The Great Southern Ocean is the body of water that encircles Antarctica, extending from the coast of the continent to the latitudes of 60 degrees south. It is the fourth-largest ocean, covering an area of about 21 million square kilometers. This ocean plays a crucial role in regulating the Earth's climate and is known for its unique marine ecosystems. Home to diverse wildlife, the Great Southern Ocean supports species such as seals, penguins, and various types of whales, including the humpback whale and the blue whale. The ocean is also vital for global ocean currents, particularly the Antarctic Circumpolar Current, which influences weather patterns worldwide.
