Is radiation from polymetallic nodules a concern?
What the science says: New research provides the first comprehensive estimates of effective radiation doses from handling polymetallic nodules across the…
What lives on the seafloor where polymetallic nodules are found?
Polymetallic nodules are found on the abyssal plains that lie beneath some of the deepest parts of the ocean and are…
How long will it take for the seafloor to recover after polymetallic nodule extraction?
In 1978 and 1979, the Ocean Minerals Company (OMCO) trialled the extraction of polymetallic nodules in the Clarion Clipperton Zone. An…
Can the effects of deep-seabed mining be monitored?
Until recently, researchers needed to rely on calculations, computer modelling and laboratory simulations to estimate the impacts of deep-seabed mining. Now,…
What role do mitigation strategies play in shaping environmental decision-making?
Decisions about polymetallic nodule collection depend not only on understanding the baseline environment and potential impacts but also on the strength…
Will deep-sea mineral extraction create sediment plumes?
Sediment is a mixture of minerals and material that covers the deep seafloor. When polymetallic nodules are collected by remotely controlled…
