Black Sea has been subjected to various investigations from the 19th century to the present time, due to its unique oceanographic features and geological evolution. It has a surface area of 423 000 km2 (excluding the Azov Sea) and a volume of 547 000 km3. The Black Sea (BS) is an intercontinental and is almost a miniature ocean with its geological structure. Unlike other seas of the world, the BS shows unique quality and trophic properties. Fortunately, only the upper layer water of the BS is introduced into the Strait of Istanbul (SOI; Bosphorus) and has a significant effect on the quality and trophic conditions of the Marmara Sea (MS). These effects are discussed in the light of data obtained from collaborative efforts of processed satellite images and various research institutions.
