.01 mg Al kg-1 in the Czerwona River and 26.15 mg Al kg-1 in the Grabowa River. The maximum aluminium content in the aquatic plants sampled from the Czerwona was 91.63 mg Al kg-1, and from the Grabowa – 1,077 mg Al kg-1. The bioconcentration factor (BCF) of aluminium for the Czerwona River ranged from 5.06 to 24,052, and for the Grabowa River – from 1.10 to 70,132. The concentration factor (CF) of aluminium in the bottom sediments oscillated between 66.72 and 23,492 in the Czerwona River and between 14.81 and 2,763 in the Grabowa. The aluminium content in the two rivers was relatively low in the water, sediments and aquatic plants, which is typical of environments without strong anthropopressure. The values fell within the limits set by environmental water quality standards. The low aluminium accumulation degrees in the biotic and abiotic components indicate that the environments of the two rivers have a low load of aluminium compounds.

Opis:

The aim of the TOPVOYS project supported by the MarTERA ERA-Net Cofund program within the European Commission is to advance and implement analyses tools and decision support system for voyage optimisation. Based on marine weather analyses and forecasts combined with near real time satellite-based observations of wind, wave and surface current conditions as well as sea surface temperature fields the best shipping route are examined. The proposed approach aims to identify the optimum balance between minimisation of transit time and fuel consumption as well as reduction of emissions without placing the vessel at risk to damage and or crew injury. As such it is compliant with the International Maritime Organization guidelines [6] for ship routeing to keep the traffic smooth and avoid accidents, notably in the presence of unfavorable marine meteorological conditions. The tool performances will be demonstrated both in post-voyage analyses and real time operations for the North Atlantic Ocean crossings, voyages from Europe through the Mediterranean Sea and the Suez Channel to the Far East (e.g. China, South Korea) and voyages around Southern Africa.

New particle formation and growth were observed at a coastal site (Preila station, Lithuania) during 1997 and 2000–2002. The total amount of data analysed covers 291 one-day periods, 45 (15%) of which were long-term, new particle formation days. Short-term nucleation events (from a few minutes to one hour) and long-term events (from one to eight hours) were identified. The mean particle growth rate, condensation sink and condensable vapour source rate during nucleation events were 3.9 nm h−1, 1.45 × 10−3 cm−3 s−1 and 7.5 × 104 cm−3 s−1 respectively. The average formation rate J10 was 0.4 cm−3 s−1. The nucleation events were accompanied mainly by air masses transported from the north (43%) and north-west (19%). Meteorological parameters and trace gas (O3, SO2, NO2) concentrations were also analysed. It was found that nucleation events are related to high levels of solar radiation.

Opis:

Exhaust gas emissions from ships are increasingly polluting the air environment seriously. Therefore, the MARPOL 73/78 Annex VI is applied for all ships from 2017, Annex VI provided that the concentrations of NOx,SOx CO contained in ship’s exhaust gases must be less than 6.4 g/kWh, 0.6 g/kWh, and 5.5g/kWh respectively. Today, there are many solutions to reduce pollution emissions from exhaust gas of ships, such as improving combustion, using oil emulsion, using biofuel,…However, these solutions also have a handful of disadventages such as being unable to thoroughly resoulve problems, high cost, and very difficult to improve the quality of ship exhaust gas emissions for old ships. Exhaust gas treatment method uses a centralized treatment system where exhaust gas from the thermal engines is taken in a centralized treatment system before discharging into the air. After centralized treatment system, in comparision with raw exhaust gas, soot can be reduced by 98%, NOx can be reduced by 75%, SOx can be reduced by 80%. This method of treatment is not only low cost, good quality but also make marine heat-engines still use traditional fuels as well as need not improve its structure.

Opis:

Since 1981, acoustic information collected in the form of calibrated measurements of integrated echo energy has been applied at the Sea Fisheries Institute to observe the relationships between fish distribution and environmental factors. Data gathered in different seasons for each elementary distance unit (EDSU) at standardised depth intervals were compared to the values of selected environmental parameters measured in parallel. Acoustic, biological and hydrological data were correlated in space and transferred to the complex database, enabling 4D analysis of numerous factors characterising a wide range of fish behaviour. A number of methods and standards of comparisons are described to explain how to improve understanding of the relationship between 3D spatial environmental gradients and fish distributions. The results of various case studies, including the influence of hydrologic and seabed characterising factors, illustrate the practical application and validity of the methods. Particular attention is given to indicators of the dependence of local fish biomass density on the temperature structure in the sea.

