[Webster 1913 Suppl.]
black smoker, a vent at the bottom of the ocean, usually at
a mid-ocean ridge, through which large quantities of water
carrying minerals flow, producing a jet of fluid with the
appearance of black smoke. The ocean water in crevices
below the vent is heated to temperatures near 400[deg] C,
and dissolves quantities of metal salts, such as of
copper, zinc, gold, and manganese. When the saturated
mineral solutions exit the vent, cooling by contact with
the ocean causes the metals to precipitate, mainly as
sulfide or sulfate salts. Unusual forms of life such as
tube worms have been found to live in the areas near
black smokers. Additional information is available from [a
