World's Deepest Undersea Vents Found

Put it in the books: Scientists have discovered the deepest known undersea vents—a series of “black smokers” 3.1 miles down in the Caribbean Sea. The chimney-like structures give off mineral-rich water. The previously known deepest undersea vents were 2.6 miles deep. "It was like wandering across the surface of another world," said the geologist who piloted the vehicle that discovered the vents.
