We determined the composition of particles from several rivers entering the Black Sea as part of a broader study of the composition of suspended matter and sediments in the Black Sea. Suspended matter and surface sediment samples were collected from the Danube River draining from Europe and from four Turkish rivers (Sakarya, Yenice (Filyos), Kizilirmak and Yesilirmak Rivers) in Anatolia. All samples were digested and analyzed by inductively coupled plasma-mass spectrometry and atomic absorption spectrometry (flame and graphite furnace) instruments. The elements analyzed included Al, Ti, V, Cr, Mn, Fe, Co, Cu, Zn, Mo, Ag, Cd, Ba, Pb and U. The concentrations were compared as solid phase concentrations (ppm) and as Metal to Al (Me/Al) ratios. The compositions of the particulate matter data from Turkish rivers and surface sediment from the Danube River were very similar to each other and the average for the world's rivers. Both had slightly higher concentrations than global average crust. A suspended matter sample from the Danube River had elevated concentrations for some elements (Ag, Pb, Zn, Cd, Cu and Mn) that were probably due to anthropogenic contamination suggesting that some hot spots may exist in the Danube that need to be studied more thoroughly. We recommend that the best choice for subtracting the terrigenous component from Black Sea particulate and sediment samples is the average of the Turkish rivers suspended matter and Danube River sediment samples.

Trace metal composition of particulate matter in the water column and sediments of the Black Sea and regional rivers Yiğiterhan, Oğuz; Yemenicioğlu, Semal; Department of Chemical Oceanography (2005) The Black Sea, with its oxic, suboxic and anoxic layers, provides a unique environment for studying how biological and geochemical processes affect the composition of particulate matter. The elemental composition of particles in the Black Sea is controlled by their origin and sources. Particles from rivers are dominated by aluminosilicate material that has compositions similar to the earth̕s crust. In general this material is relatively unreactive. Biological processes in the upper oxic and suboxic layers o...
Basement structure and architecture of the Black Sea Basin Kaymakcı, Nuretdin; Horn, Brian (null; 2018-01-28) Black Sea consists of two separate back arc basins which opened at different times during the Cretaceous in response to northward subduction of the Neo-Tethys Ocean. The paucity of well data, complex geometries and seismic imaging challenges mean that questions remain regarding the basement architecture though most authors accept that, at least in part, both these basins are floored by oceanic crust, even though there are no magnetic stripes. Interpretation of deep, long offset seismic data (imaging to more...
Zooplankton of the Black Sea and the Eastern Mediterranean Similarities and dissimilarities Kovalev, Av; Mazzocchı, Mg; Sıokoufrangou, I.; Kıdeyş, Ahmet Erkan (2001-01-01) A synthesis of data on abundance and biomass of zooplankton in the Eastern Mediterranean (EMED) and the Black Sea shows major differences in the composition and structure of pelagic communities in the two basins. Few Mediterranean planktonic animals have invaded in the Black Sea. The great bulk of Black Sea species is represented by coastal inhabitants that spread throughout the whole basin. This process has been called “neritization” of the Black Sea fauna. Peculiarities in zooplankton assemblages of the B...
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...
Dry atmospheric fluxes of trace metals (Al, Fe, Mn, Pb, Cd, Zn, Cu) over the Levantine Basin: A refined assessment Koçak, Mustafa; Herut, B; Nimmo, M (2005-12-01) The current work presents dry deposition fluxes of trace metals to the Southern and Northern Levantine Basin of the Eastern Mediterranean Sea. The dry depositional inputs were calculated taking into account (i) the spatial gradients in metal aerosol concentrations across the Levantine Basin (using concentrations from two location, Erdemli, Turkey and Tel Shikmona, Israel over a 3 year sampling period), (ii) the air mass origins, (iii) air mass temporal influence across the north and south Levantine basins a...
