The stable isotopes O-18 and H-2, together with the transient tracer H-3 can be used to identify origins and characteristics of distinct water masses in the Black Sea, and in its smaller neighbour, the Marmara Sea, connected between them and to the Mediterranean Sea through the Straits of Bosphorus and Dardanelles, respectively. Exchange through the system and the water mass formation and evolution are characterised, based on the isotope measurements. Spatial coverage including the shelf and deep regions, with improved accuracy and reduced noise provide-definitive assessments of pycnocline and deep mixing in the system.

Dating of the Black Sea Basin: new nannoplankton ages from its inverted margin in the Central Pontides (Turkey) Hippolyte, J. -C.; Mueller, C.; Kaymakcı, Nuretdin; SANĞU, ERCAN (Geological Society of London, 2010-01-01) The Eocene uplift and inversion of a part of the Black Sea margin in the Central Pontides, allows us to study the stratigraphic sequence of the Western Black Sea Basin (WBS). The revision of this sequence, with 164 nannoplankton ages, indicates that subsidence and rifting started in the Upper Barremian and accelerated during the Aptian. The rifting of the western Black Sea Basin lasted about 40 Ma (from late Barremian to Coniacian). In the inner, inverted, Black Sea margin, the syn-rift sequence ends up wit...
Modeling biogeochemical processes in subterranean estuaries: Effect of flow dynamics and redox conditions on submarine groundwater discharge of nutrients Spiteri, Claudette; Slomp, Caroline P.; Tuncay, Kağan; Meile, Christof (American Geophysical Union (AGU), 2008-02-22) [1] A two-dimensional density-dependent reactive transport model, which couples groundwater flow and biogeochemical reactions, is used to investigate the fate of nutrients (NO(3)(-), NH(4)(+), and PO(4)) in idealized subterranean estuaries representing four end-members of oxic/anoxic aquifer and seawater redox conditions. Results from the simplified model representations show that the prevalent flow characteristics and redox conditions in the freshwater-seawater mixing zone determine the extent of nutrient ...
Enrichment of metals in the surface sediments of Sapanca Lake Bakan, G; Balkas, TI (Wiley, 1999-01-01) A comprehensive lake sediment study was performed on the Sapanca Lake of Turkey in which certain metal analyses were conducted using inductively coupled plasma atomic emission spectroscopy. The purpose of the study was to find the enrichment of metals in the surface sediments of Sapanca Lake. A method, namely, the index of geoaccumulation, was used to define the degree of anthropogenic pollution in the Sapanca Lake basin. Results of the geoaccumulation index indicate that only enrichments of trace metals, c...
Understanding tsunamis, potential source regions and tsunami-prone mechanisms in the Eastern Mediterranean Yolsal, S.; Taymaz, Tuncay; Yalçıner, Ahmet Cevdet (Geological Society of London, 2007-01-01) Historical tsunamis and tsunami propagation are synthesized in the Eastern Mediterranean Sea region, with particular attention to the Hellenic and the Cyprus arcs and the Levantine basin, to obtain a better picture of the tsunamigenic zones. Historical data of tsunami manifestation in the region are analysed, and compared with current seismic activity and plate interactions. Numerical simulations of potential and historical tsunamis reported in the Cyprus and Hellenic arcs are performed as case studies in t...
Trace metal composition of suspended particulate matter in the water column of the Black Sea Yiğiterhan, O; Murray, J W; Tuğrul, Süleyman (Elsevier BV, 2011-09-20) We analyzed the chemical composition of suspended matter from the Black Sea for a complete suite of elements used as tracers for various sources and processes. Samples of suspended matter were collected at four stations from the Bosporus to the center of the western gyre during a R/V Bilim cruise in September 2000. Sample depths were from the oxic surface layer, the suboxic zone and the upper part of the anoxic (sulfidic) layer. All samples were analyzed for Al, Ti, V, Cr, Mn, Fe, Co, Cu, Zn, Mo, Ag, Cd, Ba...
