Scientists from the National Oceanography Centre (NOC) have embarked on a month-long research expedition from Costa Rica to the Central Pacific to understand the impacts of deep-sea extraction of polymetallic nodules on the seabed. These are hard rock like materials, highly enriched in metals found on the sea floor.

The Metals Company, an explorer of the world’s largest estimated undeveloped source of critical battery metals, announced that its subsidiary NORI and offshore partner Allseas have successfully concluded the first integrated system test in the Clarion Clipperton Zone of the Pacific Ocean since the 1970s, achieving all significant pilot milestones while collecting approximately 4,500 tonnes of seafloor polymetallic nodules. Over 3,000 tonnes were transported up a 4.3km-long riser system to the surface production vessel, Hidden Gem, while the additional 1,500 tonnes of nodules were purposely left behind on the seafloor as part of the trials.

Allseas has acquired the former 228 meters long ultra-deepwater drillship Vitoria 10000 for conversion to a polymetallic nodule collection vessel.
