3.5.5 impacts of deep-sea mining. the main impacts of deep-sea mining on the seafloor include the depletion or physical damage to the habitat and fauna by the mining equipment, changes in seafloor topography and geochemical characteristics, creation of sediment plumes and potential toxicity from metal and/or process chemicals release (figure 2.6).,deep-sea misconceptions cause underestimation of seabed,scientific misconceptions are likely leading to miscalculations of the environmental impacts of deep-seabed mining. these result from underestimating mining footprints relative to habitats targeted and poor understanding of the sensitivity, biodiversity, and dynamics of deep-sea ecosystems. addressing these misconceptions and knowledge gaps is needed for effective management of deep-seabed mining.
