Opis:: The transport pipeline of lifting the underwater minerals to the surface of the water onto the ship during the movement of the vessel takes in the water a curved deformed shape. Analysis of the state of stability of the pipeline showed that if the flow velocity of fluid in the pipeline exceeds a certain critical value Vkr, then its small random deviations from the equilibrium position may develop into deviations of large amplitude. The cause of instability is the presence of the centrifugal force of the moving fluid mass, which occurs in places of curvature of the axis of the pipeline and seeks to increase this curvature when the ends of the pipeline are fixed. When the critical flow velocity is reached, the internal force factors become unable to compensate for the action of centrifugal force, as a result of that a loss of stability occurs. Equations describing this dynamic state of the pipeline are presented in the article.

Opis:: In this study, an analysis of deep sea shipping (DSS) container services, calling at Italian ports, is carried out. A comparison with analogous sets of data collected in the years 2011 and 2014 has been performed. The most important Italian port system is the Ligurian one, which includes the main Italian port, Genoa, which is the main access gate to the Padan Plain, the most productive area of Italy. However, other ports are also important: the Ligurian port of La Spezia and the hub port of Gioia Tauro. The comparison, with 2011 and 2014 data, has shown that while the number of DSS departures, from Italian ports, did not increase, the dimensions of the ships, which call at Italian ports, increased relevantly: this is in line with the current trend in container ship gigantism.

Opis:: The increasing use of automation in fishing vessels has improved trawling efficiency while directly affecting the fishing capacity and cost of fishing vessels. Among the various influencing factors, warp tension and warp length can be varied to automatically balance the retraction and release of warp control. We combined the two parameters and independently designed and developed the key equipment for fishing vessels—the warp dynamometer and meter counter—and control software. The accuracy of the warp tension and length measurements was improved. The designed equipment was applied to sea trials under different working conditions, and the test data records were exported. Next, filtered time-domain graphs of the required parameters were plotted through complex Fourier transform, first-order lowpass filtering, and inverse Fourier transform. The results of data processing using various parameters were compared and analysed to determine the variation trends of the parameters and verify the effects of their balance control. The results indicated that using an automatic balance control system that combines warp tension and warp length can be effective for the fishing operation of offshore double-deck trawlers. In addition, first-order low-pass filtering can be used to filter complex warp tension data. This study also determined the relationship between warp tension and experimental parameters such as warp length and ship speed during the release of control. After the balance control of warp tension and warp length, the net mouth area increased by 30.7% and 36.5%, respectively, and the fishing efficiency of the vessel improved considerably.

Opis:: Mimo wielkiego postępu w dziedzinie prac podwodnych problemy nurkowań głębokich nie są rozwiązane dostatecznie, gdyż są to nurkowania najtrudniejsze z punktu widzenia organizacji, fizjologii i techniki zabezpieczającej. Rozwój technologiczny podniósł efektywność działania nurków i wykonywania prac podwodnych, ale spowodował konieczność podwyższenia kwalifikacji personelu ekipy nurkowej. Ostatnie dziesięciolecie charakteryzuje się wprowadzeniem jakościowo nowego sprzętu nurkowego, w którym wiodącą rolę odgrywa komputer nurkowy oraz szerokie wprowadzenie lekkiego sprzętu niezależnego do prac podwodnych w strefie nurkowań głębokich. W naszym kraju pierwsze nurkowania głębokie były nurkowaniami dla celów militarnych, konkretnie dla celów ratownictwa, Szkolenie pierwszych ekip nurków odbyło się w Polsce w latach siedemdziesiątych.
Despite great progress in the technology relating to the problems of working underwater they still aren't all solved satisfactorily. Mainly because of the necessity to take into consideration the problems associated with organization, physiology and technology. Technological development has raised the efficiency of working divers when executing underwater work, but has caused the need to raise the level of qualifications of the diving team's personnel. The last decade has seen the introduction of improved new diving equipment, in which the computer is playing a leading role. Also the introduction of a wide range of light, independent equipment for use in the field of under-water work in the deep water zone has created a vast improvement in the safety and efficiency of deep sea divers.. In our country the first deep sea diving was for military purposes, specifically for rescue work.. The training of diving teams in Poland was started in the early seventies.

Opis:: Mooring ropes are essential components of ships and offshore floating structures and they are subjected to cyclic axial loads. This study investigates the evolution of the full-cycle stiffness of fibre polyester ropes under long-term static and dynamic loading. First, the static stiffness characteristics of the ropes, including the rope elongation properties at different stages, shrinkage rates, and creep coefficients after an idle period, are examined under static loads; an empirical formula for static stiffness is established. Second, the dynamic stiffness characteristics of the ropes are investigated under cyclic loads that are typical of platform production operations. The stabilities of the structure under different tensions are compared; the effects of mean tension, tension amplitude, and load cycle on the dynamic stiffness of the ropes are analysed and an empirical formula is established to predict the dynamic stiffness during the engineering design phase. The results of this study can be helpful for the rational design of deep-sea taut-leg mooring systems because they present the evolution of the full-cycle stiffness characteristics of mooring ropes.

Opis:: Aerosol fluxes from the sea surface are one of the important factors determining the dynamics of the air-sea interaction. Not numerous available data showed that the intensity of aerosol fluxes strongly depends on the intensity of wave breaking. In the paper theoretical formulas to determine the probability of breaking crests and percentage of whitecaps coverage are discussed. These formulas are a starting basis for the set-by-step procedure to determine the aerosol fluxes in deep water under the steady sea state conditions.

