At the moment, the water of the Black Sea is very cold for swimming and is suitable only to wet your feet, but weather stations report warming water in 5 days.
In the yard on July 8 - the height summer season, and the Black Sea is not available for swimming. Forecasters predict warming only after July 12. Although the Sea of \u200b\u200bAzov pleases with its warm water.
Now there are a lot of tourists in the resorts of Russia, and everyone goes for only one luxury in the height of summer - overseas. But alas, luck is not on their side, because for now tourists can only enjoy its view, or daredevils can get their feet wet. The temperature of the Black Sea is now too low to swim in it. Moreover, such a temperature will last another five days, and only after July 12 will it begin to rise gradually.
So at the moment the resorts in Sochi, Tuapse and Novorossiysk are not relevant.
For the last 3 days in Sochi, the sea temperature has been around +13 ° C, in Tuapse + 17 ° C, in Novorossiysk + 20 ° C.
The Black Sea opens its arms only in Anapa and Gelendzhik, as there the water temperature is +24°C and +26°C, respectively.
Moreover, in Sochi and Tuapse one can observe "upwelling" - a natural phenomenon when the wind draws warm water. Instead of warm water, deep, cold waters come. And in the Black Sea, the temperature difference on the surface and in the lean water can reach +14 ° С ... + 16 ° С. In this case, the wind pulled the warm water away from the coast and pushed out the cold deep water. That is why the sea temperature is very low now.
Meteorologists and weather forecasters say that when the wind changes direction and blows not from the coast, but from the sea, then tourists in Sochi will be able to enjoy pleasantly cool, not icy water.
The situation can change only after July 12. Therefore, if you choose a place to stay at the moment, it is best to go to Anapa or to Sea of Azov, because there these days it will be warm both on the sand and in the sea.
The Sea of Azov emerges from the shadow of the Black Sea
Sometimes tourists forget that Krasnodar Territory there is not only the Black Sea. The shores of the southern region are also washed by the Azov. Now it is warm - + 25 ° С ... + 26 ° С. It is because of the cold waters of the Black Sea that the Sea of \u200b\u200bAzov is becoming more relevant for this period.
Moreover, meteorologists say that there is no such natural phenomenon as upwelling in the Sea of Azov. All this is due to the fact that the Sea of \u200b\u200bAzov is shallow and the water in it warms up evenly throughout the depth. The temperature of all water can fluctuate up to a maximum of 5 ° C. If a storm passes, then both the surface and the bottom will be almost the same temperature.
Man is an integral part of nature. She can be favorable, friendly to us. We drink water, breathe air, get heat and food from the environment. This is the source of our life.
But our planet can not only give its wealth to people, but also bring destruction, misfortune and deprivation. Earthquakes, fires and floods, tornadoes and volcanic eruptions claim the lives of many people. Hydrogen sulfide in the Black Sea can become a natural disaster. There are a lot of them in these waters.
The proximity to the Black Sea can cause tragedy for many people. What are the options for the development of events, as well as how to avoid them, scientists find out. It is interesting to know about their opinion to every inhabitant of our country and the whole world.
What is hydrogen sulfide?
Without going into chemical formulas, we should consider what properties hydrogen sulfide has. It is a colorless gas, which is characterized by stable and hydrogen. It is destroyed only at temperatures above 500 ºС.
It is poisonous to all living organisms. Only a few types of bacteria survive in this environment. The gas is known for its peculiar smell of rotten eggs. There is no flora and fauna in the water in which hydrogen sulfide is dissolved. The waters of the Black Sea contain it in huge quantities. The hydrogen sulfide zone is simply impressively huge.
It was discovered back in 1890 by N.I. Andrusov. True, in those days it was not yet known exactly in what quantities it was contained in these waters. The researchers lowered metal objects to different depths. In hydrogen sulfide water, the indicators are covered with a black sulfide layer. Therefore, there is an assumption that this sea got its name precisely because of this feature of its waters.
