Vast hidden ‘ocean’ found under Chinese desert

By

Chinese scientists have discovered what could be a huge hidden ocean underneath one of the driest places on earth, the South China Morning Post reported on 30 July.

The Tarim basin in northwestern Xinjiang, China, is one of the driest places on Earth, but the vast amount of salt water concealed underneath could equal 10 times the water found in all five of theGreat Lakes in the US.

“This is a terrifying amount of water,” said professor Li Yan, who led the study at the Chinese Academy of Sciences’ Xinjiang Institute of Ecology and Geography in Urumqi, the Xinjiang capital.

“Never before have people dared to imagine so much water under the sand. Our definition of desert may have to change,” he told the South China Morning Post.

Scientists had long suspected that a vast amount of melt water from nearby mountains had slipped beneath the basin, but the exact amount of water remained unknown.

Accidental discovery

Li’s team made the discovery by accident. They had actually been looking for carbon dioxide, which is absorbed in certain areas – such as forests and oceans – called “carbon sinks.”

Scientists study carbon sinks to gain a greater understanding of climate change.

Around 10 years ago, the team discovered that carbon dioxide had been disappearing into the basin for 10 years, but could not understand why.
