According to a news release from Flinders University, researchers have found massive reserves of freshwater beneath oceans, offering new chances to prevent an emerging global water crisis. They discovered that approximately 500,000 cubic km of low-salinity water are hidden beneath the seabed on continental shelves around the globe.
The water has been found off Australia, China, North America and South Africa.
The volume of this water resource is a hundred times greater than the amount weve extracted from the Earths sub-surface in the past century since 1900, noted lead author Vincent Post of the National Centre for Groundwater Research and Training and the School of the Environment at Flinders University. Knowing about these reserves is great news because this volume of water could sustain some regions for decades.
According to Post, groundwater scientists previously believed that freshwater under the seafloor only took place under special conditions, but the new research reveals that freshwater aquifers beneath the oceans are actually commonplace.

(2,347 posts)but I will, but the reason it's mind-boggling is simple: salt water bodies of water are salt water because they have no outlet. The Dead Sea is dead for that reason, for instance. Oceans, obviously, have no outlet. Thus, salt water. Finding fresh water UNDER that salt water is definitely weird. Good, but weird.

When the sea levels rose approximately 20,000 years ago, the freshwater aquifers were shielded from salty seawater by layers of clay and sediment that are positioned on top of them.div class=