Features of the Black Sea
Some people have a question: where does hydrogen sulfide come from in the Black Sea? But it should be noted that this is not an exclusive feature of the presented reservoir. Researchers find this gas in many seas and lakes around the world. It accumulates in natural layers due to the absence of oxygen at great depths.
Organic remains, sinking to the bottom, do not oxidize, but rot. This contributes to the formation of poisonous gas. In the Black Sea, it is dissolved in 90% of the water mass. Moreover, the layer of occurrence is uneven. Near the coast, it begins at a depth of 300 m, and in the center it is already found at a level of 100 m. But in some areas of the Black Sea, the layer of clear water is even less.
There is another theory of the origin of hydrogen sulfide. Some scientists claim that it is formed due to the tectonic activity of volcanoes active at the bottom. But there are still more adherents of the biological theory.
Movement of water masses
In the process of mixing, hydrogen sulfide is processed and changes its form in the Black Sea. The reasons why it nevertheless accumulates are the different levels of salinity in the water. The layers mix very little, since the sea does not have sufficient communication with the ocean.
Only two narrow straits contribute to the process of water exchange. The Bosphorus Strait connects the Black Sea with the Sea of Marmara, and the Dardanelles with the Mediterranean. The closure of the reservoir leads to the fact that the Black Sea has a salinity of only 16-18 ppm. Oceanic masses are characterized by this indicator at the level of 34-38 ppm.
The Sea of Marmara acts as an intermediary between these two systems. Its salinity is 26 ppm. The water of Marmara enters the Black Sea and sinks to the bottom (since it is heavier). The difference in temperature, density and salinity of the layers leads to the fact that they mix very slowly. Therefore, hydrogen sulfide accumulates in the natural masses.
Ecological catastrophy
Hydrogen sulfide in the Black Sea has become the subject of close attention of scientists for a number of reasons. The ecological situation here has deteriorated significantly in recent decades. Mass discharges of waste of various origins led to the death of many species of algae and plankton. They began to sink to the bottom faster. Also, scientists found that in 2003 a colony of red algae was completely destroyed. This representative of the flora produced about 2 million cubic meters. m of oxygen per year. This curbed the growth of hydrogen sulfide.
Now the main competitor of poisonous gas simply does not exist. Therefore, environmentalists are worried about the current situation. So far, it does not threaten our safety, but over time, a gas bubble may come to the surface.
When hydrogen sulfide comes into contact with air, an explosion occurs. It destroys all living things in the radius of destruction. No ecosystem can withstand human activity. This brings a possible catastrophe closer.
Explosion at sea
Sad incidents are known in history when the waters of the sea blazed with fire. The first recorded case occurred in 1927, 25 kilometers from Yalta. At this time, the city was destroyed by a powerful earthquake of eight points.
But it was also remembered by the affected residents by a terrible fire that engulfed the expanses of water. People then had no idea why the Black Sea was burning. Hydrogen sulfide, the explosion of which was caused by tectonic activity, came to the surface. But such incidents can happen again.
Hydrogen sulfide, coming to the surface, comes into contact with air. This results in an explosion. It can destroy entire cities.
The first factor of a possible explosion
An explosion that can take the lives of thousands, millions of people and all living organisms in the affected area can occur with a high degree of probability. And that's why. In the Black Sea, hydrogen sulfide is not processed, accumulating under the ever-decreasing thickness of clean water. Humanity treats this problem irresponsibly. Instead of using technology to process poisonous gas, we dump waste into the water. The decay process is getting worse.
Telephone, oil and gas pipelines run along the bottom of the Black Sea. They are damaged, fires occur. This may cause an explosion. Therefore, human activity can be considered the first factor in a possible catastrophe.
The second cause of the explosion
Natural disasters can also trigger an explosion. Tectonic activity in the area is not uncommon. Hydrogen sulfide at the bottom of the Black Sea can be disturbed by an earthquake or volcanic eruptions. Scientists argue that if the same disaster occurred today as in September 1927, the explosion would be so strong that a huge number of people would die. Further, a huge amount of sulfur would have fallen into the atmosphere. would do a lot of harm.
