Abstract

The oil pollution was carried out at 8 stations in eastern part of the Izmit Gulf. Oil contamination was determined by using the Iranian crude oil, imported mostly by TÜPRAS, Izmit Refinery, as the reference material. Oil levels found in this area varied in 2002 as 4.81-144.37 (µg/L), in 2003 1.52-9011.3(µg/L). When these findings are compared with the earlier results of 1994-1995 periods, and after the Gölcük – Izmit earthquake of 17 August 1999, the conclusion so reached has indicated that the rate of pollution decreased during the years. Outcomes for the Naval Zone Gölcük has been more promising and revealed that the rate of pollution sharply decreased as compared with the 1994-1995 results.

Abstract

In this study, in respect of “The Black Sea Pollution Monitoring Project”, the distribution of the qualitatively phytoplankton in the samplings during the periods of September 2004, April 2005 and October 2005 along the Turkish coasts of the Black Sea has been investigated and also has been presented a species list. The acquired list of the species will contribute so much to the phytoplankton control list of Turkish Coasts of the Black Sea. A total of 129 taxa belonging to 7 classes were identified in qualitative and quantitative samples. Diatoms represented the majority of the community (52.7 %), followed by dinoflagellates (36.4 %). Especially in the water samples of river inputs belonging to 4 classes were determined totally 12 fresh water algae species.

Abstract

In this research, marine algae and seagrasses were investigated in the upper infralittoral zone of Hatay (Turkish Mediterranean coasts). A total of 377 algae and 5 seagrasses were determined. 30 of them belong to blue-green algae (Cyanophyceae), 201 to red algae [Rhodellophyceae (2), Compsopogonophyceae (2), Bangiophyceae (5), Florideophyceae (192)], 73 to brown algae (Fucophyceae), 73 to green algae [Chlorophyceae (5), Ulvophyceae (19), Trentepohliophyceae (1), Cladophorophyceae (24), Bryopsidophyceae (22), Dasycladophyceae (2)] and 5 to seagrasses (Liliopsida).

TWO NEW FISH RECORDS FROM TURKISH COAST OF THE EASTERN MEDITERRANEAN: THE GARFISH, BELONE SVETOVIDOVICOLLETTE AND PARIN, 1970; THE SPINY GURNARD, LEPIDOTRIGLA DIEUZEIDEI AUDOIN IN BLANC AND HUREAU, 1973.

Two new fish records from Turkish coast of the Eastern Mediterranean: The garfish, Belone svetovidovi Collette and Parin, 1970; the spiny gurnard, Lepidotrigla dieuzeidei Audoin in Blanc and Hureau, 1973.

Abstract

One specimen of Belone svetovidovi (SL: 326 mm, TL: 349 mm) was captured by net off Samandağı (Hatay) on 29 April 2004. Lepidotrigla dieuzeidei (SL: 102 mm, TL: 126 mm) was obtained by bottom trawl haul on 24 April 2004 at a depth of 77 m in Iskenderun Bay. Thus, B. svetovidovi and L. dieuzeidei reported in this study is the first record for Turkish coast of the Eastern Mediterranean.

Abstract

Generalized data of biogenic properties investigations of the Black Sea deep waters from its reduction zone for marine algae are presented. It is shown on board and in laboratory that after pre-oxidation of hydrogen sulphide by intensive aeration of the deep waters lifted to the surface of the sea, they are ready to be used for cultivation of the Black Sea unicellular, planktonic, and multicellular, benthic, algae instead of artificial medium. Naturally balanced micro- and macroelements structure and enriched content of nutrients are characterized the Black Sea deep waters. As a matter of fact after full oxidation of hydrogen sulphide they become the high-quality nutrient medium comparable with and even exceeding of the best man-made cultural medium.

LITTORAL CONCENTRATION OF LIFE IN THE BLACK SEA AREA AND COASTAL MANAGEMENT REQUIREMENTS

Littoral concentration of life in the Black Sea area and coastal management requirements

Abstract

The biological diversity, numbers and biomass of plants and animals in the Black Sea coastal zone up to 5 m depth are at least twice as much than deeper. This phenomenon is due to presence of many permanent inhabitants and to adlittoral breeding and feeding migrations of fish. Predominance of early stages of development of marine organisms is very characteristic for this ecologic zone. Adjoining coastal wetlands are also very rich in marine, brackish water and salt water organisms. Different human activities in coastal zone are the reason of various ecological conflicts. Presented matrix of these conflicts in the Black Sea area can be useful for Integrated coastal zone management purposes.
