Mapping the Abyss Faster Than Consulting the Islands

The RV Tangaroa cast off from Papeʻete on 29 July and set course north for the Clarion-Clipperton Zone, an abyssal plain between Hawaiʻi and Mexico, flat and lightless. Earth Sciences New Zealand, which took shape from NIWA and GNS Science in 2025, sent its deep-ocean specialists to sea alongside staff from UK Seabed Resources. While mapping the UK2 licence area over 65 days, the crew will sample nodules for cobalt and nickel. Four decades have gone by since the last comprehensive geological survey of that ground.

Across about 133,000 km² of seafloor the subsidiary holds two exploration licences from the International Seabed Authority. Louisiana would fit inside that spread. The ore yields copper and rare earths too. Until Glomar Minerals acquired the subsidiary, Lockheed Martin owned those licences. At the Authority, Chinese state-backed entities account for the largest bloc of exploration contracts. The company and Cobalt Blue Holdings plan domestic refining through their Project Infinity consortium, which has narrowed its options to four candidate processing sites across three states. Commercial recovery has never happened at full scale in American waters, because the Authority has left its exploitation rules unfinished.

Because a 2025 executive order instructed federal bodies to open American offshore minerals to industry, the newly redesignated Marine Minerals Administration put a lease sale on the books. The Bureau of Ocean Energy Management proposes a November auction over a 125,000 km² block near American Samoa, bordering the Rose Atoll sanctuary. Winning bidders may survey and sample. At this stage the bureau approves only exploration, which keeps the November auction short of extraction. Documents from the American Samoa lease sale record the compressed calendar.

David Apatang, who governs a commonwealth of some 40,000 residents, did not learn of these plans from Washington officials. He found them in published documents. Because families in the Northern Mariana Islands live on ocean resources, food security troubles him first. In its first proposal Washington marked out a 140,000 km² block 200 km east of Saipan. Federal planners added a second block of similar size to the west in March. Consultations never took place, according to the governor.

It was the port statute, adopted by Guam legislators this year, that shut deep-sea mining vessels out of the island berths and denied the industry its western Pacific fuelling point. Apatang would consider a comparable measure for the Northern Marianas. Past three miles the seabed lies outside territorial authority. A territory funded and defended by Washington keeps one practical lever, harbour access. In Hagåtña the CHamoru wording of that statute matters to the residents who filled the hearing room during the public consultations.

Sabrina Suluaʻi-Mahuka, who advocates for the environment in American Sāmoa, refuses to price the sea. In the United States House of Representatives the territorial delegate Aumua Amata warns that mining could disrupt fisheries supplying the bulk of local export earnings. Most of her constituents oppose the auction, she reckons. After a career in American diplomacy, Emily Wood advises the governor of Guam. She weighed a mining company pledge of 1% of profits to island communities against the potential damage and judged it negligible.

Pacific governments disagree among themselves. In seabed prospecting Nauru and the Cook Islands lead the world, while Palau and Fiji have pressed the International Seabed Authority for a moratorium. Sāmoa endorses that call. For the Cook Islands the practical case starts with the paperwork, because a royalty schedule attached to a nodule licence must be explicable in Cook Islands Māori to families in Manihiki. Rarotonga signs the licence while Manihiki lives with the terms. Without a plain-language version a village will dispute the payment when it comes. Kore rauka i Tūkao i te vānanga i reira.

Facing the identical commodity cycle, Moetai Brotherson made the opposite calculation for French Polynesia. He declared the exclusive economic zone a Protected Marine Area under IUCN category VI. That zone measures nearly 5 million km², more than 3% of the world total. Within it, 900,000 km² falls under strict category I protection and 186,000 km² around the islands stays reserved for artisanal fishing. Tainui Ātea, upgraded from the managed designation of 2018, bans deep-sea mining outright.

Rāhui gives that prohibition its local logic. The tupuna handed the restraint down. In Tahitian, Polynesians name the sea Moana Nui a Hiva and hold it as the most sacred marae. In January 2026 a partnership with Te Moana Collective committed 1.5 billion CFP francs, or 12.6 million euros, to local governance and to training the mūtoʻi who patrol those waters. Management committees in the Gambier and the Society Islands draw on that fund.

Brotherson and Surangel Whipps Jr of Palau published a joint warning in Nature in 2025. Pacific seabed mining, the two presidents wrote, combines potentially irreversible ecological risk with undemonstrated economic benefit. Under geopolitical tension the arithmetic worsens. At the International Seabed Authority delegates are reopening the mining code at successive sessions. Glomar Minerals has accordingly proposed no commercial recovery, halting this campaign at survey and sampling.

A team on a resource-sector engagement took benefit-agreement obligations and impact findings into two Pacific languages, writing the payment terms out in figures and glossing the technical vocabulary at first mention. First-language checkers corrected the macrons and the ʻokina forms. During the village consultation the facilitators stumbled over an impact summary drafted in specialist style. The team rebuilt it from scratch. Consent survived the second review round because landowners could state the obligations back in their own words.

A buyer gains more leverage from the ports than from title to an orebody, argues the mineral consultant Nicholas Vafeas. Close to 15% of global copper reserves and most known cobalt occur in the Central African Copperbelt, thousands of kilometres from deep-water loading. In Guinea, Chinese firms answered the equivalent problem with a 20-billion-dollar joint venture, building a heavy-haul railway and the purpose-built port of Morabaya. Zimbabwe restricted raw lithium exports, and Congo, copper and cobalt concentrates. Kinshasa still ships through terminals under foreign control.

Ports aside, a community exercises or forfeits its position through the royalty schedule and the grievance clause. No terminal substitutes for those two instruments. Drafting a clause costs little. In review, defending it takes a specialist with the commercial vocabulary. Machine output has made drafting cheap across languages such as Spanish and French. For purchasers wanting evidence instead of assurance, a graded comparison of engines across Pacific Islands languages sets out the payment clause first.

The paperwork begins with a notice of proposed lease sale opening the public comment window and an environmental assessment inviting technical objection. The grievance notice completes the set, giving a fisher a name to petition and a date by which to file. Issued in English, those instruments stay legible to the territorial administration while remaining opaque to the Sāmoan-speaking families whose fishing grounds border the block. When the comment periods close on their published dates, the consent standard known as FPIC shrinks to a signature exercise.

The RV Tangaroa returns to port in early October with samples bound for a resource model. The bureau opens bidding near American Samoa in November. Between those dates the region gains no new harbour and no new veto. A consultation pack in CHamoru and Sāmoan, drafted and reviewed while the comment window is still open, remains available to governments willing to commission it. Guam legislators acted that fast when they closed their berths.
