The Pacific island nation that wants to mine the ocean floor
Fringed by sparkling lagoons and palm-shaded beaches, the Cook Islands has opened its vast ocean territory for mining exploration.
Research vessels roam the seas searching for deposits of battery metals, rare earths and critical minerals that litter the deep ocean's abyssal plains.
The frontier industry is likened by some to a modern-day gold rush, and decried by others as environmental "madness."
"The resource in our field is probably in the order of about U.S.$4 billion in potential value," said Chief Executive Hans Smit from Moana Minerals, which converted the sunburst-orange MV Anuanua Moana, previously a supply ship, into a deepwater research vessel.
It is fitted with chemistry labs, sonar arrays and sensors used to probe the seabed for coveted metals.
For two years it has sailed the Cook Islands, halfway between New Zealand and Hawaii, gathering data to convince regulators that deep-sea mining is safe.
While exploration is far advanced, no company has started mining on a commercial scale.
Big business
"I want to be mining before 2030," Smit said from the ship's tower, as whirring cranes loaded wooden crates of heavy gear below. "Absolutely, I think that we can."

Large tracts of seabed around the Cook Islands are carpeted in polymetallic nodules, misshapen black globes encrusted with cobalt, nickel, manganese and other coveted metals.
Demand has been driven by the rise of electric vehicles, rechargeable batteries and durable alloys used in everything from construction to medicine.
The Cook Islands lay claim to one of just four major nodule deposits globally.
The Pacific island nation is "the world's largest and richest resource of polymetallic nodules within a sovereign territory," according to Australia's University of Queensland.
Moana Minerals — a subsidiary of a Texas-based company — owns the rights to explore 20,000 square kilometers within the Cook Islands' exclusive economic zone.
"If we put one mining ship on there, and we started producing metals, we will be one of the largest mines around," said Smit.
'Belongs to us'
Few countries are as reliant on the ocean as the Cook Islands, a seafaring nation of some 17,000 people scattered across a chain of volcanic isles and coral atolls.
Pristine lagoons lure wealthy tourists that prop up the economy, fridges are stocked with fish plucked from vibrant reefs, and local myths teach children to revere the sea.
Many Cook Islanders fear deep-sea mining could taint their precious moana — or ocean — forever.

"I have seen the ship in the harbour," said tour guide Ngametua Mamanu, 55. "Why do we need the mining stuff to destroy the oceans?"
Retiree Ana Walker, 74, feared foreign interests had come to plunder her island home.
"We think that these people are coming over to make money and to leave the mess with us."
Deep-sea mining companies tout the need for critical minerals to make electric vehicles, solar panels and other "green" technologies.
The idea holds some allure in a place like the Cook Islands, where climate change is linked to droughts, destructive cyclones and rising seas.
"If all goes well, there is good that can come out of it. Financially," said third-generation pearl farmer James Kora, 31. "But it relies on how well we manage all those minerals. If the science says it's safe."
'Guinea pigs'
Marine biologist Teina Rongo squinted into the sunlight as his small boat motored past the Anuanua Moana, an emblem of an industry he views with deep distrust.
"We were never about exploring the bottom of the ocean, because our ancestors believed it is a place of the gods," said Rongo. "We don't belong there."
Deep-sea mining companies are still figuring the best way to retrieve nodules that can lie 5 kilometers or more beneath the waves.

Most focus on robotic harvesting machines, which scrape up nodules as they crawl the ocean floor.
Critics fear mining will smother marine life with plumes of waste, and that the alien noise of heavy machinery will disrupt oceanic migrations.
Environmentalist Alanna Smith said researchers knew very little about the deep ocean.
"We'd really be the guinea pigs of this industry, going first in.
"It's a risky, risky move."
Powerful friends
A U.S.-backed research expedition in the 1950s was the first to discover the "enormous fields" of polymetallic nodules in the South Pacific.
Waves of Japanese, French, American and Russian ships sailed the Cook Islands in the following decades to map this trove.
But deep-sea mining was largely a fringe idea until around 2018, when the burgeoning electric vehicle industry sent metal prices soaring.
Mining companies are now vying to exploit the world's four major nodule fields — three in international waters, and the fourth in the Cook Islands.
The International Seabed Authority meets this month to mull over rules that could pave the way for mining in international waters.
Although the Cook Islands can mine its territory without the authority's approval, it still has a stake in the decision.
The Cook Islands also own one of 17 contracts to hunt for nodules in the international waters of the Clarion-Clipperton Zone, halfway between Mexico and Hawaii.
So far, the Cook Islands has said its approach — even in its own waters — would be closely "aligned" with the authority's rules.
But it remains unclear if it will proceed without those regulations.
"We're not setting time frames in terms of when we want to get this started," said Edward Herman, from the Cook Islands' Seabed Minerals Authority. "I think the time frames will be determined based on what the research and the science and the data tells us."
Many of the Cook Islands' South Pacific neighbors want to see deep-sea mining banned.
French President Emmanuel Macron delivered a scathing indictment in June, saying the "predatory" industry was environmental "madness."
But the Cook Islands has powerful friends.
It signed an agreement with China earlier this year for the "exploration and research of seabed mineral resources."
"There was a lot of noise," said Herman, referencing the backlash over the China deal.
"And obviously there's a lot of interest ... whenever China engages with anyone in the Pacific.
"And we understand, we accept it, and we will continue."

