A recent study in CORAL compares deep-sea polymetallic nodule mining technologies, showing how design choices influence sediment disturbance and deep-sea pollution, and highlighting pathways toward more sustainable mining with reduced seabed impacts.
Deep-sea polymetallic nodules are being explored as a future resource by several international consortia, but existing deep-sea mining technologies are not yet environmentally sustainable. This study compares proposed DSM technologies and key components, highlighting environmental impacts and emphasizing the need for further R&D to improve technical performance and environmental protection.