Opis:

A population of Cerastoderma glaucum Poiret 1789 was studied in the Polish coastal zone (up to 3 Nautical miles) of the Baltic Sea within the Puck Bay and part of the Gulf of Gdańsk. The frequency (F) in the sheltered coastal zone of bays was high (65%), whereas at the exposed open coast of the Middle Pomerania it was lower (43%). Also, abundance in the Puck Bay and the Gulf of Gdańsk was over 3-fold higher than in the coastal zone of the Middle Pomerania. By means of classic statistical methods (essential tests) we proved the significance of differences between mean abundance at west and east transects in estuaries and between open coast and estuaries. The multivariate regression and classification trees (MR&CT) indicated that biomass and abundance of C. glaucum in the Baltic Sea were affected by the kind of bottom, whereas depth and distance to the bank influenced cockles' abundance and biomass in bays. The population's structure in the Puck Bay and the Gulf of Gdańsk was determined mainly by the depth. In the Wieprza River estuary only specimens from age group 1+ were found. On all the other studied profiles cockles lived up to 3 or 4 years and the dominant group was 2+. The highest mean width of shell was in the Słupia River estuary, and in the bays shell width increased from west to east. In comparison to the other bivalves inhabiting the discussed area, C. glaucum does not play an important role as food source for fish and other consumers but may serve as an indicator of environmental conditions.
Badano populację małża sercówki bałtyckiej Cerastoderma glaucum (Poiret, 1789) w polskiej strefie przybrzeżnej Bałtyku (do 3 Mm), oraz w Zatoce Puckiej i Zatoczce Gdyńskiej (część Zatoki Gdańskiej). Frekwencja dla strefy przybrzeżnej zatok była wysoka i wynosiła średnio F = 65%, a dla strefy przybrzeżnej Wybrzeża Środkowego tylko F = 43%. W strefie przybrzeżnej Zatoki Puckiej i Gdyńskiej zagęszczenie Cerastoderma było ponad 3-krotnie wyższe w porównaniu do masy mokrej w strefie przybrzeżnej Wybrzeża Środkowego. Przy użyciu klasycznych metod statystycznych (testów istotności) wykazano różnice w średnim zagęszczeniu pomiędzy profilami wschodnimi i zachodnimi w estuariach oraz pomiędzy otwartym wybrzeżem a strefami estuariowymi. Zastosowana metoda MR&CT (drzewa regresyjne) dla danych z Morza Bałtyckiego wskazała, że na biomasę i zagęszczenie Cerastoderma wpływ ma jedynie granulacja podłoża, natomiast na obszarze zatok na zagęszczenie wpływa głębokość, a na biomasę odległość od brzegu. Struktura populacji Cerastoderma glaucum zasiedlającej Zatokę Pucka i Gdańską jest determinowana głównie przez głębokość. Najkrócej sercówki żyły w estuarium Wieprzy, gdzie występowały wyłącznie osobniki z grupy wiekowej 1+. Na pozostałych badanych pod tym względem profilach małże te dożywały wieku 3 i 4 lat, z dominującymi starszymi grupami wiekowymi, głównie 2+. Badania szerokości muszli wykazały, że średnia szerokość muszli badanych Cerastoderma na obszarze Wybrzeża Środkowego była największa w estuarium Słupi, natomiast na obszarze zatok zasadniczo wzrastała z zachodu na wschód. W porównaniu do innych gatunków małży zasiedlających badany obszar, Cerastoderma glaucum, ze względu na niewielką liczebność, nie odgrywa większej roli ekologicznej oraz nie tworzy bogatej bazy pokarmowej dla ryb i innych hydrobiontów, może natomiast posłużyć jako organizm wskaźnikowy niekorzystnych zmian zachodzących w środowisku.

