Abstract

In this work the oil and detergent pollutions were investigated in sea water, near the refinery of TUPRAŞ and Ali Ağa, Istanbul Strait, Golden Hom and Çanakkale Strait. The pollutions were higher in refinery areas. The results inadequate that there is apparently no regular seasonal variation in oil and detergent amount. The maximum oil concentration in sea water was found 29.55 µg/L for Istanbul Strait 4214.29 µg/L for Golden Hom and 42.96 µg/L for Çanakkale Strait in 19.02.2005 and 90.02 µg/L for TUPRAŞ 3, 71.77 µg/Lfor Ali Ağa 2, in 07.Agust. 2006., in sediment 9573.38 µg/g for Istanbul Strait, 1126.45 µg/g for Golden Horn, 31.52 µg/g for Çanakkale Strait in 21.02.2005, 1500.6 µg/g for TUPRAŞ in 13.11.2006, 58.64 µg/g for Ali Ağa in 7.12.2006. These oillevels found are higher than the limit values for sea water and sediment. The LAS levels found are similar in earIier findings of this area.

Abstract

This paper, the Oligochaeta fauna of some lakes located at the West Black Sea Region of Turkey, was reported using results obtained. Having no previous faunistic studies, some physico-chernical features and Oligochaeta fauna of the lakes were determined for the first time in this research. Consequently, 30 species were determined, 13 species from Tubificidae family and 17 species from Naididae family. The average density of total Oligochaetes in the benthos of the lakes was 417 individuals m-2. The dominant species Tubifex tubifex accounted for 170 individuals m-2 and represented 40.7 % of total Oligochaeta community in the lakes studied. With regard to the rational distribution of species by station, Station 9 (Lake Yeniçağa) was the richest with 19.75% and Station 7 (Lake Abant) was the poorest with 3.23%. There are no data on the Oligochaeta fauna of this region so far. The determined taxa from is region.

Abstract

The seasonal changes in the histological profile of the ovary of Mytilus galloprovincialis Lamarck, 1819 were examined at light microscopic level and the alterations in the amount of total protein in the ovary were revealed by biochemical analyses. Samples were monthly collected from designated areas in Yenikapi shores of Sea of Marmara between June 2004 – May 2005. Although reproductive activities of Mytilus galloprovincialis populations in these areas decreased in some months, it has been observed that the reproduction activity has continued all the year round. The annual temperature alterations that have been measured were not much effective on the reproductive cycle.

Abstract

In this study the materials collected from the Northern coasts of Sea of Marmara between 1999- 2000 were evaluated and 33 species from 16 genera has been determined. Among these species Callistocythere diffusaLoxoconcha littoralis and Loxoconcha pontica are new records for the Sea of Marmara. According to the Spermann analysis the primary hydrographical variables did not seem to be very effective in the distribution dynamics of the ostracod species in the Sea of Marmara. However according to the MDS analysis, it has been observed that Cyprideis torosa was affected by temperature, Xesteloberis communis by salinity, Loxoconcha rhomboidea and Paracytheridea parallia by dissolved oxygen when compared to other species.

Abstract

Two remarkable scientific events happened recently (Zaitsev, Polikarpov, Egorov et al., 2007, 2008) in the field of the newly developed deep-sea ecology and molismology of the hydrogen sulphide pelocontour in the Black Sea bathyal zone: discovery (in 2007) of viable spores of oxybionts in this aggressive zone against openly living oxybionts – those organisms which normally inhabit all three biocycles of the biosphere – the land, the fresh waters and the marine environment as well as Determination (in 2008) of the safe sojoum duration of the oxybionts’ spores by radioisotope dating in layers of the studied pelocontour sediment. Generalization and discussion of these events are presented.

THE ROLE OF REFERENCE CRUDE OILS USED IN THE DETERMINATION OF OIL AMOUNT IN SEDIMENTS BY UVF

The role of reference crude oils used in the determination of oil amount in sediments by UVF

Istanbul University, Institute of Marine Science and Management, Müşküle Sok. 1 Vefa, İstanbul, TURKEY

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.

Istanbul University, Institute of Marine Science and Management, Müşküle Sok. Vefa, İstanbul, TURKEY

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.
