Searching for unknown life at the bottom of the sea: a largely unexplored region could harbor organisms we've never seen before

Black smokers, or deep-sea hydrothermal vents, are present in all of the world's oceans in areas associated with tectonic and volcanic activity.

Where there's smoke, there's gold: it sounds like something from a tale by Jules Verne: deep-sea volcanoes that belch out black 'smoke' into a strange world inhabited by outlandish creatures and strewn with precious minerals.

Exactly what relationship black smoker chimneys have with volcanoes creating new oceanic crust is still uncertain but most scientists now agree that they probably exist throughout the Ridge system.

Mid-Atlantic sulphide deposits

When the clear hot fluid jetting from these chimney-like structures mixed with cold seawater, fine particles of dark metal sulfides precipitated out of solution, creating the appearance of black "smoke" (hence the name "black smoker chimneys.")
