American  

noun

Oceanography, Geology.
  1. an opening on the floor of the sea from which hot, mineral-rich solutions issue.


hydrothermal vent Scientific  
  1. A fissure on the floor of a sea out of which flows water that has been heated by underlying magma. The water can be as hot as 400°C (752°F) and usually contains dissolved minerals that precipitate out of it upon contact with the colder seawater, building a stack of minerals, or chimney. Hydrothermal vents form an ecosystem for microbes and animals, such as tubeworms, giant clams, and blind shrimp, that can withstand the hostile environment.

  2. ◆ The hottest hydrothermal vents are called black smokers because they spew iron and sulfide which combine to form iron monosulfide, a black compound.
