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 and waiting for the final feasibility study, for which international funding would follow. The connection of the seas by canal was first suggested in the mid 19th century by British officers who were looking for ways to circumvent the French-built Suez Canal and had not realized that the level of the Dead Sea is much lower. Later on, at the end of the 19th century, planners thought how to use the Jordan River water for irrigation and to bring sea water to the Dead Sea to create energy from its position of -390 m below sea level. One of those