New Zealand farmers battle pine forests to 'save our sheep'
New Zealand sheep farmers are fighting to stop the loss of pasture to fast-spreading pine plantations, which earn government subsidies to soak up carbon emissions. Concern over the scale of the farm-to-forest switch led the government to impose a moratorium in December on any new conversions not already in the pipeline. But farmers say forestry companies are flouting the clampdown. Last month, farmers launched a "Save our Sheep" campaign to reverse the loss of productive farmland. Sheep numbers have plummeted to around 23 million, down from a peak of around 70 million in the 1980s, according to official figures. Falling wool prices and rising milk and beef costs initially drove the decline, but the emissions trading since 2008 has added to the strain. The government is now investigating potential breaches of its moratorium by forestry companies, which have been buying up farmland as recently as June. Federated Farmers — a lobby group for rural communities — submitted to the government "a list of properties we believe have been sold for carbon forestry" since the halt, a spokesman said. The federation is concerned about the sale of more than 15,200 hectares (37,600 acres) of farmland, he said. Dean Rabbidge, who runs a farm outside the Southland town of Wyndham, said some of the newly purchased farms had already been planted with pine trees. 'Criminal' "They're just ploughing on ahead, effectively giving the middle finger to the government announcement," Rabbidge said. The moratorium had created a "gold rush," he said. "It's criminal what's happening." Agriculture and Forestry Minister Todd McClay said the government would change the law by October because it had become more profitable to plant pine forests than to farm sheep. "The law will include clarity on what qualifies as legitimate evidence of a pre-December investment and enable any specific cases to be properly assessed," McClay said. "Anyone who has bought land since December 4, 2024, irrespective of whether they also had trees or not, will not be able to register this land into the emissions trading scheme." Rural New Zealand once abounded with rolling pastures, rickety wire fences hemming in millions of sheep chewing on the green grass. But Rabbidge said those days were gone. "You won't see anything now," he said. "You're just driving through long pine tree tunnels — shaded, wet, and damp." New Zealand is one of the rare countries to allow 100% of carbon emissions to be offset by forestry. "We're not anti-planting trees," said sheep farmer Ben Fraser. "There are areas of land that should be retired, that aren't necessarily productive." But the trading scheme had driven an excessive loss of sheep pastures to forestry, he said. "That's the issue here." 'So short-sighted' Fraser, who farms near the North Island town of Ohakune, said he had seen an exodus of people from the district in recent years. "Since 2018, there've been 17 farms converted to forestry," he said. "That's about 18,000 hectares gone. So you're looking at about 180,000 sheep gone out of the district, plus lambs." The loss of sheep impacted the region. "If the farms thrive, then the towns thrive because people come in and spend their money," he said. "You've got farm suppliers, your fertilizer guys, your supermarkets, your butchers, all of that stuff struggling. "The local schools now have less kids in them. The people who stayed are now isolated, surrounded by pine trees." Rabbidge said the same was happening in Southland. "This whole thing is just so short-sighted," Rabbidge said. "Businesses here are forecasting anywhere between a 10 and 15% revenue reduction for the next financial year, and that's all on the back of properties that have sold or have been planted out in pine trees," he said. 'Lamb on a plate' "Think of all the shearers, the contractors, the transporters, the farm supply stores, the workers, the community centers, the schools, rugby clubs. Everything is affected by this." Government figures from 2023 show agriculture accounted for more than half of New Zealand's total greenhouse gas emissions. But farmers argue they have been working hard to reduce emissions, down more than 30% since the 1990s. "I could put a leg of lamb on a plate in London with a lower emissions profile, transport included, than a British farmer," Rabbidge said. "We just use our natural resources. We're not housing animals indoors and carting feed in and manure out. "Everything's done outside and done at low cost, low and moderate intensity."

