The Sargasso Sea

The Sargasso Sea occupies large expanses of the Atlantic Ocean, closer to the mainland of North America. It is a miracle of nature, with coasts not of land, but large oceanic currents: in the west and north - the North Atlantic, in the east - the Canary, in the south - the Passat, which move in a circular fashion clockwise and do not give the surface waters of the Sargasso Sea to mix with more cold waters of the North Atlantic.

Interestingly, the water "coast" because of the impermanence of the sea currents undergo significant movements, that is, "travel". Therefore, the area of the Sargasso Sea varies from 8,5 to 4 million square km.

Like a giant meadow, the Sargasso Sea is covered with a huge number of floating one species of seaweed, which is no longer anywhere else in the world. One square kilometer of the sea surface accounts for one to two tons! Christopher Columbus, who discovered the Sargasso Sea on September 16, 1492, called it "a can of algae". These algae, which are born here, live and die, stay on the water thanks to air bubbles. When the plants die, the vesicles burst, and the burnt algae sink in the ocean depths.

Sargasso algae, like the forest, are densely populated with different livestock: shrimps, crabs, numerous species of fish and about 60 species of flora and fauna. Sargasso Sea is unique because it is the cradle of freshwater fish-eels. Sailing in summer to spawn from the rivers of Europe and America, they die after its termination, and their descendants, using some mysterious, only known landmarks, overcoming many thousands of kilometers, return exactly to the places where their parents sailed, that in 8-9 years again to come back here, sweep away caviar and die.

The Sargasso Sea is poor in plankton, and therefore very transparent. Due to the insignificant movement, the water in the sea is more salty than the surrounding oceanic one. It is bright blue and one of the most transparent in comparison with the water of all seas. The water temperature is also higher here than in the ocean and ranges from 18-230 C to 21-280 C.

The Sargasso Sea reaches a depth of 4-7 km. It is located in the zone of elevated atmospheric pressure, because here the calm prevails, which in the era of sailing fleet often led to the death of ships. For the prevalence of calm weather, the sea was called "ladies", and for a large number of algae - "grassy".

However, the Sargasso Sea seems at first sight to be calm. Oceanographers have discovered powerful upward movements of water from great depths, the so-called whirlwinds. It is established that they affect the rise and fall of sea water temperatures.
