Elemental and ionic composition of the eastern Mediterranean precipitation was determined on the Mediterranean coast of Turkey between January 1992 and January 1994. Measured concentrations were comparable with the concentrations reported from other rural stations. Concentrations of elements and ions show strong short-term and well-defined long-term variations. Short-term variations are due to transport from different source areas whereas longterm (seasonal) variations are governed by the seasonal changes in the wet removal of particles during their transport from source areas to the eastern Mediterranean region. The most important characteristic of the precipitation in the eastern Mediterranean region is the extensive neutralization of acidity by the airborne CaCO3 particles from soil. Wet deposition fluxes of elements and ions are smaller than the fluxes reported from other rural stations owing to small annual rainfall in the region. Except for soil-related elements, wet deposition fluxes of all elements are significantly higher in the winter season. Annual wet deposition fluxes are highly episodic, with only 10-20 of the samples accounting more than 50% of annual fluxes for most of the measured elements and ions.

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...
Seasonal Changes in the Composition and Abundance ofZooplankton in the Seas of the Mediterranean Basin Kovalev, Av; Mazzocchı, Mg; Toklu Alıçlı, Benin; Skryabın, Va; Kıdeyş, Ahmet Erkan (2003-01-01) Seasonal changes in the composition, abundance and biomass of zooplankton in the seas of the Mediterranean basin (the Mediterranean, Black and Azov seas) have been reviewed using our own data and data from the literature. In the deep-water central regions of the seas, the seasonal cycle of zooplankton abundance is characterised by one maximum occurring in spring or summer. In the coastal regions, two to three peaks (spring, summer and autumn) exist for the zooplankton abundance. The amplitude of seasonal fl...
Chemical composition of Eastern Mediterranean aerosol and precipitation: Indications of long-range transport Almomani, Idrees; GÜLLÜ, GÜLEN; Ölmez, İlhan; ELER, ÜNAL; Ortel, E; Şirin, Gürol; Tuncel, Süleyman Gürdal (1997-01-01) Daily aerosol and wet-only precipitation samples were collected, between January 1992 and January 1994 at a permanent station established on the Mediterranean coast of Turkey. Collected aerosol and rain samples were analyzed for major ions and a host of trace elements using a combination of analytical techniques, including ion chromatography, atomic absorbtion spectrometry and instrumental neutron activation analysis. The results have demonstrated;hat concentrations of parameters studied are higher than cor...
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...
Seasonal variations of abundance and live/dead compositions of copepods in Mersin Bay, northeastern Levantine Sea (eastern Mediterranean) BEŞİKTEPE, ŞENGÜL; Tang, Kam Wing; Mantha, Gopikrishna (2015-01-01) The seasonality of abundance and live/dead compositions of copepods was studied in the northeastern Mediterranean Sea. Zooplankton, chlorophyll-a, and PO4 sampling was performed on a monthly basis from March 2006 to February 2007 at both a coastal station and an open water station. At the coastal station, high phytoplankton biomass was driven by PO4 input from the Lamas River. On annual average, copepod abundance was 53,075 and 140,227 ind. m(-2) at the coastal and open water stations, respectively. The mos...
