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.

“Sea, sea... Bottomless world!” - these words from a once popular song excite our imagination with romantic pictures of seascapes with blue distances, blue skies and turquoise waves.

Which sea is the bluest?(The answer is at the very end of the post).

Somewhere in our souls our distant warm sea begins to rustle, echoing the rustling waves in summer sea fantasies...

How many oceans and seas are there on our planet?

According to the International Geographical Bureau, there are 4 oceans and 54 seas on Earth, which together form the World Ocean, which makes up two-thirds of the surface of the entire globe.

What color is the ocean?

The color of sea water in the World Ocean is far from uniform, and it is different in different parts of the Earth, that is, each sea has a unique color shade, unique to it.

What determines the color of the sea?

The color of the water changes periodically, and this depends on many factors, primarily on lighting, depth, transparency, color of the seabed, the presence of gases and the quantitative density of microorganisms inhabiting the sea, as well as on phenomena such as glow and sea blooms. In the distance, the color of the sea is close to the color of the sky. In cloudy weather it is gray, in clear weather it is blue. When the Sun sets, the bright blue sea takes on a golden hue. During waves, the sea appears whitish.

Scientists studying depths of the sea, claim that many seas got their name due to the color of the water. They believe that in warm seas in the tropical zone, the color of the water is dark blue, and even blue; in shelf seas, it is greenish, and in muddy coastal seas has a yellowish tint.

Why is the White Sea called white, the Black Sea black, the Red Sea red, and the Yellow Sea yellow?

The White Sea is the sacred sea of ​​the North, it conceals a lot unsolved mysteries.

The White Sea probably got its name from the color of the white snow and ice that covers it in winter. But there is another assumption, which is that the name “White” Sea received from the religious meaning of the sphere, that is, the heavenly one.

After all, in semantics White color- this is a heavenly, divine color. There is a hypothesis that the White Sea and its coast are located on the territory of a once thriving mystical civilization - Hyperborea.

The Black Sea got its name because in cloudy weather the surface of the sea darkens under black clouds. The Turkic nomads, who noticed this, gave it the name “Kara-Deniz”.

There is another plausible assumption about the origin of the name of the Black Sea. It has been known since ancient times that all objects that have been in its mysterious depths turn black. And this happens because at a depth of more than 200 meters, sea water is saturated with hydrogen sulfide, which easily forms black salts.

The Red Sea is red in color due to brown microscopic algae that periodically develop in it. But there is another version regarding the name of the Red Sea. They say that in ancient times, sailors gave the sea the name “Red” because of the color of the rocks with which it is surrounded.

There is an ancient legend related to biblical events, which tells about the difficult transition of the Jews from Egypt to Israel through the Red Sea.

Moses, who led the Jewish people, ordered in God's name part to the sea waters. And before their eyes, the deep bottom of the sea opened up with rocks and mountain ranges, with gorges and depressions, during the passage through which a lot of people died, which was the reason for the name of the Red Sea.

The Red Sea is one of the clearest and saltiest seas. Its crystal purity is explained by the fact that not a single river flows into it, which could bring silt and sand with it and, thereby, cloud the sea waters. And although the sea is called Red, its waters have a beautiful azure color.

The Yellow Sea is so named because the clay that is abundant on the coast periodically acquires a yellowish tint.

Is it possible to determine the color of the sea?

The first device for determining the color of reservoirs was invented at the end of the 19th century by the Swiss geographer Forel, who was studying lakes. The device was somewhat inconvenient for working with sea water.

The famous German oceanographer Ule developed a water color scale, consisting of a set of twenty-two glass sealed test tubes with samples of solutions of different shades, from light aquamarine to brownish green. Ole modified the device, improved it, and in given time Using this device you can determine the color of sea water.

Of course, if you take sea water into your palm, it will turn out to be transparent, having no color at all. And only in the sea or ocean does it acquire its unique shade.

Which seas have the most green color water?

There are amazing things on Earth beautiful seas with eye-catching fairy-tale shades. These sea beauties include the Sargasso Sea.

The Sargasso Sea has a bright greenish tint due to the accumulation of green algae on its surface, which form entire islands, roads, and even fields. And the sailors who found themselves in this area of ​​the ocean for the first time mistakenly took it for land.

