One of my favorite school books is the novel “ Quiet Don". Therefore, I associate this river with the Cossacks, with their free life, with the beauties of nature. And what kind of river is this, where does it originate from and where does it end?
The source and mouth of the Don
Oddly enough, in different time different lakes were considered the source of the Don. Once it was called the source of the lake Ivan. This assumption was later refuted. Now the place where the Don originates, we know for sure. It located in Novomoskovsk. There is even an architectural monument called "The Source of the Don". However, even now many people mistakenly consider it to be the source of the Shatsk reservoir, next to which it flows.
And where does the Don flow? There is only one answer to this question - to the Taganrog Bay of the Azov Sea. Once I managed to visit the Sea of Azov. It is completely unlike other seas on which I was lucky enough to rest. It is very shallow, due to which it warms up strongly with the sun's rays. You can enter it far, far, and the water does not even reach the neck.
Here the river bed is divided into many branches, the delta of which covers an area of as much as 540 sq. km. The largest of them are:
Don River: what is it
The river valley is flat, there are no high rapids. Its floodplain is wide enough. In the lower reaches, the width reaches 15 km. The Don River flows calmly, without haste. It is no coincidence that Sholokhov called Don quiet!
As for the water regime of the river, despite the vast catchment area, the water content of the Don is not large. This is mainly due to the fact that the river flows in the steppe and forest-steppe. The water level along the entire length of the river is 8-13 m.
V economic activity human Don is actively involved. This river is one of the most important waterways of communication. Here you can constantly find ships.
An interesting feature of the river is flood, passing as if in two waves. The first is "cold" when melt water gets into the river from the lower reaches. The second is "warm" when waters come in large quantities from the upper course.
Location: between the Arabian Peninsula and Africa
Washes the shores of countries: Egypt, Sudan, Djibouti, Eritrea, Saudi Arabia, Yemen, Israel, Jordan
Square: 438,000 km²
Maximum depth: 2211 m
Coordinates: 20 ° 44 "41.1" N 37 ° 55 "27.9" E
The Red Sea, located in a tectonic depression and is the third largest inland sea on our planet Indian Ocean, is considered the youngest and most interesting in terms of the diversity of flora and fauna.
It is located between the African continent and the Arabian Peninsula. Red Sea connects with Mediterranean Sea and the Indian Ocean, through the well-known Suez Canal.
Speaking about the Red Sea, attention should be paid to the fact that it is considered the saltiest of all the seas that are part of the World Ocean, washing all the continents of our planet.
“Why is this sea the saltiest of all seas?” - a person who does not know too well the geography and location of the Red Sea may ask a question. The thing is that the Red Sea is the only sea in the whole world, into which not a single freshwater river flows. Naturally, it is significantly inferior in salt content to the Dead Sea, but it should be remembered that almost no living organism is able to survive in the Dead Sea, and the Red Sea amazes even experienced divers with an abundance of life forms. And this despite the fact that the salinity of the magnificent Red Sea water is up to 60 grams of salt per liter of water taken for laboratory analysis.
As a comparison, it is worth mentioning the salinity of the water, which is popular among domestic tourists on the Black Sea - it is only 18 grams of salt per liter of water.
In addition, describing the Red Sea, which is rightfully considered one of the seven wonders of the underwater world, it is impossible not to mention that this is also the warmest sea on the planet. It is warmed not only by the rays of the sun, but also by the earth's mantle, that is, in the Red Sea, unlike other seas, not cold, but warm layers of water rise from the depths. In winter, the water warms up to 21 - 23 degrees Celsius, and in summer up to +30. Due to the high temperature of the water and its constant evaporation, the Red Sea became the saltiest in the world, naturally, after the Dead Sea.
The origin of the name of the Red Sea
The Red Sea, according to the most modest assumptions of scientists, originated 25 million years ago... Therefore, it is, alas, impossible to find out exactly why the Red Sea was called "Red". There are only a few versions of the origin of the name of the Red Sea, although it is worth mentioning right away that none of them can be considered reliable.
