All seas and oceans and rivers on Earth communicate with each other. The level of the water surface is the same everywhere.
But you rarely see such a border. This is the border between the seas.
And the most amazing mergers are truly those where a contrast is visible, a clear boundary between the seas or flowing rivers.
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. The locals call it the end of the world.
Mediterranean Sea and Aegean Sea
The meeting point of the Mediterranean Sea and the Aegean Sea near the Peloponnese peninsula, Greece.
Mediterranean Sea and Atlantic Ocean
The meeting point of the Mediterranean Sea and the Atlantic Ocean in the Strait of Gibraltar. Water does not mix due to differences in density and salinity.
Caribbean Sea and Atlantic Ocean
The meeting point of the Caribbean Sea and the Atlantic Ocean in the Antilles region
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).

Uruguay and tributary (Argentina)
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.
Gega and Yupshara (Abkhazia)
The confluence of the Gega and Yupshara rivers in Abkhazia. Gega is blue, and Yupshara is brown.
Rio Negro and Solimões (cf. section of the Amazon) (Brazil)
The confluence of the Rio Negro and Solimões rivers in Brazil.
Six miles from Manaus in Brazil, the Rio Negro and Solimões join but do not mix for 4 kilometers. Rio Negro has dark water, while Solimões has light water. This phenomenon is explained by the difference in temperature and flow rate. Rio Negro flows at a speed of 2 kilometers per hour and a temperature of 28 degrees Celsius, and Solimões at a speed of 4 to 6 kilometers and a temperature of 22 degrees Celsius.
Mosel and Rhine (Germany)

Why the waters of the Pacific and Atlantic oceans do not mix, you will learn from this article.
Why don't the Atlantic and Pacific Oceans mix?
There is a place in the Gulf of Alaska where the Atlantic and Pacific oceans meet, but their waters do not mix. As you already understood, this phenomenon can be observed in the southwestern part of the coast of Alaska.
Have you ever wondered why the two oceans do not mix in the Gulf of Alaska? One reason for this is the fresh, meltwater from the glaciers that enters the ocean, which is lighter in color. Created the difference in density and level of salt in the waters of the oceans, which prevents its mixing. E then the conditional border of the Pacific and Atlantic oceans created only by a strip of foam. The scientific name for this phenomenon is halocline (salinity jump layer), which marks the transitional boundary between water with different salinity. The water of one ocean is 5 times saltier than another.
For the first time this amazing phenomenon was observed by the traveler, scientist and oceanographer Jacques Yves Cousteau, when he explored the water spaces of the Strait of Gibraltar. He showed the world the existence of 2 layers of water that do not mix with each other. The waters of the Atlantic and Pacific Oceans are, as it were, separated by a film that creates clear boundaries. And of course, they are very different from each other - each layer has its own characteristic temperature, salt composition, flora and fauna, even the color of the water. And this is the most amazing thing.
All myths cannot be broken at once, especially when they are created daily by those who wish, but as such questions come in and a small technical or analytical study is carried out, it is possible and I would even say necessary.
Just recently, one of my old acquaintances and a good friend whom I have not seen for a long time wrote to me. Nothing out of the ordinary "hello, how are you, haven't seen you for a long time", and in the text of the letter he said that he read my works and decided to ask a question that had tormented him for a long time - Why in some places fresh and salty sea water does not mix. Thus, the topic for the next post in LabOrder (laboratory of orders) was determined.
I have already come across this issue, and often in conversations with the same people - religious, who at every opportunity mentioned that the Holy Quran says not to mix fresh and salt water, and used this statement as an argument in favor of the fact that this book knows something that science still cannot explain. Previously, I simply dismissed such "arguments" due to the fact that I am an agnostic, and I have an irreparable conviction that often religion either misinterprets physical phenomena, or creates and demonstrates certain tricks in order to attract more adherents to its ranks. But since a person asked, especially my old friend - let's figure it out.
To begin with, let's ask the holy book what it says about immiscible waters, specifically and in the text. Why text? Often, everyone interprets certain words, in an incomprehensible translation, and wishful thinking.
Since this sura consists of 77 ayat, we will consider only the ayat that we need where this statement about not mixing water is mentioned. ayat
<<25:53. Аллах - Тот, кто создал два моря рядом: в одном море - пресная вода, а в другом море - солёная. Оба моря рядом друг с другом, но Он поставил нерушимую преграду между ними, и они не смешиваются благодаря благоволению Аллаха и Его милосердию к людям>>
But even on this site, the substitution of concepts and the reinterpretation of original statements are already underway. From which I ask people who read such literature to be careful. Here, for example, is the translation of the Quran by Valeria Porokhova (Al Furqan 25:53):
<<Он - Тот, Кто в путь пустил два моря:
Pleasant and fresh - one,
Salty and bitter - another.
He put a barrier between them -
Such an unbreakable barrier
(Which never allows them to merge)>>
It should also be noted that this phenomenon is repeated in sura ayat 19-20.
