The entire body of water that surrounds Antarctica is known as the Southern Ocean. Also referred to as the Antarctic Ocean or the Austral Ocean, it is unique because it encircles the continent of Antarctica and distinguishes itself from the other oceans based on oceanographic criteria. The Southern Ocean is significant for its role in regulating global climate, as it aids in the transport of cold water and interacts with various currents. It is also home to a diverse array of marine life, including krill, seals, whales, and various fish species, all adapted to its cold and challenging environment.
