Istanbul, Turkey

January 19, 2006
This is a Landsat thematic mapper image of Istanbul, Turkey, in 2004.

The old part of the city, which corresponds to ancient Constantinople, lies on the south west corner of the Bosporus strait. The Bosporus, or Bosphorus, separates the European part of Turkey from its Asian part, connecting the Sea of Marmara with the Black Sea. It is 30 kilometers long, with a maximum width of 3,700 meters at the northern entrance, and a minimum width of 750 meters. The depth varies from 36 to 124 meters in midstream.

Two bridges cross the Bosporus Strait. The first, Bogazici (Bosporus I) bridge, is 1074 meters long and was completed in 1973. The second, Fatih Sultan Mehmed (Bosporus II) bridge, is 1090 meters long and was completed in 1988 about five kilometers north of the first bridge. Marmaray, a 13.7 kilometer-long rail tunnel is still under construction and is expected to be completed in 2008. Approximately 1,400 meters of the tunnel will run under the strait, at a depth of about 55 meters.
