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 their termina. The extension of these features across the shelf-slope into the central basin offshore waters implies important dynamical processes related to the shelf-deep basin exchanges. These features are often steered by the topography and evolve continuously through the mixed baroclinic-barotropic instability of the Rim Current.

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...
Tsunamis in the Black Sea: Comparison of the historical, instrumental, and numerical data Yalçıner, Ahmet Cevdet; Talipova, T; Kurkin, A; Kozelkov, A; Zaitsev, A (American Geophysical Union (AGU), 2004-12-15) The tsunami hazard in the Black Sea is discussed by comparing historical, instrumental data and numerical results. There are 22 tsunami events in the Black Sea documented since the first century, and nine of them have occurred in twentieth century. The numerical simulations of tsunami propagation for the 1966 and 1939 events are performed by using the framework of the shallow-water theory. The instrumental data from tide gauge records are used to compare and validate the simulation results and estimate the ...
Modeling the response of top-down control exerted by gelatinous carnivores on the Black Sea pelagic food web Oguz, T; Ducklow, HW; Purcell, JE; Malanotte-Rizzoli, P (American Geophysical Union (AGU), 2001-03-15) Recent changes in structure and functioning of the interior Black Sea ecosystem are studied by a series of simulations using a one-dimensional, vertically resolved, coupled physical-biochemical model. The simulations are intended to provide a better understanding of how the pelagic food web structure responds to increasing grazing pressure by gelatinous carnivores (medusae Aurelia aurita and ctenophore Mnemiopsis leidyi) during the past 2 decades. The model is first shown to represent typical eutrophic ecos...
A hemispheric dust storm affecting the Atlantic and Mediterranean in April 1994: Analyses, modeling, ground-based measurements and satellite observations Ozsoy, E; Kubilay, N; Nickovic, S; Moulin, C (American Geophysical Union (AGU), 2001-08-27) One of the largest recorded dust tranpsort events originating from the great Sahara desert during April 1994 affected the entire region extending from the Caribbean to the Eurasian continent. This hemispherical transport of airborne dust took place during a series of storms that developed during the first three weeks of April in a background of low-index circulation. These repeated events are studied through the combined analyses and interpretation of atmospheric data, ground-based aerosol measurements, vis...
THE MODELING OF THE FLOW OF WATER THROUGH THE BOSPORUS JOHNS, B; OGUZ, T (1990-03-01) 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 b...
