Data on the composition of suspensions of black smokers from different regions of the Ocean are obtained from sampling hydrothermal vents from manned submersibles, remotely operated vehicles (ROV), as well as using sediment traps and in the process of probing with cassette samplers. Differences in the dynamics of the formation and precipitation of sulfide and hydroxide suspensions determine the dependence of the dimensions and configuration of the anomalies of the coefficient of attenuation of light (turbidity) in the hydrothermal plume on the ratio of Fe/S in the solutions.
