A black smoker is a type of hydrothermal vent typically found on the sea floor. These vents are often referred to as underwater geysers. Black smokers can get up to 180 feet tall, and they are also considered to have the highest temperature of the hydrothermal vents. The plumes of burning hot water contain multiple kinds of minerals.  Black smokers are given the name because when the molten hot magma heats up the water and pushes it up through the vent. The average temperature of the heated water hovers around 750 °F.  When the sulfide from the molten hot lava hits the colder sea water, it turns the water leaving the vents black.
Black smokers are found along the mid-ocean ridges. The two main locations for the mid-ocean ridges are the East Pacific Rise and the Mid-Atlantic Ridge. The reason that black smokers are typically found in these areas is due to the fact that these areas are where the tectonic plates meet. The first black smoker was found in 1979 along the Mid-Atlantic Ridge.  The Mid-Atlantic Ridge is located about halfway between the Americas and Europe and Africa. It is formed from where two main tectonics plates meet forming a ridge. Black smokers tend to be at depths of an average of 2100 meters. The key to black smokers is that they tend to appear in clusters. When they discovered the first black smoker, they also discovered the first cluster containing 6 chimneys 12 to 14 meters high. 
Types of organisms Being that the area is so dark, there is not any light for the tubeworms to draw its energy from. The way that the tubeworms draw their energy is similar to that of how a plant gets its energy from photosynthesis. The only difference between the way the tubeworm gets energy and photosynthesis is that the tubeworm gives off sulfur instead of oxygen as a bi product.
Right now the ecosystems in the areas surrounding the Black smokers are in danger. Companies are mining in the surrounding areas near the black smokers. They are mining sulphide from the deposits located in the surrounding areas. This mining could contaminate and smother the areas surrounding the black smokers. Another reason why companies are mining in these areas is that there may be signs of high-grade copper and gold near the hydrothermal vents. Any sort of mining in these areas not only puts the vents in danger, but also the ecosystems where the deep sea organisms live.  Main scientists believe that these vent's may be a key to the origin of life, and that's why they want to protect the environments.
