About Southern Ocean
- The Southern Ocean is the only ocean ‘to touch three other oceans (Pacific, Atlantic and Indian Ocean).
- It is the only Ocean to completely embrace a continent rather than being embraced by them.
- 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
Significance of Recognition
- It is a step towards conservation of World’s Oceans, redirecting public awareness onto a region which needs a conservation spotlight.
- Southern Ocean is getting rapidly warmed due to global warming, industrial fishing on species like krill and Patagonian tooth fish.
