LONDON, Feb. 21 (UPI) -- British researchers say they have found a set of hydrothermal vents on the floor of the Caribbean Sea, the deepest yet found anywhere in the world.
A remotely-operated vehicle being used in the Cayman Trough, a deep trench formed at the boundary between two tectonic plates, found the 30-foot-tall vents belching superhot black water almost 16,500 feet below the ocean surface, the BBC reported Thursday.