Morze Bałtyckie powinno stać się obszarem szczególnego zainteresowania Sojuszu Północnoatlantyckiego, jako głównej organizacji bezpieczeństwa regionu, tu bowiem leży wschodnia granica NATO. Nie oznacza to powrotu do strategii i rozwiązań organizacyjnych sprzed transformacji Organizacji Traktatu Północnoatlantyckiego. Oznacza konieczność dostosowania struktur do nowych wyzwań, szczególnie w morskiej domenie działań.
Recent security changes in the Baltic Sea region indicate that this area has to be considered as the area of potential risk caused by the actions of the Russian Federation, NATOand each country of the region. Those changes in security environment force the adaptation of international security structures and generate a change in their approach to achieve its new tasks and goals. The Baltic Sea must become an area of particular interest to Alliance - as themain security organization in the region - because here is the critical eastern NATO border. This does not mean a return to the previous strategy and organizational structures. This means the necessity to adapt structures to new challenges, particularly in the maritime domain.

Opis:

The motion of water due to surface waves is the most dynamic factor observed in the marine environment. In this review various aspects of the wave modelling of non-linear, steep surface waves and their role in the atmosphere-ocean interaction are discussed. Significant improvements in wave forecasting have been made in the last ten years. This is to a large extent related to substantial progress in the description of wind forcing and other processes, as well as to the more efficient use of satellite observations and assimilation methods. One striking observation is the increasing variety and complexity of models in which more physical processes are implemented, greater precision and resolution achieved and extended ranges of applicability demonstrated. However, in order to evaluate the applicability of particular models, comparison with high quality experimental data, collected in nature or under laboratory conditions, is necessary.

Opis:

The paper presents some results of research on the fluorescence properties of petroleum oil-in-water emulsions. The research addresses the question of measuring and modelling light fields in an oil-polluted marine environment. The fluorescence of the emulsion manifests itself in the spectral range from 260 to over 400 nm and is much less intensive in the visible light region. Fluorescence is always weaker than the radiation scattered in an emulsion. The measurement and modelling of ultraviolet radiation scattering requires fluorescence to be taken into consideration, but in the visible spectral region this phenomenon is negligible.

Opis:

Marine abandonment immersion suits are a vital piece of safety equipment intended to protect individuals from exposure to harsh environmental elements. The operational effectiveness of a well maintained and fitted suit depends on the ability of a user to correctly don a suit system. Thirty-two participants performed immersion suit donning trials in six experimental conditions. Dynamic, pre-abandonment marine emergency scenarios were simulated using a six degrees of freedom motion platform and varying environmental lighting levels. This article details user-suit interaction challenges encountered throughout immersion suit donning tasks and examines their connection to safety and survival in marine emergencies. Analysis of user-suit functionality during the donning process is critical for identifying current deficiencies in order to develop future design solutions, training methodologies and ultimately improve users’ practical competencies.

Opis:

Spring development in the hydrolittoral zone was investigated at five wave-sheltered and five wave-exposed sites on four occasions from late March to late May (every third week). The number of species was higher at the sheltered locations and increased significantly over time. The difference in community structure was significant: over 95% of the Bray-Curtis dissimilarities were due to the biomass of only eleven taxa, and the total Bray-Curtis dissimilarity between exposed and sheltered sites was 75%. Macroalgae made up 70–80% of the total biomass and was dominated by filamentous species. In contrast to previous studies, macroalgal biomass was higher at the exposed sites, which may be due to the fact that this was a spring study, unlike previous studies, which were conducted during summer.

Opis:

