Güney Okyanusu, also known as the Southern Ocean, is the body of water that encircles Antarctica. It is recognized as the fourth largest ocean, covering an area of about 21 million square kilometers. The ocean plays a crucial role in regulating the Earth's climate and is home to unique marine life, including species like the Emperor penguin and various types of krill. The Güney Okyanusu is characterized by its cold temperatures and strong currents, particularly the Antarctic Circumpolar Current. This current helps to connect the Atlantic, Pacific, and Indian Oceans, facilitating the movement of water and nutrients. The ocean is also significant for scientific research, particularly in studies related to climate change and marine ecosystems.
