Abstract. The seasonal characteristics of the circulation in the North Aegean Sea are examined with the aid of a climatological type simulation (three-year run with perpetual year forcing) on a fine resolution grid (2.5 km by 2.5 km). The model is based on the Princeton Ocean Model with a parameterisation of plume dynamics that is employed for the input of waters with hydrographic properties that are different than the properties of basin waters, as the Black Sea Water (BSW) outflow through the Dardanelles Strait and riverine sources. The model is nested with a sequence of coarser regional and basin-wide models that provide for the long-term interaction between the study area and the Eastern Mediterranean at large. The results are employed to discuss the response of the North Aegean to the important circulation forcing mechanisms in the region, namely wind stress, heat and salt fluxes, buoyancy due to rivers and the BSW outflow (which is low in salinity and occasionally low in temperature) and the interaction with the Southern Aegean. The high resolution allows for the detailed representation of the complicated topography that presides in the region. This helps produce a rich eddy field and it allows for variability in the pathways of BSW that has implications in the basin hydrography and circulation.Key words.

Abstract. The present study deals with the implementation of an eddy resolving model of the Levantine and Aegean basins and its one-way nesting with a coarse resolution (1/8° × 1/8°) global Mediterranean general circulation model. The modelling effort is done within the framework of the Mediterranean Forecasting System Pilot Project as an initiative towards real-time forecasting within the eastern Mediterranean region. The performed climatological runs of the nested model have shown very promising results on the ability of the model to capture correctly the complex dynamics of the area and at the same time to demonstrate the skill and robustness of the nesting technique applied. A second aim of this study is to prepare a comprehensive climatological surface boundary conditions data set for the Mediterranean Sea. This data set has been developed within the framework of the same research project and is suitable for use in ocean circulation models of the Mediterranean Sea or parts of it. The computation is based on the ECMWF 6-h atmospheric parameters for the period 1979–1993 and a calibrated set of momentum and heat flux bulk formulae resulted from previous studies for the Mediterranean region.

Abstract. A statistical technique for image processing, the maximum cross correlation (MCC) method, was utilized on sequences of NOAA-AVHRR thermal data in order to explore the surface advective current dynamics at the discharge region of the Hellespont in the North Aegean Sea. A 2D numerical flow model was also used in order to simulate the barotropic flow pattern of the surface water layer. The model was forced with diurnal wind fields obtained for the same period as the satellite infrared images. The currents (magnitude and direction) derived from the two methods compare satisfactorily despite the fact that some model simplifications were made.

Slab tearing induces localized deformations in the overriding plates of subduction zones and transfer zones accommodating differential retreat in back-arc regions. Because the space available for retreating slabs is limited in the Mediterranean realm, slab tearing during retreat has been a major ingredient of the evolution of this region since the end of the Eocene. The association of detailed seismic tomographic models and extensive field observations makes the Mediterranean an ideal natural laboratory to study these transfer zones. We review in this paper the various structures in back-arc regions differential retreat from the Alboran Sea to the Aegean-Anatolian region and discuss them with the help of 3D numerical models to better understand the partitioning of deformation between high-angle and low-angle faults, as well as the 3-D kinematics of deformation in the middle and lower crusts. Simple, archetypal, crustal-scale strike-slip faults are in fact rare in these contexts above slab tears. Transfer zones are in general instead wide deformation zones, from several tens to several hundred kilometers. A partitioning of deformation is observed between the upper and the lower crust with low-angle extensional shear zones at depth and complex association of transtensional basins at the surface. In the Western Mediterranean, between the Gulf of Lion and the Valencia basin, transtensional strike-slip faults are associated with syn-rift basins and lower crustal domes elongated in the direction of retreat (a-type domes), associated with massive magmatic intrusions in the lower crust and volcanism at the surface. On the northern side of the Alboran Sea, wide E-W trending strike-slip zones in the brittle field show partitioned thrusting and strike-slip faulting in the external zones of the Betics, and E-W trending metamorphic core complexes in the internal zones, parallel to the main retreat direction with a transition in time from ductile to brittle deformation. On the opposite, the southern margin of the Alboran Sea shows short en-échelon strike-slip faults. Deep structures are not known there. In the Aegean-Anatolian region, two main tear faults with different degrees of maturity are observed. Western Anatolia (Menderes Massif) and the Eastern Aegean Sea evolved above a major left-lateral tear in the Hellenic slab. In the crust, the differential retreat was accommodated mostly by low-angle shear zones with a constant direction of stretching and the formation of a-type high-temperature domes exhumed from the middle and lower crust. These low-angle shear zones evolve through time from ductile to brittle. On the opposite side of the Aegean region, the Corinth and Volos Rift as well as the Kephalonia fault offshore, accommodate the formation of a dextral tear fault. Here, only the brittle crust can be observed, but seismological data suggest low-angle shear zones at depth below the rifts. We discuss the rare occurrence of pure strike-slip faults in these contexts and propose that the high heat flow above the retreating slabs and more especially above slab tears favors a ductile behavior with distributed deformation of the crust and the formation of low-angle shear zones and high-temperature domes. While retreat proceeds, aided by tears, true strike-slip fault system may localize and propagate toward the retreating trench, ultimately leading to the formation of new plate boundary, as shown by the example of the North Anatolian Fault.

