Rating of seas by salinity
There are about 80 seas on our planet. Of course, the Dead Sea would take first place in the ranking, since its waters are famous for their salinity. The Dead Sea is one of the saltiest bodies of water on Earth, salinity is 300-310 ‰, in some years up to 350 ‰. But scientists call this body of water a lake.
- Red Sea with a salinity of 42‰.
The Red Sea is located between the shores of Africa and Asia. The Red Sea, in addition to its salinity and warmth, boasts its transparency. Many tourists love to relax on its shores.
2. The Mediterranean Sea has a salinity of 39.5‰.
The Mediterranean Sea washes the shores of Europe and Africa. In addition to salinity, it can also boast of its warm waters - in summer they warm up to 25 degrees above zero.
3. Aegean Sea with a salinity of 38.5‰.
The waters of this sea with a high concentration of sodium can cause skin irritation. Therefore, after swimming it is better to take a fresh shower. In summer, the water warms up to 24 degrees Celsius. Its waters wash the shores of the Balkan Peninsula, Asia Minor and the island of Crete.
4 . Ionian Sea with a salinity of 38 ‰.
This is the densest and saltiest Greek sea. Its waters allow slow swimmers to hone this skill, as the high density will help keep the body afloat. The area of the Ionian Sea is 169 thousand square kilometers. It washes the shores of Southern Italy, Albania and Greece.
5 . The Sea of Japan, whose salinity is 35‰
The sea is located between the continent of Eurasia and the Japanese islands. Its waters also wash the island of Sakhalin. The water temperature depends on the geographical location: in the north – 0 -+12 degrees, in the south – 17-26 degrees. Square Sea of Japan more than 1 million square kilometers.
6. Barents Sea with salinity 34.7-35 ‰
This is the marginal sea of the Arctic Ocean. It washes the shores of Russia and Norway.
7. Laptev Sea with a salinity of 34‰.
Area - 662 thousand square kilometers. It is located between the New Siberian Islands and Severnaya Zemlya. The average annual water temperature is 0 degrees Celsius.
8. Chukchi Sea with a salinity of 33‰.
In winter, the salinity of this sea rises to 33‰, while in summer the salinity decreases slightly. The Chukchi Sea has an area of 589.6 thousand km². average temperature in summer - 12 degrees Celsius, and in winter - almost 2 degrees Celsius.
9. White Sea also has high salinity. In the surface layers the figure stopped at 26 percent, but at depth it increases to 31 percent.
10. Laptev Sea. Salinity at the surface is recorded at 28 percent
The sea has a harsh climate with temperatures below 0°C for more than nine months of the year, sparse flora and fauna, and low population along the coast. Most of the time, with the exception of August and September, it is under ice. The salinity of sea water at the surface in the northwestern part of the sea in winter is 34 ‰ (ppm), in the southern part - up to 20-25 ‰, decreasing in summer to 30-32 ‰ and 5-10 ‰, respectively. The salinity of surface waters is strongly influenced by the melting of ice and the runoff of Siberian rivers.
There are about 80 seas throughout our planet. All of them enter the waters of the World Ocean. As everyone knows from school, the seas are salty, but they all differ in the saturation of different compounds. Below is a ranking of the saltiest seas on Earth.
The White Sea, whose salinity is ‰.
One of the smallest seas on the planet is also one of the saltiest. Its area is only 90 thousand square kilometers. The water in it warms up to 15 degrees above zero in summer, and drops to 1 degree Celsius in winter. About 50 species of fish live in the White Sea.

The Barents Sea has a salinity of 35‰.
The Barents Sea is the saltiest of all located in the territory Russian Federation. It is adjacent to, but is almost 16 times larger in area. The waters are full different types fish due to the fact that the water temperature in summer is about 12 degrees Celsius. And this attracts many marine organisms, which, in turn, attract predatory fish.
The Sea of Japan, whose salinity is 35‰, is in 6th place in our ranking.
This sea is located between the continent of Eurasia and the Japanese islands. Its waters also wash the island of Sakhalin. The Sea of Japan is considered one of the saltiest seas in the world. The water temperature differs depending on the geographical location: in the north – 0 -+12 degrees, in the south – 17-26 degrees Celsius. The area of the Sea of Japan is more than 1 million square kilometers.