One of the most vibrant tropical seas is the Caribbean Sea. Its water shines from deep turquoise to bright emerald shades.

The Sea of ​​Azov also has a greenish tint, especially during the plankton development season. And during the storm season, the sea takes on a color from yellow-green to yellow-brown due to changes in water transparency. The sea begins to become cloudy because the bottom silt periodically becomes agitated and the river flow of turbid waters increases.

And what color shades do people for whom the sea is a place of everyday work notice in sea waters?

Those who have connected their lives with the sea see and notice the sea and ocean waters the most extraordinary subtle shades. After all, the sea changes with the time of day, its color depends on the seasons and weather factors. When the character of the sea changes, its color also changes. And these changes cannot be ignored.

Some of the most vivid impressions include memories of a holiday at sea. What is it about this beautiful sea element that we remember? The gentle rays of the southern sun? The soft velvet of coastal sand? The rustling whisper of the waves or the warm breath of the salty wind?..

Perhaps, among all these soul-intoxicating memorable moments, the most powerful is the color of the sea. This fantastic blue, delighting our admiring gaze, remains in our memory as an aquamarine delight, a turquoise fairy tale or an azure legend. And all the picturesque shades of the sea merge into one wonderful sea color, with which any memory of the sea is associated.

If you try to answer the question, which sea is the bluest, it is unlikely that you will come to one single true answer. After all, each sea has its own unique color from the blue range with unique shades of turquoise, aquamarine or emerald.

The bluest sea is the sea that lives in our joyful memories or sweet dreams of beauty.
And dreams certainly come true...

All beach lovers know that there are not many paradise and amazing places in the world that are ideal for complete passive relaxation. The main requirements of such tourists are the cleanest warm sea, soft sun and white beaches. Just a couple of years ago, tourists beach holiday We went to Turkey and Thailand. Today, the boundaries and opportunities for true beach lovers have expanded. Tours to countries are popular in autumn and winter Caribbean, because natural conditions in these places are unique. One of the most visited countries has become Dominican Republic .

Why Dominican Republic

The Dominican Republic is a dream country. Tall palm trees, turquoise Caribbean sea, white sandy beaches, mild tropical climate - all this creates amazing conditions for complete relaxation.

There are no suitable words to describe the beauty and grandeur of the Caribbean Sea. Most tourists visit this country just to see this divine sea with their own eyes. Its bright turquoise color is simply stunning. Soft waves and very warm water – the sea envelops you with its warmth. This sea will forever remain in your memory. Since the Dominican Republic is not yet the most popular tourist destination, the sea here remains very clean, and the landscapes amaze with their pristine nature. Along the coast you can still find quiet places where you can retire and be alone with nature. Many beaches are equipped with sun loungers.

Service in the Dominican Republic is at a high level. There are many hotels to choose from. From food you can choose dishes national cuisine, which includes various meat dishes, or order those delicacies that you are used to at home. Dominicans are very friendly, always ready to solve any problem.

As for entertainment, you can try any kind sea ​​trips, fishing, or play beach volleyball. Among the attractions, you can choose excursions to museums or a fort named after Columbus. A lot is connected with the name of this traveler, since it was on these lands that he once landed.

As soon as you step onto Cancun Beach, the bright turquoise ocean opens up to your eyes. Therefore, I would like to separately describe how beautiful the Caribbean Sea is in Cancun. It seems to me that only Nana Maldives sea ​​water can be such a bright color. You stand on the shore and cannot believe that this is possible in nature!

Beach Cancun Beach

The color of the water of the Caribbean Sea captivates everyone! And after that, I think people become more picky about water if they fly to, for example, Bali on their next trip. The sand, the entry into the sea, the depth, purity and color of the water are all at the highest level.

Waves

The waves in Cancun on the Caribbean coast are not small, but the beauty that a person sees in front of him outshines these waves and you jump joyfully with happiness. You won't be able to swim, but jumping in the waves near the shore is also fun. Perhaps this is a seasonal phenomenon.

