Researchers discover massive freshwater reserves under the ocean

We all know that you can’t drink saltwater without removing the salt. In many parts of the world, clean fresh water is hard to come by. People drill deep wells, but at times, there is no water to be found. A group of researchers has discovered huge reserves of fresh water under the oceans.

It sounds strange to find freshwater under the salty ocean depths. However, researchers claim to have found 500,000 cubic km of low-salinity water hidden beneath the seabed on the continental shelves around the globe.

The scientists claim that the fresh water has been discovered off Australia, China, North America, and South Africa. According to one of the researchers that discovered the fresh water, the volume of water found is a hundred times greater than the volume of water extracted from the sub-surface of the Earth since 1900.

Previously it was believed that freshwater aquifers under the seafloor only happened under special circumstances. The new research suggests that fresh water is common under the seafloor. The team says that these massive freshwater reserves were developed over hundreds of thousands of years when the average sea level was much lower than it is now. The freshwater was shielded from the salty ocean water by layers of clay and sediment.
