The saltiest seas in the world
There are about 80 seas all over the world, which are an integral part of the World Ocean. All these waters are salty, but among them there are record holders, which are distinguished by a high concentration of salts and other minerals in their composition. The Baltic Sea is considered the freshest sea on the planet, its salinity is only 7 ‰ (ppm), which is equal to 7 grams per 1 liter of water. Among all the others, we singled out the saltiest seas in the world.
10. White Sea | Salinity 30‰
It is considered one of the saltiest seas in the world. Salinity here can reach 30‰ in places. This is one of the smallest seas in Russia, with an area of 90,000 square meters. km. The temperature here rises to 15 degrees in the summer and drops to minus 1 degree in the winter. The inhabitants of the White Sea are about 50 species of fish, including beluga whale, salmon, cod, smelt and others.
9. Chukchi Sea | Salinity 33‰
It is one of the ten saltiest in the world. Its salinity in winter is higher and can reach 33‰. It is located between Chukotka and Alaska on an area of 589,600 sq. km. The water temperature here is quite low: in summer – 12 degrees above zero, and in winter – minus 1.8 degrees. Walruses, seals, as well as fish - grayling, polar cod, Far Eastern navaga, Arctic char and others live here.
8. Laptev Sea | Salinity 34‰
Occupying an area of 662,000 sq. km., is considered to be the saltiest in the world. It is located between the New Siberian Islands and the Severnaya Zemlya Islands. The salinity of its waters reaches 34‰ in some places, and the water temperature does not rise above 0 degrees all year round. Walrus, sterlet, sturgeon, perch and other animals live in the depths of the sea.
7. Barents Sea | Salinity 35‰
Having a salinity of 35‰, it is one of the saltiest on earth and the saltiest in Russia. It is washed by the waters of the White Sea and has an area of 1,424,000 sq. km. In winter, only the southwestern part of the sea does not freeze; the temperature here in summer does not exceed plus 12 degrees. The underwater world here is quite rich in fish, including capelin, perch, herring, catfish, killer whale, beluga and others.
6. Sea of Japan | Salinity 35‰
Located between the shores of Eurasia, the Japanese islands, and the island of Sakhalin, it is considered one of the saltiest in the world. Its salinity reaches 35‰. The annual water temperature ranges from 0–+ 12 degrees in the north, and in the southern part 17-26 degrees above zero. The fauna here is very rich and includes many species of fish. Herring, pollock, navaga, flounder, pink salmon, chum salmon, anchovy, crabs, shrimp, oysters, squid and many others live here. Japanese salt waters occupy an area of 1,062,000 sq. km.
5. Ionian Sea | Salinity 38‰
considered the densest and saltiest in Greece. It is perfect for those who do not know how to swim and want to learn. In summer, the temperature here ranges from 25-26 degrees above zero, and in winter it drops to plus 14 degrees. The salinity of the sea is about 38‰. The inhabitants of salt waters are fish such as tuna, flounder, mackerel and others. The Ionian Sea occupies an area of 169,000 sq. km.
4. Aegean Sea | Salinity 38.5‰
Aegean It is one of the ten saltiest seas in the world. Its salinity is about 38.5‰. Due to the high salinity, after swimming in such water it is recommended to wash with fresh water, since a high concentration of sodium can adversely affect the skin and mucous membranes. Winter temperatures here are about 14 degrees above zero, and summer temperatures are plus 24 degrees. It is inhabited by octopuses, sardines, sponges and other inhabitants. It is located between the peninsulas of the Balkans, Asia Minor and the island of Crete. The Aegean Sea has existed for about 20,000 years. It was formed as a result of the flooding of the Egenida landmass and occupied an area of 179,000 sq.m. Its appearance led to the formation of the islands of Crete, Lesbos, Euboea and others.
3. Mediterranean | Salinity 39.5‰
Located between Europe and Africa. It is rightfully considered one of the saltiest seas in the world, with salinity reaching 39.5 ‰ in some places. It also belongs to the warmest seas of the World Ocean - the temperature here is plus 25 degrees in summer and minus 12 degrees in winter. It is inhabited by seals, sea turtles, as well as more than 500 species of fish, including sharks, stingrays, blennies, lobsters, crabs, mussels and many, many others.
