Black smokers, discovered in 1977, bring the deep ocean floor alive. At the bottom of ocean basins, often near sites of volcanic or tectonic activity, these hydrothermal vents emit geothermally heated seawater. The sulfide-rich water jets create chimney-like structures around each superheated plume, supporting a rich ecosystem of hyperthermophiles (the environment can be about 230 degrees Fahrenheit) that survive on chemosynthesis (converting sulfides into energy). French artist Dove Allouche’s eponymous exhibition used photographs of black smokers taken on pioneering oceanographic missions to
