Southern Ocean

The Southern Ocean comprises the southernmost waters of the World Ocean, generally taken to be south of 60°S latitude and encircling Antarctica. As such, it is regarded as the fourth-largest of the five principal oceanic divisions (after the Pacific, Atlantic, and Indian Oceans, but larger than the Arctic Ocean). This ocean zone is where cold, northward flowing waters from the Antarctic mix with warmer subantarctic waters.

Marvel Comics
In the continuity of the Marvel Universe, the Southern Ocean is where part of the sunken kingdom of Atlantis is located. In 1920, an American icebreaker ship known as the Oracle was moving through the Southern Ocean en route towards the South Pole. To clear a path through the ice, it began dropping depth charges, unwittingly destroying large areas of the undersea kingdom. At the time, the Atlanteans did not have a suitable military by which to defend themselves, but over the next two decades, they began marshalling their forces, preparing for the day when they would be able to wage war against the surface world.
