SOUTHAMPTON, England, Feb. 14 (UPI) -- British researchers say the discovery of deep-sea volcanic vents in the Antarctic's Southern Ocean suggests they're more common than previously thought.

Deep-sea vents are hot springs on the seafloor, where mineral-rich water nourishes colonies of microbes and animals.

Around 250 such vents have been discovered worldwide in the three decades since scientists first encountered them in the Pacific. Most have been found on a chain of undersea volcanoes called the mid-ocean ridge but very few are known in the Antarctic, a release from the U.K. National Oceanography Center said Monday.