2. Red Sea | Salinity 42‰
Located between Africa and Asia, it is one of the saltiest on planet Earth. Its salinity reaches 42 ‰, which is about 41 grams per liter of water. A very rich underwater world is concentrated here: sharks, dolphins, stingrays, moray eels and other living creatures are the inhabitants of the Red Sea. The water temperature is 25 degrees above zero all year round. In the Red Sea, the water is very well and evenly mixed. In winter, surface waters cool, become denser and sink, while warm waters from the depths rise upward. In summer, water evaporates from the surface of the sea, and the remaining water becomes saltier, heavier and sinks. Less salty water rises in its place. Thus, all year round the water in the sea is intensively mixed, and throughout its entire volume the sea is the same in temperature and salinity, except in the depressions. In addition, the sea boasts amazing transparency.
1. Dead Sea | Salinity 270‰
- the saltiest in the world, which is located on the border of Israel and Jordan. The mineral content is about 270 ‰, and the salt concentration per 1 liter reaches 200 grams. The composition of the salts of the sea differs significantly from all others. It consists of 50% magnesium chloride, and is also rich in potassium, bromine, calcium and many other mineral elements. Potassium salts are artificially crystallized from its water. The water here has the highest density, which is 1.3-1.4 g/m³, which completely eliminates the possibility of drowning. In addition to unique salts, the sea contains healing mud, which contains 45% salts. Its features are a high pH value of 9, as well as a bitter and oily taste. Sea temperatures can reach 40 degrees above zero, which creates intense evaporation and contributes to high density. If in other waters with high salinity there are diverse inhabitants, then in the waters of the Dead Sea it is impossible to meet them.
In our country, the sea is considered the saltiest Barencevo sea. The surface layers of this sea show a salinity of 34.7% to 35%.
White Sea also has a high percentage of salinity: 31% at depth and 26% at the surface.
Kara Sea characterized by high salinity up to 34%. However, in the Kara Sea it is extremely scattered, and in some areas - at the mouths of rivers, for example, the water can be almost fresh.
Chukchi Sea And Laptev sea have a salinity index of 33 and 28 percent, respectively.
Mediterranean Sea is one of the saltiest in the world. The salinity of this sea is 36-40%. The high salinity of the Mediterranean Sea limits the development of zoo and phytoplankton. However, high salinity does not interfere with fauna, of which there is plenty in this sea.
Legends and scientific facts about the salinity of the seas
Therefore, the saltiest sea on Earth is considered Red sea, which has a salinity index of 41%. Not only does the Red Sea have extremely high salinity, but the salinity level is also very evenly distributed.
Answer from Natalya[guru]
According to personal feelings - Mediterranean, more salty Aegean, the saltiest - Red. Then - Dead. And % - you need to look...
Salinity is the amount of solids in grams dissolved in 1 kg of sea water, provided that all halogens are replaced by an equivalent amount of chlorine, all carbonates are converted to oxides, and organic matter is burned.
It is measured in “‰” (“ppm”).
The average salinity of the world's oceans is 35 ‰. To calibrate instruments, so-called normal water with a salinity close to 35 ‰ is extracted from the Bay of Biscay.

Answer from Marina F[guru]
Aegean Sea
Salinity 37.0-39.00/00.
Mediterranean Sea
Large evaporation leads to a strong increase in salinity. Its values increase from 3. to V. from 36 to - 39.5. The density of water on the surface varies from 1.023-1.027 g/cm³ in summer to 1.027-1.029 g/cm³ in winter.
Red sea
Strong evaporation of warm water turned the Red Sea into one of the saltiest on the globe: 38-42 grams of salts per liter. Salinity - 40-60 g/l. Salt content reaches up to 40‰
Dead Sea
The content of minerals in water reaches 33%, an average of 28% (for comparison in the Mediterranean Sea - 4%).
Barencevo sea
The salinity of the surface layer of water in the open sea throughout the year is 34.7-35.0‰ in the southwest, 33.0-34.0‰ in the east, and 32.0-33.0‰ in the north. In the coastal strip of the sea in spring and summer, salinity drops to 30-32 ‰, and by the end of winter it increases to 34.0-34.5 ‰.
