Hydrothermal vent temperature
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. When the superheated water contacts the near-freezing sea water, the minerals precipitate out to form particles which add to … Meer weergeven 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 … Meer weergeven Hydrothermal vents are distributed along the Earth's plate boundaries, although they may also be found at intra-plate locations such as hotspot volcanoes. As of 2009 there were approximately 500 known active submarine hydrothermal vent fields, with about … Meer weergeven Hydrothermal vents in the deep ocean typically form along the mid-ocean ridges, such as the East Pacific Rise and the Mid-Atlantic Ridge. These are locations where two tectonic plates are diverging and new crust is being formed. The water … Meer weergeven In 1949, a deep water survey reported anomalously hot brines in the central portion of the Red Sea. Later work in the 1960s confirmed the presence of hot, 60 °C (140 °F), saline brines and associated metalliferous muds. The hot solutions were … Meer weergeven Hydrothermal vents, in some instances, have led to the formation of exploitable mineral resources via deposition of seafloor massive sulfide deposits Meer weergeven

Web[10] On Earth, hydrothermal circulation in the oceanic crust accounts for approximately 50% of the total heat flux from cooling lithosphere less than 60 m.y. in age; at greater ages, thick sediment cover inhibits hydrothermal flux [Stein et al., 1995]. High-temperature ( 350 C) hydrothermal venting accounts for 3–15% of the total hydrothermal Web10 apr. 2024 · 1 Introduction. Seafloor hydrothermal venting along the mid-ocean ridges (MORs) emits enormous amounts of mass and energy into the global oceans (German & Seyfried, 2014; Hannington et al., 2005; Humphris et al., 1995; Petersen et al., 2024).There is growing evidence that the hydrothermal activity on MORs has responded to the …
