Arctic Ocean

The Arctic Ocean is the smallest and shallowest of the world's five major oceans. It is located in the Northern Hemisphere and is almost completely surrounded by Eurasia and North America. The Arctic Ocean is covered by sea ice throughout much of the year, with the ice reaching its maximum extent during the winter months.

Key Facts

• Location: The Arctic Ocean is located in the Northern Hemisphere, mostly north of the Arctic Circle.
• Size: The Arctic Ocean covers an area of about 14 million square kilometers, making it the smallest of the world's oceans.
• Depth: The average depth of the Arctic Ocean is about 1,038 meters, with the deepest point being the Eurasian Basin at 5,450 meters.
• Sea Ice: The Arctic Ocean is covered by sea ice, which reaches its maximum extent in the winter months and shrinks during the summer.
• Wildlife: The Arctic Ocean is home to a variety of marine life, including polar bears, seals, whales, and numerous species of fish and birds.
