The Arctic Ocean is the smallest and shallowest of the world's five major oceans, located around the North Pole. It is bordered by several countries, including Canada, Russia, and Norway, and is known for its unique ecosystem and ice-covered waters. This ocean plays a crucial role in regulating the Earth's climate and is home to diverse marine life, such as polar bears, seals, and various fish species. As climate change continues to impact the Arctic region, the Arctic Ocean is experiencing significant changes, including melting ice and shifting habitats.