The wider area of Attica region and generally the Saronic Gulf contains a significant part of the history and mythology of the ancient Hellenic world. Without overreacting, it could be said that it is one of the most sacred regions of Ancient Greece and perhaps is the only region in the whole world that is related to the birth of so many gods, goddesses and heroes. This fact is linked to the paleo-climatic and geo-environmental changes that have been taken place in the Aegean and Peri-Aegean area and especially in the Saronic Gulf. As it is known, during the last 18000 years, which is after the end of the last glacial period, the climatic changes related to temperature rise had as a consequence the rise of the sea level by 125 m at least. The sea level rise had as a result significant changes in the natural environment and mainly to the distribution of coastlines and coastal areas. The rise of the sea level had also as a result the flooding of closed hydrological basins with changes in their physico-geographical function by changing them initially to lakes and in time to basins. Prehistoric man witnessed these changes in his environment and he attributed them to various gods, sometimes to destructive gods and sometimes to protective ones. All these are mentioned in several myths of Greek mythology. Therefore, the aim of this paper is the correlation of several of those myths with the physicogeographical and geological changes that took place mainly during prehistoric times in order to attempt their interpretation. We will try to approach the mythological relationship of Salamis nymph, the daughter of Asopos river and Metopi, with god Poseidon, in relation to the physicogeographical changes in the greater area between the island of Salamis and Elefsis area during the last 18000 years. The area which, nowadays, is being occupying by the bay of Elefsis. In this area 18.000 years BP there was a closed hydrological basin, which is a morphological depression that did not communicate with the sea, during that time the Saronic Gulf shoreline was located about 30 km away. The data collected up to today do not allow us to say that it was a lake during that period, however, something very possible especially during 10000 BP and 5000 BP. We named this paleo-lake "Kichrea Lake" as a tribute towards Kihreas, the son of Poseidon and Salamis nymph. At this point it is worth mentioning that Salamina and her sister Aegina were both daughters of Asopos river, a river that is located in Aegina Island and that today unfortunately has been renamed to Skoteini stream.

