Pioneering nodule mining: Some words on GSR and on what we are doing
Deutsche Version siehe unten Francois Charlet, Global Sea Mineral Resources, Belgium The transition to clean energy technology, the growing population and urbanization are requiring specific metals such as nickel, cobalt, manganese, and copper. Polymetallic nodules contain these metals in a significant quantity. Intuitively, going to the deep seafloor for these metals could make a lot […]
Restoring the deep sea after mining – would it work?
Deutsche Version siehe unten Sabine Gollner, Royal Netherlands Institute for Sea Research on Texel Many of earth’s ecosystems have undergone significant degradation in the past decades and protecting nature is the most effective tool to prevent further loss of biodiversity. On land and in shallow seas there is a growing recognization that we won’t be […]
