Key points Expedition 5C sampled biological communities, organic flux and food web structure from the ocean surface down to the benthic boundary layer above the abyssal seafloor. Researchers conducted the deepest pelagic biota sampling ever performed, reaching depths of 4,000 meters in the…

Key points Polymetallic nodules in the Clarion Cliffton Zone of the Pacific Ocean contain nickel, cobalt, copper, and manganese; a water jet flow lift system collects them while separating and returning seafloor mud. Collected nodules travel via compressed air bubbles through a steel pipe to…

Key points The Metals Company’s processing pilot campaign converts seafloor polymetallic nodules into an alloy containing critical battery metals.

Key points The vessel, a former drill ship acquired and renamed Hidden Gem by strategic partner Allseas, has arrived in Rotterdam. It will undergo conversion into what is expected to be the first ship classified as a sub-sea mining vessel. The ship is intended to recover polymetallic nodules…

Key points ERIAS Group biologist Adrian Hellman leads the biology team collecting samples during Expedition 6A in the Clarion Clipperton Zone. Water collected above box cores is sieved through a 32 micron sieve to retain small animals living near the seabed, while visible organisms like…

Key points CSA Ocean Sciences deployed three moorings in NORI’s exploration area, the longest reaching about 4,000 meters, with the others at 500 meters and 32 meters, to track seasonal water conditions. A 24-bottle water sampling carousel is lowered to about 4,200 meters, collecting…

Key points Mali, a graduate from Sri Lanka with a degree in Fisheries and Marine Sciences, was accepted to the DeepGreen training program subsidized by DeepGreen. As a research assistant at University of Ruhuna’s Department of Oceanography, she joined Crew 6B to conduct initial surveys…

Key points DeepGreen deployed marine monitoring instruments on moorings throughout the water column in the Clarion Clipperton Zone to establish an environmental baseline. In 2019 the company measured the polymetallic nodule resource in its contract areas and derived its first metal from…