Tourism has become one of the most important examples of human activities and this is the fact nobody can question. Contemporary people tend to have more and more free time, their economic status is relatively high, they have easy access to numerous unknown before areas and their thirst for experiencing something new and satisfying natural curiosity make them become interested in the surrounding world. The purpose of the present article is on the one hand describing the factors that influence considerably the development of tourism in the Baltic regions illustrated by an example of the gmina of Ustronie Morskie, and on the other hand presenting the tendencies of tourism trends and their evolution in the period of the recent 20 years. The article focuses on the period of social and economic transformations. Attractive location, picturesque views and interesting flora make the described area a perfect place to develop the whole infrastructure necessary to interest a great number of tourists. The present paper describes a group of villages located in the vicinity of the Baltic Sea: Ustronie Morskie, Sianożety, Winiotowo and Olszyna. The biggest administrative unit is Ustronie Morskie (2 030 inhabitants). After having completed the research, the results show that the best developed part of the described region is located between the Baltic shore and a railway line connecting Kołobrzeg and Koszalin.
Turystyka stała się jednym z ważniejszych przejawów aktywności życiowej współczesnego człowieka. Celem prezentowanego artykułu jest z jednej strony dokonanie ogólnej oceny czynników, które w istotny sposób wpłynęły na rozwój turystyki w strefie nadbałtyckiej na przykładzie gminy Ustronie Morskie, z drugiej zaś strony przedstawienie zmian w ruchu turystycznym, jakie dokonały się w ostatnich 20 latach, ze szczególnym uwzględnieniem okresu transformacji społeczno-gospodarczej. W omawianej gminie istotną rolę w rozwoju osadnictwa turystycznego odgrywa atrakcyjność przyrodniczo-krajobrazowa z elementami rzeźby terenu, wód powierzchniowych, szaty roślinnej, a przede wszystkim położenie nadmorskie. Na tle ogólnej charakterystyki sieci osadniczej zwrócono szczególną uwagę na zespół wsi Ustronie Morskie–Sianożęty oraz ściśle z nimi związaną wieś Wieniotowo i osadę Olszyna. Miejscowości te mają położenie typu nadmorskiego. Największa jednostką w pasie nadmorskim jest Ustronie Morskie (2 030 mieszkańców), które pełni zróżnicowane funkcje turystyczno-usługowe, obsługi administracyjnej gminy oraz rolnictwa. Generalnie można przyjąć, że zabudowa mieszkaniowa skupia się w wąskim pasie między wybrzeżem Bałtyku a linią kolejową Kołobrzeg–Koszalin. Z badań jakie przeprowadzono wynika, że ruch turystyczny jest bardzo mocno uwarunkowany bazą noclegową. Podkreślić należy, że przejęty po II wojnie światowej przez Fundusz Wczasów Pracowniczych majątek służący obsłudze ruchu turystyczno-wczasowego był intensywnie rozwijany, szczególnie w latach siedemdziesiątych za sprawą wielkich inwestycji zakładów przemysłowych z całego kraju. Przekroczenie liczby 10 000 miejsc noclegowych nastąpiło już w 1975 r. Z uzyskanych materiałów wynika, że w ostatnim 25-leciu miały miejsce dwa absolutne rekordy notowanego ruchu turystycznego – pierwszy w 1980 r. i drugi w 1985 r. Nigdy więcej oficjalnie nie udało się osiągnąć takiego stopnia wykorzystania istniejącej infrastruktury turystycznej. Państwowa i spółdzielcza kolonizacja turystyczna osiągnęła swój szczyt opierając się na działalności aż 123 ośrodków wczasowych i kolonijnych. Dysponowały one prawie 12 000 miejsc noclegowych. Przemiany społeczno-gospodarcze zapoczątkowane w Polsce w 1989 r. wyraźnie wpłynęły na funkcjonowanie państwowych i spółdzielczych podmiotów gospodarczych. Bezpośrednie badania terenowe pozwoliły ustalić, że w roku 2001 w badanych 146 obiektach, które można było określić jako: ośrodki wczasowe, rekreacyjne, letniskowe, campingowe i leczniczo- sanatoryjne znajdowało się około 13 500 miejsc noclegowych. W kwaterach prywatnych następuje również wyraźna modernizacja obiektów turystycznych. Ze wzrastającym ruchem turystycznym stale zwiększa się sieć urządzeń towarzyszących.

It is essential to evaluate safety of marine traffic for the improvement of efficiency and safety of marine traffic. Spread of AIS makes observation of actual marine traffic more easily and faster than before. Besides, description of collision avoidance behaviours of ships are indispensable to simulate a realistic marine traffic. It is important to develop and implement an algorithm of collision avoidance corresponding to a target traffic or target area into the marine traffic simulation because actual actions for collision avoidance depend on circumstances where ships are sailing. The authors developed an automated marine traffic simulation system with AIS data. And in this paper, we proposed a series of systematic procedures for marine traffic simulation including analysing for collision avoidance behaviours using AIS data.