Sea of Azov
The salinity of the sea before the regulation of the Don was three times less than the average salinity of the ocean. Its value on the surface varied from 1 ppm at the mouth of the Don to 10.5 ppm in the central part of the sea and 11.5 ppm near the Kerch Strait. After the creation of the Tsimlyansky hydroelectric complex, the salinity of the sea began to increase (up to 13 ppm in the central part). Average seasonal fluctuations in salinity rarely reach 1-2 percent.
Davis Sea
Salinity 33.0-33.5‰.
Baltic Sea
The salinity of sea water decreases from the Danish Straits, connecting the Baltic Sea with the salty North Sea, to the east. In the Denmark Straits, salinity is 20 ppm at the surface of the sea and 30 ppm at the bottom. Towards the center of the sea, salinity decreases to 6-8 ppm at the sea surface, in the north of the Gulf of Bothnia it drops to 2-3 ppm, in the Gulf of Finland to 2 ppm. Salinity increases with depth, reaching 13 ppm in the center of the sea near the bottom.
White Sea
The large influx of river water and insignificant exchange with the Barents Sea led to a relatively low salinity of the surface waters of the sea (26 ppm and below). The salinity of deep waters is much higher - up to 31 ppm.
Conducted site monitoring! Phew! Chocolate for you! !
The Black Sea is internal, its water area is surrounded on all sides by land, only narrow straits lead to the Mediterranean Sea. This entire area belongs to the Atlantic Ocean basin. The salinity of the Black Sea is lower than the Mediterranean and Red Sea. The flow of large rivers desalinizes the water area, but its mystery is the formation of a layer of heavier salt water at depth, the accumulation of dissolved hydrogen sulfide. All this does not interfere with beach and cruise holidays, shipping and fishing. After all, the surface layers are devoid of H 2 S and are well heated by the sun.
Cradle of ancient civilizations
The Black Sea is shaped like an oval, elongated in the latitudinal direction. This basin is almost closed, separated by large land masses from other parts of the World Ocean (MO). In the northeast, the Crimean Peninsula deeply cuts into the water area; its northeastern peninsula separates the Black and Azov Seas. The pool is located in the southwestern part of the Eurasian continent. Along its surface, from northeast to southwest, a border is drawn between two parts of the world - Asia and Europe.
The lives of millions of people have long been connected with the waters of the Black and Mediterranean Seas; legends about giants and monsters were born here, and the greatest discoveries were made. Suffice it to remember that the straits and the surrounding peninsulas and islands are associated with the legends about Scylla and Kharbid, the voyage of the Argonauts led by Jason to Colchis for the Golden Fleece. Even in ancient times, Greek sailors and traders highly valued the fishing wealth of this water area and created prosperous colony cities on the shores, the remains of which can be seen on the Crimean peninsula. It is difficult to say what the salinity of the Black Sea was in ppm several thousand years ago. This indicator was introduced relatively recently, when a consistent and targeted study of hydrological features began.
The most important geographical features affecting sea salinity
The narrow Bosporus and Dardanelles straits connect the Black Sea basin successively with the Marmara and Aegean Seas, leading to the Mediterranean, which, in turn, communicates with the Atlantic Ocean through the Strait of Gibraltar. All of the listed parts of the MoD are navigable and are located in the eastern part of the Atlantic. Physiographical features that significantly or moderately affect the salinity of the Black Sea:
- location in the northern temperate and subtropical climate zones;
- a large catchment area that determines the flow of fresh water from rivers;
- weak connection with the Atlantic Ocean and Mediterranean Sea;
- average depth 1240 m, maximum - 2210 m;
- absence of large tidal waves and low tides.
River flow
Many European rivers flow from west to east and from north to south. The largest natural channel of the Old World is the river. The Danube flows through 10 countries and brings huge amounts of fresh water to the Black Sea. Other large and medium-sized rivers in this basin: Dnieper, Don, Kuban, Bug, Rioni, Dniester.
Fresh river water mixes little with deeper and denser layers, so a significant part of the fresh runoff evaporates from the sea surface. But its volume is so large that it increases the level of the Black Sea water by 5 m relative to the average levels of the Atlantic Ocean. The temperature and salinity of the Black Sea, on the contrary, are lower than in neighboring parts of the Mediterranean Sea. This feature led to the birth of a current directed to the southwest, towards the Bosphorus Strait.
