The hydrothermal vents are recognized as a type of chemosynthetic based ecosystems (CBE) where primary productivity is fuelled by chemical compounds as energy sources instead of light (chemoautotrophy). [29] Hydrothermal vent communities are able to sustain such vast amounts of life because vent organisms depend on chemosynthetic bacteria for food.
This incredible active hydrothermal vent was imaged for the first time during the Marianas expedition. It was 30 meters high and gushing high-temperature fluid full of metal particulates. This vent was home to many different species, including Chorocaris shrimp, Munidopsis squat lobsters, Austinograea crabs, limpets, mussels, and snails. Date
In 1980 Daniel Desbruyères and Lucien Laubier, just a few years after the discovery of the first hydrothermal vent system, identified one of the most heat-tolerant animals on Earth — Alvinella pompejana, the Pompeii worm. [1] It was described as a deep-sea polychaete that resides in tubes near hydrothermal vents, along the seafloor.
Indeed, the reducing fluid of hydrothermal vents is rich in sulfide, but poor in oxygen, whereas sea water is richer in dissolved oxygen. Moreover, sulfide is immediately oxidized by dissolved oxygen to form partly, or totally, oxidized sulfur compounds like thiosulfate (S 2 O 3 2- ) and ultimately sulfate (SO 4 2- ), respectively less, or no ...
Beside being a hotbed for organic compounds, the newfound site in the Arctic Ocean may be rich in copper and gold deposits.
Hydrothermal vent – Fissure in a planet's surface from which heated water emits; Deep-submergence vehicle – Self-propelled deep-diving crewed submersible; Mid-ocean ridge – Basaltic underwater mountain system formed by plate tectonic spreading; RISE project – 1979 international marine research project
Kiwa tyleri, the Hoff crab, is a species of deep-sea squat lobster in the family Kiwaidae, which lives on hydrothermal vents near Antarctica. [1] The crustacean was given its English nickname in 2010 by UK deep-sea scientists aboard the RRS James Cook, owing to resemblance between its dense covering of setae on the ventral surface of the exoskeleton and the hairy chest of the actor David ...
Loki's Castle is a field of five active hydrothermal vents in the mid-Atlantic Ocean, located at 73 degrees north on the Mid-Atlantic Ridge between Iceland and Svalbard at a depth of 2,352 metres (7,717 ft). [1] [2] [3] When they were discovered in mid-July 2008, they were the most northerly black smoker vents known to science. [4]
