Scientists found a freshwater aquifer under the ocean. And get this — there's enough water to fill 1.1 billion Olympic-sized swimming pools. 

Oceanographic teams have known for a while that there are pockets of fresh water below the seafloor. They would run into them occasionally when drilling offshore for oil but when geologists and geophysicists explored how big these pockets actually were, they were floored. 

Two different marine electromagnetic methods were used to pulse the seafloor. One involved deploying ten broadband electromagnetic receivers onto the actual seafloor, and the other involved towing an antennae that was broadcasting a certain frequency behind a ship with electromagnetic receivers at four different depth levels. 

Both of these techniques rely on the fact that salt water is a much better conductor of electromagnetic waves than fresh water, therefore allowing us to probe things we can't usually see...like the composition of the Earth below the seafloor.
