Bosphorus




The Bosphorus or '''Bosporus''', also known as ''Istanbul Strait'', ( that forms the boundary between the Europe an part ( Rumeli ) of Turkey and its Asia n part ( Anadolu ). 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 ). It is approximately 30 km long, with a maximum width of 3,700 metres at the northern entrance, and a minimum width of 700 metres between Kandilli and Aşiyan; and 750 metres between Anadoluhisarı and Rumelihisarı. The depth varies from 36 to 124 metres in midstream.


The shores of the strait are heavily populated as the city of Istanbul (in excess of 11 million inhabitants) straddles it.

Two Bridge s cross the Istanbul Strait. The first, Bogazici (Bosphorus I) Bridge , is 1074 meters long and was completed in 1973 . The second, Fatih Sultan Mehmet (Bosphorus II) Bridge , is 1090 meters long, and was completed in 1988 about five kilometers north of the first bridge. A third road bridge is also being planned for one of seven locations designated by the Turkish Government. The location is being kept secret to avoid an early explosion in land prices.

Another crossing, Marmaray , is a 13.7 kilometer-long Rail Tunnel currently under construction and expected to be completed in 2008 . Approximately 1,400 metres of the tunnel will run under the strait, at a depth of about 55 meters.


ASSOCIATIONS

The name, means ''ox passage'' or ''cow-ford'' from the Greek word Bosphorus (Βόσπορος), it is associated with a Greek Myth about Io's travels after Zeus turned her into an Ox for her protection.

It is also said in myth that floating rocks once crushed any ship that attempted passage of the Bosporus until the hero Jason obtained passage by trickery, whereupon the rocks became fixed, and Greek access to the Black Sea was opened.


FORMATION OF THE BOSPHORUS

See Also: Black Sea deluge theory


While the exact cause for the formation of the Bosphorus remains the subject of vigorous debate among geologists, one recent theory (first published in 1997 by William Ryan and Walter Pitman from Columbia University ) contends that the Bosphorus was formed about 5600 BC when the rising waters of the Mediterranean/Sea of Marmara breached through to the Black Sea , which at the time (according to the theory) was a low-lying body of fresh water.

Some have argued that the resulting massive flooding of the inhabited and probably farmed northern shores of the Black Sea is the historic basis for the Flood Stories found in the '' Epic Of Gilgamesh '' and in the Bible in Genesis , Chapters 6-9.


ANCIENT GREECE, ROME, THE BYZATINES AND THE OTTOMAN EMPIRE

St. Jerome 's Vulgate translates the Hebrew ''besepharad'' in Obadiah, 1-20 as "Bosforus", but other translations give it as " Sepharad " (probably Sardis , but later identified with Spain).

As the narrowest point of passage between the Black Sea and the Mediterranean, the Bosphorus has always been of great commercial and strategic importance. The Greek city-state of Athens in the 5th Century BC , which was dependent on grain imports from Scythia , therefore maintained critical alliances with cities which controlled the straits, such as the Megarian colony Byzantium .

The strategic significance of the strait was one of the factors in the decision of the Roman Emperor Constantine the Great to found there in 330 AD his new capital, Constantinople , which came to be known as the capital of the Eastern Roman Empire . This city was later renamed Istanbul when, on May 29 1453 , it was conquered by Mehmed II of the Ottoman Turks and became the capital of the Ottoman Empire . In fact, as the Ottoman Turks closed in on Constantinople, they constructed a fortification on each side of the strait, Anadoluhisari ( 1393 ) and Rumelihisari ( 1451 ).


STRATEGIC IMPORTANCE TODAY

The strategic importance of the Bosphorus remains high, and control over it has been an objective of a number of hostilities in modern history, notably the Russo-Turkish War, 1877-1878 , as well as of the attack of the Allied Powers on the Dardanelles in 1915 in the course of the First World War . Several international treaties have governed vessels using the waters, including the Montreux Convention Regarding The Regime Of The Turkish Straits , signed in 1936 .