According to the first version, the name comes from the ancient language of the Himyarites - a people who lived in South Arabia long before these lands were captured by the Arabs. The conquerors tried for a long time to decipher the writing of the Semites and decided to read the three letters "X", "M" and "P" in their own way - "Ahmar", which in translation means red. This assumption can be considered as a version that does not deserve special attention: it is difficult to imagine that the Arabs decided to add vowels to a foreign language in order to get a word that would be familiar to them, because they were engaged in deciphering the language, and not merging it with their own.
The second version, according to historians, is more plausible, although it is associated with the myths of many peoples who inhabited the territory near the Red Sea. Each of the parts of the world was associated with a certain color. The color red was associated with the south, where the sea was located, hence its name. According to documents that have survived to this day, and were deciphered by scientists, the Red Sea was mentioned as early as the 2nd century BC, and in the 16th century, some researchers called this sea, which is part of the Indian Ocean, the Suez Sea.
As mentioned above, the sea was formed even when India began its movement towards Asian mainland, and this event happened long before the appearance of the first man on Earth, therefore, scientists will certainly not be able to find out for certain why the saltiest sea, which is part of the World Ocean, was named "Red".
Long history of the youngest sea
Over the entire period of its existence, the Red Sea, despite its young age (naturally, according to geological standards), has experienced a number of changes and cataclysms. For 25 million years, which for our planet can be considered only for a short moment, the level of the World Ocean has constantly fluctuated, which, by the way, is happening now. Glaciers melted, new ones formed; the waters of the oceans rose and fell tens or even hundreds of meters. As soon as the level of the World Ocean dropped significantly, the Red Sea turned into a huge salt Lake, where the salt content was several times higher than the amount of salt per liter of water in the Dead Sea.
By the way, at the moment the sea connects the Bab-el-Mandeb Strait with the ocean. The most deep place strait - 184 meters. One has only to imagine what will happen if a new ice age begins and the level of the World Ocean falls by 190 meters. The Red Sea will cease to communicate with the waters of the Indian Ocean and will once again become dead. However, this does not threaten our contemporaries and descendants. Such a decrease in the level of the World Ocean has been happening for hundreds of thousands of years, so the amazing beauty of the sea that washes the shores of Sudan, Israel, Saudi Arabia, Jordan and, of course, Egypt will delight everyone who wishes to see all the wealth of the underwater world that can only be found in the Red Sea or on the Barrier Reefs.
Scientists have found that the Red Sea quite often lost its "connection" with the World Ocean, and its coast dried up and was covered with salt. As a result, even now, on the shores of the Red Sea, alas, you will not find lush vegetation, and you will not be able to quench your thirst from a spring that gushes. The underground water tastes salty too. Surprisingly, even the rains in the Red Sea region will not give life-giving moisture to the soil, they, like the sea and the springs near it, are salty.
Forest by the Red Sea
Yes, dear reader, you heard right at all, in the northernmost part of the Red Sea there is a forest consisting of mangroves. This forest is included in the reserve called Nabq. Only mangroves are able to grow in salt water and do not need constant access to the oxygen root system.
This amazing plant is able to remove excess salt through its leaves, and life-giving fresh moisture nourishes the wood. Mangroves usually grow together in such a way that it is rather difficult for a person to get through them, and once in a certain area, you can easily find yourself in a trap, from which it is impossible to get out without outside help. The mangroves of the Red Sea are home to a huge number of animals and birds, and bird watchers and zoologists monitor their lives in the reserve.
Flora and fauna of the Red Sea
If you say that The Red Sea is a real paradise for divers, anglers and spearfishers., this will not be an exaggeration. One has only to put on a mask and take a snorkel, as already at the very coast you can see a fascinating underwater world with many colorful corals, sponges, sea urchins and fish.
Sometimes it seems that each species is competing here with each other in the brightness of color and unusual shapes. The warm and crystal clear waters of the Red Sea allow many species of underwater flora and fauna to exist here, most of which are endemic. Life under water is in full swing here and does not stop even in the middle of the night.
To date alone, scientists who conduct research into the depths of the Red Sea have discovered and described almost 1,500 invertebrates, and almost the same number of fish species. Almost 300 species of coral live in the waters of the Red Sea, the reproduction of which is a fantastic picture.
Huge sea turtles and frolicking dolphins complement the amazing landscape and tell the tourist that he has come to a place where the underwater life reveals itself to a person in all its glory.
