Suspended particulate organic matter (SPOM) both from the oligotrophic Mediterranean and from the more productive Black Sea has been analysed by pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS) and by such conventional techniques as elemental analysis and fluorometry. The data achieved by the two approaches generally confirmed and complemented each other. The relative concentrations of pyrolysis products (termed markers) characteristic of chlorophyll (CHL), lipid, carbohydrate (CBH), and protein (PROT) components of SPOM have been determined. The vertical distribution of lipid markers was more uniform in the Mediterranean surface waters. Their relative abundance increased rapidly in the oxycline of the Black Sea, reaching their highest levels in the suboxic zone, where the protein composition of the SPOM changed significantly. In both seas, the relative concentrations of CHL markers increased consistently within the CHL maximum zone where the CBH markers were less abundant. No lignin markers from terrestrial vegetation were detected at significant levels in the pyrograms.

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...
Comparison of Source Regions Affecting SO42- and NO3- Concentrations at the Eastern Mediterranean and Black Sea Atmospheres Dogan, G.; GÜLLÜ, GÜLEN; Karakas, D.; Tuncel, G. (Bentham Science Publishers Ltd., 2010-01-01) In this study, source regions of atmospheric sulfate and nitrate in rural areas at the Black Sea and the Mediterranean coasts of Turkey are compared. Stations on the Black Sea and Mediterranean Sea are located at Amasra and Antalya regions, respectively. Source regions of SO42- and NO3- are determined by using potential source contribution function (PSCF). Statistical significance of source regions assigned by PSCF were assured using bootstrapping with 3000 iterations. Source regions affecting sulfate and n...
Distribution of dissolved and particulate forms of iron and manganese in the Black Sea Erdoğan, Selahattin; Yemenicioğlu, Semal; Department of Marine Sciences (2002) The principal aim of this study is to examine the behavior of dissolved inorganic and particulate forms of manganese and iron compounds in the oxic/anoxic transition (suboxic) zone of the western cyclone and coastal margin of the Black Sea. The samples were collected from the stations visited during three cruises of RV/Bilim at July 2000, September 2000, July 2001 and RV/Knorr at July 2001 in the Black Sea. In addition, real time profiles of dissolved Mn and Fe(ll) were obtained using a continuous profiling...
Investigation of ash deposition in a pilot-scale fluidized bed combustor co-firing biomass with lignite Gogebakan, Zuhal; Gogebakan, Yusuf; Selçuk, Nevin; Seliuk, Ekrem (2009-01-01) This study presents the results from investigation of ash deposition characteristics of a high ash and sulfur content lignite co-fired with three types of biomass (olive residue, 49 wt%; hazelnut shell, 42 wt%; and cotton residue, 41 wt%) in 0.3 MWt Middle East Technical University (METU) Atmospheric Bubbling Fluidized Bed Combustion (ABFBC) Test Rig. Deposit samples were collected on all air-cooled probe at a temperature of 500 degrees C. Samples were analyzed by SEM/EDX and XRD methods. The results reveal...
Preparation and characterization of silver sers nanotags Kibar, Seda; Volkan, Mürvet; Department of Chemistry (2010) Tags are materials used for labeling substances and so make possible the qualitative and quantitative analysis both in macroscopic and microscopic world. Nowadays, surface enhanced Raman spectroscopy became the favored one among the optical based-tag detection systems. Progress in surface enhanced Raman detection and imaging technologies depends on the availability of Raman labels with strong light scattering characteristics. In this study various SERS nanotags were prepared. An ideal SERS nanotag consists ...
