~~~Where two water bodies meet... but do not mix!~~~

This photo was taken by a tourist  Kent Smith.

 In this photo two bodies of water were merging in the middle of The Gulf of Alaska and there was a foam developing only at their junction. It is a result of the melting glaciers being composed of fresh water and the ocean has a higher percentage of salt causing the two bodies of water to have different densities and therefore makes it more difficult to mix.

This is a living exmaple of the following verse in the Qur'an:

[Surah Al-Rahman 55:19] He has set flowing two seas that appear to meet.

[Surah Al-Rahman 55:20] Whereas there is a barrier between them so they cannot encroach upon one another.

[Surah Al-Rahman 55:21] So O men and jinns! Which favour of your Lord will you deny?

In All probability,this is a type of of halocline.In oceanography, a halocline is a subtype of chemocline caused by a strong, vertical salinity gradient within a body of water. Because salinity (in concert with temperature) affects the density of seawater, it can play a role in its vertical separation as can be seen in this photo.

As Allah says in another place in the Qur'an:

And He is the One Who joined two rivers, this (one) very sweet and freshening and that (other one) very salty and bitter. And He set a barrier and a strong partition between them.{Surah Al-Furqan Chapter 25 : Verse 53}

This phenomenon occurs in several places, including:

·  The divider between the Mediterranean and the Atlantic Ocean at Gibralter.

·  Cape Point, Cape Peninsula, South Africa where the Atlantic Ocean meets the Indian Ocean.

·   Egypt, where the river Nile flows into the Mediterranean Sea.

These scientific phenomena mentioned in the Qur’an was also confirmed by Dr. William Hay, a well known marine scientist and Professor of Geological Sciences at the University of Colorado, U.S.A.
