Which seas do not mix and why. About all the knowledge of the sacred books or why the two oceans do not mix
Miracle of the Qur'an: the seas that do not mix
Sura 55 "The Merciful":
19. He mixed the two seas that meet each other.
20. There is a barrier between them that they cannot cross.
Sura 25 "Discrimination":
53. He is the One Who mixed two seas (types of water): one is pleasant, fresh, and the other is salty, bitter. He placed a barrier and an insurmountable obstacle between them.
While exploring the expanses of water in the Strait of Gibraltar, Jacques Cousteau discovered an amazing fact, not explained by science: the existence of two water columns 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 own salt composition, flora and fauna. These are the waters of the Mediterranean Sea and the Atlantic Ocean touching 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. First we examined the water of the Mediterranean Sea - its natural level of salinity, density and the life forms inherent in it. We did the same thing 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 mixed long ago - their salinity and density should have become the same, or at least similar. But even in the 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.”
When he discovered this obvious and incredible fact, the scientist was extremely surprised. “For a long time I rested on the laurels of this amazing phenomenon, inexplicable by the laws of physics and chemistry,” writes Cousteau.
But the scientist experienced even greater surprise and admiration when he learned that this was written about in the Koran 1,400 years ago. He learned about this from Dr. Maurice Bucaille, a Frenchman who converted to Islam.
“When I told him about my discovery, he skeptically told me that this was said in the Koran 1400 years ago. It was like a bolt from the blue for me. And indeed, this is how it turned out 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 man. This is the true speech of the Almighty.” After that, I accepted Islam and every day I was amazed at the truth, justice, ease, and usefulness of this religion. I am eternally grateful that He opened my eyes to the Truth,” Cousteau further writes.
Why do the waters of the Atlantic Ocean and the Mediterranean Sea not mix when they meet in the Strait of Gibraltar? Of the 23 groups studied in the Gulf of Alaska, 18 consisted of whales of similar sizes, and only the remaining 5 were of different sizes. The stomach of the sperm whale, like that of all toothed whales, is multi-chambered.
However, even in places where the waters converge closest, they nevertheless retain their properties, i.e. don't mix. How can they not mix if in both cases the solvent is water? Do not contradict the laws of thermodynamics! A photo with a sharp boundary does not mean anything, even if it is a photograph in the area of the strait, etc., it is simply a recording of some moment of mixing. This is called a halocline or salinity jump layer - a transitional boundary between waters of different salinity.
Most maps do not indicate the boundaries of the seas, so it seems that they simply smoothly pass into each other and into the oceans. The boundaries of the seas (or sea and ocean) are most clearly visible where a vertical halocline appears. A halocline is a strong difference in salinity between two layers of water. Jacques Cousteau discovered the same phenomenon while exploring the Strait of Gibraltar.
For a halocline to arise, one body of water must be five times saltier than another. In this case, physical laws will prevent the waters from mixing. Now imagine a vertical halocline that occurs when two seas collide, one of which has a salt percentage five times higher than the other. This is where you will see the place where the North Sea and the Baltic Sea meet.
They also cannot mix right away, and not only because of the difference in salinity. In other places, water boundaries also exist, but they are smoother and not noticeable to the eye, since the mixing of waters occurs more intensely. White_raccoon: it is at the Cape of Good Hope that the Atlantic and Indian currents meet. A wave that has passed the entire Atlantic can meet a wave that has passed through the entire Indian Ocean, but they will not cancel each other out, but will go further and reach Antarctica.
This is the mixing of the waters of the Gulf of Alaska with the open waters of the Pacific Ocean.
The sperm whale is a herd animal, living in large groups, sometimes reaching hundreds and even thousands of heads. It is distributed throughout the world's oceans with the exception of the polar regions. In nature, the sperm whale has practically no enemies; only killer whales can occasionally attack females and young animals.
Descriptions of the sperm whale are found in famous authors. Linnaeus cited two species of the genus Physeter in his work: catodon and macrocephalus. The weight of the “spermaceti sac” reaches 6 tons and even 11 tons. Behind the head, the body of the sperm whale expands and in the middle becomes thick, almost round in cross-section.
The border is outlined with a thin layer of foam.
When the sperm whale exhales, it produces a fountain directed obliquely forward and upward at an angle of approximately 45 degrees. At this time, the whale lies almost in one place, only moving forward a little, and, being in a horizontal position, rhythmically plunges into the water, releasing a fountain. The color often contains brown tones (especially noticeable in bright sunlight); brown and even almost black sperm whales are found. In the past, when sperm whales were more numerous, specimens weighing close to 100 tons were occasionally encountered.
Two harpoons belonging to the crew of the Anne Alexander were found in the sperm whale carcass.
The difference in size between male and female sperm whales is the largest among all cetaceans. The size of the heart of an average sperm whale is a meter in height and width. The sperm whale's spine has 7 cervical vertebrae, 11 thoracic, 8-9 lumbar and 20-24 caudal vertebrae. It consists of two main parts filled with spermaceti.