It is surprising that, according to ichthyologists, no more than 60% of the underwater inhabitants of the Red Sea have been discovered in our time. The deepest sea in this unique of its kind is more than 3 kilometers, which means that most deep-sea fish are not yet known to science. So far, only forty-three species of fish living at great depths have been discovered. Also, the Red Sea constantly poses more and more mysteries to scientists. It is still unknown why about 30% of the inhabitants of the northern part of the sea cannot live in another part of it.
One gets the impression that an invisible border prevents them from moving from north to south. Although the chemical composition of water and the temperature regime in these areas are almost identical. Maybe the reason lies in the word "almost"? ...
Despite the extraterrestrial beauty of the underwater world, the Red Sea is fraught with dangers... It is strictly forbidden to touch the beautiful corals, sponges or fancy jellyfish in the sea. This is written about in almost every tourist brochure. An injection sea urchin or the bite of a poisonous underwater snake, a toothed moray eel can lead to burns, an allergic reaction, large blood loss, and sometimes even death of the victim.
As you dive into the depths of the Red Sea, remember that it is home to 44 shark species. Some of them are quite harmless creatures that live only at great depths and feed on plankton or small fish. However, among them there are also the most dangerous species for humans, for example, the tiger shark, which often attacks humans for no apparent reason. Its mouth is dotted with huge sharp teeth that can easily tear off a limb. Alas, in recent years, attacks of tiger sharks on vacationers have begun to be observed more and more often, which, for the most part, most often ended fatally. There is evidence that a large white shark, which is, even according to scientists, a killing machine.
The water of a mesmerizing azure color, with a visibility of several tens of meters - some water bodies of the planet are still distinguished by incredible ecological indicators. They miraculously managed to avoid the harmful influence of civilization, for thousands and millions of years the water in them remains crystal clear. Some of the cleanest lakes and rivers on the planet are located in incredible hard-to-reach places to see them, tourists need to overcome a difficult path. Others, on the contrary, have long been centers of tourist life, which does not prevent them from preserving their unique environmental indicators. All the cleanest reservoirs of the planet are incredibly beautiful and, of course, deserve the attention of the most sophisticated travelers.
Crater Lake, USA
In the United States, on the territory of the state of Oregon, there is an incredibly beautiful Lake Crater, it was formed in the crater of an extinct volcano. This lake has become famous throughout the world for its unique deep blue water, which is considered one of the cleanest in the world. According to scientists, this lake was formed more than 7.5 thousand years ago, its average depth is about 350 meters. The dimensions of the lake are also very impressive, its length is about 9.6 km, and its width is about 8 km.
This lake is one of the deepest not only in the United States, but also in the territory North America... Several years ago, a national park, on the territory of which today interesting excursions...

In recent years, the amazing nature reserve has been visited by about 400,000 tourists from all over the world annually.
Crystal clear lake attracts not only curious travelers, but also ecologists and researchers. Several years ago, a group of scientists conducted an interesting experiment here. The fact is that initially there were no species of fish in Lake Crater, ecologists decided to add some species of trout and salmon here. Their experiment was completely successful, today the lake is inhabited by fish. Tourists are even allowed to fish here, subject to the only condition - they must use artificial bait.
Lake Zyuratkul, Russia 
In Russia among Ural mountains there is an amazing lake Zyuratkul, it is located at an altitude of 724 meters above sea level and is the most alpine lake Ural. The maximum depth of this lake is relatively small and is about 12 meters, and the area of the reservoir is 13.5 square meters. km. Today, the amazing lake is considered one of the cleanest in the world, despite the fact that the water in it is by no means transparent. It has an unclear tea hue, due to the fact that many streams flowing into the lake originate in swamps.
The area next to the lake is famous not only for its natural beauty, but also for its historical sites. During the study, scientists discovered several important archaeological sites, here they raised the tools of labor of primitive people and found a giant geoglyph. For local residents, Lake Zyuratkul has been a sacred landmark for hundreds of years; many interesting legends and beliefs are associated with it.
In the forests along the shores of the lake, hundreds of years ago Old Believers performed their rituals, while walking along them you can still see unusual monuments carved from wood. Within the territory of national park Zyuratkul has created excellent conditions for recreation. There are several equipped camping areas, so travelers can stay in these areas during the warmer months. scenic spots ah for a few days. Hundreds of different excursions are held here, during which you can see the most significant natural attractions, as well as unique historical areas.
