The Magnificent City of KSA
 Modern Science has discovered that in the places where two  different seas meet, there is a barrier between them. This barrier divides the  two seas so that each sea has its own temperature, salinity, and  density.

For example, Mediterranean sea water is warm, saline and less  dense, compared to Atlantic ocean water. When Mediterranean sea water enters the  Atlantic over the Gibraltar sill, it moves several hundred kilometers into the  Atlantic at a depth of about 1,000 meters with its own warm, saline and less  dense characteristics. The Mediterranean water stabilizes at this depth  (Principles of Oceanography p. 93).
The Mediterranean sea water as it enters the Atlantic over the Gibraltar sill with its own warm, saline and less dense characteristics, because of the barrier that distinguishes between them. Temperatures are in degrees Celsius (C).

Even in depths (indicated here by darker colors) up to 1,400  meters and at distances ranging from a minus -100 to +2,500 meters, we find that  both bodies of water maintain their individual temperatures and  salinity.
Although there are large waves, strong currents, and tides in these seas, they do not mix or transgress this barrier.
