The Southern Ocean As The World’s Fifth Ocean:
The National Geographic magazine has recognized the ‘Southern Ocean’ as the world’s fifth ocean.
- The Southern Ocean is the only ocean ‘to touch three other oceans and to completely embrace a continent rather than being embraced by them’.
- Its northern limit is a latitude of 60 degrees south.
- It is also defined by its Antarctic Circumpolar Current that was formed 34 million years ago. The current flows from west to east around Antarctica.
- The International Hydrographic Organization too had recognized the term in 1937 before repealing it in 1953.
