Arctic Ocean


The Arctic Ocean is the smallest in the world’s five major oceans. It covers an area of 5,427,000 square miles which is less than 3% of the earth’s surface. It is also the shallowest of all of them. It is Earth’s northernmost body of water. It encircles the Arctic, and flows beneath it.

Most part of it remains covered in ice and the thickness of ice can vary depending on the season. This ocean’s name has been derived from the word ‘arktos’ which means ‘bear’ in Greek.