Opis:

When it comes to gas turbines, their main problem concerning pollutant emissions is represented by nitric oxides. Among other emissions, sulphur oxides being much reduced due to the use of liquid distilled and gas fuels with a low content of sulphur. Using water or steam injection became the favourite method during the '80s and especially the '90s since "dry" methods and catalytic reduction were both at the beginning of the development phase. Catalytic convertors have been used since the '80s and they are still used although the costs of renewing the catalyst are very high. In the last twenty years a gradual decrease has been registered on the limits of nitric oxides from 75 ppm to 25 ppm, and now the target is oriented towards the 9 ppm level. The evolution of burning technologies of combustion makes it possible to control the level of production of nitric oxides even from the source without being necessary to use "humid" methods. This, of course, opened the market for gas turbines because they can function even in areas with limited quality water reserves, such as maritime platforms and in the desert. In this paper, we are going to show that, although water injection is still used, "dry" control technologies of burning became favourite methods for the majority of users on the industrial power generators market. The great dependency between the creation of nitric oxides and the temperature reveals the effect of direct water or steam injection on reducing nitric oxides. Recent research showed that a reduction up to 85% of nitric oxides may be obtained by using the water or steam injection all together with the improvement of aerodynamic character of the burning room.

Opis:

The majority of the southern Baltic Sea seabed encompasses homogenous softbottom sediments of limited productivity and low biological diversity, but shallow productive areas in the coastal zone such as wetlands, vegetated lagoons and sheltered bays show a high variety of benthic habitat types offering favourable biotopic conditions for benthic fauna. Within Polish marine areas, semi-enclosed Puck Bay (the western part of the Gulf of Gdansk) ´ features an exceptionally diverse environment covering a range of benthic habitats which underscores its unique biological value and aesthetic quality and providing an impetus for conservation and ecosystem-based development. Full-coverages maps on benthic habitats in this area are therefore a necessary foundation for maritime spatial planning and implementation of strategies for sustainable management and protection of the coastal environment. This study presents the first comprehensive description and distribution of benthic habitats in Puck Bay which were categorised using the revised EUNIS 2019 classification system. Typological analyses were carried out based on inventory datasets from 1995 to 2019 including scientific publications, satellite images, open databases, topographic and geological maps, reports, theses, information available on websites and unpublished data shared willingly by individual researchers and administrative institutions. Collating various spatial data sources, that were first georeferenced and then visualized using techniques available in ArcMap 10.4.1 software (Esri), resulted in the mapping of benthic habitats and sites of important and protected plant species, which can contribute to the high confidence in environmental assessments and monitoring activities.

Opis:

This paper summarises current knowledge of goods and services in the Polish Exclusive Economic Zone of the Baltic Sea ecosystem. It reviews specific properties of the Baltic that could be used for economic valuation. Goods and services range from the familiar resources of fish and minerals, which were valued with the Productivity Method, to less obvious services provided by the ecosystem such as biofiltration in coastal sands, valued with either the Replacement Cost or Damage Cost Avoided methods. Disservices to the marine ecosystem are also considered, e.g. erosion and coastal flooding, including the costs of planned mitigating measures. This paper emphasises the importance of using valuation methods to help make better-educated decisions for the sustainability of the Baltic Sea.

Opis:

Organic matter is a minor yet important component of the marine environment. The aim of this study was to investigate the diurnal and seasonal changes in dissolved and particulate organic carbon (DOC and POC, respectively). Thus, DOC and POC as well as chlorophyll a (Chl a), δ13C, NO3−, NO2−, NH4+, PO43−, salinity, pH, and temperature were regularly measured in samples collected for 24 h (2-h resolution) in the Gdańsk Deep (54°44.730′N, 19°08.531′E) at three water depths (1, 10, and 40 m) during sampling campaigns in 2011 (May), 2014 (May), and 2015 (January, March, May, July, September, November). Seasonal variations in DOC and POC followed the seasonality of Chl a (proportional trend) and nutrients (reverse trend) concentrations. Diurnal oscillations were detected in six out of the eight measurement series. The strongest diurnal variability in both POC and DOC occurred in May 2011 and March 2015, when phytoplankton activity was highest (high Chl a). The surprisingly low δ13C values (range: −28‰ to −24‰) measured over the course of the study revealed the gaps in our knowledge of the isotopic characteristics of terrestrial- vs. marine-derived particulate organic matter.

