Definition of sensitive areas in a lakeshore by using remote sensing and GIS

In this study, the temporal changes of sensitive areas such as shorelines, wetlands, and rivers of Beysehir Lake were determined by means of 1(st) October 1987 and 4(th) July 2000 Landsat 5 TM satellite sensor data. Digital image processing techniques were conducted for the processes of image enhancement, manipulation, registration and classification for digital change analysis. Sensitive areas were digitized from both images. The obtained results were compared with each other, visualized and analyzed, using Geographic Information System (GIS). According to the results, it could be observed that the area of the lake is decreased by around 2%, that of wetlands increased by 38% between 1987 and 2000. Also the water above sea level has been decreased from 1123.05 in in 1987 to 1122.12 in in the year of 2000

Distribution of enteric bacteria by means of GIS and detection of Escherichia coli with uidA gene in Kapıdağ Peninsula of Marmara Sea

Present study consists the incidence of enteric bacteria in the Kapıdağ Peninsula. Nine sampling stations were selected and taken seasonally from 2011-2012. Presence of Escherichia coli was noted at all stations, except K1 and K6, throughout the sampling period irrespective of season. K1 and K6 stations (utilised as public beaches during the summer months) and depths below 30m displayed distinct genetic profile suggestive of diverse community of enteric bacteria other than E. coli. Analysis of uidA gene showed temporal and spatial genetic homogeneity in these E. coli populations. Ability to characterize E. coli communities might not only facilitate the mitigation of fecal pollution on Kapıdağ Peninsula, but also address the impact of environmental disturbances and seasonal and spatial variation on pathogen indicators
