The ocean surrounding the continent of Antarctica is called the Southern Ocean. It is sometimes referred to as the Antarctic Ocean and is the fourth-largest ocean in the world, encircling Antarctica and connecting with the Atlantic, Pacific, and Indian Oceans. The Southern Ocean is known for its distinct ecosystem, featuring unique species such as emperor penguins, seal populations, and various forms of marine life adapted to its cold waters. It plays a vital role in regulating the Earth's climate by affecting ocean currents and temperatures. This ocean is also critical for scientific research related to climate change and biodiversity.
