The Bosphorus, also known as the Istanbul Strait, is a strait that forms part of the boundary between Europe and Asia. It—along with the Dardanelles—is one of two straits in Turkey. The world's narrowest strait used for international navigation, it connects the Black Sea with the Sea of Marmara (which is connected by the Dardanelles to the Aegean Sea, and thereby to the Mediterranean Sea),
The name comes from Greek Bosporos, which the ancient Greeks analysed as bous βοῦς 'ox' + poros πόρος 'means of passing a river, ford, ferry', thus meaning 'ox-ford', which is a reference to Io (mythology) from Greek mythology who was transformed into a cow and condemned to wander the earth until she crossed the Bosphorus where she met Prometheus.
The strait is between the limits 31 km long, with a width of 3,329 m at the northern entrance and 2,826 m (1.526 nmi) at the southern entrance. Its maximum width is 3,420 m (1.85 nmi) between Umuryeri and Büyükdere Limanı, and minimum width 700 m between Kandilli Point and Aşiyan. A 45-degree course alteration is required for the ships at this point. The current can reach 7–8 knots at this point.
The depth of Bosphorus varies from 36 to 124 m (118 to 407 ft) in midstream with an average of 65 m (213 ft). The deepest location is between Kandilli and Bebek with 110 m (360 ft). The most shallow locations are off Kadıköy İnciburnu on the northward route with 18 m (59 ft) and off Aşiyan Point on the southward route with 13 m (43 ft).
The shores of the strait are heavily populated as the city of Istanbul (with a metropolitan area in excess of 11 million inhabitants) straddles it.
