Manganese or polymetallic nodule mining - Cook .

Furthermore, "toxic chemical release would be less in MN (Manganese Nodule) operations, on account of the mining operation being more a dredging of nodules, rather than a physical crushing.". And, "In MN operations any release at the seafloor would be too deep for an effect on fisheries, and release through Processing Returns could be more widely dispersed than if done over a seamount."
