Geochemistry of Regional Groundwater Flow in the Aladag Karstic Aquifer, Eastern Taurids-Turkey: Effect of Flow Conditions, 1995, Bayari C. Serdar, Kurttas Turker
The geochemistry of regional groundwater flow along the Aladag karstic aquifer indicates a remarkable correlation between the hydraulic and geochemical conditions. The Aladag. karstic aquifer, in between the recharge area and the regional erosion base, comprises unconfined and confined sections. A transition zone along which semi-confined flow conditions dominate also occurs between these sections. The parts of the aquifer in which unconfined and confined flow conditions dominate seem to be analogous of geochemically open and closed systems of carbonate dissolution, respectively. The varition of physical and chemical properties of the karstic effluents implies that although the carbonate dissolution is perpetual along the flow system, dissolution rates decrease where confined flow conditions start to prevail. However, gypsum dissolution along the regional flow path seems to be independent of hydraulic conditions.

Combined use of environmental isotopic and hydrochemical data in differentiation of groundwater flow patterns through the Aladağ karstic aquifer-Turkey, Application of Tracers in Arid zone Hydro, 1995, Bayari C. S. , Gunay G.
Distinction between the different groundwater flow systems in karstic areas constitutes one of the major objetives of the basin-wide hydrogeologic research. Use of environmental isotopic and hydrochemical investigation techniques provide a great deal of information for the identification of regional groundwater flow systems. The Lower Zamantı Basin, located in the eastern Taurids, presents an accountable water resource potential that can be used for hydroelectric power production. The basin, with the elevation range between 400 m and 350 m, occupies a catchment area of 2000 km2. Humid and semi-arid climatic regimes prevail in the southern and northern parts of the basin. The carbonate rocks and the overlaying impervious ophiolite nappe constitute the major geologic units in the area. Systematic hydrochemical and environmental isotopic surveys have been carried out to discriminate between the different groundwater flow systems existing in the basin. Hydrochemical studies have been conducted by insitu measurements, sampling and analyses of water samples from about 80 points. Based on the results of hydrochemical evaluations, 23 sampling points, including streams and karstic springs, have been selected for environmental isotopic survey. The integrated evaluation of the available data indicates clearly that two different groundwater flow patterns exist in the basin; namely a shallow flow and a deep regional flow. The characteristic values of temperature, electrical conductivity, carbonate alkalinity and log PCO2 of the shallow-flow in the karstic effluents fed by shallow groundwater circulation springs are 8C, 80 S/cm, 1.5 meq/l and 10-2 atm, respectively. On the other hand, higher values, such as 15C, 455 S/cm, 5.0 meq/l and 10-1 atm are observed in the springs fed by deep-regional groundwater flow. The tritium data indicate that the springs fed by the deep-regional groundwater have longer residence times. Moreover, the recharge area elevations, as envisaged from the oxygen-18 data, also provide supporting evidence for the distinction of different groundwater flow patterns. Additionally, comparison of groundwater temperature with oxygen-18 content presents reliable information to understand the possible interaction among the different karstic effluents.

First record of Parastenocarididae (Crustacea, Copepoda, Harpacticoida) from subterranean freshwater of insular Greece and description of two new species., 1996, Bruno Maria Cristina, Cottarelli Vezio
The genus Parastenocaris, new for Greece, has been discovered in the hyporheic habitat of Kos and Kythira Island with two new species, that are described and discussed in this work. Parastenocaris aesculapii n. sp. shares some characters with P. nolli from Germany and P. italica from Italy, Macedonia and Turkey. Parastenocaris aphroditis n. sp. belongs, according to the Authors, to a group of species living exclusively in estuarine interstitial habitats, which are all characterised by peculiar morphology and ecology, that are as well considered and interpreted.

