As #Norway Considers #DeepSeaMining, a Rich History of Ocean Conservation Decisions May Inform How the Country Acts
In the past, scientists, industry and government have worked together in surprising, tense and fruitful ways
by Christian Elliott, April 21, 2025
"At the #Arctic #MidOceanRidge off the Norwegian coast, molten rock rises from deep within the Earth between spreading tectonic plates. Black smoker vents sustain unique ecosystems in the dark. Endemic species of long, segmented bristle worms and tiny crustaceans graze on bacteria mats and flit among fields of chemosynthetic tube worms, growing thick as grass. Dense banks of sponges cling to the summits and slopes of underwater mountains. And among all this life, minerals build up slowly over millennia in the form of #sulfide deposits and #manganese crusts.
"Those minerals are the kind needed to fuel the global green energy transition—#copper, #zinc and #cobalt. In January 2024, Norway surprised the world with the announcement it planned to open its waters for exploratory deep-sea mining, the first nation to do so. If all went to plan, companies would be issued licenses to begin identifying mineral deposits as soon as #Spring2025. To some scientists who’d spent decades mapping and studying the geology and ecology of the Norwegian seabed and Arctic Mid-Ocean Ridge, the decision seemed premature—they still lacked critical data on the area targeted for mining. The government’s own Institute of Marine Research (IMR) accused it of extrapolating from a small area where data has already been collected to the much larger zone now targeted
“ 'Our advice has been we don’t have enough knowledge,' says Rebecca Ross, an #ecologist at IMR who works on Norway’s #Mareano deep-sea mapping initiative. She says the decision was based solely on the #geology of the area. Taking high-resolution scans of the seabed and sampling its geology is the first step when research ships enter a new area, but critical biological and ecological research is more difficult and tends to come later—which is the case on the ridge area targeted for mining. Ross says it’s certain that area contains vulnerable marine ecosystems that would be affected by the light and noise pollution and sediment plumes generated by mining. The IMR estimates closing the knowledge gap on the target area could take ten years.
"The same conflict, with a partial scientific understanding misinterpreted and used to justify resource extraction, is playing out in the #Pacific, where mining pilot projects are already underway in international waters. Years before, scientists funded by industry scouted the #seabed there, discovering both valuable minerals and new forms of life."
#Oxygen produced in the #DeepSea raises questions about extraterrestrial life
"Over 12,000 feet below the surface of the sea, in a region of the Pacific Ocean known as the Clarion-Clipperton Zone (#CCZ), million-year-old rocks cover the seafloor. These rocks may seem lifeless, but nestled between the nooks and crannies on their surfaces, tiny sea creatures and microbes make their home, many uniquely adapted to life in the dark.
"These deep-sea rocks, called polymetallic #nodules, don't only host a surprising number of sea critters. A team of scientists that includes Boston University experts has discovered they also produce oxygen on the seafloor.
"The discovery is a surprise considering oxygen is typically created by plants and organisms with help from the sun -- not by rocks on the ocean floor. About half of all the oxygen we breathe is made near the surface of the ocean by phytoplankton that photosynthesize just like land-dwelling plants. Since the sun is needed to carry out photosynthesis, finding oxygen production at the bottom of the sea, where there is no light, flips conventional wisdom on its head. It was so unexpected that scientists involved in the study first thought it was a mistake.
"This was really weird, because no one had ever seen it before," says Jeffrey Marlow, a BU College of Arts & Sciences assistant professor of biology and coauthor on the study, which was published in Nature Geoscience.
As an expert in microbes that live in the most extreme habitats on Earth -- like hardened lava and deep-sea hydrothermal vents -- Marlow initially suspected that microbial activity could be responsible for making oxygen. The research team used deep-sea chambers that land on the seafloor and enclose the seawater, sediment, polymetallic nodules, and living organisms. They then measured how oxygen levels changed in the chambers over 48 hours. If there are plentiful organisms breathing oxygen, then the levels would normally decline, depending on how much animal activity is present in the chamber. But in this case, oxygen was increasing.
" 'We did a lot of troubleshooting and found that the oxygen levels increased many more times following that initial measurement,' Marlow says. 'So we're now convinced it's a real signal.'
"He and his colleagues were aboard a research vessel tasked with learning more about the ecology of the CCZ, which spans 1.7 million square miles between #Hawaii and #Mexico, for an environmental survey sponsored by The Metals Company, a deep-sea mining firm interested in extracting the rocks en masse for metals. After running experiments on board the vessel, Marlow and the team, led by Andrew Sweetman at the Scottish Association for Marine Science, concluded the phenomenon isn't primarily caused by microbial activity, despite the abundance of many different types of microbes both on and inside the rocks.
"#PolymetallicNodules are made of rare metals, including #copper, nickel, cobalt, iron, and manganese, which is why companies are interested in mining them. It turns out, according to the study, that those densely packed metals are likely triggering "seawater electrolysis." This means that metal ions in the rock layers are distributed unevenly, creating a separation of electrical charges -- just like what happens inside of a battery. This phenomenon creates enough energy to split water molecules into oxygen and hydrogen. They named this "dark oxygen," since it's oxygen made with no sunlight. What remains unclear is the exact mechanism of how this happens, if oxygen levels vary across the CCZ, and if the oxygen plays a significant role in sustaining the local ecosystem."