Piccaninnie Ponds, Australia 
In Australia, on the territory of the Piccaninni Nature Reserve, there is a system of ponds of the same name, which have recently been considered a favorite resting place for divers. There are three ponds in the system, all of which are distinguished by crystal clear water. However, each of these ponds has its own unique features. "The first pond" is the smallest, its depth is only 10 meters. The Abyss pond is much deeper, its maximum depth is 100 meters. The water in this pond is crystal clear, the visibility in it can reach 40 meters.
The most unusual and interesting of the three ponds is "Cathedral", its depth is 35 meters. This pond was formed in a grotto of limestone formation and is most popular with divers. The system of ponds is located in a special swampy zone, which is remarkable not only for its water bodies, but also for its unique vegetation and fauna. This swampy area is home to several rare bird species, the observation of which attracts not only bird watchers, but also tourists.
The Piccaninni Park has many hiking trails for tourists, as well as some excellent viewing platforms from which you can admire the beautiful ponds and the landscapes surrounding them. Piccaninni National Park was formed in 1969, its area is about 8.6 square meters. km. Since a few years ago, the ponds were open to snorkelers and divers, today environmentalists monitor their cleanliness with particular care. Those who want to swim in these pristine ponds will need to follow some formalities.
Lake Masyuko, Japan 
In Japan, on the territory of the island of Hokkaido, there is another crystal clear lake - Masyuko. It is located in the Akan nature reserve, from all sides the lake is surrounded by incredibly beautiful mountains covered with dense vegetation. This crystal-clear lake was formed in the caldera of an active volcano; the water in it has a deep blue color due to its special mineral composition. Hundreds of tourists visit this beautiful lake every day as part of organized excursions in the national reserve.
While walking through the mountainous areas, they will have the opportunity to see many rare plants, animals and birds, the most interesting thing is to walk through these colorful places in the summer. However, visiting the reserve also has its own charms in winter. On the territory of the national park there is another crater lake - Kussyaro, which also has its own unique features. The thing is that several hot springs flow into it, which do not allow some areas of the lake to freeze even in winter. This feature attracts many heat-loving birds to the reservoir; whooper swans always winter here.
The main feature of Lake Masyuko is that not a single stream flows into it, and neither does it flow out. Researchers believe that it is precisely this feature of the lake that allows it to maintain its crystal clearness for hundreds of years. It is also worth noting that there are several interesting miniature villages on the territory of the reserve, where you can get acquainted with the life of local residents and buy interesting souvenirs.
Lake Bowman, USA 
In the United States, there is the amazing Bowman Lake, which is also known for its purest water. It is located in the state of Montana, in the territory national reserve Glacier. Despite the fact that the reserve is rich in a variety of natural attractions, it is still visited by a very small number of tourists. This largely contributes to the preservation of the unique ecosystem here. Lake Bowman is notable for its impressive scale, its length is about 11 km, and its width is about 1.5 km.
This fabulously beautiful lake is considered one of the most transparent in the world.Today, tourists are provided with all the conditions for organizing interesting rest... They can not only walk around the reserve, but also spend several days in a tent camp. The lake is home to a lot of fish, which tourists are allowed to catch, and in some areas of the lake you can swim.
The tent camp located on the shore of the lake is open only in the warm season and is well equipped. On its territory, toilets and even showers are equipped; here they take all measures to preserve the ecology of these places. Today, the main guests of this "resort" are local residents, although, in recent years, Bowman Lake has attracted a sufficient number of foreign travelers. It is not difficult to get to this wonderful lake; a road passes through the part of the reserve.
Lake Sheosar, Pakistan 
In the northern part of Pakistan, on the territory of the Deosai National Park, there is the fabulously beautiful Lake Sheosar. It gained popularity among tourists precisely because of its crystal clear water.For hundreds of years, this lake has remained one of the cleanest bodies of water on the planet. The maximum depth of this lake is 40 meters, its length reaches 2.3 km, and its width is 1.8 km. This lake is located in a very inaccessible mountainous area, at an altitude of 4,142 meters above sea level.
