A showdown over deep sea mining is taking place in the Pacific

Activists from Greenpeace International have boarded a ship that is conducting deep sea mining research in the Pacific Ocean, vowing to occupy the vessel until it abandons the expedition.

It's the latest collision between a nascent industry intent on the seabed for minerals potentially worth trillions of dollars, and environmentalists and scientists who warn that doing so would irreparably harm biodiverse deep sea ecosystems.

The confrontation unfolding on the comes as the expedition's backer, The Metals Company (TMC), prepares to apply to become the first venture licensed to conduct deep sea mining in international waters. TMC has said it will submit its application after a July 2024 meeting of the International Seabed Authority (ISA), the United Nations-affiliated organization that regulates deep sea mining.

The fate of that application remains unclear, as the ISA's 168 member nations (plus the European Union) have yet to adopt regulations governing deep sea mining. Some 24 ISA member countries have already called for a moratorium or pause on the practice, which is getting increased attention as the shift to EVs and other green technology boosts demand for minerals such as cobalt and nickel.

Canadian-registered TMC and other companies holding ISA contracts argue that deep sea mining is less environmentally and socially destructive than terrestrial mining.

The TMC ship boarded by Greenpeace, the MV Coco, is currently located in the Clarion-Clipperton Zone. That vast region between Mexico and Hawaii contains billions of polymetallic nodules, potato-sized rocks rich in cobalt, nickel and other minerals. Aboard are scientists TMC hired to assess the impact of a 2022 test mining operation conducted by a separate vessel, the Hidden Gem, for a TMC subsidiary.

In a statement to Bloomberg Green, the ISA Secretariat said, it "is monitoring the situation, and is in touch with all involved parties to facilitate a prompt resolution."

Greenpeace dispatched its own vessel, the Arctic Sunrise, from Mexico to intercept the TMC ship. The Arctic Sunrise launched kayaks to disrupt the Coco's operation, and on Nov. 25, two activists boarded the vessel and climbed to the top of a winch used to lower equipment into the ocean. They were later joined by two other activists. As of Monday, two Greenpeace members remain onboard the Coco.

"The fact that The Metals Company is pressing ahead despite mounting opposition to deep sea mining, we believe really justifies us shining a light on this and showing the resistance that is growing across the world," Greenpeace deep sea mining campaigner Louisa Casson said in a phone interview from the Arctic Sunrise.

TMC Chief Executive Officer Gerard Barron accused Greenpeace of hypocrisy for insisting on more scientific studies looking at deep sea mining's impacts while interfering with the company's research expedition.

"They're slowing down, and in some cases, stopping the very environmental science most NGOs, and certainly all member states of the ISA, say we need more of," Barron said in a phone interview from London. "So the question is, why are they doing that?"

In a statement to Bloomberg Green, the ISA Secretariat said it "is monitoring the situation, and is in touch with all involved parties to facilitate a prompt resolution."

On Saturday, Barron sent Greenpeace a letter stating that the organization was putting its activists' lives in danger; he also noted that TMC would seek an injunction blocking the protest unless the group stepped down. On Monday, Barron said that a court date had been set but declined to identify when the hearing would take place or in which country. "We are pursuing any legal measures available to us," he said.

ISA Secretary-General Michael Lodge sent a letter to Greenpeace on Sunday expressing concern about the organization's actions, saying the TMC "campaign is aimed at gathering essential scientific and environmental data and observations as mandated by the Authority."

Casson disagreed with the ISA's characterization. "There is a clear difference between scientific inquiry to better understand deep sea ecosystems and a deep sea mining company that has already stated it expects to be mining the ocean within the next few years," she said.

Barron said if the science were to show that mining shouldn't happen, "we as an organization would pivot to something else." But he added that, "Based on the evidence we've seen today, we will absolutely file an application, and the International Seabed Authority will be the ones to decide."

In a separate action on Sunday, Greenpeace asked the Port of Long Beach in California to block the Hidden Gem from docking, as it is transporting nodules collected during the 2022 test mining operation.

"The ship is carrying cargo that may be radioactive and could present a health risk to workers," wrote Greenpeace campaigner Arlo Hemphill in a letter. He cited a 2023 paper published in the journal Scientific Reports that found polymetallic nodules contain radioisotopes and that their inappropriate handling could pose a serious danger.

Barron dismissed that risk. "The levels of radioactive elements in nodules are far lower than would be found in a typical granite kitchen counter," he said, referring to soon-to-be-released study conducted by TMC. "This is another desperate attempt by Greenpeace to blow this out of proportion."
