US territories hit out at Trump plan to explore deep sea mining in the Pacific

Leaders in the US Pacific territories of the Northern Mariana Islands and Guam are pushing back fiercely against a Trump administration proposal to open millions of hectares of their surrounding seabed for deep-sea mineral exploration, accusing Washington of bypassing local consent and threatening fragile marine ecosystems.

The plan, released by a federal agency, would lease vast tracts of the Pacific floor for prospecting and possible extraction of polymetallic nodules and other critical minerals—elements central to green technology and defense supply chains. But territorial officials say the initiative was advanced without meaningful consultation with the communities that would bear the environmental and cultural costs.

“This is not just about minerals; it’s about sovereignty, livelihoods, and the survival of our ocean heritage,” a spokesperson for the Northern Mariana Islands’ leadership said, reflecting the deep unease across the region.

A Quiet Push for Strategic Resources

The proposal is part of a broader Trump administration effort to secure domestic sources of rare earth elements, cobalt, nickel, and manganese—commodities essential for electric vehicles, semiconductors, and military hardware. With China dominating global processing capacity, the US has sought to diversify its supply chain, and the deep seabed in the western Pacific is seen as a potential frontier.

The US Bureau of Ocean Energy Management (BOEM) is understood to be the lead agency behind the leasing initiative. While the agency has previously overseen offshore oil and gas and wind energy, its role in deep-sea minerals is relatively new and raises fresh legal and regulatory questions, particularly regarding the rights of US territories.

Guam and the Northern Mariana Islands are unincorporated territories, meaning their residents are US citizens but the islands are not full states. Congressional legislation and federal executive orders can directly affect their waters—a point of frustration for local governments that argue they should have a seat at the table.

Environmental and Economic Alarms

Deep-sea mining has long been controversial among marine scientists and conservationists. The proposed lease areas lie in depths where life forms are slow to grow and reproduce, and where sediment plumes from mining operations could smother organisms and disrupt food chains. The NOAA Ocean Exploration program has documented rich biodiversity in these habitats, much of it still poorly understood.

For the islands, the ocean is more than a resource—it is a foundation of food security, tourism, and cultural identity. Local fisheries feed families and drive small economies. Any large-scale mining operation could damage coral reefs, deplete fish stocks, and contaminate waters with heavy metals, critics warn.

“The economic benefits would flow to the US mainland, while the risks would stay right here,” said a Guam-based environmental advocate. “We are not a sacrifice zone.”

Legal and Political Landscape

The legal basis for leasing seabed minerals in US territorial waters hinges on the Outer Continental Shelf Lands Act and other federal laws. However, the proposal also overlaps with international governance frameworks. The International Seabed Authority (ISA) has been developing a global mining code for waters beyond national jurisdiction, but the US is not a party to the UN Convention on the Law of the Sea, complicating its standing in such discussions. The Trump administration’s domestic leasing push appears to sidestep multilateral processes, focusing instead on unilateral action under US law.

Territorial leaders have vowed to challenge the plan through legal, political, and diplomatic channels. They are calling on Congress to require full environmental impact statements and to mandate that local governments give prior informed consent before any seabed leases are finalized.

The pushback also underscores a larger tension in US-Pacific relations: while Washington views the islands as strategic military and economic assets, islanders often feel their voices are ignored in decisions that directly affect them.

What Comes Next

The proposed lease sale is still in a preliminary stage, with public comment periods and environmental reviews ahead. However, territorial officials say they were caught off guard by the timing and scope of the plan, and they are scrambling to organize a unified response.

Environmental groups and deep-sea mining critics are also mobilizing, joining forces with local organizations to amplify the message that the deep ocean should not be treated as a commodity frontier. Several scientists have already called for a moratorium on deep-sea mining until the ecological consequences are fully understood.

As the battle lines form, the Pacific islands find themselves at the center of a global debate over the future of the ocean floor. For them, it is not an abstract policy fight—it is a fight for their home.