For travelers, both car and walking tours are organized. nature reserve... By jeep, you can get to the remote mountainous area in just a few hours, while the trek usually takes at least two days. For nature lovers, it is best to stroll through the reserve on foot; there are several specially designated areas on its territory where you can equip a tent camp.
The best time the period from the beginning of June to the end of September is considered for visiting the beautiful lake and walking in the reserve, at which time the plateaus surrounding the lake are covered with carpets of bright colors. One of the main inhabitants of these picturesque places are butterflies, there are several dozen species of them here. Already in November, the beautiful valley and the lake are hidden under its thickness by snow, it completely melts only by May. There are no excursions around the reserve during the cold season.
Lake Peyto, Canada 
In Canada, one of the cleanest lakes is worth looking for in the Banff National Park, here is the world famous Peyto Lake. This lake is located in an incredibly beautiful foothill area, its area is about 5.3 square meters. km. The lake stretches for 2.8 km in length, and its average width is only 800 meters. The first to discover this amazing lake was the traveler Bill Peyto, in honor of his discoverer the lake got its name.
One of the main features of the lake is its unusual shape, if you look at it from a bird's eye view, it resembles a huge wolf head. The lake water has a rich turquoise hue, which also attracts attention. Every year the lake is replenished with water from nearby glaciers. Mountain streams bring the smallest particles of minerals into the lake, which make the color of the water so unusual.

Lake Baikal, Russia 
On South Eastern Siberia there is a world famous landmark - Lake Baikal. It is the world's largest freshwater reservoir and the most deep lake on the planet, its maximum depth is 1,642 meters. The lake area is 31.7 sq. km. The lake is interesting not only in itself, it is surrounded by unique natural landscapes. Many unique endemic animals live here, and you can also see a lot of rare plants.
Lake Baikal has tectonic origin The water is considered one of the cleanest in the world and is home to valuable species of fish. One of the main features of the water is its high oxygen content, while the amount of minerals is very small. Lake Baikal is also one of the coldest in the world, the water temperature in it, even in the summer months, does not rise above +8 degrees Celsius.
One of the main unresolved issues related to the lake is the theory of its origin. According to scientists, its formation was provoked by tectonic activity, the age of the lake is at least 25 million years. The inhabitants of the lake are of great interest to researchers; there are more than 2,600 species of them. More than half of the aquatic inhabitants are endemic and cannot be found in any other body of water in the world. Wastewater is one of the most important environmental problems of Lake Baikal. Many rivers flow into the lake, the water in some of them is polluted with industrial waste.
Moraine Lake, Canada 
In Canada, there is the famous Moraine glacial lake, it is located in the Banff National Park. This lake is quite small, its area is only 500 square meters. meters, and the maximum depth reaches 14 meters. At the same time, the beauty of this lake is difficult to find equal. The discoverer of this unique natural landmark was the explorer Walter Wilcox. When he discovered this lake, then uninterruptedly admire it for half an hour. Later, in his manuscripts, the scientist noted that these were the happiest half an hour in his life.
This lake is located in a very inaccessible mountainous area, therefore long time no one knew about its existence. The water in the lake, which fills it from year to year during the melting of glaciers, has a rich sapphire hue. Against the background of the surrounding mountain ranges, the lake looks fantastic. The best time to visit the lake is considered to be June, this time is the peak of melting of glaciers, the lake reaches its maximum size.
Travelers can visit Lake Moraine only from May to September, the rest of the year the mountain road is closed for safety reasons. You can easily get to the lake by car, the closest large locality is the city of Calgary. In recent years, organized excursions have been carried out to the lake, tourist route a bus runs. Half an hour drive from the lake there is a small mountain village, which will also be very interesting to visit as part of the excursion.
Jenny Lake, USA 
Lake Jenny is located in the northwestern part of Wyoming; today it is part of the Grand Triton National Park. This lake is also of glacial origin, it is located at an altitude of more than 2,000 meters above sea level. According to researchers, the lake was formed about 12,000 years ago, its maximum depth reaches 129 meters, and the area is about 482 square meters. km. Despite the fact that this lake is one of the cleanest in the world, motor boats are allowed on it, which is actively used not only by researchers, but also by tourists.
