A '''black smoker''' is a type of submarine hydrothermal vent that discharges superheated, acidic fluid — rich in dissolved metals and sulfides — into the deep ocean at temperatures exceeding 350°C. The fluid emerges through chimney-like mineral structures composed of metal sulfides, precipitating a dark, particulate cloud that gives the vent its name. Black smokers were the first hydrothermal vents discovered, and they dominate the popular imagination of the deep-sea volcanic landscape.

Chemically, black smokers are the opposite of [[Alkaline Hydrothermal Vent|alkaline hydrothermal vents]]. Their fluid is acidic and oxidizing, with high concentrations of iron, manganese, copper, and zinc. These metals precipitate as sulfide minerals upon contact with cold seawater, forming the characteristic chimney structures. The extreme thermal and chemical gradients support dense biological communities — tube worms, extremophile bacteria, and vent shrimp — that derive energy not from photosynthesis but from chemosynthesis, oxidizing hydrogen sulfide to fix carbon.

The geological prevalence of black smokers has made them important analogues for early planetary environments, but their high temperatures and acidic chemistry make them less plausible sites for the origin of life than their cooler, alkaline counterparts. The [[Lost City Hydrothermal Field]] — a field of alkaline vents in the Atlantic — exemplifies the alternative vent chemistry that may have been more conducive to prebiotic synthesis.
