A numerical model is developed for the exchange of water between the Black Sea and the Marmara Sea through the Bosphorus. An essential part of the modelling procedure is the use of a turbulence energy equation in a scheme of turbulence parametrization. The simultaneous application of a transport equation for the salinity leads to a turbulence suppression term associated with the existence of a strongly stable vertical salinity stratification. Experiments are performed that show how a prescribed difference between the salinities of the Black Sea and the Marmara Sea leads to a basically two-layer flow structure in the model strait. The detailed structure of the flow is complex and involves an intermediate entrainment layer in which there is a system of recirculation that may be expected to play a prominent role in the exchange of water properties between the surface and bottom layers. It is tentatively suggested that the presence of a model sill adjacent to the Marmara Sea may lead to an interpretation of the local flow regime in terms of a stationary internal hydraulic jump phenomenon.

THE UPPER LAYER CIRCULATION OF THE BLACK-SEA - ITS VARIABILITY AS INFERRED FROM HYDROGRAPHIC AND SATELLITE-OBSERVATIONS OGUZ, T; LAVIOLETTE, PE; UNLUATA, U (American Geophysical Union (AGU), 1992-08-15) Quasi-synoptic hydrographic data and satellite imagery are used to describe the circulation and the structural variability of the Black Sea with particular emphasis on the Turkish coast. The circulation is indicated to involve a variable cyclonic circulation with no apparent central locus and a well-defined cyclonic "Rim Current" containing meanders and interacting eddy fields confined to the shelf slope. Interspersed between the coastal eddies are filaments and intense jets, often with dipole eddies at the...
The distribution of man-made and naturally produced halocarbons in a double layer flow strait system Fogelqvist, E; Tanhua, T; Basturk, O; Salihoglu, I (1996-08-01) The Bosphorus Strait, which connects the Black Sea and Mediterranean Sea via the Marmara Sea, is characterised by two distinct water masses. The upper layer consists of low density Black Sea water (sigma-t 10-11) flowing southward, and it is underlain by high density water (sigma-t > 28) of Mediterranean origin flowing northward. The sharp density gradient between the two layers is due to the difference in salinities. Here we report measurements on a suite of low molecular weight halocarbons together with b...
Historical and pre-historical tsunamis in the Mediterranean and its connected seas: Geological signatures, generation mechanisms and coastal impacts Papadopoulos, Gerassimos A.; Gracia, Eulalia; Urgeles, Roger; Sallares, Valenti; De Martini, Paolo Marco; Pantosti, Daniela; Gonzalez, Mauricio; Yalçıner, Ahmet Cevdet; Mascle, Jean; Sakellariou, Dimitris; Salamon, Amos; Tinti, Stefano; Karastathis, Vassilis; Fokaefs, Anna; Camerlenghi, Angelo; Novikova, Tatyana; Papageorgiou, Antonia (Elsevier BV, 2014-08-01) The origin of tsunamis in the Mediterranean region and its connected seas, including the Marmara Sea, the Black Sea and the SW Iberian Margin in the NE Atlantic Ocean, is reviewed within the geological and seismotectonic settings of the region. A variety of historical documentary sources combined with evidence from onshore and offshore geological signatures, geomorphological imprints, observations from selected coastal archeological sites, as well as instrumental records, eyewitnesses accounts and pictorial...
The experimental analysis on the Late Quaternary deposits of the Black Sea Tekiroglu, SE; Ediger, V; Yemenicioglu, S; Kapur, S; Akca, E (Elsevier BV, 2001-01-01) Holocene sediments taken from the south-eastern and western Black Sea have been investigated in relation to their geochemical, sedimentological and mineralogical characteristics. Their textures are characterized by their low amount of sand, upward-increasing silt and downward-increasing clay contents. While the terrigenous materials transported from Anatolian volcanic-based sources and European alluvial sediments form the shore deposits, the deep-sea sediments mainly consist of the marine biological product...
A baroclinic three dimensional numerical model applied to coastal Lagoons Balas, L; Ozhan, E (2003-01-01) An implicit barochnic unsteady three-dimensional model (HIDROTAM3) which consists of hydrodynamic, transport and turbulence model components, has been implemented to two real coastal water bodies namely, Oludeniz Lagoon located at the Mediterranean coast and Bodrum Bay located at the Aegean Sea coast of Turkey. M2 tide is the dominant tidal constituent for the coastal areas. The flow patterns in the coastal areas are mainly driven by the wind force. Model predictions are highly encouraging and provide favor...
