The World Ocean, world ocean, or global ocean is a term used to define all the world’s oceans as one big ocean.

It is divided into five oceans. These divisions are the Atlantic Ocean, Arctic Ocean, Indian Ocean, Pacific Ocean, and Southern Ocean.

• The Southern Ocean is the ocean surrounding Antarctica, generally the ocean south of sixty degrees south latitude. Parts of the Southern Ocean are covered in sea ice. The Southern Ocean is the second smallest of the five named oceans.
• The Atlantic Ocean, the second biggest, extends from the Southern Ocean to the Arctic Ocean between South America, Africa, North America, and Europe.
• The Indian Ocean extends northward from the Southern Ocean to India, between Africa and Australia. The Indian Ocean joins the Pacific Ocean to the west, near Australia.
• The Pacific Ocean, the biggest of all, also reaches northward from the Southern Ocean to the Arctic Ocean. It is in the gap between Australia, Asia, North America, and Oceania.
• The Arctic Ocean is the smallest of the five. It joins the Atlantic near Greenland and Iceland and joins the Pacific at the Bering Strait. It is on the North Pole. Parts of the Arctic Ocean are covered in sea ice.
