Scientists discover the sea of fresh water under the ocean – Quartz
Thousands of years ago, the glaciers covered much of the planet. Oceans receded as water froze in massive sheets of ice blanketing the North American continent. As the ice age ended, the glaciers melted. Massive river deltas flowed out across the continental shelf. The oceans rose, and fresh water was trapped in the sediments below the waves. Discovered while drilling for oil offshore in the 1970s, scientists thought these "isolated" pockets of fresh water were a curiosity.
As mentioned in the latest issue (paywall) of the peer-reviewed journal Scientific Reports, scientists from Columbia University and the Woods Hole Oceanographic Institution spent 1
0 days on and research ship towing electromagnetic sensors from New Jersey to Massachusetts. By measuring the way electromagnetic waves traveled through fresh and saline water, researchers mapped out fresh-water reservoirs for the first time.
It turns out the underground pools stretch for at least 50 miles off the US Atlantic coast, containing vast stores of low-salinity groundwater, about twice the volume of Lake Ontario. The deposits begin about 600 ft (183 m) below the seafloor and stretch for hundreds of miles. That rivals the size of even the largest terrestrial aquifers