Opis:

This paper presents a comparative analysis of manoeuvring patterns through the fairway which is marked with physical and virtual Aids to Navigation (AtoN). The impact of V-AtoN environment on decision-making and on consequent manoeuvres has never been studied in such a way. The results published in this paper were obtained using TRANSAS Navi Trainer 5000 and TRANSAS ECDIS 4000 simulators where 12 deck officers with at least 5 years of sea service participated. The results of the study indicate that there is a significant difference in manoeuvring patterns between the two environments. In case of virtual environment, more intense drift angles, ROTs as well as XTDs are observed. The paper demonstrates significant impact of virtual environment on behaviour of OOW.

Opis:

The bioaccumulation ability of radionuclides 51Cr, 54Mn, 57Co, 60Co, 65Zn, 85Sr, 109Cd, 110mAg, 113Sn, 137Cs and 241Am in two red algae species from the southern Baltic Sea – Polysiphonia fucoides and Furcellaria lumbricalis – was determined under laboratory conditions. P. fucoides demonstrated better bioaccumulative properties towards most of the investigated radionuclides. As a result, P. fucoides can be recommended as a good bioindicator of radioactive environmental pollution. The bioaccumulation of radionuclides in F. lumbricalis was studied during an extended laboratory experiment. The initial extensive uptake of radioisotopes was followed by the rapid removal of cations; in general, concentrations tended to decrease with time. 137Cs displayed a different behaviour, its concentration in the algae increasing over time mainly due to its large ion radius; this is a factor that could be responsible for the stronger mechanical and chemical bonding of Cs+ and that could hamper the movement of ions in both directions.

Opis:

A substantial part of the energy of wake waves from high-speed ships sailing in shallow water is concentrated in nonlinear components which at times have a solitonic nature. Recent results of investigations into solitonic wave interactions within the framework of the Kadomtsev-Petviashvili equation and their implications for rogue wave theory are reviewed. A surface elevation four times as high as the counterparts occurs if the properties of the interacting waves are specifically balanced. The slope of the water surface may increase eightfold. The resulting structure may persist for a long time. Nonlinear wake components may exert a considerable influence on the marine ecosystem in coastal areas.

Opis:

The total concentrations of BDEs in Baltic herring, caught in different years (2002–08) from various areas of the Baltic, and in Atlantic herring (2006) can be reasonably well described by a single concentration vs weight relationship. Samples collected a few years earlier and analysed by others show a slightly different relationship. This indicates that the weight of the fish is an important factor determining the level of contamination and that the contamination apparently did not increase between 1999 and 2008. However, two Baltic herring samples collected in 2007 contained, for reasons unknown, very high concentrations of BDE 209. The BDE profiles (concentrations scaled to a sum of 100) varied a great deal. It is impossible to determine how much of this variation is real and how much is caused by errors in the analyses. The concentration of the BDE 75 was much higher in the Atlantic than in the Baltic herring. Even after taking this into consideration, however, the BDE profile in Atlantic herring is different from the BDE profiles in Baltic herring.

Opis:

The influx of solar radiation to the Baltic Sea and its penetration into its waters is described on the basis of selected results of optical and bio-optical studies in the Baltic published by various authors during the past ca 50 years. The variability in the natural irradiance of this sea is illustrated on time scales from short-term fluctuations occurring during a single day to differences in mean monthly values over a period of many years. Data on variability of the proportions between UV, VIS and IR energy in the light reaching the sea surface are also discussed. Long-term monthly mean values of the incident solar radiation flux at the surface of the Baltic Proper are given; they were obtained from meteorological and solar radiation measurements and model approximations. The transmittances of these mean monthly radiation fluxes across the surface of the Baltic are given, as are the typical energy and spectral characteristics of the underwater irradiance, its attenuation with depth in the sea and the associated euphotic zone depths, as well as typical ranges of variability of these characteristics in different Baltic basins. Some of these characteristics are illustrated by typical empirical data. These mean values are not fully representative, however, because with the sole use of classical in situ measurement methods from on board research vessels in the Baltic, it has not been possible to gather a sufficiently representative set of empirical data that would adequately reflect the variability of the optical haracteristics of all the basins of this sea. The article goes on to introduce the statistical model of vertical distributions of chlorophyll a concentration in the Baltic and the bio-otical model of Baltic Case 2 waters, the use of which contribute very significantly to this description of the optical characteristics and will enable this data set to be hugely expanded to include all the Baltic basins. This opportunity is presented by the optical parameterization of Baltic Case 2 waters, i.e. by the mathematical formulas of the model linking the coefficient of attenuation of downward irradiance with the surface chlorophyll a concentration, as well as the method developed for the efficient and systematic satellite remote sensing of the chlorophyll a concentration over the entire Baltic Sea area.

