Scientists discover sea of fresh water under the ocean – Quartz

Hundreds of years within the past, glaciers covered powerful of the planet. Oceans receded as water iced up in big sheets of ice blanketing the North American continent. As the ice age ended, glaciers melted. Huge river deltas flowed out at some level of the continental shelf. The oceans rose, and original water changed into as soon as trapped in sediments beneath the waves. Chanced on whereas drilling for oil offshore within the 1970s, scientists idea these “isolated” pockets of original water were a curiosity. Apart from they would possibly be able to as an different be aware to be a parched world’s most in type provide of original water.

As educated within the most modern issue (paywall) of the perceive-reviewed journal Scientific Experiences, scientists from Columbia University and the Woods Hole Oceanographic Institution spent 10 days on a study ship towing electromagnetic sensors from Fresh Jersey to Massachusetts. By measuring the sort electromagnetic waves traveled through original and saline water, researchers mapped out original-water reservoirs for the first time.

It turns out the subterranean pools stretch for as a minimum 50 miles off the US Atlantic flit, containing gigantic shops of low-salinity groundwater, about twice the quantity of Lake Ontario. The deposits delivery about 600 toes (183 m) beneath the seafloor and stretch for hundreds of miles. That opponents the scale of even basically the most attention-grabbing terrestrial aquifers.

“We knew there changed into as soon as original water down there in isolated locations, however we didn’t know the extent or geometry,” said lead writer Chloe Gustafson, a PhD candidate at Columbia University’s Lamont-Doherty Earth Observatory, in step with Phys.org. “It might most likely most likely also became a wanted helpful resource in assorted functions of the area.”

The scale and extent of the freshwater deposits suggest they are also being fed by in type-day runoff from land—and can exist in other locations with linked topography.

The water is now not any longer pure terrestrial original water, which incorporates salt concentrations of lower than one part per thousand. Attain land, the undersea aquifer has concentrations on the subject of pure original water. In direction of its edges, it can also attain 15 functions per thousand (about half of that of seawater). That’s serene precious. Desalination crops might perhaps also without problems turn that into drinkable water.
