hydrothermal vent

n.
A fissure on the floor of a sea from which flows mineral-rich water that has been heated by underlying magma, forming a precipitate of minerals and providing an ecosystem for extremophiles.

This body of work describes a crab species that shares fundamental biological characteristics with typical shallow-water brachyuran crabs, yet possesses a suite of highly evolved traits specific for life at hydrothermal vents. Bythograea thermydron is one of only six known species of By thograea and is very abundant at vent sites along the East Pacific Rise.
"Cassini has given us a glimpse beneath the ice of Enceladus and it is genuinely fascinating in a scientific sense because many biologists believe that hydrothermal vents like those are almost certainly present on the floor of Enceladus and they were the cradle for life on Earth.
Alvin has had many accomplishments since it was first built in 1964, including aiding in the recovery of a lost hydrogen bomb, discovering previously unknown chemosynthetic life at hydrothermal vents and other seafloor locales, exploring the wreck of the RMS Titanic, and examining impacts to deep-sea life after the Deepwater Horizon oil spill.
The mini-oceans, filled with mixtures that mimic the Earth's primordial ocean, allowed the scientists at NASA to recreate hydrothermal vents and the same alkaline nature the Earth's ocean once had.
Hydrothermal vents are great study sites to investigate metal stress to biota in an un-manipulated 'natural laboratory.' Hydrothermal systems along volcanic island arcs have mostly shallow water depths and strong magmatic input into their fluids and hydrothermal plumes.
Gastropods were collected at two hydrothermal vents sites on the Central Indian Ridge by the human-occupied vehicle (HOV) Shinkai 6500, using a suction slurp gun during the R/V Yokosuka cruise YK16-E02.
Tiny colonies of microbes that dwell near our planet's hydrothermal vents can tolerate a simulated Enceladus habitat, according to a new report by a team of researchers in Austria and Germany.
Among their topics are methane seeps in a changing climate, the shallow submarine hot vent system off the Greek island of Milos as a natural laboratory for studying hydrothermal geomicrobiology, life in serpentinite hosted alkaline springs, microbial nitrogen processes at submarine hydrothermal vents, and multiplication is vexation: a genomic perspective on cell division and DNA replication in the large sulfur bacteria.
After South Georgia, Will later returned to Antarctica as part of a team on the UK science vessel James Cook to locate and investigate hydrothermal vents on the sea bed.
On Earth at least, hydrothermal vents thrive with microbial life, offering up the potential that icy moons far away from Earth " dubbed"OceanWorlds" by NASA " could be habitable.
LIFE could exist on one of Saturn's moons, Enceladus, around hydrothermal vents similar to those found at the bottom of Earth's oceans, scientists believe.
