The smallest ocean is the Arctic Ocean. It covers an area of approximately 15.6 million square kilometers, making it significantly smaller than the world's other oceans, such as the Pacific and Atlantic Oceans. The Arctic Ocean is located around the North Pole and is bordered by several countries, including Canada, Russia, and Norway. Its unique characteristics include being partially covered by sea ice and having a relatively low temperature. The Arctic Ocean plays a crucial role in regulating Earth's climate and is home to a variety of marine life, including seals, whales, and polar bears.