Back in the 1970s, studies appeared that showed that the spermaceti organ regulates the buoyancy of the sperm whale when diving and rising from the depths. However, both liquid and solid spermaceti are significantly lighter than water - its density at 30 °C is about 0.857 g/cm³, 0.852 at 37 °C and 0.850 at 40 °C.
Males are found over a wider range than females, and it is adult males (only they) that regularly appear in subpolar waters. Sperm whales are more common in warm waters than in cold ones. Leay, 1851), living in the northern and southern hemispheres, respectively. Whales of this stock stay off the Pacific coast of the United States all year round, but reach their maximum numbers in these waters from April to mid-November.
Hawaiian. During the summer and fall, this herd stays in the eastern Pacific Ocean
Its habitat is the Bering Sea, well separated from the main part of the Pacific Ocean by the ridge of the Aleutian Islands, which the sperm whales of this herd rarely cross. Most sperm whales can be found here in the fall in the waters of the New England continental shelf. Modern sperm whales appeared about 10 million years ago and, apparently, have changed little during this time, during which they have remained at the top of the ocean food chain.
The colossal pressure of water at depth does not harm the whale, since its body largely consists of fat and other liquids that are very little compressed by pressure. There are suggestions that the sperm whale uses echolocation not only to find prey and navigate, but also as a weapon. Thus, according to Soviet research, up to 28 species of cephalopods were found in the stomachs of sperm whales from the waters of the Kuril Islands (360 stomachs).
But female sperm whales were also very thoroughly killed in the years after World War II, especially in the waters washing the coasts of Chile and Peru
In the 1980s, it was estimated that sperm whales ate about 12 million tons of cephalopods per year in the waters of the Southern Ocean. A case is described in which a sperm whale was caught that had swallowed a squid so large that its tentacles did not fit in the whale’s belly, but stuck out and attached themselves to the sperm whale’s snout. An adult male sperm whale, with its enormous strength and powerful teeth, has no enemies in nature. There are different estimates of the current number of sperm whales in the World Ocean.
Sea pollution is an important factor influencing the number of sperm whales in a number of areas of the World Ocean.
Be that as it may, the number of sperm whales so far, especially in comparison with the number of other large whales, remains relatively high. The harvest of sperm whales was sharply limited in the second half of the 1960s, and in 1985, sperm whales, along with other whales, were completely protected.
According to some estimates, between 184,000 and 230,000 sperm whales were taken in the 19th century, and about 770,000 in the modern era (most of them between 1946 and 1980). All sperm whales were caught in the Northern Hemisphere. Before attacking the ship, the sperm whale managed to destroy two boats. Fortunately, there were no casualties, as the crew was rescued two days later. In 2004, data was published that from 1975 to 2002, sea vessels collided with large whales 292 times, including sperm whales 17 times. Moreover, in 13 cases, sperm whales died.
Jacques was impressed by the fact that this place was written about in the Koran 1,400 years ago. After this, he was attracted to the religion of Islam. The point here is surface tension: transport?r - what is the meaning of this word, in what language is it written? Here you can see a clear boundary between waters of different salinity.
Northern Gulf of Mexico herd. But, despite the spectacular border of these two seas, their waters gradually mix. Cousteau, having traveled a lot, discovered a place where the waters of the Mediterranean Sea and the Atlantic Ocean touch in the strait, without mixing with each other.
A not-so-rare phenomenon is a visible boundary between connected 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 can’t help but wonder: why don’t their waters mix?

They say that the Atlantic and Pacific oceans do not mix their waters. It is quite difficult for us to understand how identical liquids cannot combine. In this article “I and the World” will try to figure this out.
Of course, to say that the waters of the oceans do not mix at all is wrong. So why is the border between them so clearly visible? In the place where they touch, the direction of the currents is different, as well as the difference in the level of density of the water and the amount of salt in it. At the line of their intersection it is even clearly visible that the colors of the reservoirs are completely different. This joint is clearly visible in the photo.
The famous scientist Jacques Cousteau once spoke about the directions of currents, when the force of the earth at an angle to the axis of rotation prevents the waters from completely mixing at the place where they meet. But what’s interesting is that this phenomenon was written about in the Koran 1400 years ago.
The invisible merging of the oceans occurs only in the Southern Hemisphere, since in the Northern Hemisphere they are separated by continents.
Such clear boundaries can be seen not only where oceans meet, but also seas and between river basins. For example, the North and Baltic seas do not mix due to the different densities of their waters.
At the confluence of the Irtysh and Ulba, in the first river the water is clear, in the second it is muddy.
In China: the clean Jialing River flows into the brown-dirty Yangtze.
The two rivers, having traveled almost 4 km, still do not mix. This is explained by the different speeds of their currents and temperatures. The Rio Negro is slower and warmer, while the Solimões flows faster, but is cooler.
And there are many such examples. From the outside, all this seems mystical, until an exact explanation comes.
