Hydrothermal Vent

View History

Hydrothermal Vents are heat-emitting geological structures found in deep underwater caves and biomes. They provide essential warmth for the player and host unique chemosynthetic ecosystems.

Thermal Vent

Hydrothermal Vents are heat-emitting structures found deep underground, primarily in icy or deep-sea environments. They produce significant heat that the player can use to warm up when suffering from hypothermia.

Databank Entry

650px-Thermal Vent Ency

Hydrothermal vents are created when water filters through cracks in the planetary crust and ultimately collides with hot magma. As a result, superheated water is propelled upwards, bursting through the ocean floor.

The water temperature at the vent opening was once hot enough to melt lead; the application of temperature and pressure over time resulted in the emerging rock structure.

Despite the intense temperatures, these vents are home to their own ecosystems of life. At the bottom of the food chain, chemosynthetic microorganisms are found - lifeforms that feed off of the vent’s chemical emissions.
