What Is the Ocean Surrounding Antarctica Called?

The waters encircling Antarctica are designated the Southern Ocean (also known as the Antarctic Ocean). Recognized as the world's fifth ocean, it extends north to about 60°S latitude, separating the Antarctic continent from the Atlantic, Pacific, and Indian Oceans. The Southern Ocean is defined by the powerful Antarctic Circumpolar Current, frigid temperatures, and unique ecosystems that play a pivotal role in global climate regulation and carbon sequestration.
