High-resolution modelling, for the first time, is used to study the basic hydrodynamics of the Turkish Straits System (TSS). Hydraulic controls in the Bosphorus and Dardanelles Straits are found to be essential in determining the coupled response of the TSS, which directly influences the interaction between the Mediterranean and Black Seas. The mixed baroclinic-barotropic response of the system is investigated as a function of the net barotropic flux and density stratification imposed at external boundaries, in the absence of atmospheric and tidal effects. The intense surface jet issuing from the Bosphorus is found to drive the basin-wide circulation of the Marmara Sea, varying with the net flux. The temporal response of the Bosphorus and Dardanelles Straits picks up rather fast, within a day or two, thanks to hydraulic controls within straits, while the surface currents in the Marmara Sea only approach steady state after a few months. Model stratification and circulation features are validated against independent measurements and a stand-alone model of the Bosphorus.

Phytoplankton Growth Rate and Zooplankton Grazing in the Western Part of the Black Sea in the Autumn Period Stel'makh, L. V.; Babich, II; Tuğrul, Süleyman; Moncheva, S; Stefanova, K (Pleiades Publishing Ltd, 2009-02-01) The results of the studies within the framework of the international expedition onboard R/V Vladimir Parshin in September - October 2005 are presented. Intensive development of Bacillariophyceae and Dynophyceae was recorded in the coastal waters of Bulgaria, Turkey, and in the Danube River Delta during the period of the investigations. The increase in the algae population was accompanied by rising of the Chlorophyll a concentration up to 2.0-5.5 mg m(-3). In the deep water region, it did not exceed 0.54 mg ...
A SYNTHESIS OF THE LEVANTINE BASIN CIRCULATION AND HYDROGRAPHY, 1985-1990 OZSOY, E; HECHT, A; UNLUATA, U; BRENNER, S; SUR, HI; BISHOP, J; LATIF, MA; ROZENTRAUB, Z; OGUZ, T (Elsevier BV, 1993-01-01) The Levantine Basin circulation derived from recent data consists of a series of sub-basin-scale to mesoscale eddies interconnected by jets. The basin-scale circulation is masked by eddy variability that modulates and modifies it on seasonal and interannual time scales. Long-term qualitative changes in the circulation are reflected in the bifurcation patterns of the mid-basin jets, relative strengths of eddies and the hydrographic properties at the core of these eddies. Confinement within the Basin geometry...
A 2-LAYER MODEL OF WATER EXCHANGE THROUGH THE DARDANELLES STRAIT OGUZ, T; SUR, HI (1989-01-01) Water exchange through the Dardanelles Strait is studied by a two-layer model which considers the laterally averaged flow formed by two homogeneous layers of differing density separated by an entraining interface. The model response is discussed in terms of observations from the strait. In particular, the observed asymmetry and rapid transition at the interface depth as weil as the intense mixing which occurs in the southwestern reaches of the strait are found to be related to the hydraulic characteristics ...
Measurement of electroweak production of two jets in association with a Z boson in proton-proton collisions at root s=8 TeV Khachatryan, V.; et. al. (Springer Science and Business Media LLC, 2015-02-01) The purely electroweak (EW) cross section for the production of two jets in association with a Z boson, in proton-proton collisions at root s = 8 TeV, is measured using data recorded by the CMS experiment at the CERN LHC, corresponding to an integrated luminosity of 19.7 fb(-1). The electroweak cross section for the lljj final state (with l = e or mu and j representing the quarks produced in the hard interaction) in the kinematic region defined by M-ll > 50 GeV, M-jj > 120 GeV, transverse momentum p(Tj) > 2...
Measurement of WZ and ZZ production in pp collisions at in final states with b-tagged jets Chatrchyan, S.; et. al. (Springer Science and Business Media LLC, 2014-08-01) Measurements are reported of the WZ and ZZ production cross sections in proton-proton collisions at in final states where one Z boson decays to b-tagged jets. The other gauge boson, either W or Z, is detected through its leptonic decay (either , or , , or ). The results are based on data corresponding to an integrated luminosity of 18.9 fb collected with the CMS detector at the Large Hadron Collider. The measured cross sections, and , are consistent with next-to-leading order quantum chromodynamics calculat...