Pleasant and insipid - Salty and bitter. Well, now you can more or less reliably see what, where and where. It is quite possible that the example with the seas is a metaphor and nothing more. But let's even say that.
In general, I repeat that the main argument is often that the Holy Book mentions the truth that was not yet known to science until now. And they even say that the famous scuba inventor and oceanographer Jacques Cousteau converted to Islam when he first saw this phenomenon in reality. But I'm afraid it might not happen, as with the astronaut Armstrong.
In order to begin to understand this problem, we need to list the places on the planet and the conditions in which a similar phenomenon is observed, where water from one reservoir does not mix with water from another.
<< Галоклин - слой воды, в котором солёность резко изменяется с глубиной (наблюдается большой вертикальный градиент солёности). Один из видов хемоклина. Ввиду того, что солёность влияет на плотность воды, галоклин может играть роль в её вертикальной стратификации (англ.) (расслоении). Повышение солёности на 1 кг/м3 приводит к увеличению плотности морской воды приблизительно на 0,7 кг/м3 >>
<<…А. И. Воейков впервые дал верное объяснение наличию теплой воды на глубинах северной части Индийского океана. Он утверждал, что В БАБ-ЭЛЬ-МАНДЕБСКОМ ПРОЛИВЕ ДОЛЖНО СУЩЕСТВОВАТЬ НИЖНЕЕ ТЕЧЕНИЕ ОЧЕНЬ ТЕПЛОЙ И СОЛЕНОЙ ВОДЫ ИЗ КРАСНОГО МОРЯ В ИНДИЙСКИЙ ОКЕАН. Впоследствии это БЫЛО ДВАЖДЫ ПОДТВЕРЖДЕНО НАБЛЮДЕНИЯМИ в указанном проливе: во время плаваний С. О. МАКАРОВА на «Витязе» в 1886-1889 гг. И АНГЛИЙСКОЙ ЭКСПЕДИЦИЕЙ на судне «Старк» в 1898 г.>>
2) Strait of Gibraltar - between the Iberian Peninsula and the northwestern coast of Africa, connecting the Mediterranean Sea and the Atlantic Ocean.
If you believe this photo, then it was taken in this very place. And the interface that is visible on it is the difference in salinity, which for some reason does not mix.
Again, there are no reliable sources of information that this phenomenon can be observed in this form as shown in the picture above, again, except for you know which sites. Moreover, in different sources this image is attributed to a different location. Okay, let's see where we have "fresh" here and where there is "salt". The Atlantic Ocean is salty, as well as the Mediterranean Sea, which is more salty than the ocean itself. It has been established that the water exchange between these two reservoirs along the upper reaches brings 42.3 thousand km3 to the Mediterranean Sea, and the lower reaches 40.8 thousand km3 of water per year from the sea. What kind of "non-mixing" of water is in question here, one can only guess.
Also, if you believe Valeria Porokhova herself, this barrier and a clear separation is observed in almost every river that flows into any sea (on video from 2:00). Yeah, especially when it comes to the Volga and the Caspian Sea, where could the astronaut see the dividing line there? History is silent.
Watch your hands.
Obviously, and most likely, the first thing that surprises people is the clear interface that is shown in the photographs to confirm that the water does not really mix. But my dears, how can water not mix if the world water exchange is almost a fundamental law. Only partly, a relatively blurred interface can be observed due to a number of physical phenomena that can be observed either temporarily or at different depths depending on the changing water temperature, salinity, surface tension and currents carrying it at different speeds, thereby slowing down the diffusion process. I repeat, regarding the clear dividing line that some people claim and the lack of water exchange, in such places, alas, there are no official and reliable sources.
Why not bring in confirmation of an isolated lake that would have a similar clear division, a "sweet - slide" of water. Maybe because it doesn't exist?
Increasingly, it is the straits and connections of rivers with the seas that are cited as an example. As a result of the connection of two different waters, where the phenomenon appears on which the diffusion process takes place according to the above factors. Why, for example, is no one surprised by such a boundary found in nature?
Maybe because these obvious things were simply not written in Scripture?
On the other hand, no one claims that in the Holy Book, there is generally a detailed explanation of anything except - it was done by God and in His Name!
What is the root of this trick? Yes, in the fact that 1400 years ago this was already described in the Koran, and science is only now making such discoveries. Well, okay. Science simply, besides making discoveries, tries to explain them, by the way, its key difference from any religion, which simply points to God.
That is, what do deeply religious people want to convey to us? And the fact that 1400 years ago, the only one who knew that when two water tanks were connected there would be no dividing line, it was the Holy Scripture of the Koran. And until this moment, for some reason, no one noticed this phenomenon among people who have already been using the fleet with might and main for at least 4000 years. That's it.
And finally, watch this video (I did not give the name to it). Do you still think that deeply religious people who mix reality with faith are capable of professionalism in a particular profession? Especially such as pilots, doctors, scientists, physicists, teachers, designers, etc. ..?
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.
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?
