Artificial intelligence techniques of neural network and fuzzy systems were applied as alternative methods to determine beach litter grading, based on litter surveys of the Antalya coastline (the Turkish Riviera). Litter measurements were categorized and assessed by artificial intelligence techniques, which lead to a new litter categorization system. The constructed neural network satisfactorily predicted the grading of the Antalya beaches and litter categories based on the number of litter items in the general litter category. It has been concluded that, neural networks could be used for high-speed predictions of litter items and beach grading, when the characteristics of the main litter category was determined by field studies. This can save on field effort when fast and reliable estimations of litter categories are required for management or research studies of beaches-especially those concerned with health and safety, and it has economic implications. The main advantages in using fuzzy systems are that they consider linguistic adjectival definitions, e.g. many/few, etc. As a result, additional information inherent in linguistic comments/refinements and judgments made during field studies can be incorporated in grading systems.

A statistical riverine litter propagation model
Balas, CE; Williams, AT; Simmons, SL; Ergin, Ayşen (Elsevier BV, 2001-11-01)
A statistical riverine litter propagation (RLP) model based on importance sampling Monte Carlo (ISMC) simulation was developed in order to predict the frequency distribution of certain litter types in river reaches. The model was preliminarily calibrated for plastic sheeting by a pilot study conducted on the River Taff, Wales (UK). Litter movement was predominantly controlled by reach characteristics, such as vegetation overhang and watercourse obstructions. These affects were modeled in the simulations, by...
MED POL survey of organotins in the Mediterranean
Gabrielides, G.P; Alzieu, C; Readman, J.W; Bacci, E; Aboul Dahab, O; Salihoglu, I (Elsevier BV, 1990-5)
A pilot survey of tributyltin (TBT) and its derivatives in Mediterranean areas was undertaken in 1988 within the framework of the MED POL activities. The areas studied were the French Mediterranean coast, the Northern Tyrrhenian coast, the Southern coast of Turkey and the Alexandria (Egypt) coastal area. 113 water samples were analysed from the first three areas and 35 sediment samples from the fourth. Samples were collected at sites selected according to differing environmental conditions and potential inp...
Pelagic tar in the Mediterranean Sea
Weber, K.; Loizides, L.; Golik, AF; Salihoğlu, İlkay; Yılmaz, Ayşen (Elsevier BV, 1988-11)
Floating tar samples were collected, using neuston nets, in 101 stations in the Mediterranean Sea in August–September, 1987, by research vessels of Cyprus, Germany, Israel, and Turkey. The distribution of the tar content indicates that the most tar contaminated sea is in the northeast between Cyprus and Turkey and in the Gulf of Sirte off the coast of Libya, where the mean tar content was 1847 and 6859 μg m−2, respectively. The least polluted areas were the western Mediterranean, 236 μg m−2, and the norther...
Water level and fish-mediated cascading effects on the microbial community in eutrophic warm shallow lakes: a mesocosm experiment

Information on the effects of water level changes on microbial planktonic communities in lakes is limited but vital for understanding ecosystem dynamics in Mediterranean lakes subjected to major intra- and inter-annual variations in water level. We performed an in situ mesocosm experiment in an eutrophic Turkish lake at two different depths crossed with presence/absence of fish in order to explore the effects of water level variations and the role of top-down regulation at contrasting depths. Strong effects...
Assessment of temporal variation and sources of PCBs in the sediments of Mediterranean Sea, Mersin Bay, Turkey
Gedik, Kadir; İmamoğlu, İpek (Elsevier BV, 2011-01-01)
Information on temporal distribution of polychlorinated biphenyls (PCBs) in the coastal sediments of Mediterranean Sea, Mersin was compiled using data published between 1980 and 2009, and the present study. The first congener specific PCB results from the region yield concentration levels of Sigma(41) PCBs in sediments ranging from 0.61 to 1.04 ng g(-1). Sediment profiles show penta-, hexa- and hepta-chlorobiphenyls, specifically, #149 and 153 as the most abundant congeners in all samples. Comparison of tot...
