Deep Sea Hydrothermal Vent

An underwater volcanic chimney spewing superheated mineral-rich water/Deep Sea & Ocean Life

Deep sea hydrothermal vents, also called black smokers, are underwater chimneys that form when superheated water (up to 400 degrees Celsius) erupts from the ocean floor at mid-ocean ridges. Despite water temperatures that would melt lead at surface pressure, the extreme pressure at 2,000+ meters depth keeps the water in a liquid state. The mineral-rich fluid supports thriving ecosystems of tube worms, crabs, and bacteria that derive energy from chemosynthesis rather than sunlight. These vents are considered one of the most plausible environments for the origin of life on Earth.