Water mineralization
By studying the salinity of the water of the Black Sea and other parts of the Moscow Region, researchers measure not only the total content of dissolved substances in various layers and parts of the water area, but also determine the elemental composition. In addition to H 2 O molecules, sea water contains gaseous substances, mineral and organic compounds in the form of ions, molecules and other particles. The main components of salts in the Black Sea: carbonates, sulfates, nitrates and chlorides of calcium, magnesium, sodium, potassium. The presence of these solutes is related to the composition of the rocks on land and the seabed. The salinity of the Black Sea is affected by various compounds coming from surface and underground runoff and precipitation. Chemical interactions occur between substances, which also affects performance.
Water is enriched not only with salts from dissolved minerals and rocks, but also with organic matter. A significant part of the surface of the Northern Black Sea region is composed of limestone, hence the high content of calcium, magnesium and sodium salts in the water. Basaltic rocks, when dissolved, increase the amount of silicon and iron. Substances contained in water increase its overall mineralization. It changes noticeably over the seasons, from the surface to the depths, from north to south, so reference books, textbooks and atlases may contain different indicators characterizing the salinity of the Black Sea. Most often, average values obtained based on long-term data are given.
What is salinity?
Almost the entire periodic table is present in sea water. But salinity is considered only the amount of dissolved substances in grams, which are obtained in solid form after evaporation of 1 kg of sea water. For convenience, this indicator is expressed as a percentage and ppm.
To facilitate calculations, the content of all halogens is equal to the equivalent amount of molecular chlorine. There are other features, for example, heating is accompanied by the removal of dissolved gaseous substances. When the sediment is heated, the organic matter decomposes.
Salinity of the Black Sea in percent
To characterize the studied indicator as a percentage, you need to remember what the content of the dissolved substance in 100 g of solution is called. This is the mass fraction, its percentage value can be found by dividing the mass of the solute by the mass of the solution and multiplying by 100%. Let’s say that when 1000 ml of water is evaporated, a precipitate is obtained whose mass is 17 g. The mass fraction (%) of dissolved substances is 1.7%.
Salinity of the Black Sea in ppm
Determining experimentally the mass of dissolved salts in terms of 1 kg of Black Sea water gives different indicators - from 8 to 22 g. To determine salinity in ppm, we take the value mentioned most often in the literature about the Black Sea - 17 g. Percentage is one hundredth of , and ppm is one thousandth part. Divide 17 g by 1000 g and multiply by 1000 (‰). Thus, we find that the average salinity of the Black Sea is 17‰ (ppm). For comparison, we present the average values for the World Ocean - 35‰. The salinity of the Red Sea is 42 ‰, the Kara Sea is 8 ‰. It turns out that the content of dissolved substances in the Black Sea water is almost 2.5 times lower than in the Red Sea.
A simple experiment to determine salinity
There is a way to find out on your own what mass of substances is contained in sea or fresh water. The experiment is simple and interesting, but to carry it out you will need heat-resistant dishes, a heater and a chemical balance. It is also necessary to take into account that the density of the saline solution is higher. Therefore, the mass of 1000 ml of sea water is greater than 1000 g. This means that without taking into account density, the calculations will be approximate.
To find out what the salinity of the Black Sea is, you will need 100-200 ml of sea water. The experience is as follows:
- Measure the volume and heat the selected liquid in an evaporation cup to a boil.
- When all the water has evaporated, a white residue will remain at the bottom of the dish.
- You need to collect the sediment on a piece of paper and weigh it on a scale.
- The result obtained is the total mass of all solutes in the sample.
How do salinity and water temperature indicators change?
The salinity of the Black Sea water in ancient times, as in subsequent centuries, was subject to fluctuations under the influence of climatic, meteorological factors, water regime in coastal regions and economic activities of the population. Water mineralization largely depends on the total flow of large and small rivers. During dry periods, the riverbeds become shallow, less fresh water flows into the sea, and the salt content increases.
The main patterns that have developed to date:
- the salinity of the surface layers of the Black Sea is 15-18‰, deep - 22.5-22.6‰;
- plumes of water of low salinity spread from the northwest along the coast to the south, from the southeast - along the coast of the Caucasus in a northerly direction;
- under the influence of river runoff, the salinity of the surface layer of the sea in the northwest can decrease to 10‰;
- salinity in the Bosphorus region increases with the rising water of the Sea of Marmara;
- The surface temperature in summer is 27-28 °C along the Black Sea coasts, in the central part of the water area - up to 22 °C;
- the maximum salinity of surface waters—18.3‰—is located in the east of the central part of the water area, south of Crimea.
