  • Hydrothermal vents in the deep sea

    In many areas of high volcanic activity, water seeps into the sub-surface where it is intensely heated and then finds its way to the surface again. Examples on the land include hot springs in therapeutic spas, and special types like geysers and fumaroles. In the ocean, this circulation occurs most commonly at the mid-ocean ridge, the world's longest mountain chain. Here, far below the depth of sunlight penetration, hydrothermal vents at over 400°C with their dissolved compounds provide the basis for complex ecosystems.

    Since being discovered in 1977, Hydrothermal Vents have been a source of huge interest, due to their rich diversity and huge populations of new and specialised species in a comparatively baron and homogenous abyss. The mineral rich chimneys spew out a sulphurous fluid which forms an energy source for microbes, forming the base of these fascinating and unique ecosystems. Their isolation and mysterious interconnectivity reveals a fragile web of life that still has so much more left to be fully appreciated. The vents have also caught the attention of deep-sea mining contractors. 30 years on from their initial discovery, the global population has doubled and commodity prices have increased. Now, with new technological advances, deep-sea mining has become an imminent reality. Specialist resea...

    During a recent expedition to the Gulf of California scientists from MBARI discovered a new field of hydrothermal vents, the deepest yet discovered in the Gulf of California. These new hydrothermal vent fields were found over thirty-eight hundred meters below the surface in the Pescadero Basin, located off the east coast of Mexico’s Baja California, about one hundred miles east of La Paz. These hydrothermal vents result from a unique combination of geology and chemistry. Using a remotely operated vehicle, researchers found towering white columns emitting geysers of clear shimmering liquid with temperatures up to 290 degrees Celsius. The superheated water flowing from these vents starts deep underground. As the hot water rises, it flows through and reacts with the surrounding bedrock, becom...

    On the ninth remotely operated vehicle (ROV) dive of the Galapágos Rift 2011 expedition on NOAA Ship Okeanos Explorer, the science team finally discovered the type of hydrothermal vent community they had been searching for. Clusters of tube worms, limpets, mussels, and anemones were seen to inhabit cracks in the lava bed where mineral-rich, geothermally heated water 'vents' out. Two species of tube worms were found in abundance: the giant Riftia pachyptila and also the much smaller, never observed in the Galápagos, Tevnia jerichonana. Brachyuran crabs, vent shrimp, and scale worms clung not only to the surrounding rock but also to the tube worms themselves in some cases. Extensive fields of dead and living clams surrounded the individual pockets of venting. Video courtesy of NOAA Okea...

    Lecture by Dr Adrian Glover given at the Geological Society on 3 July 2013 as part of the 2013 Shell London Lecture series. It is an oft-told tale that the most famous biological discovery of the late 20th century was made by geologists. In the spring of 1977, a cabal of bearded American oceanographers made the first daring submersible dives to a deep-sea hydrothermal vent in the east Pacific ocean and filmed, photographed and collected the biology that would make them famous. But it was no ignominy for the biology community; uninvited on that first expedition they went on to lead the majority of research at vents over the next three decades. Over 35 years on, it is the geology which may now turn attention back to the deep sea. In 2011 the government of Papua New Guinea granted the world...

Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. A hydrothermal vent is a fissure in a planet's surface from which geothermally heated water issues. Hydrothermal vents are commonly found near volcanically active places, areas where tectonic plates are moving apart, ocean basins, and hotspots. Hydrothermal vents exist because the earth is both geologically active and has large amounts of water on its surface and within its crust. Common land types include hot springs, fumaroles and geysers. Under the sea, hydrothermal vents may form features called black smokers. Relative to the majority ...

In the spring of 1977, a cabal of bearded American oceanographers made the first daring submersible dives to a deep-sea hydrothermal vent in the east Pacific ocean and filmed, photographed and collected the biology that would make them famous. But it was no ignominy for the biology community; uninvited on that first expedition they went on to lead the majority of research at vents over the next three decades. Over 35 years on, it is the geology which may now turn attention back to the deep sea. In 2011 the government of Papua New Guinea granted the world's first deep-sea mining lease to a Canadian corporation to extract copper and gold from a hydrothermal vent field. In March 2013, the UK Prime Minister announced UK government support for the mining of polymetallic nodules in the central Pacific ocean at depths of 4000m. This talk summarises our current understanding of biodiversity at deep-sea hydrothermal vents, and compares it with the soft-sediment, muddy habitats that dominate the rest of the deep seafloor. Dr Adrian discusses the potential impacts of deep-sea mining and the importance of biological data and outlines some of the very newest results from an expedition this year to the Cayman Trough, the worlds deepest hydrothermal vent, that lies in an exclusive economic zone of the United Kingdom.

