Brazil-Malvinas Confluence


The southwestern Atlantic Ocean is characterized by the confluence of the Brazil and Malvinas Currents, which form very strong surface and subsurface fronts that can be detected from altimetry observations [1] [2] [3].

Brazil Current (BC) Variability

Latitude of separation of the BC front from the continental shelf and southernmost intrusion of the BC in the SW Atlantic.
