**2.1.5 Aegean Sea**

The pelagic zones of the northern Aegean Sea and the Sea of Marmara share some main features due to their connection through the Çanakkale Strait. However, because of the anthropological sources, bacterial pollution level of northern part of the Aegean Sea less than the Sea of Marmara (Altuğ et. al., 2007). The population rate rises during the summer season due to recreational activities, compared with the other months in the coastal areas of the Aegean Sea. This situation is inducing the level of bacterial pollution (Altuğ et. all., 2007)
