Mining nodule-rich mine sites in the best possible manner may reduce the areal extent of the impacted area. Thus, “cherry-picking” by targeting the most economic (and abundant) mine sites within a license area seems to be favorable on a large scale, while “equivalent areas” must be protected.

Manganese nodules « World Ocean Review

The mining, pumping and cleaning of the manganese nodules creates noise and vibrations, which disturb marine mammals such as dolphins, and could force them to flee from their natural area. The sediment-laden water produced by the cleaning of manganese nodules is released into the sea from the ships. A sediment cloud is also created here.

Conceptual Design of TMR-Less Manganese Nodule Mining ...

The Total Materials Requirement (TMR) of the conventional proposed mining method, however, is very high because of the much lifted water with the nodules from the seafloor to the sea surface and the longer transportation from the mining site to the smelting plant.
