Iron and sulfide nanoparticle formation and transport in nascent hydrothermal vent plumes

There has been much interest recently in the transport mechanisms of metals from hydrothermal vents. Here the authors found that nanoparticulate pyrite is not removed from the plume and can account for over 50% of filtered iron one metre from the vent mouth.

Hydrothermal vents as a kinetically stable source of iron-sulphide-bearing nanoparticles to the ocean

Hydrothermal vents emit metals such as iron to the ocean. A chemical analysis of hydrothermal fluids suggests that up to 10% of the iron is present as stable, iron-bearing nanoparticles.

Impacts of hydrothermal plume processes on oceanic metal cycles and transport

Characterization of hydrothermal plumes in terms of redox, rather than distance from the vent, illuminates the dominant transport processes and fate of metals, focusing on iron and manganese.

Extent of impact of deep-sea nodule mining midwater plumes is influenced by sediment loading, turbulence and thresholds

The extent of impact by midwater discharge plumes from deep-sea nodule mining will be influenced by the quantity of plume sediment, ocean turbulence and acceptable environmental thresholds, according to numerical modelling and direct experiments
