What does a hydrothermal vent do?
Hydrothermal vents support unique ecosystems and their communities of organisms in the deep ocean. They help regulate ocean chemistry and circulation. They also provide a laboratory in which scientists can study changes to the ocean and how life on Earth could have begun.
How do animals survive in hydrothermal vents?
Organisms that live around hydrothermal vents don’t rely on sunlight and photosynthesis. Instead, bacteria and archaea use a process called chemosynthesis to convert minerals and other chemicals in the water into energy.
What is the black smoke in black smokers?
The black “smoke” is caused the presence of iron and sulfur, which combine to become iron monosulfide, which has a black color. When the iron monosulfide solidifies, it created the black chimneys. “White smokers” are the cooler cousins of black smokers. These vents release cooler water then “black smokers”.
What is the temperature in a hydrothermal vent?
Hydrothermal fluid temperatures can reach 400°C (750°F) or more, but they do not boil under the extreme pressure of the deep ocean. As they pour out of a vent, the fluids encounter cold, oxygenated seawater, causing another, more rapid series of chemical reactions to occur.
What chemicals do hydrothermal vents release?
The water from the hydrothermal vent is rich in dissolved minerals and supports a large population of chemoautotrophic bacteria. These bacteria use sulfur compounds, particularly hydrogen sulfide, a chemical highly toxic to most known organisms, to produce organic material through the process of chemosynthesis.
What is a black smoker hydrothermal vent?
Hydrothermal vents form at locations where seawater meets magma. A venting black smoker emits jets of particle-laden fluids. “Black smokers” are chimneys formed from deposits of iron sulfide, which is black. “White smokers” are chimneys formed from deposits of barium, calcium, and silicon, which are white.
Which gas is being emitted from hydrothermal vents?
These heat-loving microbes (which grow optimally at temperatures above 100°C) get their energy from hydrogen gas and produce hydrogen sulfide from sulfur compounds from the vents. Hydrogen sulfide is highly toxic to most animals, including people.
What do hydrothermal vents remove?
Hydrothermal vents also add some elements to the ocean. Scientists showed, for example, that the vents remove elements such as magnesium and sulfur from seawater (which are put there by rivers). These elements get incorporated into seafloor rocks.