The article presents a general picture of the development of architecture of the Ancient World in the 3nd - 1st millennium BC. identified three main style-making cultures of the Mediterranean (Egypt, Mesopotamia with the Levant, the Aegean world with Antalya) which were formed in 3 thousand BC. and changing trends in the development of their architecture, the birth of the facade composition and its change from plane to spatial, which, according to the author, reveals historical development through architectural form – socio-cultural, worldview changes. At the level of 3 thousand BC. it is possible to state formation of a theme of a monumental portal: in Egypt and in the Mesopotamia. But meaningful construction of the facade, the creation of a presentable facade composition has not yet taken place. from the middle of 2 thousand BC in Egypt and Assyria, symmetrical planar façade compositions were formulated (paired pylons in the temple in Egypt and paired towers at the entrance arch portal in palaces and citadels in Assyria and the Hittites). This architecture stops the visitor not only in its form: small entrance opening against the dominant deaf array presents secrecy, remoteness and elitism of the content of the building. Instead, the traditions of secular open facade with a two-column loggia on the facade denote the megarons of the acropolises of the Aegean world and a bit-hilani house. An echo of such traditions can be considered two-column facades of Georgian traditional folk housing darbazi, which can be considered as characteristic of the region not only of the Caucasus. It should be noted as a change in the ratio of the area of the opening to the plane of the facade indicated the degree of elitism, esoteric or vice versa - democracy of a society and a certain type of building. It is established, as after long stagnation of development and conservation of achieved ideals in schemes of facade compositions noticeable changes occurred around 6-5 centuries. BC, when both in the Aegean region and in Antalya and Persia the formation of the composition of the open facade took place in monumental elite and sacred architecture. Mediterranean architecture opens up, becomes public, social, humane - it is time to form the space of a secular public city square surrounded by columned symmetrical portico facades - time of antique classical architecture.

ABSTRACT Marmara is a small inland sea in Turkey, connected to the Black Sea by the Istanbul Strait (Bosporus) and to the Aegean Sea by the Canakkale Strait (Dardanelles), separating the continents of Europe and Asia; area 11,140 square km/4,300 square mi. In parts it reaches depths of over 1,200 m/3,936 ft. International importance of the Sea of Marmara stands in the forefront even though it is an inland sea of Turkey and it deals with increasing ecological problems for the last 50 years. The Pollution in the Sea of Marmara which threatens all living species cause dramatic falling in fishing potential. Increase in the volume of maritime traffic on the Strait and the Sea of Marmara have increased the risk of the maritime accidents over the years and since 1948 the number of ship accidents have been recorded as around 700. Furthermore, being on the transportation way of hazardous and dangerous materials, pose environmental and safety hazards for the Bosphorus Strait and the Marmara Sea with the surrounding residential areas. The increasing sea traffic also causes considerable congestion on the northern entrance of the Bosphorus Strait. Increase in the volume of maritime traffic on the Bosphorus and Marmara Sea heightens the risk of maritime accidents. In the present work, the risky region of Marmara Sea is chosen for simulation studies. It is assumed that 1000 tonnes of medium crude oil is spilled in the aftermath of a tanker accident. The distribution of oil spill is then determined with respect to time and space by considering 2 different wind directions and scale. The simulation code GNOME™ version 1.2.7 is utilized to generate the oil spill scenarios. As a result of these runs, spillage areas were identified as risky areas and necessary actions to minimize the effect of spill were discussed in the Marmara Sea.

Abstract. As part of the Mediterranean Forecasting System Pilot Project (MFSPP) we have implemented a high-resolution (2 km horizontal grid, 30 sigma levels) version of the Princeton Ocean Model for the southeastern corner of the Mediterranean Sea. The domain extends 200 km offshore and includes the continental shelf and slope, and part of the open sea. The model is nested in an intermediate resolution (5.5 km grid) model that covers the entire Levantine, Ionian, and Aegean Sea. The nesting is one way so that velocity, temperature, and salinity along the boundaries are interpolated from the relevant intermediate model variables. An integral constraint is applied so that the net mass flux across the open boundaries is identical to the net flux in the intermediate model. The model is integrated for three perpetual years with surface forcing specified from monthly mean climatological wind stress and heat fluxes. The model is stable and spins up within the first year to produce a repeating seasonal cycle throughout the three-year integration period. While there is some internal variability evident in the results, it is clear that, due to the relatively small domain, the results are strongly influenced by the imposed lateral boundary conditions. The results closely follow the simulation of the intermediate model. The main improvement is in the simulation over the narrow shelf region, which is not adequately resolved by the coarser grid model. Comparisons with direct current measurements over the shelf and slope show reasonable agreement despite the limitations of the climatological forcing. The model correctly simulates the direction and the typical speeds of the flow over the shelf and slope, but has difficulty properly re-producing the seasonal cycle in the speed.Key words.