The thin layer of pure water is getting smaller. Hydrogen sulfide comes especially close to the surface in the southeast of the Black Sea. With rocks in this area, a terrible catastrophe is possible. But today, an explosion is possible in any area.
The third cause of the disaster
Thinning of the clean layer sea water can lead to a spontaneous release of a bubble of poisonous gas from the bowels. Why there is so much hydrogen sulfide in the Black Sea is not surprising. The main factors of environmental degradation were considered earlier.
Scientists say that if all the hydrogen sulfide resting on the bottom rises to the surface, the explosion will be comparable to the impact of an asteroid the size of half the moon. This would change the face of our planet forever.
In some areas, it approaches the surface at a distance of 15 m. Scientists say that at this level, hydrogen sulfide disappears on its own during autumn storms. But this trend is still alarming. As time goes by, the situation, unfortunately, only worsens. From time to time, a huge amount of dead fish washed up to the shores, caught in a hydrogen sulfide cloud. Plankton and algae also die. This is a formidable warning to mankind of an impending catastrophe.
Similar disasters
Toxic gas is found in many bodies of water around the world. This is far from a unique phenomenon that characterizes the bottom of the Black Sea. Hydrogen sulfide has already shown its destructive power to people. From history you can learn about such misfortunes.
For example, in Cameroon, in a village on the shores of Lake Nyos, the entire population died due to gas rising to the surface. The people who were caught by the disaster were found after a while by the guests of the village. This misfortune claimed the lives of 1,746 people in 1986.
Six years earlier, in Peru, fishermen going out to sea returned empty-handed. Their ships were black due to the oxide film. People were starving as a large population of fish died.
In 1983, for unknown reasons, water Dead Sea darkened. It seemed to be turned over, and hydrogen sulfide from the bottom rose to the surface. If such a process took place in the Black Sea, all life in the surrounding areas would die as a result of an explosion or poisoning with poisonous fumes.
The real situation today
In the Black Sea, hydrogen sulfide constantly makes itself felt. Upwellings (updrafts) lift gases to the surface. They are not uncommon in the Crimean, Caucasian regions. Near Odessa, there are frequent cases of mass death of fish that fell into a hydrogen sulfide cloud.
Very when such emissions occur in a thunderstorm. Lightning caught in a large hearth provokes a fire. The smell of rotten eggs that people feel indicates that the permissible concentration of a toxic substance in the air has been exceeded.
This can lead to poisoning and even death. Therefore, the deterioration of the ecological situation should be noticed by us. It is necessary to take measures to reduce the concentration of hydrogen sulfide in the waters of the Black Sea.
Ways to solve the problem
Specialists are developing several methods to eliminate hydrogen sulfide in the Black Sea. A group of Kherson scientists proposes to use gas as a fuel. To do this, lower the pipe to the depth and once raise the water to the surface. It will be like opening a bottle of champagne. Sea water, mixing with gas, will seethe. Hydrogen sulfide will be extracted from this stream and used for economic purposes. When burned, the gas releases a large amount of heat.
Another idea is to carry out aeration. To do this, deep-passing pipes are pumped fresh water. It has a lower density and will contribute to the mixing of marine layers. This method has been successfully used in aquariums. When using water from wells in private homes, it is sometimes necessary to purify it from hydrogen sulfide. In this case, aeration is also successfully applied.
Which way to choose is not so important. The main thing is to work on solving the environmental problem. In the Black Sea, hydrogen sulfide can be used for the benefit of mankind. The problem cannot be ignored. Complexity in its decision will be the most reasonable action. If the right steps are not taken now, a big disaster can happen over time. It is in our power to prevent it and save ourselves and other living organisms from death.
Gelendzhik is resort town, however, in given time resting there is impossible. All due to the fact that sewage was discharged into the Black Sea.
Now there is a terrible smell on the beaches, in some places the water has turned brown. Despite this, many tourists continue to visit the beaches every day, hoping that the situation is about to change.