The Ionian Sea is 3‰ higher in salinity than our previous record holder.
This is the densest and saltiest Greek sea. Its waters allow slow swimmers to hone this skill, as the high density will help keep the body afloat. In summer, the water warms up to 26 degrees above zero. The area of the Ionian Sea is 169 thousand square kilometers.
Aegean Sea with a salinity of 38.5‰.
This sea takes 4th place in our ranking. Its waters with a high concentration of sodium can cause irritation to human skin. Therefore, after bathing in it, you should take a fresh shower.

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. Considering the geographical features, even in summer time 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 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.
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 because high level 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.
Thanks to the influence 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 it is transported throughout the country. king crab. 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 ranges from -1...+13 °C.
Undersea world 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 ending swimming season mark a cooling of up 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.
Underwater flora of the Aegean and Ionian seas 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 precisely on sea inhabitants.
Between Middle East Asia and the African continent, the picturesque Red Sea stretches its waters, which is part of 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 you throw everything away legal nuances...salinity Dead Sea- 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 most salty sea, washing the shores of our country, is Japanese. 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.
Sometimes this question is answered: “Dead Sea.” This is the wrong answer. Although this body of water is called a sea, the Dead Sea actually has no drainage and is therefore a lake. And argues for the palm in the competition for the saltiest lakes peace.
And the saltiest thing sea- this is the Red Sea. It is located in a tectonic depression up to 3 km deep between the Arabian Peninsula and the African continent, being an inland sea of the Indian Ocean. The climate here is very hot and arid, therefore, on the one hand, precipitation is very rare (no more than 100 mm per year), and evaporation from the sea surface is strong (2000 mm per year). Not a single river flows into the Red Sea, and the water deficit is replenished from the Gulf of Aden (in the south). As a result, the salt content in 1 liter of Red Sea water reaches 41 g (41‰). For comparison: in the Mediterranean Sea, with which the Red Sea is connected through the Suez Canal, the salt concentration is 25 g/l.
Geographical position red sea
(physical card)
Due to the fact that no rivers flow into the Red Sea, the water in it is crystal clear and transparent, because the rivers carry silt and sand with them. Thanks to the hot climate off the coast of Egypt and the heating of the sea “from below” by the heat of the planet’s core, the water temperature does not drop below +20°C even in winter, and reaches +27°C in summer. Therefore, the flora and fauna in this region are distinguished by rare diversity and beauty, making the Red Sea one of the most picturesque places on the planet. The Red Sea is especially attractive due to its extensive coral “gardens”, which can be seen without even sailing far from the shore. Corals make an additional contribution to the crystal cleansing process clean water sea, constantly filtering it. In total, there are more than a thousand species of fish, and about 30% of them are endemic (that is, found only in local waters).
Underwater world of the Red Sea
The reason for this phenomenon is the geological processes in the Red Sea region. Many years ago it was connected to the Mediterranean Sea by a narrow canal. Then, as continents formed and moved, this channel closed, and the Red Sea became completely isolated by land from other waters. The inhabitants of the sea, cut off from their relatives, began to adapt to new living conditions. Later, a narrow strait into the Indian Ocean, Bab El Mandeb, was formed in the south of the Red Sea. This is the narrowest and shallowest place in the Red Sea and today remains a barrier to the movement of marine animals from sea to ocean and back.
The water in the Red Sea mixes very well and evenly. In winter, surface waters cool, become denser and sink, while warm waters rise upward from the depths. In summer, water evaporates from the surface of the sea, and the remaining water becomes saltier, heavier and sinks. In its place rises less salty water. Thus, all year round the water in the sea is intensively mixed, and throughout its entire volume (except for the depressions) the sea is the same in temperature and salinity.
