Abstract

Surface water taken from 12 different areas in the period from July 2002 to June 2003 from Sapanca Lake, (Sakarya, Turkey) was analyzed in order to detect levels of bacterial contamination, bacterial metabolic activity, and chemical content. Level of bacteria was examined with respect to Fecal coliform, Escherichia coli and Salmonella spp. The contribution of capsule-bearing bacteria to the total number of bacterioplankton community was enumerated in order to assume the metabolically active number of bacteria. Levels of dissolved oxygen, nitrate, nitrite, orthophosphate, total hardness and calcium were calculated. Bacterial counts were made using Membrane Filtration Technique. Capsulated and non-capsulated bacteria were determined using a modified negative staining technique. As a result, the highest level of F. coliform found was 24×10MPN/ 100 ml in the surface water samples, which were taken from the western side of the Lake. While Salmonella spp. was found to be positive, contribution of capsulated bacteria to the total bacteria was found to be higher (19.6 %) in the same region. Results of this study have shown that level of indicator bacteria and percentage of potentially active bacteria are higher in samples of surface water collected from western part of the Sapanca Lake. Evaluation of the relations between surface fecal coliform and other environmental factors showed that the western region of the Lake was exposed to sewage wastes.

Abstract

Marine algae and seagrasses were researched in the upper infralittoral zone of Adana (Turkish Mediterranean coasts) in this study. 381 algae and 5 seagrasses (Liliopsida) were determined (Total 386 taxa). 27 of them belong to blue-green algae (Cyanophyceae), 204 to red algae [Rhodellophyceae (2), Compsopogonophyceae (2), Bangiophyceae (5), Florideophyceae(195)], 78 to brown algae (Fucophyceae), 72 to green algae [Chlorophyceae (7), Ulvophyceae (18), Trentepohliophyceae (1), Cladophorophyceae (22) Bryopsidophyceae (22), Dasycladophyceae (2)]. Ceramium siliquosum (Kützing) Maggs & Hommersend var. zostericola f. zostericola, C. tenuicorne (Kützing) Waern (Rhodophyceae), Bryopsis adriatica (J. Agardh) Meneghini (Bryopsidophyceae) are given as newly record for the Mediterranean shores of Turkey.

Abstract

The aim of this study was to determine the ostracoda fauna of the South of Marmara Sea. The results were compared with the similar species from the surrounding seas. The Materials were obtained from 27 areas between 11 March-26 July 2000. 35 species were determined of which 12 were dominant. The findings showed that South of Marmara Sea generally contained cosmopolitan species, that were tolerant to salinity. Also total individual number of species in the South of Marmara Sea appeared to be positively correlated to dissolved oxygen (rs=0,409, p<0,05) rather than other ecological variables and temperature negatively correlated to dissolved oxygen (rs=-0,771, p<0,05).

Oil pollution in east part of Izmit Gulf

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.
