Limit Two Ocean - Quran Scientific Miracles

Modern science has revealed that in the places where two different seas meet any boundary between them.  This boundary divides the two seas so that each sea has a temperature, salinity and density of its own.. For example, Mediterranean sea has warm water, high salinity and more concentrated than the Atlantic ocean.. When the Mediterranean Sea through the strait of Gibraltar into the Atlantic, the water is moving several hundred miles to the Atlantic coast at a depth of 1000 meters while maintaining its warm, high salinity and more dense.. At this depth, the Mediterranean sea water is in stable condition.Although there are large waves, currents and strong tides, as if there is a limit that prevents mixing of water from the ocean these two (see figure 13).
 
The Qur'an mentions that there are boundaries between two seas that meet and they do not exceed this limit.  
 Allah berfirman: Allah says:
 

مَرَجَ الْبَحْرَيْنِ يَلْتَقِيَانِ بَيْنَهُمَا بَرْزَخٌ لَا يَبْغِيَانِ مرج البحرين يلتقيان بينهما برزخ لا يبغيان

 

He let the two seas to flow through both later met, among them there are limits are not exceeded respectively.  (The Qur'an, Ar-Rahman (55) :19-20)

Such new information on the human mind in the last century through the sophisticated equipment to measure temperature, salinity, density, solubility of oxygen and so on. The human eye can not see the difference between the two seas meet.. They look the same.
