The process of chemosynthesis is similar to photosynthesis. Both can be defined as the creation of organic matter from the fixation of inorganic carbon using energy. But what differs is the source of that energy. In parts of the deep sea, primary production is fuelled by chemical energy, rather than energy from the sun. But this can only take place at certain sea-floor environments where the required chemicals are released into the water. The two main examples of such environments are hydrothermal vents, and cold seeps. The former were only discovered in 1977 when scientists were exploring an oceanic spreading ridge near the Galapagos Islands. What they discovered was a hidden world that revolutionised our understanding of how and where life on Earth can exist. Since then, hundreds more vent field have been discovered, often at depths of 2km or more, along Earth’s convergent plate boundaries and at sea-floor spreading regions where the oceanic crust is moving apart.
