WebHydrothermal Floor Vents Christian Kaiser Hydrothermal vents are found near mid ocean ridges, divergent plate boundaries, where tectonic plates are moving apart. They are usually more than 2000 meters below the ocean's surface. These vents are formed when lava spews from an underground volcano and mixes with the cold ocean water. The cold … Life has traditionally been seen as driven by energy from the sun, but deep-sea organisms have no access to sunlight, so biological communities around hydrothermal vents must depend on nutrients found in the dusty chemical deposits and hydrothermal fluids in which they live. Previously, Benthic oceanographers assumed that vent organisms were dependent on marine snow, as deep-sea organisms are. This would leave them dependent on plant life and thus the sun. …