The Pacific island nation that wants to mine the ocean floor
A 1,000-ton ship is exploring the far-flung South Pacific for riches buried beneath the waves, spearheading efforts to dredge the tropical waters for industrial deep-sea mining. Fringed by sparkling lagoons and palm-shaded beaches, the Cook Islands has opened its vast ocean territory for mining exploration. Research vessels roam the seas searching for deposits of battery metals, rare earths and critical minerals that litter the deep ocean's abyssal plains.

Restoring sea floor after mining may not be possible, researchers warn
Scientists present at the latest effort to hash out international rules for deep-sea mining say it's unclear if it's possible to restore damaged sea floor ecosystems — or how long it would take. One of the last wild zones on the planet, the sea floor is a coveted frontier for companies and countries eager to access minerals that are in high demand for emerging technologies such as electric cars. Particularly coveted are potato-sized nodules containing cobalt, nickel, copper and manganese, that are found in abundance on the seabed in the central Pacific Ocean. Companies eager to vacuum up these polymetallic nodules say they can do it with minimal risk to the deep-sea environment. But ocean defenders have battled against what they see as the advent of an industry that will threaten isolated ecosystems that are not yet well understood. That threat was underscored by European scientists who presented findings last week on the sidelines of a meeting in Kingston, Jamaica of the International Seabed Authority, which is trying to finalize future rules for seabed mining. "If we remove nodules from the seabed, we do not know what we lose, only that it's lost forever," was one of the conclusions of DEEP REST, a sea floor conservation research project. The DEEP REST study cautioned against using seabed restoration "as a management action for impacted habitats." "So far, all the restoration operations we have attempted within our DEEP REST project have been short-term. And what we observed, is that in the given time, that is to say a few years, the ecosystems do not recover," said Jozee Sarrazin, a researcher at the French Institute for Ocean Science, or Ifremer. "If restoration is possible, it will take a very long time, and at the moment we don't have the data to be able to say if that will be 100 years or 1000 years," the DEEP REST coordinator said. Companies are eager to vacuum up polymetallic nodules — which contain cobalt and nickel, crucial materials for batteries — from the ocean floor. | AFP-JIJI Despite the pressure, the cold, the total darkness, and the lack of nutrition sources at the bottom of the ocean, it is teeming with life. The number of species who live on the deep seabed is not yet known but estimated to be in the millions. Broad swathes of the Pacific Ocean where polymetallic nodules are found shelter fauna such as sponges, soft corals or sea anemones. The fauna "only exists in these areas because they need the hard substrate of the nodule to attach," said Matthias Haeckel of the German research center GEOMAR, which presented results of the MiningImpact project in Kingston last week. Vacuuming up these nodules and spreading sediment over the impacted areas reduces population densities, biodiversity and the functioning of ecosystems, MiningImpact's study found. "To make the story short, in the end, we're talking about recovery times of thousands of years," Haeckel said. The nodules themselves form over millions of years. Some research on restoration efforts is under way but the results are not yet in. "We designed artificial nodules made of deep-sea clay and we placed them at different sites" at depths of about 4,500 meters (14,700 feet), Sabine Gollner, a biologist at the Royal Netherlands Institute for Sea Research, said. "But when you take into account the slow growth rates in the deep sea, the slow processes, it will take quite some more years to find out if restoration is effective and to what degree," she said. Massive deposits of sulfide — a type of mineral deposit found in underwater vents that spit out seawater heated by magma — should be off-limits, the researchers suggest. These types of underwater geysers are teeming with astonishing and unique biodiversity. "If we extract massive sulfides near active vents, we know what we lose, and we must prevent loss," the DEEP REST study says. But according to Gollner, it would be good to incorporate restoration goals into the mining code being negotiated by the International Seabed Authority's member states. "It's good to include it but with a clear statement that at this moment in time, it cannot be taken into account to reach agreed environmental goals," she said. "For example, a contractor shouldn't be allowed to use that argument to mine a larger area."