Exclusive- #Trump supporter #ErikPrince reaches deal with #Congo to help secure [steal] mineral wealth
Jessica Donati and Sonia Rolley
Thu, April 17, 2025
Excerpt: "Democratic Republic of Congo has vast reserves of #copper, #cobalt, #lithium and #coltan - a mineral used widely in smartphones, computers and electric vehicles - but has been plagued for decades by violence in its eastern region.
"The agreement between Congo and Prince initially involved a plan to deploy contractors to Goma, the capital of North Kivu province and the largest city in eastern Congo. But Goma is now under M23 control and that plan has been put on hold. M23 controls tracts of mineral-rich territory.
"A source close to the Congolese government told Reuters an initial deployment of Prince's advisers was expected to start in the south, far from the area controlled by #M23 and its allies.
" 'If you just look at Katanga, if you look at Kolwezi down just off the Zambian-Congo border, they claim that there's like $40 million a month in lost revenue of what's going out and what's coming in,' the source said.
"A diplomatic source also told Reuters the first stage of Prince's effort in Congo would focus on securing mines and tax revenues in copper-producing Katanga province.
"One of the sources close to Prince said advisers were expected to deploy with technical experts from a company specialised in testing and inspecting commodities. The advisers would initially target larger mines and expand as revenue collection improved.
"The source did not provide details on how the advisers would tackle corruption in the sector that has long drained revenue that would otherwise flow to the state.
"A source in the office of Congolese President Felix Tshisekedi said an agreement in principle had been signed with Prince, but the details on where and how many advisers would be deployed remained to be established."

**Late Bronze Age Metal Exploitation and Trade: Sardinia and Cyprus**
“_An array of new provenance studies demonstrates the complexity of the Bronze Age metal trade and, taking a maritime perspective, provides the opportunity to reveal how strategically positioned actors such as Nuragic Sardinia managed to dominate sea-borne routes, and gained a prominent and independent international position._”

The first lesson from this excellent reporting: never -ever- "throw away" copper.
We simply cannot afford to. The supply has to last as long as our civilization, and that supply makes a hell of a mess.

A river ‘died’ overnight in Zambia after an acidic waste spill at a Chinese-owned mine.
About 60% of Zambia’s 20 million people live in the Kafue River basin and depend on it in some way as a source of fishing, irrigation for agriculture and water for industry.
Chinese-owned copper mines have been accused of ignoring safety, labor and other regulations in Zambia as they strive to control its supply of the critical mineral.