Opis:

The paper discusses the possibilities of modelling the bi-directional reflectance distribution function (BRDF) in sea areas polluted by oil. Three sea basin models are considered: a coastal one free of oil, one polluted by an oil film and one polluted by an oil emulsion. The following concentrations of oil were compared: for the film, 1 cm3 of oil per 1 m2 water surface, for the emulsion 1 cm3 of oil in 1 m3 of water. The optical properties of Romashkino crude oil were taken into consideration, as were various angles of incident solar light. The conversion of BRDFs into a directional distribution of the optical contrast of polluted areas is demonstrated.

Opis:

The three-spined stickleback Gasterosteus aculeatus (L.) has been a very frequent fish in the Baltic coastal waters. In the Baltic Sea occurred three morphological forms of the three-spined stickleback: trachurus, semiarmatus and leiurus. The distribution and frequency of all forms of the stickleback in the Baltic have been different. The examined sticklebacks were collected from the Gulf of Gdańsk (Gdynia, Puck, Hel) and the mouth of the Dead Vistula (Górki Wschodnie). The studies on the correlation between the morphological forms of the stickleback and parasites’ infestation were carried out. Some species of parasites infected first of all form trachurus or leiurus of the stickleback. Correlation was observed in some of marine parasites like Thersitina gasterostei (Pagenstecher, 1861) (Copepoda) and Gyrodactylus arcuatus (Bychowsky, 1933) (Monogenea), infected generally trachurus form. Freshwater ciliates from the family Trichodina or plerocercoids of Schistocephalus solidus (Müller, 1776) (Cestoda) were found generally on/in form leiurus.
Ciernik jest rybą wykazującą niezwykłą zmienność morfologiczną. W związku z liczbą tarczek kostnych pokrywających ciało ryby, wyróżnia się kilka typów morfologicznych. Przypisuje im się też różne preferencje co do środowiska. Formę trachurus uważa się za morską, odbywajacą tarło w słonawych wodach Bałtyku, semiarmatus za pośrednią, z preferencją do wód słodkich a leiurus traktuje się jako odmianę słodkowodną, rozradzajacą sie w pobliskich rzekach i kanałach melioracyjnych. W Bałtyku wystepują wszystkie wspomniane formy morfologiczne ciernika, których rozmieszczenie i liczebność wzdłuż naszego wybrzeża jest różna. Trzy formy były stwierdzone w Zatoce Gdańskiej, przy czym najliczniej stwierdzano formę trachurus a najrzadziej leiurus. Na zachód od Zatoki Gdańskiej nie stwierdzono formy leiurus. Wyniki przeprowadzonych badań parazytologicznych ciernika, wykazały związek pomiędzy polimorfizmem ciernika a stopniem inwazji niektórych pasożytów. Korelacje zaobserwowano między innymi w przypadku typowych dla ciernika widłonogów Thersitina gasterostei oraz przywr monogenetycznych Gyrodactylus arcuatus, które zarażały przede wszystkim cierniki trachurus. Wymienionym pasożytom, podobnie jak formie ciernika przypisuje się morski charakter. Inaczej przebiegała inwazja słodkowodnych orzęsków z rodzaju Trichodina oraz plerocerkoidów Schistocephalus solidus. Powyższe pasożyty zarażały najczęsciej słodkowodna forme leiurus.

