Summer Holidays on the Black Sea

The Black Sea is a wonderful summer vacation that combines the gentle southern sun, warm sea water, excellent beaches and everything you need to have a good vacation, relax and travel. The air on the Black Sea coast is very clean, air currents from the sea and from the adjacent steppes mix here, creating a mixture that is beneficial for the body. The Black Sea coast of Ukraine, from the Crimea to Odessa, is indented by a large number of estuaries, rich in fish, the beaches of the Black Sea coast here are sandy, with a flat bottom, unlike the beaches of the Crimea and the Caucasus. A large number of vegetables and fruits at fairly low prices amazes tourists and vacationers, and a huge number of local attractions, natural monuments, historical sites, cities on the Black Sea - Odessa, Skadovsk, Ochakov, Koblevo and many others, always attract those who want to relax on the Black Sea.

History of the Black Sea

It is believed that on the site of the current Caspian, Mediterranean, Aral, Black and Azov Sea, there was one of the bays of the ancient Tetis Ocean. In the process of evolution, this bay was divided, and, about a million years ago, after the appearance of the ridges of the Crimean and Caucasian mountains, the Black Sea separated from the oceans and became a separate, almost fresh lake. This situation persisted for a long time, and only about eight thousand years ago, as a result of a strong earthquake, the Bosphorus Strait was formed, through which the waters of the Mediterranean Sea began to flow into a fresh lake, and as a result, the modern Black Sea was formed.

The Geographical Position of the Black Sea

The Black Sea is located inside the Eurasian continent, the area of the Black Sea is more than four hundred thousand square kilometers, the total length of the coastline is about four and a half thousand kilometers. About three hundred different rivers flow into the Black Sea, among them the largest are the Dniester, the Southern Bug, the Dnieper and the Danube. The Black Sea through the Kerch Strait is connected with the Azov Sea, and through the Bosporus Strait - with the Sea of Marmara. The water in the Black Sea is extremely transparent - visibility is maintained even at a depth of more than twenty meters.

Features of the Black Sea

The main feature of the Black Sea is its division in depth into two completely different zones - one of them extends to a depth of about two hundred meters, in which the oxygen content is normal for the seas, and the other part, deeper than two hundred meters, is completely devoid of oxygen and saturated with hydrogen sulfide, and at the same time occupies about nine-tenths of the total volume of water in the Black Sea. In the depths of the Black Sea, the entire mass of water is in a stagnant state, there is no oxygen, living beings and algae, only microspira bacteria live. As a result of the vital activity of these bacteria, hydrogen sulfide is released, which accumulates at the bottom of the Black Sea. Over the past millennia, bacteria have accumulated more than a billion tons of hydrogen sulfide in the Black Sea, which is extremely toxic, moreover, combustible and its mixture with air is explosive, but, fortunately, the concentration of hydrogen sulfide in the waters of the Black Sea is insignificant and therefore safe.

Inhabitants of the Black Sea

Due to the saturation of the lower layers of the sea with hydrogen sulfide, only a little more than one tenth of the volume of the Black Sea water is inhabited by flora and fauna - more than two hundred and fifty species of algae and about two thousand living organisms live in the Black Sea. The water of the Black Sea contains approximately two times less salt than the waters of the World Ocean, this is due to the large inflow of fresh water coming from the full-flowing rivers flowing into the Black Sea, as well as the inflow of water from the Sea of Azov, which is even fresher than the Black Sea.
