The critical point of seawater (3.2 wt. % NaCl) is 407 °C (765 °F) and 298.5 bars, [8] corresponding to a depth of ~2,960 m (9,710 ft) below sea level. Accordingly, if a hydrothermal fluid with a salinity of 3.2 wt. % NaCl vents above 407 °C (765 °F) and 298.5 bars, it is supercritical. Meer weergeven A hydrothermal vent is a fissure on the seabed from which geothermally heated water discharges. They are commonly found near volcanically active places, areas where tectonic plates are moving apart at mid-ocean ridges Meer weergeven Some hydrothermal vents form roughly cylindrical chimney structures. These form from minerals that are dissolved in the vent fluid.

Web10 dec. 2024 · To date, around 50 marine shallow water hydrothermal systems, generally at a water depth less than 200 m, have been discovered. These systems reflect regional fluid–rock interaction, magma degassing, the release of heat, and vigorous elemental reactions. Further, shallow water hydrothermal vent ecosystems are distinctly different … Web22 jul. 2024 · The vents which create black smokers tend to be hotter, anoxic, acidic and sulfurous [8], producing the characteristic black color and structures that can reach as high as 180 feet. By contrast, the vents which produce the sibling of the black smokers, the white smokers, tend to have cooler plumes rich in barium, calcium, and silicon [6].