What is HYDROTHERMAL VENT? What does HYDROTHERMAL VENT mean? HYDROTHERMAL VENT meaning - HYDROTHERMAL VENT definition - HYDROTHERMAL VENT explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. A hydrothermal vent is a fissure in a planet's surface from which geothermally heated water issues. Hydrothermal vents are commonly found near volcanically active places, areas where tectonic plates are moving apart, ocean basins, and hotspots. Hydrothermal vents exist because the earth is both geologically active and has large amounts of water on its surface and within its crust. Common land types include hot springs, fumaroles and geysers. Under the sea, hydrothermal vents may form features called black smokers. Relative to the majority of the deep sea, the areas around submarine hydrothermal vents are biologically more productive, often hosting complex communities fueled by the chemicals dissolved in the vent fluids. Chemosynthetic bacteria and archaea form the base of the food chain, supporting diverse organisms, including giant tube worms, clams, limpets and shrimp. Active hydrothermal vents are believed to exist on Jupiter's moon Europa, and Saturn's moon Enceladus, and it is speculated that ancient hydrothermal vents once existed on Mars. 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 that issues from seafloor hydrothermal vents consists mostly of sea water drawn into the hydrothermal system close to the volcanic edifice through faults and porous sediments or volcanic strata, plus some magmatic water released by the upwelling magma. In terrestrial hydrothermal systems, the majority of water circulated within the fumarole and geyser systems is meteoric water plus ground water that has percolated down into the thermal system from the surface, but it also commonly contains some portion of metamorphic water, magmatic water, and sedimentary formational brine that is released by the magma. The proportion of each varies from location to location. In contrast to the approximately 2 °C ambient water temperature at these depths, water emerges from these vents at temperatures ranging from 60 to as high as 464 °C. Due to the high hydrostatic pressure at these depths, water may exist in either its liquid form or as a supercritical fluid at such temperatures. The critical point of (pure) water is 375 °C at a pressure of 218 atmospheres. However, introducing salinity into the fluid raises the critical point to higher temperatures and pressures. The critical point of seawater (3.2 wt. % NaCl) is 407 °C and 298.5 bars, corresponding to a depth of ~2960 m below sea level. Accordingly, if a hydrothermal fluid with a salinity of 3.2 wt. % NaCl vents above 407 °C and 298.5 bars, it is supercritical. Furthermore, the salinity of vent fluids have been shown to vary widely due to phase separation in the crust. The critical point for lower salinity fluids is at lower temperature and pressure conditions than that for seawater, but higher than that for pure water. For example, a vent fluid with a 2.24 wt. % NaCl salinity has the critical point at 400 °C and 280.5 bars. Thus, water emerging from the hottest parts of some hydrothermal vents can be a supercritical fluid, possessing physical properties between those of a gas and those of a liquid. Examples of supercritical venting are found at several sites. Sister Peak (Comfortless Cove Hydrothermal Field, 4°48'S 12°22'W, elevation -2996 m) vents low salinity phase-separated, vapor-type fluids. Sustained venting was not found to be supercritical but a brief injection of 464 °C was well above supercritical conditions. A nearby site, Turtle Pits, was found to vent low salinity fluid at 407 °C, which is above the critical point of the fluid at that salinity. A vent site in the Cayman Trough named Beebe, which is the world's deepest known hydrothermal site at ~5000 m below sea level, has shown sustained supercritical venting at 401 °C and 2.3 wt% NaCl. Although supercritical conditions have been observed at several sites, it is not yet known what significance, if any, supercritical venting has in terms of hydrothermal circulation, mineral deposit formation, geochemical fluxes or biological activity.

Hydrothermal vents found on the East Pacific Rise continuously spew hot, mineral-rich water that helps support a diverse community of organisms, including the giant tube worm, Riftia pachyptila. These tube worms have a symbiotic relationship with bacteria that obtain nutrition from the vent fluids.
