What is a black smoker?
Quick Answer
A black smoker is a type of hydrothermal vent that releases dark, mineral-laden fluid, creating a chimney-like structure on the seafloor.
The Full Story
Black smokers form when superheated vent water mixes with cold seawater and minerals such as iron and sulfides precipitate out, giving the plume its dark appearance. These vents are typically found along mid-ocean ridges where new ocean crust is forming. The chimneys can grow and collapse as mineral deposits build up, sometimes reaching several meters in height. Black smokers are famous because they host dense communities of vent organisms that survive in complete darkness.