Opis:

In the paper were presented the results of study for determination of natural (polonium 210Po, uranium 234U and 238U) and artificial (plutonium 238Pu, 239+240Pu and 241Pu) alpha radionuclides in aquatic environment of Poland and southern Baltic Sea as well as the recognition of their accumulation in marine trophic chain. The obtained results indicated that Vistula and Odra as well as Rega, Parsęta and Słupia are important sources of analyzed radionuclides in southern Baltic Sea. Total annual runoff of polonium, uranium and plutonium from Vistula, Odra and Pomeranian rivers to the Baltic Sea was calculated as about 95 GBq of 210Po, 750 GBq of 234+238U and 160 MBq of 238+239+240Pu. Investigation on the polonium 210Po, uranium 234U and 238U, as well as and plutonium 238Pu, 239+240Pu and 241Pu. concentration in Baltic biota revealed that these radionuclides, especially polonium and plutonium, are strongly accumulated by some species. The results indicate that the Baltic organisms accumulate polonium and plutonium from environment and the bioconcentration factors (BCF) range from 25 to 27 000. The Baltic Sea algae, benthic animals and fish concentrate uranium only to a small degree. In Baltic sediments, the concentration of uranium increases with core depth and it is connected with the diffusion of 234U, 235U and 238U from sediments via intersticial water to bottom water. The values of 234U/238U activity ratio in the sediments indicated that the possible reduction process of U(VI) to U(IV) and the removing of autogenic uranium from seawater to sediments in the Gdańsk Deep and Bornholm Deep constitutes a small part only.
W pracy przestawiono wyniki badań nad występowaniem naturalnych (polon 210Po, uran 234U i 238U) i sztucznych (pluton 238Pu, 239+240Pu i 241Pu) radionuklidów alfa promieniotwórczych w środowisku wodnym Polski i południowego Bałtyku, jak również rozpoznanie procesu ich nagromadzania w morskim łańcuchu troficznym. Wyniki badań wykazały, że Wisła i Odra oraz Rega, Słupia i Parsęta są ważnymi źródłami analizowanych radionuklidów w południowym Bałtyku. Całkowity roczny spływ polonu, uranu i plutonu wodami Wisły, Odry i rzek Przymorza został obliczony na 95 GBq dla 210Po, 750GBq dla 234+238U oraz 166 MBq dla 238+239+240Pu. Badania zawartości polonu 210Po, uranu 234U i 238U, jak również plutonu 238Pu, 239+240Pu oraz 241Pu w organizmach bałtyckich wykazały silne nagromadzanie w nich radionuklidów, szczególnie polonu i plutonu. Wartości współczynnika nagromadzania (BCF) polonu i plutonu w organizmach południowego Bałtyku mieszczą się w szerokim przedziale wartości od 25 do 27000. Bałtyckie wodorosty i organizmy zwierzęce nagromadzają uran w niewielkim stopniu. Z kolei w osadach bałtyckich stężenie uranu wzrasta z głębokością rdzeni, co związane jest z dyfuzją izotopów 234U, 235U i 238U za pomocą wody porowej do wody naddennej. Analiza wartości stosunku aktywności 234U/238U w osadach wykazała, że możliwa redukcja U(VI) do U(IV) i usuwanie autogenicznego uranu z wody morskiej do osadów w redukcyjnych rejonach Bałtyku: Głębi Gdańskiej i Głębi Bornholmskiej zachodzi w niewielkim stopniu.

Opis:

An important question stated in the presented paper is: Could rotifers be the indicators of climate change in the Antarctic environments? Rotifers are one of the most important components of the invertebrate fauna of the Antarctic freshwater and terrestrial ecosystems. However, investigations of their distribution, diversity and an ecological role in the environment have been widely neglected, mainly due to the methodological and taxonomical difficulties. During the investigations 176 species of rotifers were found, including the endemic and cosmopolitan species. Their existence is directly proportional to microvariations of humidity factor. Scientists still have poor knowledge about the occurrence of rotifer species in recently studied habitats e.g. cryoconite holes, nunataks or soil. Probably rotifers could be the indicators of climate change in the Antarctic freshwater and terrestrial ecosystems but more investigations and monitoring studies are needed.
