Another Arctic Ocean Found Beneath Asia

May 12, 2007

Lots of water the size of the Arctic Ocean has been discovered hundreds of miles beneath eastern Asia, reports National Geographic. Researchers found the underground “Ocean” while scanning seismic waves as they passed through Earth’s interior.

Anyhow, I guess the fifth ocean is found though some consider it as a giant blob of water the point is that everything depends on the point of view.