The main route, formed along the shores of the lake, is called Jenny Lake Trail; excursions here are conducted not only during the day, but also at night. Nearby is the beautiful Cascade Canyon, which is also an important attraction of these places. The name of the lake has a very interesting story... In 1872, one of the first large expeditionary groups worked on the lake, led by the Englishman Richard Lee. This beautiful lake was later named after his wife Jenny.
Another attractive feature of the reservoir is the variety of fish species; fishing was allowed here a few years ago. Trout is the most cherished catch of fishermen; in order to go fishing here, you need to obtain a special license. Tourists are allowed to travel to these places only when accompanied by guides; there are many predatory animals among the inhabitants of the nearby forests, and bears are also found here. Like many years ago, today the national park attracts hunters, and climbers also like to rest here.
Lake Pukaki, New Zealand 
There are many wonderful lakes in New Zealand too, noteworthy tourists. One of them is worth looking for on the Yuzhny Island, here is the beautiful Lake Pukaki. This glacial lake has become known all over the world due to the rich blue color of the water, which, among other things, is also incredibly clear. The lake area is 178.7 sq. km, it is located at an altitude of more than 500 meters above sea level. This fabulously beautiful body of water is 15 km long and about 8 km wide.
Several years ago, Lake Pukaki became part of a large hydropower system; experts made sure that such use of the reservoir did not in any way affect its environmental performance. For local residents, the emergence of a hydrotechnical unit was a real breakthrough, it was thanks to the lake that they finally received stable electricity.
Not everyone knows that initially the glacial lake was very small, its maximum depth was no more than 25 meters. When in the 40s of the last century they began to build a hydrotechnical station, the volume of the lake was significantly increased. Initially, a small island was located in the center of the lake, which was flooded as a result of the expansion of the reservoir. Water in glacial lake always very cold, so take a dip in its crystal clear azure water not everyone dares. Even at the height of summer, its temperature is no more than + 7 degrees Celsius. Local residents have many beautiful legends associated with the lake; it got its name in honor of one of the mythical warriors.
Lake Tahoe, USA 
In California, there is an amazing freshwater Lake Tahoe, it is located in the picturesque foothill region of the Sierra Nevada. This lake is well known to tourists; in the immediate vicinity there are several popular ski resorts... Lake Tahoe is the second deepest lake in the United States, with an average depth of 305 meters and an area of about 495 square kilometers. km. Of the most beautiful lakes in the world, Tahoe is considered one of the most easily accessible; large highways run along the entire perimeter of the reservoir.
A lake was formed at the site of a geological fault in the earth's crust about 3 million years ago. Today, not only the lake itself with fantastic sky-colored water is of great interest, but also the coniferous forests surrounding it. Here you can see many rare species of pine and fir, as well as rare species of shrubs and grasses. The lake was discovered relatively recently, in 1844, its discoverer is Lieutenant John Fremont.
He explored these mountainous regions in search of a river, and discovered an incredibly beautiful lake, which scientists from all over the world were exploring in a few years. Most tourists began to visit these places after 1960, when the Winter Olympic Games were held at one of the local resorts. Since then, an excellent tourist infrastructure has remained here, today there are comfortable hotels near the lake, and there are also many ski slopes of various levels of difficulty. It will be interesting for amateurs to relax here. hiking, at any time of the year, fascinating excursions are held near the lake.
Blue Lake, New Zealand 
One of the cleanest and most unusual lakes on the planet with a complex name Rotomairewhenua is located in New Zealand, translated from the Maori language its name means "Blue Lake". This miniature freshwater lake is located in the Nelson National Reserve, it is part of a complex system of lakes. Ecologists began to study the reservoir in detail only since 2011, they accidentally discovered that the water in the lake is extremely clean.
The visibility in it can reach 80 meters. From year to year, the lake is fed by water from nearby glaciers. Flowing with mountain peaks, it passes through many natural rocks that act as a natural filter. Largely due to its purity, the water in the lake has an amazing hue, which varies from deep blue to light purple during the day.
One of the first experts to take an interest in the lake was the hydrologist Rob Mirriles. Having admired the crystal clear water, travelers should definitely take a walk through the surrounding forests and mountain ranges... There are no tourist bases, it is extremely rare to meet travelers here. The main visitors to these scenic spots are researchers and ecologists, not so long ago as a result of a major study of the water in Blue lake they were equated in properties and quality to distilled water.
