Where is the Southern Ocean located?

The Southern Ocean is located above Antarctica, marking the waters that encircle the continent. This ocean is significant because it plays a critical role in the global climate system and acts as a key area for oceanic currents which influence weather patterns globally. The Southern Ocean is often defined by the Antarctic Circumpolar Current, which flows around Antarctica and connects the Atlantic, Pacific, and Indian Oceans. This ocean is unique in its ecosystem, which is adapted to colder water temperatures and is home to various species, including Antarctic krill and seal populations.

In contrast, the other choices erroneously identify the locations of various oceans or continental regions. The Southern Ocean does not extend below Australia, surround the Arctic region, or enclose the continent of Africa, as those references relate to different geographical bodies and seas. Understanding the correct positioning of the Southern Ocean is essential for comprehending its environmental and climatic significance.
