Incredible photos of sharp boundaries at the confluence of seas or rivers! Why doesn't water mix? Contact between the Atlantic Ocean and the Caribbean Sea The position of the Caribbean Sea within the Atlantic Ocean
Not so much a rare event- visible boundary between connected bodies of water: two seas, sea and ocean, river and tributary, etc. And yet, it always looks so unusual that you can’t help but wonder: why don’t their waters mix?
1. North Sea and Baltic Sea
The meeting point of the North Sea and the Baltic Sea near 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 region.
The meeting place of the Caribbean Sea and the Atlantic Ocean on the island of Eleuthera, Bahamas. On the left is the Caribbean Sea (turquoise water), on the right is the Atlantic Ocean (blue water).
4. Suriname River and 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 agricultural needs, the other becomes almost red with clay during the rainy season.
6. Rio Negro and Solimões (Amazon section)
7. Moselle and Rhine
The confluence of the Moselle and Rhine rivers in Koblenz, Germany. The Rhine is lighter, the Moselle is darker.
8. Ilts, 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 in the middle and the Inn of a light color. Although the Inn is wider and fuller than the Danube at its confluence, it 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.
12. Irtysh and Om
The confluence of the Irtysh and Om rivers in Omsk, Russia. The Irtysh is muddy, the Om is transparent.
13. Irtysh and Tobol
The confluence of the Irtysh and Tobol rivers near Tobolsk, Tyumen region, Russia. The Irtysh is light, muddy, the Tobol is dark, transparent.
14. Chuya and Katun
The confluence of the Chuya and Katun rivers in the Ongudai region of the Altai Republic, Russia. The water of the Chuya 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
Confluence of the Green and Colorado Rivers in National Park Canyonlands, Utah, USA. Green is green and Colorado is brown. The beds 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 Arve rivers in Geneva, Switzerland. The river on the left is the transparent Rhône, 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.
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? At the place where they touch different direction currents, as well as the difference in the level of density of 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.

From huge amount Islands of the Bahamas archipelago there is a long and very narrow island of Eleuthera, the name of which literally means “free”. This strip of land is located 80 kilometers in east direction from the capital of the Bahamas - Nassau. With a width of 1.6 kilometers, its length is 180 kilometers. On one side of the islands flow blue waters The Caribbean Sea, and on the other is the water area of the Atlantic Ocean of a pronounced dark blue color, which creates a surprisingly beautiful contrast around the island.
Glass Window Bridge is one of the best and convenient places to witness this extraordinary spectacle. The structure is located at the narrowest point of Eleuthera near Gregory Town approximately two miles from Upper Bogue. Places like this where you can compare the turquoise green waters of the shallow and calm Caribbean Sea on one side and open waters The Atlantic, rich in underwater life, on the other hand, which is separated only by a narrow strip of land, has only a few on Earth.
The concrete bridge here was built over a natural mountain bridge that connects southern and northern Eleuthera with a paved road.
Perhaps one of the most visited attractions on the island is the Glass Window Bridge.
For many centuries there was a natural connection between the southern and northern halves of Eleuthera. Around the 40s of the last century, the isthmus was destroyed due to several hurricanes, and then it was decided to build a concrete bridge here as a replacement. The artificial structure was maintained through regular repairs, thanks to which the Glass Window Bridge was well preserved. However, hurricanes in 1992 and 1999 again caused significant damage to the bridge. Particularly severe damage was caused by Hurricane Floyd, as a result of which almost nothing remained of the original structure. The bridge was, of course, rebuilt within a few months and the Queen's Highway was reconnected, but the geography of Eleuthera was changed forever. Although more than ten years have passed since this large-scale incident, workers here are still strengthening the coast of the island in order to completely pave the asphalt, which was once completely destroyed.
It should be noted that when visiting Glass Window, as well as the surrounding areas, you need to be careful and careful, since the waves arrive here unexpectedly and can completely cover the nearby cliffs and the bridge itself too. After the hurricanes, there were no reefs left along the ocean coast on the island that previously held back the onslaught and power of sea waves and ocean currents, which can strike with incredibly great force. Today, there are cases where not only tourists, but even cars were washed away from the island.
All seas and oceans and rivers on Earth communicate with each other. The water surface level 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 there is a visible contrast, a clear boundary between seas or flowing rivers.

This phenomenon is explained by differences in temperature and flow speed. The Rio Negro flows at a speed of 2 kilometers per hour and a temperature of 28 degrees Celsius, and the Solimoes at a speed of 4 to 6 kilometers and a temperature of 22 degrees Celsius.