Petermann River, Greenland 
Some rivers are amazingly clear. An excellent example is the Petermann River, located in Greenland; it is known to a wide range of travelers under the unofficial name of the Blue River. The location of the river is the glacier of the same name, which melts in the summer and forms many small streams. They all converge into a single river, the water in which has a rich blue hue.
The incredibly beautiful and clean river poses a huge threat to the global ecology. In recent years, the Petermann Glacier has begun to melt four times faster, which contributes to a significant increase in the water level of the world's oceans. According to the forecasts of researchers, in the coming years the glacier will melt even more intensively, which could lead to serious environmental disasters. In the meantime, the crystal clear river is of great interest to scientists. They can estimate the composition of glacial waters that have been frozen for millions of years.
It is very difficult for ordinary travelers to get to this remote corner of the world with an incredibly harsh climate; this can only be done together with organized expedition groups. Now ecologists are trying to take all possible measures to minimize the influx of glacier melt water into the world ocean. In the coming years, he may lose up to 100 sq. kilometers of ice, so much melt water would be enough to provide a large metropolis for 10 years.
Weddell Sea, Antarctica 
Off the coast of West Antarctica lies the beautiful Weddell Lake, which is also one of the cleanest bodies of water on the planet. It bears its name in honor of the discoverer J. Weddell, who made an expedition to these places in 1832. The sea area is 2,900,000 sq. km, and its maximum depth reaches 6 800 meters. In addition to the incredibly beautiful water of a heavenly shade, the sea is distinguished by a huge number of ice floes that float in it all year round.
This beautiful clear sea has become home to thousands of aquatic inhabitants, huge populations of whales, seals and fish live here, and penguins are also typical inhabitants of these places. Today the Weddell Sea is considered the cleanest in the world. The last major study of its water took place in 1986, the average visibility was estimated at 79 meters, which corresponds to that of distilled water.
Not all research groups decide to swim in this sea, not to mention ordinary tourists; drifting ice poses a huge threat to ships. Many natural and physical phenomena are associated with the North Sea. The water in it never freezes, despite the fact that its temperature can reach -25 degrees Celsius. The Weddell Sea is the coldest and cleanest sea on the planet. To see it with their own eyes, travelers need to be part of one of the research expeditions, but they rarely go to this harsh sea.
Almost every geographical name has a history of origin. It has long been no secret why the Red Sea was called the Red Sea. It is known from school that this body of water is the saltiest (not counting dead sea), not a single river flows into it. This sea is the youngest of its kind, it has no equal in beauty and diversity of the underwater world.
The sea is famous for its coral reefs, most of which are bright red. Since the water is crystal clear, it looks red from a bird's eye view. There is also a version about large accumulations of algae or fish, which give the water a corresponding red tint.
2. The color of the rocks.
The sailors of antiquity were delighted with the unusual red rocks reflected in the sea water, so they christened it Red. Why the hills were of this color, whether from the setting sun, or from the rock, history is silent.
3. The color of the blood.
According to the Bible, Moses led his people through the parting waters of the Red Sea. When the foot of the last Jew stepped on land, the sea came together, burying the bodies of the pursuers. In that place, the water turned red from their blood, and therefore they began to call the sea space Red.
4. Misinterpretation of the ancient name.
Arabs found letters ancient people- Himyarites, who lived on the coast of the sea until the 6th century. Their writing did not display short vowels, so the name of the sea, consisting of three consonant letters "x", "m", "r" was interpreted as "Ahmar", which means "red" in Arabic.
5. Translator's mistake.
According to the Bible, Moses with his people passed through the "reed sea", translating it into English looks like "reed sea". There is an assumption that there was an error, one letter was lost, and "reed" turned into "red sea" - "Red".
6. Geographical location.
According to the ancient Assyrian calendar, the cardinal points were associated with certain colors. For example, red symbolized south, black - north, green - east, white - west. So it turned out that the sea located in the south began to be called Red.
7. Color of foreign bodies.
According to one version, it could be numerous petals of red flowers, according to another - red ground pepper. But scientists put forward a third, associated with a large number of marine life of the corresponding color.
Red Ocean Slice Love Stories
But how they could get into the water, explain several very real stories.
