The seasonal distribution of Leonnales persicus was studied along depth transects (10-200 m) of three stations located in the Levant Sea during February-November 2000. Leonnates persicus particularly dominated the slightly gravelly sand bottom of stations between 10 and 150 m. Its distributional pattern showed a seasonal trend: it inhabited depths between 40 and 150 m in February and May when surface temperature was below 21degreesC, whereas it preferred shallower waters (10-60 m) during the warm season (>29degreesC in August). The density of the species in the area varied between 10 and 130 ind m(-2), with a maximum at 25-30 m off Erdemli in August.


Density currents in the two-layer flow: an example of Dardanelles outflow
Besiktepe, ST (Elsevier BV, 2003-06-01)
Observations from hydrographic surveys are used to describe the density current flowing through the Dardanelles strait into the Marmara Sea. Aegean water plunges below the surface and flows into the Marmara Sea. This flow joins into the Marmara Sea as a negatively buoyant plume and sinks through the deeper parts. Seasonal variation in the incoming water density results in the observing mainly two different forms of the density current in this area. These two forms are boundary currents and intrusion. Bounda...
Satellite-detected early summer coccolithophore blooms and their interannual variability in the Black Sea
Cokacar, T; Oguz, T; Kubilay, N (Elsevier BV, 2004-08-01)
Interannual variability of the prevalent early summer coccolithophore blooms within surface waters of the Black Sea was studied by means of satellite-based bio-optical observations. Two coccolith detection algorithms, tested for the Black Sea conditions, were found to provide comparable spatial coccolith patterns consistent with the corresponding true color images. Reliability of the algorithms is also supported by several sets of time-series measurements in different parts of the basin. An analysis of 6 ye...
Assessment of temporal variation and sources of PCBs in the sediments of Mediterranean Sea, Mersin Bay, Turkey
Gedik, Kadir; İmamoğlu, İpek (Elsevier BV, 2011-01-01)
Information on temporal distribution of polychlorinated biphenyls (PCBs) in the coastal sediments of Mediterranean Sea, Mersin was compiled using data published between 1980 and 2009, and the present study. The first congener specific PCB results from the region yield concentration levels of Sigma(41) PCBs in sediments ranging from 0.61 to 1.04 ng g(-1). Sediment profiles show penta-, hexa- and hepta-chlorobiphenyls, specifically, #149 and 153 as the most abundant congeners in all samples. Comparison of tot...
Lateral injection of oxygen with the Bosporus plume - fingers of oxidizing potential in the Black Sea
Konovalov, SK; Luther, GW; Friederich, GE; Nuzzio, DB; Tebo, BM; Murray, JW; Oguz, T; Glazer, B; Trouwborst, RE; Clement, B; Murray, KJ; Romanov, AS (Wiley, 2003-11-01)
Saline and warm Mediterranean water flowing through the Bosporus Strait maintains a permanent pycnocline with vertical separation of oxic (O(2)), suboxic (absence of O(2) and H(2)S), and anoxic (H(2)S) zones in the Black Sea. The stable suboxic zone implies restricted vertical mixing of the upper oxic and lower anoxic layers and limited vertical flux of oxygen that cannot balance the upward flux of sulfide. We report data that directly confirm massive lateral injections (>200 km from the Bosporus) of oxygen...

A brief review of the meteorological setting, hydrography and the circulation in the Levantine Basin of the Eastern Mediterranean is given. The recent high resolution data obtained in POEM coordinated experiments of 1985–1986 are then used to optimally estimate the circulation in the basin in two different seasons and to describe the water mass distributions. Some of the features observed during the experiments support the historical knowledge on the locations of sub-basin scale gyres and the general circul...
