The waters of the two seas do not mix. Can you see the edge of the sea? Mediterranean Sea and Aegean Sea
Miracle of the Qur'an: Seas that don't mix
Sura 55 "The Merciful":
19. He confused two seas that meet each other.
20. Between them there is a barrier that they cannot cross.
Sura 25 "Discrimination":
53. He is the One who mixed two seas (kinds of water): one is pleasant, fresh, and the other is salty, bitter. He placed between them a barrier and an insurmountable obstacle.
Exploring the expanses of water in the Strait of Gibraltar, Jacques Yves Cousteau discovered an amazing fact that cannot be explained by science: the existence of two water bodies that do not mix with each other. They seem to be separated by a film and have a clear boundary between them. Each of them has its own temperature, its salt composition, flora and fauna. These are the waters of the Mediterranean Sea and the Atlantic Ocean in contact with each other in the Strait of Gibraltar.
“In 1962,” says Jacques Cousteau, “German scientists discovered that in the Bab el-Mandeb Strait, where the waters of the Gulf of Aden and the Red Sea converge, the waters of the Red Sea and the Indian Ocean do not mix. Following the example of our colleagues, we began to find out whether the waters of the Atlantic Ocean and the Mediterranean Sea mix. We first explored the waters of the Mediterranean - its natural salinity, density and life forms. We did the same in the Atlantic Ocean. These two masses of water have been meeting in the Strait of Gibraltar for thousands of years, and it would be logical to assume that these two huge water masses should have been mixed long ago - their salinity and density should have become the same, or at least similar. But even in places where they converge closest, each of them retains its properties. In other words, at the confluence of two masses of water, the water curtain did not allow them to mix.”
Upon discovering this obvious and incredible fact, the scientist was extremely surprised. “I rested on my laurels for a long time at this amazing phenomenon, which cannot be explained by the laws of physics and chemistry,” writes Cousteau.
But the scientist experienced even greater surprise and admiration when he found out that this was written in the Koran 1400 years ago. He learned about it from Dr. Maurice Boukay, a Frenchman who converted to Islam.
“When I told him about my discovery, he told me skeptically that this was said in the Koran 1400 years ago. It was like a bolt from the blue for me. And indeed, it turned out that way when I looked at the translations of the Koran. Then I exclaimed: “I swear that this Koran, from which modern science lags behind by 1400 years, cannot be the speech of a person. This is the true speech of the Most High.” After that, I accepted Islam and every day I was amazed at the truth, justice, ease, usefulness of this religion. I am infinitely grateful that He opened His eyes to the Truth,” Cousteau writes further.
September 29 - World Maritime Day - one of the international holidays in the United Nations system. This day has been celebrated since 1978 by decision of the 10th session of the Assembly of the Intergovernmental Maritime Consultative Organization (International Maritime Organization).
The seas and oceans carry many secrets that have yet to be discovered by mankind. Some of them, known relatively recently, will be discussed in this material.
According to modern research, in those places where two different seas collide, there is a natural barrier between them. This barrier separates both seas, and therefore each of them has its own water temperature, salinity and density. (1) . For example, the water of the Mediterranean Sea is warmer, saltier and less dense than the water of the Atlantic Ocean. When water from the Mediterranean enters the Atlantic Ocean through the Gibraltar Ridge, it travels hundreds of kilometers and about 1,000 meters deep, retaining its higher temperature, salinity, and lower density. And at this depth, the water of the Mediterranean Sea continues to retain its properties. (2) .
Despite strong waves, powerful currents, ebbs and flows, these seas do not mix and do not pass through this natural barrier, thanks to surface tension. Surface tension is caused by the different degrees of density of sea water. It turns out that there is an invisible water wall separating the waters.
The Holy Quran mentions a barrier between two seas ready to meet, which, however, do not merge with each other. Allah Almighty says about it in the Qur'an (meaning):
“He separated two seas, ready to meet each other. He erected a barrier between them so that they would not merge. (Sura Ar-Rahman, verses 19-20).
The Qur'an also reports on the separation of fresh and salt water, the existence of an "insurmountable zone of separation" and a barrier between them. The Creator says in the Quran (meaning):
“He is the one who divided water into two kinds, one is fresh and drinkable, the other is salty and bitter. And He set up a barrier between them, and an insuperable border." (Sura Al-Furqan, verse 53)
One might ask why the Qur'an speaks of the existence of an "insurmountable dividing zone" when it comes to the separation of fresh and salt water, but does not mention this when it talks about the delimitation of two seas?
Modern science shows that at the mouths of rivers, where the confluence of fresh and salt water occurs, the situation is somewhat different from that observed at the confluence of two seas. Modern science has established that at the mouths of rivers where salt and fresh water meet, there is a "separation zone with a pronounced discontinuous change in density, which separates the two water masses" (3) . The water in this dividing zone differs in salt content from both fresh and salt water. (4) .
These discoveries were made relatively recently using the most modern equipment to measure water temperature, salinity, density, oxygen saturation, etc. The human eye is not able to distinguish between two merging seas. Rather, on the contrary, they appear to us as a homogeneous sea. In the same way, the human eye is not able to see the division of water in the mouths into three types: fresh water, salt water and water in the watershed zone.

There are many mysterious places and phenomena on Earth. One of such phenomena can be called a meeting of reservoirs, the waters of which do not mix. Many believe that these are the laws of physics, others consider it an inexplicable anomaly, and still others attribute such a phenomenon to the vagaries of nature.
