The Communist Chinese Party and the Protection of the Ocean Seabed

A disagreement between deep-sea miner The Metals Company (TMC) and researchers over a new scientific study is threatening efforts to mine the ocean bed for metals critical to supporting the green-energy transition. A study in the journal Nature Geoscience suggested that deep-sea nodules, which contain metals such as nickel critical for electric-vehicle batteries, produce oxygen despite the absence of light at the bottom of the ocean. The researchers making the claim called for further studies into how oxygen is produced on the ocean floor while environmental groups called for a halt to disrupting the seafloor and mining of nodules. TMC and some scientists are questioning the claim and accusing the lead authors of the study of plagiarism… The study comes at a time of troubled waters for the deep-sea mining industry, with political uncertainty and TMC struggling for new sources of investment.

In the U.S., the outlook for the industry has improved recently. On the corporate side, both Tesla and General Motors shareholders have said they wouldn’t back a moratorium on deep-sea mining. Ocean-floor minerals are seen as key to making electric-vehicle batteries because of the presence of cobalt, nickel and manganese in nodules. In Washington in September 2024, a House hearing was held on the subject of deep-sea and critical minerals, as many see the metals found on the ocean floor as important for defense purposes. In a meeting co-chaired by Democrat Kathy Castor of Florida and Republican Robert Wittman of Virginia as part of the Select Committee on the Chinese Communist Party, Barron made the case for deep-sea nodules to become part of the U.S.’s critical mineral supply chain.

Meanwhile, industry leaders have gathered in the Cook Islands in September 2024 where a conference on deep-sea mining is taking place. The Pacific nation is home to thousands of tons of nodules, which are also rich in copper.

Saving the Climate by Fouling the Oceans

The Norwegian government in June 2023 opened the door for deep-sea mining in its waters, despite opposition from environmental groups and a growing list of nation states arguing to ban the practice.  The government said it was proposing parts of the Norwegian continental shelf be opened for deep sea mining and other commercial seabed mineral activities…Companies and countries are scouring the planet to find and secure additional sources of metals and minerals critical for the energy transition, including cobalt, manganese and nickel.  To date deep-sea mining has focused on the extraction of seabed nodules—tennis-ball sized pieces of rock which contain manganese, cobalt and nickel, all of which are used in electric-vehicle batteries. 

So far much of the attention has centered on the Clarion Clipperton Zone in the Pacific Ocean: An area of water between Mexico and Hawaii that contains millions of tons of nodules.  In Norway however, the focus will be on seabed crusts on the country’s continental shelf. The target crusts contain copper, zinc and cobalt, as well as some rare-earth elements, according to the Norwegian Petroleum Directorate…

Countries including France and Germany have called for moratoriums on deep-sea mining, while in May 2023 a report found that when researching the pacific seabed, 90% of the more than 5,000 marine creatures found living in the Clarion Clipperton Zone were new species. Companies including Maersk and Lockheed Martin have also been divesting their deep-sea mining investments.

Mining the Ocean: the Fate of Sea Pangolin

A snail that lives near hydrothermal vents on the ocean floor east of Madagascar has become the first deep-sea animal to be declared endangered because of the threat of mining.  The International Union for Conservation of Nature (IUCN) added the scaly-foot snail (Chrysomallon squamiferum) to its Red List of endangered species on 18 July, 2019 — amid a rush of companies applying for exploratory mining licenses…. The scaly-foot snail is found at only three hydrothermal vents in the Indian Ocean.  Two of those three vents are currently under mining exploration licences,…Even one exploratory mining foray into this habitat could destroy a population of these snails by damaging the vents or smothering the animals under clouds of sediment..

Full-scale mining of the deep seabed can’t begin in international waters until the International Seabed Authority (ISA) — a United Nations agency tasked with regulating sea-bed mining — finalizes a code of conduct, which it hopes to do by 2020….The biggest challenge to determining whether the scaly-foot snail warranted inclusion on the Red List was figuring out how to assess the extinction risk for animals that live in one of the weirdest habitats on Earth…

When the IUCN considers whether to include an organism on the Red List, researchers examine several factors that could contribute to its extinction. They include the size of a species’ range and how fragmented its habitat is…The IUCN settled on two criteria to assess the extinction risk for deep-sea species: the number of vents where they’re found, and the threat of mining.   In addition to the scaly-foot snail, the researchers are assessing at least 14 more hydrothermal vent species for possible inclusion on the Red List.

Gummy Squirrels v. Cobalt: Mining the Seabed for Real

Sometimes the sailors’ myths aren’t far off: The deep ocean really is filled with treasure and creatures most strange. For decades, one treasure—potato-size nodules rich in valuable metals that sit on the dark abyssal floor—has lured big-thinking entrepreneurs, while defying their engineers. But that could change April 2019 with the first deep-sea test of a bus-size machine designed to vacuum up these nodules.

The trial, run by Global Sea Mineral Resources (GSR), a subsidiary of the Belgian dredging giant DEME Group, will take place in the international waters of the Clarion-Clipperton Zone (CCZ), a nodule-rich area the width of the continental United States between Mexico and Hawaii. The Patania II collector, tethered to a ship more than 4 kilometers overhead, will attempt to suck up these nodules through four vacuums as it mows back and forth along a 400-meter-long strip.

Ecologists worried about the effect of the treasure hunt on the fragile deep-sea organisms living among and beyond the nodules should get some answers, too. An independent group of scientists on the German R/V Sonne will accompany GSR’s vessel to monitor the effect of the Patania II’s traverses. The European-funded effort, called MiningImpact2, will inform regulations under development for seafloor mining,…

The nodules are abundant, and they are rich in cobalt, a costly metal important for many electronics that is now mined in the forests of the Democratic Republic of the Congo, a conflict zone…Ideal for nodule formation, the CCZ is estimated to contain some 27 billion metric tons of the ore. But its abyssal plain is also a garden of exotic life forms. Craig Smith, a benthic ecologist at the University of Hawaii in Honolulu, has helped lead biological surveys in the CCZ that, in one case, revealed 330 species living in just 30 square kilometers, more than two-thirds of them new to science. The CCZ’s inhabitants include a giant squid worm,  green-yellow sea cucumbers that researchers called “gummy squirrels,” and a greater variety of bristle worms than ever reported before.

Mining could leave a lasting imprint on these ecosystems. In 2015, MiningImpact scientists visited the site of a 1980s experiment off Peru in which a small sledge was pulled along the bottom to simulate nodule harvesting. Three decades later, “It looked like the disturbance had taken place yesterday,” says Andrea Koschinsky… Many of the species in the deep seabed, such as corals and sponges, live right on the nodules. “They will be sucked up and are gone. You can’t go back.”Such concerns make many environmentalists wary of opening any of the deep sea to mining…

For one thing, the legal framework for mining in international waters is uncertain. Although the United Nations’s International Seabed Authority has granted contracts for exploration, it is still drafting rules that will govern commercial operations and set limits for environmental damage. The rules are unlikely to be final before 2021…

These sensors will focus on the plume of sediment the collector kicks up. The waters of the CCZ are some of the clearest in the world, and scientists have long feared that mining could spread a vast blanket of silt, hurting life far outside the mining area. Recent experiments, however, suggest most of the silt particles will clump together and fall out within a kilometer or two, Koschinsky says. But a film of finer nanoparticles might spread farther.
