Examples of hydrothermal vent in the following topics:
-
- A hydrothermal vent is a fissure in the earth's surface from which geothermally heated water issues.
- However, hydrothermal vents often expel nutrient rich water, containing methane and sulfur compounds.
- These bacteria form the basis of the entire hydrothermal vent ecosystem.
- Hydrothermal vents are some of the most unique ecosystems in the world
- Hydrothermal vents are cracks in the earth's crust where geothermally heated water leaks out.
-
- Microbial life plays a primary role in regulating biogeochemical systems in virtually all of our planet's environments, including some of the most extreme, from frozen environments and acidic lakes, to hydrothermal vents at the bottom of deepest oceans, and some of the most familiar, such as the human small intestine.
- Recently there has been the discovery of abundant marine life in the deep sea, especially around hydrothermal vents.
- Large deep sea communities of marine life have been discovered around black and white smokers – hydrothermal vents emitting typical chemicals toxic to humans and most of the vertebrates.
- Hydrothermal vents along the mid-ocean ridge spreading centers act as oases, as do their opposites, cold seeps.
-
- Nanoarchaeum equitans is a species of marine Archaea discovered in a hydrothermal vent off the coast of Iceland.
- Nanoarchaeum equitans is a species of marine Archaea that was discovered in 2002 in a hydrothermal vent off the coast of Iceland on the Kolbeinsey Ridge by Karl Stetter.
-
- In deep basaltic rocks near the mid-ocean ridges, methanogens can obtain their hydrogen from the serpentinization reaction of olivine as observed in the Lost City hydrothermal field.
- Methanogens are commonly found in the guts of animals, deep layers of marine sediment, hydrothermal vents, and wetlands.
- Some methanogens, called extremophiles, can thrive in extreme environments such as hot springs, submarine hydrothermal vents, and hot, dry deserts.
-
- The most hardy hyperthermophiles yet discovered live on the superheated walls of deep-sea hydrothermal vents, requiring temperatures of at least 90°C for survival.
- Other hyperthermophile archaea include Pyrolobus fumarii, which lives at 113°C in Atlantic hydrothermal vents, and Pyrococcus furiosus, first discovered in Italy near a volcanic vent.
-
- There have also been numerous environmental sequences of Epsilonproteobacteria recovered from hydrothermal vents and cold seep habitats.
- Often the epsilonproteobacteria living in hydrothermal deep sea-vents exhibit chemolithotrophic features, and they are able to meet their energy needs by reducing or oxidixing chemical compounds.
-
- Thermophiles are found in various geothermally heated regions of the Earth, such as deep sea hydrothermal vents.
- Large populations of animals can be supported by chemosynthetic secondary production at hydrothermal vents, methane clathrates, cold seeps, whale falls, and isolated cave water.
-
- Methanosarcina acetivorans is a versatile methane producing microbe which is found in such diverse environments as oil wells, trash dumps, deep-sea hydrothermal vents, and oxygen-depleted sediments beneath kelp beds.
-
- Thermophiles are found in various geothermally heated regions of the Earth, such as hot springs like those in Yellowstone National Park. and deep sea hydrothermal vents, as well as decaying plant matter, such as peat bogs and compost.As a prerequisite for their survival, thermophiles contain enzymes that can function at high temperatures.
-
- The three main sources of energy and nutrients for deep sea communities are marine snow, whale falls, and chemosynthesis at hydrothermal vents and cold seeps.