Opis:: An acoustic sea glider has been developed for ambient sea noise measurement and target detection through the deployment of an acoustic vector sensor (AVS). The glider was designed with three cabins connected in sequence and it can dive to depths exceeding 1200m. The AVS fixed on the glider measure acoustic pressure and particle velocities related to undersea noise, and the inner attitude sensors can effectively eliminate the estimation deviation of the direction of arrival. The inherent self-noises of the acoustic sea glider and AVS are presented respectively in respect to the Knudsen spectra of sea noise. Sea trial results indicate that the AVS could work well for undersea noise measurement when the glider is smooth sliding, and the target azimuth estimated by AVS after correction is remarkably consistent with the values measured by the GPS, and direction-finding errors are less than 10 degrees. The research in this paper shows that the acoustic sea glider is able to undertake tasks such as a wide range of underwater acoustic measurement and detection.

Opis:: Soft-sediment deformation structures (SSDS) are widespread in the upper part of the S. Mauro Formation (Cilento Group, Middle-Late Miocene). The succession is represented mainly by thick and very thick, massive, coarse-grained sandstones, deposited by rapid sedimentation of high-density turbidity currents. The most common SSDS are short pillars, dishes, sedimentary sills and convolutions. They occur mostly in the upper parts of sandstone beds. Vertical tubes of 4–5 cm in diameter and up to 50 cm long constitute the most striking structures. They begin in the middle part of sandstone beds, which are basically massive or contain faint dish structures. These tubes can bifurcate upwards and/ or pass into bedding-parallel veins or dikes. The vertical tubes sometimes form sand volcanoes on the then sedimentary surface. The SSDS are interpreted as the result of earthquake-triggered liquefaction and/or fluidisation of the turbidites that were affected by the seismic shocks. This implies that the deformed layers should be considered as seismites.

Opis:: The investigation within the framework of this study was carried out on three marine species fished off in Moroccan coasts, namely: a fish, the sole (Solea Vulgaris), a cephalopod, the cuttlefish (Sepia Officinalis) and a crustacean, the pink shrimp (Parapenaeus Longirostris). The aims of this study were assessing the level of concentration in these three marine species, of three metallic trace elements: lead (Pb), cadmium (Cd) and mercury (Hg) and giving a reflection on the way in which Moroccan deep-sea fishing professionals can join a food safety management system to ensure the safety of their product and promote their competitiveness. Sampling was carried out at the port of Agadir city after landing of the deep-sea fishing boats which operate beyond 10 nautical miles, offshoring the seabed of Agadir for pink shrimp (Parapenaeus Longirostris), and in Dakhla city offshore for sole (Solea Vulgaris) and cuttlefish (Sepia Officinalis). Trace metal analysis was performed on individual muscles belonging to the three species. The results of the conducted investigations show that the Pb content varies between 0.01 ppm and 0.27 ppm in Solea Vulgaris; between 0.015 ppm and 0.16 ppm in Sepia Officinalis and between 0.022 ppm and 0.38 ppm for Parapenaeus Longirostris. For Cd, the concentrations vary between 0.0047 ppm and 0.050 ppm in Solea Vulgaris; between 0.0025 ppm and 0.254 ppm in Sepia Officinalis and between 0.0065 ppm and 0.11 ppm in Parapenaeus Longirostris. Concerning Hg, the contents vary between 0.0006 ppm and 0.075 ppm in Solea Vulgaris; between 0.0008 ppm and 0.05 ppm in Sepia Officinalis and between 0.0016 ppm and 0.09 ppm in Parapenaeus Longirostris. It appears from this study that the metal contents detected at the level of the three species of seafood investigated are below the regulatory thresholds. These results can be considered as the first basis for validating the control measure linked to the absence of metallic contamination of the three species in the sites studied.

Opis:: Upper Cretaceous to lower Palaeogene carbonate and siliciclastic deposits that crop out widely in the Haymana and Polatlı districts (Ankara Province) of the Haymana Basin (Central Anatolia) are rich in larger benthic foraminifera, various macrofossils and ichnofossils. The ichnofossils of the Haymana and Yeşilyurt formations were studied at five localities. The Upper Cretaceous siliciclastics of the Haymana Formation contain moderately diverse trace fossils, belonging to the deep-sea Nereites ichnofacies. The Paleocene siliciclastic and carbonate deposits of the Yeşilyurt Formation comprise similar trace fossils, which do not show significant changes in comparison to the Haymana Formation. This indicates that the K-Pg boundary extinction event did not affect the ichnofauna with any longer consequences. The Upper Cretaceous coarser, siliciclastic deposits of the Haymana and Beyobası formations are rich in shallow-marine, larger benthic foraminifera, including species of Orbitoides, Omphalocyclus, Siderolites, Hellenocyclina, and Loftusia, whereas fine siliciclastic deposits contain abundant planktonic, open-marine foraminifera, such as Globotruncana and Heterohelix. Palaeogene siliciclastic to carbonate deposits of the Kartal, Yeşilyurt and Çaldağ formations are rich in the larger, benthic foraminifera Nummulites, Discocyclina, Assilina and Alveolina. The larger foraminifers have been redeposited from nearby, shallow-marine parts of the basin.

Opis:: Within this work we present a first experimental setup of a high-resolution real-timecapable 3D sonar camera system for deep sea operation. Since we are currently in the development process, the focus of this work is on the transmission aspects of the camera. Following publications will include the receiving aspects as well as the first phantom reconstructions. The system consists of a 1024 element matrix array antenna, together with a 128 channel beamforming system including a 1:8 multiplexing device for each channel. The camera is supposed to deliver volumetric images within a range of up to 15 m in a deep sea environment up to 6000 m depth. The antenna provides the advantage of an adjustable defocused transmitting sound field. This allows dynamic control of the field of view, and an increase of the image contrast for a specific region.

