A unique phenomenon occurs periodically - this is when the Black Sea freezes. It can be seen in different parts of the world, but most often in the northern regions. There was a time when this sea froze completely. As far back as the fifth century, Herodotus wrote that the best way to escape from the heat was in the Crimea, where there was extreme cold for many months. In this place everything freezes, including the sea. It was possible to cross the ice from one coast to another - there is evidence that when the Black Sea froze over, it was possible to cross it from Bulgaria to the Crimea. A similar phenomenon still occurs, but in separate corners. Events like this quickly get on the Internet, and people come to those countries where the sea freezes over to admire the unusual natural phenomenon.
Eh, sea, sea…
The Black Sea refers to the inland waters of the Atlantic Ocean. It connects with the Bosporus of Marble, and through the Dardanelles - with the Aegean and Mediterranean Seas. The Kerch Strait connects with the Sea of Azov. From the north, the Crimean peninsula cuts deep into the sea. The shape of the sea resembles an elongated oval.
A characteristic feature for a reservoir is the absence of life at a depth of more than 150 meters. This is due to the saturation of the lower layers with hydrogen sulfide. As a result, when freezing, ice of high density is formed.
A bit of history
In history, there is information about when the Black Sea froze. So, in 860 it was completely covered with a thick layer of ice. In those years, it was possible to get from one part of the reservoir to another, the same thing happened in 1010.
Does the Black Sea freeze in the south? Yes, it freezes. Back in 1010-1011. the sea was covered with ice off the coast of Turkey, as well as near the lower reaches of the Nile. And after 610 years, it again completely disappeared under the ice.
Ice on the sea in the 20th century
There is information when the Black Sea froze in the south. So, in 1953, the reservoir was covered with ice off the coast of Crimea. That year, severe frosts completely hid the Sea of \u200b\u200bAzov under the ice. There are references to such anomalies in ancient scriptures that have survived to this day.
Freezing in the 21st century
In 2012, in the regions of Crimea, Romania, Bulgaria, Odessa, everything froze. In these areas, all maritime traffic was suspended until 15 February. That year, the thickness of the ice cover reached forty centimeters.
Coastal residents were not afraid of this natural phenomenon and began to skate on frozen sea ice, because thisthe phenomenon does not happen often.
Ice cover
And when does the Black Sea freeze, every winter? This phenomenon usually occurs during severe winters. Near the Caucasian and Anatolian coasts, ice rarely appears. The Dniester and Dnieper-Bug estuaries freeze almost every year.
Near Crimea, ice forms up to Cape Tarkhankut, and broken ice often reaches Evpatoria. Near the Kerch Strait there are ice brought from the Sea of Azov. They can move towards Anapa or Feodosiya.
Coast of Bulgaria
In 2017, for the first time in many years, the sea froze off the coast of Bulgaria. The last time this phenomenon was recorded in 1954, when the ice bound the port of Burgas, creating unusual ice sculptures from the ships that were in the port at that moment. They stood motionless for a long time, waiting for the "defrost".
During its century-long history, the reservoir froze several times - in 1929, 1942 and 1954. The same anomalous phenomenon occurred in 2017. The Danube almost completely sank under the ice, which completely stopped shipping.
Photos of the frozen Black Sea quickly spread around the Internet, because this phenomenon is extremely rare. People from other parts of the world flocked to the country to see this unusual event with their own eyes.
Interesting facts
For long millennia, the reservoir periodically froze. Scientists know in what year the Black Sea froze according to scriptures and observations. By their reckoning, it's covered in iceabout once every 78 years.
According to scientists' forecasts, sea levels will rise by one and a half to two meters in our century. As a result of changing the coastline, in 50 years, many beaches will go under water.
Sea water is a natural solution of various s alts. They affect the freezing point of water. So, if the salinity of the water is 3.5%, then already at -2 degrees it will begin to be covered with ice. This process causes the water mass to condense.
The frozen Black Sea is a beautiful sight. The ice looks like the waves splashed. The pier, the ships, the coastline - everything is covered in ice. All water smudges freeze, creating incredible patterns, sculptures.
