What are black smoker vents?
OceanographyDeep sea
Quick Answer
Black smoker vents are hydrothermal vents that discharge dark, mineral-rich water from the deep ocean floor. The black color comes from metal sulfide particles that precipitate as the water cools.
The Full Story
Black smokers are usually found along mid-ocean ridges where tectonic plates are spreading apart. Their fluids can exceed 300°C at the vent opening, though the surrounding seawater is near freezing. The dark plume forms when dissolved metals like iron and sulfides rapidly crystallize. These vents can support dense communities of tube worms, clams, and shrimp that depend on bacteria living with them or on them.