Konwencja Narodów Zjednoczonych o prawie morza wielokrotnie podkreśla konieczność ochrony ekologicznego i ekonomicznego interesu obecnych i przyszłych pokoleń przy prowadzeniu działalności wydobywczej w obszarze dna morskiego. W świetle coraz bardziej rychłej perspektywy rozpoczęcia działalności wydobywczej w obszarze dna morskiego morza pełnego konieczną staje się refleksja nad stopniem przygotowania Międzynarodowej Organizacji Dna Morskiego do realizacji swoich funkcji w zakresie reprezentowania interesu ludzkości.
The concept of intergenerational justice is deeply rooted into the regulation of activities in the Area. United Nations Convention on the Law of the Sea on many occasions stresses the need to protect the marine environment in the interest of both contemporary and future generations. One of the institutions with vast competences in this field is the International Seabed Authority. With a perspective on inevitable commercial exploration and exploitation of seabed resourcesthere is a need to answer the question if the Seabed Authority is properly prepared both in the field of law and policy to act as a steward of a mankind?Which instruments has been developed to ensure sustainable use of seabed resources and which of them are at the disposal of the International Seabed Authority? Finally, are the standards of the protection of seabed environment sufficient to satisfy the needs of contemporary consumption without diminishing the ability of the mankind in the future to freely choose their path of development? We can assume that environmental standards which would protect the interest of future people would also secure the sustainability in contemporary use of common heritage at the Seas. International Seabed Authority and international law of the sea can play important role in this process by shaping the future of the mankind with actions undertaken today.

Opis:: Trace fossils and lithofacies have been studied for the first time in the Numidian Formation (Upper Oligocene–Lower Miocene) of the Ouarsenis Mountains in Algeria to interpret their depositional environment. Twenty-two ichnogenera have been recognized in eight lithofacies of three main facies associations in four representative sections. Distribution of the trace fossils is dependent on the facies. Most trace fossils are dominated by post-depositional forms (62%) and occur in fine-grained, thin-bedded sandstones of facies F4. They belong to the Ophiomorpha rudis, Paleodictyon and the Nereites ichnosubfacies of the Nereites ichnofacies. The O. rudis ichnosubfacies is recorded in 1) medium- to very thick-bedded sandstones of the facies association FA1, interbedded with thinner sandstone beds of the facies F2 and F4 in the upper unit of the sections studied, which were deposited in channel fill and levee-overbank environments, and in 2) medium- to thin-bedded sandstones of the facies association FA2 in the lower unit of the Kef Maiz and the Ain Ghanem sections, which were deposited in isolated narrow channels within the mud-dominated part of the depositional system and occasionally fed with turbiditic sand. The Paleodictyon ichnosubfacies occurs in thin- to medium-bedded sandstones (FA2) of the lower units in the Ain Ghanem and Kef Maiz sections and the lowest part of the upper unit of the Kef Maiz section, which were deposited in channel margin or foremost channel-to-levee-overbank areas. The Nereites ichnosubfacies is recorded in thin-bedded sandstones (FA2), which were deposited in crevasse-splays or small lobes on a basin floor invaded occasionally by turbidites against a background of pelagic and hemipelagic sedimentation.

Opis:: It is widely accepted that vortex-induced vibration (VIV) is a major concern in the design of deep sea top-tensioned risers, especially when the riser is subjected to axial parametric excitations. An improved time domain prediction model was proposed in this paper. The prediction model was based on classical van der Pol wake oscillator models, and the impacts of the riser in-line vibration and vessel heave motion were considered. The finite element, Newmark-β and Newton‒Raphson methods were adopted to solve the coupled nonlinear partial differential equations. The entire numerical solution process was realised by a self-developed program based on MATLAB. Comparisons between the numerical calculation and the published experimental test were conducted in this paper. The in-line and cross-flow VIV responses of a real size top-tensioned riser in linear sheared flow were analysed. The effects of the vessel heave amplitude and frequency on the riser VIV were also studied. The results show that the vibration displacements of the riser are larger than the case without vessel heave motion. The vibration modes and frequencies of the riser are also changed due to the vessel heave motion

Opis:: Ophiurites crinitus is a fossil brittle−star species which passed largely unnoticed since its original description. In this paper, we redescribe the type material of O. crinitus with the aim to put it into the context of modern ophiuroid systematics, and propose the new genus name Ophiosternle to replace the invalid Ophiurites. The re−assessed species is shown to be a member of the extant deep−sea family Ophiacanthidae, articulated fossils of which are extremely rare. It presents greatest affinities with members of the Ophioplinthaca–Ophiocamax–Ophiomitra clade, of which it most probably represents the oldest known fossil species. The depositional environment of the strata, which yielded the described specimens is interpreted as shallow, storm−influenced marine setting in the immediate vicinity of coral reefs. This contrasts with the distribution pattern of extant species of the Ophioplinthaca–Ophiocamax–Ophiomitra clade, which almost exclusively occur at depths exceeding the shelf break.

