In the Atlantic Ocean off the coast of Guyana and Suriname found two vortex diameter of 400 km, the newspaper La Stampa.
"In the Atlantic Ocean in front of the coast of the Amazon found two giant crater with a diameter of about 400 km. These are two huge whirlpools — none of these were not known on the planet. Has been suggested that they have a strong influence on the global climate changes of the past years" — the magazine writes.
"Funnels, found 200 km from the coast of Guyana, Suriname and French Guiana, it seems, are the result of the interaction of the flow coming from the north along the coast of northern Brazil, the South Equatorial Current, moving from the south, and the huge mouth of the Amazon." Funnels rotate clockwise direction, — said the Brazilian Guilherme Castellane, who has been studying these two huge mills with American Bill Jones of the University of Miami. — They are moving in the ocean like a giant "frisbee", two discs thrown into the air. Rotation occurs at a rate of 1 meter per second, the speed is sufficiently large compared to the speed of oceanic currents, on the border hoppers is a wave-step height of 40 cm. "
"Researchers have found that even in the months when the movement of ocean currents and the flow of the Amazon practically stops huge craters do not disappear." This suggests that there is some other type of independent mechanism that shapes them, "- said A study published by the American Geophysical Union. And this natural mechanism remains a mystery, "- writes the correspondent.
"Now we study the effect of these two giant whirlpools in the climate throughout Latin America and Africa. These hoppers can also have an impact on navigation between the northern and southern Atlantic." If ships were aware of sinkholes — Jones says — they could save fuel by using this very strong flow, "- says the correspondent of the newspaper.
