Brazil–Malvinas Confluence

E44572

oceanic frontal system oceanographic region

The Brazil–Malvinas Confluence is a major oceanographic region in the South Atlantic where warm subtropical waters meet cold subantarctic waters, creating one of the most energetic and biologically productive frontal systems in the world.
