Microbial essentials at hydrothermal vents
Nature, 2000Hot, anoxic fluids emerging from deep-sea hydrothermal vents mix suddenly with cold oxygenated sea water, providing ideal microbial niches for organisms that need limited amounts of oxygen. We have now identified and grown the first microaerophilic, thermophilic eubacterium from a deep-sea hydrothermal chimney.

Transient sounds of hydrothermal vents
The Journal of the Acoustical Society of America, 2023Transient acoustic signals were recently detected at the Main Endeavour Hydrothermal Vent Field which are believed to be generated by both geological and biological sources, including vent chimney collapse, impulsive geological signals, fish grunts, and snapping.

On the bottom of the oceans with volcanic activity present, hydrothermal vents can be found which spew out mineral rich superheated water from the porous seafloor crust.

Geomicrobiology of Deep-Sea Hydrothermal Vents
Science, 1985During the cycling of seawater through the earth's crust along the mid-ocean ridge system, geothermal energy is transferred into chemical energy in the form of reduced inorganic compounds. These compounds are derived from the reaction of seawater with crustal rocks at high temperatures and are emitted from warm (≤25°C) and hot (∼350°C) submarine vents ...

Hydrothermal plume simulation for autonomous hydrothermal vent discovery
2012 Oceans - Yeosu, 2012This paper presents a three dimension hydrothermal plume simulation model using Gaussian plume models to predict the mean plume concentration. The simulation model is to be used to evaluate the autonomous hydrothermal plume locating and mapping strategies.

Diversity at hydrothermal vents
Global Ecology and Biogeography, 2003ABSTRACTAimTo describe patterns of hydrothermal vent community diversity and dispersion at the intersegment scale (> 100 km).LocationThe area discussed is an approximately 170 km portion of the Juan de Fuca Ridge, a mid‐ocean ridge in the north‐east Pacific Ocean.MethodsSamples of benthic invertebrates from hydrothermal vents on three segments of ...

Hydrothermal Vent Fluids (Seafloor)
2014Hydrothermal vent fluid (seafloor): a hot (up to >400 C) aqueous solution discharging at the seafloor that typically originates from the reaction of seawater with oceanic crust under hightemperature high-pressure conditions, leading to enrichments in dissolved components such as metals and gases.

Geological indexes of hydrothermal venting
Journal of Geophysical Research: Solid Earth, 1996Hydrothermal venting occurs on mid‐ocean ridge axes with a diverse array of morphological, structural, and petrological characteristics. Consequently, it is not clear if certain geological environments are more conducive than others to hydrothermal activity.

Structure of Hydrothermal Vent Communities
2016Deep-sea hydrothermal vent communities are characterized by complicated taxonomic, trophic, and spatial structure. Different animals consume chemosynthetic bacterial production to a variable extent and by different ways. Different animal groups demonstrate variable degree of adaptations to the extreme environment of hydrothermal vent systems. According
