Sea – a salt water reservoir connected to one of 5 existing oceans on the planet. Some are inside the continents, others are part of the ocean. In the world there are about 90 marine reservoirs having different salinity, depth and size. Today it will be about the largest seas on the planet.

Sargasso Sea

Rating: 5.0

Sargasso Sea

  1. Area: 6,000,000 (7,000,000) km2
  2. Maximum depth: 6995 m

The Sargasso Sea is a real miracle of nature – the sea in the ocean. The only sea in the world without coasts. It served inspiration for the creation of the famous “Island of the Dead Ship.” Unfortunately, this is not such a fantasy: a huge amount sailing ships died in Sargasso waters due to the constant calm, reigning in these latitudes.

Interesting fact. The water of the Sargasso Sea is incredibly rich algae, the supply of which, according to some estimates, exceeds 11 million. tons Until recently, oceanographers believed that they were brought whirlpools from Cuba, the Antilles, off the coast of Mexico Gulf, etc. But it turned out that algae in the Sargasso Sea and born. Mariners began to call them “Sargassa”.

Since the Sargasso Sea is surrounded on all sides by the ocean, its currents bring a huge amount of garbage into the sea waters. Already managed to form a whole garbage island, which is considered serious environmental issue.

For some unknown reason, they annually sail to the Sargasso Sea. blackheads from Europe and America in order to lay eggs, and hatched offspring floats back “to their homeland.” In general, this the path takes away from young fish about 3 years of life.

Philippine Sea

Philippine Sea

  1. Area: 5,695,000 km2
  2. Maximum depth: 10,994 ± 40 m

The sea is not particularly interesting among residents of Europe and countries. former USSR, which is not surprising, because geographically it is too removed and often preferred to Red and Mediterranean the seas. But in vain, because those who were lucky enough to relax on the coast Philippine Sea, forever in love with its natural beauty – virtually unparalleled throughout the oceans.

Clear clear water, luxurious coral lagoons, riot greens and powerful tropical storms – all this is the Philippine Sea. Among all the seas of the planet, it is it that is considered the largest in area, if we talk about the seas that have coasts. If you exclude this factor, of course, the most impressive will be Sargassovo.

It is noteworthy that the waters of the Philippine have practically identical salinity over the entire area – in different parts fluctuations in salinity do not exceed 1%. For the local territories Underwater eruptions are not uncommon. At the same time, they fly to the surface incredible volcanic bombs, sometimes even washed up by the most real islands from the ashes. True, they are very fast. blurred.

Despite the magnificent seascapes, the Philippine Sea does not friendliness: from May to October (in rainy season) some of the most powerful hurricanes in the world are raging here. In addition, the Pacific Fire passes through the waters of the sea. ring – a zone of the highest seismic activity.

Interesting fact. It is here that the deepest point is located planets – Mariana Trench or as the Abyss is also called Challenger According to the latest data, the depth of this place is 10994 m.

Arabian Sea

Rating: 4.8

Arabian Sea

  1. Area: 3,862,000 km2
  2. Maximum depth: 5,803 m

The Arabian Sea got its name because since the 9th century and up to the late Middle Ages was one of the most important shipping destinations for Arab sailors. But the world doesn’t It was always known as the Arabian: it was also called Persian, Indo-Arabic, Green.

Arabian waters are characterized by a stable high temperature: here warm all year round. The water temperature ranges from 22-29 0C with a plus sign (the hottest month is May). Despite for year-round heat, swimming in the sea is possible only between October to May (during the remaining months it rises dangerously on the water high waves).

The Arabian Sea suffers greatly from proximity with two large ports – Mumbai (India) and Karachi (Pakistan). Its negative contribution made by companies that process oil and transport it from countries Persian Gulf. Nevertheless (fortunately, perhaps) the Arabian the sea is considered one of the cleanest seas in the world.

A curious fact for those who like to relax in the Maldives islands – they are not washed by the Indian Ocean, but by the Arabian by the sea.

Weddell Sea

Rating: 4.8

Weddell Sea

  1. Area: 2,800,000 km2
  2. Maximum depth: 6820 m

One of the most poorly studied seas – harsh climatic conditions and practically no outgoing ice significantly complicate study of its waters. Located in West Antarctica. Nearly all year round it is covered with a layer of ice, and the average monthly temperature water off the coast sometimes reaches -30 0С.

Weddell Sea is considered the cleanest on the planet: water is here so transparent that it allows you to see objects at a depth up to 80 m. A chemical study of water showed that it is close in composition to distilled. In this regard, the Weddell Sea may compete with Baikal.

It is quite deep (average depth is 3 km) and, in addition, the coldest in the world: the water temperature drops to minus, which leads to the formation of a thick layer of ice (sometimes it reaches 2 m). During such a period, staying in the Weddell Sea becomes deadly, because often a manifestation of an exciting and terrible at the same time phenomenon – “flash frieze” – instant freezing waves. If the ship falls into such a trap, on its own he can’t get out of it anymore.

Interesting fact. Mariners pass the old word of mouth legend: researchers have been around for a century periodically tell that they see a mermaid in sea waters, moreover, male.

You can see the cold sea open spaces only as part of research teams that are not sent to these waters and often.

