The only mystery about the sea is not in the world

In the past, many horse-boats used to be stuck in Sargasso Sea for weeks, causing sailors to throw down horses.

Sargasso , located in the North Atlantic Ocean, is the only sea area on Earth that has no shore. Although accounting for two-thirds of the Atlantic Ocean, this strange water is covered by . the sea itself, not the mainland.

Unlike other oceans, Sargasso is not formed in the lands around it, but by the four ocean currents in the Subtropical Flow: the Gulf Stream, the North Atlantic, and the Canary and the North Atlantic equatorial line. These currents circulate in an elliptical shape clockwise inside the Atlantic Ocean and help establish the constantly changing boundaries of the Sargasso Sea.

With 1,600km of width and 4,800km of length, this vast sea is named from a seaweed genus called Sargassum . Sargassum is a free floating brown algae on the water surface. It has a unique characteristic that instead of living on the seabed, it produces right on the water. Because Sargassum is often driven by currents and winds, it is like a migratory creature in a diverse marine ecosystem.

Not only is the shelter of shrimp, crab and fish, this floating algae is also a gathering place for herds of young turtles and rare eel species. Each year, large marine creatures like humpback whales, sharks and birds migrate into the Sargasso Sea, scouring the floating seaweed for prey.

Those who want to enter the Sargasso Sea will have to be careful with the North Atlantic Garbage Patch. The island is formed when waste is trapped between Sargasso's currents, with an amount of 200,000 pieces of waste per km ² . Their composition is mainly microplastic particles, smaller than a tenth of the size of a paper clip, blown by the wind from the landfills and thrown into the sea by humans.

There was a time when the Sargasso Sea was nicknamed the Horse Latitudes . This name was formed because there were many horse boats stuck here for weeks, forcing the crew to throw them down into the sea to reduce the load. The explorers at the time believed that this incident was caused by dense Sargassum algae, but so far it has not been proven. Now, the sea surface is calm and there is no strong wind that is supposed to cause boats to move slowly in this sea.
