The smallest ocean on Earth is the Arctic Ocean. Covering an area of about 15 million square kilometers, it is located around the North Pole and bordered by several countries, including the United States, Canada, Russia, and Norway. The Arctic Ocean is characterized by its cold temperatures, sea ice cover, and unique marine ecosystems. It plays a critical role in the global climate system and acts as a habitat for various species, including polar bears, seals, and numerous fish. Despite its small size compared to other oceans, the Arctic Ocean significantly influences weather patterns and ocean currents worldwide.
