Abstract

In this work the influence of oil amount in sediment was determined using various reference oils by UVF. 15 reference oils which were transported from the Black Sea used for plotting of standard curve. The differences of oil amount found through reference oil equations were varied in sediment as 17.0-28.1 % in wet weight, 13.4-14.1 % in oven, 12.2-26.2 in freeze dryer. These results showed that reference oils have an important role on the amount of oil in sediment. In the determination of oil pollution, the pollutant oil must be used in the analysis as references for each time.

Abstract

Beachrocks were determined along the northern coasts of Cyprus Island. Their petrographic composition and nature of cementation were studied based mainly on detailed field descriptions, thin section interpretations and ICP-AES analyses. The present findings show that beachrocks take place preferentially on beaches backed by coastal sand dunes and marine terraces, but exceptionally on tectonically uplifted wave-cut platforms. Beachrocks show an enrichment of sand and gravel derived from Troodos massive and Girne range. Commonly, cementation has been likely occurred in the salt water-fresh water mixing zone.

Abstract

In this paper was investigated the influence of drying technique on oil amount in sediments. Drying techniques used for sediments were oven at 60°C or freeze dryer. For the comparison of the results wet and dried of sediments the highest oil pollution level was found in freeze drying technique. The comparison of the oil amount found in freeze drying sediment are 20 time fold wet weight method and two time fold oven method. The best results were obtained for freeze dryer method in tested techniques. Instead of the results showed that a seriouse lack exist for the determination of oil concentration in sediment.

Keywords: Sediment, wet/dried weight, oil determination

Abstract

This paper presents land use features and coastline changes on the Kepez Delta between 1962 and 2005 by using remote sensing, aerial photograph interpretations and field observations. Rapid increase of population of the Kepez town from 1935 to 2000 fits with a growth of 24 times, resulting in continual expansion (~23 times) of residential areas on fertile farming lands. The sprawling of summer houses in the Dardanos area to the south threatens agricultural lands and the coastal ecosystem on a large scale. Coastline changes occurred as result of natural morpho-dynamic processes and human involvement in the past 43 years. These changes are characterized by seaward progradation (sediment accumulation) of about 40 m and coastal retrogradation (marine erosion) of 20 m at various parts of the coastline.

Abstract

Delimitation and proclamations of the Exclusive Economic Zone in the Eastern Mediterranean Sea is important issue for several reasons for the bordering nations. The Mediterranean Sea is unique case due to geographical characteristics and some conflicts already existed on maritime delimitations among some nations. It’s a matter of fact that; all States will have to reach agreement, regarding proclamations of the delimitation of the Exclusive Economic Zone in the Eastern Mediterranean Sea. Equitable and reasonable principals and solutions are needed for the delimitation of maritime areas. Turkey has 1577 km long coastline in the Mediterranean Sea starting from Fethiye to Samandag border up to Syria. 1851 fishing boats fishing in the territorial waters and high sea areas. Turkey could not accepted de facto EEZ proclamations due to damage vital economical interests in the eastern Mediterranean Sea as limiting fishing rights in the high seas. Besides, the mineral and oil resources in the high seas are also substantial matter. Turkey already has conduct a scientific programme protection of the eastern Mediterranean in term of prevention of the marine pollution, invasive species, monitoring of the impacts of the climate change to the marine biodiversity, cetaceans protection, establishing high sea marine protected areas, IIU fisheries and others. International cooperation, compromise, consensus and concerted action are needed for the sustainable exploitation of the living resources and protection of the vulnerable Mediterranean environment. Probable Turkish EEZ borders in Eastern Mediterranean region are presented on a map.
