Beneath the Pacific's surface, a geopolitical minerals race between the United States and China is pressing against the quieter, older urgency of island peoples who depend on those same waters to live. The Trump administration has proposed leasing tens of millions of hectares of deep seabed near Guam, the Northern Mariana Islands, and American Samoa — framing extraction as strategic necessity — while territorial governments and environmental groups warn that science has not yet caught up to ambition.

Trump deep sea mining plan draws fire from Pacific territories
Potential harm to Pacific island communities dependent on tuna fishing and marine resources; environmental damage to marine ecosystems and wildlife.
We can't really trust that because this has been rapidly evolving
Mark
Why is the Trump administration moving so fast on this? What's the actual time pressure?
Mimi
China is already investing heavily in deep sea minerals. The administration sees this as a strategic competition—whoever controls these resources controls the supply chain for batteries and defense tech. Speed matters to them.
Mark
But the territories are saying they don't understand the risks yet. Isn't that a legitimate concern?
Mimi
Completely legitimate. These are ecosystems we've barely studied. The extraction machinery is brutal—it vacuums up the seafloor. The noise alone can disable marine mammals. And these territories depend on fishing. They're being asked to accept risks they didn't create.
Mark
So why doesn't the federal government just wait for more research?
Mimi
Because waiting means China gets ahead. And because minerals are profitable. Once leases are issued, the pressure to actually mine becomes enormous. The territories understand this—that's why they're fighting now, before the leases are even awarded.
Mark
What happens if they refuse to cooperate?
Mimi
They can slow things down through legal challenges, as they're doing in Hawaii. But they're small territories within a larger federal system. Their leverage is real but limited. The court cases might be their best tool.
Mark
And if the mining goes ahead?
Mimi
The tuna industry in American Samoa could collapse. The marine ecosystems could be damaged in ways we won't understand until it's too late. That's what the territories are trying to prevent.
El Pulso
- Washington is moving with unusual speed, proposing 28 million hectares of Pacific seabed for auction near some of the ocean's least understood ecosystems, driven by the fear of falling behind China in the race for critical minerals.
- Territorial leaders are pushing back hard — Guam's lieutenant governor declared unequivocal opposition, while the Northern Mariana Islands' governor demanded rigorous scientific study before any lease terms are accepted.
- Environmental groups filed suit in Hawaii courts on August 19, arguing that federal agencies bypassed proper environmental review, and that mining machinery would poison sediment layers, collapse food webs, and flood deep waters with noise harmful to whales and dolphins.
- American Samoa faces a separate but parallel threat — a 12.4 million hectare lease proposal with contracts set for November — in a territory whose economy is built almost entirely on tuna fishing.
- Territorial governors have 60 days to review proposals, but distrust runs deep: officials warn that lease awards may be a prelude to extraction regardless of assurances, and legal challenges are the primary tool left to slow the process.
Beneath the Pacific's surface, a geopolitical minerals race between the United States and China is pressing against the quieter, older urgency of island peoples who depend on those same waters to live. The Trump administration has proposed leasing tens of millions of hectares of deep seabed near Guam, the Northern Mariana Islands, and American Samoa — framing extraction as strategic necessity — while territorial governments and environmental groups warn that science has not yet caught up to ambition. It is a familiar tension in human history: the speed of competition outpacing the wisdom of consequence, with those closest to the land bearing the cost of decisions made far away.
The Trump administration is moving quickly to claim the Pacific seafloor. The Marine Mineral Administration recently announced plans to auction mining leases across 28 million hectares of ocean bottom near Guam and the Northern Mariana Islands, close to the Mariana Trench. The rationale is strategic: China is competing for the same polymetallic nodules — rich in cobalt, nickel, and manganese — that power batteries, electronics, and military hardware. But the people who live in these territories are not persuaded that urgency justifies the risk.
The Northern Mariana Islands' governor called for extreme caution and demanded scientific baseline studies, transparency, and explicit protections for marine resources before any decisions are made. Guam's lieutenant governor was more direct, declaring unequivocal opposition and expressing open distrust of federal assurances that leases would not automatically lead to extraction. Both governments have 60 days to review the terms — a narrow window against a fast-moving federal process.
Environmental groups filed suit in Hawaii court, arguing that federal agencies never properly assessed the ecological consequences. The concerns are not speculative: mining machinery destroys nearly everything in its path, stirred sediments poison the food web, and even pre-mining surveys introduce noise levels that harm whales, dolphins, and other marine mammals. These are ecosystems science has barely begun to understand.
The stakes are most immediate in American Samoa, where the economy depends on tuna fishing. The Interior Department is already advancing a separate 12.4 million hectare lease proposal for those waters, with contracts expected in November. Legal challenges are underway, but federal momentum has not slowed. What the next 60 days will reveal is whether the territories' limited leverage — litigation, refusal to cooperate, public pressure — can introduce enough friction to make caution matter in a race that Washington has already decided it cannot afford to lose.
The Trump administration is moving fast to claim the seafloor. On Tuesday, the Marine Mineral Administration—a division of the Interior Department—announced plans to auction mining leases across 28 million hectares of ocean bottom near Guam and the Northern Mariana Islands, waters that sit not far from the Mariana Trench. The administration frames this as a strategic necessity: China is competing for the same thing, and the minerals locked in these deep waters—polymetallic nodules that contain cobalt, nickel, and manganese—are essential for batteries, electronics, and military hardware. The race is on. But the people who actually live in these territories are not convinced.
David Apatang, governor of the Northern Mariana Islands, said his government would examine the proposal "with extreme caution." He wants rigorous scientific baseline studies before anything happens. He wants transparency. He wants explicit protections for the marine resources his people depend on. He has 60 days to review the terms. Guam's lieutenant governor, Joshua Tenorio, was blunter: "We're unequivocally opposed to the deep sea mining efforts in this region." He doesn't trust the Interior Department's assurances that mining won't actually begin just because leases are awarded. "This has been rapidly evolving," he told reporters. "I think that this is a matter where we can't really trust that."
The concern is not abstract. Environmental groups filed suit in Hawaii court on August 19, alleging that federal agencies never properly studied what extraction would do to marine life. The machinery, they argue, destroys nearly everything in its path. It stirs up sediments that poison the food web and suffocate the seafloor. Even the exploration phase—the surveys and sonar work that comes before mining—introduces deafening noise into the water that harms whales, dolphins, and other marine mammals. We don't fully understand these deep ecosystems yet. Mining them before we do is, in their view, reckless.
The stakes are concrete for American Samoa. The territory's economy runs on tuna. Governor Nikolau Pula said his government remains opposed to deep sea mining, warning that untested extraction processes could devastate the fishery. The Interior Department is already moving on a separate lease proposal for 12.4 million hectares of American Samoa's seafloor, with contracts set to be awarded in November. The legal challenge is underway, but the machinery of federal approval is already in motion.
What's happening here is a collision between two kinds of urgency: the administration's sense that the US cannot afford to lose a minerals race to China, and the Pacific territories' conviction that they cannot afford to gamble with ecosystems they don't fully understand and economies they depend on. The territories have some leverage—they can refuse to cooperate, they can litigate, they can make noise. But they are small, and the pressure from Washington is large. The next 60 days will show whether caution can slow down a race.
