The ocean that surrounds the continent of Antarctica is called the Southern Ocean. This ocean, also known as the Antarctic Ocean, encircles Antarctica and is characterized by its cold waters and strong currents. It begins at the Antarctic Convergence, where cold polar water meets warmer ocean waters. The Southern Ocean plays a crucial role in Earth's climate regulation and is home to unique marine ecosystems, including species like krill, seals, and various penguin species. Its ecological significance is immense, influencing global ocean currents and weather patterns while being a critical area for research on climate change impacts.
