Red Sea
Map showing the Red Sea and the countries surrounding it. The Red Sea is one of the most heavily traveled waterways in the world. It is about 1,200 miles (1,930 km) long, and its maximum width is about 190 miles (305 km).
It is estimated that the water in the Red Sea is completely renewed approximately every 20 years. This circulation is maintained by an inflow of water from the Gulf of Aden through the Bab el-Mandeb Strait, which compensates for the significant loss of water due to evaporation.1
