  • In their study, Stratmann and her colleagues used data from a variety of existing surveys as well as deep seafloor imagery from two regions of the Pacific Ocean that are rich in manganese nodules.
  • Stratmann and her colleagues examined two nodule-rich regions in the Pacific Ocean, the Clarion-Clipperton Zone and the Peru Basin.
  • Removal of the nodules and thus the sponges, as would be the case through deep-sea mining, would trigger a cascade of negative effects on the ecosystem.
