The smallest ocean in the world is the Arctic Ocean. Covering about 15.6 million square kilometers, it is located around the North Pole and bordered by Asia, North America, and Europe. The Arctic Ocean is unique due to its icy conditions and is the least studied among the world's oceans. Its shallow continental shelf and significant ice cover play a crucial role in global climate patterns and marine ecosystems. Its smaller size compared to the other four oceans results in it being often overlooked, yet it holds vital ecological importance and contains unique marine life adapted to its cold environment.
