What is the deepest known hydrothermal vent field?

The Beebe Hydrothermal Vent Field, also known as the Piccard Vent Field, is the world's deepest known hydrothermal vent site. Located in the Caribbean's Cayman Trough, it sits nearly 5,000 meters below sea level in the abyssopelagic zone. Its extreme depth and high temperatures make it a key location for studying high-pressure biology, geochemistry, and aqueous thermodynamics.

What we know

• The Beebe Hydrothermal Vent Field is the world's deepest known hydrothermal vent site and is also known as the Piccard Vent Field. [1, 2]
• It is located just south of Grand Cayman in the Caribbean, on the north side of the Mid-Cayman Spreading Centre in the Cayman Trough. [2]
• At nearly 5,000 meters below sea level, it is situated in the abyssopelagic zone. [2, 5]
• The hydrothermal plume for the site, nicknamed Piccard, was detected in 2010 and confirmed later that year. [2]