Marine transportation in Aegean Sea, a part of the Mediterranean Sea that serves as gateway between three continents has recently seen a significant increase. Despite the commercial benefits to the region, there are certain issues related to the preservation of the local ecosystem and safety. This danger is further deteriorated by the absence of regulations on allowed waterways. Marine accidents could cause a major ecological disaster in the area and pose big socio-economic impacts in Greece. Monitoring marine traffic data is of major importance and one of the primary goals of the current research. Real-time monitoring and alerting can be extremely useful to local authorities, companies, NGO’s and the public in general. Apart from real-time applications, the knowledge discovery from historical data is also significant. Towards this direction, a data analysis and simulation framework for maritime data has been designed and developed. The framework analyzes historical data about ships and area conditions, of varying time and space granularity, measures critical parameters that could influence the levels of hazard in certain regions and clusters such data according to their similarity. Upon this unsupervised step, the degree of hazard is estimated and along with other important parameters is fed into a special type of Bayesian network, in order to infer on future situations, thus, simulating future data based on past conditions. Another innovative aspect of this work is the modeling of shipping traffic as a social network, whose analysis could provide useful and informative visualizations. The use of such a system is particularly beneficial for multiple stakeholders, such as the port authorities, the ministry of Mercantile Marine, etc. mainly due to the fact that specific policy options can be evaluated and re-designed based on feedback from our framework.

While there is increasing interest in the effect of landscape on ancient imagination, less attention has been paid to the impact of restless karst hydrology on ancient beliefs. By identifying shared themes, this study compares and contrasts the way Hittites and Aegean people in the Late Bronze and Early Iron Ages reshaped peripheral karst landscapes into physical and imagined transitional zones. Karst geology underpins much of the Aegean and Anatolian landscape, allowing subterranean zones to be visible and accessible above ground via caves, springs, sinking streams, sinkholes and other unusual natural formations. In both cultures, certain dynamic landscapes were considered to be sacred porous points where deities, daemons, heroes and mortals could transit between cosmic realms. Evidence suggests that Hittites and Aegean people interpreted dramatic karst landscapes as liminal thresholds and spaces situated between the world of humans and the world of deities. Part One investigates physical zones of transition via the karst ecosystems of rural sanctuaries. Part Two considers the creative interpretation in myth and iconography of karst phenomena into metaphysical zones of transition. The examples reveal the way in which Hittites and Aegean people built their concept of the sacred on the extraordinary characteristics of karst geology. Numinous karst landscapes provided validity and a familiar reference point for the creation of imagined worlds where mortal and divine could connect.
Vandag is daar toenemende belangstelling in die effek van die landskap op die verbeelding van die mensdom in die oudheid - maar minder aandag word bestee aan die impak van die rustelose karst landskap op die mens se gelowigheid in die oudheid. Deur die identifisering van sekere gemene temas, vergelyk hierdie verhandeling die manier waarop die Hetiete en die Egeïese volkere in die Laat Brons- en vroeë Ystertydperke die omliggende karstlandskap herskep het in fisiese en denkbeeldige oorgangszones. Die Egeïese en Anatoliese landskap bestaan grotendeels uit karst geologie, met tot gevolg dat ondergrondse zones bo die grond sigbaar en toeganklik is in die vorm van grotte, bronne, sinkgate en ander uitsonderlike natuurlike formasies. In beide bogenoemde kulture is sekere landskapstonele beskou as heilige en poreuse punte waar gode, demone, helde en sterwelinge tussen die kosmiese zones kon beweeg. Die getuienis van die tyd suggereer dat die Hetiete en die Egeïese volkere die dramatiese karst landskappe as grense of drempels tussen hulle wêreld en dié van die gode beskou het. Deel Een ondersoek die fisiese oorgangszones deur te kyk na die karst ecostelsels waarin plattelandse heiligdomme hulle bevind het. Deel Twee beskou die kreatiewe gebruik van karst verskynsels as voorstellings van metafisiese oorgangszones in die gekrewe bronne en ikonografie. Die geselekteerde voorbeelde dui aan die manier waarop die Hetiete en Egeïese volke hulle konsepte van heiligdom gebaseer het op die buitengewone verskynsels van karst geologie. Numineuse karst landskappe het hulle idees gestaaf en ‘n bekende verwysingspunt uitgemaak waar die menslike en die goddelike met mekaar in kontak kon kom.