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:: Monitoring toxic metal concentrations in fish is very important for human health because fish, which are consumed by humans, can accumulate toxic metals from water up to hazardous levels. The aim of this study has been to monitor the levels of Cd, Pb, Cu, Cr and Ni in three deep-sea fish species as well as to make a risk assessment of their consumption. The samples were digested in a microwave oven and the determinations were made by atomic absorption spectrophotometry (AAS) and inductively coupled plasma-atomic emission spectrophotometry (ICP-AES). The mean lead concentrations in the Salmo salar and Sarda sarda species were found to be 955 and 948 μg kg-1, respectively, and these levels are three-fold higher than the risk threshold level of 300 μg kg-1. Cd concentrations in only six samples were slightly higher than the maximum allowable concentrations (MACs) of 100 μg kg-1. Mean Cr and Ni concentrations in Salmo salar were found to be 866 and 472 μg kg-1, respectively, and these results were higher than in Sarda sarda (mean 388 μg Cr kg-1 and 356 μg Ni kg-1) and Merlangius merlangus (mean 303 μg Cr kg-1 and 336 μg Ni kg-1). The measured Pb concentrations in all muscles of Salmo salar and Sarda sarda were found to be significantly higher than the MAC values, while Cd in all studied samples was around or lower than the MACs. However, there is no carcinogenic risk for humans, and the risk of developing cancer over an average human lifespan is between 2.5 and 13 in 1,000,000.

Tematy:: nonlinear parameter of low saline seawater
properties of Baltic Sea
Opis:: The properties of the nonlinear phenomenon in water, including sea water, have been well known for many decades. The feature of the non homogeneous distribution of the speed of sound along the depth of the sea is very interesting from the physical and technical point of view. It is important especially in the observation of underwater area by means of acoustical method (Grelowska et al., 2013; 2014). The observation of the underwater space has been carried out for more than hundred years. In the second half of the twentieth century we observed very intense trend of development of the measuring methods of underwater sound speed. It was done mainly in the linear sound propagation aspect. At the end of 20th century nonlinear devices were invented. Thus, from this point of view, knowledge on the nonlinear properties of the sea water is the matter of interest. The phenomenon of nonlinear distortion of elastic waves, and the same the efficiency of nonlinear transfer of energy from the primary wave to the higher harmonic components depend on properties of the medium, especially on the material constant known as the nonlinearity parameter B/A. The Baltic Sea is a specific reservoir with untypically low salinity and low depth (Grelowska, 2000). In the paper results of investigation of nonlinear properties of the South and the Central Baltic by means of thermodynamic method are presented.

Opis:: This article reports on the first detailed study of the Skole Nappe’s Ropianka Formation in the Słonne outcrop section along river San. Lithological and micropalaeontological similarities indicate that the sedimentary succession correlates with the formation’s Wiar Member of Campanian–late Maastrichtian age. The sedimentary succession, more than 140 m thick, is interpreted as a deep-marine complex of turbiditic depositional lobes and the study reveals its sedimentary anatomy. Six component facies of sediment gravity-flow deposits and their stratigraphic grouping into four facies associations are recognized, with these latter considered to represent deposits of the lobe axial zone, lateral flank zone and featheredge fringe zone, as well as an interlobe outer-fringe zone. Semi-quantitative characterization and comparison of facies associations gives insight into the succession’s sedimentary heterogeneity. Six depositional lobes superimposed upon one another are recognized in the stratigraphic succession, and their pattern of vertical stacking is interpreted in terms of dynamic stratigraphy on the basis of the upward succession of facies associations. The stratigraphic arrangement of facies associations is attributed to autogenic morphodynamic changes within the evolving depositional system, although it cannot be precluded that also eustatic and local tectonic forcing came into play. The case study sheds more light on the sedimentary environment, sediment sourcing system and spatial depositional pattern in the Late Cretaceous Skole Basin, where the aggrading seafloor apparently oscillated around the lysocline depth that could be mid-bathyal at that time.

Opis:: We present a systematic study of thyasirid bivalves from Cretaceous to Oligocene seep carbonates worldwide. Eleven species of thyasirid bivalves are identified belonging to three genera: Conchocele, Maorithyas, and Thyasira. Two species are new: Maorithyas humptulipsensis sp. nov. from middle Eocene seep carbonates in the Humptulips Formation, Washington State, USA, and Conchocele kiritachiensis sp. nov. from the late Eocene seep deposit at Kiritachi, Hokkaido, Japan. Two new combinations are provided: Conchocele townsendi (White, 1890) from Maastrichtian strata of the James Ross Basin, Antarctica, and Maorithyas folgeri (Wagner and Schilling, 1923) from Oligocene rocks from California, USA. Three species are left in open nomenclature. We show that thyasirids have Mesozoic origins and appear at seeps before appearing in “normal” marine environments. These data are interpreted as a record of seep origination of thyasirids, and their subsequent dispersal to non-seep environments. We discuss the age of origination of thyasirids in the context of the origin of the modern deep sea fauna and conclude that thyasirids could have deep sea origins. This hypothesis is supported by the observed lack of influence of the Cretaceous and Paleogene Oceanic Anoxic Events on the main evolutionary lineages of the thyasirids, as seen in several other members of the deep sea fauna.

Opis:: Thirty-five near-surface sediment samples were recovered from the continental shelf and upper slope regions of the north-western (NW) Gulf of Mexico. The geochemical data of the sediments recovered were examined to investigate the weathering intensity, provenance, palaeo-oxygenation condition, and level of heavy metal contamination. The sediments analysed showed a moderate to high intensity of chemical weathering. Major and trace element concentrations indicated a terrigenous origin, closely related to the weathering of rocks rich in aluminosilicates. The results of this study further revealed that major rivers, the Bravo and Soto La Marina, played an important role in delivering sediments to the study area. The concentration of transition trace elements such as Cr, Cu, Ni, and V revealed that the sediments were derived from intermediate rocks such as andesite. The V/Cr, Ni/Co, and Cu/Zn ratios in the sediments were <2, <5, and <1, respectively, suggesting a depositional process occurred under well-oxygenated conditions. Principle Component Analysis (PCA) did not show a significant difference in sediment texture between the continental shelf and slope areas. The enrichment factor (EF) and Geo-accumulation index (lgeo) values were <2 and <1, respectively, suggesting the absence of an anthropogenic input.

