More on the topic

The Marine Mineral Resources Strategy Group is a discussion and priority-setting forum for research into marine mineral deposits (manganese nodules, massive sulphides, ferromanganese crusts, phosphorites), their resource potential and all other aspects of deep-sea mining, including environmental impact assessments. Our aim is to contribute to a better understanding of these resources in one of the least understood areas of the world.
