Where frigid waters around the Antarctic meet warmer of Atlantic Pacific and Indian oceans?

The Antarctic Convergence, also known as the Antarctic Polar Front, is the boundary between the cold, nutrient-rich waters of the Southern Ocean and the warmer, less nutrient-rich waters of the Atlantic, Pacific, and Indian oceans. It is a dynamic zone of great ecological significance, where the mixing of waters creates a highly productive ecosystem that supports a diverse range of marine life.
