When you watch footage from the Pacific Ocean’s bottom, an odd thing happens. Transparent worms, spectral corals, and sea cucumbers floating like abandoned artifacts are among the creatures that appear to be from a different planet. It is completely dark. It’s crushing pressure. Millions of potato-sized metal lumps that have been silently forming for tens of millions of years are dispersed throughout the seafloor in what resembles a pebble driveway.
One of the more intricate resource disputes of our day revolves around those lumps.
The Metals Company, a company that claims to be at the forefront of this industry, recently started private talks with the Trump administration to avoid the United Nations body that oversees international seabed rights, bringing the long-brewing Deep Sea Mining Controversy into sharper relief. Environmental organizations protested the move, several countries responded diplomatically, and there was a predictable wave of confusion about who exactly has the power to approve mining in waters that technically belong to no one.
The metals in question—copper, cobalt, nickel, and manganese—are also required for military hardware, batteries for electric vehicles, and a variety of technologies that governments are increasingly viewing as strategic necessities. The demand for these minerals is expected to increase significantly over the next several decades, according to projections made by the International Energy Agency.
Companies have been drawn to the Clarion-Clipperton Zone, a large area of the Pacific Ocean between Mexico and Hawaii where seafloor nodules are most concentrated, based solely on that forecast. The entire amount of what’s down there is estimated to be worth sixteen trillion dollars. It’s the type of number that tends to irritate people.
The engineering involved is truly remarkable. The nodules are effectively vacuumed up, miles of industrial tubing are extended toward the seafloor, and a bus-sized robot is lowered from a ship. The Metals Company showed journalists from The New York Times three-dimensional models of their machinery, which says something about transparency or how desperately they need positive press at this time. At least under test conditions, the technology functions. It is still very much up for debate whether it can operate profitably on a commercial scale without causing catastrophic environmental harm.
Environmentalists contend that mining the seafloor would permanently damage one of the planet’s least understood ecosystems. In what The Metals Company described as intentional interference, Greenpeace, which has been especially vocal in its opposition to the company, boarded one of its research ships in the Pacific. In response, the company worked to have Greenpeace removed from its observer status in the International Seabed Authority, a UN body that was established thirty years ago and has since been ratified by over 160 countries. Just that disagreement sums up the tone of the entire discussion.
Even though it isn’t entirely convincing, there is an industry argument that should be taken seriously: land-based mining has a negative past. Destroyed communities, poisonous runoff, and child labor. The argument is that there may be less overall harm if deep-sea mining lowers demand for terrestrial mining. Environmentalists argue that rather than replacing current land mining, deep-sea operations would only increase it. Which scenario is more likely is still unknown and most likely won’t be until the industry is up and running.
There’s no denying that the discourse has changed. Businesses that previously presented this as a clean energy story are now using language related to national security because China holds a sizable portion of the world’s essential mineral supply and there is actual geopolitical pressure. It is difficult to determine whether that framing is strategic or genuine. Most likely both.
Even with US licenses possibly on the horizon, commercial deep-sea mining is still years away from reaching large-scale operations. Commercial fleets do not yet exist. The nodules cannot be processed by many refineries. Environmental organizations are likely to file legal challenges, and a change in US administration could completely change the direction. Regardless, the ocean floor will remain patient in a way that can only be measured in geological time. The question is whether the decision-makers are working on a comparable timeline or one that is significantly shorter.
