South Atlantic Gyre

In the southern portion of the gyre, northwesterly (or southeastward-flowing) winds drive eastward-flowing currents that are difficult to distinguish from the northern boundary of the Antarctic Circumpolar Current.

[1] Like other oceanic gyres, it collects vast amounts of floating debris as a garbage patch.

This current allows Antarctica to maintain its huge ice sheet by keeping warm ocean waters away.

It flows south along the Brazilian coast to the Rio de la Plata.

The current is considerably weaker than its North Atlantic counterpart, the Gulf Stream.