As early as the ninth of July this year, the beaches were closed. Law enforcement officials did not explain anything, but simply kicked people out of the beach, after which they blocked the entire coastline using special tapes. All this time, the police watched to ensure that none of the people went into the sea.
After some time, the situation became clearer. There was information that experts are waiting for the results of the study of water. So, the management decided to play it safe. If tourists or local residents get poisoned or get sick with something, the city administration will not laugh.
And at this time, there is no limit to the indignation of tourists, because holidays in Gelendzhik are not so cheap and profitable, and many arrived for only a few days, so the vacation was completely ruined.
At present, people do not know what to do, because all the tickets were bought in advance, and no one knew that this could happen. And what can be done seaside resort how not to swim and sunbathe? And if the beaches are closed, you can not go at all.
The situation is promised to be resolved in the future tense, but tourists do not get better from this. Many flew to the resort not for long.
There is a lot of controversy on this topic right now. Outraged tourists point out that they did not spend so much money on vacations to swim in waste and enjoy fetid odors.
And at this moment, local media say that there was an accident at the water utility. There was a break in the sewer system, due to which the water in some places on the sea turned brown. In other words, feces float in the Black Sea, and even in too in large numbers.
The specialists of the enterprise tried to quickly correct the situation, pump out water, but nothing happened. At present, it remains only to wait for the water in the Black Sea to renew itself.
Some brave tourists try to find less polluted places so that they can still swim, but the guards chase them back behind the fence. And this is not because of the color of the water, because the sea can contain dangerous bacteria and diseases. This situation will continue until all test results are ready.
Note that initially the ban on swimming was explained by the fact that the water in the sea is too icy. But after some time it became impossible to deny something. It turned out that there was an accident at the water utility, so human feces floated into the sea.
The local government said that now they are trying to solve the problem with all their might. In the meantime, tourists are offered to visit other beaches that are located in the suburbs or in the direction of Novorossiysk.
It should be noted that since the beginning of this month, in all regions of the Black Sea coast, a very low temperature water. So, on the eighth day of the current month, the water in Anapa and Novorossiysk became very cold.
The management of Anapa introduced a ban on swimming, and earlier only children were not allowed to swim here. Black balloons were hung on the beaches, and the necessary message was broadcast all the time on local communications.
On July 10, the water began to warm slightly, so officials decided to lift the ban on swimming, although the ban on children was still in effect until Wednesday. Two days earlier, there had been a terrible incident in Anapa. In the High Bank area, a child almost died. An eleven-year-old girl was sent to a Krasnodar clinic in a coma.
Earlier it became clear that the government of Gelendzhik also banned swimming, but here the situation is completely different. Recently, a sewer burst here, due to which feces floated in large quantities in the sea.
July is in full swing, along with it the sea resort swimming season. So you want to dip your body, heated by a 30-degree heat, into sea foam jets and experience blissful joy. But it wasn’t there .... People who came thousands of miles from their places on the sea to complain about the cool water, the lack of enjoyment from swimming and are forced to lie on the beaches “dry”.
In addition, there was talk on the Web that the water had changed color and acquired a turquoise hue. What is the reason for these phenomena? Let's start with the cold.
Why is the water in the Black Sea cold in summer
Well, in fact, why in mid-July, doctors and the Ministry of Emergency Situations in Anapa give recommendations on limiting swimming for organized groups children due to the low temperature of the water in the sea. And adults, to be honest, having plunged into far from gentle waters, run back. Not comfortable!
So it was on the Anapa beaches in early July.
Anapa water temperature chart:
Average daily data. As you can see the coldest water east coast Black Sea in Anapa.
First version. Coastal upwelling - this is the name of the phenomenon of the rise of deep sea waters to the surface. That is, the mixing of water, sometimes they also say "turning the sea." For various reasons, surface warm water sinks into the depths, and colder deep layers of water take its place.
The simplest cause of cold water is the wind blowing at a certain angle from the warm land. It drives away the heated mass of water near the shore inland. And the night wind, on the contrary, drives cold sea waters to the shore.
