Came across this video on youtube ,Scientist have discovered places where two different seas meet, there is a fence between them, this blockade separates the two seas so that each sea has its own temperature, salinity, and mass and its called halocline, little did they know god mentioned it in the quran so so so long ago {(18) مَرَجَ الْبَحْرَيْنِ يَلْتَقِيَانِ (19) بَيْنَهُمَا بَرْزَخٌ لَا يَبْغِيَان} Sub7an allah :D