Algae on Cancun Beach

Seaweed

There is algae almost all over the beach, which they do not have time to quickly remove. At first it was embarrassing and not very pleasant, but on the second day you accept it and don’t pay attention anymore. At our Oasis Cancun hotel, the perimeter of the beach is perfectly clean, the cleaners work tirelessly. In the mornings, algae is collected on a tractor.

Purity

Or maybe the contingent of people coming to Mexico is somewhat different, so in Cancun you won’t see bags, bottles, chips packages floating and rotting in the water, or other dirt; this is not the case here. Our impressions of this resort are described in detail in the article

Red sea

Yellow Sea- semi-enclosed marginal sea Pacific Ocean at east coast Asia west of the Korean Peninsula. The name comes from the color of the water caused by sediment from Chinese rivers and dust storms. In spring, yellow dust storms are so strong that ships have to stop moving.

The Yellow Sea forms the West Korean, Liaodong and Bohai Gulfs. Mostly coastline calm, composed of alluvial deposits. There are convenient harbors on the coast of the Liaodong and Shandong Peninsulas. The Yellow Sea itself is shallow, especially in the western part, where the Yellow River flows into it, carrying a huge amount of silt and eroded loess (hence the names: Yellow River - Yellow River, Huanghai - Yellow Sea).

Which seas have the greenest water color?

There are amazingly beautiful seas on Earth with eye-catching fairy-tale shades. These sea “beauties” include Sargasso Sea.

And if you try to answer the question, which sea is the bluest, it is unlikely that you will come to one single true answer. After all, each sea has its own unique color from the blue range with unique shades of turquoise, aquamarine or emerald.

The bluest sea is the sea that lives in our joyful memories or sweet dreams of beauty. And dreams certainly come true...

The very best...

The deepest sea in the world is the Philippine Sea, whose area is more than 5.7 million km2. The greatest depth here reaches 10265 m.And the shallowest is the Yellow Sea, where the depth does not exceed 100 m.

The largest surface area is occupied by the waters of the Sargasso Sea - about 7 million km2. The White Sea is the smallest among the ocean seas. The area of ​​its water surface is only 90 thousand km2.

The Red Sea is the warmest and saltiest sea on the planet. The strongest evaporation of sea water occurs from its surface compared to other seas. It is curious that not a single river flows into this open sea. Maybe for this reason, the Red Sea holds the lead among the most polluted seas in the world.

The record for the transparency of sea water on the planet was recorded off the coast of Antarctica, in the Weddell Sea. Here the water is the purest, almost like distilled water. The white object, lowered to a depth of 79 m, remains visible to the naked eye.Among the seas washing other parts of the world, the most clear water in the Mediterranean Sea. The contours of a white object differ in it at a depth of 53 m. Extremely clear water in the ocean expanses of the planet was discovered in 1987 in the eastern part of the Guiana Basin in the thickness of the Atlantic at a depth of 4 km.

And the saltiest sea water is at a depth of 150 m in the Gulf of Mexico off the coast of the American state of Louisiana. In this pit with an area of ​​24 km by 15 km, its salinity is approximately 10 times higher than the average salinity of sea water.

The highest gold content in sea ​​water recorded in the Baltic Sea. There is 3 times more precious metal here than in the waters of the North Sea, and 5 times more than in the Black Sea. The average gold content in seawater is 0.000004 g/t.

The largest model of part of the planet's aquatic environment was built in 1971 in Japan. It reproduces in detail the Inland Sea of ​​Japan. The dimensions of the model are 230 m by 100 m. The model serves as a testing ground for the implementation of planned ocean development projects and various environmental measures.

In ancient times, the Baltic Sea was called the Amber Sea because of the abundance of amber in it.

Researchers of the Caspian Sea note that this sea had the largest number of names - about 70 names: Avar, Vostochnoe, Chirkan, Khvalynskoe and others, which reflected the history and geography of its coasts. The name of the Caspian Sea is associated with the name of the Caspian tribe, who lived on its shores in ancient times.

Interesting:

Poets, artists, novelists sang the ninth wave as the largest among the raging waves. But in reality there is no ninth shaft. It is easy to verify this by counting the number of intermediate waves between the two largest ones from the side of the ship or from the shore. The biggest wave can be any one. But where did the name “ninth wave” come from? It arose in ancient times from the mythological idea of ​​nine as a sacred number.
