The smallest ocean in the world is the Arctic Ocean, which covers an area of about 15 million square kilometers (5.8 million square miles). It is located around the North Pole and is bordered by Canada, Alaska, Greenland, Norway, and Russia. Characterized by its icy waters and unique ecosystem, the Arctic Ocean plays a vital role in Earth's climate and ocean currents. Despite its small size compared to other oceans, it hosts diverse marine life adapted to extreme cold. Furthermore, the Arctic region is of increasing interest due to climate change, resource exploration, and geopolitical considerations.