Cyclones of the North-West continue their influence, we feel their Atlantic cold breath and we are here.
To what extent are the surface waters of the Black Sea cooled during upwelling? The difference reaches from 1-2 to 10-15 degrees Celsius. Sometimes there are very sharp jumps in temperature up to 20 °.
When will the water start to warm up? Not right away. Most often, the phenomenon lasts from 2 to 10 days in the period from June to August.
Second version Other experts talk about the influence of the surge phenomenon, which is more typical for winter, but more and more often it began to manifest itself in summer. As a result of it, the water level in the sea, its temperature changes. The cause of the phenomenon may be poor ecology. The same is a constantly observed bloom of water caused by an excess of algae, that is, eutrophication. Plants devour oxygen, soluble in water, which leads to life problems in animals and fish, and therefore to their death. On satellite images you can see how the color of the Black Sea water differs from others. There is simply no one to purify the water, because the microorganisms living here that cope with this have been exhausted.
Third version: the reason is the deep-water pipelayer of the South Stream gas pipeline, aimed at Turkey and located in the Anapa Black Sea waters, just in the area near.
By moving the bottom masses, while strengthening the structures, it raises cold silts to the surface, which cool the water. Sometimes accidental spills of oil products occur, both near the shore and in the waters. And all human activity is aimed not at cleansing, but at polluting the sea.
Fourth reason- self-purification of the sea. A forced process initiated by the sea itself to cool the water to stop the growth of algae and conserve oxygen in the water. Where upwelling often occurs, the water is more saturated with phosphorus, nitrogen and carbon dioxide. This stimulates the development of phytoplankton, which crustaceans love to eat and therefore provides food for fish.
Whatever it was, you will have to wait a little or start the hardening process, because water at + 21º + 22º cannot be considered cold, given the belt location of our country. So let's not bask and let's accept what nature gives us with gratitude.
Problems of the Black Sea
About environmental issues in general, and in the Anapa region in particular, they have been talking a lot for a long time, but so far they are only talking. The degree of its pollution has long exceeded all conceivable limits. Anapa has its own trouble - the water blooms! A long-standing problem caused by algae such as damask is not detrimental to the sea, and is even beneficial to human health. We do not consider the aesthetic side.
However, the fact that every year the degree of growth of the algae population in the sea becomes more and more, the volume of distribution is ever wider, and even the installation for catching "green wealth" and recycling acquired by the city does not bring results, is alarming. Despite the coolness, Kamka has already begun its flowering. This, most likely, indicates a violation of the balance of the ecosystem. It is not so easy to fight with nature itself.
Three days ago, together with my guests, I visited all b and her to testify with my own eyes the state of the beaches. The water is actually a little cooler than usual for this time of year, I would even say coldish and did not cause an ardent desire to swim.
Especially low water temperature in the Sukko area, barely exceeding +20, but quite clean and transparent:
On the city beach and the beaches of Dzhemete, as I said, there has already been a tendency for the water to bloom.
Today, after just three days, the sea is getting warmer, the process has started :-). Swimming becomes a pleasure. But for the norm, a couple of degrees are still not enough.
The world's bluest Black Sea turns turquoise
The fact that the Black Sea changes its color in different periods of the year and even the day from dark blue to turquoise has long been known, in any case, immediately upon arrival here, we drew attention to this fact, which is considered quite normal. Moreover, the sea was painted with stripes, those closer to the coast had a pronounced turquoise hue.
Big Utrish, early June 2017. The water really looks a little turquoise.
However, the acquisition of turquoise shade by water becomes permanent. For me, this color is very beautiful, but any phenomenon must have an explanation.
The fact was reported by NASA in the Argumenty Nedeli weekly https://argumenti.ru/science/2017/06/538988.
The well-known American agency backed up its statement with photographs, but the Americans have not yet been able to name the reasons for this phenomenon. Our scientists, as always, are silent. And how would they know? After all, to monitor the situation, to study the underlying processes - you need money, which, as always, is not available for such needs.
