Section 6 Ocean Primary Production
primary production in the deep sea. Hydrothermal vents—hot springs associated with spreading ridges on the sea floor—support exotic chemical-based ecosystems. The thriving communities associated with these vents shocked the scientific world when humans first observed a vent on the deep ocean floor in 1977. These vent ecosystems depend on ...

Chemosynthesis
oceanexplorer.noaa.govcoast of Ecuador found hot vents on the ocean floor spewing a chemical soup of hot fluid. Surrounding these hydrothermal vents was a community of several new animal species— thriving despite living in total darkness with no access to sunlight! These incredible communities have since been found at spreading centers and
Factsheet: Hydrothermal Vents
oceanexplorer.noaa.govThis sighting was a phenomenon . that had been predicted but never before confirmed. To their amazement, the scientists also found that these vents were surrounded by large numbers of organisms that had never before been seen. A diverse ecosystem was thriving here—in the absence of the sunlight
