Researchers estimate the ancient offshore reserve holds enough freshwater to supply New York City for hundreds of years.

It sounds like something pulled from a science-fiction map. Beneath the Atlantic Ocean, hidden under layers of sediment, researchers have identified an enormous reserve of freshwater that has been sitting there for thousands of years.
The discovery didn’t come from drilling for water, but from data gathered for other scientific purposes. What scientists noticed forced them to reconsider what lies beneath continental shelves and how freshwater can survive offshore.
As estimates of the reservoir’s size emerged, the implications grew far larger than anyone expected. The find is changing how scientists think about hidden water resources and what might still be waiting beneath the ocean floor.