Opis:: The dynamics of climatic conditions during the Holocene in the Sumba Strait is not well known, compared with in the Indian Ocean. The aim of this paper is to identify the possible Holocene climate dynamics in Sumba Strait, eastern Indonesia by using deep-sea core sediments. A 243 cm core was taken aboard RV Baruna Jaya VIII during the Ekspedisi Widya Nusantara 2016 cruise. The core was analyzed for elemental, carbonate and organic matter content, and abundance of foraminifera. Based on geochemical and foraminifera data, we were able to identify at least six climatic changes during the Holocene in the Sumba Strait. By using the elemental ratio of terrigenous input parameter, we infer to interpret that the precipitation in the Sumba Strait during the Early Holocene was relatively higher compared with the Mid to Late Holocene.

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:: The Markov chains procedure was applied to the study on the sequences of lithofacies and depositional intervals in the Godula Beds (Turonian-Lower Senonian) of the Flysch Carpathians. The model (depositional) and modal (a most frequent in profile) diagrams were constructed and corresponding sequences were recognized. It was found that deposition from high-density turbidity currents of variable retardation rates was the dominating mechanism whereas the low-density turbidity currents were rather rare. The newly deposited sediments were commonly eroded by the succeeding, dense currents. Deposition processes were dominated by the two clearly separated environments: channels and depositional lobes. Their systems were subjected to frequent changes due to lateral migration caused by tectonic movements (uplift of cordilleras and subsidence of sea floor) and eustatic changes of sea level.

Opis:: The depletion of inland deposits of natural resources and the increasing demand for some raw materials have resulted in the growing interest in deep sea exploitation of natural deposits. This gives an impulse to the mounting research and development of methods of exploitation of natural deposits from the sea and ocean floors, which are not limited to petrol and gas. The main area of difficulty in opencast mining methods conducted at considerable depths is the transportation process from the sea floor to the surface. The methods employed so far, such as continuous line bucket (CLB), hydraulic pumping (HP) and air-lift pumping (ALP), have both advantages and disadvantages. The most salient problem is their considerable energy consumption resulting in great costs, hence the need for the development of less expensive methods. The authors have suggested a new method, involving the use of pyrotechnical materials as a source of energy in the transportation from the sea floor and have presented its theoretical grounding. Special emphasis has been placed on determining the depth to which the method can be applied and the energy needed in transportation in relation to the density of the transported substance (output).

Opis:: Trace fossils collected from the best outcrop of the Kamchia Formation have been analysed. There are thirteen ichnotaxa (Curvolithus simplex, Gyrochorte isp., ?Helminthoidichnites tenuis, Multina minima [second occurrence], Palaeophycus tubularis, ?Palaeophycus isp., Phycodes bilix, Phycosiphon incertum, Planolites cf. reinecki, Spongeliomorpha ?chevronensis, Squamodictyon tectiforme, Thalassinoides suevicus, Zoophycos isp.) representing different ethologic, toponomic and preservational types, and produced at different depths in the sediment. The ichnoassemblage contains a mixture of forms typical of flysch (Squamodictyon) and shelf deposits (Curvolithus, Gyrochorte). Probably, sediments of the Kamchia Formation were deposited in an offshore or deeper basin with storm deposition of sand beds and background marly sedimentation. It is possible that storm currents transported trace makers of the shelf trace fossils to the deeper sea. It is not excluded that the trace maker of Gyrochorte migrated to the deep-sea after the Jurassic. However, the simplest explanation is that the Kamchia ichnofauna represents an ecological transition between shelf and slope communities.

Opis:: Two ammonites Teschenites subflucticulus Reboulet and Criosarasinella mandovi Thieuloy have been found for the first time in the Flysch Carpathians. They occur in the so far poorly dated Early Cretaceous flysch deposits of the Silesian Nappe at Poznachowice Dolne, in the Upper Cieszyn Shale and the Hradiště (Grodziszcze) beds lithotypes, respectively. Teschenites subflucticulus points to Late Valanginian (Furcillata Zone), but nanno- plankton points to Late Hauterivian-Late Barremian and dinocysts to Late Hauterivian, all analyzed from the same sample. Criosarasinella mandovi points also to Late Valanginian (Furcillata Zone), what is not in contra-diction with the nannoplankton assemblage (Early Valanginian-Early Barremian) analyzed from the same bed, but dinocysts suggest Late Hauterivian. Preservation of the ammonites and sedimentary features of their host beds exclude redeposition. The difference in age by almost 3 Ma years between the ammonites and microfossils cannot be satisfactorily explained according to the current knowledge on their biostratigraphic meaning; it is left as it is as a dilemma.

Opis:: A strain of marine amoeba has been isolated and studied from the bottom sediments of the Great Meteor Seamount (Atlantic Ocean, 29°36.29′N; 28°59.12′W; 267.4 m deep). This amoeba has a typical dactylopodiid morphotype, a coat of delicate, boat-shaped scales, and a Perkinsela-like organism (PLO), an obligatory, deeply-specialized kinetoplastid symbiont near the nucleus. These characters allow us to include this species into the genus Paramoeba. However, it differs from its only described species, P. eilhardi, in the structure of scales. P. atlantica n. sp. is established therefore to accommodate the studied strain. SSU rRNA gene sequence analysis suggests that P. atlantica belongs to the Dactylopodida, and is sister to a monophyletic clade of P. eilhardi and all Neoparamoeba spp., branching separately from P. eilhardi. Therefore, the genera Paramoeba and Neoparamoeba, currently defined based on the cell surface ultrastructure, might be paraphyletic and probably should be synonymized, as further evidence is accumulated. Based on the data available we emend the families Vexilliferidae and Paramoebidae to make them more consistent with the current phylogenetic schemes.

