Circulation of hot hydrothermal fluids in fractures and faults of the oceanic crust is driven by temperature and pressure gradients. Fluid discharge is focused to vertical structures, black or white smoker chimneys on the seafloor. Hydrothermal vent temperatures should hypothetically be directly related to water depth. The boiling point of seawater increases with depth and ends at the critical point, ~298.5 bar and ~407°C, which equals a seafloor depth of ~3000 m. As most vent fields are located at a shallower depth, fluid temperatures are expected to follow the boiling curve during ascend to the seafloor. Aim of this work is to identify regions of hydrothermal activity that follow or do not follow the boiling curve as well as explanations ...
