Southern Ocean

The Southern Ocean, also known as the Antarctic Ocean  or the Austral Ocean.

                In 2000, the International Hydrographic Organization created the fifth and newest world ocean — the Southern Ocean — from the southern portions of the Atlantic Ocean, Indian Ocean, and the Pacific Ocean. The new Southern Ocean completely surrounds Antarctica.​

           The Southern Ocean extends from the coast of Antarctica north to 60 degrees south latitude. The Southern Ocean is now the fourth largest of the world's five oceans.

             For some time, those in geographic circles have debated whether there are four or five oceans on Earth.

         

 Some consider the Arctic, Atlantic, Indian, and Pacific to be the world's four oceans. Now, those that side with the number five can add the fifth new ocean and call it the Southern Ocean or the Antarctic Ocean, thanks to the International Hydrographic Organization (IHO).
