World’s deepest undersea vents discovered

(LiveScience): Beneath the Caribbean Sea a remotely controlled vehicle came upon the world’s deepest hydrothermal vents, where super-heated mineral-rich water gushes from chimney structures onto the ocean floor. The black smokers, named for how they spew out an iron sulfide compound that’s black, sit 3.1 miles (5 kilometers) deep in the Cayman Trough in the Caribbean. While black smokers are the hottest of the undersea vents, white smokers are cooler and often contain compounds that are white in color. Until now, the deepest known vents had been found some 2.6 miles (4.2 km) below the sea surface.
