To create the simulation, the scientists tested their mini-oceans in the same temperature found near a hydrothermal vent (around 70 degrees Celsius) without any oxygen in the mixture (because Earth had very little oxygen in the ocean back then).
We measured routine metabolism in two hydrothermal vent gastropods, Alviniconcha marisindica (n = 40) and the scaly-foot gastropod Chrysomallon squamiferum (n = 18), from Kairei and Edmond vent fields on the Central Indian Ridge (23-25[degrees]S, about 3000 meter depth).
Scientists discovered this organism at a hydrothermal vent system near Okinawa, Japan, 3,000 feet below sea level.
Studies of the Fe isotope compositions of hydrothermal fluids from hydrothermal vent on the Pacific ridge [6,19], the Atlantic ridge [6, 18, 21], and the Juan de Fuca ridge [20] revealed that the Fe isotope compositions of these vent fluids varied significantly (Figure 2).
IN 1977, SCIENTIFIC researchers aboard a submarine dubbed Alvin descended down to the seafloor, where they observed a hydrothermal vent located off the Galapagos Islands.

dissertation in international law for Macquarie University, Australia (no date cited), Leary focuses on the sustainable management specifically of deep-sea hydrothermal vent ecosystems, and does not consider other ecosystems in the deep sea that are also subject to bioprospecting, though some of his discussion might apply in such contexts.
Peering through a 30 centimeter (12 inch) porthole, Humphris spied a hydrothermal vent. These springs on the seafloor spew out water that has been heated to searing temperatures by volcanic activity beneath Earth's surface.