Petroleum geology of the Black Sea, 1996, Robinson A. G. , Rudat J. H. , Banks C. J. , Wiles R. L. F. ,
The Black Sea comprises two extensional basins formed in a back-arc setting above the northward subducting Tethys Ocean, close to the southern margin of Eurasia. The two basins coalesced late in their post-rift phases in the Pliocene, forming the present single depocentre. The Western Black Sea was initiated in the Aptian, when a part of the Moesian Platform (now the Western Pontides of Turkey) began to rift and move away to the south-east. The Eastern Black Sea probably formed by separation of the Mid-Black Sea High from the Shatsky Ridge during the Palaeocene to Eocene. Subsequent to rifting, the basins were the sites of mainly deep water deposition; only during the Late Miocene was there a major sea-level fall, leading to the development of a relatively shallow lake. Most of the margins of the Black Sea have been extensively modified by Late Eocene to recent compression associated with closure of the Tethys Ocean. Gas chromatography--mass spectrometry and carbon isotope analysis of petroleum and rock extracts suggest that most petroleum occurrences around the Black Sea can be explained by generation from an oil-prone source rock of most probably Late Eocene age (although a wider age range is possible in the basin centres). Burial history modelling and source kitchen mapping indicate that this unit is currently generating both oil and gas in the post-rift basin. A Palaeozoic source rock may have generated gas condensate in the Gulf of Odessa. In Bulgarian waters, the main plays are associated with the development of an Eocene foreland basin (Kamchia Trough) and in extensional structures related to Western Black Sea rifting. The latter continue into the Romanian shelf where there is also potential in rollover anticlines due to gravity sliding of Neogene sediments. In the Gulf of Odessa gas condensate has been discovered in several compressional anticlines and there is potential in older extensional structures. Small gas and oil discoveries around the Sea of Azov point to further potential offshore around the Central Azov High. In offshore Russia and Georgia there are large culminations on the Shatsky Ridge, but these are mainly in deep water and may have poor reservoirs. There are small compressional structures off the northern Turkish coast related to the Pontide deformation; these may include Eocene turbidite reservoirs. The extensional fault blocks of the Andrusov Ridge (Mid-Black Sea High) are seen as having the best potential for large hydrocarbon volumes, but in 2200 m of water

Hydrogeological study and discharge features of the Niksar karst springs (Tokat-Turkey), 1997, Syed M. A. , Afsin M. , Celik M. ,
The exposed Paleozoic and Recent units in the study area have various hydrogeological characteristics such as pervious, semipervious, and impervious. Pervious limestones and associated impervious formations that were not influenced by tectonic movement are connected to produce karst springs. This paper presents the relationship between the discharge coefficient and other aquifer properties by using the hydrograph analyses of the karst springs. The magnitude of the discharge of the spring apparently controls the character of flow (such as laminar) and conduit in the aquifer. The correlation analysis shows a positive relation between Q(0)-Q(t), Q(0)-storage capacity, Q(t)-storage capacity, and alpha-discharge change, These results enhances the properties of the karst springs. Both monthly and annual rainfall contribute to spring discharge. All karst springwaters are suitable for household and food industry uses

Role of public awareness in groundwater protection, 1997, Ekmekci M, Gunay G,
Scarcity of water, particularly in towns situated along the Mediterranean coast where the main aquifers are in karstic carbonate rocks, necessitates more thoroughness in exploiting and protecting the groundwater resources. Geomorphological and hydrogeological studies have revealed large quantities of the input and throughput features, such as sinkholes, dolines, uvalas and poljes in the recharge areas of many karst aquifers in Turkey. Naturally, recharge areas are generally located at higher elevations and regions remote from the urbanized areas. These features lead the local authorities and persons to utilize the karst features for their own purposes. Dolines and ponors are commonly utilized as injection points for wastewater, while uvalas and poljes are used as solid waste disposal sites. When doing this, the people are unconscious of the connection of such sites with the wells or springs that provide water for their supply. A number of occurrences in Turkey have demonstrated that, no matter how perfect the efficiency of the technical work, protection of the water resources-is primarily related to the consciousness of the local authorities. They must either take proper measures to protect the resources or to educate the public in this issue. To achieve this aim, it is very important to involve the public administrative sector and the technical sector in preparing guidelines for integrated environmental evaluation of karst water resources. The main phase of a study should include locating appropriate sites for disposal of wastewater and various liquid and solid wastes that will satisfy requirements by the administrators as well as providing a water supply of good quality for the public. This paper discusses the issue of how to overcome the public awareness problem. Some examples demonstrate how the technical, achievements failed to be effective and applicable due to the lack of contribution on the part of the local authorities and the public. Some suggestions are made concerning a revision of the currently insufficient regulations