The first version of the color change is ecological: the invasion of a special type of phytoplankton, which, by absorbing oxygen, causes irreparable harm to the animal world.
This fact may explain another phenomenon in the Black Sea: the increasingly frequent voluntary release of dolphins onto land. The bodies of these intelligent animals can often be found on the seashore. They simply do not have enough oxygen in the water.
Why did the unfamiliar plankton, unusual for the sea, settle? Most likely, these are the consequences of that ecological sluggishness, mismanagement of human activity, and what is there, complete permissiveness, which can lead to an ecological catastrophe.
The sea itself is trying to solve the problem of water purification and cooling, which is why the very upwelling is launched - the mixing of cold deep layers with warm ones, which inhibits the development of microorganisms, purifying the water.
GENEVA, RIA Federal Press. The World Meteorological Organization released a report stating that in 2013, the concentration of carbon dioxide in the atmosphere reached a record high for the past 30 years.
In the future, this could threaten with a catastrophe: acidification of the oceans and the extinction of entire species. The survival rate of some marine organisms, including corals and molluscs, may fall sharply, writes ITAR-TASS.
Scientists have calculated that the rate of increase in the concentration of carbon dioxide in the atmosphere will only increase, at least until the middle of the 21st century. The ocean absorbs about a quarter of all carbon dioxide emissions from human activities on the planet, which does not occur without leaving a trace.
This once again proves that the Black Sea is a living biosystem, with its own character, disposition, laws of development and connection with the universe. Everything in nature is linked and interconnected, and if human activity does not fit into the general order of things, nature begins to change itself, often to the detriment of humanity. What we are convinced of over and over again more and more often.
So maybe it's time to seriously think about the consequences of our activities. At least to the best of your ability not to pollute the spaces around?
I will finish the topic from where I started .... The Black Sea is warming up day by day and is waiting for guests, embracing with its foamy waters everyone who longs to meet him. Waters, albeit slightly turquoise ....
Black Sea water in June 2018
PS: Yesterday 4 June 2018 at The Department of Civil Defense and Population Protection of the resort introduced a temporary ban on swimming in the Black Sea on all beaches of the resort. Swimming in the waters is prohibited due to the low sea temperature until June 5. All responsible persons working in the field of tourist services, parents were given recommendations on strengthening control over compliance with the ban.
Yesterday the water temperature was +17º, in some areas up to +16.5º. The ban on swimming in the sea is not only a warning. If vacationers of the resort ignore it, they will face a fine in the amount of 1 to 5 thousand rubles.
What caused the decrease in water temperature in the Black Sea in June 2018? Still the same cold currents that were driven by the northwest wind that blew from the Atlantic with strong gusts all last week.
The official opening of the holiday season in Anapa will take place on June 11. By this time, we hope, the water will warm up a little to the required +18, and swimming will resume. Or maybe tomorrow. :)
And here is July 8, 2018 streams of sea cold water from the southern waters from Sochi reached Anapa. The swimming season is again suspended, only the brave ones swim in the icy streams of the Black River, which have dropped to +16º on the beaches of Anapa, and even less than +13º in Novorossiysk. Forecasters predict a recovery of the situation by July 13. But only the Black Sea itself knows when it will again be pleasantly warm, comfortable and soft in summer.
Why can't you swim in cold water? Everything is simply banal. "Walrus" - upwelling on the drum. For everyone else, it is fraught with cramps of the limbs, which leads to death and possible colds. Yes, it's just uncomfortable.
Black Sea summer 2019
The holiday season was opened a week ago. The water approached the mark +21º +22º. And today, in the Dzhemete area, on June 18, I personally experienced a cold sea current. The water is not higher than +18, really cold. Brrr!!! People hardly swim. The beaches are deserted. Peace and quiet!
So only a few daredevils. I think the reasons are the same as above. By the way, damask-algae appeared. Anapa's trouble.
Although a week ago the sea was clean and the water was warm. Rather, algae began to grow in warm water, and for self-purification, the sea "turned over" again. I think two, three at most five days and the water will become warm again.
