Major-ion geochemistry and mineralogy of the Salt Lake (Tuz Golu) basin, Turkey

In the Salt Lake basin of Turkey, chemical composition of inflow surface waters defines a continuous trend from Ca-HCO3-rich spring waters to Na-SO4-Cl-rich brines. Considerable compositional variation exists among the surface waters. Water-rock interaction governs compositional variations in springs, streams and rivers, and is enhanced by evaporation and precipitation of calcite and protodolomite. Solute concentrations of the streams and the rivers are partially controlled by the mineralogy of the playa deposits. The concentration increase from inflow surface waters to a Na-Cl-type lake surface brine is not accessible to direct observation. The principal cause of the evolution from SO4-rich brine to Cl-rich brine in the lake is interpreted as the recycling of solutes through the differential dissolution of efflorescent crusts.


Evaluation of Multiple Satellite-Based Precipitation Products over Complex Topography
DERIN, Yagmur; Yılmaz, Koray Kamil (American Meteorological Society, 2014-08-01)
This study evaluates the performance of four satellite-based precipitation (SBP) products over the western Black Sea region of Turkey, a region characterized by complex topography that exerts strong controls on the precipitation regime. The four SBP products include the Tropical Rainfall Measuring Mission (TRMM) Multisatellite Precipitation Analysis version 7 experimental near-real-time product (TMPA-7RT) and post-real-time research-quality product (TMPA-7A), the Climate Prediction Center morphing technique...
Superficial deep-water sediments of the Eastern Marmara Basin
Evans, G.; Erten, H.; Alavi, S. N.; Von Gunten, H. R.; Ergin, M. (Springer Science and Business Media LLC, 1989-3)
Superficial sediments (top ∼ Im) of the Eastern Mediterranean Basin, Sea of Marmara, Turkey accumulated rapidly (0.087 ± 0.012 g/cm2 · y) by hemipelagic sedimentation with only limited amounts of gravity flow or bottom current action under low oxygenated but not anoxic conditions. They have restricted faunas, relatively higher organic carbon (1–1.8%) and lower calcium carbonate (14–20%) contents than other Eastern Mediterranean Basin sediments. Sedimentation shows little change over the last millenium excep...
Observed basin-wide propagation of Mediterranean water in the Black Sea
Falina, Anastasia; Sarafanov, Artem; Özsoy, Emin; Turunçoğlu, Ufuk Utku (2017-04-01)
Mediterranean water entering the Black Sea through the Bosphorus Strait forms middepth intrusions that contribute to the salt, heat, and volume balances of the sea, ventilate its water column at intermediate depths and restrain the upward flux of hydrogen sulfide from deeper layers. Despite the importance for the Black Sea environment, the circulation of Mediterranean-origin water in the basin is fundamentally underexplored. Here we use hydrographic data collected from ships and Argo profiling floats to ide...
Evaluation of eutrophication control strategies for the Keban Dam reservoir
Soyupak, S; Mukhallalati, L; Yemisen, D; Bayar, A; Yurteri, C (1997-04-15)
The reservoir of the Keban Dam in eastern Anatolia is a very deep and large water body subject to significant seasonal water level fluctuations within a given hydrological year. At the present time, different sections of the reservoir have different trophic status and the upper portion of the reservoir, in particular, is eutrophic. In this regard, there is a need for the assessment of alternative strategies to be implemented for phosphorus and thus eutrophication control in this segment of the reservoir. In...
Polycyclic aromatic hydrocarbons (PAHs) in sea sediments of the Turkish Mediterranean coast, composition and sources
Tuncel, Süleyman Gürdal (2015-03-01)
The concentrations of polycyclic aromatic hydrocarbons (PAHs) were determined in 25 surface sediment samples from five sites located at Oludeniz Lagoon of the Turkish Mediterranean coast. The total concentration of the PAHs (1.85 +/- 1.39 mg/kg) was lower than the sediments from highly urbanized areas, while it was comparable with the sediments from similar locations. Acenaphthene and chrysene were dominant ones with the concentrations of 0.620 and 0.515 mg/kg, respectively. The isomeric ratios indicated th...
