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 total PCB concentrations over time suggests no recent PCB input to the region. Using congener specific PCB data for the region, identity and contribution of PCB sources were also predicted using a chemical mass balance -based (CMB) receptor model. The CMB model identified Aroclor 1260 to be the major PCB source in coastal sediments. The potential sources for the PCBs were briefly discussed in terms of their use in various industrial applications.

Simulations of the Black Sea pelagic ecosystem by 1-D, vertically resolved, physical-biochemical models
Oguz, T; Ducklow, HW; Malanotte-Rizzoli, P; Murray, JW (Wiley, 1998-09-01)
The present paper summarizes the results of several simulations of the central Black Sea pelagic food web using three different 1-D, physical-biochemical, water column process models. The most simplified, five-compartment version is used to explore the robust biological features of the ecosystem and the role of upper-layer physics on the evolution of the euphotic zone biological processes. The other models, introducing additional biological complexities, show how these biologically structured models become ...
Parameterization of iron and manganese cycling in the Black Sea suboxic and anoxic environment
Konovalov, S; Samodurov, A; Oguz, T; Ivanov, L (Elsevier BV, 2004-12-01)
New and published data on the distribution and speciation of manganese and iron in seawater are analyzed to identify and parameterize major biogeochemical processes of their cycling within the suboxic (similar to15.6less than or equal tosigma(t)less than or equal tosimilar to16.2) and anoxic layers (sigma(t)less than or equal tosimilar to16.2) of the Black Sea. A steady-state transport-reaction model is applied to reveal layering and parameterize kinetics of redox and dissolution/precipitation processes. Pr...
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...
Modelling phytoplankton succession on the Bering Sea shelf: role of climate influences and trophic interactions in generating Emiliania huxleyi blooms 1997-2000
Merico, A; Tyrrell, T; Lessard, EJ; Oguz, T; Stabeno, PJ; Zeeman, SI; Whitledge, TE (Elsevier BV, 2004-12-01)
Several years of continuous physical and biological anomalies have been affecting the Bering Sea shelf ecosystem starting from 1997. Such anomalies reached their peak in a striking visual phenomenon: the first appearance in the area of bright waters caused by massive blooms of the coccolithophore Emiliania huxleyi (E huxleyi). This study is intended to provide an insight into the mechanisms of phytoplankton succession in the south-eastern part of the shelf during such years and addresses the causes of E. hu...
Identification of the oxic anoxic interface by isopycnal surfaces in the black sea
SAYDAM, AHMET CEMAL; Tuğrul, Süleyman; BAŞTÜRK, ÖZDEN; Oğuz, Temel (Elsevier BV, 1993-07-01)
The analysis of hydrochemical data collected in the Black Sea since 1987 shows that the upper boundary of the oxic/anoxic interface zone coincides with the nitrate maximum at the depths of sigma(t) congruent-to 15.40 +/- 0.10 isopycnal surface. Its lower boundary corresponds to the phosphate maximum depth at sigma(t) congruent-to 16.20 +/- 0.05 isopycnal surface, independent of the geographical location and season. In the absence of the continuous pump cast measurement system, and when the oxygen and sulphi...
