The location of an underwater volcanic vent, marked by a low-lying plume of shimmering water, has been revealed by scientists at the National Oceanography Centre, Southampton. Many types of organisms coexist in near the hydrothermal vents. The basis of the ecosystems are chemo auto trophic bacteria . These bacteria break down hydrogen sulfide, a chemical that is found under the crust that is brought up in the vent water , to create car bo hyd rates.
- Deep-sea hydrothermal vents are found along mid-ocean ridges and back-arc basins in all of the world's oceans. Since 1977, when the first deep-sea vent was discovered near the Galapagos Islands, scientists have identified hundreds of vent fields and over 500 species of animals that are new to science. |

- Some deep-sea populations are extremely patchy: For example, hydrothermal vents form where magma rising close to the ocean bottom (where might this occur?) superheats water, dissolving minerals in the surrounding rock (those that dissolve reduced sulfide compounds are termed 'black smokers').
Discovered only in 1977, hydrothermal vents are home to dozens of previously unknown species. Huge red-tipped tube worms , ghostly fish, strange shrimp with eyes on their backs and other unique species thrive in these extreme deep ocean ecosystems found near undersea volcanic chains. These structures are referred to as hydrothermal vents, and the assortment of animals surrounding them are referred to as hydrothermal vent communities. When first discovered in the 1970s, these oases in the deep sea were a complete surprise—Dr. Bob Ballard calls them a far more important discovery than his finding of the wreck of the Titanic!
The Importance of Hydrothermal Vents A long time ago, scientists thought that photosynthesis was the basis of life. Plants would use sunlight to change the carbon dioxide our bodies produced into oxygen that we could breathe. That is, of course, until Further research by Hazen showed that 'the basic molecules of life…are able to form in all sorts of places: near hydrothermal vents, volcanoes, even on meteorites' (ibid.). Because of this, Hazen doubts the reigning theory of origins, which maintains that the first life began, as Darwin wrote in 1871, 'in some warm little pond' (ibid.).

Fumaroles: Fumaroles, or steam vents, are the hottest hydrothermal features in the park. They have so little water that it all flashes into steam before reaching the surface. At places like Roaring Mountain, the result is loud hissing of steam and gases.
Mar 09, 2014 · On contact with cold, oxygenated seawater, the minerals in those hot fluids precipitate to build spire-like deposits called “vent chimneys”, and sometimes produce a “black smoke” of suspended particles that rises and disperses above the vents.
