In spring 2015, MBARI researchers discovered a large, previously unknown field
of hydrothermal vents in the Gulf of California, about 150 kilometers (100 miles) east of La Paz, Mexico.
Pacific white skate lay their eggs onto the sizzling hot
rocks of hydrothermal vents in the depths of the sea, possibly because the heat speeds up their development
Lost Nucleotides Although Alexander S. Bradley's article «Expanding the Limits of Life» provides a fascinating account of the discovery of microbes in a previously unknown
kind of hydrothermal vent ecosystem on the seafloor, it does not substantiate his claim that the findings hint that life may have originated in an environment like the Lost City hydrothermal vent.
Scientists at Columbia's Lamont - Doherty Earth Observatory have found evidence
of hydrothermal vents on the seafloor near Antarctica, formerly a blank spot on the map for researchers wanting to learn more about seafloor formation and the bizarre life forms drawn to these extreme environments.
While symbiotic relationships in coral reefs have been known for some time, the
discovery of hydrothermal vents in 1977 has spurred an interest in symbiotic relationships, and led to their recognition in many other types of habitats, such as mangrove swamps, mud flats, and sewage outlets.
This graphic depicts the exoskeleton structure of a certain type of deep - sea shrimp able to survive the scalding hot
waters of hydrothermal vents thousands of feet under water.
Image of a hydrothermal vent field along the Arctic Mid-Ocean Ridge, close to where «Loki,» a member of the Asgard group, was found in marine sediments.
Cassini revealed Enceladus, once thought small, cold, and dead, to have more than 100 plumes of hydrogen - rich liquid water erupting from cracks in its icy crust, possible
evidence of hydrothermal vents in its buried sea — a habitat similar to Earth.
Deep - sea organisms including mussels thrive in the extreme
environments of hydrothermal vents and cold seeps which are characterised by high hydrostatic pressure, lack of photosynthesis - derived food, variable temperatures and high concentrations of toxic substances.
«We report for the first time, a unique behavior where the deep - sea skate, Bathyraja spinosissima, appears to be actively using the elevated
temperature of a hydrothermal vent environment to naturally «incubate» developing egg - cases,» the researchers wrote in the journal Scientific Reports on Feb. 8.
The organisms likely survive using mechanisms similar to the ever - increasing parade of creatures that have been discovered living in the total
darkness of hydrothermal vents at the bottom of the ocean, deriving energy from minerals in seafloor rocks.
They can be several tens of metres tall, and grow as minerals are deposited when the hot water meets the cold ocean water at the
outlet of the hydrothermal vents.
Clague's and Vrijenhoek's dives revealed at least three different
types of hydrothermal vents in the southern Gulf of California — black smokers, carbonate chimneys, and hydrothermal seeps.
An international team of scientists from seven universities and three research institutes has released the first images to the public of a
collection of hydrothermal vents in the Indian Ocean.
Discovered in 1996, this biological hot spot is composed of a
series of hydrothermal vents that dot a volcanic ridge some 200 miles off the coast of Washington State.
At the time of their designation, the largest of the sites was the 95,000 - square - mile Marianas Trench monument near the Northern Mariana Islands and Guam, an area that has been compared to an underwater Yellowstone and Grand Canyon for its unique
geology of hydrothermal vents, mud volcanoes and pools of boiling sulfur.
Other manned submersibles can not dive deeper than about seven kilometers, says Lutz, who has made more than 85 underwater voyages on board the mini sub Alvin and was part of the first deep - sea
exploration of hydrothermal vents in 1979, when he was a postdoc at Yale University.
Thijs Ettema at Uppsala University, Sweden, and his team discovered the new organisms when they analysed DNA extracted from underwater sediment near Loki's Castle, a
region of hydrothermal vents along the Arctic mid-ocean ridge (Nature, DOI: 10.1038 / nature14447).
Our observations and models demonstrate an unexpected influence of surface - generated mesoscale eddies in the
transport of hydrothermal vent efflux and of vent larvae away from the northern East Pacific Rise.
Moreover, Wright has traveled the world to examine fissures along mid-ocean ridges, hoping to unravel the
mysteries of hydrothermal vents and underwater volcanic eruptions.
After analyzing the water temperatures and the locations of the eggs, the researchers realized that these littered in hot water around known
locations of hydrothermal vents, an opening in the sea floor out of which geothermally heated water flows.
Subsequent explorations by the deep - sea submersible Alvin revealed not only the
presence of hydrothermal vents, but also a startling array of giant worms, clams, and mussels.
Although less than 1 % of the sea floor where hydrothermal vents are suspected has been investigated,
hundreds of hydrothermal vent fields have been identified around the globe in the past couple decades.
«Such widespread and oft - repeated
pulses of hydrothermal venting may stimulate microbial blooms on abyssal hill fault scarps, thus providing a potential food source for ridge flank biota, and an opportunity for researchers to sample the biosphere below the sea floor.»
At Ferraria, the contours of São Miguel's rocky western shore form a well - known piscina, or natural swimming pool, sheltered by basalt crags and fed by a
set of hydrothermal vents.
The new version of Google Earth allows users to mouse around under and over the seas, click on video
clips of hydrothermal vents, read up on which seafoods are being harvested unsustainably, look at marine dead zones and sanctuaries and the like.
1 Around Hydrothermal Vents The scalding hot, sulfur - laden
waters of hydrothermal vents, where ocean water heated by magma reemerges through cracks in the seafloor, are teeming with microscopic life.
Studies of life in hydrothermal vents and of the
chemistry of hydrothermal vents have provided no information about the evolution of RNA and DNA and of their nucleotides from inorganic and simple organic molecules.
