US Geological Survey (USGS) hydrologists drilling into the largest crater in the country have stumbled across an amazing discovery – the oldest body of seawater ever unearthed.
The water, which according to Discovery News is at least 100 million years old, was found over one kilometer beneath Chesapeake Bay in Virginia. The seawater is believed to have come from the earliest days of the Atlantic Ocean and was hidden beneath a more recent, 56-mile-wide impact crater near the bay’s entrance.
The USGS investigators did not realize how old the water was until they completed an analysis of the chemicals it contained. As it turns out, the water held forms of chloride and bromide, as well as other chemicals that helped them determine that the liquid is, in fact, from the Early Cretaceous Period. While older water has been discovered in Canada, the newly discovered crater is now officially the oldest large body of water on Earth.