- the maximum salinity at a depth of 100 m is located south of the Kerch Strait - over 20.6‰;
- from the surface to 150-200 m the temperature decreases and reaches about 9 °C;
- at a depth of 150 m there is practically no oxygen, hydrogen sulfide appears;
- In winter, the surface of the Black Sea cools greatly; in the northern part it can drop to sub-zero levels, but more often it remains at a level of 8-9 °C.
When freezing occurs, fluctuations in hydrological parameters are observed. Some areas of the water area are partially covered with ice; complete freeze-up rarely occurs. For example, chronicles have been preserved about how the Black Sea was covered with such strong ice in winter that traders could reach the Turkish coast on sleighs and on foot.
In general, the conditions of this water area are favorable for the development of flora and fauna. However, scientists have noticed that a decrease in salinity leads to a decrease in the biodiversity of the Black Sea. The fact is that the inhabitants of the World Ocean and its parts do not tolerate salinity below 20‰. For the population of Crimea, desalination of slightly salted sea water in the water area near the Sea of Azov is a solution to the problem of drinking and industrial water.
There are more than 70 seas on our planet. And all of them are an insignificant but integral part of the World Ocean. Researchers classify them into a variety of categories: size, location, depth, etc. One of these categories is the level of salt content in the water. We have compiled the top 10 saltiest seas in the world, and we will also tell you how exactly the salinity of the water in them is measured and who can live in the waters of such objects.
Determination method
The unit of measurement for water salinity, as well as the level of alcohol in the blood, was called ppm by scientists. 1 ppm refers to the volume of solids that are dissolved in 1 kg of seawater. The problem is that the composition of water in the seas is quite complex for direct chemical analysis. To determine the level of salinity, the concentration of an element and electrical conductivity are taken as a basis. Or they start from the magnitude of refraction. Using this method, biologists were able to determine which seas are the saltiest in the world.
At the very end of our list is the White Sea. Its waters wash the north of the European part of our country. The salt level here remains at 26-28%. This low level is due to the fact that a huge number of rivers flow into the White Sea. At depth, mineralization can reach 31 ppm.
It is worth saying that the White Sea is one of the smallest that washes the shores of Russia. Its area barely exceeds 90,000 km 2.
Fishing here is very developed: the average catch is around 2000 tons.
9. Chukchi Sea
In the waters of the Arctic Ocean, between Alaska and Chukotka, lies the Chukotka Sea, which occupies the 9th position in our ranking of the saltiest seas in the world, with an area of 590 km 2. Given the geographical features, even in summer, the water temperature rarely rises above 12 °C. In winter, it even drops to 0 °C. But, despite this, the salinity level here is slightly higher than that of the White Sea - 32-33 ppm.
The harsh climate that reigns in these latitudes also affects the inhabitants of the sea. Only the most resilient representatives of the fauna are able to survive in such conditions. Nevertheless, cod is the main object of fishing here.
The huge sea (more than 670 square kilometers) washing the north of Siberia is called the Laptev Sea and ranks 8th in our ranking of the saltiest seas. In winter, the salinity of its waters fluctuates at 34%. But in the southern part it drops sharply to 25%, and with the arrival of summer it can even drop to 5 ppm. As in all other seas, the maximum level (35%) is observed in the depths.
An interesting fact: despite the fact that the water temperature rarely rises above 0 °C, the Laptev Sea is especially loved by surfers from all over the world due to the high level of coastal waves.
If you want to organize fishing in the Laptev Sea, then you will face complete failure. Only 40 species of fish live here. True, giant flounder and sardines of gigantic size are often found.
Another body of water that is part of the Arctic Ocean. The Barents Sea washes the shores of Norway and the Russian Federation. It is considered the most dangerous in our country.
Due to the influence of the warm current from the North Atlantic, the salinity of the water here is constantly changing. True, it fluctuates in a small range: from 33 to 35 ppm. The level also depends on seasonality: in summer it is slightly lower.