Summer is running out, but the Black Sea in the Anapa region has not yet pleased us with its warm jets. Doesn't make it to +24. Even in Dzhemet in milky water it is cool, it is even colder in Sukko and in B. Utrish - it is deeper there. But the sea coolness invigorates at night, despite the 30-degree heat during the day. And it pleases. 2019- best summer for us residents of Anapa. I sympathize with the guests. On the other hand, it is more comfortable to rest, there is no heat and stuffiness.
This is how cold summer 19 is 🙂
Currently, the water in the Black Sea is very, very cold. You can only wash your feet, and then, a hardened person. However, experts believe that after a few days the water will become much warmer, so you can fully relax.
So, weather forecasters assure that the sea will become warmer after the twelfth day of the current month.
At this time on Russian resorts a lot of people. Everyone goes only to get to the sea, because on the territory Russian Federation there are no resorts where you can swim in the sea all year round.
However, now luck has turned away from tourists, so for now you can only enjoy the sea views, and the most courageous can wash their feet in the sea. Now the sea temperature is very low to dive and enjoy the summer. Experts note that the water will begin to warm up only after the twelfth of July.
So, the resorts located in Sochi and Novorossiysk are not very relevant. In the past few days, the water temperature in Sochi has been at thirteen degrees, and in Novorossiysk - twenty.
You can swim in the Black Sea only in Anapa and Gelendzhik, because here the temperature reaches twenty-six degrees.
In addition, upwelling can be seen in Sochi. This is a phenomenon during which the wind pulls back warm water, instead of which cold waves wash up on the shore. In the Black Sea, the difference can reach up to sixteen degrees.
Why is the water in the Black Sea so cold?
Well, in fact, why in mid-July, doctors and the Ministry of Emergency Situations in Anapa give recommendations on limiting swimming for organized groups of children due to the low temperature of the water in the sea. And adults, to be honest, having plunged into far from gentle waters, run back. Not comfortable!
The first simplest explanation of the situation is given by experts involved in the study of sea water quality: The cold spring and the summer that does not begin for a long time could not warm up the deep waters in time. And even now the weather in the Central region does not indulge us, and here on the Black Sea coast the nights are still cool and, despite the fact that the heat has set in throughout the day, it will not be able to save the situation at once. The Black Sea is not a bath or a font; it will not work to warm up a colossus with a volume of 555 thousand km³ at once.
The second version Other experts talk about the influence of the surge phenomenon, which is more typical for winter, but more and more often it began to manifest itself in summer. As a result of it, the water level in the sea, its temperature changes. The cause of the phenomenon may be poor ecology. The same is a constantly observed bloom of water caused by an excess of algae, that is, eutrophication. Plants devour oxygen, soluble in water, which leads to life problems in animals and fish, and therefore to their death. On satellite images you can see how the color of the Black Sea water differs from others. There is simply no one to purify the water, because the microorganisms living here that cope with this have been exhausted.
Forecasters explained why it is forbidden to swim in the waters of Anapa
Kuban weather forecasters said that the water temperature at the height of the swimming season decreased along the entire northern part of the coast Krasnodar Territory. The cold center is located in Novorossiysk, where the sea "froze" to 13 degrees, in Tuapse the water is 16 degrees, the same in Anapa.
The decrease in temperature in the Black Sea in summer is usually caused by cold currents that come close to the coast. The movement of air masses also plays a role.
According to the employees of the hydrometeorological center of the Krasnodar Territory, tourists in Anapa and other cities will very soon again be able to treat themselves to sea bathing. “In general, warm water is returning, and it is enough for us that the wind changes, and everything will be fine for vacationers. Literally two or three days and everything will change, ”the weather service noted.
However, periods of cooling may repeat several more times during the summer.
“Literally in a few days, the surge (of water temperature) may begin again, and it cannot be said that cold water will go away, only warm water will remain. Everything depends on small synoptic processes,” the hydrometeorological center said.