Opis:: Geochemical studies (WD-XRF, ICP-MS, and GF-AAS) have shown that polymetallic nodules from the eastern Clarion-Clipperton Zone (CCZ) in the Pacific Ocean are enriched in several metals such as Cu (mean 1.16%), Ni (1.15%), Co (0.15%), and Zn (0.14%), as well as remarkable contents of Mo (0.059%), V (0.04%), Ce (0.019%), Nd (0.011%), Li (0.015), and Pt (43 ppb). The average content of REE, together with Y and Sc, is 620 ppm. In nodules from the CCZ metal concentrations are often much higher than those reported in nodules from other ocean basins in the world. The bulk-nodule mean value of the Mn/Fe ratio is 5.3, which is characteristic for a mixed (hydrogenetic and diagenetic) origin of the nodules. Microprobe investigation revealed two different chemical compositions of the layers, and ascertained their general metal content. The nodules analyzed are composed mainly of concentric-collomorphic laminae of Mn and Fe (oxy)hydroxides which crystallized around mineral nuclei (e.g., quartz, clay minerals), bioclasts or rock fragments. They are from 3.3 to 7.6 cm in diameter. The chemical and physical properties of the laminae allowed distinction of two genetic types: hydrogenetic and diagenetic. Those formed as a result of hydrogenesis had increased values of Co, Si, Cl and S, while formed diagenetically showed increased levels of Cu, Ni, Mg, Zn and K. These lamina types are characterized by different growth structures, reflectivity, density and Mn/Fe ratios. The ratio of the diagenetic layers to hydrogenetic layers (192/53) in representative polymetallic nodules shows that the nodules of this study are of mixed hydrogenetic-diagenetic type. A mixed genesis was also shown by discriminant diagrams, with these CCZ samples being located at the transition between typical hydrogenetic and diagenetic fields.

Opis:: Sodium and ammonium jarosite precipitates from the sulfuric acid leaching of deep-sea nodules were converted into well crystallized hematite by alkali decomposition of jarosite using sodium hydroxide or ammonia solutions at different temperature and subsequent sintering at 400 and 750°C. The obtained sodium and ammonium jarosite precipitates were intergrown aggregates composed of half-prism and tabular-like crystals with sharp corners and edges. It was found that base-strength of alkali solutions effected the kinetics of conversion reactions and morphology of solid phase. The residual solids retained the shape and the particle size of the original jarosite precipitates. The main feature of the residual from sodium jarosite is a severe surface pitting and an erosion of edges and corners. The decomposition of ammonium jarosite precipitates at different temperatures took place very fast and completed within 15 minutes at 25°C. Increasing temperature increased the decomposition rate. At 60°C jarosite decomposition was completed in less than 2 minutes. But the experimental results indicated that the sulfate anions slowly diffused from the jarosite structure after the completion of the decomposition reaction. The main impurities in jarosite precipitates such as Mn, Cu and Ni reported into the final product but hematite obtained from decomposition of ammonium jarosite contained significantly less Cu due to formation of copper ammonia complex. The XRD analysis results indicated that the decomposition products at temperatures lower than 90°C are amorphous. At 90°C the decomposition products consisted of poorly crystallized hematite. After sintering the decomposition products from both sodium and ammonium jarosites at 400°C and 750°C, well-crystallized hematite was obtained.
Sodowy i amonowy jarosyt wytrąca się podczas ługowania kwasem solnym guzków głębinowych i zostaje przetworzony w wyraźnie skrystal-izowany hematyt za pomocą dekompozycji alkalicznej jarosytu, która zachodzi przy użyciu wodorotlenku sodu lub roztworów amonowych w różnych temperaturach oraz następujących potem procesów spiekania w 400 i 750°C. Uzyskane wytrącenia sodowego i amonowego jarosytu utworzyły następnie skupienia złożone z pół-pryzmatycznych i tabularycznych kryształów o ostrych końcach i krawędziach. Stwierdzono, że siła roztworów alkalicznych wpływa na kinetykę reakcji konwersji oraz morfologię fazy stałej. Pozostałe części stałe utrzymały kształt i wielkość ziaren oryginalnego wytrącenia jarosytu. Główną cechą reszt z sodowego jarosytu są wżery powierzchniowe oraz erozja krawędzi i końców. Dekompozycja wytrąceń jarosytu amonowego zachodzi bardzo szybko w innej temperaturze. Zajmuje to nie więcej jak 15 minut w temperaturze 25°C. Wzrost temperatury powoduje wzrost stopnia dekompozycji. W temperaturze 60°C dekompozycja jarosytu została ukończona w czasie mniejszym niż 2 minuty. Jednakże, wyniki eksperymentu wskazały, że aniony siarczanowe ulegają powolnej dyfuzji ze struktury jarosytu po ukończeniu reakcji rozkładu. Głównymi zanieczyszczeniami w wytrąceniach jarosytu są takie pierwiastki jak Mn, Cu oraz Ni, których obecność stwierdzono w finalnym produkcie. Jednak hematyt otrzymany w wyniku dekompozycji jarosytu amonowego zawierał znacznie mniej Cu ze względu na utworzenie kompleksu amonowego miedzi. Wyniki analizy XRD wykazały, że produkty rozkładu w temperaturze niższej niż 90°C są amorficzne. W temperaturze 90°C produkty rozkładu zawierały słabo skrystalizowany hematyt. Po spiekaniu produktów rozkładu z zarówno sodowego, jak i amonowego jarosytu w temperaturach 400°C oraz 750°C otrzymano dobrze skrystalizowany hematyt.