Story 1. Love is red
Oddly enough, each person associates love with different colors: from white to black with the most unusual shades and blotches, maybe even striped. In Feng Shui, this feeling is green. But one person proved that his love is bright red, like pink petals, and huge, like the sea.
It happened a very long time ago, even before our era, so the names of the heroes of history, unfortunately, have not reached the present day. Then a young guy lived on the coast of the sea, he could not boast of beauty and strength. But he was gifted with a big kind heart and a sharp mind.
The guy was from a poor family, worked from morning to evening, tirelessly. It so happened that at one of the holidays, where all the inhabitants of the city gather, he saw a beautiful girl, from whom he could not take his eyes off. Subsequently, the young man found out that she was the daughter of one of the most respected people in the city. And the saddest thing is that preparations were underway for the wedding, which was to take place in a few weeks.
The lover tried to throw the girl out of his head and heart, but he could not help himself. Every minute her waist in a red cape rose up in front of him, her blue, almost transparent eyes, looked into the very soul. Her hair the color of sand, wavy like dunes at the bottom of the sea, did not allow her to breathe calmly.
Realizing that the chances of winning the girl's heart are very small, the guy decided on a desperate step. He began to ponder the seemingly almost unrealistic plan to conquer a woman's heart.
The girl went out to the balcony of her house every morning to admire the sunrise, which illuminated the clear water with bright rays. The sight she saw one morning struck a young soul.
The entire surface of the sea, which was in the field of view, turned from transparent blue to bright red. To find out what happened, the girl went down to the sea. On the shore I saw a man in a boat who did not take his eyes off her. What happened to the water, why did its color change? It turns out that the entire surface was strewn with scarlet rose petals.
The girl, fascinated by what she saw, without hesitation got into the boat, the bottom of which was covered with pink petals, only white, and looked at the young man in surprise. The words that the guy said during the boat trip have forever remained in the girl's heart. She fell in love with him at first sight and realized that she would not be happy without him. So no one else saw them. And the rose petals swayed for a long time on the sea waves, which is why the locals called it Red.
Story 2. The peppery sea
In ancient times, a merchant lived in the city on the shore of a warm reservoir. He made his fortune by trading in spices, especially paprika. Often a person left his home, spending time on the ship because of his profession.
The merchant lived half his life, but he never started a family. They did not like him in the city for his greed and anger. The whole house was stuffed with gold, jewelry and bags of spices. The merchant did not participate in the life of the city, did not help the poor, and was cruel to the defenseless.
The people decided to expel him by a general meeting. They were allowed to take all the goods and sail to other shores. Out of greed, the merchant so loaded his ship that, not having time to hide behind the horizon, the ship sank. A few hours later, the sea turned scarlet from a huge amount of pepper scattered.
It is interesting:
The gates of cities in Ancient China had different colors, depending on which side of the world they went to. Also, the tips of the arrows in the modern compass have the corresponding colors: red, black, green and white, respectively denoting the parts of the world: south, north, east and west.
In the first "documents" dating from the second century BC, the Red Sea could be referred to as Eritrean (Eritrea is a state on the shores of the Red Sea from the East of Africa), and in the 16th century it was called Suez.
If you break off a branch of a bright coral, then after a few minutes without water it will lose its attractiveness and become off-white or brown. Therefore, tourists cannot get a trophy in the form of red corals, and only a photo of it can preserve such beauty for demonstration to family and friends.
This sea is recognized as the cleanest. Most likely, due to the fact that rivers do not flow into it. As a rule, it is they who apply sand, silt and other water polluting particles with the current.
The water here is the saltiest. Firstly, rivers do not enter the sea, that is, there is no inflow of fresh water, and secondly, high temperatures of water and air contribute to intensive evaporation of water, which further increases the concentration of salts. Today it is 41 g per liter of water, in the Black Sea it is only 8 g.
The Red Sea is gradually increasing in size. It is located in a seismic zone where the plates move without stopping. Therefore, the banks diverge, the displacement reaches up to 1 cm per year, which means that over a century the border will expand by 1 m.
History keeps many mysteries and unusual events. That is why the White Sea is called that way, so far no definite answer has been received. Often, the origin of geographical names has several versions, which are supplemented by modern interpretations. It is often difficult to grasp the line between fiction and reality.
