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
Ligurian Alps Ligurian Alps The Ligurian Alps are a mountain range in northwestern Italy. A small part is located in France. They form the south-western extremity of the Alps, separated from the Apennines by the Colle di Cadibona. The Col de Tende separates them from the Maritime Alps.