Opis:: The palaeolake from Ossówka, eastern Poland, is an unusual example of basin, in which sedimentation lasted from the beginning of the Holsteinian through several climatic oscillations until the Early Saalian, i.e. over a period of ~70,000 years. This provides us with the opportunity of correlating the dynamically changing events on land with their potential equivalents in the marine profiles. Alkenone-based temperature reconstructions using Uk’37 are an unusual tool in this respect. Nevertheless, as a result, we successfully relate this pollen sequence to the changing SST (sea surface temperature) values in the colder phases of MIS 11. The bipartite Ferdinandovian Interglacial was previously correlated with the upper part of the Cromerian complex (MIS 13 and MlS 15). Having at our disposal limits in the SST alkenone-based record, we clearly identify the stratigraphic position of the second warm phase of MIS 15 and a small fragment of MIS 14. In our opinion, the Rhume Interglacial, identified in Germany, should be located within MIS 13. Using the available orbitally tuned chronology, we also give a substantial input to estimate duration of these terrestrial interglacials, indicating the starting and ending points of their equivalents in the alkenone records.

Opis:: In this article the authors discuss the concept of using pyrotechnical materials for transportation in deep sea environment. The use of pyrotechnical materials in underwater transportation involves their use as a source of energy (needed, for instance, in emptying the ballast tank). The authors presented the experimental verification of the usefulness of pyrotechnical materials in transporting from great depth. In the experiments, a modified composition black powder was used as source of energy. In the research the authors focused on two methods of controlling the pyrotechnical reaction effects, i.e., mechanical suppression of the blast, so as to reduce its negative effect on the housing of the transporter, and control of the pyrotechnical reaction itself. The obtained results confirm the possibility of using pyrotechnical materials in transportation of deposits from considerable depth.

Opis:: This study reports on a new set of sedimentological data and related interpretations of the Santonian–Campanian siliciclastic deposits in the Western Flysch Carpathians based on natural outcrops in the uppermost Godula Formation and lowermost Istebna Formation. The rationale was to confront the characteristics of this flysch succession with current controversies and state of knowledge on deep-water clastic sedimentation. The sedimentological analysis of the field data allowed for multi-scale synthetic classifications of the depositional components in the investigated flysch. The hierarchical and practical nature of the suggested classification schemes allows for their application to similar deposits in other regions. The siliciclastic deposits are products of gravity-driven terrigenous sediment redeposition via submarine slumps, debris flows, and turbidity currents. Sediment reworking by tractional bottom currents is considered as an accompanying factor. Point-sourced turbiditic fan lobe fringes from the submarine piedmont ramp and linearly supplied debritic covers along the slope apron are proposed as dominant. The innovative linking between the textural-structural descriptive features of the deposits and the critical determinants of specific sediment gravity-flow processes and architectural elements of the deepwater clastic depositional systems is a significant contribution to this research field.

Opis:: Flysch deposits of the Ropianka Formation (Wiar and Leszczyny members; Skole Nappe) at Wola Rafałowska include two different sediments that contain exotic pebbles, cobbles and boulders. The first one is a graded conglomerate that contains mostly cobbles of sandstones, gneisses, Štramberk-type limestones, volcanic rocks, pegmatites and ferruginous siltstones. The second one is a pebbly mudstone that contains clasts of sandstones, stone coal, grey mudstones, volcanic rocks, schists, limestones, marls, black mudstones, conglomerates, volcaniclastic rocks and quartz gravels that are floating within a muddy matrix. Genesis of the conglomerate is unclear because it shows features typical of debris flows (poorly sorted, matrix- to clast-supported, large amount of cobble to boulder fraction) as well as high density turbiditic currents (indistinct normal gradation, small amount of cohesive material, crushed clasts that suggest interaction between grains during transportation and at least partly turbulence during flow). The pebbly mudstone represents typical debris flow deposits (large amount of cohesive material, matrix-supported, poorly sorted, lack of grain gradation and traction structures that suggest laminar flow). Limestones occurring in both exotic-bearing sediments show different Upper Jurassic–lowest Cretaceous facies of a carbonate platform, which was involved in the source area of the Skole Basin, along with its basement. They can be interpreted as deposits of: 1) platform-margin reefs and a platform slope: a) partly silicified coral boundstone, b) microbial-coral boundstone, c) silicified sponge-microbial boundstone grading into peloidal-ooidal grainstone with bioclasts, and d) strongly silicified limestone with intraclasts and bioclasts; 2) deeper, platform slope to toe-of-slope area – bioclastic wackstone; 3) inner platform, including: a) partly silicified wackstone with peloids, small intraclasts and bioclasts, and b) microbial bindstone. Moreover, some exotic clasts are built of Albian–Cenomanian wackstone with abundant sponge spicules and planktonic foraminifers, which are interpreted as deeper shelf sediments. Taking into account the geometry of thrust sheets from the site of the exotic-bearing sediments to the edge of the Skole Nappe, along the most probable transportation path, including tectonic/erosional reduction and different variants of slope inclination, the distance of the mass flows attained at least 25–97 km from the shelf edge.