The Caribbean has always been fanned by pirate romance: it is the largest number of filibusters and pirates lived here time. Although the life of a pirate is certainly difficult to name romantic. Nevertheless, to this day on the bottom of the Caribbean hidden under a layer of sand, countless treasures that got there together with sunken ships (according to rough estimates, their number reaches several tens of thousands).

And, although many divers are hunting for the treasure, find here something valuable is not so simple: the thickness of the seabed in in some places reaches one kilometer. Also Caribbean the sea is one of the most “inhospitable” in the world: here often fierce storms occur, the wind speed at the same time sometimes reaches 120 km / h

There are many islands in the Caribbean, 98% of which are uninhabited. But on the shores of the sea lives more than 100 million. person.

Interesting fact. Global warming negatively affects The waters of the oceans and the Caribbean are no exception. His numerous coral reefs are at risk: over 95% affected by climate change.

The cradle of modern civilization is never called Mediterranean Sea. Entire shores were born and died on its shores civilization, and in the waters, perhaps, the greatest number naval battles all over the world. It is the Mediterranean Sea that washes the largest number of countries on the planet – as many as 22. In addition, it is the only one that can surprise even experienced sailors: because The specifics of the local climate are often mirages.

Scientists associate the emergence of the sea with an ancient cataclysm, occurred over 5 million years ago: as a result of a powerful earthquake on the mainland its part in Gibraltar sank down and was flooded abruptly pouring into the gap formed ocean waters.

Despite the bewitching view, it is difficult to name the Mediterranean Sea friendly: sometimes the height of the waves in its waters can reach 8 meters. They sent to the bottom more than one hundred ships. Exact them the number still could not be counted – but the remains are found constantly.

Interesting fact. Ancient Romans modestly magnified the Mediterranean the sea “to one’s own.”

The Mediterranean Sea impresses with the wealth of the underwater world. Alone only fish there are more than 550 species. Unfortunately, the conditions in which underwater life develops are not the best. After all, the sea seems clear only during a vacation in Greek or the spanish coast. In fact, the waters of the Mediterranean are one of the dirtiest in the world.

After the digging of the Suez Canal, an interesting phenomenon occurred: The Red Sea “connected” with the Mediterranean. As a result has occurred insignificant exchange of flora and fauna – about 2% of inhabitants last got there from Red.

The most southern sea representing the Pacific basin. Washes the New Zealand, Australian coast, and the lands of New Caledonia. For the Tasman Sea, tides are not uncommon, and rather big: in some places they reach 5 m. The underwater world of these waters is very diverse, due to the geographical location of the sea: it is located immediately in three climatic zones. It also affects on water temperature: temperature difference in opposite parts Sea reaches 15-18 degrees.

The northern part of the sea is not particularly impressive with a variety of flora and fauna. But the water there is warm, the abundance of plankton attracts representatives of the tropics – sperm whales, flying fish, sailboats, whales etc. Tourists are offered many boat trips and interesting excursions to watch sharks and whales in the natural environment.

The climate in which the water area is located is quite severe: there are constantly low temperatures. On the surface of the sea in some parts of icebergs are found in places, and the bottom surface is densely covered with seaweed. There are many islands here, some of which are away from Australia and New Zealand. Among them are and one of the oldest volcanic islands on the planet – Lord Howe.

Far, cold and inhospitable, the Bering Sea for a long time remained unexplored. But that can’t stop the present researcher. The first serious attempts to study the waters of the sea were undertaken in the 18th century, but to this day not all are known secrets of its depths. Only two countries wash the Bering Sea – USA and Russia.

Interesting fact. In 2018, over the waters of the Bering Sea exploded large meteorite that entered the planet’s atmosphere.

The northern part of the sea is covered with a thickness of ice up to 9 months in year. Even in the summer season (in August) on the water icebergs are found, and the air temperature above the surface of the water rarely rises above 8-10 degrees heat. And although the Bering Sea cold, this does not mean that it is lifeless, although water there are fewer inhabitants than in warm seas.

Here, commercial fishing is carried out and many transport routes for ships, and not only Russian ones. The topics at least shipping at sea is dangerous, therefore not all year round. All because of the harsh climate.

The Bering Sea is known for dangerous and protracted storms that last sometimes longer than a week. This happens because of the constant collisions of warm waters of the Pacific and cold Arctic the ocean.

Like the Bering Sea, the Sea of ​​Okhotsk is also not very friendly. The weather here is severe, northern, and most of the year the waters are covered. the thickness of the ice, therefore, during this period of passage the vessels do not. Nevertheless many important economic navigational routes pass through these regions routes.

Interesting fact. The water of the Bering Sea and the ice with which it is covered sometimes glow, but to observe a similar phenomenon happened very few. Experts believe that this may be caused by dwelling in water with luminous plankton.

The coastal part of the Sea of ​​Okhotsk is considered slightly salted, which due to the large number of rivers flowing into it, including large ones.

In the winter period of 2010-2011, a large-scale rescue operation, which was spent about 200 million rubles and attracted several icebreakers. In an ice trap there were 15 vessels and 700 people on board. All was successful, with 11 of the 15 ships escaping from ice captivity yourself, breaking ice.

Only 2 countries – Russia have access to the Sea of ​​Okhotsk and Japan. But to fish and get useful fossils from the seabed only has the first. Although the Sea of ​​Okhotsk occupies only the 10th line in our rating, its size is still hit: the total length of the coastline is more than 10500 km. This is more than the length of Russia from west to east.
