Hydrothermal Vents

02.15.2011

Hydrothermal vents are one of the most spectacular features on the seafloor. They form in places where there is volcanic activity, such as along the Mid-Ocean Ridge. Water seeps through cracks in the seafloor and is heated by molten rock deep below the ocean crust to as high as 400°C. The hot fluid rises to the surface and gushes out of the vent openings. This hydrothermal fluid carries with it dissolved metals and other chemicals from deep beneath the ocean floor. Ecosystems have been found thriving at these vents, relying on chemosynthesis rather than photosynthesis.
