Sea of Marmara about 22 parts per thousand, which is slightly greater than that of the Black Sea, but only about two-thirds that of most oceans. The water is much more saline at the sea bottom, averaging salinities of around 38 parts per thousand, similar to that of the Mediterranean Sea. This high-density saline water, like that of the Black Sea, does not migrate to the surface. Water from the Susurluk, Biga (Granicus) and Gonen Rivers also reduces the salinity of the sea, though with less influence than on the Black Sea. With little land in Thrace draining southward, almost all of these
Red Sea–Dead Sea Water Conveyance number of international donors. The water level in the Dead Sea is shrinking at a rate of more than one metre per year, and its surface area has shrunk by about 30% in the last 20 years. This is largely due to the diversion of over 90% of the water of the Jordan River. In the early 1960s, the river moved 1,500 million cubic metres of water every year from the Sea of Galilee to the Dead Sea. Dams, canals, and pumping stations built by Israel, Jordan and Syria now divert water for crops and drinking, and have reduced the