I-Karst geology isekela kakhulu indawo yezwe i-Aegean ne-Anatolian evumela ukuthi izindawo ezingaphansi komhlaba zibonakale futhi zifinyeleleke ngaphezu komhlaba ngemigede, iziphethu, imifudlana ecwilayo, imigodi yokushona nokunye ukwakheka okungokwemvelo okungajwayelekile. Kuwo womabili amasiko izindawo ezithile eziguqukayo zazithathwa njengezindawo ezingcwele zokungena lapho onkulunkulu, amademoni, amaqhawe nabantu abafayo bengadlula phakathi kwezindawo zomhlaba. Ubufakazi bukhombisa ukuthi amaHeti nabantu base-Aegean bahumusha imidwebo emangazayo yekarst njengemikhawulo yemikhawulo nezikhala eziphakathi komhlaba wabantu nezwe lonkulunkulu. Ingxenye yokuqala iphenya izindawo eziguqukayo zomzimba ngokusebenzisa imvelo ye-karst yezindawo ezingcwele zasemakhaya. Ingxenye Yesibili ibheka ukutolikwa kokudala kunganekwane nakwizithonjana zezinto ze-karst kube izingxenye eziguqukayo zenguquko. Izibonelo ziveza indlela abantu abangamaHeti nabantu base- Aegean abawakha ngayo umqondo wabo ongcwele ngezimpawu ezingavamile ze-karst geology. Amathafa amahle we-karst ahlinzeka ngokusebenza kanye nephuzu elijwayelekile lesethenjwa lokwakhiwa kwamazwe acatshangelwe lapho abantu abafayo nabaphezulu bangaxhuma khona.

Famous for being the location for the writing of the book of Revelation (the Apocalypse), the island of Patmos is a jewel in the Aegean. This small island combines the charm and beauty of a typical Greek island with the tranquility and reverence of a sacred space. Visitors today might very well wish that they, like John, could be sentenced to exile on this island so rich with tradition, faith, and wonder. The northernmost island of the Dodecanese Islands (part of the Southern Sporades chain) in the Aegean Sea, Patmos, a part of the country of Greece, is 22 miles southwest of the island of Samos and about 38 miles from ancient Miletus on the mainland of Turkey. Patmos is a small, mountainous island, about 7 miles long and 3 miles wide, with a ragged coastline. The island has two narrow isthmuses that divide it into three parts. Primarily known for its association with the author of the New Testament book of Revelation, the island today displays the charm of a typical Greek island. The three main towns or villages on the island are Hora, Skala, and Kambos. Patmos is mentioned only briefly by ancient writers (Thucydides, Strabo, Pliny the Elder, and Tacitus), and little is known of its ancient history. The island was settled by the Dorians and later by the Ionians. Ancient ruins on the island attest to the inhabitation of the island during the Hellenistic period, a time when Patmos, along with the islands of Lipsos and Leros, belonged to the territory controlled by Miletus. These islands served as “buffer” islands, guarding and protecting the city of Miletus. Inscriptions from the island provide evidence of a temple of Artemis and a gymnasium on the island. Information about Patmos during the Roman period is scarce. Christian tradition, based on Revelation 1:9, claims Patmos as the site where John was exiled at the end of the 1st century C.E. by the Roman emperor Domitian. Whereas the Roman historian Tacitus does name three other islands in the Aegean (Donusa, Gyarus, and Amorgus) as islands where the Romans exiled or banished political prisoners, Patmos is never mentioned by ancient writers as a place of punishment.
