Scientists Discover Massive Freshwater Reserves Underneath The Ocean Floor

Australian researchers said Thursday they had established the existence of vast freshwater reserves trapped beneath the ocean floor which could sustain future generations as current sources dwindle.

Lead author Vincent Post, from Australia's Flinders University, said that an estimated 500,000 cubic kilometres (120,000 cubic miles) of low-salinity water had been found buried beneath the seabed on continental shelves off Australia, China, North America and South Africa.

"The volume of this water resource is a hundred times greater than the amount we've extracted from the Earth's sub-surface in the past century since 1900," said Post of the study, published in the latest edition of Nature.

"Freshwater on our planet is increasingly under stress and strain so the discovery of significant new stores off the coast is very exciting.

"It means that more options can be considered to help reduce the impact of droughts and continental water shortages."