Jacques Cousteau and the Strait of Gibraltar
In 1967, German scientists tried to find out the reasons why the waters of the Indian Ocean and the Red Sea do not mix in the Bab el-Mandeb Strait. Jacques Cousteau decided to follow the example of his colleagues and study the immiscibility of the water column of the Atlantic Ocean and the Mediterranean Sea in the Strait of Gibraltar by analyzing the density and salinity of the waters.
The scientist believed that for many millennia the waters of the two reservoirs should have mixed. But even in those places where the sea and the ocean seem to touch each other, they still retain their distinctive features.
What is the surface tension of water
As it turned out, the reason for the non-mixing of waters from different reservoirs lies in the surface tension, and this is the main parameter of water. In order not to delve into physics: this is the force due to which water molecules can connect with each other, this is how a drop, puddle, jet, etc. appear. And the stronger the surface tension, the less the volatility of the liquid.
Well, for example, alcohol has a very small molecular bonding force, so when it comes into contact with air, it quickly evaporates. Fortunately, water has a very large value for this parameter, so there is still life on our planet.
You can also visually imagine what surface tension is. To do this, take a bowl and slowly pour tea into it to the very brim. For some time, the tea will not overflow, and if you look closely, you can see a thin film on the surface of the drink, which will try to prevent the tea from spilling. This is what happens with reservoirs, each has its own surface tension, which, like a wall, prevents one reservoir from flowing into another.
Where can you see the boundaries between water bodies
In the northernmost part of Denmark, namely in the city of Skagen, the waters of the Baltic and North Seas meet. The Danes call the coastline at Skagen "the end of the world":
- Atlantic Ocean and Caribbean Sea, Antilles
- Rio Negro and Solimões rivers, Brazil
- Uruguay River and its tributary, Argentina
- Green and Colorado Rivers, Utah, USA
- Alaknanda and Bhagirathi rivers, India
- Jialing and Yangtze rivers, China
- Chuya and Katun rivers, Russia
- Moselle and Rhine rivers, Germany
- Three rivers: Inn, Danube and Ilz, Germany
- Rhone and Arve rivers, Switzerland
By the way, adherents of the Muslim faith are convinced that the reservoirs do not mix because Allah ordered so, because this was written in the Koran even before the moment when the natural phenomenon became known to science. They say that Jacques Cousteau converted to Islam only because he read about the non-mixing of waters in the Koran, and then was able to see all this in reality.
Not such a rare phenomenon is the visible boundary between communicating bodies of water: two seas, a sea and an ocean, a river and a tributary, etc. And yet, it always looks so unusual that you involuntarily wonder: why do their waters not mix?
1. North Sea and Baltic Sea
The meeting point of the North Sea and the Baltic Sea near the city of Skagen, Denmark. Water does not mix due to different densities.
2. Mediterranean Sea and Atlantic Ocean
3. Caribbean Sea and Atlantic Ocean
The meeting point of the Caribbean Sea and the Atlantic Ocean in the Antilles.
The meeting point of the Caribbean Sea and the Atlantic Ocean on Eleuthera Island, Bahamas. On the left is the Caribbean Sea (turquoise water), on the right is the Atlantic Ocean (blue water).
4. The Suriname River and the Atlantic Ocean
The meeting point of the Suriname River and the Atlantic Ocean in South America.
5. Uruguay River and its tributary
The confluence of the Uruguay River and its tributary in the province of Misiones, Argentina. One of them is cleared for the needs of agriculture, the other in the rainy season becomes almost red with clay.
6. Rio Negro and Solimões (section of the Amazon)
7. Mosel and Rhine
The confluence of the Moselle and Rhine rivers in the city of Koblenz, Germany. Rhine - lighter, Moselle - darker.
8. Ilz, Danube and Inn
The confluence of the three rivers Ilz, Danube and Inn in Passau, Germany. Ilts is a small mountain river (in the 3rd photo in the lower left corner), the Danube is in the middle and the Inn is light in color. The Inn, although wider and fuller than the Danube at the confluence, is considered a tributary.
9. Alaknanda and Bhagirathi
The confluence of the Alaknanda and Bhagirathi rivers in Devaprayag, India. Alaknanda is dark, Bhagirathi is light.
10. Irtysh and Ulba
The confluence of the Irtysh and Ulba rivers in Ust-Kamenogorsk, Kazakhstan. The Irtysh is clean, the Ulba is muddy.
11. Jialing and Yangtze
The confluence of the Jialing and Yangtze rivers in Chongqing, China. The Jialing River stretches for 119 km. In the city of Chongqing, it flows into the Yangtze River. The clear waters of Jialing meet the brown waters of the Yangtze.

The Chuya water in this place (after confluence with the Chaganuzun River) acquires an unusual cloudy white lead color and seems dense and thick. Katun is clean and turquoise. Combining together, they form a single two-color stream with a clear boundary and flow for some time without mixing.
15. Green and Colorado
The confluence of the Green and Colorado Rivers in Canyonlands National Park, Utah, USA. Green is green and Colorado is brown. The channels of these rivers run through rocks of different composition, which is why the colors of the water are so contrasting.
16. Rona and Arv
The confluence of the Rhone and Arves in Geneva, Switzerland. The river on the left is the transparent Rhone, which emerges from Lake Leman. The river on the right is the muddy Arve, which is fed by the many glaciers of the Chamonix valley.
