The vents at such sites are often referred to as black smokers because some emit hot, mineral-laden fluid that looks like dark, billowing smoke when it hits the icy cold seawater.

A black smoker is a rock tower shaped like a chimney.

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. Scientists are captivated. But so, too--much to the alarm of environmentalists--are mining companies

Cores taken from the black smoker chimneys tended to contain less anhydrite but more marcasite, sphalerite and chert, indicating lower temperature hydrothermal conditions.

Mid-Atlantic sulphide deposits

The key to the creation of black smoker chimneys is an unusual chemical property of the mineral anhydrite, or calcium sulfate (CaS[O.

The remarkable diversity of seafloor vents: continuing explorations reveal an increasing variety of hydrothermal systems

In 1988, on a cruise to the Juan de Fuca Ridge in the northeastern Pacific, Van Dover persuaded John Delaney of the University of Washington to take a picture of a black smoker vent with a charge-coupled device (CCD) camera while all of the submersible Alvin's external lights were turned off and the portholes blocked.

One of the most fascinating aspects of black smoker chimneys is how rapidly they form.

How to build a black smoker chimney

The power of the technique was most aptly demonstrated at the second site of the cruise, site 649, where the scientific party drilled next to an 11-meter-high black smoker.

They're not all big, they're not all the iconic black smokers, but they're places that likely support ecosystems, so there's way more places on the seafloor where animals can survive," Baker says.