Eilat resort on the Red Sea coast (Israel)
In the 60s of the 20th century, depressions with hot brines were discovered in the Red Sea. At the moment, more than 20 such depressions are known. The brine temperature in them is in the range of 30-60°C and increases by 0.3-0.7°C per year. This means that the depressions are heated from below by the internal heat of the Earth. Observers diving into the depressions on underwater vehicles, they say that brines do not merge with surrounding water, but clearly differ from it and look like muddy soil covered with ripples, or like swirling fog. Chemical analyzes have shown that the content of many metals in brines, including precious ones, is hundreds and thousands of times higher than in ordinary sea water.
There are about 73 seas on Earth. They are part of the World Ocean. All objects are divided into various classifications. One of the criteria is the salinity of the water. Depending on this indicator, objects are divided into highly and lightly salted. The saltiest sea in the world has been established. It is the Red Sea. Several objects have a controversial status. They are not classified as seas, but according to a number of indicators they are salt lakes. This applies to the Dead and Aral Seas. The latter is almost completely dry.
In Russia, even bodies of water that are part of the Arctic Ocean are characterized by a high content of sodium chloride. The territory of the Russian Federation is washed by one object in which the salt level exceeds similar indicators in other seas. It is located in the east of the country. This is the Sea of Japan. The salinity of its waters ranges from 33.7% to 34.3%. This value lower than in the waters of the World Ocean. But in fact, this is the saltiest sea in Russia. This object is part of Pacific Ocean. It washes the territories of not only Russia, but also Japan, as well as two Koreas.
In the Russian Federation there are lakes in which the concentration of salts is regarded as very high. One of them is Bearish. This salt Lake is an analogue of the Dead Sea in Russia. It is located on the territory of the Kurgan region. Medvezhye is located in the interfluve of two reservoirs - Tobol and Ishim. The salt concentration in it reaches 360 g/l.
High mineralization rates are also observed in lakes Elton and Baskunchak. The first is located in the Volgograd region, the second in the Astrakhan region. In Elton, the average salt concentration is 279 g/l, and in some places 500 g/l. In Baskunchak - 300 g/l.
Top 10 saltiest seas in the world
The mineralization indicator in a separate object is determined based on the sodium chloride content in a liter of water. Researchers continue to debate which is the saltiest sea in the world. A number of scientists classify some objects as lakes and do not consider them in any other status.
The list of the saltiest seas in the world includes:
- Dead;
- Red;
- Mediterranean;
- Aegean;
- Ionic;
- Japanese;
- Barentsevo;
- Laptev;
- Chukotka;
- White.
Half of the objects on the list wash the shores of Russia. The status of the first on the list continues to be disputed.
Dead Sea
This object is considered an endorheic lake in Israel, as well as Palestine and Jordan. The average level of minerals in the waters of the site is 265 ppm. This value allows us to consider it one of the saltiest lakes in the world. At the same time, it is not too large in size: the length is 67 km, and the width is 18. The maximum depth is 306 meters. The Caspian is generally recognized as the largest salt lake in the world.
Red sea
This object is located between Africa and the Arabian Peninsula. It acts as part of the Indian Ocean. Its area is 450 thousand km2. It has the status of the saltiest on the planet.
The object is unique in that no rivers flow into it. There are 41 g of salts per liter of water. Even the open ocean contains only 34 grams of minerals. But the saltiest lake in the world (Dead) significantly exceeds the Red Sea in sodium chloride concentration. In the first, the salt level is 260-350 ppm, in the second - 41.
Mediterranean
Located between the African continent and Europe. Its area is 2.5 million km2. In some places the depth exceeds 5 km. It is among the top 3 objects of the World Ocean in terms of salinity. Its value fluctuates in the range of 36-39.5%.
The Mediterranean Sea also has the status of the warmest. In the eastern part it can warm up to 300C. Even in winter, in its northern part the water temperature does not drop below 80C.

Aegean
Is semi-closed. It washes Turkey and Greece. It is considered one of the saltiest. The mineralization of its waters is 37-39 ppm. In some places the salt concentration reaches 40%. It is the oldest body of water on the planet. Its age exceeds 20 thousand years.
Ionian
It is part of the Mediterranean, located between the Balkans and the Apennines and the islands of Sicily and Crete. Salinity reaches 38 ppm. This allows it to be included in the top 5 objects of the World Ocean in terms of mineralization level.
