Southern Ocean The Southern Ocean is unique. Consistent eastward wind results in upwelling of the water from the interior of the ocean, providing a passage for the exchange between the atmosphere and deep ocean. Unlike other major ocean basins, it does not have boundaries so that water circulates all around Antarctica. This wind-driven current is called Antarctic Circumpolar Current (ACC) and flows eastward connecting Atlantic, Pacific and Indian Oceans. The Southern Ocean plays an important role in earth’s climate.
