The Race to Send Robots to Mine the Ocean Floor

• Wired.com by Eric Niiler

The blobs are not rocks, but naturally-occurring metallic nodules that could one day yield metal deposits of cobalt, manganese, and nickel—not to mention scarce rare earth minerals.

As worldwide demand rises for electric vehicle batteries and wind turbines, along with next generation technologies and weapon systems, demand for these metals has taken off. And the seabed is a prime target for those mining operations. Of course, it's no small feat to bring these potato-sized nodules from the bottom of the remote Pacific Ocean, and then sail them to a processing plant where the metals can be extracted.

But leaders of Canada-based mining company DeepGreen Metals and its subsidiary NORI (Nauru Ocean Resources Inc.) think they have figured out how to harvest the nodules without wrecking the deep ocean habitat—and make a profit at the same time.
