NewsBacteria flourish in plumes of deep ocean volcanoes
Deep down in the ocean at tectonic plate boundaries, hot fluids rise from so-called hydrothermal vents. The fluids are devoid of oxygen and contain large amounts of metals such as iron, manganese or copper. Some may also transport sulphides, methane and hydrogen. Source: HACON cruise 2021, REV Ocean ...