Opis:: Fan fringe deposits of deep-sea fans are characterised by the Nereites ichnofacies, but in the Miocene Cingöz Formation in southern Turkey they contain 17 ichnospecies typical of the Nereites, Skolithos and Cruziana ichnofacies, including vertical "shallow-water" horn-like forms and Ophiomorpha rudis. Tracemakers of Ophiomorpha rudis have been probably imported by stronger turbidity currents from the inner part of deep-sea fan or occured as a result of gradual colonisation of fan fringe deposits. Similar trace-fossils occurs in related facies of the coeval Marnoso-arenacea Formation in the Northern Apennines. Comparisons with other Cretaceous-Neogene flysch formations show that ichnoassemblages of fan fringe facies are very diverse in general.
Ichnofacja Nereites charakteryzuje utwory otoczenia stożka głębokomorskiego, jednak w utworach otoczenia stożka mioceńskiej formacji Cingöz w południowej Turcji występuje 17 ichnogatunków z ichnofacji Nereites, Skolithos i Cruziana, w tym "płytkowodne" formy w kształcie rogu oraz formy z gatunku Ophiomorpha rudis. Twórcy śladów Ophiomorpha rudis byli prawdopodobnie transportowani przez silniejsze prądy zawiesinowe z wewnętrznej części stożka, lub zasiedlali oni stopniowo środowisko otoczenia stożka. Podobne skamieniałości śladowe występują w pokrewnych facjach równowiekowej formacji Marnoso-arenacea z Apeninów Północnych. Facje otoczenia stożków innych kredowo-paleogeńskich formacji fliszowych charakteryzują się bardzo zróżnicowanymi asocjacjami skamieniałości śladowych.

Opis:: This study combines high-resolution planktonic foraminiferal eco-biostratigraphy and palaeoclimatic data from the high-sedimentation-rate core J PC-26 from the northwestern margin of the Gulf of Mexico (GoM). The eco-biozones recognized (GOMPFE1-12) being correlated with published Mg/Ca-based sea surface temperatures. This updated palaeoclimatic and stratigraphic reference record facilitates correlations with the Greenland ice core events and their climatic relationships, and also provides a solid stratigraphic framework for correlations with other palaeoclimatic and palaeoceanographic records in the circum-GOM/Caribbean region. This multidisciplinary approach underlines the utility of supporting conventional dating methodologies with different constraints, and further reveals a powerful tool for reliably correlating marine records between comparable deep-sea marginal settings and coeval sequences of this region.

Opis:: The first recognition of a tracemaker responding to a temporary shift in the redox boundary is recognized. This is recorded by a new trace fossil, Sursumichnus orbicularis igen. et isp. nov., which is established for mound-like structures on the upper surfaces of sandstone beds from the Borjomi Flysch (upper Paleocene–lower Eocene) in the Lesser Caucasus (Georgia). It is connected with the spatangoid echinoid burrow Scolicia de Quatrefages, 1849 and interpreted as a resting trace of the same tracemaker produced after moving up from a deeper position within the sediment. The resting is caused by an episode of unfavourable conditions related to shallowing of the redox boundary. The trace fossil is a component of the Nereites ichnofacies.

Opis:: Cenozoic deep−water sediments of the Lincoln Creek, Makah, and Pysht formations in western Washington State, USA, contain sunken driftwood and whale bones that were colonized by invertebrates which largely depend on this type of transient habitat. These fossil woodand whale−fall faunules yielded six new mollusk species that appear to have been endemic to these biogenic microhabitats, except for one species which also occurs in cold−seep limestones. The new gastropod species are the neomphalid Leptogyra squiresi, the buccinid Colus sekiuensis, the allogastropod Xylodiscula okutanii, and the new bivalve species are the protobranch “Nuculana” posterolaevia, the mytilid Idas? olympicus, and the heterodont Thyasira xylodia.

Ciągły rozwój tych komputerów, szczególnie w ostatnich dekadach naszego wieku, dotyczył nurkowań głębinowych realizowanych w nurkowaniach technicznych i rekreacyjnych. Nurkowania głębinowe są trudne i ryzykowne w realizacji z punktu widzenia podwodnej fizjologii oraz realizacji dekompresji. Charakteryzując dekompresję nurka, realizowaną przy pomocy komputera dla nurkowań głębinowych, autor porównuje realizację dekompresji w profesjonalnych nurkowaniach głębinowych. Wskazuje on też na przeszkody formalne i techniczne na drodze wdrożenia komputerów osobistych nurka. W podsumowaniu artykułu ocenia zaś możliwość zastosowania komputera nurkowego w realizacji podwodnych prac głębinowych.
In the article the author presents the specificity of deep diving decompression in relation to the revolution in diving which was triggered by the introduction of a personal computer in recreational diving. Continuous development of these computers, especially in the last decades of our century, concerned deep-sea technical and recreational dives. Deep-sea dives are difficult and risky in terms of underwater physiology and decompression. In characterizing the decompression of a diver, realized with the use of a computer for deep-sea dives, the author compares the realization of decompression in professional deep-sea dives. He also points out the formal and technical obstacles to the implementation of personal dive computers. In summary, the article evaluates the possibility of using the diving computer in the implementation of underwater works.

Opis:: The article focuses on the adaptation and acculturation of Vietnamese immigrants in the Polish society. Specifically, it concentrates on the situation of young Vietnamese women. It is based on analysis of 22 regular interviews and supplementary informal conversations with young Vietnamese immigrants in Warsaw conducted between 2007 and 2012. The author stresses the psychological problems and internal conflicts brought about by the process of adapting to Polish ways of living and thinking. The researched group was composed of 1.5 and second generation of Vietnamese who either were born in Poland, or grew up here from an early age. The situation of these young people, in particular of young women, grows on profound differences between expectations addressed to them in the Vietnamese society from which they come from, and the Polish culture in which they chose to or must live. Many Vietnamese norms are deeply inculcated and internalised – for instance those connected with having children, especially sons or those connected with the higher position of the older generation. At the same time, young Vietnamese immigrants find various Polish normative solutions much more attractive and favourable, for instance giving more freedom to girls by Polish parents, equal relations between men and women (especially between spouses and between parents and children).
