The ocean to the north of Antarctica is known as the Southern Ocean. It encircles the continent and is characterized by cold waters and strong currents. The Southern Ocean is significant for its unique marine ecosystems, supporting diverse species such as krill, seals, and various seabirds. It plays an important role in global climate regulation by influencing ocean circulation patterns. Additionally, the Southern Ocean is crucial for Antarctic research, providing insights into climate change and its impacts on polar regions. International agreements seek to protect this vital area and its wildlife.
