I keep looking at the map the Bureau of Ocean Energy Management published.
Thirty-one million acres, blocked off in neat rectangles, sitting in the water just beyond American Samoa’s shoreline. Larger than Pennsylvania. Set for auction on November 19th.
Whoever wins gets twenty years to pull cobalt, nickel, copper, and manganese nodules off the seafloor, from ground that has never once been commercially mined by anyone, anywhere.
That’s the trend worth sitting with this week. Deep-sea mining stopped being a someday conversation. It has a sale date now.
So let’s start with the question underneath my question:
Who actually said yes to this? Because the answer is almost nobody who lives there.
Governor Lemanu Mauga put a moratorium on deep-sea mining in American Samoa’s own waters back in 2024. The current governor, Pulaali’i Nikolao Pula, reaffirmed it. The Fono, the territory’s legislature, passed a resolution against deep-sea mining unanimously, House and Senate both, over two days in the summer of 2025. And when the federal government opened a comment period, around 75,000 people responded. Most of them said no.
None of that stopped the lease sale.
Here’s why: the moratorium covers American Samoa’s territorial waters, and the auction sits just outside them, in federal Outer Continental Shelf waters where Washington doesn’t need the territory’s permission.
So you can hold a moratorium, pass a resolution, flood a comment box with 75,000 letters, and still watch the sale proceed on schedule three miles from your reef.
Consultation happened. Consent didn’t.
A commenter in the public record put it plainly: without the power to say no, being consulted isn’t the same as being asked.
Now, what’s actually down there and what happens when you disturb it.
The nodules sit on the abyssal plain, and mining them means dragging collector machines across the seafloor and pumping sediment back up through the water column.
That sediment doesn’t stay put. Plumes have been measured drifting for miles from a single mining track. A 2021 trial found sediment macrofauna density dropped 37 percent and diversity dropped 32 percent inside the disturbed zone, with the surrounding community thrown into disarray well beyond it.
Researchers estimate the plumes could affect over half of local zooplankton and 60 percent of micronekton, the small fish and crustaceans that everything larger eats.
And this is the detail that stays with me: those nodules took millions of years to form. Nobody knows how long the seafloor takes to recover from having them scraped off. Some estimates run in the centuries. Some researchers doubt it recovers on any timescale that matters to us.
Rose Atoll Marine National Monument sits right next to the proposed lease blocks. It’s a nesting ground for threatened species, protected by name, next to water that would be open for industrial extraction for two decades.
Against that, the case for going ahead. Cobalt, nickel, copper, manganese, all critical to batteries and the broader energy transition, and land-based mining for these same minerals is its own mess, tied up in the Democratic Republic of Congo’s cobalt mines and the human cost that comes with them.
Seabed nodules, proponents argue, could be cheaper to extract and lighter on carbon than digging them out of a mountain. That’s a real argument. I don’t think it’s a strong one anymore.
Battery chemistry has been moving away from cobalt and nickel toward iron-phosphate for a few years now, which quietly undercuts the urgency claim. The minerals argument works best if you don’t ask whether the industry it’s rescuing already found a workaround.
And then, liability.
Who pays when a plume smothers a reef three hundred miles downstream, or a fishery collapses because the micronekton did.
Right now, nobody, structurally. The proposed lease terms don’t set aside any share of rental revenue for environmental cleanup. There’s no bonding requirement written into the sale as it stands. Environmental groups and commenters specifically asked BOEM to require mining companies to post restoration bonds before drilling starts, money set aside up front, guaranteed, so remediation doesn’t depend on a company’s solvency or goodwill after the fact.
That request is sitting in the public comment record. It is not, as of this proposal, in the lease.
Compare that to offshore oil, where decades of disasters forced Congress to build a liability and bonding structure most people have at least heard of, even if it’s imperfect.
Deep-sea mining has no equivalent. No company has ever remediated a large-scale seabed plume, because no company has ever caused one at commercial scale.
The first ones to try this will be the first ones to find out what happens when it goes wrong, and right now the financial responsibility for that discovery falls on whoever’s downstream. Which, geographically, is largely American Samoa.
So yes, this is aggressive. Not because deep-sea mining is new as an idea, it’s been theorized for decades, but because moving from theory to an auction date, over a governor’s moratorium, over a unanimous legislative resolution, over 75,000 comments, in eleven months, is not how a government moves when it’s genuinely listening.
It’s how a government moves when it’s already decided.
There’s still a window here. American Samoa’s governor has a consultation period tied to the July proposal, closing around mid-September, before the sale locks in. That’s not nothing. It’s just narrow, and it’s closing while most of the country isn’t looking.
I think about the people who will be swimming past Rose Atoll in twenty years, after the leases run out, wondering what the water used to hold.
