The common name for the ocean that surrounds Antarctica is the Southern Ocean. This ocean is distinct for its unique characteristics, enclosed by the Antarctic landmass and characterized by cold waters. It plays a critical role in global climate regulation and ocean circulation, impacting marine ecosystems and weather patterns. The Southern Ocean supports diverse wildlife, including seals, penguins, and various fish species, making it crucial for ecological research and conservation efforts. Its remoteness and harsh conditions also highlight the importance of protecting this unique marine environment.
