The distribution of man-made and naturally produced halocarbons in a double layer flow strait system

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 basic hydrographic parameters in the strait.

In 7 different region which represent most used harbors, ports and fishing shelters in the Sea of Marmara and Black Sea in Turkey coasts. Ecological Quality Status was assesed by sampling soft -bottom macrozoobenthos from 22 stations in 2014.
Elemental composition of seston and nutrient dynamics in the Sea of Marmara
POLAT, ÇOLPAN; Tuğrul, Süleyman; ÇOBAN, YEŞİM; SALİHOĞLU, İLKAY (1997-01-01)
The Sea of Marmara, an intercontinental basin with shallow and narrow straits, connects the Black and Mediterranean Seas. Data obtained during 1991-1996 have permitted the determination of the elemental composition of seston in the euphotic zone and the N:P ratio of the subhalocline waters of the Marmara Sea. Since primary production is always limited to the less saline upper layer (15-20 m), of the Marmara Sea, the subhalocline waters of Mediteranean origin are always rich in nutrients (NO3 + NO2 = 8-10 mu...
Vertical distribution of marine cyanobacteria Synechococcus spp. in the Black, Marmara, Aegean, and eastern Mediterranean seas
Uysal, Zahit (2006-01-01)
The vertical distributions of the unicellular cyanobacteria Synechococcus were studied in several highly contrasting seas: the Black Sea, Sea of Marmara, Aegean Sea, and Mediterranean Sea. Cell abundances varied significantly on both vertical and horizontal scales in all physically and spatially discrete water masses. Epifluorescence microscope cell counts from all seas clearly showed that majority of the population remains suspended in the surface-mixed layer and decreases gradually towards the base of the...
Dynamics of High Energy Environment: Processes at the Turkish Strait System (DEEP)
Sannıno, Gianmaria; Sözer, Adil; Delfantı, Roberta; Tuğrul, Süleyman; Özsoy, Emin(2015)
The Turkish Straits System (TSS) controls the exchange between the Black Sea and the Mediterranean Sea. A sound understanding of the circulation and transport mechanisms of this complex system depends on a series of experimental investigations and modelling development that have been carried out. We focus on the characterization of the exchange through the TSS, the influence on the adjacent seas and in particular, the ventilation of the Black Sea by the effluent of Mediterranean water exiting the TSS. Exper...

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...