The flora of the Barents Sea is rich in plankton. It is also from this reservoir that Kamchatka crab is transported throughout the country. But be careful: you can find aggressive polar bears and seals on the coast.
Occupying a middle position on our list, the Sea of Japan confidently tops the list of the saltiest seas in Russia. Despite the gigantic area of 1000 km 2, the level of NaCl (sodium chloride) in almost all its zones confidently remains at around 34%.
It is worth noting that the Sea of Japan is extremely cold. In the south, temperatures may drop below -27 °C. The average annual temperature fluctuates in the range -1...+13 °C.
The underwater world of the Sea of Japan is not stable. The northern part has much fewer inhabitants than the southern part. However, if you decide to enjoy large shrimp or scallops, the Sea of Japan will give you the opportunity. You can also find crabs on the coast at the end of spring.
Finally we are transported to where it is warm. Let's start on the shores of Greece. The Ionian Sea is considered to be both the saltiest sea in this country (38 ppm) and the densest in the world. If you are just learning to swim, then this pond will be a real gift for you. The waters of the Ionian Sea literally push you to the surface. It is precisely because of the high level of density that you are unlikely to be able to reach the bottom on your own. In summer, the water is warm, about +27 °C. Winter and the end of the swimming season are marked by a drop in temperature to +15 °C.
The shores of Greece are washed by another sea - the Aegean. Researchers found a concentrated alkali level of 39.5% here. If you plan to swim in its waters, you should listen to the advice of dermatologists and use a special cream after completing the procedures. It would also be a good idea to douse yourself with fresh water to wash away the sodium that settles on the skin.
The sea is believed to have formed more than 20,000 years ago. True, what size the reservoir was at that time is unknown. Today, the Aegean Sea stretches over an area of 180,000 km 2.
The underwater flora of the Aegean and Ionian seas is similar in many ways. Animals are different. If the Aegean abounds in octopus, then the Ionian is rich in flounder and tuna.
The top three winners on our list are the Mediterranean Sea. We all know it, many regularly visit its beaches, not even suspecting that the salinity level of its waters reaches 41 ppm.
The Mediterranean Sea stands out among others in several ways. Firstly, this is the warmest sea. Secondly, it is truly gigantic - its area is just over 2,500,000 km 2. And the greatest depth recorded by scientists exceeds 5 km.
Due to its enormous size, the Mediterranean Sea also boasts a variety of inhabitants. Its waters are home to just over 500 species of fish. It is not worth reminding that Mediterranean cuisine is based specifically on marine inhabitants.
Between Middle East Asia and the African continent lies the picturesque Red Sea, which is part of the Indian Ocean. The reservoir is relatively small - only 438,000 km 2. And this is a unique sea, into whose waters not a single river flows.
Despite the fact that the reservoir ranks second in the ranking of the saltiest seas, the world of its flora and fauna is very diverse. Here you can find sharks and killer whales, as well as mature turtles and dolphins. In addition, the diversity and beauty of coral reefs attracts many divers from all over the world.
It is immediately worth noting that many scientists still consider the reservoir to be a lake. But if we ignore all the legal nuances... the salinity of the Dead Sea is 270%! This is both a unique and amazing figure, which means that in 1 liter of water, chemical analysis showed 270 grams of alkalis. This is almost 10 times more than in the Red Sea. Naturally, nothing like this can be found on our plane anymore, so this is the saltiest sea on earth. Its mineral composition contains an impressive portion of the periodic table, including bromine and potassium. Is it necessary to warn that swimming in its waters is not worth it?
It's not called the Dead Sea for nothing. Only a few species of mushrooms can survive here. It’s definitely not possible to find random residents: the maximum depth of the sea-lake reaches only 300 meters, so 99.9% of the waters have already been studied and surveyed.
Summarizing the facts
As you can see, scientists are divided on which sea is the saltiest. Many geographers are firmly convinced that the Dead is a lake, not a sea, which is why they give the palm to the vice-winner of our rating - the Red Sea. Those researchers who do not care about such trifles argue in favor of the Dead.
Five objects from our list border on the territory of the Russian Federation, which cannot be ignored. The saltiest sea washing the shores of our country is the Sea of Japan. And from the lakes - Bear.
Now you know about the 10 saltiest seas. And which one is best suited for a resort holiday is up to you to decide.
