The answer is C. The Southern Ocean is also referred to as the Antarctic ocean. These waters are beyond latitude 60 degrees south and surround the Antarctic ocean. The ocean is only larger than the Arctic ocean. Some scientists do not recognize the Southern Ocean as an entity in its self but rather an extension of the Pacific, Atlantic, and Indian oceans. Proponents of the Southern Ocean refer to the significance circulation of waters in the southern latitudes to warrant it being named a separate ocean.