Japanese Sea
It is considered the saltiest in Russia. The sodium chloride content in it reaches 34.3 ppm. The area exceeds 1 thousand km2. The most great importance The depth of the object is 3.7 km. In the north, the reservoir is covered with ice.
The object is part of the Arctic Ocean. It washes the coastal zones of Norway and the Russian Federation. The area in the southwest does not freeze due to the influence of the warm North Atlantic Current.
The salinity of the reservoir is uneven. Her highest values are observed in the southwestern part and amount to 35 ppm. Less salinity is observed in the north - no higher than 33. The salinity of the object changes with the change of seasons. In summer in the coastal zone it does not exceed 32 ppm, and in winter it increases to 34.5.
Laptev
It washes the northern part of Siberia. Its area is 672 thousand km2. The highest salinity of the object is in its northwestern zone. In winter it reaches 34 ppm. In the south, salinity is much lower - no more than 25. In summer, the concentration of substances in sea water in the north drops to 32 ppm. In the south it ranges from 5 to 10. High salinity is observed in the depths of the waters. There its values reach 33 ppm. The Laptev Sea is considered one of the most severe water bodies in terms of climate.
Chukotka
The object is also part of the Arctic Ocean. It is located between Alaska and the Chukotka Peninsula. The salinity of the reservoir in the winter months ranges from 31 to 33 ppm. In summer its value drops to 28-32. At depth, mineralization increases. The reservoir has a harsh climate.
White Sea
The object washes the northern part of the European territory of Russia. Due to the significant influx of water from rivers, it has relatively low salinity. Its value is 26 ppm. In deep waters, salinity increases to 31.
Features of flora and fauna
The flora and fauna of the world's saltiest seas is diverse. The Dead Sea is almost completely lifeless. Neither fish, nor animals, nor plants live in it. Adapted to high salinity only higher mushrooms.
The Red Sea is unique for its variety of corals. lives there a large number of fish Also found are bottlenose dolphins, killer whales, green turtles, sharks and moray eels.
Flora Mediterranean Sea doesn't have a lot of variety. Its waters are dominated by different kinds seaweed Animal world represented by crayfish, turtles, stingrays, octopuses, crabs, squids, jellyfish and lobsters. There are over 540 species of fish there.
The flora of the Aegean and Ionian seas is identical to that of the Mediterranean. The fauna is diverse. The Aegean is rich in sponges, fish and octopuses, the Ionian - especially mackerel, flounder and tuna.
The fauna and flora of the Sea of Japan is heterogeneous. In the north it is less diverse than in the south. Laminaria and sea anemones live there. The waters are rich sea urchins and stars, scallops, shrimp. In May there are crabs there.
Algae and plankton are common in the Barents Sea. There are also about 20 species commercial fish. Previously introduced Kamchatka crab and snow crab are found there. The most common mammals are seals, beluga whales, polar bears and seals. There are numerous bird colonies along the coast.
The flora and fauna of the Laptev Sea are not very diverse. There are 39 types of fish living there. Sardines, flounder and cod are common. Among the mammals there are seals, sea hares, walruses and seals. Several dozen species of birds live here.
In the Chukchi Sea, the flora is sparse due to the severity of the climate. The most common animals are polar bears and walruses with seals. There are whales. The fish world is rich polar cod and grayling.
How is water salinity measured?
The basic unit of this indicator is ppm. It refers to the amount of solid substances dissolved in a kilogram of sea water. Chemical analysis does not accurately measure the degree of mineralization of a liquid. Sea water too complex in its composition. Its salinity is determined by the concentration of one of the elements of the composition, by electrical conductivity or refractive value. Based on these methods, a rating of sea salinity is compiled.

Summing up
The Dead Sea is considered the most mineralized sea in the world. A number of researchers classify it as a lake, which allows us to consider the Red Sea to be the leader in the rating. In Russia, the saltiest sea is the Sea of Japan. The lake with the highest mineralization is Medvezhye.
Five seas from the top 10 rankings are considered northern waters. All of them wash the territory of the Russian Federation. The scarcest of animals and flora is the Dead Sea. In other objects there is a wide variety of fauna. The richest in flora is the Red Sea.
