The Arctic Ocean is the smallest of the world's five ocean basins,
With an area of about 5.4 million square miles, the Arctic Ocean is about 1.5 times as big as the United States. It is bordered by Greenland, Canada, Norway, Alaska, and Russia. The average depth of the Arctic Ocean is 12,000 feet and it is 17,850 feet at its deepest point.
The Arctic Ocean is almost completely covered with ice for the majority of the year and its average temperature seldom rises above freezing. However, this ocean is anything but barren.
